    An assembly (100) has a plurality of seats (10a, 10b, 10c), each seat having a chair (11a, 11b, 11c) and having a side box (12a, 12b, 12c) arranged laterally on one side of said chair. The chairs on the one hand and the side boxes on the other hand are arranged in staggered rows in two parallel rows. Each seat having a covering shell (14a, 14b, 14c) defining a rear surface (141) in a rear area of the chair and determining a front surface (142) in a front area of the side box. A gap between a rear surface (141) of a front seat and a front surface (142) of a rear seat forms a passage (21) for a rear seat occupant. In a vertical section, the rear surface (141) and the front surface (142) have convex profiles facing each other, a width L (hz) of the passage increasing in the direction of decreasing heights hz from a height hzmin of the minimum width Lmin, and increasing in the direction of increasing heights hz from the height hzmin.

    Dans cet exemple, la hauteur hzmin (plan de la section 4c) de la largeur minimale est de 330 mm au dessus du plancher.
    Les valeurs ci-dessus ne sont données qu'au titre d'une illustration par un exemple concret d'une forme de réalisation qui procure un confort adapté pour une classe « affaire » dans un aéronef, et elle peuvent être modifiée de plus ou moins 10 mm en conservant un niveau de confort acceptable si la largeur minimale Lmin est diminuée, et légèrement augmenté au pris d'un allongement du pas des sièges si la largeur minimale Lmin est augmentée.
    Ces valeurs peuvent cependant être modifiées par l'homme du métier en plus ou en moins en fonction du niveau de confort qu'il souhaite obtenir ou à l'opposée de contraintes qu'il accepte d'introduire.
    Bien évidemment la valeur de la largeur minimale Lmin du passage 21 à la hauteur hzmin doit respecter une valeur minimale de passage acceptable non seulement pour des raisons de confort vis à vis de l'utilisateur du siège, mais également pour permettre une évacuation d'urgence lorsque des normes sont applicables comme dans la plupart des véhicules de transport collectif, par exemple les aéronefs de transport.
    Il n'y a pas de limite théorique à choisir une valeur plus grande pour la largeur minimale Lmin du passage 21, mais il doit être remarqué que le choix d'une largeur minimale de passage augmentée va à l'encontre de la réduction du pas des sièges recherchée par l'invention et, qu'au delà d'une valeur de passage standard, le confort pour l'utilisateur n'est pas nécessairement amélioré.
    Avantageusement la largeur minimale Lmin du passage 21 est comprise entre 200 mm et 300 mm, les valeurs des largeurs de passage pour les autres hauteurs que la hauteur hzmin étant adaptées pour faciliter la circulation dans le passage 21 comme décrit précédemment.
    Au niveau du plancher, la largeur Linf est avantageusement égale ou supérieure à 300 mm pour le passage des pieds et est élargie par rapport à la largeur minimale, au moins dans la section verticale de largeur minimale, de préférence vers l'avant, c'est-à-dire par la forme de la surface arrière 141 de la structure d'habillage du siège avant 10a.
    Comme le montre l'exemple de réalisation illustré sur la figure 2, les formes des surfaces avant 141 et arrière 142 peuvent être adaptées localement, par exemple au niveau d'un raccordement de la structure d'habillage au plancher. De telle adaptations, sans remettre en cause les principes de l'invention, permettent par exemple de s'adapter à des contraintes de liaisons des structures du siège aux structures du plancher ou de faciliter l'entretien des zones soumises aux matières pouvant être transportées par des semelles de chaussures.
    Il sera toutefois recherché une largeur Linf minimale au niveau du plancher, pour hz=0 si le plancher est pris comme référence de hauteur, de sorte que le passager utilisant le passage puisse passer ses pieds sans risquer de se trouver coincer ou gêner. L'invention permet ainsi d'optimiser l'espace utilisé dans une cabine par un agencement en quinconce des sièges qui permet de réduire la largeur nécessaire pour agencer deux rangées de sièges et par la diminution de la distance nécessaire entre deux sièges d'une même rangée lorsqu'un passage doit être assuré vers une allée de circulation.
    Cette configuration s'avère avantageuse dans le cas d'un ensemble agencé contre une cloison, par exemple en 2+2 passagers de front dans un aéronef, ou lorsque deux ensembles sont juxtaposés, par exemple pour former un agencement en 2+4+2 passagers de front dans un aéronef.
    The invention belongs to the field of fitting passenger spaces of passenger transport vehicles. The invention relates in particular to a set of seats, convertible into beds, having chairs arranged in staggered rows.
    More particularly, the invention relates to an arrangement in which a passage between two successive seats of a row is reduced in width without impairing the comfort of circulation in the passage. The layout of passenger cabins is often confronted with the maintenance of sufficient passenger comfort to offer attractive conditions, particularly when it has to be supported by relatively long journeys, or even travel periods covering a period of sleep.
    Such a situation is likely to be found for example in coach travel, sea crossings and medium or long-haul flights.
    To improve the comfort of passengers in these conditions, including passengers traveling in the upper classes, business classes or first classes, it is known to provide seats that can be converted to more or less complete beds to the will of the passenger by movements relative to the seating of the chair and its backrest.
    It is also known to seek an increase in the density of passengers in a cabin by a staggered arrangement of chairs of two adjacent rows so that when the chairs are converted into a berth, the narrow area of the feet is at the level of wide area of the backrest of a row adjacent which allows to form a set of two rows of armchairs whose total width is less than twice the maximum width of a chair.
    However, in such an arrangement, it is necessary to maintain, between the rear of a seat and the front of a seat located in the rear row, when the seats are in berths, a passage for the occupant the offset seat of the row terraced. The width of this passage is added to the length of the seat converted into a bed to determine the pitch of the seats and penalizes the number of seats that can be arranged for a given cabin length.
    One solution to reduce the pitch of the seats is to reduce the width of the passage, see to delete the passage when the seats are converted into a berth.
    This solution is not acceptable, however, because a passenger away from an alley may wish to leave his seat and must in this case step over the seat that separates it from the driveway or climb on a raised portion forming a step-board, as per example in the solution described in document SUS 2012/0298798 A1.
    The present invention aims to overcome these drawbacks by providing the passenger, for an equivalent sleeping length, a passage adapted to its movements between its seat and a distant alley.
    For this, the invention relates to an assembly comprising a plurality of seats arranged in a row along a longitudinal axis X, each seat comprising an armchair and having a lateral box arranged laterally on one side of the chair, in which together the armchairs of a side and side boxes on the other hand are arranged staggered in two parallel rows oriented in the same direction as the longitudinal axis X of the set of seats.
    In addition, each seat has a covering shell defining a rear surface in a rear area of the seat chair and determining a front surface in a front area of the seat side box.
    All chairs in the same set of seats are oriented with a front side of the chair oriented substantially in the same direction and a space between a rear surface of a front seat and a front surface of a rear seat, located immediately behind. of said front seat as a whole, forms a passage for an occupant of said rear seat.
    According to the invention, in a section formed in a vertical plane in which there is a minimum width Lmin of the passage, the rear surface and the front surface have convex profiles facing each other, a width L (hz) of the passage in said plane. vertical increasing in the direction of heights hz, considered above a reference cabin floor and increasing upwards, decreasing from a height hzmin of minimum width Lmin, at least to near the floor, and width L (hz) increasing in the direction of increasing heights hz from the height hzmin of the minimum width Lmin.
    It is thus reduced the width of the passage, and therefore the distance between two chairs of the same row, limiting the range in height on which the passage is of reduced width to allow a passenger to circulate in the passage without significant discomfort, and by exploiting the reduction of the minimum width of the passage to reduce the pitch of the seats without reducing the length assigned to a passenger for his comfort.
    In one embodiment, the minimum width Lmin of the passage is between 200 mm and 300 mm, and the height hzmin of said minimum width above the floor is between 200 mm and 500 mm. It is thus maintained a sufficient passage width at the lower parts of the lower limbs of a passenger and the minimum width is close to the height of a sleeping plane in a bed position of a chair which is the most demanding in length.
    In one embodiment, the maximum width L (hz) of the passage, in the vertical plane in which the minimum width Lmin of said passage is located, is, for the heights hz less than the height hzmin, between 310 mm and 400 mm. , and said maximum width is located between the floor and a height hz equal to or less than 150 mm, the width L (hz = 0) of the passage at the floor being at least equal to 250 mm. It is thus maintained near the floor a width adapted to the passage of the feet of a passenger flowing in the passage.
    In one embodiment, a minimum value of the width L (hz) of the passage, in the vertical plane in which the minimum width Lmin of said passage is located, is, for the heights hz greater than the height hzmin, of between 300 mm and 400 mm, and said minimum value is reached for a height hz between 600 mm 800 mm. It is thus formed an enlarged passage at height corresponding to also wider parts of the body of a passenger flowing in the passage.
    In one embodiment, the rear surface of the seat upholstery shell in a rear area of the chair of said seat has a convex shape in sections along horizontal planes, giving said rear surface a pseudo-ellipsoidal shell shape. .
    In one embodiment, the front surface of the seat shell of a seat in a front zone of the side box of said seat has a substantially straight shape in sections along horizontal planes, giving said front surface a cylinder shape. part.
    These forms of the covering shell make it possible to create concave volumes of shapes adapted to the physiognomy of the passengers both at the level of the head and the feet, in particular in the lying position, and gives the passage in a top view a convergent shape. -divergent which limits the narrowest length of said passage and guides the passenger during his movement without forming sharp angles.
    In one embodiment, the side casing of a front seat has a rearwardly open volume forming a footwell for an occupant of a rear seat, the chair of which is substantially aligned with said open space due to the staggered arrangement of armchairs and side boxes.
    In one embodiment, a chair is convertible into beds by relative movements of a backrest and a seat of said chair to form with a substantially horizontal surface of the open volume forming a footwell, the side box of the seat in front of the chair seat considered, a sleeping plan.
    In one embodiment, the width L (hz) of the passage, in the section formed in a vertical plane in which the minimum width Lmin of said passage is located, is 324 +/- 10 mm at a height above the floor (23) hz = 130mm, 251 +/- 10 mm for hz = 230 mm, 232 +/- 10 mm for hz = 330 mm, 235 +/- 10 mm for hz = 430 mm, 246 + / -10 mm for hz = 530 mm, 267 +/- 10 mm for hz = 630 mm, 308 +/- 10 mm for hz = 730 mm.
    It is thus formed a set of seats which makes it possible, in particular in a business-class layout of an aircraft having shown its ability to satisfy the desired comfort of access, to propose seats convertible into beds while minimizing the impact. on the necessary space in length and benefiting from the necessary width advantages provided by the staggered arrangement when a single seat in a two-row seat assembly is bordered by a traffic lane. The invention is described in detail with reference to the drawings which show schematically: - Figure 1: seen above, a set of 3 seats according to the invention, the armchairs, oriented substantially in front towards the same direction, are arranged in a staggered pattern along two adjoining rows, the seats being shown in an armchair configuration; - Figure 2: the section AA of the seat assembly of Figure 1, illustrating in a vertical plane the passage formed between a seat and an aisle in its narrowest part; - Figure 3: in profile view, a set of two seats offset longitudinally as shown in Figure 1, and in which view are shown sectional planes at constant heights relative to a reference floor; - Figures 4a to 4g: sections in the horizontal planes at different heights materialized in the profile view of Figure 3 and showing the contours of the envelopes of the seats of Figure 3; - Figure 5: on views in vertical section of the passage in its narrowest part corresponding to the section of Figure 2, passengers of different sizes and morphologies engaged in the passage: view (a) for a small passenger corresponding to the 5th percentile of a passenger sample, seen (b) for a mid-size passenger corresponding to the 50th percentile of the sample and seen for a large passenger corresponding to the 95th percentile of the sample.
    In the figures, the drawings are not necessarily represented on the same scale.
    In the figures of the parts or similar elements, even represented in different forms, bear the same reference mark.
    The figures mainly illustrate the outer forms of the seats of the set and the details elements, in particular the internal structures of the seats, are not shown or only as an accessory for understanding the drawings.
    Figure 1 shows a top view of a set 100 of three seats 10a, 10b, 10c according to one embodiment of the invention.
    In the assembly 100 each seat 10a, 10b, 10c comprises a chair, respectively 11a, 11b, 11c, and has a side box, respectively 12a, 12b and 12c, arranged on one side of the seat.
    As can be seen in FIG. 1, the chairs on the one hand and the lateral boxes on the other hand are arranged in staggered rows along two parallel rows oriented along a longitudinal axis X of an axis system connected to the seat assembly.
    In the assembly considered, the chairs are substantially oriented in the same direction so that passengers occupying the different seats of the seat set all look in the same direction.
    In the rest of the description, reference will be made as often as necessary to a system of axes linked to the set of seats in which a direction of the longitudinal axis X corresponds to a longitudinal direction of the set of seats and therefore to the directions of the longitudinal axes 13d, 13g of the rows of seats of the assembly 100. The longitudinal axis X is oriented positive towards the front of the assembly 100 which substantially corresponds to the front of the seats, the front being the forward direction as understood by an occupant of a chair, all chairs 11a, 11b, 11c of the set considered substantially oriented in the same direction.
    The axis system also has a vertical axis Z, perpendicular to the longitudinal axis X, in a vertical direction and oriented upwardly.
    The axis system has a lateral axis Y in a horizontal plane and oriented positively to the left, for an occupant of an armchair, so as to form a direct XYZ trihedron.
    Each seat, 10a, 10b, 10c comprises a covering structure which determines the volumes occupied by the seat in question and covers, for mechanical reasons as well as for aesthetic reasons, the various functional parts of the chair, respectively 11a, 11b, 11c and the lateral box, respectively 12a, 12b, 12c.
    In the remainder of the description it will, for the sake of clarity, refer to any of the seats of FIG. 1 when the description is directed to an isolated seat, and reference will be made to the seat 10a as a front seat and at the seat 10b as the rear seat when the description is for two seats succeeding one another along the longitudinal direction in the assembly 100. It should be understood that this choice is arbitrary, the various seats of a set being similar, to a symmetry mirror close to a vertical plane XZ between two successive seats in the direction of the longitudinal axis X.
    The lateral box 12a of the seat 10a before has a hollow volume, open towards the rear, and having a horizontal surface forming a footrest 113 on which the occupant of the chair 11b of the seat 10b back, said chair 11b being located behind said box lateral 12a due to the staggered arrangement of the chairs of the assembly 100, can put his feet, especially when said rear seat is converted into a bed, bed configuration in which a seat 112 of the chair, a backrest 111 of the chair and the footrest 113 formed in the lateral box located in front of the chair determine substantially horizontal surfaces and at the same height, relative to a horizontal reference plane 20, to form a coating plane.
    Thus, although associated in the exemplary embodiment illustrated with a seat 10a before for which the side box 12a integrates functions of said seat, such as support functions or side table, storage and integration of easements as for example, power supplies, lighting, control panels or air distribution, not shown, the covering structure, for its part relating to the side box 12a, also determines a maximum forward extension of a rear seat 10b, maximum extension associated with the front end of the bed formed for said rear seat in bed position.
    The covering structure of the rear seat 10b, in the part corresponding to the side box 12b, thus determines a front surface 142 of the covering structure 14b of said rear seat.
    The covering structure of the seat 10a before, in the portion corresponding to the chair 11a, determines a rear surface 141 of the covering structure 14a of said front seat, extension associated with the rear end of the bed formed by said chair in bed position .
    Considering the staggered arrangement of the chairs, and taking into account the mirror symmetry between the two seats 10a, 10b following in the assembly 100, the rear surface 141 of the covering structure 14a of the seat 10a before at the level of armchair 11a, more particularly of the back of said chair, is vis-à-vis the front surface 142 of the covering structure 14b rear seat 10b at the side box 12b.
    Given a pitch Px of the seats in the assembly, corresponding to a separation distance in the longitudinal direction X between SRP reference points of two successive chairs aligned in a seat row of the set, and the length When the bedding of a seat is in the bed position, an intermediate space 21 is determined between the rear surface 141 at the level of the chair 11a of the front seat and the front surface 142 at the side box 12b of the rear seat.
    As shown in the illustrations, the intermediate space 21 forms a passage between the chair 11b of the rear seat 10b and an aisle 22 of circulation relative to said chair on an outer edge of the seat side of the side box 12b of said seat.
    Figure 1 illustrates how a width Lp of the passage 21 depends on the pitch Px of the seats and the length Lo of the bed.
    In the first order, the width Lp of the passage is equal to pitch Px of the seats decreased by the length Lo of the bed and decreased by a thickness Del corresponding to the cumulative local thicknesses of walls of the cladding structures 14a, 14b.
    It is generally accepted that to provide sufficient comfort to a seat occupant the width Lp should be approximately 355 mm (14 "), a value of 305mm (12") of that width being sometimes considered a minimum acceptable for allow a person to travel the short distance between the chair 11b of the aisle 22. In practice, the width Lp is chosen, according to comfort criteria acceptable in the category of seat considered, generally different for the first classes, the "business" classes or "tourist" classes.
    This first approach to the calculation of the width Lp of the passage, however, does not take into account the morphology of the occupant of the seat and the dynamics of its displacement during the passage in one direction or the other between the chair 11b and the aisle 22.
    To reduce the pitch Px of the seats of the assembly 100, without reducing the length Lo of the bed, the shapes of the covering structure of the seats are adapted, as in the example shown, to reduce the width Lp of the passage 21 while retaining for a seat user a comfortable passage 21 for its movements from or to the aisle 22.
    FIG. 2b shows the external shapes of the cladding structures 14a, 14b in a vertical section, marked AA in FIG. 1, in a zone of the narrower passage 21, and in particular shows the rear surface 141 of the structure of FIG. dressing 14a of the front seat in the area of the chair and the front surface 142 of the dressing structure 14b of the rear seat in the area of the side box.
    As illustrated in the vertical section of FIG. 2, the two rear surfaces 141 and 142 are convex in the zone considered so as to determine a width L (hz) of the passage 21 which is a function of a height hz above a cabin floor 23 on which the seat users move, floor which can correspond to the horizontal reference plane 20 as in the following description, or be offset by a constant with respect to said horizontal reference plane.
    The convex shapes of the rear surfaces 141 and front 142 facing each other determine in the vertical plane of the narrowest passage zone a minimum width Lmin of the passage 21 located at a height hzmin above the floor 23.
    To allow the comfortable passage of the lower part of the lower limbs advantageously the minimum width Lmin is between 200 mm and 300 mm, the latter value being limited mainly to not unnecessarily increase the pitch of the seats, and said minimum width Lmin is located at a height hzmin between 200 mm and 500 mm above the floor.
    Due to the convexity of said front and rear surfaces, the width L (hz) of the passage 21 increases in the direction of the decreasing heights hz from the height hzmin of minimum width and also increases in the direction of increasing heights hz from said height hzmin . The widening of the passage under the height hzmin minimum width allows a person to have in the passage 21 of an enlarged volume of increased width relative to the minimum width in the area of the passage of his feet. This enlarged area prevents a foot from catching and the person stumbles.
    To maintain the ability of a passenger to move laterally in the passage, the maximum width of the passageway width near the floor is between 310 mm and 400 mm and the maximum width that allows the passage of the feet is between the floor and a height of 150 mm above the floor. The passenger can thus lift, at least slightly, his feet when moving in the passage and it will also be chosen to determine the floor Linf width of at least 250 mm to allow him to put his feet on the floor itself in the minimum width section of the passageway, or move it without hooking structures. The widening of the passage above the height hzmin of minimum width makes it possible to have at the level of the lower limbs and the pelvis of a person (having average morphological characteristics) an equally enlarged volume of increased width compared to at the minimum width in the area of the passage of his feet.
    In particular at the level of the upper part of the lower limbs, a width Lsup of the passage will advantageously be between 310 mm and 410 mm, the said width Lsup being obtained for a height above the floor of between 600 mm and 800 mm, advantageously substantially a height of the lateral box 12b above the floor 23 of the order of 730 mm as in the example illustrated in the figures.
    This enlarged area allows the person to have greater ease at the upper level of the lower limbs and pelvis, the dimensions of which are greater than those of the lower parts of the lower limbs, and which are subject to swaying when the person moves. .
    It should be noted that between the height hzmin and the level of the floor 23, corresponding to a zero value of the height hz, the width of the passage can be increased rapidly and with a suitable amplitude provided that it is not created. interference with equipment or structures of the wheelchair forward and the side box to the rear.
    These different conditions on the shapes and dimensions of the passage 21 in its narrowest part are illustrated in the drawings of Figure 5 in conditions of use by passengers of different sizes and morphologies. View (a) of Figure 5 shows a small passenger corresponding to the 5th percentile of a passenger population, the view (b) a mid-size passenger corresponding to the 50th percentile, and the view (c) a large passenger. size corresponding to the 95th percentile. In these three cases covering 90% of the population considered, it may be noted that the person is not hampered in his movement in the passage 21 despite the narrowness of the passage.
    In addition, the minimum width of the passage 21 affects only a vertical section of the passage.
    As can be seen in the top view of FIG. 1, the rear surface 141 of the front seat trim structure 14a is also curved in a horizontal plane XY and has a convexity that is combined with the convexity in the vertical plane. at the said structure in the area considered a pseudo-ellipsoidal shape, more particularly the rear surface 141 approximates a convex surface of ellipsoid cap.
    The curved shape of the rear surface 141 of the covering structure in the area of the chair corresponds to a concave shape in the area of the head of a seat occupant, when the chair 11a is converted into a bed, which corresponds to a natural form of the body in the area of the head that is not subject, as it may be the case for the feet, to loose movements and or more or less intense.
    In addition, as illustrated in the figures, the front surface 142 of the trim structure in the area of the rear seat side box 12b is substantially rectilinear in top view, which corresponds to a front surface 142 set to substantially horizontal axis, based on the curve described above in the section having the minimum width Lmin of the passage 21.
    This form of the lateral box 12b makes it possible to form a housing of feet of relatively large dimensions, for a person lying down using said footwell, in which it is possible to move the feet and to turn without difficulty.
    Advantageously, the height of the lying plane in the bed position is close to the height hzmin so as to benefit from the maximum extension towards the front of the rest zone of the feet.
    Thus the passage 21 also widens in plan view on each side of its narrowest part, having a convergent-divergent shape with a neck of width Lmin.
    This convergent-divergent form also has the effect of naturally guiding the user of the seat when it engages in the passage 21 and to provide increased movement capacity as soon as the minimum width of said passage is crossed.
    This characteristic is observed in FIG. 4c, which schematically represents the envelope contours of the front seat 10a and the rear seat 10b in a section formed in a horizontal plane XY at height hzmin.
    This characteristic is also found on the different sections, formed in horizontal planes offset from the plane of the section of Figure 4c, Figures 4a to 4g, the width of the minimum passage in the section considered evolving, as described previously to increase below and above the plane corresponding to the minimum value of the width Lmin of the passage 21, and being always greater than said width Lmin.
    In the exemplary embodiment illustrated, the width of the minimum passage according to the height above the floor changes as shown in the following table:
    In this example, the height hzmin (plane of section 4c) of the minimum width is 330 mm above the floor.
    The above values are given by way of illustration only as a concrete example of an embodiment that provides comfort adapted to a "business" class in an aircraft, and may be modified more or less 10 mm maintaining an acceptable level of comfort if the minimum width Lmin is decreased, and slightly increased with increasing seat pitch if the minimum width Lmin is increased.
    These values may, however, be modified by those skilled in the art more or less depending on the level of comfort that he wishes to obtain or the opposite of constraints that he agrees to introduce.
    Of course the value of the minimum width Lmin of the passage 21 at the height hzmin must respect a minimum value of acceptable passage not only for reasons of comfort with respect to the user of the seat, but also to allow an emergency evacuation when standards are applicable as in most public transit vehicles, for example transport aircraft.
    There is no theoretical limit to choosing a larger value for the minimum width Lmin of the passage 21, but it should be noted that the choice of an increased minimum passage width goes against the reduction of the pitch. seats sought by the invention and, beyond a standard pass value, comfort for the user is not necessarily improved.
    Advantageously, the minimum width Lmin of the passage 21 is between 200 mm and 300 mm, the values of the passage widths for the other heights that the height hzmin being adapted to facilitate the circulation in the passage 21 as described above.
    At the level of the floor, the width Linf is advantageously equal to or greater than 300 mm for the passage of the feet and is widened with respect to the minimum width, at least in the vertical section of minimum width, preferably towards the front, that is, by the shape of the rear surface 141 of the front seat trim structure 10a.
    As shown in the exemplary embodiment illustrated in FIG. 2, the shapes of the front surfaces 141 and rear surfaces 142 can be adapted locally, for example at a connection of the floor covering structure. Such adaptations, without calling into question the principles of the invention, allow for example to adapt to the constraints of connections of the structures of the seat to the structures of the floor or to facilitate the maintenance of the areas subject to the materials that can be transported by soles of shoes.
    It will, however, be sought a minimum Linf width at the floor, for hz = 0 if the floor is taken as reference height, so that the passenger using the passage can pass his feet without the risk of getting caught or interfere. The invention thus makes it possible to optimize the space used in a cabin by a staggered arrangement of the seats which makes it possible to reduce the width necessary for arranging two rows of seats and by reducing the distance required between two seats of a single seat. row when a passage must be provided to a traffic lane.
    This configuration is advantageous in the case of an assembly arranged against a partition, for example 2 + 2 front passengers in an aircraft, or when two sets are juxtaposed, for example to form a 2 + 4 + 2 arrangement front passengers in an aircraft.
