    专利说明:

    [0001] The present invention relates to a seat, in particular for a railway vehicle, and a vehicle equipped with this seat. A seat for a railway vehicle conventionally comprises a substantially horizontal seat, a backrest and a frame supporting the seat and the backrest.
    [0002] The seat or backrest is traditionally movable relative to the frame, between a so-called working position in which the backrest is substantially vertical and a reclined inclined position in which the backrest has a slope allowing a passenger to relax. In general, the angular adjustment of the backrest, which is the measurement of the angle between the bottom of the backrest and the seat, allows a progressive adjustment of the position of the backrest of the working position, in which the angular adjustment is the order of 110 to 115 ° to the rest position, wherein the angular adjustment is of the order of 120 to 125 °. To improve the comfort of the passengers, it is constant to seek to increase the angle between the bottom of the backrest and the seat when the seat is in the rest position. To do this, one solution is to increase the space between two seats in file, commonly called not between seats, to allow greater displacement of the seat forward and thus to allow a significant inclination of the folder. During this inclination, the seat moves forward, causing the bottom of the backrest to limit the intrusion of the top of the backrest in the space reserved for the passenger sitting in the seat at the rear. Patent document US20030111888 shows an example of a seat without rear intrusion. However, this solution reduces the number of seats transported by car and therefore increases the cost of transport. However, a current trend is to reduce the pitch of seats to increase the number of seats transported so as to reduce the cost of transport, while providing the passenger with improved comfort. One solution for increasing the angular adjustment without increasing the pitch between the seats is to achieve the angular adjustment by reducing the displacement of the seat forward and increasing the intrusion of the backrest in the space dedicated to the passenger sitting on the seat at the back. However, because of the back intrusion of the backrest, this solution reduces the comfort of the passenger sitting in the back seat by reducing its available space 35 and reducing access to the back seat.
    [0003] Also, the present invention aims to overcome all or part of these disadvantages by providing a rail vehicle seat having improved comfort while being of limited size to respect the seat pitch, without back intrusion of the folder.
    [0004] For this purpose, the subject of the present invention is a seat, in particular for a railway vehicle, comprising a backrest, a seat, a chassis, first connecting means connecting the backrest to the chassis and second connecting means connecting the seat to the chassis. the first and second connecting means being configured to guide respectively a movement of the backrest and the seat relative to the frame between a nominal position and an inclined position, the seat being characterized in that the backrest comprises a first part and a second part, the second part being articulated to the first part and articulated to the seat, and in that the first part comprises an intermediate portion, the second part being hinged to the first part on this intermediate portion.
    [0005] Thus, the seat according to the invention offers a kinematics allowing both improved comfort and a restriction of the seat pitch. Indeed, the articulated two-part backrest provides more comfort, because it allows to provide progressive lumbar support, by tilting the second part relative to the first part.
    [0006] In addition, the fact that the connection between the second portion and the first portion is at an intermediate portion of the first portion limits the size of the seat, and also its mass since it is no longer necessary to support this first part to have a chassis rising behind and to the top of the folder. This makes it possible to respect or even reduce the seat pitch, without prejudice to passenger comfort. Also, the fact that the seat is connected to the second part of the folder, itself linked to the first part of the folder, allows to move simultaneously, in one movement, both the seat and the backrest. This improves the ergonomics of the seat. According to a preferred embodiment, an upper end of the second part is articulated to the intermediate portion of the first part. This arrangement has the advantage of offering even more limited space. According to a preferred embodiment, the first connection means comprise a low guide unit configured to guide a lower end of the first part relative to the frame.
    [0007] Guiding the first part at its lower end limits the vertical dimensions of the seat, and also limits the mass of the frame, the latter does not need to extend all along the folder. According to a preferred embodiment, the first connecting means comprise a high guiding unit configured to guide the second part, or the intermediate portion of the first part, between the pivot connection P1 connecting the second part to the first part relative to the frame. and a lower end of the first part. The fact that the high guidance of the backrest is at the level of the connection between the second part and the first part limits both the thickness of the upper part of the backrest and the size of the seat, because it is not necessary that the frame extends to an upper end of the folder to guide it. This makes it possible to respect or even reduce the seat pitch while benefiting from improved comfort. According to a preferred embodiment, this high guiding unit comprises a slide and a guiding finger movable along the slideway, this guiding finger coinciding with the axis of rotation of the second part relative to the first part. . Thus, the high guiding unit is common to the second part and the first part of the folder. This therefore limits the number of mechanical components. This results in a more compact seat structure. For a given inter-seat distance, this implies more space, therefore comfort, for a passenger. According to a preferred embodiment, the second connecting means comprise a rear guiding unit, the rear guiding unit comprising a slide and a guiding finger movable along the slide, this guiding finger being merged with the guide. axis of rotation of the second part relative to the seat. Thus, the rear guide unit is common to the second part and the seat. Again, this limits the number of mechanical parts, so that the seat is more compact and more comfortable. According to a preferred embodiment, the second connecting means 30 comprise a forward guiding unit, this front guiding unit comprising a guiding finger remote from the guide pin of the rear guiding unit by a distance greater than or equal to half the length of the seat, preferably greater than or equal to three quarters of the length of the seat. Having a long distance between the guiding fingers of the front and rear guide units makes it possible to promote the stability and strength of the seat.
    [0008] According to a preferred embodiment, the second connecting means comprise a front guiding unit, this front guiding unit comprising a slide and a movable guiding finger along the slide, the slide of the front guiding unit being secured. of the seat.
    [0009] The fact that this slide is secured to the seat, and not the frame as the slides of other guide units, significantly improves the stability of the seat, without prejudice to the compactness of the seat. According to a preferred embodiment, the second part of the file has a convex shape.
    [0010] This convex shape provides lower cost lumbar support of the passenger's back when the seat is in the inclined position. This feature therefore improves comfort at reduced costs. Advantageously, the second part of the file comprises two lateral uprights delimiting between them a free space.
    [0011] Thus, the lateral uprights of the second part of the backrest provide lateral support allowing the passenger to rely more particularly on one side or the other of the file to rest. This characteristic therefore offers a better comfort. According to another aspect, the invention also relates to a vehicle, in particular a railway vehicle, comprising at least one seat having the aforementioned characteristics. This vehicle thus offers improved comfort in a space between two consecutive reduced seats. Other features and advantages will become apparent from the following detailed description of an embodiment of the present invention, given by way of non-limiting example, with reference to the accompanying drawings, in which: FIGS. 1 and 2 are side views of a seat according to an embodiment of the invention, respectively in a first comfort position, nominal, and in a second comfort position, inclined, FIG. 3 is a perspective view of a According to one embodiment of the invention, FIGS. 4 and 5 are side views of a part of a seat according to one embodiment of the invention, respectively in the first comfort position and in the second position of comfort, Figures 6 to 10 are perspective views of parts of a seat according to one embodiment of the invention .. Figures 1 to 3 show a seat 1 according to one embodiment of the invention . The seat 1 is intended to equip a vehicle, including a railway vehicle. It is specified that the description is made with respect to a Cartesian reference system linked to a railway vehicle, the X axis being oriented in the longitudinal direction of the vehicle, the Y axis being oriented in the transverse direction of the vehicle and the Z axis being oriented in the vertical direction of the vehicle. The orientations, directions and longitudinal, transverse, vertical, front, rear displacements are thus defined with respect to this reference frame. The seat 1 comprises a backrest 2, a seat 4 and a frame 6 that can be fixed to the floor of the vehicle. The chassis 6 is intended to remain fixed with respect to the vehicle. The frame 6 may include a foot, extending for example vertically under the seat 4, the foot allowing the seat 1 to rest on the floor of the vehicle. The seat 1 also comprises first connecting means connecting the backrest 2 to the frame 6 and second connecting means connecting the seat 4 to the frame 6. The first and second connecting means will be described in more detail below. The fact of having a connection between the backrest 2 and the frame 6, this link guiding the movement of the backrest 2 relative to the frame 6, avoids a backward intrusion of the backrest 2. Thus, the seat 1 is of the type without intrusion back. Also, the first connecting means are configured to allow displacement, for example in translation, of the backrest 2 relative to the chassis 6 without rear intrusion of the backrest 2, and the second connecting means are configured to allow movement of the backrest 2. seat 4 relative to the frame 6, for example in translation, between a nominal position and an inclined position both allowing the seat 1 to receive a seated passenger. According to the example of FIGS. 1 to 10, in the nominal position, the seat 4 is pushed towards the rear of the seat 1 and the backrest 2 is substantially straight (FIGS. 1 and 4), its upper end being at its point the upper. In inclined position, the seat 4 is pushed towards the front of the seat 1 and the backrest 2 is collapsed, its upper end being at its lowest point (Figures 2 and 5). Thus, whatever the position, nominal or inclined, the backrest 2 is prevented from protruding from a vertical plane P tangent to the rear of the seat 1, as can be seen in FIGS. 1 and 2, and this by way of intermediate of the first connecting means imposing a constraint of movement between the backrest 2 and the frame 6. Whatever the position of the backrest 2, the seat 1 remains fully contained in a space delimited by two parallel vertical planes separated by an equal distance at no seat. As illustrated in Figures 4 and 5, the backrest 2 is in two parts 8, 10 hinged, including a first portion 10 and for supporting the upper back and the head of a passenger and a second portion 8 for supporting a lumbar area of the passenger's back. This first part 10 may comprise a headrest 12. The backrest 2 also comprises a pivot link P1, with a transverse axis Y, connecting the second part 8, preferably an upper end 14 of the second part 8, and the first part 8. Part 10. Thus, the second portion 8 and the first portion 10 are rotatable relative to each other, which provides greater comfort when the backrest 2 is in the inclined position. The seat 1 comprises a pivot link P2, of transverse axis Y, this pivot connection connecting the seat 4, preferably a rear end 16 of the seat 4, and the second part 8 of the backrest 2, preferably one end. 18, the second part 8 of the backrest 2 and the seat 4 are movable in rotation relative to each other, and the displacement of the seat 4 simultaneously drives that of the backrest. 2, and vice versa. The first portion 10 of the backrest 2 comprises a lower end, an upper end 22 and an intermediate portion 24 extending between the lower end and the upper end 22. It is important to note that the first portion 10 is articulated to the second portion 8 at the intermediate portion 24, and not at the lower end of the first portion 10. In other words, the link pivot P1 connects this intermediate portion 24 of the first portion 10 to the second portion 8. This limits the size of the seat 1. This also limits the weight of the frame 6, because it does not need s 'spread high for 30 support the first part 10 of the record 2; this first portion 10 is indeed supported at the intermediate portion 24 by the second portion 8. This also facilitates the manufacture of the frame 6, in particular by injection. Due to the articulation of the backrest 2 at the intermediate portion 24, there is therefore a compact seat 1, to respect the seat pitch, or even to reduce the seat pitch, so that it allows increase the amount of seat per vehicle, without prejudice to comfort.
    [0012] The pivot link P1 connecting the intermediate portion 24 of the first portion 10 to the second portion 8 is located relative to the lower end at a distance of between one quarter and three quarters, preferably between one third and two thirds, of the distance separating the lower end and the upper end 22. According to the preferred embodiment illustrated in FIGS. 1 to 10, the pivot connection P1 is located equidistant from the lower end and from the upper end of the first part 10. In other words, the articulation between the second portion 8 and the first portion 10 of the backrest 2 is preferably located substantially in the middle of the first portion 10.
    [0013] Still in a context of compactness of the seat 1, the reduction of the mass and dimensions of the frame 6, the intermediate portion 24 of the first portion 10 is connected, by the pivot link P1, to the upper end 14 of the second portion 8 As illustrated in FIGS. 4, 5 and 6, the first connection means here comprise a low guide unit 26 and a high guide unit 28.
    [0014] The low guide unit 26 is configured to guide the lower end of the first portion 10 relative to the frame 6 when the backrest 2 and the seat 4 are moved from the nominal position to the inclined position and vice versa. In other words, the guiding of the first part 10 of the backrest 2 is advantageously carried out in its lower part, which limits the bulk.
    [0015] The low guide unit 26 may comprise a slideway 30 and a movable guide pin 32 inside this slideway 30. Preferably, the slideway 30 is integral with the frame 6 and the guide finger 32 is connected to the guide rail 32. lower end of the first portion 10 of the backrest 2. The upper guide unit 28 is configured to guide the second portion 8, preferably the upper end 14 of the second portion 8, and / or the intermediate portion 24 of the first portion 10 between the pivot connection P1 connecting the second portion 8 to the first portion 10 and the lower end of the first portion 10. The upper guide unit 28 advantageously extends up to the pivot connection P1 connecting the second part 8 and the first part 10. Thus, the whole part of the backrest 2 which extends above the axis of the pivot connection P1 connecting the second part 8 and the first part 10 is advantageously free, it is to say free linking or guiding with respect to the chassis 6. This limits the size of the seat 1, limits the mass and dimensions of the frame 6, because it is not necessary for the frame 6 to extend all the way along the backrest 2 for guide him.
    [0016] It follows from the above that the first portion 10 of the backrest 2 is advantageously guided exclusively downwards and substantially in the middle, but not beyond the joint connecting the second portion 8 and the first portion 10. As illustrated in detail on FIG. 8, the high guiding unit 28 may comprise a slideway 34 and a guiding finger 36 movable inside this slideway 34. Preferably, the slideway 34 is integral with the frame 6 and the guiding pin 36 is connected to the upper end 14 of the second portion 8 and / or to the intermediate portion 24 of the first portion 10. Preferably, as illustrated in FIG. 8, the guiding pin 36 of the high guiding unit 28 is in fact the axis of the pivot connection P1 connecting the second portion 8 and the first portion 10. Thus, the high guide unit 28 is common to the second portion 8 and the first portion 10 of the folder 2. The number of mechanical components is thus reduced: the seat 1 is more compact, which improves comfort while respecting the seat pitch. Advantageously, the intermediate portion 24 of the first portion 10 comprises an offset arm 38, visible in FIG. 8, that can extend substantially transversely to the first portion 10 and the pivot link P1 connecting the first portion 10 and the second portion 10. part 8 is formed on this arm 38 of offset.
    [0017] Thus, the backrest 2 offers more inclination, without rear intrusion. The comfort is improved without prejudice to the compactness of the seat 1, that is to say, respecting the seat pitch. According to the example of FIG. 8, the offset arm 38 may comprise a bore inside which the axis 36 of the pivot connection P1 connecting the second portion 8 and the first portion 10 extends. The seat 1 comprises here also a rear guide unit 40 configured to guide the seat 4, preferably a rear end 16 of the seat 4, and / or the second portion 8 of the backrest 2, preferably the lower end 18 of the second part 8, relative to the chassis 6. In the first case, the rear guide unit 40 belongs to the second connecting means, in the second case, the rear guide unit 40 belongs to the first connecting means. As illustrated in FIG. 7, the rear guide unit 40 may comprise a slideway 42 and a movable guide finger 44 inside this slideway 42. Preferably, the slideway 42 is integral with the frame 6 and the finger 44 guide is connected to the second part 8, in particular to the lower end 18 of the second part 8, and / or to the seat 4.
    [0018] Advantageously, the guide pin 44 of the rear guide unit 40 is the axis of the pivot connection P2 connecting the second portion 8 and the seat 4. Thus, the rear guide unit 40 is common to the second part 8 and the seat 4. Again, this limits the number of mechanical parts, so that the seat 1 is thus more compact and more comfortable. When the rear guide unit 40 connects the seat 4 only to the frame 6 and the upper guide unit 28 connects the first part 10 only to the frame 6, the second part 8 of the backrest 2 may be devoid of guiding, connection with the chassis 6. As illustrated in FIGS. 4, 5 and 9, the second connecting means comprise a front guide unit 46 configured to guide the seat 4 with respect to the frame 6. The front guide unit 46 may comprise a slide 48 and a guide finger 50 movable inside this slide 48. Preferably, the slide 48 is integral with the seat 4 and the guide pin 50 is connected to the frame 6, which allows placing the guide pin 50 as close as possible to a front end of the seat 4 in order to benefit from improved stability, without prejudice to the compactness of the seat 1. The guide finger 50 of the unit 46 of front guide and guide finger 44 of the rear guide unit 40 are advantageously distant by a distance greater than or equal to half the length of the seat 4, that is to say from the distance separating the end 52 from the end 16 rear of the seat 4, and preferably greater than or equal to three quarters of the length of the seat 4. This also improves the stability of the seat 4. 25 Note that the guide units, including low, high and rear, advantageously extend laterally, that is to say on the sides of the backrest 2 or the seat 4. The slides 30, 34, 42, 48 extend for example in the longitudinal plane XZ, and the guiding fingers 32, 36, 44, 50 for example extend substantially parallel to the transverse direction Y. Advantageously, the guides 30, 34, 42 of the low, high and rear guiding units can be arranged on an inner wall 54 of a side flange 56 of the chassis 6. In particular, 30, 34, 42 of the low guide units, high and rear, may be formed by a rib 58 projecting delimiting a groove 35 having as a bottom wall part of the inner wall 54 of the flange 56 corresponding.
    [0019] The slides 30, 34, 42, 48 may be rectilinear or curvilinear. Preferably, the slide 34 of the high guiding unit 28 and the slide 30 of the low guiding unit 26 are non-parallel: they form between them an angle other than 00 or 180 °. This makes it possible to create a more pronounced inclination of the backrest 2 with respect to the vertical in an inclined position. Likewise, always with the aim of improving the comfort of the passenger without increasing the bulk, the slide 48 of the front guide unit 46 and the slideway 42 of the rear guide unit 40 are preferentially non-parallel: they form between them an angle different from 0 ° or 180 °.
    [0020] As can be seen in FIGS. 1 to 5, the second part 8 of the backrest 2 has, seen from the seat 4, a convex shape, for example substantially curvilinear, which improves the comfort of the passenger by offering him lumbar support, but without additional component, which is advantageous in terms of cost and space.
    [0021] Furthermore, the second portion 8 of the backrest 2 preferably comprises two side uprights 60 delimiting between them a free space to provide lateral support to the passenger. The second portion 8 may also comprise a shell 70 fixed, for example welded, to the uprights 60 to support a gasket 62. Similarly, the first portion 10 may comprise two lateral uprights 72 and, if appropriate, a fixed shell 68, for example welded, to the lateral uprights 72 to support a lining. As illustrated in Figure 3, the backrest 2 may include a liner 62 having a curvature for lateral support and a central horizontal zone 64 of convex shape for lumbar support. Below this central zone 64, the lining 62 is very reduced in thickness to allow a large space in the knees with a seat pitch of at least 1. For example, the width of the backrest 2 below the central zone 64, that is to say substantially at the height of the knees of a passenger, as shown in FIG. 1, is less than or equal to 30 mm. For a question of mass and mechanical strength, the uprights 60, 72, 30 the shell 70 and the seat frame 4 may be steel, the hull 68 and the flanges 56 aluminum, while the frame 6 may include aluminum elements and plastic elements. The seat 1 may comprise a shelf mounted to rotate relative to the backrest 2 between an extended position in which the shelf is substantially horizontal to allow a passenger to place an object and a stored position in which the shelf is substantially vertical , folded against the backrest 2. Note that the seat 1 may advantageously include an actuator 66 for facilitating the movement of the seat 4 and / or the backrest 2 of the nominal position to the inclined position, and vice versa. Control means, such as a control button, may be provided to allow a passenger to control the actuator 66. In the example of Figures 1 to 10, the actuator is a gas cylinder or gas spring. Preferably, the seat 1 comprises a single actuator 66. This is sufficient because the seat 4 and the backrest 2 are connected: the movement of one simultaneously drives the movement of the other. This allows moreover to reduce the number of components, so congestion. The invention also relates to a vehicle, in particular a railway vehicle, comprising at least one seat 1 having the aforementioned characteristics.
    [0022] Due to the absence of rear intrusion, and a compact seat 1, it is possible to reduce the seat pitch, and consequently to increase the amount of seat per vehicle, without having to take place at the expense of comfort. In operation, to place the seat 1 in the inclined position, a user can engage the actuator 66, for example by pressing a button.
    [0023] The actuator 66 assists the user in moving the seat 4 forward, for example in translation. The seat 4 is guided by the slides 42, 48 relative to the frame 6. In doing so, because of the pivot connection P2 connecting the seat 4 and the second part 8, the second part 8 is driven by the seat 4 and simultaneously guided to the seat 4. Guided if necessary by the slide or slides 34, 42, the second portion 8 moves relative to the frame 6. The guides of the guide units are arranged relative to each other so that the angle between the seat 4 and the second part 8 increases, which increases the comfort for the passenger. Due to the pivot connection P1 connecting the second part 8 to the first part 10, this first part is displaced, for example e translation, with respect to the frame 6 simultaneously with the second part 8 and the seat 4. The first part here is guided by the slideways 30, 32 with respect to the frame 6. The arrangement of the slideways of the guiding units is such that the angle between the first part 10 and the vertical increases, without the upper end 22 of the first part 10 extends back beyond a plane P tangent to the rear of the seat 1, that is to say without causing a rear intrusion. Folder 2 tends to sag during this move. The second part 8 and the first part 10 articulated relative to each other offer progressive lumbar support to the passenger. To move from the inclined position to the nominal position, the user can again press a command button, so that the retracting actuator moves the seat 4 towards the rear of the seat 1, which causes, according to a reverse kinematics of that detailed above, a simultaneous movement of the second portion 8 and the first portion 10 of the backrest 2. The backrest 2 is recovering, find a higher and upright position in the inclined position. Of course, the invention is not limited to the embodiment described above, this embodiment being only an example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by the substitution of technical equivalents, without departing from the scope of protection of the invention. Thus, instead of slides and guiding fingers movable within these slides, the first and / or second connecting means may comprise parallel connecting rods connecting the frame 6 to the seat 4, or the second part 8, or the first part 10. 20
