The passenger seats arranged in the aircraft are commonly equipped with electric actuators for moving different movable elements of the seat relative to each other.

'apparatus.
    [0003] But the inertia of the actuators connecting the various elements of the seat is not always sufficient to meet these resistance constraints in case of shock. In addition, there are significant risks of breaking the reduction chains of the actuators. Thus, it is known to immobilize certain parts of the seat relative to each other using locks during critical phases of the flight of the aircraft. These latches are constituted for example by the movable core of an electromagnet whose winding is carried by a movable part of the seat and whose movable core is movable between a retracted position and an extended position for which it is engaged in the fixed part of the seat. seat, thus ensuring a positive mechanical locking of the movement of the two seat parts relative to each other. However, the use of these locks weighs down the seat and complicates the steering. In addition, it happens that, given the manufacturing tolerances of the seat and actuators, and possible involuntary actions of the passenger on the seat, some locks are not aligned with their respective locks, which prevents the movement of said locks to their seats. exit positions.

    [0005] The seat 10 shown in Figure 1 comprises a frame 11, and a seat 12 and a backrest 14 mounted movable relative to the frame 11. It also comprises two racks 16 fixed to the floor of the cabin and along which the frame 11 is mounted slidably via a base 18. In particular, the base 18 comprises two wheels 20 each geared on one of the racks 16. Said wheels 20 are adapted to move relative to the racks 16 together with the frame 11. They form with the racks 16 means for moving the seat 10 relative to the floor of the cabin. The wheels 20 are mounted at the axial ends of a transmission shaft 22, so as to frame said shaft 22. They are integral with the transmission shaft 22.
    [0006] The transmission shaft 22 is rotatably mounted about its axis relative to the frame 11. An actuator 30 is connected to the base 18 to move the base 18 along the length of the racks 16. The actuator 30 is connected to a central control unit 32, itself connected to a keyboard 34 allowing the passenger sitting on the seat 10 to move the latter by controlling the actuator 30. In particular, the actuator 30 is adapted to drive the wheels 20 into position. rotation around their axes. For this purpose, the actuator 30 comprises, with reference to FIG. 2, a cover 40, integral with the frame 11, a motor 42, an output shaft 44, and a kinematic chain 46 for driving the drive shaft. output 44 by the motor 42.
    [0007] The output shaft 44 is constituted by the transmission shaft 22. The cover 40 is made of a relatively deformable material, for example aluminum. The motor 42 is an electric motor. It comprises, in known manner, a rotor (not shown) and a stator (not shown) housed in a housing 48 integral with the cover 40, and an output shaft 50 integral with the rotor. Preferably, it also comprises a current-canceling brake adapted to immobilize the rotor relative to the stator when the motor 42 is not supplied with electric current. The drivetrain 46 comprises a reduction chain 52 adapted to kinematically link the transmission shaft 22 to the output shaft 50 so that the speed of rotation of the transmission shaft 22 about its axis is less than the speed. of rotation of the output shaft 50 about its axis. The reduction chain 52 comprises a plurality of reduction stages 54, 56. Each reduction stage 54, 56 comprises a plurality of gear elements 60, 62, 64, 66.
    [0008] The gear elements of the first reduction stage 54 comprise an input pinion 60, rotationally integral with the output shaft 50, and a transmission pinion 62 on which the input pinion 60 is engaged. transmission gear 62 is rotatably mounted about its axis on the cover 40, is oriented substantially parallel to the input gear 60, and has a number of teeth greater than that of the input gear 60.
    [0009] The gear elements of the last reduction stage 56 comprise an output gear 64, coaxial with the transmission shaft 22, and an intermediate gear 66 on which is engaged the output gear 64. This intermediate gear 66 is mounted mobile in rotation about its axis on the cover 40, is oriented substantially parallel to the output gear 64, and has a number of teeth less than that of the output gear 64. In the example shown, the intermediate gear 66 is secured in rotation of the transmission pinion 62. In a variant, at least one intermediate reduction stage is interposed between the transmission pinion 62 and the intermediate pinion 66, so as to cinematically link these two pinions 62, 66 so that they rotate jointly around of their respective axes. The output gear 64 is thus kinematically connected to the rotor of the motor 42 so that the rotor and said output gear 64 rotate jointly about their respective axes of rotation.
    [0010] Each gear element 60, 62, 64, 66 is formed of a relatively rigid material, for example steel, preferably nitrided steel. With reference to FIG. 3, the kinematic chain 46 also comprises an upstream element 70, kinematically connected to the rotor of the motor 42 so that the rotor and said upstream element 70 rotate jointly around their respective axes of rotation, a downstream element 72, kinematically connected to the transmission shaft 22 so that the transmission shaft 22 and said downstream element 72 rotate jointly about their respective axes of rotation, and a device 74 for coupling the upstream element 70 to the element downstream 72. Each of the upstream and downstream elements 70 70 is rotatably mounted relative to the cover 40 about an axis of rotation of said element 70, 72. The axes of rotation of the upstream elements 70 and downstream 72 are coaxial one to the other. In particular, said axes are also coaxial with the transmission shaft 22. The upstream element 70 comprises a body 80 and two lugs 82 projecting axially from the body 80, towards the downstream element 72. The body 80 is constituted by the output gear 64. The two lugs 82 are arranged symmetrically with respect to each other relative to the axis of rotation of the upstream element 70. As a variant, the upstream element 70 comprises at least three pins 82 angularly distributed regularly around the axis of rotation of the upstream element 70, that is to say angularly distributed about the axis of rotation so that for each pair of pins 82 consecutive, the angle between said lugs 82 is equal to the angle between the lugs 82 of each other pair of lugs 82 consecutive.
    [0011] The upstream element 70 is rotatable about its axis relative to the transmission shaft 22. The upstream element 70 is preferably monobloc. It is made of a relatively rigid material, for example steel, preferably nitrided steel.
    [0012] The downstream element 72 is integral in rotation about its axis relative to the transmission shaft 22. The downstream element 72 is invariant by rotation of a predetermined angle around its axis of rotation. In the example shown, said predetermined angle is equal to 180 °. With reference to FIG. 4, the downstream element 72 is contained in an outer peripheral envelope 84 extending around the axis of rotation of the downstream element 72 and along the downstream element 72. This outer peripheral envelope 84 comprises sectors of revolution cylinders 86 all having the same radius. Each cylinder sector 86 has in particular an axis substantially parallel to the axis of rotation of the downstream element 72 and slightly offset relative to said axis of rotation. By "slightly shifted", it is understood that the distance from the axis of each cylinder sector 86 to the axis of rotation of the downstream element 72 is less than 1 mm, preferably between 0.3 and 0.7 mm. These sectors of cylinders 86 are preferably, as shown, connected to each other by plane portions 88 oriented parallel to the axis of rotation of the downstream element 72, each flat portion 88 extending between two consecutive cylindrical sectors 86 , so that the outer peripheral envelope is formed by alternating sectors of cylinders 86 and flat portions 88. In particular, in the example shown, the number of roll sectors 86 is equal to four, the number of portions planes 88 is equal to four, and each planar portion 88 is perpendicular to two other planar portions 88. Returning to FIG. 3, the downstream element 72 comprises two large opposite faces 90, 92, each extending substantially perpendicular to the axis of rotation of the downstream element 72. A first major face 90 is oriented towards the upstream element 70, and the second major face 92 is oriented opposite the element am have 70.
    [0013] Each large face 90, 92 is bordered by the envelope 84. The downstream element 72 has, for each lug 82 of the upstream element 70, a cavity 94 for receiving said lug 82. Said cavity 94 opens into the first large In the example shown, it also opens into the envelope 84, in particular in a flat portion 88 of the envelope 84.
    [0014] In the example shown, a bottom wall 96 closes the cavity 94 on the side of the second large face 92.
    [0015] The cavity 94 has an angular width greater than the angular width of the lug 82 that it receives. The pin 82 can thus move angularly in the cavity 94. The downstream element 72 also has housings 98 for coupling members 100 of the coupling device 74.
    [0016] Referring to Figure 4, each housing 98 opens into the envelope 84, in particular in a cylinder sector 86 of the casing 84. In the example shown (Figure 3), each housing 98 also opens into the first large face 90, and is closed by the bottom wall 96 on the side of the second large face 92. Each housing 98 flares radially outwardly of the downstream element 72. In other words, each housing 98 s as it moves away from the axis of rotation of the downstream element 72. In particular, each housing 98 is angularly bordered by two faces 102 of contact against the coupling member 100 housed in said housing 98, said faces 102 joining into a bottom 104 of the housing 98, and diverging from each other from said bottom 104 to the casing 84. Each face 102 is particularly flat. In the example shown, the faces 102 are oriented substantially perpendicular to each other. Each housing 98 has substantially the shape of a revolution cylinder sector.
    [0017] Each cavity 94 is angularly framed by two housings 98. The lug 82 received therein is thus angularly framed by the coupling members 100 housed in said housings 98. Each cavity 94 is separated from each of the housings 98 flanking it by a wall 106 of the downstream element 72.
    [0018] A through orifice 108 extends through the wall 106. It opens into the cavity 94 and the housing 98 separated from the cavity 94 by said wall 106. The axis of the orifice 108 is oriented towards the portion of the envelope 84 where the housing 98 opens. In the example shown, the housings 98 are four in number, each housing 98 opening into a cylinder sector 86 proper to the envelope 84. Two of the housings 98 angularly frame one cavities 94, and the other two housings 98 angularly frame the other cavity 94. The downstream element 72 is preferably monobloc. It is preferably a relatively deformable material, for example aluminum. Alternatively, the downstream element 72 is made of a relatively rigid material, for example steel, to withstand the stresses it undergoes.
    [0019] The cover 40 has an annular support surface 110 extending around the downstream element 72. Said bearing surface 110 is centered on the axis of rotation of the downstream element 72, and has a radius substantially equal to radius of the cylinder sectors 86 of the casing 84.
    [0020] The coupling members 100 are equal in number to the number of housings 98. In the example shown, they are therefore four in number. The coupling members 100 are angularly distributed about the axis of rotation of the upstream and downstream elements 70 and 72. Each coupling member 100 comprises a body 112 having a shape substantially complementary to that of the housing 98 in which it is received. and a finger 114 projecting from the body 112. The body 112 is housed at least partly in said housing 98. The finger 114 extends through the through hole 108 connecting said housing 98 to the cavity 94 that it partially frames. In particular, the finger 114 extends into the cavity 94.
    [0021] The finger 114 has a connection end 116 to the body 112, and a free end 118 opposite to the connecting end 116. The free end 118 forms a bearing face 120 against the lug 82 received in the cavity 94. The body 112 has a bearing surface 122 against the downstream element 72. Said bearing surface 122 matches the walls 96, 106 of the housing 98.
    [0022] The body 112 also has a bearing surface 124 against the bearing surface 110 of the cap 40. Said bearing surface 124 has the shape of a cylinder sector of revolution having a radius of curvature substantially equal to the radius of the surface The bearing surface 124 is in particular knurled, so as to increase the frictional forces between the bearing surface 124 and the bearing surface 110 when these two surfaces 110, 124 are in contact with each other. one with the other. Preferably, the bearing surface 124 is knurled so as to form axial grooves (not shown) on the bearing surface 124. The material of each coupling member 100 is typically of a relatively rigid material, for example steel. Each coupling member 100 is force-fitted on the downstream element 72, in a first position away from the bearing surface 100 of the cap 40, as shown in FIG. 4. By "force fitted", it is understood that the finger 114 of each coupling member 100 is engaged in the corresponding through hole 108 so that the frictional forces between the finger 114 and the through hole 108 are sufficient to hold the coupling member 100 in place. its first position under the normal conditions of use of the actuator 30. Each coupling member 100 is for example engaged on the downstream element 72 in said first position. When a coupling member 100 is in the first position, its bearing surface 124 is flush with the casing 84.
    [0023] Preferably, the lengths of the fingers 114 are chosen so that, when the two coupling members 100 flanking the same lug 82 are in first position, the bearing surfaces 120 of the two coupling members 100 rest against said lug 82 When each coupling member 100 is in its first position, the coupling device 74 is in a first transmission configuration of the entire torque exerted by one of the upstream and downstream elements 70 on the device. coupling 74 to the other of the upstream and downstream elements 70 70. Each coupling member 100 is nevertheless movable in a second position bearing against the bearing surface 100 of the cover 40, as shown in Figure 5, when the torque transferred to the coupling members 100 through the contact surfaces 102 is greater than or equal to a threshold torque. This threshold torque is the torque beyond which the force exerted by each lug 82 on the coupling member 100 against which it presses is greater than the friction forces between the finger 114 of the coupling member 100 and the corresponding through hole 108. This threshold torque is predetermined. The diameters of the fingers 114 of the coupling members 100 and the through holes 108 of the downstream element 72 are dimensioned so as to obtain this predetermined threshold torque. The threshold torque is between the static resistance torque and the breaking torque of the reduction chain 52.
    [0024] The breaking torque of the reduction chain 52 is the torque at which a gear element of the gearing chain 52 breaks, so that there is no longer any transmission of torque between the upstream and downstream ends of the chain. The static resistance torque of the reduction chain 52 is the torque from which at least one gear element of the reduction chain 52 deforms, the torque continuing to be transmitted from one end of the chain. of gearing 52 to the other. The static resistance torque is typically equal to about 80% of the breaking torque. When a coupling member 100 is in its second position, it projects out of the casing 84 and its bearing surface 124 rests the bearing surface 110 of the cover 40.
    [0025] When at least one of the members 100 is in its second position, the coupling device 74 is in a second configuration bypassing a part of the torque exerted by one of the upstream elements 70 and downstream 72 on the device. coupling 74 to the hood 40.
    [0026] The tilting of the coupling device 74 from its first to its second configuration occurs as described below. The torque of the downstream element 72 is normally transmitted to the upstream element 70 as follows: the torque is transferred to the coupling members 100 via the contact surfaces 102, and is redistributed to the upstream member through the support surfaces 120. In return for the force exerted by the coupling members 100 on the lugs 82 to transmit the torque to the upstream element 70, each lug 82 exerts a reaction force on the surface support 120 of one of the coupling members 100 which surround it. This reaction force is oriented parallel to the axis of the through orifice 108 connecting the cavity 94 receiving the lug 82 to the housing 98 of said coupling member. The reaction force is thus directed towards the portion of the casing 84 into which the housing 98 opens, and consequently tends to push the coupling member 100 out of its housing 98. The friction forces between the downstream element 72 and the coupling member 100, however, oppose the latter to leave its housing 98.
    [0027] When the torque transmitted by the coupling device 74 to the upstream element 70 reaches the predetermined threshold torque, the reaction force exerted by the lug 82 exceeds the frictional forces, so that the coupling member 100 is pushed out of its housing 98 to come into abutment against the bearing surface 110 of the cover 40. Simultaneously, the downstream element 72 rotates about its axis relative to the upstream element 70. From now on, only a limited torque continues to be transferred to the upstream element 70, the rest of the torque being transferred to the cover 40 via the bearing surfaces 110 and 124. It will be noted that the tilting of the coupling device 74 from its first to its second configuration is passively, so that one can qualify the coupling device 74 of passive device. When the coupling device 74 is in its second configuration, it can not return to the first configuration. The actuator 30 is then unusable. Thanks to the invention described above, the locking of the seat 10 is simple. Indeed, as soon as the actuator 30 is stopped, any movement of the wheels 20 is impossible: the motor current brake 42 prevents rotation of the rotor at a standstill, and therefore of the parts, whose wheels 20 , which are kinematically related to him. In addition, the seat lock 10 is reliable. Indeed, in the case where the torque exerted on the wheels 20 is too large to be supported by the reduction chain 52, this torque is partly transmitted to the cover 40 of the actuator 30. This makes it possible to avoid the breakage of the reduction chain 52, which, by uncoupling the wheels 20 of the motor 42, would release the rotation of the wheels 20. Finally, the seat 10 is only slightly increased by the actuator 30 relative to a conventional actuator.
