Each rack 40A, 40B includes a connecting portion 42A, 42B, attached to the rear portion of one of the carriages 22A, 22B, extending through a ring gear sector 44A, 44B extending in a circular arc centered on an axis extending in the transverse direction of the seat. The toothed ring sector 44A, 44B comprises a free end 45A, 45B, that is to say one end that is not in contact with other parts. The sector 44A, 44B comprises a toothing 46A, 46B along its inner edge and a toothing 48A, 48B along its outer edge, preferably coaxial. By way of example, the pitch radius of the internal toothing 46A, 46B is between 50 mm and 300 mm, preferably between 80 mm and 200 mm, and the pitch radius of the external toothing 48 A, 48 B is between 60 mm. and 310 mm, preferably between 90 mm and 110 mm. The vertex angle of the internal toothing 46A, 46B and the external toothing 48A, 48B is between 10 ° and 90 °. The thickness of each rack 40A, 40B, measured in the transverse direction of the vehicle, is between 2 mm and 10 mm when the rack is made of steel and is between 5 mm and 30 mm when the rack is made of plastic. Preferably, the racks 40A, 40B are identical and the axes of the teeth 46A, 46B of two racks 40A, 40B are aligned. The racks 40A, 40B may correspond to metal parts and / or composite material. When the racks 40A, 40B and the carriages 22A, 22B are made of composite material, the rack 40A, 40B and the carriage 22A, 22B associated may correspond to a single piece.
    [0007] The device 14 comprises a toothed wheel 50A, 50B which is pivotally mounted at each end of the tube 28 around an axis extending in the transverse direction of the seat 10. Each toothed wheel 50A, 50B meshes with the external toothing 46A, 46B of one of the racks 40A, 40B.
    [0008] The device 14 comprises an actuator 52 fixed to the lateral flange 26A on the outwardly facing side of the seat 10. The device 14 further comprises pinions 54A, 54B, each pinion being mounted on a shaft 55A, 55B of which axis 5 extends in the transverse direction of the seat 10. Each pinion 54A, 54B meshes with the internal toothing 46A, 46B of the rack 40A, 40B. Each side flange 26A, 26B includes an opening 58A, 58B. The actuator 52 is adapted to rotate the shaft 55A carrying the pinion 54A through the opening 58A. The shaft 55B is pivotally mounted in the opening 58B. The actuator 52 may correspond to an electric motor or a mechanism actuated manually by the occupant of the seat. A cover 60A, 60B is attached to the side flange 26A, 26B on the inwardly facing side of the seat 10. Each cover 60A, 60B protects the gearwheel 50A, 50B and pinion 54A, 54B and includes an opening 60A, 60B receiving an end of the pinion shaft 54A, 54B in a pivotal connection. Figures 6 and 7 show the seat 10 at two operating positions, respectively when the seat 12 20 is in the position closest to the floor of the vehicle and when the seat 12 is in the furthest position from the floor. The passage between the two positions is carried out as follows. When the occupant of the seat 10 uses the actuator 52, it drives the pinion 54A in rotation. The engagement of the pinion 54A with the internal toothing 46A of the rack 40A causes relative movement between the side flange 26A to which the actuator 52 and the rack 40A are attached. The overall movement followed by the seat 12 is imposed by the rods 30A, 30B and by the racks 40A, 40B. As shown in FIG. 7, a tube 64 can connect the two links 30A, 30B to ensure that they have the same displacement at all times. The presence of the toothed wheel 50A, 50B ensures that the pinion 54A, 54B corresponding meshes permanently with the internal toothing 46A. This makes it possible to compensate for the misalignments when the pinion 54 and the actuator 52 are mounted on the flange 26A. The fact that each rack 40A, 40B is directly attached to the carriage 22A, 22B makes it possible to reduce the number of parts used for adjusting the height of the seat 12 and to simplify the method of mounting the adjustment device 14. A benefit to provide the two racks 40A and 40B is that a symmetrical transmission of the forces on each side of the seat 10 is favored. This reduces the risk of non-symmetrical deformations of the device 14 for adjusting the height of the seat 12, especially in case of shocks. An advantage of the meshing of the pinion 34 with the internal toothing 46A is that the rack 40A contributes to the protection of the pinion 34 against the external elements, in particular the seat lining 10. In the embodiment shown in FIGS. 1 to 7 , the actuator 52 is located on the right side of the seat 10 seen from the front. Alternatively, an actuator could be provided on the left side of the seat 10 seen from the front. In addition, the seat 10 has been shown with two connecting rods before 30A, 30B. Alternatively, only one of the front links 30A, 30B may be present. In addition, the seat 10 has been shown with two racks 40A, 40B. Alternatively, only the rack 40A may be present, the rack 40B may be replaced by a rear rod which may have a similar structure to the connecting rod before 30B. In the embodiment shown in Figures 1 to 7, the pinion 54A driven by the actuator 52 meshes with the internal toothing 46A of the rack 40A. Alternatively, each pinion 54A, 54B can mesh with the external toothing 48A of the rack 40A, 40B and each toothed wheel 50A, 50B can mesh with the internal toothing 46A, 46B of the rack 40A, 40B. An advantage of the meshing of the pinion 34 with the external toothing 48A is that, for the same pitch radius, the size of the rack 40A, 40B in which the pinion 34 meshes with the external toothing 48A is smaller than the Congestion of the rack 40A, 40B in which the pinion 34 meshes with the internal toothing 46A, 46B. In the embodiment shown in FIGS. 1 to 7, each carriage 22A, 22B extends substantially under the whole of the seat 12. Alternatively, each carriage 22A, 22B can be replaced by two carriages of dimensions reduced sliders adapted to slide in the same section 18A, 18B, one of the two trolleys being used for fixing the base 34A, 34B and the other trolley being used for fixing the connecting portion 42A, 42B of the rack 40A, 40B. Figure 8 is a view similar to Figure 4 of a seat 70 according to another embodiment. The seat 70 comprises all the elements of the seat 10 with the difference that each pinion 54A, 54B meshes with the external toothing 48A, 48B of the rack 40A, 40B, the pinions 54A, 54B being connected to each other. Another by a shaft 72. In addition, the internal toothing 46A, 46B of each rack 40A, 40B is not present and is replaced by a cylindrical edge 74A, 74B, and the tube 28 includes grooves 76A, 76B at the ends. each edge 74A, 74B being adapted to slide in the groove 76A, 76B associated.
