In a motor-adjustable vehicle seat, longitudinally adjustable attachment rails (6, 7) which are connected to one another are provided in parallel guide rails (2, 3), two adjustment spindles (20, 21), whose adjustment nuts (22, 23) are permanently connected via nut holders (24, 25) to the guide rails (2, 3) being arranged parallel to the said rails (2, 3 and 6, 7). The adjustment spindles (20, 21) can be rotated by means of a motor (11) which is coupled to angular gears (14, 15) via drive shafts (18, 19), the angular gears (14, 15) themselves being in engagement with the adjustment spindles (20, 21). As a result of production faults or due to displacement or distortion during installation of the adjustable seat carrier or as a result of wear, an offset (a, b) of the contact or stop faces (53, 54 and 55, 56) can occur at the adjustment nuts (22, 23) or the housings of the angular gears (14, 15). In order to compensate this offset (a, b), elastically deformable stop elements (51, 52), for example hollow cylindrical rubber components, are provided between the contact or stop faces (53, 54 and 55, 56), the said rubber components engaging round the adjustment spindles (20, 21) and being partially compressed when the seat is retracted into its one limit position and, during this process, compensating the offset (a, b) so that the striking of the adjustment nuts (22, 23) against the gear housings takes place in a comparatively quiet and jolt-free manner for the user of the seat. <IMAGE>
