Abstract: The invention involves a gearbox, especially for adjustment devices in motor vehicles, with a plastic worm drive. The invention provides that the worm drive has an encircling, circular flat contact surface perpendicular to the worm axle and a number of removal pockets in the form of recesses that are interposed axially between contact surface and the worm axle and at the same time arranged in a level recessed to the level of contact surface, whereby an encircling bevel is formed in the transition area from level of removal pockets to the level of the circular contact surface.

Abstract: The invention concerns a gearing for an adjustment device, especially an automotive adjustment device. Included is a threaded spindle as well as a spindle nut sitting on the threaded spindle, while inside a housing of the gearing. On either side of the spindle nut, there is provided a bearing bush to mount the spindle nut inside the gearing housing, while at least one of the bearing bushes consists of flexible material and is clamped under prestressing between the gearing housing and the spindle nut.

Abstract: A gear for an adjusting device with includes a gear spindle (5) and a spindle nut (30) exhibiting an internal thread (32). The spindle nut (30) rests on the spindle (5) and the inner thread (32) of the spindle nut (30) engages with the spindle thread (27). A bearing sleeve (15), which exhibits a bearing section (19) for supporting the spindle nut (30), is provided on either side of the spindle nut (30). At least one bearing sleeve (15) has a guide section (25) for guiding the spindle nut (30) relative to thread spindle (5).

Abstract: The invention relates to a vehicle seat with a back rest having a frame (2) and a lordosis support (6), with the following additional configuration: The lordosis support (6) comprises a pressure plate (9) that is essentially bend resistant in at least the transverse direction of the seat or the Y-direction, forms a supporting surface in the lordosis region of the back rest and is arranged between two side frame parts (3) of the frame (2); there is at least one holding element (5a, 5b) that extends between the side frame parts (3) with a length-variable adjustment section (21), which runs in the Y-direction and connects to the pressure plate (9), and is affixed there at fixing points (30) arranged opposite each other; in an inoperative position, the pressure plate (9) is arranged with a horizontal clearance (11) or a clearance in the X-direction behind the fixing points (30); there is a driving device with which the length of the adjustment section can be shortened as the horizontal clearance is reduced.
