The invention relates to a vehicle seat with a back rest having a frame () and a lordosis support (), with the following additional configuration: The lordosis support () comprises a pressure plate () 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 () of the frame (); there is at least one holding element () that extends between the side frame parts () with a length-variable adjustment section (), which runs in the Y-direction and connects to the pressure plate (), and is affixed there at fixing points () arranged opposite each other; in an inoperative position, the pressure plate () is arranged with a horizontal clearance () or a clearance in the X-direction behind the fixing points (); there is a driving device with which the length of the adjustment section can be shortened as the horizontal clearance is reduced.

Vehicle seat with lordosis support

A plastic slip clutch for an adjustable drive in an automobile includes a hub () which exhibits an inner profile (), and a shaft () which exhibits an outer profile (). For the purpose of transmitting torque, the shaft with the outer profile is introduced into the inner profile of the hub in form-fitting and force-fitting fashion. The inner profile () of the hub () exhibits plastic elements () for the transmission of force, such that the plastic elements () become elastically deformed under the effect of a force exceeding a given threshold force and thereby permit the outer profile () of the shaft () to slip through inside of the hub ().

Plastic slip clutch

The invention relates to a gear for adjusting two parts () that can be displaced in relation to each other, particularly vehicle parts of a seat adjustment device, of a window lifter or of a sliding roof, wherein the first one of the parts () comprises a non-rotatable spindle () or a fixed toothed rack. The gear comprises a worm wheel (), with a spindle nut () non-rotatable thereto for driving the spindle () or a worm non-rotatable thereto for driving the toothed rack, a drivable worm () for transmitting a driving force to the worm wheel () and a gear housing (), which accommodates and supports the worm () and the worm wheel () and which can be non-rotatably connected to the second one of the parts () in the displacement direction thereof, the gear housing () being formed by a single-piece body with a worm bearing () and a worm wheel bearing ().

Gear and vehicle seat comprising such a gear

The invention relates to a gearing mechanism for the adjustment of two reciprocally adjustable parts (), especially vehicle parts of a seat adjustment device, a window lifter or a sunroof, wherein the first of the parts () has a nonrotating spindle () or a fixed tooth rack. The gearing mechanism is formed with a wormwheel (), which has a spindle nut () non-rotatingly connected thereto in order to drive the spindle () or a worm non-rotatingly connected thereto in order to drive the tooth rack, with a worm () that can be driven so as to transfer a driving force to the wormwheel (), and with a gear housing (), which houses the worm () and wormwheel () in a supporting manner, and which can be connected immovably with the second of the parts () in its adjusting direction, wherein the gear housing () is formed of a single-piece body with a worm support () and a wormwheel support ().
