An adjusting device for a hinge mount of a motor vehicle seat has a housing part, a drive unit, a gear unit which is mounted downstream of the drive unit, is driven by the drive unit, has at least one self-locking gear and drives an output shaft, an element which can be adjusted about an axis of the hinge mount, is rotationally connected to the output shaft and can be adjusted in an angle range &#x2266;360&#xb0;, preferably &#x2266;90&#xb0; about the axis of the hinge mount, and at least one stop mechanism which delimits the swivel range of the arm in at least one swivel direction. The stop mechanism is mounted between a) the self-locking gear and the drive unit, b) the self-locking gear and the housing part and/or c) the drive unit and the housing part.

A self-locking step-by-step mechanism for an adjustment device of a vehicle seat has a clamping roller lock and a step-by-step device. The clamping roller lock a rotatable release wheel and a toothing. The step-by-step device has a) a pivotably mounted actuating lever, b) a driver pivotably mounted on the actuating lever and which has two driver regions which interact with the toothing of the release wheel, c) a drag lever which has supporting surfaces which enter into contact with the driver, and d) a spring. The spring has at least one projection. The drag lever has at least one indentation which is normally in engagement with the projection. The spring is fixed against rotating.

A clamping roller freewheel for an adjusting device in a motor vehicle includes a cylindrical outer surface, at least one roller pair, an output shaft, a clamping element which is rotationally connected to the output shaft and which has at least one clamping slope on an opposite side of the roller pair to the cylindrical outer surface, and a spacer device which is at least partially between the rollers and has elastic properties. This spacer device includes a spacer piece and a spring. When the spacer piece is in the normal position, an oblique surface bears against a roller. The spring presses the spacer piece into the normal position in which it exerts a force on at least one roller. When passing from the normal position to the retracted position, the oblique surface is moved away from the roller.

A clamping-roller freewheel for an adjustment device in a motor vehicle includes a housing, a cylindrical lateral surface that defines an axis, at least one roller, an output shaft that is central to the axis, and a clamping contour which is located on the side of the roller opposite from the cylindrical lateral surface and rotationally connected to the output shaft. The clamping contour is a double clamping contour. The roller is allocated to the double clamping contour. The double clamping contour has a left and a right clamping area. A clamping action arises due to the cooperation of the roller with the left or right clamping area, depending on the direction of rotation, and the cylindrical lateral surface.

A gear train is provided including an output shaft rotatable about an output axis, a housing rotatable relative to the shaft, a toothed washer having a circumferential first toothed surface, an eccentric that is rotatably disposed on the shaft and has an eccentric driving surface offset relative to the axis by an eccentricity, the eccentric comprising a driving region, an annular gear comprising a circumferential second toothed surface, a circumferential third toothed surface and an eccentric driven surface cooperating with the driving surface, a gearwheel comprising a circumferential fourth toothed surface, the first toothed surface of the washer and the second toothed surface of the annular gear meshing together in a first angular position and forming a first nutating gear having the eccentricity and the third toothed surface of the annular gear and the fourth toothed surface of the gearwheel meshing together in a second angular position.

An actuation device of an adjustment unit for automotive vehicle seats has a hand lever and a frame. The frame carries the hand lever and accommodates an output shaft. The hand lever adopts a central position when the actuation device is in a position of rest, and may be pivoted alternatively in the two directions of rotation against the action of an elastic means biasing it in the central position. The hand lever has a first driving region. An adjustment wheel having circumferential gear teeth is centred on the output shaft. A pivotal lever has a long hole surrounding the output shaft, has a left engagement region and a right engagement region substantially extending as a continuation of the long hole. These regions are both provided with teeth matching the gear teeth of the adjustment wheel and being disengaged from the teeth of the adjustment wheel in the position of rest of the actuation device. The pivotal lever is provided with a second driving region that is in engagement with the first driving region of the hand lever.

A locking device of a longitudinal adjustment device of a vehicle seat is provided with a catch bar with periodically arranged snap openings and snap studs that is assigned to a bottom rail of the longitudinal adjustment device and is further provided with a locking unit assigned to a seat rail of the longitudinal adjustment device. The locking device has at least two locking pins that can be inserted into the snap openings independent of one another, they can be disengaged only jointly. The locking pins are arranged in a guide member which has a pin bore for each locking pin. The snap pins are provided with a grooved region consisting of at least one individual groove. Said grooved region is located in proximity to the lower end of the corresponding pin bore when the locking pin is engaged in a snap opening.

The locking device for an adjustable vehicle seat with a snap-in bar extending parallel to an adjustment direction and having locking members and locking gaps arranged periodically. The locking device has a locking unit pertaining to said snap-in bar which is shiftable in the adjustment direction along said snap-in bar. The locking unit has more than two ratchet teeth, which:
