摘要： The invention relates to a bilateral drive for rotating in the one or the other direction of drive a drive wheel (1) which is linked with an adjusting device. Said drive comprises a drive lever (2) which can be rotated about a drive axis (10), starting from an initial position, in the one or the other direction. Said lever is linked with a coupling element for expanding a spring element (6) that is at least partially supported by the cylindrical drive surface of the drive wheel (1) and that entrains the drive wheel (1) in the peripheral direction when the drive lever (2) is moved away from the initial position, while the spring element (6) is no longer supported by the cylindrical drive surface of the drive wheel (1) and the drive wheel (1) is not entrained when the drive lever (2) is returned to the initial position. The coupling element comprises expansion cams (31, 32) that can be tilted about an axis spaced apart from the drive axis (10). The expansion cams expand the actuation lever (51, 52) which is linked with the spring element (6) in such a manner that the spring element (6) which is supported by the cylindrical drive surface of the drive wheel (1) is expanded.

摘要： The invention relates to a motor vehicle seat comprising at least one adjusting device, by means of which the position of a seat part can be adjusted against its weight and/or against the weight of a vehicle occupant sitting on the seat, and at least one spring element, which acts under preload on a kinematic chain of the at least one adjusting device in order to reduce the backlash thereof, said kinematic chain transmitting the adjusting force. According to the invention, said spring element (5) is arranged such that, on an adjustment of the seat part (10) against the weight (G), said spring element (6) is released, in order to supply the kinematic chain with spring energy, and tensioned on an adjustment of the seat part (10) in the weight (G) direction.

摘要： The invention relates to a drive which operates on both sides and which is provided for use in adjusting devices, especially for seats in motor vehicles. The inventive drive comprises a pivotally mounted drive lever (10) for, starting from an initial position, effecting a turning movement in one direction or the other as desired, a drive wheel (30) which is only turned when the drive lever (10) is moved out of the initial position, and comprises coupling elements (21a, 21b), which are arranged on the drive lever (10) and which have coupling areas (23a, 23b) for transmitting a turning moment onto the drive wheel (30). In order to transmit a turning moment, the invention provides that the coupling element (21a, 21b) can be coupled to the drive wheel (30) via at least one positive locking element (29a, 29b) and by one elastic element (51).

摘要： The invention relates to a drive acting on both sides for adjustment devices, comprising a rotationally mounted drive lever (10) for producing a rotational movement that can be selectively effected in one direction of rotation or in the other direction of rotation, a drive wheel (30) that can only be rotated when the drive lever (10) is moved from a zero point position, at least a one-piece coupling element (40) having two coupling areas (41, 41b) for transmitting a torque to the drive wheel (30), in addition to a sliding-block guide with areas for controlling the coupling element (40). The coupling element (40) can be displaced radially and is tiltably mounted in a guide (11) and coupled by both coupling areas (41a, 41b) in the zero position of the drive lever (10) to the drive wheel (30) in an elastic manner so that the non-loaded coupling area (41a, 41b) is uncoupled from the drive wheel (30) by the sliding-block guide when the drive lever (10) moves from the zero point position and remains uncoupled when the drive lever (10) moves in the opposite direction.

摘要： The present invention relates to a two-directional manual drive that produces a rotational movement, starting from the neutral position of a drive lever (1) that can pivot around a drive axis (20), whereby said rotational movement can occur in a selective manner in one of two rotational directions. A driven element (4) pertaining to said drive comprises a driving surface (40) on which bearing surfaces (51; 51'; 61, 61') of coupling elements are placed in non-positive fit when the drive lever (1) is rotated out of a neutral position, displacing the driven element (4) in the direction of the periphery. When the drive lever (1) is returned to a neutral position, the coupling elements (5, 6) are released from a position of non-positive fit with respect to the cylindrical driving surface (40) and the driven element (4) is no longer displaced.

摘要： The invention relates to an adjustment device for producing a rotational movement that comprises an output element (3) that can be adjusted at an angle by actuating a drive element (2). The adjustment device further comprises a load moment lock (1) interposed between the drive and the output element (2, 3) that frictionally blocks a rotational movement initiated at the output element side and that transmits a rotational movement initiated at the drive element side to the output element (3). Said load moment lock (1) further comprises locking elements (4, 4') that are disposed in a cylindrical adjustment housing (10). Upon the effect of a play-compensating device (5) that is at least partially interposed between opposite adjusting surfaces (41, 41') of the locking elements (4, 4') and that compensates the rotational angle play between the drive element (2), the output element (3) and the load moment lock (1), the clamping surfaces (43, 43', 43'', 43''') are forced apart with such a force that they rest against the adjustment housing (10) with a predetermined pre-load. The adjustment device is provided with a play-compensating device (5) that for both directions of rotation radially forces apart the locking elements (4, 4') that are disposed in one plane of the load moment lock (1) in a direction perpendicular to the axis of the load moment lock (1).
