Abstract: A motor vehicle seat system, control arrangement, actuating arrangement, and process are used to control a lumbar support device of a motor vehicle seat. The lumbar adjustment device has a first drive for adjustment in a first adjustment direction and a second drive for adjustment in a second adjustment direction. The adjustment directions differ from each other. A first adjustment position is ascertained in the first adjustment direction and the drive movement of the second drive is controlled as a function of at least one of the first adjustment position and the temporal change in the first adjustment position.

Abstract: A support element for upholstering on a vehicle seat, in particular for the backrest upholstery, with a base region of large area, for supporting the upholstery and an edge surrounding the base region. At least two separate adjacent support regions are provided along the edge of the base region, projecting from the edge.

Abstract: A backrest for a vehicle seat with a backrest frame including an arching element, running in a planar manner on the backrest frame with the upper and lower end sections thereof, in the backrest longitudinal direction, each fixed to the backrest, or to a component arranged on the backrest and an adjuster device with which the arching of the arching element may be adjusted in a middle region between the both end sections thereof. At least one limiting element is provided on the backrest frame with one end connected to the middle region of the arching element in order to limit the extent of the arching of the arching element.

Abstract: The invention relates to a support element for upholstering on a vehicle seat, in particular for the backrest upholstery, with a base region of large area, for supporting the upholstery and an edge surrounding the base region. According to the invention, at least two separate adjacent support regions (41, 42, 43, 43′, 43″, 44, 44′) are provided along the edge (R1, R2, R3, R4) of the base region (40), projecting from said edge (R1, R2, R3, R4).

Abstract: A drive acting on both sides produces a rotary movement, more particularly a rotary movement for a manual height or incline adjustment of a vehicle seat. The drive lever is coupled to locking means which can be brought into engagement with teeth mounted on the circumference of a drive wheel. The locking means have a one-piece tilt element which tilts to and fro between two end positions in dependence on the relevant drive direction wherein in each end position a locking of the tilt element takes place with the teeth of the drive wheel. The invention provides a drive acting on both sides to produce a rotary movement which has a small number of individual parts, is simple to fit and is characterized by a compact structure.

Abstract: An assembly for transmitting rotational movements and for damping torsional vibration and including a damper housing, a connection section located radially inward of the damper housing for attaching the assembly to a to-be-damped part, with the connection section being formed integrally with the housing as a one-piece part, a cover for sealingly closing the housing and a damping weight located in the working chamber which is formed in the housing, in a viscose medium filling the working chamber, with the assembly being formed as a camshaft gear, and with the radial outer circumference of the housing being formed as a camshaft gear toothing.

Abstract: A manual drive for producing rotary movement in both clockwise and counterclockwise directions includes a drive lever which has a neutral position from which it can move into a first or second rotary direction. Attached to the drive lever are a pair of detent elements, one controlling clockwise rotation of the drive wheel and the other controlling counter-clockwise rotation. The detent elements have teething elements on a free end for engagement with a drive wheel which has counter teething about its circumference. The detent elements engage the drive wheel in the neutral position. The detent elements slide in a slide guide which lifts one of the detent elements out of engagement with the drive wheel when the drive lever moves in the opposite rotary direction. Springs located on either side of the slide guide lift the detent element on the drive side out of engagement with the drive wheel as the drive lever returns to the neutral position.

Abstract: An arrangement for locking an entrainment member for a safety belt at a cassette, in which the entrainment member is adjustable along a guide profile by a pressure-resistant cable; an adjustable locking member engaging the entrainment member is thereby supported in the cassette, which is constructed tubularly-shaped and in one piece; an insert member is detachably secured in the cassette, which consists in particular of plastic material--preferably of a polyacetyl--or of a die-cast metal--preferably of aluminum--and which form-lockingly surrounds the free end of the guide profile.

Abstract: An installation in a passive safety belt actuating mechanism for the displacement of an entrainment member for a safety belt and of an unlocking element for unlocking the entrainment member from a locking mechanism, along a guide profile by means of an elongated flexible member extending in a guide profile, on which the entrainment member is secured for limited longitudinal displacement while the unlocking element is non-displaceably secured thereon; the elongated flexible member consists of a cable rigid in tension and compression with a plastic sleeve which is removed in the longitudinal displacement section of the entrainment member and in a fastening area of the unlocking element adjoining the same.

Abstract: A device for passive actuation of a safety belt includes a motor-driven force transmission member. An engaging member for the safety belt can be connected to the force transmission member by a manually releasable pin member. The force transmission member moves the engaging member and with it the safety belt into a locked position. The locked position can be released automatically or manually. The engaging member can be moved manually along the force transmission member when the driving connection is released.

Abstract: A device for passive actuation of a safety belt includes an elongated force transmission member with an engaging member secured to the transmission member so that a certain amount of play is present in the elongated direction between the transmission member and the engaging member. A locking device is arranged to receive and secure the engaging member in the locked position. A release member is secured to the force transmission member so that it moves with the transmission member while the transmission member moves relative to the engaging member whereby the release member can contact and displace the locking device out of locking contact with the engaging member. With the engaging member released from the locked position when the certain amount of play is traversed by the force transmission member, the transmission member carries the engaging member along with it.
