The self-locking revolute joint which can be step by step adjustable to an angle by means of pumping movements of an activation lever is particularly suitable for adjustment of seat height or backrest inclination of vehicle seats. It has a mount in which a bearing shaft is journalled. Further, it has a locking disk with notches arranged at equal angular intervals and with a torsion-proof connection with the bearing shaft; further a locking element which is preferably journalled with turning capability at the mount, also having a locking tooth confunctioning with the notches and being elastically prestressed in the engagement direction of this locking tooth and having a total of two control profiles, each one of which has a release profile and an unblocking indentation, the distance between which corresponds to the angular intervals between the notches, and confunctioning with carriers, which can be adjusted by means of the activating lever. Thereby, a return spring is assigned to the activation lever, prestressing the latter into the central position.The activation lever has a rigid connection with an activation plate, which is journalled to turn freely with the bearing shaft. On the activation plate, around a linkage axle, a release segment is linked so that it can be freely turned, having two carriers arranged symmetrically to the line connecting the linkage axle and the axis of the bearing shaft, being prestressed by means of a return spring into a neutral position, in which both carriers are disengaged from the notches and these carriers are arranged so that after a turning away from the neutral position, one of the carriers engages in one notch, while the other impacts on the adjacent release profile of the locking element and unlocks it.

The self-locking revolute joint can be adjusted at angles by turning an activation lever back and forth. It has a mount in which a bearing shaft rests rotatably in bearings, and supports an adjustment wheel which is provided with tooth profiles. The activation lever can be turned in both rotational directions around a turning axle resting in bearings in the mount; it has two swing-out carriers which do not engage with the adjustment wheel when the activation lever is in its central position; when the activation lever is turned, one of them engages with an adjacent tooth profile of the adjustment wheel and brings it to turn. Further, two locking arms rest rotatably in bearings at the mount and lock and adjustment wheel when the activation lever is in its central position. Each one of two radial cams arranged on the activation arm confunctions with a locking arm, via a release arm. When the activation lever is turned out of the central position, one radial cam brings the related release arm along and thus disengages the locking arm in the momentary drive direction.

A seatbelt lock is mounted to be movable as little as possible relative to the seat surface when the seat surface is adjusted in height or inclination. The seat has a longitudinal guide 20, 22, a device 24 for adjustment of height or inclination and a belt lock attachment 32. The lower end of the belt lock attachment 32 is affixed to the seat rail 22 of the longitudinal guide and carries a belt lock 34 at its upper end. The belt lock attachment has a lower part 38 linked to the seat rail and an upper part 40 linked to the seat carrier 26, the upper part being connected with the belt lock. One of these parts 38, 40 can move freely in a longitudinal guide formed by the other part. One part has at least one locking projection 60; and the other part has locking devices 46 interacting with the projection. By means of a safety piece 50, the two parts are held in a normal position permitting movement. When extreme forces induced during an accident act on the belt, the safety piece is overridden, whereby the locking projection engages in the locking device and removed of the upper part from the lower part is precluded.

A child seat for a motor vehicle is adjustable between a lower retracted state at the normal seat height of the motor vehicle seat, and an unfolded position in which the child seat stands out from the normal seat height for occupation by a child. A frame and a supporting structure are connected and hinge-jointed to each other by front and rear parallelogram arms. At least one diagonal locking brace is hinged on one side to one of the frame, the supporting structure and one of the parallelogram arms, and on an other side is guided by a tranverse part in a longitudinal guide. A locking segment has at least one holding notch to accommodate the transverse part, with flanks extending transversely to the longitudinal guide and a handle for releasing the tranverse part from the holding notch. The handle extends over a region of a front surface of the child seat.

A seat unit can be screwed automatically to the body platform at four fixing points without the need to alter the seat setting during screwing and has a sufficiently rigid connection, in particular a sufficiently firm connection for seat belts which are fixed to the seat, to the body platform. The fixing regions are provided in the floor rail itself, in particular in each case at a distance from the free ends of the latter and in a profile region, extending essentially parallel to the body platform, of the floor rail. These regions are joined directly to a steep wall and, with the latter, in each case form a ramp, and are oriented such that they enclose as small an angle as possible with the floor rail, although this angle is kept sufficiently large that, in an installation setting of the seat unit, the axes of the holes extend in front of the front side of the seat and behind the rear side of the seat with a clearance of a few centimeters, which makes possible the use of a screwdriver unit.

In a motor car seat with a variable-angle backrest and having an arm support retained on the frame of the backrest which is foldable down from an essentially vertical erect non-use position in line with the backrest into a lower substantially horizontal use position. While in the use position of the arm support, the backrest maintains its alignment at least during the changing of the backrest during normal driver seat back inclination adjustment, in order to prevent the arm support from striking operating parts of the vehicle; and wherein, when the backrest is folded forwards such as to allow a passenger to exit from a rear seat, the arm support is guided to maintain its position substantially horizontal and above the shift lever arranged on the central console.

An apparatus is provided for adjusting a vehicle seat having a movable support member. The apparatus includes a first frame member and a second frame member pivotably articulated to the first frame member. A backrest is desirably mounted on the second frame member. First and second driven gears are rotatably mounted on the first frame member. The apparatus further includes a first transmission system for pivoting the second frame member in relation to the first frame member to change the inclination of the second frame member and a second transmission system for changing the position of the movable support member in relation to the second frame member. The first transmission system is activated in response to rotation of the first driven gear and the second transmission system is activated in response to rotation of the second driven year. A control element is provided for selectively engaging either the first driven gear to activate the first transmission system or the second driven gear to activate the second transmission system. In operation, the control element is selectively movable by an operator to its first position to permit the operator to change the inclination of the second frame member or to its second position to permit the operator to change the position of the movable support member.
