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.

Motor vehicle seat arm rest control

In a longitudinally slidable motor car seat, the slide rail system of which comprises a guide rail and running rail, for an improved transmission of powerful forces without local overloading, the guide rail is accommodated by a channel open towards the motor car seat and shaped out of the material of the tunnel and/or of the sill. The guide rail is provided with a flange abutting the descending inner sill wall and exhibiting terminally a cranked part behind which a part connected to the motor car seat engages.

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.

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.

A locking rail supported on a fixed vehicle part for a lever pivotally connected to a seat frame of a longitudinally and vertically adjustable automobile seat. The lever receives one end of a safety belt system with a lower free end of the lever lockingly engaging the locking rail when a predetermined tensile stress on the belt strap is exceeded. The locking rail is rigidly attached to parts fixed to the vehicle such as, for example, the seat underframe and the vehicle floor. The lever is connected to the seat frame by way of a fishplate which is mounted on both sides in an articulated fashion.
