Abstract: A hinge joint which connects the back to the remainder of the seat in a motor vehicle has first and second leaves respectively provided with punched internal and spur gears. The internal gear receives the spur gear and at least one of its internal teeth meshes with two neighboring external teeth of the spur gear or vice versa. The rear sides of the internal and external teeth are formed with punched indentations to compensate for shrinkage of the top lands of such teeth as a result of punching. Each indentation resembles the frustum of a pyramid and is designed to effect the flow of material toward the top land of the respective tooth. The two leaves are coupled to each other by a shaft which defines therefor two parallel pivot axes.

Abstract: With a back rest for a vehicle seat, particularly a motor vehicle seat, in order to be able to adjust the longitudinal profile on the side facing the seat user by means of a shaping body having a rigid shape, the shaping body (8) has support surfaces (17, 18) both on the side facing the upholstery (7) and on the side opposite the upholstery (7), which can be placed selectively in defined positions of the shaping body (8) relative to an upholstery support against support surfaces (15') of a support element (4). When one support surface (17) is in contact with the support surface (15') of the support element (4), the longitudinal profile is different than when the other support surface (18) is in contact with the support surface (15').

Abstract: A one- or two-piece upholstery support (5) of a thigh support of a vehicle seat is pivotably arranged on a support device (11) which, in turn, is mounted on longitudinally running supports (7) so as to be longitudinally movable. These supports (7) extend forward from the rear section (2) of the seat portion. In this preferred arrangement, a detent mechanism (37, 23), which releasably secures the upholstery support (5) against pivoting, is provided between the upholstery support (5) and the support device (11). The support device (11) includes a releasable locking device (25-27), in order to secure the support device (11) in the desired position on the supports (7) against longitudinal movement.

Abstract: An adjusting arrangement for inclination adjustment of a backrest of a seat has two hinges adjustably connecting the backrest with a seat part at each side and having first and second hinge levers associated with the backrest and the seat part and connected with one another by a pivot axle, and a displacing and fixing device determining the position of the hinge lever relative to one another and formed as a wobble drive including an eccentric associated with the pivot axle and retained in a force-transmitting abutment on the pivot axle, wherein the pivot axle is formed as a continuous shaft which connects the hinges with one another and has end portions supporting the hinge levers, the shaft having a recess provided in each of the end portions and receiving the eccentric, and each hinge lever surrounding the eccentric received in the recess.

Abstract: In a back rest for a vehicle seat, particularly motor vehicle seats, an upholstery support includes side beams (1,2) and a yoke portion which extends from one side beam to the other in the vicinity of the upper ends of the side beams (1,2). The yoke portion is formed as a bending and kinking resistant spacer (3) which abuts the side beams (1,2) but is not connected thereto and extends rearwardly beyond the side beams (1,2) at least in the area of its end sections which abut the side beams (1,2). A lateral element (7) which engages the side beams (1,2) from behind is attached to the outwardly facing sides of both side beams (1,2) and the back side of the spacer (3) abuts the lateral element (7).

Abstract: A vehicle seat includes at least one upholstered side member, which is arranged at the side adjacent to the seat upholstery that is connected with the upholstery support of the seat so as to be pivotable about an axis running in the lateral direction of the seat and that can be fixed at least in two different pivot positions by means of a locking device. The locking device has two cooperating members spaced from the pivot axis of which one passes by the other member during a pivot movement of the side member and cooperates therewith in selected positions when the locking device is closed.

Abstract: The present invention relates to a seat for airplanes, buses and like vehicles. The seat comprises a frame, an upholstery support, and a three-piece device for locking both sides of the upholstery support in a selectable pivot position. The locking device includes a stepless adjustable-length bar in the nature of a hydraulic piston, a body for connecting the front end of the hydraulic piston to a front cross member of the seat frame, and a pivot lever for attaching the rear end of the hydraulic piston to a rear cross member of the upholstery support.

Abstract: A vehicle seat, the seat portion of which has an adjustable inclination, is supported on two concave guide rails (as viewed from the seat portion) which are supported by a seat frame and extend in the longitudinal direction of the seat portion so that the seat portion is longitudinally adjustable and can be locked in a selected position by means of a locking device. The locking device is arranged in the central section of the seat portion and includes a straight bar extending in the longitudinal direction of the seat portion. The ends of the bar are connected with the seat frame. This bar supports an adjusting member which can be adjusted steplessly in its longitudinal direction and can be secured in any position against a longitudinal movement. A coupling member is coupled with this adjusting member and is connected on its other end with the seat portion which is longitudinally adjustable on the guide rails.

Abstract: A vehicle seat, particularly for airplanes or omnibuses and the like, wherein the seat is equipped with a retractable leg support which can be extended to provide a support for the legs of the user of the vehicle. In contrast to known seats of this type, the leg rest can be securely stopped and held in any intermediate position of the leg support between the two end positions. This is accomplished by means of a cog and chain or belt strand connected with drive means and a self-arresting gearing arrangement.
