Abstract: The present invention teaches a wobble-hinged metal fitting suitable for adjustable motor vehicle seats, and more particularly, for back seat gears. The fitting includes two hinged brackets connected together by an eccentric, a carrier and shaft running therethrough. Each bracket contains an internal gear and an external gear associated with the internal gear. The eccentric is positioned next to one of the gears and is turnably connected to the shaft. The eccentric includes means for compensating play in the seat which consist of an eccentric part having a receiving inlet, at least one rolling body, at least two jamming planes and at least one spring. The spring is positioned such that it pressures the rolling body to come in contact with the jamming plane on one side and the gear on the other side. The carrier is positioned such that when the rolling body is in a locked position, an initial turning movement of the shaft results in the release of the locked rolling body before the eccentric starts to move.

A memory device serves to find the previously engaged position of the locking mechanism.

Abstract: A longitudinal guide for a seat sliding device for vehicle seats includes two elongated tracks that slide relative to each other. A guide is arranged between the tracks, there being at least two guides when viewed from the profile of the longitudinal guide, of which at least one is constructed using roller bodies. One track embraces the other track. The tracks are interconnected so that they will not separate. The tracks are positioned in an adjoined, preloaded manner. The tracks are manufactured of steel sheet containing at least 0.35% carbon content and are heat treated after they are complete.

Abstract: 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.
