Abstract: In a locking device for a vehicle seat, particularly a motor vehicle seat with a first component group (12, 16), having at least one locking element (14) for interacting with a first seat rail (5), being pretensioned and movably borne on a second seat rail (8), and a second component group (22, 28) being movably borne relative to the first component group (12, 16) on the second seat rail (8) and acting on the first component group (12, 16) when acted on by a manually operated unlocking element (34), and control elements (20, 26) for controlling the unlocking process of the first component group (12, 16), the component groups (12, 16, 22, 28) are each rigid, and the control elements (20, 26) are arranged between the first component group (12, 16) and the second component group (22, 28).

Abstract: The invention relates to a longitudinal seat adjustment system for seats, comprising two pairs of rails (10) which are set apart from each other. Said pairs of rails each consist of two U-shaped rails, an upper rail (11) and a lower rail (12). These two rails (11, 12) can be switched to a locking position or a release position by means of at least one spring-loaded, plate-shaped locking part (21). Said locking part (21) has teeth (15) on two opposite sides, these teeth engaging in recesses (14) or openings (16) in the rails. According to the invention, the edge areas (44) of the tooth-like recesses (14) in the lower rail (12) and/or the edge areas (45) of the slit-like openings (16) in the upper rail (11) are permanently deformable. Consequently, in the locking position, the teeth (15) of the plate-shaped locking part (21) which engage in the openings (16) and recesses (14) deform the edge areas of said opening (16) or recesses (14) in the event of a considerable load, for example in an accident.

Abstract: A stop element for limiting the regulating distance of a longitudinal adjustment device for motor vehicles seats, whose seat part is fastened on sliding rails, wherein each sliding rail is longitudinally slidable in a guide rail secured on the vehicle floor and at least one sliding rail can be secured on the guide rail in selectable longitudinal positions by means of a locking device, is provided between the sliding rail and the guide rail. The stop element is formed of an impact member, having a snap-in head penetrating a penetration of the guide rail, and a locking hook, penetrating this impact member and lockingly engaging the guide rail.

Abstract: A locking device for vehicle seats, in particular motor vehicle seats, includes two mutually displaceable parts. A rail, associated to one of the parts, extends in the direction of displacement and has at least one row of snap-in holes extending longitudinally along the rail. These holes are separated from each other by web-like material sections. Ratchets, associated to the other part, can move in relation to the rail between a disengaging position and a locking position. They move perpendicularly to the direction of extension of the rail, and are controlled via an operating mechanism. When the mutually displaceable parts are in locked position, at least one of the ratchets engages in a corresponding snap-in hole. At least one retaining element prevents involuntary disengaging of the ratchet from an effective locking position. As a result, reliable locking is achieved, in particular in the event of a crash, which entails high frequency vibrational fractions.

Abstract: A longitudinal adjusting device on a motor vehicle seat having a seat back adjustable relative to the seat part and forwardly foldable after releasing an arresting device, has movable rails on which the seat is fastened. The moveable rails can slide in guide rails attached to the vehicle. One movable rail has a locking device that releasably locks the moveable rail on the guide rail. The locking device has a positioning device for returning the seat to its previous longitudinal position. The positioning device has a positioning disc with locking teeth and an arresting lever with a toothed segment engaging the locking teeth. The arresting lever can be released from the locking teeth to allow rotation of the positioning disc during longitudinal adjustment of the seat. A spring-loaded winding drum is arranged coaxially to the positioning disc and allows the seat part to slide forward by a tension member attached to the seat part or the guide rail.

Abstract: A longitudinal adjusting device for vehicle seats, whose backrest, which is adjustable in inclination positions which are selectable as the case may be, is swivelably connected with a seat part, has running rails and guide rails, wherein the seat part is fastened to the running rails. Each running rail is displaceable longitudinally in one of the guide rails fixed to the vehicle floor. A locking device secures at least one of the running rails to the respective guide rail in selectable longitudinal positions. A spring member supports at least one of the running rails at the guide rail for purposes of a forward displacement of the running rails, wherein the spring member is a spiral spring. A winding drum is rotatably supported on the running rail, wherein a first end of the spiral spring is associated with the running rail and a second end of the spiral spring is associated with the guide rail, wherein the second end of the spiral spring associated with the guide rail is held at the winding drum.
