Abstract: A vehicle seat depth adjuster (1) includes a base plate (2) connectable to a seat structure (17); a detent unit (8); a carrier plate (3) moveably arranged above the base plate; a locking unit (4) detachably engaging the detent unit; and a drive unit (11) moving the carrier plate. The carrier plate is fixed in relation to the base plate in an engaged position of the locking unit and is moveable, between a retracted position and an extended position in a released position of the locking unit by the drive unit. The detent unit is arranged on the upper side (2.5) of the base plate, which faces the carrier plate, and includes receiving elements (8.1) staggered in the direction (L) of movement. The locking unit includes an unlocking lever (5) with at least one locking tooth (5.1) that engages in one of the detent receiving elements in the engaged position.

Abstract: A seat underframe for motor vehicle seats, with two pairs of rails arranged at a distance from each other and each having a seat rail and a floor rail, a seat carrier, in each case two pivoting arms which are connected at one end in an articulated manner to the seat carrier and at the other end in an articulated manner to the seat rails and fix the maximum distance between the seat carrier and the seat rails, and a drive unit adjusting the seat carrier between a lower starting position and an end position. The drive unit for adjusting the seat carrier is formed beyond a height end position which is fixed during normal operation.

Abstract: The invention relates to an adjustment device for motor vehicle seats, in particular a height adjustment device, comprising a length-adjustable control unit which is suitable for adjusting and supporting a seat structure with respect to a seat base assembly and which can be articulated at one end to the seat structure and at the other end to the seat base assembly. In order to provide an adjustment device and a motor vehicle seat comprising an adjustment device, in which a bending direction of the adjustment device is predetermined in the event of a crash, the control unit is designed at least one of at one end and at both ends to be a pivotable and, in the event of a crash, slidable mounting with respect to at least one of the seat structure and the seat base assembly.

Abstract: The seat depth adjustable motor vehicle seat comprises a first seat part, a second seat part and a longitudinal adjustment device interposed between the first seat part and the second seat part and allowing for displacement movement in a first seat direction of the first seat part relative to the second seat part. The seat further comprises a toothed rack connected to the second seat part and extending substantially in the first seat direction. A primary gear meshes with the toothed rack. A secondary gear is in rotating communication with the primary gear. A toothed bar extends substantially in a second seat direction and engages the secondary gear. A third seat part is slidably disposed in the second seat direction and is connected to the toothed bar.

Abstract: A joint fitting for a vehicle seat with a forward tiltable seat back. The joint fitting has a first fitting part, a second fitting part and a pivot joint pivotally joining these two fitting parts. A locking cam is hinged to the first fitting part and is pivotal about a cam axle, the locking cam has a first end region located in proximity to the cam axle and a second end region. A locking bight is configured on the second fitting part and is provided with a first locking side and with a facing second locking side, the distance between these locking sides matching the distance between the two end regions. An actuation device acts on the locking cam at a distance from the cam axle so that the locking cam may be moved from a locking position into a release position. In the locking position, the first end region of the locking cam abuts on the first locking side and the second end region of the locking cam abuts on the second locking side.
