  • Patent number: 9889781
    Abstract: A vehicle seat (1) includes a seat part (3), a backrest (2) a fitting (10) including a first fitting part (11) rotatable relative to a second fitting part (12) about an axis (A) and relative to the seat part that is pivotable about the axis (A). A first adapter (20) fixedly connects the first fitting part to a structure of the backrest or seat part. A second adapter (50) fixedly connects the second fitting part with the other of the structure of the seat part or backrest. A first stop (25) on the first adapter (20) and a second stop (60), integrally formed with the second adapter (50) and surfaces from an edge transition of the second adapter (50), interact to limit a pivot angle of the backrest. The second stop (60) comprises a limb (61), extending from the edge transition (54), in a radial direction, toward the axis (A).

  • Patent number: 8191850
    Abstract: A longitudinal adjuster, in particular for a vehicle seat, has at least one first seat rail (2) and, at least one second seat rail (3) which is arranged in a manner such that it can be displaced in a sliding manner relative to the first seat rail (2), and at least one end stop (11, 21, 31, 41, 51) which is attached to the first seat rail (2) and limits the relative displaceability of the two seat rails (2, 3) to each other by means of interaction with a second end stop (3a) which is formed by the second seat rail (3) or is attached to same. The first seat rail (2) is provided with at least two apertures (2e) through each of which protrudes a region of the end stop (11, 21, 31, 41, 51) serving to limit the seat rail movement in the longitudinal direction of the seat rails (2, 3), and the region is formed by a respective tab (11a, 21a, 31a, 41a, 51a); formed integrally with the end stop (11, 21, 31, 41, 51).

  • Patent number: 7669824
    Abstract: The invention relates to a drive for adjusting motor vehicle seats comprising a spindle (5) fixed to a first (4) of two rails (3, 4) which are adjustable with respect to each other with the aid of holding devices (60) arranged on the end of the spindle (5). A transmission (9) actuated by a motor (2) is placed on the second rail (3), According to id invention, the holding devices (60) comprise an external bowl-shaped supporting surface (66) in which each end of the spindle (5) is fixedly mounted, respectively. Said solution is more advantageous in comparison with conventional holding devices which are embodied in the form of flexible stamped parts, in particular the inventive holding devices exhibit a high resistance in the case of crash.

  • Patent number: 7571666
    Abstract: Case parts of an adjustment mechanism for a seat adjustment device of a motor vehicle can be joined together along a parting line via joint surfaces. The joint surfaces are provided for the purpose of reciprocal placement of the case parts by way of a joining process. Contact surfaces of the case parts are present in addition to the joint surfaces The contact surfaces are in non-parallel alignment to the joint surfaces. Transferred gear forces running parallel to at least a section of the joint surfaces are absorbed by the contact surfaces. The case parts are fastened to one another by way of screw connections. The contact surfaces of the one case part are respectively held in position with respect to the contact surfaces of the other case part solely due to the screw connections. With such a case, high loads can be absorbed in spite of a small size.
