A gear for an adjusting device with includes a gear spindle () and a spindle nut () exhibiting an internal thread (). The spindle nut () rests on the spindle () and the inner thread () of the spindle nut () engages with the spindle thread (). A bearing sleeve (), which exhibits a bearing section () for supporting the spindle nut (), is provided on either side of the spindle nut (). At least one bearing sleeve () has a guide section () for guiding the spindle nut () relative to thread spindle ().

Gear for an adjusting device

The invention relates to a vehicle seat with a back rest having a frame () and a lordosis support (), with the following additional configuration: The lordosis support () comprises a pressure plate () that is essentially bend resistant in at least the transverse direction of the seat or the Y-direction, forms a supporting surface in the lordosis region of the back rest and is arranged between two side frame parts () of the frame (); there is at least one holding element () that extends between the side frame parts () with a length-variable adjustment section (), which runs in the Y-direction and connects to the pressure plate (), and is affixed there at fixing points () arranged opposite each other; in an inoperative position, the pressure plate () is arranged with a horizontal clearance () or a clearance in the X-direction behind the fixing points (); there is a driving device with which the length of the adjustment section can be shortened as the horizontal clearance is reduced.

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.

The invention relates to a longitudinal scat adjustment device having an upper rail and a lower rail. The upper rail sits in the lower rail. Between the two rails a spindle is fixedly connected to the lower rail. Drivable on the spindle is a transmission, which can be retained in a specific manner by slotted bridges in the case of a crash.
