摘要:
A seat longitudinal adjusting mechanism for a motor vehicle seat with a guide rail unit consisting of two rails enclosing therebetween a hollow space and longitudinally displaceably supported at one another. A toothed rack connected with one rail extends within the hollow space, into which engages a pinion supported in a pinion cassette. The pinion is driven by an adjusting gear. For facilitating the assembly, a preassembly rail extending in the rail longitudinal direction is provided which includes fastening means for fastening the pinion cassette at the preassembly rail, independently of the rails, whereby the length of the preassembly rail is essentially equal to the distance of the pinion cassette from one end of the other rail. The preassembly rail preassembled together with the pinion cassette can then be inserted correspondingly into the other rail.
摘要:
An arrangement for the form-locking guidance of a load supported by a top rail, especially of an electrically longitudinally adjustable motor vehicle seat, along at least one bottom rail, in which the bottom rail includes flanks surrounding a base of the top rail on both sides thereof; ball races are provided at the inner sides of the flanks which cooperate with ball races at the base of the top rail; the base of the top rail is slidingly supported on an upwardly pointing bearing surface of the bottom rail located between the flanks of the bottom rail.

A rear headrest adjusting arrangement in a motor vehicle has a headrest pivot bearing unit that is fixed at the seat and at which two head pad holding devices are disposed that are spaced away from one another in the direction of the pivotal axis. A pivot bearing shaft is provided that has two connecting parts for the holding devices, the connecting parts being spaced away from one another and being connected with the pivot bearing shaft in a torsionally fixed way. A driving motor is provided adjacent to the pivot bearing shaft, the driving motor having a motor shaft that with respect to its axis is parallel to the pivot bearing shaft and having a gearbox that connects the motor shaft with the pivot bearing shaft. This provides the possibility of a motor-driven headrest adjusting arrangement with little installation space for the pivot bearing unit.
摘要:
A seat adjustment mechanism especially suited for motor vehicle seats is composed of at least one motor mechanism for adjustably moving a seat member through a drive connection having at least two mutually engaging force transmission parts. In order to avoid rattling of the adjustment mechanism when adjusting movement of the seat is to be effected in a direction where the adjusting movement is abetted by the weight of the seat member itself, a braking device is provided which counteracts the adjusting force of the motor mechanism applied in that direction.
摘要:
A seat cushion adjustment device depends on an adjustment path of at least one main adjustment of the seat and serves to define a development curve of the seat cushion adjustment individually and ergonomically. The seat cushion adjustment device includes a first adjustment device for a main adjustment of the vehicle seat within a defined adjustment area and a second adjustment device coupled to the first adjustment device for adjusting the seat cushion in dependence on a main adjustment of the seat cushion in dependence on a main adjustment of the vehicle seat. The seat cushion adjustment device also includes a separate adjustment device coupled to said first or second adjustment device for fixing the development curve of the seat cushion adjustment device within a restricted adjustment area, whereby the extreme positions of the seat cushion are associated with the extreme positions of at least one main adjustment of the vehicle seat.
摘要:
A seat cushion adjustment for vehicle seats, more particularly the seats of motor vehicles, depends on the adjustment path of at least one main adjustment of the seat and serves for adapting the development curve of the seat cushion adjustment individually and ergonomically. The seat cushion adjustment includes a first adjustment for a main adjustment of the vehicle seat within a defined adjustment area, and a second adjustment coupled to the first adjustment for adjusting the seat cushion in dependence on a main adjustment of the vehicle seat. The seat cushion adjustment also includes a separate adjustment coupled to the first or second adjustment for fixing the development curve of the seat cushion adjustment within a restricted adjustment area, whereby the extreme positions of the seat cushion are associated with the extreme positions of at least one main adjustment of the vehicle seat. Configured in this manner, the seat cushion adjustment eliminates the possibility that the predetermined outer adjustment range limits of the seat cushion will be exceeded.
摘要:
The window in the door of a motorcar may be raised and lowered by means of a lifting mechanism including an electric motor connected to a speed reducing, worm gear transmission and a lifting arm turned by the output shaft of the transmission through further speed-reducing gears. The stroke of the window movement is limited by cooperating fixed, but adjustable abutments on supporting structure and an abutment connected to the output shaft of the worm gear transmission for joint rotation.

Adjusting mechanism for a seat, particularly a seat of an automotive vehicle, in which the seat rests on carriers elongated in the direction of shifting movement, seat shifting guides being interposed, and the carriers being equipped with integrally connected, upwardly directed lugs which laterally back the seat shifting guides.
摘要:
A mounting arrangement for a vehicle seat assembly including an electrically operated seat adjusting device which permits expedient fastening of the seat assembly to a vehicle floor and which essentially consists of lockable engaging connections provided on at least one side of the seat adjusting device as the fastening mechanism between the seat adjusting device and the vehicle floor and/or between a seat shell of the seat assembly and the seat adjusting device. On the opposite side of the seat adjusting device there are provided fastening connections preferably formed as screw connections which may be tightened to lock said engaging connections for a firm fastening of the assembly. The seat adjusting device is adapted to be manually operated by an auxiliary actuating device in the event of malfunction of elements thereof such as drive motors, gear units or interconnecting flexible shafts.
