Drive of a seat adjusting device, especially for motor vehicles, with a spindle that is fastened on a first of two rails, which are adjustable with respect to each other by at least one mounting on one end of the spindle, and with a transmission driven by a motor that is mounted on the second rail, whereby the mounting is a single piece stamped bent part with a first area with at least one fastener opening and a second area that is offset upward relative to the first area for holding one end of the spindle, whereby the first area and the second area are connected to form a single piece by a transition area, whereby the second area is designed with a slot with legs lying opposite each other, at least in sections, and opposite a slot between which the end of the spindle can be fixed.

Drive of a seat adjusting device for motor vehicles

A worm wheel including first toothing regions transitioning into and on either side of a second toothing region and a complete annular surface on both ends of the worm wheel. The first toothing regions may have a constant outer diameter and the second toothing region may be depressed relative to the first toothing region. The first toothing regions may be globoid toothing regions and the second toothing region may be a cylindrical toothing region.

Drive for an adjustment device with a worm wheel having a globoid toothing with a cylindrical section

The invention involves a gearbox, especially for adjustment devices in motor vehicles, with a plastic worm drive. The invention provides that the worm drive has an encircling, circular flat contact surface perpendicular to the worm axle and a number of removal pockets in the form of recesses that are interposed axially between contact surface and the worm axle and at the same time arranged in a level recessed to the level of contact surface, whereby an encircling bevel is formed in the transition area from level of removal pockets to the level of the circular contact surface.

Gearbox for adjustment devices, especially in motor vehicles

The invention concerns a gearing for an adjustment device, especially an automotive adjustment device. Included is a threaded spindle as well as a spindle nut sitting on the threaded spindle, while inside a housing of the gearing. On either side of the spindle nut, there is provided a bearing bush to mount the spindle nut inside the gearing housing, while at least one of the bearing bushes consists of flexible material and is clamped under prestressing between the gearing housing and the spindle nut.

Gearing for an adjustment device with compensation for play

The invention relates to a drive for adjusting motor vehicle seats comprising a spindle () fixed to a first () of two rails () which are adjustable with respect to each other with the aid of holding devices () arranged on the end of the spindle (). A transmission () actuated by a motor () is placed on the second rail (), According to id invention, the holding devices () comprise an external bowl-shaped supporting surface () in which each end of the spindle () 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.
