A spindle or worm drive for adjusting devices, especially seat adjustment devices, window lifters and sliding roofs, in motor vehicles. The drive includes a fixed spindle or relatively fixed toothed rack which is secured to the second of the two parts. The gear elements are mounted in a housing which includes at least two plates that can be secured to each other by plug-in connectors. The connectors are also configured as supporting joints that absorb the forces of the gear.

Spindle or worm drive for adjusting devices in motor vehicles

A drive for adjusting devices includes gear elements mounted in a gear housing which includes at least two plates that can be secured to each other by plug connectors. The connectors are also configured as supporting joints that absorb the forces of the gear elements. A method for assembling the gear housing includes prefitting the gear elements and the housing plates by fitting the housing plates together about the gear elements with plug connectors, holding the housing plates with a holding device with sufficiently light holding forces so that the housing plates can be aligned when the gear elements are turned, turning the gear elements for the purpose of aligning bearing points of the gear elements, and securing the position of the gear elements and the housing plates relative to each other by permanently fixing the position of the housing plates in all three-dimensional directions through action on the plug connectors.

Method of forming a housing for gear elements

A spindle and worm drive for adjusting devices, especially seat adjustment devices, window lifters and sliding roofs, in motor vehicles. The drive includes a fixed spindle or relatively fixed toothed rack which is secured to one of relatively two moving parts and gear elements mounted in a housing which includes at least two plates that can be secured to each other by plug-in connectors. The connectors are also configured as supporting joints that absorb the forces of the gear.

An automobile seat includes a seat frame; a backrest swivel mounted on the seat frame which can be folded forwards towards the seat surface; a longitudinal guide with which the seat frame can be moved in the longitudinal direction of the seat in order to regulate the longitudinal position of the seat; a fixing device for locking the seat frame in a previously regulated seat longitudinal position; an operating element for unlocking the fixing device; a coupling mechanism which unlocks the fixing device when the back rest is folded forwards towards the seat surface; a memory device by means of which the seat frame can automatically be stopped in a predeterminable seat longitudinal position (memory position); a regulating device of the memory device with which the memory position can be regulated in the longitudinal direction of the seat; a locking device of the memory device for locking a regulated memory position; and a switching device with which the locking device can be unlocked in order to be able to adjust the memory position. The coupling mechanism only acts on the operating element to unlock the fixing device for as long as the backrest is folded forwards, and the seat frame can be locked by the fixing device when the backrest is not folded forwards.
