In an adjusting gear in a motor vehicle, especially for a motor-driven seat adjustment mechanism, with an essentially pot-shaped transmission housing in which are supported on a bearing shaft, starting from the pot bottom, a pinion, a planet gear carrier with planet gears, a sun gear meshing with the planet gears as well as a worm gear non-rotatably connected with the sun gear; according to this invention, the end face of the planet gears opposite the pot bottom are provided with at least one orientation surface, the worm gear is also provided on its end face opposite the pot bottom with at least one orientation surface and the end face of the planet gears are each constructed with an abutment surface for the abutment at the worm gear. This enables a facilitated assembly of the adjusting gear, especially with the aid of an assembly robot.

Adjusting gear in motor vehicles

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.

Seat longitudinal adjusting mechanism

An installation 10 for the longitudinal adjustment of a seat, especially of a motor vehicle seat which includes a top rail 30 supporting the seat, which is form-lockingly longitudinally displaceably guided on a coordinated bottom rail 44. A drive mechanism 12 with drive pinion 24 is connected with one of the two rails; the drive pinion 24 engages into a toothed rack 56 mounted at the other rail 44 and extending along the same. In order to establish with a simple structure an always reliable mutual engagement of the pinion and toothed rack, also in case of high loads caused by accidents, the other rail 44 is provided with a guide groove 98 for at least one guide bolt 92 mounted at the drive mechanism 14 or at the rail 30 within the area of the pinion 24.

Installation for the longitudinal adjustment of a seat

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.

Arrangement for the form-locking guidance of a load supported by a top

An adjusting transmission of a motor vehicle for a motorized seat adjustment with a transmission housing and a worm arranged on a bearing shaft which is supported at the transmission housing in two shaft bearing parts retaining the shaft and inserted into a respective housing aperture on both sides of the worm; at least one of the two shaft bearing parts is thereby tiltably supported within the coordinated housing aperture in at least a plane containing the bearing shaft axis. A self-alignment of the two bearing parts is achieved thereby so that one obtains without large expenditures a transmission operation which is low in friction and freely movable. The bearing part can be constructed as ring with spherical surface which abuts at prism surfaces of the housing aperture as well as of a pressure member.
