Abstract

Abstract 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.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 207 words
An installation for the form-locking guidance of a motor vehicle seat supported by a top rail means along at least one bottom rail means, in which the top rail means includes a base and the bottom rail means includes flanks surrounding the base of the top rail means on both sides thereof, the flanks being provided at the inner sides thereof with ball races cooperating with ball races provided at the base of the top rail means, the bottom rail means further including an upwardly pointing bearing surface means between the flanks thereof, the base of the top rail means being slidingly supported on the upwardly pointing bearing surface means of the bottom rail means characterized in that said base is a component of said top rail extending downwardly from a cross leg of said top rail into the proximity of said bearing surface and being supported on said bearing surface by means of its bottom with braking means provided between the undersurface of said bottom and said bearing surface, and wherein the bottom of the base has a larger area than the cross-sectional area at the top of the base by virtue of extending beyond the top of the base on both sides of the base.
Claim 2
Dependent Claim 207 words
An installation for the form-locking guidance of a motor vehicle seat supported by a top rail means along at least one bottom rail means, in which the top rail means includes a base and the bottom rail means includes flanks surrounding the base of the top rail means on both sides thereof, the flanks being provided at the inner sides thereof with ball races cooperating with ball races provided at the base of the top rail means, the bottom rail means further including an upwardly pointing bearing surface means between the flanks thereof, the base of the top rail means being slidingly supported on the upwardly pointing bearing surface means of the bottom rail means characterized in that said base is a component of said top rail extending downwardly from a cross leg of said top rail into the proximity of said bearing surface and being supported on said bearing surface by means of its bottom with braking means provided between the undersurface of said bottom and said bearing surface, and wherein the bottom of the base has a larger area than the cross-sectional area at the top of the base by virtue of extending beyond the top of the base on both sides of the base.
Claim 3
Dependent Claim 35 words

Dependent Claim 12 words
An installation according to claim 3, wherein the projections are constructed elastic.
Claim 7
Dependent Claim 18 words
An installation according to claim 3, wherein the projections are elongated in the direction of the rail means.
Claim 8
Dependent Claim 15 words
An installation according to claim 2, wherein the brake surface means are coated with fibers.
Claim 9
Dependent Claim 12 words
An installation according to claim 7, wherein said fibers consist of polyamide.
Claim 10
Dependent Claim 12 words
An installation according to claim 6, wherein the projections are constructed solid.
Claim 11
Dependent Claim 12 words
An installation according to claim 6, wherein the projections are constructed elastic.
Claim 12
Dependent Claim 40 words
An installation according to claim 1, wherein at least one of the bottom surface of the base and the bearing surface means of the bottom rail means is subdivided into strips extending in the longitudinal direction of the rail means.
Claim 13
Dependent Claim 35 words
An installation according to claim 11, wherein at least one of the bearing surface means of the bottom rail means and the bottom surface of the base is provided with a slide and brake coating.
Claim 14
Dependent Claim 12 words
An installation according to claim 12, wherein said coating consists of polyamide.
Claim 15
Dependent Claim 37 words
An installation according to claim 12, wherein the slide and brake coating is disposed on a support secured at one of the bearing surface means of the bottom rail means and the bottom surface of the base.
Claim 16
Dependent Claim 16 words
An installation according to claim 14, wherein said support consists of copper or a copper alloy.
Claim 17
Dependent Claim 25 words
An installation according to claim 1, wherein the brake means includes projections protruding toward at least one of the bearing surface means and bottom surface.
Claim 18
Dependent Claim 12 words
An installation according to claim 16, wherein the projections are constructed solid.
Claim 19
Dependent Claim 12 words
An installation according to claim 16, wherein the projections are constructed elastic.
Claim 20
Dependent Claim 18 words
An installation according to claim 16, wherein the projections are elongated in the direction of the rail means.
