Abstract
Abstract A seat-adjusting mechanism, particularly for vehicle seats, in which a seat frame is movably arranged in the vehicle longitudinal direction by slide members displaceable in guide rails and in which the fixing of the pre-selected seat position takes place by an engageable toothed arrangement; the slide members of one guide rail abut at least within the lower area thereof at the walls surrounding the same and the clearance between the upper edge of the slide members and the upper wall of the guide rails is compensated for by a spring-loaded cam rotatably supported between the slide members at the side walls of the seat frame.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
206 words
A seat-adjusting mechanism comprising guide rail means, slide means connected to at least one side wall of a seat frame, said slide means including first and second portions arranged for displacement in said guide rail means, said guide rail means including tooth means, shift-lock means carried by the side wall of the seat frame for engaging said tooth means to fix a selected seat position, said guide rail means including opposed upstanding walls and upper and lower walls surrounding said slide means, one of said walls having an aperture therethrough in which the connection of the side wall of the seat frame to said slide means is disposed, said slide means abutting at least at the lower wall of said guide rail means and having an upper edge thereof spaced from the upper wall of said guide rail means, and spring-loaded cam means rotatably supported at the side wall of the seat frame intermediate said first and second portions of said slide means for compensating for the space between the slide means and the upper wall of said guide rail means by abutting at the upper wall in a selected fixed position for preventing movement between the upper and lower wall of said guide rail means.
Claim 2
Dependent Claim
206 words
A seat-adjusting mechanism comprising guide rail means, slide means connected to at least one side wall of a seat frame, said slide means including first and second portions arranged for displacement in said guide rail means, said guide rail means including tooth means, shift-lock means carried by the side wall of the seat frame for engaging said tooth means to fix a selected seat position, said guide rail means including opposed upstanding walls and upper and lower walls surrounding said slide means, one of said walls having an aperture therethrough in which the connection of the side wall of the seat frame to said slide means is disposed, said slide means abutting at least at the lower wall of said guide rail means and having an upper edge thereof spaced from the upper wall of said guide rail means, and spring-loaded cam means rotatably supported at the side wall of the seat frame intermediate said first and second portions of said slide means for compensating for the space between the slide means and the upper wall of said guide rail means by abutting at the upper wall in a selected fixed position for preventing movement between the upper and lower wall of said guide rail means.
Claim 3
Dependent Claim
79 words
A seat-adjusting mechanism as defined in claim 1, wherein said shift-lock means is provided with a row of apertures adapted to receive said tooth means of said guide rail means, said shift-lock means being connected to a rod having an actuating lever connected thereto whereby movement of the actuating lever causes said shift-lock means to disengage from said tooth means and to contact said cam means to move said cam means out of abutment with said guide rail means.
Claim 4
Dependent Claim
53 words
A seat-adjusting mechanism as defined in claim 2, wherein said guide rail means includes two guide rails having said slide means displaceably arranged therein, and said slide means of one of said guide rails abutting at least within the lower area of the opposed upstanding walls and lower wall of said guide rail.
Claim 5
Dependent Claim
72 words
A seat-adjusting mechanism as defined in claim 3, wherein one of said shift-lock means is formed as a rigid member and includes a spring for biasing said rigid member into engagement with said tooth means of said guide rail means, said tooth means being a toothed bar projecting downwardly from each guide rail, and the other of said shift-lock means is formed as a resilient member for engagement with said tooth means.
Claim 6
Dependent Claim
40 words
A seat-adjusting mechanism as defined in claim 4, wherein said toothed bar is provided with teeth having a relatively narrow head portion which run out into a relatively wide base portion by way of inclined transition portions on both sides.
Claim 7
Dependent Claim
23 words
A seat-adjusting mechanism as defined in claim 5, wherein the seat is a vehicle seat arrangeD for adjustment in the vehicle longitudinal direction.
Claim 8
Dependent Claim
18 words
A seat-adjusting mechanism as defined in claim 6, wherein said slide means is formed of synthetic resinous material.
