Abstract
Abstract A seat slide comprises a guide channel and a slide part which is attached to the seat and slides within the channel. To afford free sliding movement considerable play is provided between the slide part and the guide channel but to avoid rattle particularly when the seat is not occupied, resiliently deformable plastics pads are located in the clearance gaps between the channel and the slide part to take up the play. These plastics pads not only take up the play but also facilitate sliding movement in that they can be made of a material having a low coefficient of friction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
221 words
A seat slide for supporting a vehicle seat above the floor of a vehicle, comprising a first member in the form of a guide channel having a base, side walls with in-turned flanges and an opening between said in-turned flanges, a second elongate member mounted in the guide channel for lengthwise sliding therein, said second member having first and second surfaces which respectively confront the base and the in-turned flanges of the first member, and at least one resiliently deformable element located in said first member between the base thereof and said first surface of the second member, each such element being resiliently deformable from a first configuration in which it resiliently urges the second member away from the base of the first member to cause said second surface of the second member to abut the in-turned flanges of the first member, and a second configuration in which it allows the second member to move towards the base of the first member to an extent sufficient to create a clearance between said in-turned flanges and the second surface of said second member, said at least one element being caused to assume said second configuration in response to loads applied to the slide in a direction perpendicular to said base and serving to transmit such loads between the first and second members.
Claim 2
Dependent Claim
221 words
A seat slide for supporting a vehicle seat above the floor of a vehicle, comprising a first member in the form of a guide channel having a base, side walls with in-turned flanges and an opening between said in-turned flanges, a second elongate member mounted in the guide channel for lengthwise sliding therein, said second member having first and second surfaces which respectively confront the base and the in-turned flanges of the first member, and at least one resiliently deformable element located in said first member between the base thereof and said first surface of the second member, each such element being resiliently deformable from a first configuration in which it resiliently urges the second member away from the base of the first member to cause said second surface of the second member to abut the in-turned flanges of the first member, and a second configuration in which it allows the second member to move towards the base of the first member to an extent sufficient to create a clearance between said in-turned flanges and the second surface of said second member, said at least one element being caused to assume said second configuration in response to loads applied to the slide in a direction perpendicular to said base and serving to transmit such loads between the first and second members.
Claim 3
Dependent Claim
29 words
A seat slide as claimed in claim 1 in which said at least one element is arcuate when in said first configuration and flat when in said second configuration.
Claim 4
Dependent Claim
50 words
A seat slide as claimed in claim 2 in which said at least one element, when in said first configuration, has end portions thereof in contact with one of said first and second members and an intermediate portion thereof in contact with the other of said first and second members.
Claim 5
Dependent Claim
82 words
A seat slide as claimed in claim 1 in which said at least one element comprises a main body whose thickness is less than the internal separation between said base and said first surface when said second surface is in abutment with the in-turned flanges, and at least one integral tongue projecting from the body to cause abutment between said surface and the in-turned flanges as aforesaid, the tongue being deflectable back towards the body when the slide is subject to loading.
Claim 6
Dependent Claim
26 words
A seat slide as claimed in claim 1 in which said at least one element is of an overall width greater than said second slide member.
Claim 7
Dependent Claim
21 words
A seat slide as claimed in claim 5 in which the sides of said at least one element are outwardly convex.
Claim 8
Dependent Claim
47 words
A seat slide as claimed in claim 1 in which said at least one element is provided with integral tongues at each side thereof which, when unstressed, project laterally outwardly, said tongues engaging the side walls of said channel and being deflected thereby inwardly of the channel.
Claim 9
Dependent Claim
29 words
A seat slide as claimed in claim 1 in which said at least one element is anchored at one end only to one of said first and second members.
Claim 10
Dependent Claim
40 words
A seat slide as claimed in claim 1 in which said at least one element includes a pair of spaced legs joined at one end by a bridge portion which is anchored to one of said first and second members.
