EP0117131A2 — Longitudinal slide mechanism for a vehicle seat

Claim 1

Independent Claim 249 words

A longitudinal slide mechanism for a vehicle seat, the mechanism comprising first and second elongate members relatively slidable along their longitudinal axes, and locking means for locking the members against longitudinal movement in any one of a plurality of positions, in which the first member has a central web, two side webs each extending substantially at right angles from a respective side of the central web, each side web terminating in_an interlock section comprising a first part extending substantially at right angles from the side web, a second part extending substantially at right angles from the first part towards the plane of the central web and a third part extending substantially at right angles from the second part towards the adjacent side web; the second member has a central web, two side webs each extending substantially at right angles from a respective side of the central web, each side web terminating in an interlock section comprising a first part extending substantially at right angles from the side web, a second part extending substantially at right angles from the first part towards the central web and a third part extending substantially at right angles to the second part towards the repective side web; the third part of each of the interlocking sections of one of the members is received between the first and third parts of the adjacent interlocking section of the other of the members; and the interlocking sections are of constant cross-section throughout the length of the members.

Claim 2

Dependent Claim 249 words

A longitudinal slide mechanism for a vehicle seat, the mechanism comprising first and second elongate members relatively slidable along their longitudinal axes, and locking means for locking the members against longitudinal movement in any one of a plurality of positions, in which the first member has a central web, two side webs each extending substantially at right angles from a respective side of the central web, each side web terminating in_an interlock section comprising a first part extending substantially at right angles from the side web, a second part extending substantially at right angles from the first part towards the plane of the central web and a third part extending substantially at right angles from the second part towards the adjacent side web; the second member has a central web, two side webs each extending substantially at right angles from a respective side of the central web, each side web terminating in an interlock section comprising a first part extending substantially at right angles from the side web, a second part extending substantially at right angles from the first part towards the central web and a third part extending substantially at right angles to the second part towards the repective side web; the third part of each of the interlocking sections of one of the members is received between the first and third parts of the adjacent interlocking section of the other of the members; and the interlocking sections are of constant cross-section throughout the length of the members.

Claim 3

Dependent Claim 50 words

A mechanism according to claim 1 in which each interlocking section of the first member also has a fourth part extending substantially at right angles from the third part and a fifth part extending , substantially at right angles from the fourth part towards the plane of the second part.

Claim 4

Dependent Claim 49 words

A mechanism according to claim 1 or claim 2 and including spaced roller assemblies disposed between the central web of one of said members and the first parts of the interlocking sections of the other of said members, the roller assemblies supporting the two members for relative longitudinal movement.

Claim 5

Dependent Claim 51 words

A mechanism according to claim 1 or claim 2 and including spaced roller assemblies disposed between the side webs of one of the members and the respective adjacent second parts of the interlock sections of the other of the members, the roller assemblies supporting the two members for relative longitudinal movement.

Claim 6

Dependent Claim 30 words

A mechanism according to claim 3 or claim 4 in which each roller assembly comprises rollers at each side of the mechanism, the rollers being captive in a common carrier.

Claim 7

Dependent Claim 85 words

A mechanism according to claim 5 in which the carrier comprises a plate lying adjacent to the central web of one of said members and parallel to and between the first and second members, the plate having at each side thereof a side portion extending substantially at right angles to the plate and lying between the side web of the member to which the plate is adjacent and the second part of the interlocking section of the lower member from which the plate is remote.

Claim 8

Dependent Claim 40 words

A mechanism according to claim 6 in which each side portion of the plate terminates in a flange extending inwardly towards the longitudinal axis of the mechanism and lying between respective parts of the interlocking sections of the two members.

Claim 9

Dependent Claim 43 words

A mechanism according to any of claims 1 to 7 in which one side web of one of the members is provided with a series of holes engageable by elements of a locking member that is pivoted to the other of the members.
