Runner for a vehicle seat, and a vehicle seat including such a runner
First Claim
1. A runner for a vehicle seat, the runner being of the type comprising a male rail and a female rail which define between them at least a first compartment in which rolling bearing elements are disposed to enable said male and female rails to move relative to each other along a longitudinal axis;
- said runner further comprising at least one shoe received in the first compartment and mounted to slide relative to one of the rails, namely the male rail or the female rail, and said shoe comprises at least a first rigid portion having a shape substantially complementary to the shape of the first compartment in order to offer contact zones for contact with the male rail and with the female rail when the runner is subjected to deformation in a first direction.

Abstract
A runner for a vehicle seat, the runner being of the type comprising a male rail (7) and a female rail (6) which define between them at least a first compartment (8) in which rolling bearing elements are disposed to enable said male and female rails to move relative to each other along a longitudinal axis. The runner further comprises at least one shoe (10) received in the first compartment (8) and mounted to slide relative to one of the rails, namely the male rail or the female rail, the shoe comprising at least a first rigid portion (11) having a shape substantially complementary to the shape of the first compartment in order to offer contact zones for contact with the male rail and with the female rail when the runner is subjected to deformation in a first direction.

8. A runner according to claim in which the second rigid portion of the shoe is received in the second compartment so as to offer contact zones for contact with said lip of the male rail and with the lip of the female rail when the runner is subjected to deformation in the second direction.
-
9. A runner according to claim in which:
-
the runner further comprises a first abutment system that is part of the male rail and a second abutment system that is part of the female rail, the first and second abutment systems being designed to co-operate with each other to limit the extent to which the male rail and the female rail can move relative to each other between two end-of-stroke positions and the first abutment system of the male rail is in the form of a projecting portion formed on the lip of said male rail; and
the second abutment system of the female rail is in the form of two abutment elements which are formed on said female rail and which are disposed on either side of the projecting portion in the longitudinal direction. - View Dependent Claims (10, 11)
