Abstract
A seat track assembly including a first rail and a second rail spaced apart by a distance and extending parallel with respect to one another, wherein at least one of the first and second rails having a first receiver, a second receiver, the first and second receivers longitudinally translatable with respect to each other, and a sliding member disposed therebetween, wherein the sliding member defines an aperture extending at least partially therethrough.
Claims20
A sliding member comprising:
- an elongated tube comprising a body including a low friction material, wherein the elongated tube includes an inner surface defining an aperture,
- wherein:
- a spring is disposed within the aperture and adapted to provide an outwardly biasing force against the low friction material,
- wherein the aperture comprises a plurality of apertures each extending at least partially through the elongated tube,
- a substrate is disposed within the aperture, or
- a combination thereof.
A linear motion assembly comprising:
- a first member;
- a second member;
- and
- a sliding member disposed between the first and second members,
- wherein at least one of the first and second members is adapted to longitudinally translate with respect to the sliding member, and wherein the sliding member comprises:
- an elongated tube comprising a body including low friction material, and wherein the elongated tube defines an aperture extending along a longitudinal length thereof, or
- a substrate having an elongated shape and a low friction material disposed around the substrate, wherein:
- at least one of the axial ends of the substrate is exposed from the low friction material,
- the low friction material comprises a gap extending along at least a portion of an axial length of the sliding member,
- a void is disposed between a portion of the substrate and the low friction material, or
- a combination thereof.
A seat track assembly comprising:
- a first receiver adapted to be coupled to a seat;
- a second receiver adapted to be coupled to a surface, the first and second receivers being longitudinally translatable with respect to each other;
- and
- a sliding member disposed between the first and second receivers, wherein the sliding member comprises:
- a low friction material including an aperture extending along a longitudinal length of the sliding member, or
- a substrate having an elongated shape and a low friction material disposed around the substrate.
