Abstract
Abstract A seat track assembly is disclosed that comprises a fixed channel member and a sliding channel member disposed on the fixed channel member. The channel members are interfitted with generally U-shaped engagement members. A first ball bearing assembly is disposed at one vertical position between the two channels, and a second disc-shaped bearing is disposed at a lower vertical position between the U-shaped flanges of the two channels. The second bearing provides support in both the vertical and horizontal directions to prevent seizing between the two channels. The second bearing is resilient and acts to prevent seizing of the two channels by providing a resilient force vertically in opposition to the upward force created by the seat back when the seat is unoccupied and also provides resilient forces horizontally to prevent seizing due to twisting of the channels.

Total Claims: 3
Claim 1
Independent Claim
239 words
A track assembly for allowing axial positioning of an automobile seat comprising: an upper channel assembly fixed to a vehicle seat; a lower channel assembly fixed to a vehicle floor; said upper channel assembly being slidably mounted on said lower channel assembly; said upper channel assembly having a base and being generally C-shaped with both ends of said C-shape channel assembly being turned inwardly into generally U-shaped flanges, said lower channel being generally C-shaped with both ends of the C-shape channel being turned outwardly into generally U-shaped flanges, and said U-shaped flanges each having a base portion; said upper channel being horizontally wider than said lower channel; said lower channel U-shaped flanges extending into said upper channel U-shaped flanges; a first bearing member being disposed between said upper channel base and a base portion of said lower channel U-shaped flange; a bearing assembly being disposed between said U-shaped flanges of both said upper and lower channels to resist vertical and side loads on said track assembly; and said bearing assembly is disposed between, and abuts, said U-shaped flanges along both a vertical and a horizontal axis, and said bearing assembly comprises a second bearing member and a resilient support member, said resilient support member being disposed between said second bearing member and said upper channel U-shaped flange, and further wherein said resilient support member abuts and provides support for said second bearing member in both vertical and horizontal directions.
