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.
