Abstract
A roller track assembly includes an outer channel member and inner channel member having rollers attached and which vertically displaces in the channel of the outer channel member in response to inflation of an inflatable air bag in the channel of the outer channel member. A top plate is quick release attached to the outer channel member by a detent arrangement and covers the outer channel member and inner channel member. The top plate has openings through which rollers rotatably secured to the inner channel member selectively protrude in response to inflation of the air bag. Sealing covers prevent debris entering top plate openings from falling into the interface regions between the inner and outer channel members.
