ABSTRACT:
A belt anchor incorporating a seat track structure for a vehicle whereby the load applied when a emergency situation occurs is supported by the body of the vehicle through a seat mounted on the vehicle and the seat is supported on the vehicle body in such a manner as to be movable in the longitudinal direction of the vehicle. An upper rail which is rigidly secured to the seat is supported on a lower rail rigidly secured to the vehicle body in such a manner that the upper rail is movable along the lower rail in the longitudinal direction of the vehicle through first and second rotary support means. A belt anchor is rigidly secured to the upper rail, and a guide plate is rigidly secured to one edge portion of the lower rail in such a manner as to accommodate the second rotary support means defined by a plurality of balls and to clamp one edge portion of the upper rail by these balls. The other edge portion of the lower rail is formed such as to have a substantially U-shaped cross-section. One edge portion of the belt anchor is disposed within this U-shaped portion, and a slide piece is disposed between the U-shaped portion and the edge portion of the belt anchor. Accordingly, it is possible to prevent the upper and lower rails from moving relative to each other in the lateral direction of the vehicle.
