Abstract

Abstract An auto booster seat adapted to be positioned on the seat of a vehicle to support a child and for functioning in cooperation with a conventional seat belt to secure the child and auto booster seat with respect to the seat of a car in the event of an accident or sudden acceleration or deceleration. The auto booster seat comprises a seating shell in a generally rectangular configuration and has parallel side edges and parallel front and rear edges, a lower surface positionable on the seat of the vehicle and an upper surface having a pad for receipt of a child sitting thereon. The seating shell has projections extending upwardly from the upper surface along the side edges. Each projection has a forward extent adjacent to the front edge and a rearward extent adjacent to the rear edge. A generally U-shaped cutout is formed into each projection with upwardly directed front and rear parallel surfaces. The front and rear surfaces extend from the forward extent of the projections and angle downwardly toward the rearward extent. A guide pin is formed in each front surface and each rear surface with the guide pins of each projection being in axial alignment with each other at about 90 degrees from the surface.
