Vehicular infant safety seat with seat back safety stopper

摘要

An infant safety seat is provided on the rear side of an automobile seat back which is pivotable about a base hinge mechanism, between a position in which it leans to the rear so as to accommodate an adult passenger on the regular seat cushion, and a positon in which it leans forward so as to allow a removable infant safety seat cushion to be attached to the seat back. A seat back stopper is formed on the front edge of the removable infant safety seat. The seat back stopper projects between the bottom of the seat back frame and the relatively stationary seat cushion frame. With this arrangement if forces acting on the seat back in the rearward direction cause the dog clutch of a reclining mechanism of the seat back to fail, the seat back is prevented from rotating backwards and crushing the infant by means of the seat back stopper. Thus, it becomes unnecessary to provide a specially reinforced reclining mechanism on seats on which a rear mounted infant seat are to be mounted.
