Abstract
An infant-restraining protective seat includes an upper bracket (50) secured to a seat back. In order that a seat back (3) may be locked at any of three reclining angles, three locking holes (65), (66), (67) through which a locking pin (56) is passed are provided in a circular portion (50b) of the upper bracket on the circumference of a circle of a prescribed radius from the center of the circular portion. In order to lock the seat back at a folded position, the circular portion (50b) is provided with a locking hole (68), located on the same circumference as the locking holes (65), (66), (67), through which the locking pin (56) is passed. Each of the locking holes (65), (66), (67), (68) is elliptical in form, with the ellipse having a minor axis (f) and a major axis (b). In this case, the minor axis (f) is set to have a size that allows the locking pin (56) to be passed through and slid along the hole with almost no gap between the pin (55) and the walls of the hole. The locking holes (65) , (66) , (67) , (58) are so arranged that the minor axis (f) of each hole lies in the circumferential direction of a circle concentric with a hole (64) .
