Restraining protective seat for infants

Abstract

An infant-restraining protective seat includes a shoulder-belt adjusting device (6) provided on a seat back. The shoulder-belt adjusting device (6) includes a belt guide (101) for guiding shoulder belts (5a) in such a manner that the position of the shoulder belts can be adjusted up or down, supporting means (102) for supporting the belt guide (101), a vertically extending screw shaft (103) for moving the supporting means (102) up and down, an operating knob (104) turnably attached to the left side wall (33) of the seat back (3), and a torque link (105) which connects the operating knob (104) and the screw shaft (103) while producing a right-angle change in direction, and which transmits the rotational torque of the operating knob (104) to the screw shaft (103). The lower end of the screw shaft (103) is supported so as to be capable of rotating in a state in which the shaft is supported in the thrust direction by means of a lower bracket ( 37).
