Automatic seatbelt system for vehicle

Abstract

An automatic seatbelt system for a vehicle, which is designed to restrain the body of an occupant when an emergency situation of the vehicle occurs, has a slider which retains one end of a webbing and which is movable along a guide rail laid on the body of the vehicle between a position at which the webbing is fastened to the occupant's body (hereinafter referred to as a 'webbing fastening position') and a position at which the webbing is unfastened therefrom (hereinafter referred to as a 'webbing unfastening position'), and a continuous member for moving the slider between the above-described two positions. The continuous member and the slider are allowed to move relative to each other by a predetermined amount. In addition, a member is provided at an end of the guide rail on the side thereof which is closer to the webbing fastening position, the member being adapted such that, when the slider is moved to the webbing fastening position, the member inhibits the slider from moving toward the webbing unfastening position, whereas, when the continuous member moves from the webbing fastening position toward the webbing unfastening position, the member is actuated by virtue of the relative movement occurring between the continuous member and the slider so as to allow the slider to move toward the webbing unfastening position. Accordingly, when the slider is at the webbing fastening position, it is inhibited from moving along the guide rail.
