ABSTRACT:
Disclosed is an inflatable seat belt apparatus in which, under ordinary conditions, a shoulder belt (2) is maintained in a belt-shaped form and a movable lever (7d) is maintained in contact with a main body (7a) at an opening-area reducing position. Accordingly, the belt (2) is prevented from turning over and twisting so similar to that of the conventional seat belt apparatus. In the event of an emergency such as a vehicular collision, a gas generator (8) is actuated and generates a gas which causes a shoulder belt portion (2a) between the gas generator (8) and the intermediate guide (7) to inflate. The gas which has filled the portion 2(a) of the shoulder belt causes the movable lever (7d) to move to the position at which it enlarges the opening area of the through-hole. Accordingly, the gas easily flows into the shoulder belt (7b) ahead of the intermediate guide (7). Thus, the shoulder belt (7) expands instantaneously and in reliable fashion.
