Title: Occupant protecting device

Abstract: In an occupant protecting device including an expandable bag housed within a belt for holding back an occupant upon collision of a vehicle, an outlet opening 33.sub.1 in a buckle-side duct 28 and an inlet opening 18.sub.3 in a tongue-side duct 18 are opposed to each other through a gap .alpha., and a seal member 35 made of a rubber and integrally provided with an outer lip portion 35.sub.2 and an inner breakable portion 35.sub.3 is mounted to the outlet opening 33.sub.1. When a gas generated by an inflater upon collision of the vehicle is supplied to the buckle-side duct, the breakable portion 35.sub.3 of the seal member 35 is broken to bring the lip portion 35.sub.2 into close contact with the inlet opening 18.sub.3, so that the gas is supplied from the buckle-side duct 28 through the tongue-side duct 18 to a shoulder belt, thereby expanding a bag housed in the shoulder belt. Thus, it is possible to easily and reliably perform the sealing of a gas passage in a connection between a buckle 31 and a tongue 19.
