An occupant restraining device for a vehicle that can regulate a position of a seat belt, without occupying vehicle cabin space. An air belt device includes a retractor that is arranged to the rear, in a vehicle front-rear direction, with respect to a seat back, a seat belt that is pulled out from the retractor when applied to an occupant and that includes a shoulder belt portion for restraining an upper body of the occupant, and a belt insertion portion that is formed by indenting a portion, in a seat width direction, of an upper end of the seat back, and into which an upper side portion of the shoulder belt portion of the seat belt is made to enter.

Occupant restraining device for a vehicle

An objective is to inflate an inflation portion to an upward position, corresponding with a temple area of an occupant, at the time of a side impact. At a shoulder portion of a seatbackof a vehicle seat, there is an inflation-time cross-sectional shape regulation component, through which an occupant restraint webbingpasses. The occupant restraint webbinghas an inflation portionthat corresponds with a cephalic regionH of an occupantat the time of inflation. At the time of inflation of the inflation portion, the inflation-time cross-sectional shape regulation componentregulates such that a cross-sectional shape of the inflation portionis an oblong shape which is long in a vertical direction. Therefore, an inflated shape of the inflation portionis regulated by the inflation-time cross-sectional shape regulation componentat the time of the side impact, and the inflation portioncan be caused to inflate up to a position corresponding with a temple portionS of the occupant. Thus, inertial force in a vehicle lateral direction of the cephalic regionH of the occupantcan be absorbed by the inflation portion
