a seatbelt configured to restrain an occupant on a vehicle seat, the occupant sitting in the vehicle seat; and
an upper-body restraint air-bag configured to perform expanding spread between a shoulder belt of the seatbelt and a chest region of the occupant and to restrain at least the chest region of the occupant, by receiving supply of gas from an inflator, at a time of frontal collision of a vehicle, wherein
in the upper-body restraint air-bag after completion of the expanding spread,
an area of the upper-body restraint air-bag on an opposite shoulder belt side in front view is set so as to be smaller than an area of the upper-body restraint air-bag on a shoulder belt side in the front view, the opposite shoulder belt side being opposite to the shoulder belt side, and
the upper-body restraint air-bag is configured such that the upper-body restraint air-bag on the shoulder belt side restrains the occupant from a shoulder region to an abdominal region and the upper-body restraint air-bag on the opposite shoulder belt side restrains the occupant from the shoulder region to the chest region.
