OCCUPANT PROTECTION DEVICE

An occupant protection device (S) is of a configuration such that a folded airbag (25,25A,25B) is housed and held in a holding body (10) disposed in front of a hip portion (MW) of an occupant (MP) seated in a seat (1). The airbag is configured in such a way as to protrude from the holding body owing to an inflating gas being caused to flow into an interior, and inflate in such a way as to cover a region in front of the occupant, and includes an occupant side wall portion (32,32A,32B) that is disposed on the occupant side when inflation is completed, and can restrain an upper body (MU) of the occupant. The occupant side wall portion is such that a lower side restraining face (41b), which can restrain a range from an abdominal portion (MA) to a chest portion (MB) of the occupant, and an upper side restraining face (41a), which can restrain a head portion (MH) or a shoulder portion (MS) of the occupant, are disposed on a rear face side when inflation is completed, and a bended portion (34,34A,34B) is disposed in a boundary region between the upper side restraining face and the lower side restraining face in such a way as to cause the upper side restraining face to protrude to the occupant side with respect to the lower side restraining face.
