An occupant protection device for protecting an occupant sitting in a front seat of a vehicle. The occupant protection device includes a front airbag device that is adapted to be mounted in front of the front seat and a roof airbag device that is adapted to be mounted on a roof of the vehicle. The front airbag device includes a front airbag that is inflatable and deployable for protecting an upper body of the occupant when an impact is applied to the vehicle from forward. The roof airbag includes a roof airbag that is inflatable and deployable downwardly between the front airbag and the front seat for protecting a head of the occupant when an impact is applied to the vehicle from forward.

An occupant protection device includes an airbag which is deployed and inflated with an amount of protrusion from a storage position to a rear side in an inflation completed state in a large protrusion amount mode and a small protrusion amount mode, and the airbag includes a bag body and a tether. The tether is connected to a length adjustment unit. The bag body has a tubular inflation portion curved in a substantially U shape from the storage position toward the tether connection portion. A shape of the bag body in the large protrusion amount mode is defined such that the tether connection portion is further moved rearward with respect to the inlet port on the inner peripheral surface side, as compared with the case of the small protrusion amount mode.

A seat device for a vehicle includes a seat for supporting a lower body of a vehicle occupant, and a backrest for supporting an upper body of the occupant. The seat device further includes an arresting portion that is stored in a storage position disposed in the seat. The arresting portion is configured to be deployed from the storage position and restrain a part of the lower body of the occupant from moving forward in the event of a collision of the vehicle.
