An occupant protection device for protecting an occupant sitting in a seat includes an inflator, a holding member that is adapted to be disposed in front of a pelvic region of the occupant as sitting in the seat, and an airbag that is formed of a sheet material having flexibility and stored in and held by the holding member in a folded form. The airbag is configured to be inflated with an inflation gas fed by the inflator. The airbag includes a shoulder restraining portion that is configured to be deployed in front of shoulders of the occupant, and a supporting inflatable portion that is disposed in a lower end portion of the airbag as deployed for supporting the shoulder restraining portion. The supporting inflatable portion as deployed includes, in the underside, a supported surface that is adapted to be supported by thighs of the occupant.

An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag that is stored in the lap belt. The airbag as deployed includes a main inflatable portion for protecting an upper body of the occupant, and a head protecting portion that is located in a vicinity of an upper end of the main inflatable portion for protecting a head of the occupant. The head protecting portion includes a front inflatable portion for covering a front side of the head, and a pair of side inflatable portions that extend rearward from left and right ends of the front inflatable portion for covering sides of the head. Each of the side inflatable portions is configured to be deployed in such a manner that a space is formed between itself and the head.

Occupant protection system

An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag disposed in the lap belt. The airbag is coupled to the lap belt in such a manner as to be movable relative to the lap belt in a left and right direction, and includes a main inflatable portion that is deployable in front of upper body of the occupant, and a positioning inflatable portion that protrudes from a lower end region of the main inflatable portion. The positioning inflatable portion includes a contact surface that contacts and is supported by an environmental member which is disposed in a circumference of the lap belt at airbag deployment, whereby helps align a center in the left and right direction of the main inflatable portion generally with that of the upper body.

An occupant protection device, protecting an occupant seated in a seat, includes: a seat belt; and an airbag which is arranged in an area of a lap belt in the seat belt. The airbag includes a bag body and a regulatory tether. A thigh abutment surface abutting on a thigh of the occupant is arranged on a lower surface side of the bag body, and an upper body restraining surface restraining an upper body of the occupant is arranged on a rear surface side. The regulatory tether connects a base end to a rear surface side of an upper-lower intermediate portion of the bag body and connects a tip extending downward from the base end to the lap belt side and a length dimension is set a dimension in which a connecting portion connecting the base end of the bag body can be pulled toward the lap belt side.

An occupant protection device, which protects an occupant seated in a seat, includes: a seat belt; a front airbag device provided with a front airbag which is placed in an area of a lap belt and inflates to cover a front of the occupant when operated; and a seat airbag device provided with a seat airbag which is arranged inside a seat portion in the seat and inflates so as to raise at least a front portion side of the seat portion upward. The front airbag causes inflation gas to flow into the inside and inflates so as to protrude forward and upward when operated and a thigh abutment surface abutting on a thigh of the occupant and an upper body restraining surface restraining an upper body of the occupant are arranged on an outer peripheral surface of the front airbag when the inflation is completed.

An occupant protection device which is configured to protect an occupant seated on a seat, includes a seat belt, an airbag, and an inflator configured to supply inflation gas to the airbag. The airbag has a bag shape formed of a flexible sheet body, the airbag is folded and stored in a storage part provided in a lap belt, the airbag is inflated so as to project toward a front upper side when the inflation gas flows into the airbag, and the airbag has a substantially triangular prism shape whose axial direction is substantially aligned with a left-right direction so as to include a leg abutting surface which is capable of abutting an upper surface of a leg of the occupant and an upper body restraining surface which is capable of restraining the occupant from a chest to a head, when the airbag is completely inflated.

A seat cushion airbag apparatus includes a support portion, an airbag, and a fastening portion. The support portion is arranged below the cushion portion of a conveyance seat. The airbag is arranged between the cushion portion and the support portion and at the center portion in the width direction of the conveyance seat. The fastening portion fastens the airbag to the support portion and is disposed in the lower portion of the airbag in the inflated state at a position rearward of the center in the front-rear direction.

Seat cushion airbag apparatus
