Abstract: There is provided an occupant protection device for protecting an occupant seated on a seat, including: an airbag folded and accommodated in a bag shape made of a flexible sheet material; and a holding belt portion that is wrapped around a hip of the occupant and holds the folded airbag. The airbag is configured to, when the airbag is activated, allow an inflation gas to flow thereinto, and inflate to protrude forward and upward from the holding belt portion, and includes an upper body restraining surface capable of restraining an upper body of the occupant, on a rear surface side, when inflation is completed, and a vehicle body side member abutting surface that abuts against a vehicle body side member provided in front of the seat to be capable of ensuring a reaction force of the airbag when the occupant is restrained, on a front surface side.

Abstract: 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.

Abstract: An occupant protection device, which protects an occupant seated in a seat, includes: an airbag; and a holder configured to accommodate and hold the folded airbag. The holder is arranged in front of a waist of the occupant seated on the seat. The airbag inflows inflation gas into the inside and inflates so as to protrude from the holder and toward the occupant side, the airbag including: a lower inflation portion configured to cover an upper surface of the thigh; an upper inflation portion which configured to cover a front surface of an upper body; and a cross-inflation portion arranged between the lower inflation portion and the upper inflation portion. A length dimension of the holder is set to a dimension which secures a space for arranging the inflated cross-inflation portion between the waist and the holder when the inflation of the airbag is completed.

Abstract: 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.

Abstract: 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.
