An occupant protection device for a vehicle includes a seat, a three-point seatbelt device, and a belt airbag device. An occupant to board the vehicle is to sit on the seat. The three-point seatbelt device includes a seatbelt extendable across a front of an upper body of the occupant sitting on the seat. The belt airbag device includes a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, and that is configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The sections are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

An occupant protection apparatus includes a seatbelt device and airbag device. The seatbelt device is capable of restraining an occupant to be seated on a seat in a vehicle. The airbag device includes an airbag casing to be disposed on or above a shoulder of the occupant. The seatbelt device includes a belt extendable through an insertion hole of the airbag casing. A fastening member is disposed in the insertion hole. The fastening member is configured to fasten the belt to the airbag casing when the belt is pulled out in a crash of the vehicle.

A system and method that comprises a plurality of inflatable tubes is provided. The plurality of inflatable tubes comprises a first tube set and a second tube set. The plurality of inflatable tubes is configured to provide a pressure distribution to an object supported by the plurality of inflatable tubes. The first tube set is configured to be inflated and deflated at a predetermined time interval to shift the pressure distribution.

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.

A protection device having a set of inflatable protection members including a neck airbag, a left lower airbag, a left upper airbag, a right lower airbag, and a right upper airbag. The protection device has a lower pocket provided with a lower base forming the neck airbag and two lower lateral branches forming the left lower airbag and the right lower airbag. An upper pocket at least partially secured to the lower pocket is provided with an upper base forming a head airbag and two upper lateral branches forming the left upper airbag and the right upper airbag. At least one longitudinal internal wall provide at least two “tubes” in each upper airbag, the upper pocket being in fluid flow communication with the lower pocket.

A vehicle seat is rotatable about an axis perpendicular to a vehicle floor from a forward-facing position to a rear-facing position. The seat includes a seat bottom and a seat back. A seat belt assembly extends at least partially from the seat back. At least one airbag is incorporated into the seat belt assembly and is deployable when the vehicle seat is rotated to at least one of the rear-facing position and a position between the forward-facing position and the rear-facing position.
