An airbag system includes a main airbag device provided in front of an occupant and having a first bag body deployed by being inflated by a gas being supplied during input of an impact, a seat airbag device provided in a seat back of a vehicle seat and having a second bag body deployed by being inflated in an area including a front of a torso of the occupant at behind the first bag body by a gas being supplied during input of an impact, and a screen airbag device having a third bag body deployed by being inflated in an area including behind the first bag body and above the second bag body.

A curtain airbag system of a vehicle is configured such that a position of an auxiliary chamber provided in a curtain airbag is changed to correspond to an occupant's seating posture or the occupant's lying posture in response to a vehicle collision, so that the occupant is safely protected in various seating postures.

Objective: To provide a side airbag apparatus that can protect a head portion and chest portion by an appropriate restraining force, while favorably inflating and expanding even a cushion that protects a head portion and chest portion with a small inflator, and that can ensure high OOP performance.

Resolution Means: A configuration of a side airbag apparatus 100 according to the present invention includes: a bag-like cushion 110; an inflator 150; a first demarcating part 130a that demarcates the cushion 110 into a first chamber 132 on a vehicle rearward side and a second chamber 134 on a vehicle forward side, a second demarcating part 130b that demarcates a third chamber 136 on an upper side of the first chamber 132 and second chamber 134 of the cushion 110, a first inner vent 142 disposed above the first demarcating part 130, and a second inner vent 144 disposed above the second demarcating part 130b, which flows a gas flowing into the second chamber into the third chamber, and which is provided with a check valve structure that prevents a reverse flow of the gas.

The present disclosure is directed to passenger restraint system, deployable upon detection of an imminent side impact vehicle collision. The restraint system contains both an inner inflatable portion and an outer rigid telescopic portion, resulting in a semi-rigid restraint system. The restraint system may be mounted to the outboard and/or inboard sides of a vehicle seat, to protect the passenger from forces from an intruding door structure (or vehicle structure) or from other passengers. Mounting the restraint system to the vehicle seat may limit the force load that is transferred from the vehicle to the occupant, compared to a restraint system mounted to the vehicle interior.

A vehicle side airbag device including a shoulder protection part and a chest protection part that lifts an occupant's arm in a collision state while protecting the occupant's shoulder. A side airbag (1) is provided at a seat (2) and spread out in a non-inflated state, the contour on the front side in the vehicle body front-back direction has an inflection position C with a curvature change midway between the shoulder protection part X and the chest protection part Y, an upper edge line U upward and a lower edge line L downward from the inflection position. The inflection position is ahead of the shoulder protection part and above a center line F that extends lengthwise of an occupant upper arm A and divides the upper arm into upper and lower portions, and the lower edge line crosses the center line from an upper side to a lower side and positioned under the center line in a lower end position Au of the occupant upper arm.

A side airbag device for a vehicle includes a lower chamber and an upper chamber to protect a passenger from a side impact in the event of a vehicle collision. The upper chamber is bent towards the passenger by a connecting tether to support a passenger's neck region and prevent the neck from being twisted. The restraint belt forms an inserting space in front of a passenger when the upper chamber is bent so that a passenger's shoulder region is inserted into the inserting space when the passenger is moved forwards by collision inertia. The passenger's shoulder region is surrounded and supported by the restraint belt so that the passenger's body is restrained by a seat. A passenger is protected from impact and simultaneously the passenger is restrained by the seat to minimize an injury.

A seat includes a seatback including a top portion, a seat bottom coupled to the seatback, an airbag, a tether fixed to the seatback below the top portion and attached to the airbag, and an airbag extension. The airbag is inflatable from an undeployed position in the top portion to a deployed position attached to the top portion and extending in front of a front panel of the seatback. The airbag extension is inflatable from the airbag in the deployed position in front of the seat bottom.

An apparatus, system, and method for helping to protect occupants of a vehicle seat in the event of a collision. The vehicle seat includes a base with a bottom cushion, a backrest with a back cushion, and a side rest having a side cushion that extends upward from the bottom cushion and forward from the back cushion. The apparatus comprises a deployable restraint stored in a pre-deployment condition in the side rest. The deployable restraint comprising an airbag and an inflator for inflating and deploying the airbag. When inflated to a deployed condition the restrain cushions the occupant against impacts with the side rest.

The present disclosure is directed to passenger restraint system, deployable upon detection of an imminent side impact vehicle collision. The restraint system contains both an inner inflatable portion and an outer rigid telescopic portion, resulting in a semi-rigid restraint system. The restraint system may be mounted to the outboard and/or inboard sides of a vehicle seat, to protect the passenger from forces from an intruding door structure (or vehicle structure) or from other passengers. Mounting the restraint system to the vehicle seat may limit the force load that is transferred from the vehicle to the occupant, compared to a restraint system mounted to the vehicle interior.

A gas bag arrangement for a vehicle occupant restraint system of a motor vehicle comprises an inflatable gas bag which includes at least one first inflatable chamber configured to protect the head of a vehicle occupant and at least one second inflatable chamber configured to protect a shoulder and/or thorax region of the vehicle occupant, wherein the gas bag is to be arranged in or on a side of a vehicle seat facing the vehicle interior space; and at least one connecting element connected to the gas bag for connecting the gas bag to the vehicle seat or to another component of the vehicle. The connecting element is connected to the gas bag such that a partial section of the connecting element extends on a side of the gas bag which in the folded and/or inflated condition of the gas bag faces away from a vehicle occupant.
