A roof airbag arrangement includes an airbag, first and second guide rails, at least one first sliding member and at least one second sliding member. The airbag longitudinally extends along a length between first and second longitudinal sides and laterally extending along a width between first and second lateral sides. The first and second guide rails are on laterally opposite sides of the airbag, and define first and second channels, respectively. The at least one first sliding member is mounted within the first guide rail for translation within the first channel. The at least one second sliding member is mounted within the second guide rail for translation within the second channel. First and second pluralities of tethers connect the first lateral side of the airbag with the at least one first sliding member and the second lateral side of the airbag with the at least one second sliding member, respectively.

In one aspect, an apparatus for helping to protect an occupant of a vehicle includes a frontal curtain airbag. The airbag has overlying panels that are interconnected. The airbag is deployable a deployed condition in which the airbag spans across a width of a windshield opening of the vehicle. A restraining panel is separate from and extends widthwise over the panels of the airbag. The restraining panel is connected to the airbag and has a width configured to cause opposing end portions of the deployed airbag to be bent toward one another and into a curved configuration. Pressurization in the deploying airbag tensions the restraining panel widthwise. The tensioned restraining panel maintains the bend in the deploying airbag so that an effective airbag depth is measured between the restraining panel and the airbag.

The present invention relates to a seat airbag apparatus for a vehicle, in which a raw cushion fabric 210 provided in the form of a single flat panel is coupled by sewing to an inner cushion part 110 provided in the form of a flat panel, and a front cushion 200 is formed by using the raw cushion fabric 210 provided in the form of a flat panel. Therefore, the sewing coupling may be easily and smoothly performed, and particularly the tolerance in respect to the sewing coupling may be reduced, thereby improving quality.

A roof mounted airbag is proposed. The roof mounted airbag includes: a fixed chamber having an upper portion fixed to a roof of a vehicle and configured to be expanded downward when gas is supplied into the fixed chamber; a first separated chamber connected to the fixed chamber, having an inside that communicates with an inside of the fixed chamber to be supplied with the gas from the fixed chamber, and configured to be expanded downward when the gas is supplied into the first separated chamber; and a second separated chamber connected to the fixed chamber while being spaced apart from the first separated chamber, having an inside that communicates with the inside of the fixed chamber to be supplied with the gas from the fixed chamber, and configured to be expanded downward when the gas is supplied into second separated chamber.

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 center airbag apparatus may include: an inflator mounted in an instrument panel and configured to inject gas; a first cushion part deployed by the gas injected from the inflator, and configured to support a driver airbag; and a second cushion part connected to the first cushion part, and configured to be deployed between the driver airbag and a passenger airbag to protrude toward the rear of a vehicle based on the driver airbag.

A center airbag apparatus may include: an inflator mounted in an instrument panel and configured to inject gas; a first cushion part deployed by the gas injected from the inflator, and configured to support a driver airbag; and a second cushion part connected to the first cushion part, and configured to be deployed between the driver airbag and a passenger airbag to protrude toward the rear of a vehicle based on the driver airbag.

A curtain airbag includes: an airbag body of which an upper periphery is fixedly mounted on a body side of the vehicle to be deployable downward to cover an inboard side of the window when an inflation gas flows in; and a connection belt connecting the window and the airbag body, wherein: the connection belt is arranged so as to cover a portion of an end periphery of the airbag body in the front and rear direction and an inflatable portion of the airbag body on an outboard side wall side of the airbag body in a proper arrangement state; and a mark for checking the proper arrangement state of the connection belt is arranged to be visually recognized from at least the outboard side wall side in a vicinity of each of an upper periphery and a lower periphery of the connection belt in the proper arrangement state.

A side airbag apparatus includes an inflator, an airbag having a main inflation portion and an auxiliary inflation portion, and a restriction portion. The main inflation portion is configured to be inflated by inflation gas supplied from the inflator and deployed forward in a space between a side wail of the vehicle and an occupant seated in a normal posture in a vehicle seat. The auxiliary inflation portion is configured to be inflated in a seat back by the inflation gas from the inflator, thereby pushing the occupant toward an inner side of the vehicle. The restriction portion restricts the auxiliary inflation portion from being inflated toward a gap that is between the rear end section in the outer side portion of the seat back and the rear end section in the middle portion of the seat back.

The present invention relates to a seat airbag for a vehicle in which a side cushion 100 is deployed to protrude forward from a seatback 10 and protects the side of a passenger 20, a front cushion 200 is deployed to protrude from the side cushion 100 to the front of the passenger 20 and protects the front of the passenger 20, an upper tether 300 and a lower tether 400 exhibiting strong restraint force are connected to the side cushion 100 and the front cushion 200. Thus, it is possible to effectively restrain the passenger's lateral behavior, forward behavior, and diagonal behavior, thereby further enhancing the passenger's protective effect.
