A restraint system includes a side curtain airbag including an inboard panel, an outboard panel, and a perimeter at which the inboard panel and the outboard panel are connected to each other. The side curtain airbag includes a main portion formed of part of the inboard panel and part of the outboard panel, and a folded-over portion formed of part of the inboard panel and part of the outboard panel. The main portion and the folded-over portion each include a dead zone spaced from the perimeter at which the inboard panel and the outboard panel are connected to each other. The side curtain airbag is folded so that the inboard panel of the folded-over portion abuts the inboard panel of the main portion. The main portion and the folded-over portion are attached to each other via the respective dead zones.

A roof airbag for a vehicle. The roof airbag includes: a main cushion located at a roof panel of the vehicle and configured to be unfolded from a first side portion to a second side portion of the roof panel when being operated; a sub cushion coupled to a side surface of the extended main cushion and unfolded outside the main cushion; and an inflator located at the roof panel of the vehicle and connected to the main cushion or the sub cushion, and configured to inject gas into the main cushion and the sub cushion to unfold the main cushion and the sub cushion.

There is provided a passenger seat air bag having a portion which is unfolded to a side toward a center side of a vehicle in which a pressure difference in the portion is suppressed. A passenger seat air bag includes a front unfolding portion which is unfolded in front of the passenger seat, and a side unfolding portion which is in communication with the front unfolding portion and which is unfolded to side, of the passenger seat, nearer to a center of the vehicle. A horizontal tether is provided in the side unfolding portion in an arrangement which is approximately horizontal during unfolding. When unfolding gas is injected from the front to the air bag, because the horizontal tether does not block flow of the unfolding gas, pressure us the side unfolding portion is made uniform.

A front passenger seat airbag includes an attachment portion provided on a front end side when inflation has been completed, an occupant protection portion provided on a rear end side to protect the occupant when inflation has been completed, and a cavity portion formed at an intermediate portion between the attachment portion and the occupant protection portion in a manner of penetrating the front passenger seat airbag substantially along a left-right direction. A left edge side and/or a right edge side of the occupant protection portion when inflation has been completed is formed with a protruding region protruding rearward and outward with respect to a central region. At least one of upper and lower edges of an occupant side panel is coupled to an end of the peripheral wall panel. An outer peripheral panel portion of the panel portion is a concave portion in a flatly deployed state.

A side airbag of a vehicle occupant restraint system (10) which is provided to be mounted on a vehicle seat (14) comprises an inflatable head gas cushion (18) and an inflatable torso gas cushion (20) connected to the head gas cushion (18) both of which form separate inflatable compartments of the side airbag (12). The head gas cushion (18) and the torso gas cushion (20) are formed by separate inflatable cushions which are fastened to each other in a connecting section (22). In a vehicle occupant restraint system, the side airbag (12) is mounted on a vehicle seat (14) of a vehicle on the side facing a passenger seat (16) of the vehicle.

A torso stabilization restraint configured to restrain a user in a seat, includes an inflatable first module, an inflatable second module, an inflatable third module, and connectors arranged on one or more of the modules. The connectors are configured to reversibly connect a) the first module and the second module, and b) the second module and the third module when the first, second, and third modules are inflated. When the first, second, and third modules are inflated and connected, the torso stabilization restraint and the seat combine to exert radially inward directed pressure on a torso of the user. The first and second modules are deployable from a seat. The second module is deployable from a seat belt, is arranged between the first and second modules, and is configured to couple to the first and second modules when the modules are inflated.

It is provided a gas bag for a vehicle occupant restraint system of a motor vehicle, comprising at least one first inflatable chamber configured for the protection of the head of a vehicle occupant; at least one second inflatable chamber configured for the protection of 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. The first and the second chamber are rotatable relative to each other in the inflated condition of the gas bag.

A restraint system (10) for helping to protect an occupant (60) of a vehicle (20) having a roof (32) and a cabin (40) with a seat (50) for the occupant (60) includes an airbag (120) having a stored condition within the roof (32) and being inflatable to deployed condition extending into the cabin (40) aligned with the seat (50). A tether (140) includes a first end (142) connected to the airbag (120) and a second end (144) connected to the vehicle (20). Tear stitching (170) interconnects overlying portions (152, 154) of the tether (140). The tear stitching (170) is rupturable in response to occupant (60) penetration into the deployed airbag (120) to permit the interconnected overlying portions (151, 154) to move relative to one another such that the tether (140) lengthens.

A cushion of an airbag apparatus may include: a rear panel having a gas inlet formed at the rear thereof, and a first connecting end formed along the edge thereof and deployed forward when gas is introduced into a primary filling room open to the front; and a front panel having a second connecting end formed along the edge thereof at the front of the rear panel and coupled to the first connecting end, and a passenger support region which is formed at the front surface thereof and deployed forward when gas is introduced into a secondary filling room open to the rear.
