A gas distribution system for airbag inflation in a vehicle can include: a passenger airbag including a plurality of inflatable chambers; an airbag inflation device configured to produce a gas when a collision involving the vehicle is sensed and to supply the gas to the passenger airbag, causing deployment of the passenger airbag; and an inflation gas distributor disposed at least partially between the airbag inflation device and the passenger airbag, the inflation gas distributor including a rotatable distributor belt, the inflation gas distributor configured to allow passage of the gas from the airbag inflation device to a first subset of the plurality of chambers, and to impede passage of the gas from the airbag inflation device to a second subset of the plurality of chambers, by rotating the distributor belt to a gas distribution position selected among a plurality of predetermined gas distribution positions.

There is proposed a vehicle seat configured to support an occupant (42) in a sitting position, the seat comprising: a squab (27), a backrest (28), and an airbag unit. The airbag unit comprises an inflatable airbag (1) provided in an initially rolled and/or folded airbag package (33), and an inflator (34) actuable to direct inflating gas into the airbag (1) to inflate the airbag into an inflated configuration. The airbag (1) comprises a pair of inflatable chambers (8, 9) which are physically connected to one another via a connecting interface (17), and are fluidly isolated from one another. The airbag unit is mounted and configured such that, upon actuation of said inflator (34) to inflate the airbag (1), said inflatable chambers (8, 9) inflate into respective deployed positions in which they: i) extend forwardly from respective opposing and laterally spaced-apart side regions of said backrest (28); and ii) extend upwardly, and laterally inwardly across an uppermost region of the seat towards said connecting interface (17), so as to thereby cooperate to define an inflated shroud around at least an uppermost region of the backrest (28) so as to extend over said sitting position and provide lateral protection to a said occupant (42) of the seat in said sitting position.

A restraint system (10) for helping to protect an occupant (60) of a vehicle (20) having a roof (32) and a cabin (40) including a seat (50) for the occupant (60) has an airbag (70). The airbag (70) has a stored condition within the roof (32) and is inflatable to a deployed condition extending into the cabin (40) and aligned with the seat (50). The airbag (70) includes a first portion (94) defining a first chamber (100) and a second portion (104) defining a second chamber (110). The first portion (94) is connected to the vehicle (20) and includes a vent (106). The first portion (94), in response to occupant (60) penetration with the second portion (104), vents inflation fluid from the vent (106) and elongates to enable folding of the airbag (70) away from the occupant (60).

A restraint system (10) for helping to protect an occupant (60) of a vehicle (20) having a seat (50) for the occupant (60) includes a primary airbag (70) having a stored condition within a roof (32) and being inflatable to a deployed condition aligned with the seat (50). A support airbag (76) has a stored condition within the roof (32) and is inflatable to a deployed condition engaging the primary airbag (70).

A restraint system for helping to protect an occupant (60) of a vehicle (20) includes a first inflator (74) for providing inflation fluid at a first fluid pressure and a second inflator (76) for providing inflation fluid at a second fluid pressure greater than the first fluid pressure. An airbag (70) includes a stored condition within a roof (32) and is inflatable to a deployed condition extending into a cabin (40) and aligned with a seat (50) for the occupant (60). The airbag (70) includes a first portion (98) defining a first chamber (100) fluidly connected to the first inflator (74) and a second portion (102) defining a second chamber (104) fluidly connected to the second inflator (76) and fluidly isolated from the first chamber (100). The first portion (98) moves relative to the second portion (102) in response to occupant (60) penetration into the airbag (70).

A gas distribution system for airbag inflation in a vehicle can include: a passenger airbag including a plurality of inflatable chambers; an airbag inflation device configured to produce a gas when a collision involving the vehicle is sensed and to supply the gas to the passenger airbag, causing deployment of the passenger airbag; and an inflation gas distributor disposed at least partially between the airbag inflation device and the passenger airbag, the inflation gas distributor including a rotatable distributor belt, the inflation gas distributor configured to allow passage of the gas from the airbag inflation device to a first subset of the plurality of chambers, and to impede passage of the gas from the airbag inflation device to a second subset of the plurality of chambers, by rotating the distributor belt to a gas distribution position selected among a plurality of predetermined gas distribution positions.

An assembly includes a front console having an outer surface and a pair of outboard ends spaced along an axis and defining a center therebetween. The assembly includes an airbag supported by the front console at one of the outboard ends and inflatable from an uninflated position elongated transverse to the axis to an inflated position extending along the outer surface toward the center.

An occupant protection system for a vehicle may include an expandable curtain and/or an expandable bladder configured to be expanded from a stowed state to a deployed state. The system may also include a transverse ceiling trim panel and one or more side ceiling trim panels configured to be coupled to a ceiling of the vehicle, with the transverse ceiling trim panel extending substantially transversely with respect to the one or more side ceiling trim panels. Portions of the ceiling trim panels may be configured to deflect and allow expansion of the expandable curtain and/or the expandable bladder to the deployed state. The system may also include a deployment controller and one or more inflators configured to cause deployment of the expandable curtain at a first time and deployment of the expandable bladder at a second time after the first time.

An air-bag apparatus includes: a bag body that is provided on a vehicle seat and that is inflated and expanded at a time of an impact input and prevents at least an upper part of a body of an occupant seated on the vehicle seat from being separated from a seat back of the vehicle seat; an inflator that supplies a gas to the bag body at a time of an impact input; a body size detection part that detects a body size of the occupant seated on the vehicle seat; and an expansion degree adjustment part that adjusts a degree of an inflation expansion of the bag body in accordance with the body size of the occupant detected by the body size detection part.

An assembly includes a seatback having an upright frame member and a side airbag mounted to the upright frame member. The side airbag is inflatable to an inflated position. The side airbag includes a forward chamber and a spacer chamber adjacent each other and substantially fluidly separated from each other in the inflated position. At least one inflator is in fluid communication with the forward chamber and the spacer chamber.
