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 adaptive force vehicle airbag (AFVA) system includes airbag(s) stowed in a compressed state within an interior of a vehicle. An impact sensor detects a change in motion of the vehicle indicative of a collision. Selectable force gas generator(s) (SFGGs) gas-generating propellant cells that are individually fired. The SFGGs have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate at least one of the airbag(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the SFGGs. The controller enables the AFVA system to: (i) receive an inflation signal from the impact sensor; and (ii) fire a selected number of the gas-generating propellant cells to at least partially inflate the at least one airbag.

A vehicle airbag system is proposed. The vehicle airbag system includes: a front airbag mounted to a portion of a vehicle in front of a passenger and configured to be unfolded toward a front of the passenger; an upper airbag mounted to a portion of the vehicle above the passenger and configured to be unfolded toward the front of the passenger; a seat detector configured to detect a seating posture of the passenger; and a controller configured to control unfolding of the front airbag or the upper airbag on the basis of the passenger's seating posture detected by the seat detector.

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 a 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.

In a vehicle occupant protection system, a gas generator assembly (12) comprises at least one separate support (24) mountable to the vehicle and at least two gas generators (16, 18) which are tightly mounted on the support (24). A control unit (22) determines the times of activation of the at least two gas generators (16, 18) simultaneously or time-delayed in order to be able to activate one of the gas generators (16, 18) already in advance of a possibly imminent crash situation so that the airbag (14) is filled in such a way that it starts an interaction with an associated vehicle occupant which moves the vehicle occupant by a predetermined distance.

A curtain airbag apparatus which can smoothly expand an airbag cushion even with a low gas ejection pressure of an inflator. A curtain airbag apparatus according to an embodiment includes: an outer cushion provided on an upper side of a pillar constituting a vehicle along a forward and backward direction of the vehicle to be expandable; a plurality of inner cushions which are fixed to an inner side of the outer cushion along the forward and backward direction of the vehicle to be spaced apart from each other and are independently expandable; and inflators disposed in the plurality of inner cushions, respectively, so as to eject gas into the inner cushions so that the inner cushions are expanded by generation of the gas.

One general aspect includes a system to establish a deployment force for an airbag of a vehicle, the system includes: a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to carry out the following steps: monitoring a head position of a vehicle occupant; based on the monitored head position, calculating a distance of a body part of a vehicle operator relative to a portion of an interior cabin of the vehicle; and based on the distance of the body part, establishing the deployment force for the airbag.

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 vehicle airbag system is proposed, The vehicle airbag system includes: a front airbag mounted to a portion of a vehicle at front of a passenger and configured to be unfolded toward front of the passenger; an upper airbag mounted to a portion of the vehicle above the passenger and configured to be unfolded toward front of the passenger; a seat detector configured to detect a seating posture of the passenger; and a controller configured to control unfolding of the front airbag or the upper airbag on the basis of the passenger's seating posture detected by the seat detector.

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.
