A seat for a vehicle includes an occupant protection system. The occupant protection system includes an airbag or other barrier that at least partially occludes an opening to a volume under a vehicle seat. The occupant protection system may reduce or prevent lower leg injury and/or retain cargo in the volume during a collision event.

System, methods, and other embodiments described herein relate to isolating a compartment. In one embodiment, a method includes isolating airflow to an occupant by actuation of a partition in response to a signal indicating a risk and the partition utilizes an inflatable bladder to seal an area of a compartment in a vehicle. The method also includes communicating a precaution associated with the actuation to occupants.

A computer-implemented method for checking the correct deployment of an airbag device comprises, in a vehicle or test vehicle model, optionally arranging a dummy or model of a vehicle occupant in the vicinity of the airbag device, triggering the deployment of the air chamber of the airbag device, taking at least one image of a scene including the air chamber at a plurality of discrete times following the triggering of its deployment and verifying the volume of inflation and/or deployment of the air chamber at the plurality of discrete times following the triggering of its deployment on the basis of the at least one image.

An airbag device of a vehicle and a control method thereof. The airbag device of a vehicle includes a detection unit configured to detect collision information of a vehicle and seating state information of an occupant, an airbag unit including a plurality of airbag modules, each of the airbag modules being configured to be inflated from a contracted state as working gas is supplied and to be restored to the contracted state as the working gas is discharged, a valve unit configured to regulate the working gas supplied to the airbag unit, and a control unit configured to determine a hitting position based on the collision information and the seating state information, and to control the valve unit to supply the working gas to a target airbag module installed at the hitting position, thereby inflating the target airbag module.

For example, even when an occupant is seated offset in a left-right direction, an airbag is reliably expanded and deployed. An airbag device contains: an airbag that protects at least a side portion of a shoulder region, upper arm region, and chest region of an occupant seated on a vehicle seat; and an inflator that supplies gas to the airbag. The airbag has a pair of side part protection chambers that are housed on at least both left and right sides of the vehicle seat. The side part protection chambers, when expanded and deployed, expand and deploy forward independently from both left and right sides of the vehicle seat. A pair of the inflators are provided to allow gas to be supplied to each side part protection chamber, and the ignition timing of the inflators can be controlled separately.

A vehicle seat includes a seat back frame, an elastic installation supporting member installed in the seat back frame, and an airbag within a seat back, the vehicle seat causing the airbag to inflate and develop within the seat back. An inflator is attached to the seat back frame. The seat back frame has a substantially frame shape along a seat back shape. The airbag is provided in the seat back frame in the substantially frame shape. The inflator is attached to at least one of an upper portion and a lower portion of the seat back frame in the substantially frame shape. An inflation and a development of the airbag in the seat back due to an operation of the inflator allows the airbag to elastically support an upper body of a seated person and to elastically receive an impact force.

Provided is a vehicle seat that is rotatable relative to a vehicle body and can prevent a collision between an object located around a seat body and an occupant by airbags. A vehicle seat includes: a seat body (6) supported by a vehicle body (2b) so as to be rotatable around a substantially vertical axis; a pair of airbags (17) provided on either lateral side edge of the seat body and configured to deploy to respective lateral sides of an occupant seated on the seat body; a rotation angle detecting device (15) provided on the seat body and configured to detect a rotation angle of the seat body relative to the vehicle body; and a control device (22) configured to control deploying operation of the respective airbags independently of each other. The deploying operation includes a deploying amount and/or a deploying timing. The control device is configured to individually control the deploying operation of the pair of airbags according to the rotation angle detected by the rotation angle detecting device.

An airbag device of a vehicle and a control method thereof. The airbag device of a vehicle includes a detection unit configured to detect collision information of a vehicle and seating state information of an occupant, an airbag unit including a plurality of airbag modules, each of the airbag modules being configured to be inflated from a contracted state as working gas is supplied and to be restored to the contracted state as the working gas is discharged, a valve unit configured to regulate the working gas supplied to the airbag unit, and a control unit configured to determine a hitting position based on the collision information and the seating state information, and to control the valve unit to supply the working gas to a target airbag module installed at the hitting position, thereby inflating the target airbag module.

A seat includes a seat bottom and a seatback supported by the seat bottom. The seatback is pivotable relative to the seat bottom. The seatback includes a front defining an occupant seating area. An airbag is supported by the seatback and is inflatable to an inflated position. The airbag extends from the front into the occupant seating area in the inflated position. A computer has a processor and a memory storing instructions executable by the processor to control inflation of the airbag based on an angle of the seatback relative to the seat bottom.

A side airbag apparatus may include: a seat on which a passenger is seated; an inflator mounted on the seat, and configured to jet gas; a cushion inflated by the gas jetted from the inflator, and deployed toward the passenger so as to move the passenger to an inboard side of the vehicle; and a controller configured to operate the inflator to deploy the cushion before the collision of the vehicle, according to driving information of the vehicle, based on a signal of a sensor mounted on the vehicle.
