In severe traffic accidents, crumpling the front of the car causes the passenger's leg get stuck between the seat and the car's dashboard. In this article, the condition of the seat and occupant safety sack is checked, which keeps the passenger in place, in heavy crashes, then raises the occupant's knee, and pulls the front seats back as far as possible.

An assembly includes a seat bottom, a rear bladder, a front bladder, and a check valve. The seat bottom includes a rear seat cushion and a front seat cushion in a seat-forward direction from the rear seat cushion. At least one of the rear seat cushion or the front seat cushion is vertically movable relative to the other one of the rear seat cushion or the front seat cushion. The rear bladder supports the rear seat cushion. The front bladder supports the front seat cushion. The check valve fluidly connects the front bladder and the rear bladder. The check valve is oriented to permit fluid to pass from the rear bladder to the front bladder and block fluid from passing from the front bladder to the rear bladder.

An airbag assembly includes a first airbag and a second airbag each inflatable to an inflated position, and a panel. In the inflated position, each of the first and second airbags have a bend, and first and second legs extending from the bend. The panel extends from the first airbag to the second airbag in the inflated position.

Airbag cushion assemblies for aspirating ambient air to enhance inflation. Some embodiments may comprise an inflation module comprising an inflator and a plurality of inflation nozzles fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into an airbag cushion. A housing coupled to the airbag cushion may comprise an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion. The plurality of inflation nozzles may be configured to, upon actuation of the inflator, draw ambient air into the airbag cushion along with the inflation gas from the inflator. In some embodiments, a valve assembly may be positioned below the inflation nozzles and may be configured to automatically open upon actuation of the inflator and to automatically close during or following inflation of the airbag cushion.

A gas generator includes, an ignition device chamber arranged on a first end side of a cylindrical housing and closed by an ignition device including an igniter, a diffuser including a gas discharge port and closing a second end side of the cylindrical housing opposite to the first end in an axial direction, a compressed gas containing chamber disposed between the diffuser and the ignition device chamber and containing therein a compressed gas as a gas source, a first rupturable plate disposed closing off the ignition device chamber and the compressed gas containing chamber from one another, and a second rupturable plate disposed closing off the compressed gas containing chamber and the diffuser from one another, a cup-shaped deflector disposed on a side of the second rupturable plate where the compressed gas containing chamber is disposed, the cup-shaped deflector including a gas passage in a peripheral surface section thereof and a fragile section on at least one of a bottom surface section thereof and the peripheral surface section, and being disposed with the bottom surface section located on a side where the first rupturable plate is disposed, with an opening covering the second rupturable plate, and with a cylindrical gap defined between the peripheral surface section and an inner peripheral wall surface of the cylindrical housing.

A motor vehicle seat with an integrated child seat, the child seat comprising inflatable chambers that can be brought from a compressed The child seat includes air chambers that are inflatable in multiple, e.g., three, stages, and which are fixed, e.g., adhesively bonded or stitched, to the surface of the motor vehicle seat.

A side airbag device may include: an inflator mounted to a seat frame; a cushion covering the inflator and configured to be deployed by gas discharged from the inflator to protect a side portion of an passenger; and a tether mounted to the inflator and configured to enclose the cushion and reduce collision energy applied to the passenger.
