A knee bolster assembly for a vehicle seat includes a knee bolster moveably mounted in proximity to the vehicle seat, the knee bolster selectively moveable between a first position, wherein a passenger is able to enter and exit the vehicle seat, and a second position, wherein the knee bolster is positioned directly in front of a seating surface of the vehicle seat, such that legs of a passenger seated within the vehicle seat are positioned between the seating surface of the vehicle seat and the knee bolster, the knee bolster adapted to prevent an occupant of the vehicle seat from sliding forward off the vehicle seat and restrict any hyper-extending of their lower legs due to forward inertia, and an energy absorbing device adapted to absorb energy when knees or legs of a passenger within the vehicle seat impact the knee bolster.

An airbag assembly includes an airbag having a knee chamber and an upper chamber. A wall fluidly isolates the knee chamber and the upper chamber. A sleeve extends from the knee chamber through the wall to the upper chamber and fluidly communicates the knee chamber and the upper chamber. A one-way vent is in the sleeve. The one-way vent allows for the knee chamber and the upper chamber to be maintained at different relative pressures.

Airbag cushions and related assemblies comprising improved internal tethers for reshaping deployment. In some embodiments, the assembly may comprise an inflatable cushion and an internal tether comprising an elongated axis positioned within the inflatable cushion, wherein the internal tether comprises a first concave portion attached to a first internal surface of the inflatable cushion and a second concave portion attached to a second internal surface of the inflatable cushion. The first concave portion and the second concave portion may be configured to redirect inflation of the inflatable cushion to form, upon deployment, two enlarged deployment regions and a reduced deployment region between the two enlarged deployment regions.

An airbag assembly includes an airbag cover having a first panel portion. The first panel portion has first lower edge and a plurality of clips formed at the first lower edge. The clips each have a thickness greater than the first panel portion. A case has a plurality of openings configured to receive the clips of the airbag cover. The openings in the case may each be an elongated slot including a wide portion and a contiguous narrow portion that is narrower than the thickness of the clip. Each slot is configured such that the clip can be inserted through the wide portion and then slid to the narrow portion to retain the airbag cover to the case.

A knee protection airbag device includes an airbag. When the air bag is accommodated, an occupant side wall portion and a vehicle body side wall portion are overlapped and expanded flatly and roll-folding is performed such that an upper edge side of a knee receiving portion side approaches a lower edge side of the mounting portion side, end side portions on left and right sides of the roll-folded roll folding portion are formed as folded portions which fold over a central portion near a center in a left-right direction of the roll folding portion to form a folding completed body. A joining between a first overlapping portion and a tip side part of the airbag is released when an inflation gas flows into the airbag and when a fold of a first fold is canceled and the first overlapping portion deviates from a rear area of the central portion.

An instrument panel assembly includes an instrument panel. The instrument panel assembly includes an airbag having an inboard chamber and an outboard chamber. A panel separates the inboard chamber and the outboard chamber. A diffuser is in fluid communication with both the inboard chamber and the outboard chamber. A releasable vent is between the diffuser and one of the inboard chamber and the outboard chamber. An inflator is in fluid communication with the diffuser.

A housing for a knee airbag module includes an enclosure structured to receive a knee airbag module therein, and a door rotatably coupled to the enclosure. A first securement element mounting hole is formed in the door at a location in the door structured to reside adjacent an outboard edge and a rearmost edge of the door when the door is in an open condition.

A vehicle includes a system including an instrument panel, a knee airbag, and a front airbag assembly. The knee airbag is inflatable downwardly from the instrument panel. The front airbag assembly is inflatable upwardly from the instrument panel. The front airbag assembly may be spaced from a windshield of the vehicle when the front airbag assembly is in the inflated position such that the windshield does not act as a reaction surface for the front airbag assembly, and the front airbag assembly is designed to control the kinematics of the occupant without using the windshield as a reaction surface.

In a knee-airbag-device attachment structure of a knee-airbag device, an instrument-panel-member side bracket which connects the knee-airbag device and an instrument panel member to support the knee-airbag device comprises a branch bracket which is connected to an instrument panel core. The knee-airbag-device attachment structure further comprises a vehicle-body side bracket which connects the knee-airbag device and a hinge pillar of a vehicle body.

An inflatable knee airbag having a flexible housing is disclosed. An inflatable knee airbag may provide protection for the lower anatomy of an occupant in a vehicle collision event. The disclosed inflatable knee airbag may include components, such as the inflatable airbag cushion, inflator, etc., within a flexible housing supported by a rigid or semi-rigid mounting plate. The flexible housing may conform to the shape of enclosed components, and may support and protect the enclosed components. The flexible housing may be lighter and more cost-effective than conventional housing methods.
