An instrument-panel assembly for a vehicle includes an instrument panel. The instrument-panel assembly includes a steering column adjacent to the instrument panel. The instrument-panel assembly includes an airbag mounted to the instrument panel below the steering column. The airbag is inflatable to an inflated position below the steering column. The airbag defines a knee cavity in the inflated position. The airbag in the inflated position has a knee-forward panel vehicle-forward of the knee cavity; a first wing and a second wing that extends vehicle-rearward from the knee-forward panel on opposite sides of the knee cavity; and a top panel that extends vehicle-rearward from the knee-forward panel and extends from the first wing to the second wing above the knee cavity.

A knee airbag device including an airbag cushion, a storage case in which is formed a horizontally long opening part where the expanded and deployed airbag cushion pops outs, a first flap for covering the airbag cushion exposed through the opening part such that the airbag cushion is retained in the storage case, and having a first weak part that breaks when pressed by the airbag cushion during expansion and deployment and a second flap, which is a component with a larger dimension in a length direction than the first flap and for covering an outer surface of the first flap so as to transverse in a short direction of the opening part a center part of the airbag cushion in a lateral direction, the second flap having a second weak part that breaks when pressed by the airbag cushion after rupture of the first weak part.

A knee airbag includes a cushion portion, which includes overlying panels interconnected along a perimeter connection to define an inflatable volume of the knee airbag. The panels are interconnected within the perimeter connection along one or more interior connections that define inflatable chambers within the inflatable volume. The knee airbag also includes a tether connected to an exterior surface of the cushion portion at spaced locations. The tether has a length that is shorter than the distance between the locations on the cushion portion to which the tether is connected. The tether is configured to become tensioned in response to inflation of the cushion portion and causing a bend to form in the cushion portion.

A knee protection airbag device includes an airbag, an inflator, an airbag cover, and an attachment base which holds those and is to be attached to a vehicle body member. The attachment base includes a holding seat which is disposed in front of a body portion of the inflator and a folded portion of the airbag, and holds the body portion and the airbag attached by a fastening bolt of the inflator, and attachment seats which are arranged on left and right sides of the holding seat and are attached to the vehicle body member. The airbag cover covers a vicinity of the airbag folded and the body portion of the inflator on a rear side of the attachment base, is attached to the attachment base due to the fastening bolt being fastened, and provides a projection opening on a bottom side of the airbag cover.

A knee airbag module includes an inflatable knee airbag, an inflator for inflating the knee airbag, a housing for supporting the knee airbag and inflator, a cover for enclosing the knee airbag in the housing, and a deployment flap positioned beneath the cover. The housing includes an opening through which the knee airbag deploys. The deployment flap is connected to the housing and spans across at least a portion of the opening. The knee airbag has a width that extends laterally beyond the lateral extent of the housing when the airbag is deployed. The knee airbag also includes a central portion that spans the width of the housing when the knee airbag is deployed. The deployment flap is configured to initially inhibit deployment of the central portion of the knee airbag while remaining portions of the knee airbag initially deploy. The deployment flap is configured to thereafter rupture and permit deployment of the central portion.

A knee airbag for a vehicle occupant restraint device can adopt a deployed position of use between a fixed vehicle component and the legs of a vehicle occupant. The airbag includes an airbag sheath, at least one exhaust orifice formed therein and control features for selectively releasing the exhaust orifice. The control features are disposed inside the knee airbag and arranged so as to release or block the exhaust orifice depending on the expansion of the knee airbag in a particular direction of expansion.

A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising an inflator and an inflatable cushion comprising a lower portion, an upper portion and an external tether connecting the lower portion and the upper portion. The inflator provides inflation gas to the inflatable cushion and the inflatable cushion is configured to deploy forward of an occupant seated in a rear seat of a vehicle by curving away from the occupant. The external tether is configured to control a trajectory of the deployment of the inflatable cushion by pulling the upper portion toward the lower portion to curve the inflatable cushion such that the upper portion is located above the lower portion.

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 air bag apparatus having a housing disposed in or adjoining a lower region of an instrument panel extending from front to rear having an outlet opening. An inflator and a knee air bag are mounted in the housing in the initial state, and in an expanded state deploys in front of the instrument panel. The air bag outer skin has a protective section and a fill and support section. The protective section when expanded state is positioned, in front of the instrument panel. To improve deployment behavior, the fill and support section features a vehicle-front section such that with the knee air bag fully expanded, the front section extends beyond the vehicle front end of the housing in the direction of the vehicle front.

An assembly for a vehicle includes a vehicle body having a body side. A seat is adjacent the body side. The seat includes a seatback and a seat bottom extending in a seat-forward direction from the seatback. The seatback and seat bottom defines an occupant-seating area. A head airbag is mounted to the seatback and is inflatable over the occupant-seating area. A knee airbag is mounted to the body side. The knee airbag is inflatable from the body side to an inflated position. The knee airbag in the inflated position is adjacent to the seat bottom in the seat-forward direction from the seat bottom.
