A knee airbag module for a vehicle includes an airbag housing configured to be mounted in an instrument panel of the vehicle at a position above a glove box of the instrument panel. The module also includes a knee airbag comprising overlying panels interconnected along a perimeter connection to define an inflatable volume of the knee airbag. The knee airbag has a stored condition in the airbag housing and is configured to inflate and deploy in a direction that is downward and forward into a footwell of the vehicle.

Knee airbag

A knee airbag includes overlying panels interconnected along a perimeter connection to define an inflatable volume of the knee airbag. The knee airbag includes a filling portion and a cushion portion. The filling portion is configured to receive inflation fluid from an inflator and to direct the inflation fluid from the inflator to the cushion portion. The cushion portion has a width that is greater than a width of the filling portion and extends laterally beyond the width of the filling portion on opposite sides of the filling portion. The knee airbag also includes at least one tether having a first end connected to the cushion portion and an opposite second having a connection configured to anchor the at least one tether. The at least one tether is configured to limit movement of the cushion portion and to help position the cushion portion relative to a vehicle surface for which the knee airbag is configured to help prevent impacts from a vehicle occupant.

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.
