Patent attributes
A knee airbag arrangement for a vehicle. The knee airbag arrangement includes an inflatable airbag and an external tether. The airbag is adapted to be inflated to a position between an instrument panel of the vehicle and a knee/shin region of a vehicle occupant. The knee airbag is adapted to form a first deployment mode or a second deployment mode when in a deployed state. The external tether controls deployment of the airbag to the second deployment mode. The depth (D2) of the airbag in the second deployment mode is greater than a depth (D1) of the knee airbag in the first deployment mode. A depth of the airbag in a deployed state is a greatest extent of the airbag perpendicular to the instrument panel in the knee/shin region.
