A vehicle occupant restraint device comprises a knee airbag (10) deployable between an instrument panel (32) and the legs of a vehicle occupant and including an airbag sheath (14) and at least one exhaust orifice (18) formed therein. The vehicle occupant restraint device further comprises a means for qualifying the build of the vehicle occupant, an activating unit (24) for selectively releasing the exhaust orifice (18) and a control means which actuates the activating unit (24) depending on the qualification of the build of the vehicle occupant. A method for protecting a vehicle occupant comprises the following steps of: qualifying the build of the vehicle occupant; inflating a knee airbag (10) deployable between an Instrument panel (32) and the legs of a vehicle occupant and including an airbag sheath (14) and at least one exhaust orifice (18) formed therein with gas; and adapting the gas exhaust behavior in that an activating unit (24) is actuated for releasing the exhaust orifice (18) depending on the qualification of the build of the vehicle occupant.
