The present invention relates to an airbag intended for retaining the knees of the occupants of automotive vehicles during a collision consisting of an inflatable cushion ( 11 ), a gas generator ( 7 ) providing the gas for inflating the cushion, a diffuser tube ( 9 ) connected to the gas generator ( 7 ) which is fixed to the inflatable cushion ( 11 ) along one of its sides, a metal housing ( 13, 39 ) for supporting the airbag assembly and fixing it to the vehicle and a protective cover ( 15, 17, 35 ) in which the cushion is folded such that a part remains deployed in the Y direction. The airbag has a reduced volume, is easily integrated in the automobile structure and can be very quickly positioned in the event of a collision without the risk of it being able to deploy between the knees of the occupant.
