Abstract
An airbag module is shown for an occupant restraint system of a motor vehicle. The airbag module has a housing in which a folded inflatable airbag is accommodated. A part of the housing is designed as a covering which is movable into the vehicle interior and which supports the knees of the occupant during the unfolding of the airbag. The airbag is designed in such a manner that it can be unfolded through an opening at the housing past the covering and into the vehicle interior when the covering is at least partly moved into the vehicle interior.

7. An apparatus for restraining an occupant of a vehicle, comprising:
-
a housing for mounting within a cavity below a portion of a dashboard of the vehicle, said housing comprising;
a rear wall being fixedly secured within said cavity;
a lower wall depending away from said rear wall; and
a flap being pivotally secured to said lower wall for movement between a first position and a second position, said flap being in a spatial relationship with respect to said rear wall when said flap is in said first position and said flap being in a further spatial relationship with respect to said rear wall when said flap moves towards said second position; and
an interior volume being defined by said rear wall, said lower wall and said flap;
an airbag being configured and dimensioned to be stored and received within said interior volume when said airbag is in an uninflated state and said airbag being configured, dimensioned and positioned to extend outwardly from said cavity and restrain the occupant when said airbag is in an inflated state;
an exterior flap having an inner surface and an outer surface, said inner surface of said exterior flap is fixedly secured to said flap, said exterior flap being pivotally secured to said dashboard at a point of securement for movement between an unrestraining position and a restraining position, said exterior flap covering said cavity and said housing when said exterior flap is in said un-restraining position and said exterior flap opens along all sides except for said point of securement to make contact with a portion of the occupant when said exterior flap is in said restraining position; and
an inflator for inflating said airbag, said airbag causing said flap to pivot from said first position to said second position and said exterior flap pivots from said un-restraining position to said restraining position as said inflator inflates said airbag. - View Dependent Claims (8, 9, 10, 11, 16)

12. An apparatus for restraining an occupant of a vehicle having a dashboard, comprising:
-
a housing being pivotally secured to a portion of the dashboard of the vehicle for movement between an open position and a closed position, said housing comprising;
a rear wall;
a lower wall depending away from said rear wall; and
a flap being pivotally secured to said lower wall for movement between a first position and a second position, said flap being in a spatial relationship with respect to said rear wall when said flap is in said first position and said flap being in a further spatial relationship with respect to said rear wall when said flap moves towards said second position; and
an interior volume being defined by said rear wall, said lower wall and said flap;
an internal compartment housed within the dashboard, said internal compartment being configured, dimensioned and positioned behind said housing and said internal compartment being capable of being accessed as said housing pivots from said closed position to said open position;
an airbag being configured and dimensioned to be stored and received within said interior volume when said airbag is in an un-inflated state and said airbag being configured, dimensioned and positioned to extend outwardly from said interior volume and restrain the occupant when said airbag is in an inflated state;
an inflator for inflating said airbag, said airbag causing said flap to pivot from said first position to said second position as said inflator inflates said airbag, said flap making contact with a portion of the occupant when said flap is in said second position;
a protective membrane being configured, dimensioned and positioned to extend from said rear wall, said lower wall and said flap and cover said airbag. - View Dependent Claims (13, 14, 21, 22, 23)
