Abstract: A knee airbag module includes an inflatable knee airbag, an inflator for inflating the knee airbag, a housing for supporting the knee airbag and inflator, a cover for enclosing the knee airbag in the housing, and a deployment flap positioned beneath the cover. The housing includes an opening through which the knee airbag deploys. The deployment flap is connected to the housing and spans across at least a portion of the opening. The knee airbag has a width that extends laterally beyond the lateral extent of the housing when the airbag is deployed. The knee airbag also includes a central portion that spans the width of the housing when the knee airbag is deployed. The deployment flap is configured to initially inhibit deployment of the central portion of the knee airbag while remaining portions of the knee airbag initially deploy. The deployment flap is configured to thereafter rupture and permit deployment of the central portion.

Abstract: The invention describes a vehicle occupant restraint system (2) comprising a control unit and at least two restraint elements (8, 10) for the protection of lower extremities (6, 6′, 7, 7′) in the area of a footwell (4) of a vehicle of a vehicle occupant seated in a particular vehicle seat of the vehicle, wherein a first restraint element (8) is configured as a knee airbag module (12), wherein a second restraint element (10) is provided for mounting into the footwell (4) of the vehicle, especially in an area of the footwell (4) of the vehicle arranged in the vehicle longitudinal direction (x) ahead of the knee airbag module (12), wherein, in a situation of restraint, the control unit can differentiate between different given situations, wherein the given situation can be determined via a vehicle seat position and parameters relating to vehicle occupants, wherein, in the situation of restraint, when a situation is given in which the vehicle seat (5) is in a position shifted backwards, especially in a position shifted backwards compared to the standard position, and the vehicle occupant is a short and/or light person, the control unit only activates the foot airbag module (16) of the second restraint element (10).

Abstract: A knee airbag cover for a vehicle includes a covering body configured to shield an airbag module from a passenger cabin. The covering body has an outer perimeter with an instrument panel facing side and a footwell facing side. The covering body also has an inner surface configured to face away from the passenger cabin and an outer surface configured to face toward the passenger cabin. The knee airbag cover further includes a footwell fastener. The footwell fastener is configured to attach a footwell so as to conceal the footwell fastener and an attachment of the covering body from the passenger cabin.

Abstract: A knee airbag apparatus includes an airbag that is configured to be accommodated in a holder arranged in an instrument panel of a vehicle. The airbag includes an upper inflation portion and a lower inflation portion. The upper inflation portion is configured to be deployed and inflated from the holder along a rear surface of the instrument panel in a rear upward direction to protect a knee of a lea of the occupant. The lower inflation portion is configured to be deployed and inflated from the holder in a downward direction or a diagonally rear downward direction such that a lower end of the lower inflation portion reaches a position where the lower end contacts an instep of a foot of the leg of the occupant or a position lower than the instep to protect the foot of the occupant.
