The invention relates to an airbag module (10) of a vehicle occupant restraint system, specifically a knee airbag module, comprising a folded inflatable airbag (12) for restraining a vehicle occupant, a module housing (14) which includes a flexible airbag sheath (16) at least partially enclosing the folded airbag (12), and comprising a module cover (18) which includes fasteners (20) for fastening the module cover (18) to the module housing (14), wherein the flexible airbag sheath (16) of the module housing (14) is fixed directly to said fasteners (20), and wherein at least one flexible anchoring element (22, 22′) is provided which extends between the folded airbag (12) and the module cover (18) and limits or prevents expansion of the folded airbag (12) toward the module cover (18).

An occupant protecting device for a vehicle has a knee airbag that is disposed at a seat front side of a vehicle seat, and that, at a time of a front collision of a vehicle, deploys, and restrains leg portions of a vehicle occupant seated in the vehicle seat. A foot airbag is disposed at the seat front side of the vehicle seat. At a time of a front collision of the vehicle, when a seat front-rear direction position of the vehicle seat is disposed further toward a rear side than a predetermined position, the foot airbag deploys between the knee airbag and the leg portions of the vehicle occupant seated in the vehicle seat, and restrains the leg portions of the vehicle occupant seated in the vehicle seat.

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 situations, wherein the control unit, in the situation of restraint, activates at least the first restraint element (8) and, depending on the given situation, additionally activates the second restraint element (10) and/or a partial element of the first restraint element (8) and/or a partial element of the second restraint element (10).

A knee airbag for vehicles is provided. The knee airbag includes a lower crash pad that has a panel shape to block a steering column to prevent exposure of the steering column to an indoor space of a vehicle, and includes a housing unit having recesses dented toward the steering column such that the housing unit is spaced apart from the steering column by a designated distance. An airbag module of the knee airbag includes an inflator and a cushion and contained in the housing unit of the lower crash pad to deploy the cushion toward a driver's knee outside the lower crash pad when the cushion is deployed by explosion of the inflator.

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.

Driver-side knee airbags, for vehicles, are described herein. One airbag has at least one cushion pack. Each cushion pack has an airbag cushion to be deployed. The airbag has an inflator. The inflator is outside of and coupled to the cushion pack, and is for inflating the airbag cushion. The cushion pack is dimensioned to be positioned below the steering column of the vehicle. Another airbag has a single cushion pack. The single cushion pack has a single airbag cushion to deploy. An inflator is inside the single airbag cushion. The single cushion pack is dimensioned to mount in a vertical orientation offset to one side of the steering column of the vehicle. In multiple versions of the airbag, an inflator is dimensioned to mount offset to one side of the steering column of the vehicle.

An occupant protection device, which protects an occupant seated in a seat, includes: a seat belt; a front airbag device provided with a front airbag which is placed in an area of a lap belt and inflates to cover a front of the occupant when operated; and a seat airbag device provided with a seat airbag which is arranged inside a seat portion in the seat and inflates so as to raise at least a front portion side of the seat portion upward. The front airbag causes inflation gas to flow into the inside and inflates so as to protrude forward and upward when operated and a thigh abutment surface abutting on a thigh of the occupant and an upper body restraining surface restraining an upper body of the occupant are arranged on an outer peripheral surface of the front airbag when the inflation is completed.
