Claims20
An airbag module for a vehicle, comprising:
- a first cushion unit, wherein the first cushion unit is a substantially U-shaped body member comprising:
- a pair of arms,
- an aperture between the pair of arms, and
- a chamber with a chamber volume;
- and
- a second cushion unit comprising a plurality of cushion cells,
- wherein the plurality of cushion cells are arranged adjacent to each other on a surface of the first cushion unit,
- wherein the plurality of cushion cells are configured to cover a region of the airbag module,
- wherein the region is arranged to face an interior space of the vehicle configured to carry one or more occupants,
- wherein each of the plurality of cushion cells are connected at each end of the cushion cell to a respective arm of the pair of arms, and
- wherein the plurality of cushion cells are further configured to form an intermediate layer between the first cushion unit and any occupant body part located at the region during a collision.
A vehicle, comprising:
- an airbag module, comprising:
- a first cushion unit, wherein the first cushion unit is a substantially U-shaped body member comprising:
- a pair of arms,
- an aperture between the pair of arms, and
- a chamber with a chamber volume;
- and
- a second cushion unit comprising a plurality of cushion cells,
- wherein the plurality of cushion cells are arranged adjacent to each other on a surface of the first cushion unit,
- wherein the plurality of cushion cells are configured to cover a region of the airbag module,
- wherein the region is arranged to face an interior space of the vehicle configured to carry one or more occupants,
- wherein each of the plurality of cushion cells are connected at each end of the cushion cell to a respective arm of the pair of arms, and
- wherein the plurality of cushion cells are further configured to form an intermediate layer between the first cushion unit and any occupant body part located at the region during a collision.
A method for protecting one or more occupants of a vehicle during a collision via an airbag module of the vehicle, the method comprising:
- providing the airbag module comprising a first cushion unit and a second cushion unit, the second cushion unit comprising a plurality of cushion cells, and the first cushion unit being a substantially U-shaped body member comprising:
- a pair of arms,
- an aperture between the pair of arms, and
- a chamber with a chamber volume;
- and
- arranging the plurality of cushion cells adjacent to each other on a surface of the first cushion unit, wherein each of the plurality of cushion cells are connected at each end of the cushion cell to a respective arm of the pair of arms, wherein the arranging comprises arranging the plurality of cushion cells of the second cushion unit to:
- cover a region of the airbag module that faces an interior space of the vehicle configured to carry one or more occupants, and
- form an intermediate layer between the first cushion unit and any occupant body part located at the region during the collision.
