3. The apparatus according to claim 1 , wherein the first traction element the second end of the first traction element is attached to a second lateral side of the seat frame and the first traction element laterally extends across the seat frame from the first lateral side to the second lateral side.
4. The apparatus according to claim 1 , wherein the airbag cushion includes a frontal region, the frontal region having a thickness greater than the central region of the airbag cushion when the airbag apparatus is deployed and the airbag cushion is inflated.
5. The apparatus according to claim 1 , further comprising a second traction element and a third traction element, both of the second and third traction elements attached by to a frontal region of the airbag cushion.
6. The apparatus according to claim 5 , wherein the second traction element and the third traction element are arranged on and attached to the first side of the seat frame.
7. The apparatus according to claim 5 , wherein the second traction element is arranged above the first traction element, and the third traction element is arranged below the first traction element.
8. An airbag apparatus for attachment to a seat frame of a vehicle seat in combination with the vehicle seat, the airbag apparatus comprising:
an airbag cushion deployable on a first lateral side of the seat frame in a plane extending parallel to a vehicle longitudinal direction and perpendicular to a lateral direction, the airbag cushion including a recessed central region for accommodating a shoulder of a vehicle passenger; and
a first traction element having a first end attached to the central region of the airbag cushion and a second end attached to a second lateral side of the seat frame, the first traction element extending In the lateral direction across the seat frame from the recessed central region of the airbag cushion to the second lateral side.
9. The airbag cushion according to claim 8 , wherein the first traction element is attached by the first end in a rear part of the recessed central region of the airbag cushion.
10. The airbag cushion according to claim 9 , wherein the first traction element is attached by the first end thereof near to a first internal strap in a rear part of the recessed central region of the airbag cushion, the first internal strap cooperating with a second internal strap to define the recessed central region.
11. The airbag cushion according to claim 8 , wherein the airbag cushion includes a frontal region having a thickness greater than the recessed central region of the airbag cushion when the airbag cushion is inflated.
12. The airbag cushion according to claim 8 , wherein the airbag cushion has a second traction element and a third traction element, each of the first and second traction elements attached to a frontal region of the airbag cushion.
13. The airbag cushion according to claim 12 , wherein the second traction element and the third traction element are each attached to the lateral first side of the seat frame.
14. The airbag cushion according to claim 12 , wherein the second traction element is arranged above the first traction element, and the third traction element is arranged below the first traction element.
