Lateral airbag device
View Patent ↗A lateral airbag device comprises a gas bag which is mounted in a vehicle seat below the seat covering of the vehicle seat. The gas bag is inflated in the event of an accident. The seat covering comprises at least one break line, which can be torn open when the gas bag unfolds enabling the gas bag to exit the vehicle seat. The lateral airbag device is capable of protecting the occupants of a vehicle in the event of an accident in a reliable manner. The seat covering is configured to bring the unfolding gas bag to a predetermined position or to maintain the unfolded gas bag in the predetermined positioned.
1. A lateral airbag device, comprising:
an airbag mounted in a vehicle seat below a seat cover of the vehicle seat, the airbag being inflated in an event of a vehicle accident;
wherein the seat cover includes at least two tear seam sections which are separated by a non-tearing-open seat cover section, the at least two tear seam sections are torn open by the deploying airbag and permit the airbag to emerge from the vehicle seat, wherein the deploying airbag deploys into a predetermined position by a configuration of the seat cover, or the seat cover maintains a predetermined position of the airbag; and
at least one supporting element fastened to the seat cover in a region of the tear seam in such a manner that an airbag region tearing open the tear seam is supported by the supporting element,
wherein the supporting element is formed by a supporting bag, the supporting bag being fastened to the seat cover in the region of the tear seam in such a manner that an airbag region of the airbag which is assigned to the supporting bag deploys into the supporting bag and pushes the supporting bag outward out of an interior of the seat.
2. The lateral airbag device as claimed in claim 1 , wherein at least a partial section of the airbag is kept back in an interior of the vehicle seat by the non-tearing-open seat cover section.
3. The lateral airbag device as claimed in claim 1 , wherein the supporting element is sewn to the seat cover.
4. A vehicle seat, comprising:
a lateral airbag device that includes an airbag mounted in a vehicle seat below a seat cover of the vehicle seat, the airbag being inflated in an event of a vehicle accident,
wherein the seat cover includes at least two tear seam sections which are separated by a non-tearing-open seat cover section, the at least two tear seam sections are torn open by the deploying airbag and permit the airbag to emerge from the vehicle seat, and
wherein the deploying airbag deploys into a predetermined position by a configuration of the seat cover, or the seat cover maintains a predetermined position of the airbag,
at least one supporting element fastened to the seat cover in a region of one of the tear seam sections in such a manner that an airbag region tearing open the one tear seam section is supported by the supporting element, and
wherein the supporting element is formed by a supporting bag, the supporting bag being fastened to the seat cover in the region of the tear seam in such a manner that an airbag region of the airbag which is assigned to the supporting bag deploys into the supporting bag and pushes the supporting bag outward out of an interior of the seat.
5. A method for protecting a vehicle occupant, comprising:
positioning an airbag in a vehicle seat such that the airbag is inflated in an event of an accident; and
tearing open at least two tear seam sections in a seat cover of the vehicle seat which are separated by a non-tearing-open seat cover section such that the airbag deploys through openings from the opened tear seam sections,
wherein a position of the deploying or of the deployed airbag is determined by the seat cover,
wherein the positioning is carried out by a supporting element fastened to the seat cover in a region of the tear seam by an airbag region tearing open the tear seam being supported by said supporting element, and
wherein the supporting element includes a supporting bag fastened to the seat cover in the region of the tear seam in such a manner that an airbag region of the airbag which is situated in a region of the supporting bag deploys into the supporting bag and pushes the supporting bag outward out of an interior of the seat.
6. The method as claimed in claim 5 , wherein the airbag is supported by the seat cover.
7. The method as claimed in claim 5 , wherein at least one partial section of the airbag being kept back in an interior of the vehicle seat by the non-tearing-open seat cover section.
8. The method as claimed in claim 5 , wherein the supporting element is sewn to the seat cover.
