Abstract

An airbag for a vehicle has an attachment pocket with a through-opening, which extends through the layers of the attachment pocket, a first flat attachment means with a through-hole, wherein the first attachment means is arranged in the attachment pocket so that the through-hole is exposed on both sides of the attachment pocket through the opening, a second attachment means with a threaded area, a coupling area, and a head area, a spacing means, which is formed on the first attachment means and/or on the second attachment means, wherein the threaded area is designed to be connected to a corresponding vehicle-side threaded means.

Claims

1. An airbag for a vehicle, comprising:

an attachment pocket with a through-opening, which extends through the layers of the attachment pocket,

a first flat attachment means with a through-hole, wherein the first attachment means is arranged in the attachment pocket so that the through-hole is exposed on both sides of the attachment pocket through the opening,

a second attachment means with a threaded area, a coupling area, and a head area,

a spacing means, which is formed on the first attachment means wherein the spacing means comprises a thickened area which is formed around the through-hole of the first attachment means and protrudes from the opening of the attachment pocket,

wherein

the threaded area is designed to be connected to a corresponding vehicle-side threaded means,

the second attachment means can be introduced into the through-hole of the first attachment means, so that the coupling area is in contact with an inner surface of the through-hole,

the head area has a larger diameter than the through-hole and comprises a drive profile, and

the spacing means is configured in order to prevent a jamming of a portion of the attachment pocket by the first attachment means at the time of the attachment of the airbag to the vehicle.

2. The airbag according to claim 1, wherein the spacing means comprises a step section, wherein the step section has a larger diameter than the through-hole of the first attachment means and a smaller diameter than the through opening of the attachment pocket.

3. The airbag according to claim 1, wherein the second attachment means has a tubular portion, wherein the threaded area is formed as inner thread in the tubular portion which can be connected to the vehicle-side thread, in particular in the form of a threaded bolt, and wherein the coupling area is formed by at least one section of an outer lateral surface of the tubular portion.

4. The airbag according to claim 1, wherein the second attachment means has a bolt-shaped portion, wherein the threaded area is formed as outer thread on the bolt-shaped portion, which can be connected to the vehicle-side threaded means, in particular in the form of a threaded hole, and wherein the coupling area is formed by at least a portion of a shank of the bolt-shaped portion between the threaded area and the head area.

5. The airbag according to claim 1, wherein the first attachment means is rotatably arranged in the attachment pocket.

6. The airbag according to claim 5, wherein the through-hole of the first attachment means and the coupling area of the second attachment means are configured in such a manner that the second attachment means can be connected in a clamping manner by means of a predeterminable clamping force to the first attachment means, wherein the predeterminable clamping force prevents the first and second attachment means from coming apart.

7. The airbag according to claim 6, wherein the predeterminable clamping force allows a relative twisting between the first and second attachment means.

8. The airbag according to claim 1, wherein the spacing means is configured in order to prevent jamming of the first attachment means between the second attachment means and a vehicle frame at the time of the screwing of the second attachment means to the vehicle-side threaded means.

9. An airbag for a vehicle, comprising:

an attachment pocket with a through-opening, which extends through the layers of the attachment pocket,

a first flat attachment means with a through-hole, wherein the first attachment means is arranged in the attachment pocket so that the through-hole is exposed on both sides of the attachment pocket through the opening,

a second attachment means with a threaded area, a coupling area, and a head area,

a spacing means, which is formed on the second attachment means wherein the spacing means comprises a spacing section which adjoins the coupling area of the second attachment means and is configured so as to prevent the distance between the head area and a vehicle frame from falling below a predetermined distance at the time of the screwing of the second attachment means to the vehicle-side threaded means,

wherein

the threaded area is designed to be connected to a corresponding vehicle-side threaded means,

the second attachment means can be introduced into the through-hole of the first attachment means, so that the coupling area is in contact with an inner surface of the through-hole,

the head area has a larger diameter than the through-hole and comprises a drive profile, and

the spacing means is configured in order to prevent a jamming of a portion of the attachment pocket by the first attachment means at the time of the attachment of the airbag to the vehicle.

10. The airbag according to claim 9, wherein the spacing means comprises a spacing section which adjoins the coupling area of the second attachment means and is configured so as to prevent the distance between the head area and a vehicle frame from falling below a predetermined distance at the time of the screwing of the second attachment means to the vehicle-side threaded means.

11. The airbag according to claim 10, wherein the second attachment means has a tubular portion, wherein the threaded area is formed as inner thread in the tubular portion which can be connected to the vehicle-side thread, in particular in the form of a threaded bolt, and wherein the coupling area is formed by at least one section of an outer lateral surface of the tubular portion.

12. The airbag according to claim 9, wherein the second attachment means has a tubular portion, wherein the threaded area is formed as inner thread in the tubular portion which can be connected to the vehicle-side thread, in particular in the form of a threaded bolt, and wherein the coupling area is formed by at least one section of an outer lateral surface of the tubular portion.

13. The airbag according to claim 9, wherein the spacing means is configured in order to prevent jamming of the first attachment means between the second attachment means and a vehicle frame at the time of the screwing of the second attachment means to the vehicle-side threaded means.
