Abstract

Embodiments of the invention provide airbags that are guided by the seat belt, but that are not installed or incorporated into the seat belt itself. The airbags may be installed on a seat side, seat backrest, or in the seat armrest. The airbags are associated with a guiding strip that uses the seat belt to guide the airbag into the proper position in front of the passenger.

Claims

1. An airbag system for use with a passenger seat having a seat belt and an airbag, comprising:

(a) a guiding strip configured to be associated with but provided as a separate component from the seat belt, the guiding strip having (i) a first fixed point secured to an area along a side of the passenger, and (ii) a second fixed point secured to the seat belt;

(b) a sliding component configured to travel along the guiding strip, the sliding component being secured to at least a portion of the airbag.

2. The airbag system of claim 1, wherein the first fixed point is secured along a side of the seat, along an edge of the armrest, or to a side edge the seat belt.

3. The airbag system of claim 1, wherein the second fixed point is positioned at about a middle portion of the seat belt.

4. The airbag system of claim 1, wherein the airbag is positioned alongside the seat in the seat pan, in the seat back, along the armrest, or in the armrest.

5. The airbag system of claim 1, wherein the sliding component is a sliding ring.

6. The airbag system of claim 1, wherein the airbag comprises a buckle or clip to secure it to the sliding component.

7. The airbag system of claim 1, further comprising a cover configured to cover the guiding strip prior to use.

8. The airbag system of claim 7, wherein the cover comprises one or more tearing seams to expose the guiding strip in use.

9. The airbag system of claim 7, wherein the cover is secured at either end of the seat belt.

10. The airbag system of claim 1, wherein the guiding strip comprises the seat belt itself so that in use, the seat belt guides the deployment of the airbag.

11. The airbag system of claim 1, wherein the guiding strip is hinged or secured to the side of the seat or armrest or under the armrest or to the side of the seat belt by a further sliding component, said further sliding component is configured to permit the guiding strip to travel through the further sliding component and guide the deployment of the airbag.

12. An airbag system for use with a passenger seat having a seat belt and an airbag, comprising:

(a) a guiding strip arranged generally along a similar axis as the seat belt and secured at two fixed points, (i) a first fixed point secured to an area along a side of the passenger, and (ii) a second fixed point secured to the seat belt;

(b) a sliding component secured to at least a portion of the airbag and positioned near one of the fixed points of the guiding strip prior to airbag deployment, wherein the sliding component cooperates with the guiding strip to permit the sliding component to travel along the guiding strip and guide the deployment of the airbag.

13. The airbag system of claim 12, wherein the guiding strip comprises a cable, cord, or strip.
