Abstract

An airbag tether retainer is disclosed that is of minimal size to accommodate vehicle safety and styling requirements and yields to conform to contours of a vehicle pillar. The tether retainer is interchangeable with left or right vehicle pillars thus reducing fabrication costs. The tether retainer imposes minimal stress on a worker attaching the retainer. In certain embodiments, the tether retainer includes a body and one or more tabs and corresponding tab locks which extend from the body. An airbag tether is positioned on the body and each tab is looped around the tether and secured to the body by a corresponding tab lock. The body may then be secured to a vehicle pillar.

Claims

1. An airbag tether retainer comprising:

a generally planar body;

a tab that extends from a side of the body; and

a tab lock that engages the tab to secure an airbag tether between the tab and the body.

2. The airbag tether retainer of claim 1, wherein the tab comprises a catch and the tab lock comprises a slot sized to receive the tab and engage the catch when the catch is passed through the slot.

3. An airbag tether retainer of claim 2, wherein the catch comprises a pair of barbs extending from the tab in opposite directions, the barbs being shaped to allow the tab to readily pass through the slot in one direction and oppose passage of the tab through the slot in an opposite direction.

4. The airbag tether retainer of claim 2, wherein the catch comprises at least one detent sized and shaped to engage the slot of a tab lock.

5. The airbag tether retainer of claim 2, wherein the tab lock comprises a loop that extends from the body in a direction transverse to a plane defined by the body, the loop being sized to engage a catch.

6. The airbag tether retainer of claim 2, further comprising a release member that severs a tab when the airbag tether transmits tension to a tab engaged in the tab lock, the release member being positioned between the tab lock and the catch.

7. The airbag tether retainer of claim 1, wherein the tab lock is capable of releasing the tab when the airbag tether transmits tension to the tab engaged in the tab lock.

8. An airbag tether retainer of claim 1, wherein the tab lock comprises tape.

9. The airbag tether retainer of claim 1, wherein the body includes at least one mounting hole that allows the body to be mounted to a vehicle roof pillar.

10. The airbag tether retainer of claim 1, wherein the body conforms to the contour of a vehicle roof pillar.

11. An airbag tether retainer system comprising:

an airbag tether connected to a curtain airbag;

a generally planar body extending substantially parallel to the tether;

a plurality of tab locks that extend from the body; and

a plurality of tabs engaged by the tab locks to secure the tether to the body, the tabs being positioned opposite the tab locks.

12. The airbag tether retainer system of claim 11, wherein each tab lock is capable of releasing a tab when the airbag tether transmits tension to the tab engaged in the tab lock.

13. The airbag tether retainer system of claim 11, wherein each tab comprises a release member that severs the tab when the airbag tether transmits tension to the tab engaged in the tab lock.

14. The airbag tether retainer system of claim 11, wherein the airbag tether and body include corresponding mounting holes that allow the body and airbag tether to be mounted to a vehicle pillar.

15. The airbag tether retainer system of claim 11, wherein the airbag tether is a sail tether.

16. The airbag tether retainer system of claim 11, wherein the body conforms to the contour of a vehicle roof pillar.

17. The airbag tether retainer system of claim 11, wherein the body, tabs, and tab locks are formed from a single piece of flexible material.

18. An airbag tether retainer comprising:

an elongated generally planar body;

a plurality of tabs extending perpendicularly from one side of the body, each tab having a catch; and

a plurality of tab locks extending perpendicularly from an opposite side of the body, each tab lock being capable of engaging the catch of a tab.

19. The airbag tether retainer of claim 18, wherein each tab lock comprises a slot sized to receive a tab and each catch is sized and shaped to pass through the slot in one direction and oppose removal of the tab in an opposite direction.

20. The airbag tether retainer of claim 19, wherein each catch comprises a pair of barbs extending from a tab in opposite directions.

21. The airbag tether retainer of claim 20, wherein the body includes at least one mounting hole that allows the body to be mounted to a vehicle roof pillar.

22. The airbag tether retainer of claim 21, wherein the body conforms to the contour of a vehicle roof pillar.

23. The airbag tether retainer of claim 22, further comprising a plurality of release members that sever the plurality of tabs when the airbag tether transmits tension to tabs engaged in the tab locks, each release member being positioned between a tab lock and a corresponding catch.

24. The airbag tether retainer of claim 23, wherein the release member is a perforation.

25. The airbag tether retainer of claim 24, wherein the body, tabs, and tab locks are formed from a single piece of flexible material.

26. An airbag tether retainer comprising:

a strap having a head and a tail;

wherein the head and tail are capable of securely engaging each other to encircle and retain an airbag tether.

27. An airbag tether retainer of claim 26, wherein the strap includes a mounting member for affixing the strap to a vehicle roof pillar.

28. The airbag tether retainer of claim 26, wherein the strap comprises a fastener disposed in the head and a catch disposed in the tail.

29. An airbag tether retainer of claim 28, wherein the fastener comprises a slot and the catch comprises a pair of barbs extending from the tail in opposite directions, the barbs being shaped to allow the tail to readily pass through the slot in one direction and oppose passage of the tail through the slot in an opposite direction.

30. The airbag tether retainer of claim 26, further comprising a plurality of straps.

31. The airbag tether retainer of claim 26, wherein the strap comprises a release member that readily severs the strap when the airbag tether transmits tension to the strap encircling and retaining the airbag tether, the release member being strategically positioned between the head and the tail.

32. The airbag tether retainer of claim 26, wherein the head and tail are capable of engaging each other by way of a knot.

33. The airbag tether retainer of claim 26, wherein the head and the tail are substantially the same size and shape.
