Airbag tether release
An airbag system includes an airbag. The airbag system includes a base defining a track extending from a first end to a second end. The airbag system includes a carrier releasably fixed to the base and removable from the base at the second end. The airbag system includes a tether extending from the carrier and secured to the airbag. The airbag system includes a spring disposed at the first end. The spring is disposed between the carrier and the base. Upon application of a force to the carrier, e.g., via the tether when the airbag is inflated, the carrier is released from the base and compresses the spring. Upon removal of the force, the spring urges the carrier toward the second end where the carrier is ejected.
1. An airbag system, comprising:
an airbag;
a base defining a track extending from a first end to a second end;
a carrier releasably fixed to the base and removable from the base at the second end;
a tether extending from the carrier and secured to the airbag; and
a spring disposed at the first end and between the carrier and the base.
2. The airbag system of claim 1 , further comprising a seat supporting the airbag and the base.
3. The airbag system of claim 1 , further comprising a pin releasably fixing the carrier to the base, the pin being designed to break when the tether is pulled when the airbag is inflated.
4. The airbag system of claim 1 , wherein the spring urges the carrier in a direction opposite a deployment direction of the airbag.
5. An airbag tether anchoring device comprising:
a base defining a track extending from a first end to a second end;
a carrier releasably fixed to the base and removable from the base at the second end;
a tether extending from the carrier; and
a spring disposed at the first end and between the carrier and the base.
6. The airbag tether anchoring device of claim 5 , wherein the tether extends from the first end.
7. The airbag tether anchoring device of claim 5 , further comprising a ramp supported by the base and disposed at the second end.
8. The airbag tether anchoring device of claim 7 , wherein the base includes a hole, and the ramp is disposed between the hole and the carrier.
9. The airbag tether anchoring device of claim 7 , wherein the carrier is disposed between the ramp and the spring.
10. The airbag tether anchoring device of claim 5 , wherein the carrier includes an extension portion disposed within the spring.
11. The airbag tether anchoring device of claim 5 , wherein the carrier includes an extension portion, and the base includes an extension receiving portion that defines a passage designed to permit the extension portion to be slidably received therein.
12. The airbag tether anchoring device of claim 11 , wherein the base includes a distal end and a channel extending from the distal end to the first end along the passage, the channel being open to the passage.
13. The airbag tether anchoring device of claim 12 , wherein a width of the passage is greater than a width of the channel.
14. The airbag tether anchoring device of claim 11 , wherein the extension portion is disposed within the extension receiving portion.
15. The airbag tether anchoring device of claim 5 , further comprising a pin releasably fixing the carrier to the base.
16. The airbag tether anchoring device of claim 15 , wherein the pin is designed to break when the tether is pulled by an inflating airbag.
17. The airbag tether anchoring device of claim 5 , wherein the base includes a distal end and a channel extending from the distal end to the first end, and wherein the tether is disposed within the channel and extends through the distal end.
18. The airbag tether anchoring device of claim 5 , wherein the carrier is configured to be slidable along the track to a compressed position when the carrier is released from being fixed to the base, the spring being compressed between the base and the carrier in the compressed position.
19. The airbag tether anchoring device of claim 18 , wherein the carrier includes a distal end that abuts the base in the compressed position.
20. The airbag tether anchoring device of claim 18 , wherein the carrier includes an extension portion, the base includes an extension receiving portion that defines a passage, and the extension portion is disposed in the passage in the compressed position.
