Abstract

An airbag sleeve configured to securely retain an airbag includes a main body, a first latching member, and a second latching member. The main body includes first and second edges and defined an airbag retention area. The first latching member is connected to the first edge, while the second latching member is connected to the second edge. The first and second latching members are configured to interlock together in a closed position in order to securely retain the airbag within the airbag retention area. The first and second latching members are also configured to separate from one another when the airbag deploys.

Claims

1. An airbag sleeve configured to securely retain an airbag comprising:

a main body having first and second edges, said main body defining an airbag retention area;

a first latching member connected to said first edge; and

a second latching member connected to said second edge, wherein said first and second latching members are configured to interlock together in a closed position in order to securely retain the airbag within said airbag retention area, and wherein said first and second latching members are configured to separate from one another when the airbag expands.

2. The airbag sleeve of claim 1, wherein said first latching member comprises first and second channels separated by a first rail, and wherein said second latching member comprises second and third rails separated by a third channel, wherein said first and second channels mate with said second and third rails, and wherein said first rail mates with said third channel.

3. The airbag sleeve of claim 1, wherein one or both of said first and second latching members comprise a perforation over a length thereof, wherein said perforation ensures a controlled tear when the airbag is deployed.

4. The airbag sleeve of claim 1, wherein said main body includes an angled end, wherein said angled end ensures a controlled tear when the airbag is deployed.

5. The airbag sleeve of claim 1, wherein said first and second latching members are different lengths, wherein said different lengths ensure a controlled tear when the airbag is deployed.

6. The airbag sleeve of claim 1, wherein said airbag sleeve further comprises at least one slot configured to allow a mounting tab of the airbag to pass therethrough.

7. The airbag sleeve of claim 1, wherein said main body is an extruded plastic sheet.

8. The airbag sleeve of claim 1, wherein a first end of said first latching member is heat staked to a second end of said second latching member.

9. An automobile airbag system comprising:

an airbag; and

an airbag sleeve that securely retains said airbag in a pre-deployed state and opens to allow said airbag to expand in a deployed state, said airbag sleeve comprising;

a main body having first and second edges, said main body defining an airbag retention area;

a first latching member connected to said first edge;

a second latching member connected to said second edge, wherein said first and second latching members are configured to interlock together in a closed position in order to securely retain said airbag within said airbag retention area before said airbag deploys, and wherein said first and second latching members are configured to separate from one another when said airbag deploys.

10. The system of claim 9, wherein said airbag comprises a flap that is anchored to said airbag sleeve.

11. The system of claim 10, wherein said main body comprises first and second wall portions, wherein said flap is compressively sandwiched between said first and second wall portions.

12. The system of claim 10, wherein said main body comprises a flap-anchoring slot, wherein said flap is anchored within said flap-anchoring slot.

13. The system of claim 9, wherein said main body comprises a thick portion and a thin portion, wherein said thick portion of said main body provides rigidity and strength and said thin portion provides flexibility.

14. The system of claim 9, wherein said first latching member comprises first and second channels separated by a first rail, and wherein said second latching member comprises second and third rails separated by a third channel, wherein said first and second channels mate with said second and third rails, and wherein said first rail mates with said third channel.

15. The system of claim 9, wherein one or both of said first and second latching members comprise a perforation over a length thereof, wherein said perforation ensures a controlled tear when the airbag is deployed.

16. The system of claim 9, wherein said main body includes an angled end, wherein said angled end ensures a controlled tear when the airbag is deployed.

17. An airbag sleeve configured to securely retain an airbag, the airbag and airbag sleeve configured to be securely fastened to a structure within an automobile, the airbag sleeve comprising:

a main body formed of plastic and having first and second edges, said main body defining an airbag retention area;

at least one slot formed through said main body and configured to allow a mounting tab of the airbag to pass therethrough;

a first latching member connected to said first edge, said first latching member comprising first and second channels separated by a first rail; and

a second latching member connected to said second edge, said second latching member comprising second and third rails separated by a third channel, wherein said first and second latching members are configured to interlock together in a closed position in order to securely retain the airbag within said airbag retention area before the airbag deploys, and wherein said first and second latching members are configured to separate from one another when the airbag deploys.

18. The airbag sleeve of claim 17, wherein one or both of said first and second latching members comprise a perforation over a length thereof, wherein said perforation ensures a controlled tear when the airbag is deployed.

19. The airbag sleeve of claim 17, wherein said main body includes an angled end, wherein said angled end ensures a controlled tear when the airbag is deployed.

20. The airbag sleeve of claim 17, wherein a portion of said first latching member is heat staked to a portion of said second latching member.
