10. The apparatus as in claim 9, wherein the second engagement portion further comprises another locking member depending laterally away from the second engagement portion in a direction opposite to the locking member, the another locking member further comprising a tab portion for engaging another opening after the first engagement portion has passed through the elongated opening.

11. The apparatus as in claim 8, wherein the locking member is configured to have a locking tab depending away from the locking member, wherein the locking tab is configured and positioned to engage another opening after the first engagement portion has passed through the elongated opening.

12. The apparatus as in claim 8, wherein the locking member further comprises a first locking member depending laterally away from the second engagement portion in a first direction and a second locking member depending laterally away from second engagement portion in a second direction, the second direction being opposite the first direction, wherein the first locking member is configured to have a first locking feature depending away from the first locking member, wherein the first locking feature is configured and positioned to engage a portion of an elongated opening after the first engagement portion has passed therethrough and the second locking member is configured to have a second locking feature depending away from the second locking member, wherein the second locking feature is configured and positioned to engage an other opening after the first engagement portion has passed through the opening.

13. The apparatus as in claim 12, wherein the first locking feature is a chamfered surface and the second locking feature is a tab portion.

14. The apparatus as in claim 8, wherein the first engagement portion comprises a pair of first engagement portions, the pair of first engagement portions being in a facing spaced relationship with respect to the second engagement portion and the locking member further comprises a pair of locking members depending laterally away from the second engagement portion, wherein each of the pair of locking members is configured to have a locking tab.

15. The apparatus as in claim 8, wherein the second engagement portion is insert molded about a mounting portion of an inflatable cushion.

16. An attachment clip for attaching an inflatable cushion to a vehicle, the attachment clip comprising:

a first outer portion;

a second outer portion;

an intermediate portion coupled to and disposed between the first outer portion and the second outer portion, wherein the first outer portion is in a facing spaced relationship with respect to the intermediate portion in a first position of the first outer portion and the second outer portion is also in a facing spaced relationship with respect to the intermediate portion in an initial position of the second outer portion; and

an engagement tab depending away from the first outer portion, a portion of the engagement tab being received within an opening in the intermediate portion, when the first outer portion is in the first position.

17. The attachment clip as in claim 16, wherein the second outer portion has a pair of tabs depending away from an outer periphery of the second outer portion.
