Inflatable airbag cushions can be rolled and/or folded into a housing assembly. The housing assembly aids in coupling an inflator to the airbag and a vehicle structure. The housing also couples the airbag to a vehicle structure. The housing can be mounted behind an knee bolster or steering wheel of a vehicle and has a cover that can be flush with the cabin side of the mounted position. The housing cover can be a cosmetically finished piece or a cosmetically unfinished piece. The housing cover can be an integral part of the housing, and may be used in combination with a one-piece inflator mounting bracket and heat shield.

1. An inflatable airbag assembly, comprising: a housing comprising a first longitudinal sidewall, a second longitudinal sidewall, a first lateral sidewall, and a second lateral sidewall, wherein the first longitudinal sidewall and the second longitudinal sidewall are opposite to each other, and wherein the first lateral sidewall and the second lateral sidewall are opposite to each other;a cover connected to the first longitudinal sidewall of the housing by a hinge;an inflator, wherein the inflator is coupled to a mounting stem that is received by an aperture in the housing;an inflatable airbag coupled to the inflator;a deployment strap comprising an inflator coupling portion and a strap portion, wherein the mounting stem extends through the inflator coupling portion to couple the deployment strap to the inflator, wherein the deployment strap is positioned around the inflator and a portion of the inflatable airbag such that the strap portion extends adjacent to the cover prior to deployment of the inflatable airbag; wherein the housing, the cover and the hinge comprise a single piece of material,wherein the second longitudinal sidewall of the housing and the cover comprises a plurality of cover closing structures, and wherein the cover closing structures of the housing are complementary to the cover closing structures of the cover;wherein, during inflatable airbag deployment, the deployment strap resists movement of the inflatable airbag in a direction toward the hinge and directs the inflatable airbag upward toward the first longitudinal sidewall, which causes the cover closing structures of the housing and of the cover to cease interacting with each other such that the cover rotates at the hinge and transitions from a closed configuration to an open configuration and causes the inflatable airbag to deploy in a car rearward and upward direction; andwherein the cover continues to be coupled to the housing via the hinge after the cover transitions to the open configuration. 2. The inflatable airbag assembly of claim 1, wherein the inflator mounting stem is coupled to a portion of the housing other than the cover. 3. The inflatable airbag assembly of claim 1, wherein the lateral sidewalls of the housing and the cover comprises another plurality of cover closing structures. 4. The inflatable airbag assembly of claim 1, wherein each of the cover closing structures on the airbag housing comprises an aperture. 5. The inflatable airbag assembly of claim 4, wherein each aperture of the cover closing structures on the airbag housing extends beyond the second longitudinal sidewall. 6. The inflatable airbag assembly of claim 1, wherein each of the cover closure structures of the housing comprises an “L” shape. 7. The inflatable airbag assembly of claim 1 wherein each of the cover closing structures of the cover comprises integral extensions of the cover. 8. The inflatable airbag assembly of claim 1, wherein the cover closing structures on the housing comprise push pins, and the cover closing structures on the cover comprise apertures that are configured to receive the push pins. 9. The inflatable airbag assembly of claim 1, wherein the cover closing structures on the housing comprise apertures, and the cover closing structures on the cover comprise push pins that are configured to be received by the apertures on the housing. 10. The inflatable airbag assembly of claim 1, wherein the inflator and the mounting stem are directly attached to each other. 11. The inflatable airbag assembly of claim 1, wherein the inflator is coupled to two mounting stems. 12. The inflatable airbag assembly of claim 11, wherein each of the mounting stems are directly attached to the inflator. 13. The inflatable airbag assembly of claim 1, wherein the assembly is configured to be mounted at a low mount position below a knee bolster of a vehicle. 14. The inflatable airbag assembly of claim 1, wherein the deployment strap comprises a woven nylon material. 15. The inflatable airbag assembly of claim 1, wherein the strap portion of the deployment strap has opposing ends. 16. The inflatable airbag assembly of claim 15, wherein each end terminates with a fastener. 17. The inflatable airbag assembly of claim 16, wherein each fastener is configured to be coupled to a complementary structure. 18. The inflatable airbag assembly of claim 16, wherein the assembly further comprises a mounting bracket coupled to the housing, wherein the ends of the strap portion extend out of the housing, and wherein each fastener is configured to couple to a complementary structure on the mounting bracket. 19. The inflatable airbag assembly of claim 18, wherein the mounting bracket is coupled to a rear portion of the housing via the mounting stem.
