An inflatable knee airbag is typically stored in a packaged state within an airbag housing. The housing often has a cover, which can be either a cosmetic cover or an unfinished cover, if the cover will not be readily visible to an occupant. During inflatable airbag deployment, the housing may contribute to determining the airbag's trajectory. A car-forward portion of an airbag housing that is horizontally oriented may rotate in a car-downward direction to allow a deployment trajectory of the deploying airbag to be more vertically oriented.

1. An inflatable knee airbag assembly comprising: an inflatable knee airbag;an inflator coupled to the inflatable knee airbag; anda housing coupled to the inflator, wherein in a packaged configuration, the inflatable knee airbag is contained within the housing and the housing is in a contracted configuration,wherein the housing comprises a car-upward portion opposite from a car-downward portion,wherein the housing comprises a car-forward wall opposite from a car-rearward opening,wherein in a deployed configuration, the car-downward portion has rotated about a hinge such that the housing is in an extended configuration, wherein the car-forward wall has a greater height in the extended configuration than in the contracted configuration,wherein the inflatable knee airbag exits the housing in a car-rearward direction via the car-rearward opening of the housing, andwherein the car-rearward opening of the housing has a height that remains the same in the deployed configuration and in the contracted configuration. 2. The inflatable airbag assembly of claim 1, wherein the hinge is located on the car-downward portion of the housing. 3. The inflatable airbag assembly of claim 1, wherein the hinge is located adjacent to the car-rearward opening of the housing. 4. The inflatable airbag assembly of claim 1, wherein the housing comprises two side portions, and wherein each of the side portions expands when transitioning from the constricted configuration to the expanded configuration. 5. The inflatable airbag assembly of claim 1, wherein the car-forward wall moves in a car-downward direction when the housing transitions from the constricted configuration to the expanded configuration. 6. The inflatable airbag assembly of claim 4, wherein the housing is configured such that pressure from inflation gas causes the inflatable knee airbag to push the car-forward portion of the car-downward portion of the housing in the car-downward direction, which enables the inflatable knee airbag to have an initial deployment trajectory in a car-upward and car-rearward direction. 7. An inflatable airbag assembly comprising: an inflatable airbag;an inflator coupled to the inflatable airbag; anda housing coupled to the inflator, wherein the housing comprises a car-upward portion and a car-downward portion, wherein the car-upward portion comprises a rigid reaction plate, and wherein a car-forward wall of the housing comprises a plurality of folds that permit the car-downward portion to rotate relative to the rigid reaction plate,wherein, when the assembly is in a packaged configuration, the airbag is contained within the housing and the housing is in a contracted configuration, andwherein, when the assembly transitions to a deployed configuration, the folds expand so that the housing is moved to an extended configuration, wherein a car-forward portion has a greater height in the extended configuration than in the contracted configuration. 8. The inflatable airbag assembly of claim 7, wherein the car-downward portion comprises a hinge region. 9. The inflatable airbag assembly of claim 8, wherein the housing is configured such that pressure from inflation gas acting on the airbag causes a portion of the car-downward portion to rotate about the hinge region. 10. The inflatable airbag assembly of claim 7, wherein the inflator is coupled to the car-upward portion of the housing. 11. The inflatable airbag assembly of claim 7, wherein the inflator is coupled to the car-downward portion of the housing. 12. An inflatable airbag assembly comprising: an inflatable airbag;an inflator coupled to the inflatable airbag; anda housing coupled to the inflator, wherein the housing comprises a car-upward portion and a car-downward portion, and wherein the car-upward portion comprises a rigid member and wherein the car-downward portion comprises a plastic member,wherein a car-forward wall of the housing comprises a plurality of folds,wherein the car-downward portion comprises a living hinge,wherein in a packaged configuration, the airbag is contained within the housing and the housing has a contracted configuration,wherein in a deployed configuration, the housing comprises an extended configuration, wherein the car-forward wall has a greater height than in the contracted configuration, andwherein in the deployed configuration and in the constricted configuration, a car-rearward portion has a same height. 13. The inflatable airbag assembly of claim 12, wherein the housing is configured such that inflation gas causes the inflatable airbag to apply pressure to a car-downward wall of the car-downward portion. 14. The inflatable airbag assembly of claim 13, wherein a car-forward portion of the car-downward wall rotates in a car-downward direction, such that a car-rearward portion of the car-downward portion acts as a hinge. 15. The inflatable airbag assembly of claim 12, wherein the housing comprises a plurality of sidewalls, and wherein each sidewall comprises accordion folds. 16. The inflatable airbag assembly of claim 12, wherein the inflator is coupled to the car-upward portion of the housing. 17. The inflatable airbag assembly of claim 12, wherein the inflator is coupled to the car-upward portion of the housing.
