Air bag door and chute

1. An inflatable restraint assembly comprising:

an air bag door including at least one fastener integrally-formed with the air bag door; and

a chute including a recessed upper perimeter that receives the air bag door, and a chute lip perimeter and chute lip portions that mesh with and are positioned in the same plane with peripheral lip portions extending from the air bag door, wherein the at least one fastener is extended through at least one passage formed in the recessed upper perimeter of the chute, and wherein the chute is adapted to interlock with the at least one fastener for retaining said air bag door to said chute.

2. The inflatable restraint assembly according to claim 1 , wherein the at least one fastener comprises a snap tab that frictionally engages at least one rib integrally-formed with the chute.

3. The inflatable restraint assembly according to claim 2 , wherein the at least one snap tab extends substantially perpendicularly away from an inboard surface of the door, wherein the rib extends from an outboard chute perimeter surface.

4. The inflatable restraint assembly according to claim 3 , wherein the at least one snap tab includes a ramped end and a notched section, wherein the rib is located in the notched section to create the interlock effect.

5. The inflatable restraint assembly according to claim 1 , wherein the chute and the air bag door is made of one of thermoplastic olefin (TPO), nylon, and glass fiber reinforced polypropylene (PP).

6. A method for manufacturing an inflatable restraint assembly, comprising the steps of:

integrally forming an air bag door with at least one fastener from a formable material;

forming a chute from the formable material, wherein the chute includes a recessed upper lip perimeter for receiving the air bag door, a chute lip perimeter, and at least one chute lip tab that is adapted to be aligned with at least one peripheral lip portion of the air bag door.

7. The method according to claim 6 , wherein the chute includes at least one rib for interlocking with the at least one fastener.

8. The method according to claim 7 , wherein the at least one fastener includes a ramped end and a notched section, wherein the notched section is adapted to receive the at least one rib.

9. A method for assembling an inflatable restraint assembly, comprising the steps of:

aligning a chute lip perimeter and at least one chute lip tab of a chute with at least one peripheral lip portion of an air bag door;

receiving the air bag door at a recessed upper lip perimeter of the chute;

inserting at least one fastener extending from the air bag door into at least one passage formed in the chute;

interlocking the at least one fastener with the chute; and

receiving a rib extending from the chute in a notched section of the at least one fastener to interlock the fastener and chute.

10. An inflatable restraint assembly comprising:

a chute including a chute lip perimeter defining chute lip portions, and a surface defining at least one passage; and

an air bag door including peripheral lip portions that mesh with the chute lip portions, and at least one fastener that extends through the at least one passage and interlocks the air bag door with the chute, wherein the at least one fastener comprises a snap tab that frictionally engages at least one rib integrally-formed with the chute.

11. The inflatable restraint assembly according to claim 10 , wherein the surface of the chute defines a recessed upper perimeter, wherein the chute lip portions are positioned in the same plane with peripheral lip portions.

12. The inflatable restraint assembly according to claim 10 , wherein the at least one snap tab extends substantially perpendicularly away from an inboard surface of the door, wherein the rib extends from an outboard chute perimeter surface.

13. The inflatable restraint assembly according to claim 12 , wherein the at least one snap tab includes a ramped end and a notched section, wherein the rib is located in the notched section to create the interlock effect.
