Abstract

A number of variations may include a product comprising an airbag which propels a moving member that releases a hood hinge mechanism upon deployment and which deploys a cushion to provide pedestrian protection from at least one of a rearward region of the hood, a lower windshield, an A-pillar, an outboard region of a hood, or a fender.

First claim

What is claimed is:

1. A product comprising:
an airbag having an inflator assembly, wherein at least a portion of the inflator assembly moves vertically to release a hood hinge mechanism upon deployment and which inflates a cushion to provide cushion coverage over at least one of a rearward region of a hood, a lower windshield, an A-pillar, an outboard region of the hood, or a fender.

2. The product of claim 1 wherein one of the inflator assembly or an intermediate piece attached to the inflator assembly contacts a hood structure to release the hood hinge mechanism.

3. The product of claim 1 wherein a portion of the hood hinge mechanism is directly contacted by one of the inflator assembly or an intermediate piece attached to the inflator assembly to release it.

4. The product of claim 1 wherein in an inflated state, the cushion is not compressed between the inflator assembly and the hood when the hood is lifted.

5. The product of claim 1 wherein a portion of the cushion in an inflated state is compressed between the inflator assembly and the hood when the hood is lifted.

6. The product of claim 1 wherein a portion of the airbag cushion deploys below the hood and helps lift it.

7. The product of claim 1 wherein at least a portion of the airbag is located under at least one of the fender or the hood.

8. A product comprising:
a hood hinge;
wherein the hood hinge includes at least one vertical slot which is perpendicular to a hood;
wherein the at least one vertical slot is constructed and arranged to allow for movement of the hood from an unraised position to a raised position;
wherein the hood hinge is constructed and arranged to remain connected to a vehicle body; and wherein the hood hinge is attached to the hood and at least one external device raises the hood from the unraised position to the raised position.

9. The product of claim 8 further comprising at least one of an anti-reverse travel feature or a travel stop on the hood hinge mechanism.

10. The product of claim 8 wherein a portion of the slot is angled to prevent the hood from raising when a front of the hood is contacted when it is in an unraised state.

11. The product of claim 8 further comprising a retention feature to hold the hood in an unraised state.

12. The product of claim 8 further comprising an energy absorption feature which allows the hood to be pushed down in a controlled manner after it has deployed upward.

13. A product comprising:
an airbag which propels a moving member that releases a hood hinge mechanism upon deployment and which deploys a cushion to provide pedestrian protection from at least one of a rearward region of a hood, a lower windshield, an A-pillar, an outboard region of the hood, or a fender, wherein the airbag further comprises an inflator assembly, and wherein the inflator assembly has a portion which moves to release the hood hinge mechanism.

14. The product of claim 13 wherein the inflator assembly further comprises a telescoping nozzle; wherein the telescoping nozzle moves on the inflator.

15. The product of claim 14 wherein the telescoping nozzle is contained within the cushion and pushes on a layer of cushion fabric as it moves and releases a hood hinge mechanism.

16. The product of claim 13 wherein the inflator assembly further comprises an inflator body which is slideably disposed via its attachment to the airbag, and wherein the inflator body physically moves in a controlled manner in its slideable joint.

17. A product comprising:
an airbag which propels a moving member that releases a hood hinge mechanism upon deployment and which deploys a cushion to provide pedestrian protection from at least one of a rearward region of a hood, a lower windshield, an A-pillar, an outboard region of the hood, or a fender; wherein the airbag assembly further comprises an inflator assembly, and wherein a portion of the inflator assembly movement breaks out a plug in an airbag cover.

18. A product comprising:
an airbag which propels a moving member that releases a hood hinge mechanism upon deployment and which deploys a cushion to provide pedestrian protection from at least one of a rearward region of a hood, a lower windshield, an A-pillar, an outboard region of the hood, or a fender, and wherein the hood hinge mechanism has a fastener which one of shears or deforms to enable the hood hinge release.

19. A product comprising:
an airbag which propels a moving member that releases a hood hinge mechanism upon deployment and which deploys a cushion to provide pedestrian protection from at least one of a rearward region of a hood, a lower windshield, an A-pillar, an outboard region of the hood, or a fender, where the airbag further comprises a hood edge protector.
