Abstract
Abstract According to the invention a vehicle has a panel with an opening through which an air bag is deployed. An air bag deployment door closes the opening in the panel. Upon air bag deployment, the door is forcibly moved out of the opening from a closed position towards an open position by the deploying air bag. A hinge for the deployment door includes a door hinge element carried by the door, and a vehicle hinge element carried by the vehicle. The separate hinge elements have cooperating hinge-forming features which are spaced apart from one another when the door is in the closed position. Upon air bag deployment, the door begins to lift out of the opening and carries the door hinge element into engagement with the vehicle hinge element to hingedly interconnect the cooperating hinge-forming features, thereby anchoring the door to the vehicle and limiting further movement of the door to rotation about an axis defined by the hinge elements. In accordance with this invention, one of the hinge elements may include a hooked leg while the other hinge element may include an apertured leg. The hook and aperture provide cooperating hinge-forming features that form a hinged interconnection upon air bag deployment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
In a vehicle having a cover with an opening through which an air bag is deployed, and a door closing the opening and being forcibly moved out of the opening from a closed position towards an open position by the deploying air bag, the improvement comprising: a door hinge element carried by the door, a vehicle hinge element carried by the vehicle, said hinge elements having cooperating hinge-forming features spaced apart from one another when the door is in the closed position and said door hinge element being carried by the door into engagement with said vehicle hinge element causing the cooperating hinge-forming features to hingedly interconnect and anchor the door to the vehicle whereby further movement of the door towards the open position is limited to the door rotating about an axis defined by said hinge elements.
Claim 2
Dependent Claim
138 words
In a vehicle having a cover with an opening through which an air bag is deployed, and a door closing the opening and being forcibly moved out of the opening from a closed position towards an open position by the deploying air bag, the improvement comprising: a door hinge element carried by the door, a vehicle hinge element carried by the vehicle, said hinge elements having cooperating hinge-forming features spaced apart from one another when the door is in the closed position and said door hinge element being carried by the door into engagement with said vehicle hinge element causing the cooperating hinge-forming features to hingedly interconnect and anchor the door to the vehicle whereby further movement of the door towards the open position is limited to the door rotating about an axis defined by said hinge elements.
Claim 3
Dependent Claim
212 words
In a vehicle having a cover with an opening through which an air bag is deployed, and a door closing the opening and being forcibly moved out of the opening from a closed position towards an open position by the deploying air bag, the improvement comprising: a door strap carried by the door having a first leg underlying and attached to the door and a second leg extending from the first leg, said door strap being bendable about a bending axis defined by the folded intersection of said first and second legs, a door hinge element carried by the second leg of the door strap, a vehicle hinge element carried by the vehicle, said hinge elements having cooperating hinge-forming features spaced apart from one another when the door is in the closed position and upon air bag deployment the door being forcibly moved from the closed position towards the open position carries said door hinge element into engagement with said vehicle hinge element causing the cooperating hinge-forming features to hingedly interconnect and anchor the door to the vehicle whereby further movement of the door towards the open position is limited to the door rotating about an axis defined by said hinge elements and bending about an axis defined by said door strap.
Claim 4
Dependent Claim
212 words
In a vehicle having a cover with an opening through which an air bag is deployed, and a door closing the opening and being forcibly moved out of the opening from a closed position towards an open position by the deploying air bag, the improvement comprising: a door strap carried by the door having a first leg underlying and attached to the door and a second leg extending from the first leg, said door strap being bendable about a bending axis defined by the folded intersection of said first and second legs, a door hinge element carried by the second leg of the door strap, a vehicle hinge element carried by the vehicle, said hinge elements having cooperating hinge-forming features spaced apart from one another when the door is in the closed position and upon air bag deployment the door being forcibly moved from the closed position towards the open position carries said door hinge element into engagement with said vehicle hinge element causing the cooperating hinge-forming features to hingedly interconnect and anchor the door to the vehicle whereby further movement of the door towards the open position is limited to the door rotating about an axis defined by said hinge elements and bending about an axis defined by said door strap.
Claim 5
Dependent Claim
193 words
In a vehicle having a cover with an opening through which an air bag is deployed and a door closing the opening and being forcibly moved out of the opening from a closed position towards an open position by the deploying air bag, the improvement comprising: a door hinge element having a mounting leg attached to the door and an engaging leg extending from the mounting leg, a vehicle hinge element having a vehicle leg attached to the vehicle and an engaging leg extending from the vehicle leg, said engaging leg of the vehicle hinge element overlapping and spaced above said engaging leg of the door hinge element when the door is in the closed position, one of said engaging legs having an aperture and the other having a hook, whereby upon air bag deployment said engaging leg of the door hinge element being carried by the door into engagement with said engaging leg of the vehicle hinge element causes said engaging legs to hingedly interconnect and anchor the door to the vehicle limiting further movement of the door towards the open position to rotation about an axis defined by said hinge elements.
Claim 6
Dependent Claim
193 words
In a vehicle having a cover with an opening through which an air bag is deployed and a door closing the opening and being forcibly moved out of the opening from a closed position towards an open position by the deploying air bag, the improvement comprising: a door hinge element having a mounting leg attached to the door and an engaging leg extending from the mounting leg, a vehicle hinge element having a vehicle leg attached to the vehicle and an engaging leg extending from the vehicle leg, said engaging leg of the vehicle hinge element overlapping and spaced above said engaging leg of the door hinge element when the door is in the closed position, one of said engaging legs having an aperture and the other having a hook, whereby upon air bag deployment said engaging leg of the door hinge element being carried by the door into engagement with said engaging leg of the vehicle hinge element causes said engaging legs to hingedly interconnect and anchor the door to the vehicle limiting further movement of the door towards the open position to rotation about an axis defined by said hinge elements.
