Abstract
Abstract Elongated hollow structural energy-absorbing parts lying in a fore-and-aft direction are disposed closely adjacent and parallel on the engine hood or luggage compartment lid, and on the body, so that under impact conditions these parts collapse in associated manner, so that the hood or lid contributes to absorbing impact energy without material distortion from its normal plane, while remaining closed. There is provision for relative displacement involving a wedging action, between the hollow parts on the hood or lid and those on the body.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
In a vehicle body having a body compartment including an exterior opening and a pivoted exterior closure received within the body compartment opening, the combination comprising, spaced pairs of generally elongated energy absorbing members extending generally longitudinally of the body, the members each having a vertical face, one member of each pair being mounted on and in addition to the body compartment and the other member of the pair being mounted on and in addition to the closure, with the vertical faces of the members located in adjacent laterally juxtaposed relationship, each pair of energy absorbing members and the closure and body compartment collapsing longitudinally of the body under longitudinal impact loads applied thereto, the vertical faces of the members deforming laterally of the body into wedging engagement with each other upon such collapse, the wedging engagement of the pairs of members laterally interlocking the closure and the body compartment and maintaining the closure within the body compartment opening.
Claim 2
Dependent Claim
159 words
In a vehicle body having a body compartment including an exterior opening and a pivoted exterior closure received within the body compartment opening, the combination comprising, spaced pairs of generally elongated energy absorbing members extending generally longitudinally of the body, the members each having a vertical face, one member of each pair being mounted on and in addition to the body compartment and the other member of the pair being mounted on and in addition to the closure, with the vertical faces of the members located in adjacent laterally juxtaposed relationship, each pair of energy absorbing members and the closure and body compartment collapsing longitudinally of the body under longitudinal impact loads applied thereto, the vertical faces of the members deforming laterally of the body into wedging engagement with each other upon such collapse, the wedging engagement of the pairs of members laterally interlocking the closure and the body compartment and maintaining the closure within the body compartment opening.
Claim 3
Dependent Claim
180 words
In a vehicle body having a body compartment including an exterior opening and a pivoted exterior closure received within the body compartment opening, the combination comprising, spaced pairs of generally elongated energy absorbing members extending generally longitudinally of the body, each member including a hollow elongated structure substantially filled with compressible plastic foam and having a vertical face, one member of each pair being mounted on and in addition to the body compartment and the other member of the pair being mounted on and in addition to the closure, with the vertical faces of the members located in adjacent laterally juxtaposed relationship, each pair of energy absorbing members and the closure and body compartment collapsing longitudinally of the body under longitudinal impact loads applied thereto, the vertical faces of the members being deformed laterally of the body into wedging engagement with each other under the pressure of the plastic foam being compressed within the elongated structures, the wedging engagment of the pairs of members interlocking the closure and the body compartment and maintaining the closure within the body compartment opening.
Claim 4
Dependent Claim
180 words
In a vehicle body having a body compartment including an exterior opening and a pivoted exterior closure received within the body compartment opening, the combination comprising, spaced pairs of generally elongated energy absorbing members extending generally longitudinally of the body, each member including a hollow elongated structure substantially filled with compressible plastic foam and having a vertical face, one member of each pair being mounted on and in addition to the body compartment and the other member of the pair being mounted on and in addition to the closure, with the vertical faces of the members located in adjacent laterally juxtaposed relationship, each pair of energy absorbing members and the closure and body compartment collapsing longitudinally of the body under longitudinal impact loads applied thereto, the vertical faces of the members being deformed laterally of the body into wedging engagement with each other under the pressure of the plastic foam being compressed within the elongated structures, the wedging engagment of the pairs of members interlocking the closure and the body compartment and maintaining the closure within the body compartment opening.
