Abstract
An automobile hood including an exterior show surface and an interior surface facing away from the exterior show surface. At least one expansible gas receiving chamber in fluid communication with an inflator for generating inflation gas is disposed in underlying relation to the interior surface. The placement and expansive character of the gas receiving chamber is such that upon expansion of the gas receiving chamber, the exterior show surface and the corresponding interior surface of the hood are forced outwardly by the gas receiving chamber. The forced movement gives rise to an extended surface profile thereby leading to enhanced impact energy absorption.
Claims22
An automobile hood assembly for disposition in overlying relation to a vehicle storage compartment, the hood assembly including a hood surface structure including an exterior show surface and an interior surface facing away from the exterior show surface, the automobile hood assembly comprising:
- at least one expansible gas receiving chamber adapted to be fluid communication with an inflator for generating inflating gas, the gas receiving chamber comprising a cavity between the interior surface of the hood surface structure and a gas containment member disposed in underlying relation to the interior surface of the hood surface structure and connected to the hood surface structure such that upon introduction of inflating gas into the gas receiving chamber, the gas receiving chamber undergoes expansion thereby causing the hood surface structure to move outwardly away from the vehicle storage compartment.
An automobile hood assembly for disposition in overlying relation to a vehicle storage compartment, the hood assembly including a hood surface structure including an exterior show surface and an interior surface facing away from the exterior show surface, the automobile hood assembly comprising:
- a framework of support members in connective relation to the hood surface structure and extending across at least a portion of the interior surface, a gas receiving chamber disposed between at least a portion of the support members and the interior surface of the hood surface structure, wherein the gas receiving chamber is adapted to be in fluid communication with an inflator for generating inflating gas such that upon introduction of inflating gas into the gas receiving chamber, the gas receiving chamber undergoes expansion thereby causing the hood surface structure to move outwardly away from the vehicle storage compartment and wherein an expansively deformable pleat structure extends between at least a portion of the support members and the hood surface structure such that upon expansion of the gas receiving chamber, the expansively deformable pleat structure is at least partially straightened.
An automobile hood assembly for disposition in overlying relation to a vehicle storage compartment, the hood assembly including a hood surface structure including an exterior show surface and an interior surface facing away from the exterior show surface, the automobile hood assembly comprising:
- a framework of support members in connective relation to the hood surface structure and extending across at least a portion of the interior surface, at least one expansible gas receiving chamber adapted to be in fluid communication with an inflator for generating inflating gas, the gas receiving chamber disposed in underlying relation to at least a portion of the support members such that upon introduction of inflating gas into the gas receiving chamber, the gas receiving chamber undergoes expansion thereby applying force to the support members and causing the hood surface structure to move outwardly away from the vehicle storage compartment.
