Abstract
The present invention provides a thin vehicle closure panel design that substantially reduces a thickness (panel gauge plus the perpendicular distance or depth between the panels) of a vehicle hood (5) and the impact effect on the head of a pedestrian struck by a motor vehicle. In one embodiment, the vehicle hood (5) includes a hood shell (15) including an outer panel (25) and an inner panel (20); a unitary foam core (100) positioned between and bonded to the outer (25) and/or the inner panel (20) of the hood shell (15); and at least one recess (10) that corresponds to an underhood component (42). In another aspect of the invention, a vehicle hood (5) is provided in which a latch attachment member (60) and/or hinge members (70) are attached to inner surface (50) of the inner panel (20) of the hood shell (15).
