Abstract: A hood and bumper assembly of a vehicle includes a hood assembly, and a hinge about which the hood assembly rotates between an open position and a closed position. A bumper bracket is secured to a fixed support of the vehicle, and a bumper is located between the bumper bracket and the hood assembly to absorb an impact force of the hood assembly. The bumper bracket is configured to release from the fixed support when the impact force exceeds a preselected threshold to dissipate the impact force. A bumper assembly for a hood of a vehicle includes a bumper bracket secured to a fixed support of the vehicle, and a bumper positioned between the bumper bracket and the hood to absorb an impact force. The bumper bracket is configured to release from the fixed support when the impact force exceeds a preselected threshold to dissipate the impact force.

Abstract: A hood assembly of a vehicle includes a hood outer panel defining an outer surface of the hood assembly, and a hood inner panel defining an inner surface of the hood assembly, such that a hood cavity is defined between the hood inner panel and the hood outer panel. An energy absorbing material is located at the hood inner panel. The energy absorbing material includes a multi-cellular structure formed from a plurality of interconnected cells having a lattice structure. Each of the plurality of interconnected cells includes at least four nodes and at least one lattice element extending between each of the at least four nodes. The at least one lattice element has a diameter no greater than 2.5 mm.

Abstract: A supplemental energy absorber is provided for a vehicle having a hood subjectable to an external force event and a body structure including a primary hood stop. The supplemental energy absorber includes a spring portion and a resilient portion. The spring portion is attachable to the body structure. The resilient portion is attached to the spring portion. The supplemental energy absorber is configured to cooperate with the hood and the primary hood stop to supplement energy absorption during the external force event.
