  • Patent number: 8307935
    Abstract: In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position. Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.

  • Patent number: 7975797
    Abstract: In a configuration in which a rod is extended by an actuator and raises a hood at a time of a collision with a collision body, when a collision load greater than a predetermined value is input to near a hood pushed up area, the collision energy is efficiently absorbed. In a state in which a hood (12) is maintained in a pushed up position, when a collision load equal to or greater than a predetermined value is input from a hood upper side, a distal end portion (54) of a rod (20) slides towards a vehicle rear side along a pushed up surface (38) of a hood rear portion, while deforming the rod (20) by bending, thereby absorbing collision energy. At this time, before a base of a hinge arm (30) contacts a cowl top side (22), distal end portion (54) of rod (20) catches against a bending portion (60) such that rod (20) is bent further.
