Abstract:
A hood assembly for a vehicle, comprising:a vehicle body having a vehicular hood; and at least one actuator for lifting up a rear end portion of said vehicular hood to a given height to thereby place the hood in a raised position when the vehicle collides with an object to be protected, said actuator including an actuator block mounted to the vehicle body, and a rod vertically disposed in the actuator block and movable in the axial direction thereof to protrude from the actuator block, the rod having a weakened portion having a lower rigidity than the remaining portion of the rod wherein when the actuator is operated in response to collision of the vehicle with the object the rod moves upward to lift up the hood to the raised position, and when the object further encounters a secondary collision with the hood which has been placed to the raised position by the rod, an impact load exerted on the hood causes the weakened portion of the rod to bend and then engage a portion of the actuator block to thereby prevent the rod from moving downward so that the hood is kept in the raised position.
