Title:
POP-UP HOOD DEVICE HAVING PLASTICALLY DEFORMING ARM
Document Type and Number:
Japanese Patent JP2008120337
Kind Code:
A
Abstract:

To provide a pop-up hood device capable of absorbing energy in a collision with a pedestrian by plastically deforming an arm itself for supporting a hood.

This pop-up hood device 1 has an actuator 10, an energy absorbing arm 30 and a hood lifting arm 40, and is constituted so that the hood lifting arm 40 rises upward with a first hinge part 41 as a fulcrum by being pushed up by the energy absorbing arm 30, and characterized in that when a load is applied from above to the hood lifting arm 40 in the rising state of the hood lifting arm 40, a stress value larger than a yield point of the energy absorbing arm 30 is generated in the energy absorbing arm 30, and a stress value smaller than a yield point of the hood lifting arm 40 is generated in the hood lifting arm 40.
