Deployable Upper Leg Stiffener for Pedestrian Protection

摘要

A pedestrian safety system for use with a motor vehicle includes a vehicle hood movable between a closed position and a raised position wherein a leading edge of the hood is raised relative to a front surface of the vehicle to form a gap, and a leg stiffener movable between a retracted position wherein it is beneath the hood when the hood is closed and a deployed position wherein the stiffener projects through the gap and is forward of the leading edge of the hood when the hood is raised. At least one actuator mounted beneath the hood moves the stiffener between the retracted and deployed positions. A remote sensing system detects an impending collision with a pedestrian and triggers the raising of the hood and extension of the actuators.
