  • Impact-sensor mounting structure for an automotive vehicle
    Patent number: 5311963
    Abstract: An impact sensor is mounted to the front portion of a vehicle body so as to operate with a desired responsiveness. The impact sensor is located below a horizontal line passing through the upper end portion of a stiffener for a bumper of the vehicle and behind a vertical line passing through a front end portion of the stiffener. The stiffener is stiffer than a portion of the bumper which is located on a horizontal line passing through the stiffener. Crash energy is not transmitted to the impact sensor during a light crash and, as a result, the air bag is not inappropriately inflated during such a light crash.
