  • Collision detection device
    Patent number: 11491936
    Abstract: A collision detection device includes an impact absorber and a collision detector. The impact absorber extends along a vehicle width direction between a bumper face and a bumper beam of a vehicle, and is configured to absorb impact by being deformed upon collision of the vehicle. The collision detector extends along the vehicle width direction, includes a lower collision detector and an upper collision detector, and is configured to detect that the collision has occurred by being deformed upon the collision of the vehicle. The upper collision detector has greater flexibility than the lower collision detector.
