Abstract
A bumper assembly having a movable bumper is disclosed. A crash sensor is attached to the movable bumper. A linkage is provided to attach the movable bumper to a motor vehicle. When the movable bumper is attached to the motor vehicle, the linkage permits the movable bumper to be moved from a first position to a second position that is horizontally displaced from the first position in a direction away from the motor vehicle. Extending the bumper in this manner allows the crash sensor to provide early detection of a collision involving the motor vehicle.
