US Patent 7757804 Pedestrian vehicle collision safety system

An injury mitigation system for a collision between a vehicle and a pedestrian. The invention includes a releasable net-like structure which is deployed from the front of a vehicle to alter the collision dynamics between the vehicle and the pedestrian is disclosed. A release mechanism allows deployment of the net which expands from a small compact size to a large rectangle in a deployed mode, expanding upward by an integrated spring-like structure which then shrouds the front of the vehicle in a short period of time. The system is activated upon sensing an imminent collision at short range in front of the vehicle through use of a motion sensor or other release mechanism.
