An anti-crash safety device includes a supporting frame for securely mounting to a vehicle body and an impact rebounding unit which includes at least a resilient reinforcing member supported by the supporting frame at a position spaced apart from the vehicle body for shielding at least a portion of the vehicle body and at least a shock absorbing element rearwardly extended from the resilient reinforcing member. The resilient reinforcing member is adapted to retain a restoring force for bounding an impact force away from the vehicle body when the impact force is applied on the resilient reinforcing member. The shock absorbing element is adapted for applying an urging force to absorb the impact force from the resilient reinforcing member so as to minimize the impact force transmitting from the resilient reinforcing member to the vehicle body and to protect the vehicle body from being crashed by the impact force.
A vehicle body rigidity control apparatus is equipped with a U-shape member substantially becoming a U-shape, a base member for supporting both ends of the U-shape member, and a constraint element for constraining a deformation of the U-shape member in a substantially orthogonal direction for a collision load and releasing the constraint.
