US 5,348,113 A · Process of and device for more effective use of the deformation zone of motor vehicle bodies

Abstract

More effective use of the deformation zone for the absorption of the impact energy in a vehicle body of graded rigidity is achieved at the moment of deformation of the deformation zone. Pressure by the tyre against the passenger cabin causes its deformation and the tyre gets destructed and deflated, thus allowing for additional deformation of the deformation zone up to the moment of the contact between the rim and the passenger cabin. A destruction member for the tyre is situated in the area of the contact occurring in the deformation zone between the tyre and the passenger cabin. The destruction member may be formed by spikes, punches or cutting edges and is fitted with puncturable covers.

Dependent claims

A device for effective use of a deformation zone of a motor vehicle body having a passenger compartment, the device comprising:

at least one deformation zone attached to the passenger compartment;
at least one vehicle wheel having a rim surrounded by an inflated pneumatic tire, the wheel being located in the deformation zone near the passenger compartment;
at least one destruction member fixed between the passenger compartment and the inflated pneumatic tire of the wheel for puncturing and deflating the tire upon deformation of the deformation zone.
