Deformation element, in particular for use in motor vehicles

Abstract

A deformation element, in particular for use in motor vehicles, comprises a first base part and a second base part. The first base part includes at least one protrusion which tapers starting from the first base part. The second base part includes at least one recess which tapers from a front side to a rear side thereof and is associated to the protrusion.

         2 . The deformation element according to  claim 1 , wherein said protrusion has the shape of a truncated cone.  
     
     
         3 . The deformation element according to  claim 1 , wherein said protrusion has the shape of a truncated pyramid.  
     
     
         4 . The deformation element according to  claim 1 , wherein said recess has the shape of a truncated cone.  
     
     
         5 . The deformation element according to  claim 1 , wherein said recess has the shape of a truncated pyramid.  
     
     
         6 . The deformation element according to  claim 1 , wherein a side surface of said protrusion and a middle axis of said protrusion include the same angle as a side surface of said recess and a middle axis of said recess.  
     
     
         7 . The deformation element according to  claim 1 , wherein a side surface of said protrusion and a middle axis of said protrusion include a larger angle as a side surface of said recess and a middle axis of said recess.  
     
     
         8 . The deformation element according to  claim 1 , wherein an angle between a side surface of said protrusion and a middle axis of said protrusion varies.  
     
     
         9 . The deformation element according to  claim 1 , wherein an angle between a side surface of said recess and a middle axis of said recess varies.  
     
     
         10 . The deformation element according to  claim 1 , wherein a cross-section of a front face of said protrusion is smaller than a cross-section of a front surface area of said recess.  
     
     
         11 . The deformation element according to  claim 1 , wherein a cross-section of a foot surface area of said protrusion is larger than a cross-section of a front surface area of said recess.  
     
     
         12 . The deformation element according to  claim 1 , wherein said two base parts are configured like a plate and comprise a plurality of protrusions and recesses, respectively.  
     
     
         13 . The deformation element according to  claim 1 , wherein said second base part is made of a material that is softer than a material of said protrusions.  
     
     
         14 . The deformation element according to  claim 13 , wherein at least one of said base parts is made of a foamed plastics material.  
     
     
         15 . The deformation element according to  claim 1 , wherein one of said base parts is attached to a car body outer part.  
     
     
         16 . The deformation element according to  claim 1 , wherein one of said base parts is attached to a lining piece for a vehicle interior space.
