Support structure of motor vehicle, has secondary material having higher ductility, which is compressible under action of tensile force of flexure support in event of impact, through the joining element for receiving deformation energy

摘要

The structure (1) has a flexure support (10) which is positively secured at joining portions (12a,12b) over a joining element. The flexure support has a primary material and an opening area adjacent to the joining element in opposite direction affecting the flexure support, in the event of tensile force. A secondary material having a higher ductility than the primary material is provided such that under the action of tensile force of the flexure support in the event of an impact, the secondary material is compressible through the joining element for receiving deformation energy.
