Deformation element used as bumper assembly of motor vehicle, is provided between cross element and supporting structure whose block dimension is deformed during crash, by degradation of impact forces applied on supporting structure

摘要

The deformation element (2) is provided between front or rear-side cross element (1) and supporting structure (4). A block dimension of supporting structure is deformed during the event of crash, by degradation of impact forces applied on supporting structure. A composite portion (9) in deformation element is formed in combination of fiber-reinforced plastic (FRP) element (5) and sheet metal portion (6).
