Energy absorption device for bumper arrangement of vehicle, has hollow longitudinal section designed for deformation and has rolled-back region attached to hollow longitudinal section

摘要

The energy absorption device (1) has a hollow longitudinal section (2) designed for deformation. A rolled-back region (3) attached to the hollow longitudinal section and a fastening section (4) connected with the rolled-back region. The hollow longitudinal section is aligned in an initial condition before an energy absorption inclined to the axial direction of the fastening section. An independent claim is also included for a method for manufacturing a single piece energy absorption device.
