| 20080224487 | CRASH BOX AND BUMPER FOR A MOTOR VEHICLE - A crash box for placement between a bumper beam and a side rail of a motor vehicle includes a longitudinal profile made of two U-shaped shells having overlapping ends sized to realize a material doubling for increasing side stiffness and to suit the side stiffness to a load level. A flange plate is provided on a side-rail-proximal end of the longitudinal profile and has an opening for passage of the longitudinal profile. The side-rail-proximal end of the longitudinal profile is configured with a collar which is turned outwards. The collar rests against the flange plate and is joined with the flange plate.
