Abstract:
1. A crash box for placement between a bumper beam and a side rail of a motor vehicle, said crash box comprising: a longitudinal profile made of two U-shaped shells having overlapping ends sized to realize a material doubling for increasing a side stiffness and to suit the side stiffness to a load level; and a flange plate provided on a side-rail-proximal end of the longitudinal profile and having an opening through which the longitudinal profile passes, wherein the side-rail-proximal end of the longitudinal profile is configured with a collar which is turned outwards and extends in a direction of the longitudinal profile, thereby defining an angle between 20° and 70° between the longitudinal profile and the collar, said collar resting against and joined with the flange plate on a flange plate side distal to the longitudinal profile.
