  • Patent number: 8361552
    Abstract: In a method of applying a firmly adhering metallic coating onto a steel sheet product, a steel sheet product is inserted into a film bag which contains at least a coating material. Subsequently, the film bag is evacuated to cause the film to evenly bear upon the outer surface of the steel sheet product. This state is fixed by sealing the film bag. The film bag and the steel sheet product are then subjected to a heat treatment to thereby form a coating of the coating material on the steel sheet product.
    Type: Grant

  • Patent number: 7407206
    Abstract: A bumper structure for a motor vehicle includes a cross member, and a crash box placed between the cross member and a longitudinal member, with the crash box having an attachment zone. Bolts extend through walls of the attachment zone and the longitudinal member for securing the crash box to the longitudinal member by forcing the attachment zone against the wall of the longitudinal member. The attachment zone undergoes hereby locally an elastic or plastic deformation for realizing a self-centered disposition of the crash box in relation to the longitudinal member. The walls of the attachment zone and the longitudinal member extend at a tolerance distance before the crash box is secured to the longitudinal member.
