  • Support element for absorbing forces in a vehicle
    Patent number: 10046730
    Abstract: A support structure for absorbing forces in a vehicle includes a support element, which encloses a hollow space and includes a number of openings, which is delimited by one or more boundary faces. A receiving body for an assembly unit is inserted in one of the openings so that the receiving body at least partially projects into the hollow space. The receiving body includes a wall which at least in portions runs corresponding to the boundary faces and with which the receiving body makes contact with the boundary faces of the support element.
