Problems solved by technology

[0002] When using cavities enclosed by hollow profiles for arranging structural units, such as seat belt automatics, the following disadvantages arise: on the one hand, arranging the structural units in the cavity requires high installation costs; Design openings in the walls of the profile for the insertion of structural elements into the cavities
However, openings thus designed reduce the strength of the respective supports, requiring additional stiffeners and / or higher material strength or larger dimensions of the supports to compensate for the aforementioned reduction in strength
However, on the one hand, this will increase the complexity of vehicle manufacturing, and on the other hand, it will also increase the weight of the vehicle, which is not conducive to simplifying the manufacturing process and reducing fuel consumption.
In addition, larger dimensions for the supports involved also require more construction space, which in turn reduces the luggage compartment or passenger compartment space of the vehicle

Embodiment Construction

[0041] figure 1 The first profile part 10 of the support part 12 according to the invention is shown in a cutaway form, wherein the first profile part 10 extends along the longitudinal axis L and is designed approximately L-shaped. The first profile part 10 is in figure 1 A lower plane 14 and a rear plane 16 are formed in the schematic diagram of the drawing, which have folded-over end sides 18 at their free ends.

[0042] The first profile part 10 comprises an opening 20 which, in the schematic illustration, lies mainly on the rear plane 16 and has a rectangular shape. The opening 20 is delimited by a delimiting surface 22 , in this case extending along a longitudinal axis L of a first delimiting surface 24 and a first, second delimiting surface 26 , which are formed by the folded edges of the first profile part 10 . However, the delimiting surface 22 can also be formed by the wall of the support part 12 itself. The opening 20 opens towards the folded-over end side 18 of t...

Abstract

The present invention relates to a support structure for absorbing forces in a vehicle, comprising a support element 12, which encloses a hollow space 62 and comprises a number of openings 20, which is delimited by one or more boundary faces 22, a receiving body 32 for an assembly unit 34, which is inserted in one of the openings 20 so that the receiving body 32 at least partially projects into the hollow space 62, wherein the receiving body 32 comprises a wall 38 which at least in portions runs corresponding to the boundary faces 22 and with which the receiving body 32 makes contact with the boundary faces 22 of the support element 12. In addition, the invention relates to a corresponding receiving body, to a vehicle, which is equipped with such a support structure and to a method for assembling this support structure.

Description

technical field [0001] The invention relates to a support structure for absorbing forces in a vehicle. Such a frame structure of a vehicle comprises a plurality of support elements, such as longitudinal and cross members as well as strut elements, which can be connected to one another in various ways as required. Usually the cross-section of the support is made of an open or closed hollow profile, thus enclosing the cavity. As a result, the structural unit can be arranged in this cavity, so that the naturally occurring space already present in the vehicle can be fully utilized. Background technique [0002] When using cavities closed by hollow profiles for arranging structural units, such as seat belt automatics, the following disadvantages arise: on the one hand, the arrangement of structural units in the cavity requires high installation costs, and on the other hand, it requires Openings are designed in the walls of the profile for the insertion of structural elements in...
