DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
Referring now to the figures of the drawing in detail and first, particularly, to FIG. 1 thereof, there is shown a three-dimensional view of a roll bar configuration 10 according to the invention which is illustrated fitted into a motor vehicle. In this case, the roll bar configuration 10 contains two U-shaped roll bars 11, a transverse strut 12 and a connecting element 20 with a receiving opening 21. One end of a roll bar 11 and one end of the transverse strut 12 are accommodated in each case in the receiving opening 21. The connecting elements 20, which are disposed on both sides between the transverse strut and the inner wall of the body, are of mirror-inverted design. The connecting element 20 is fastened to the outer body wall 23 at a contact surface 22. In the exemplary embodiment, the connecting element 20 is first fastened in a form-fitting manner, but additionally by a screw connection 28 to the outer body wall.
The connecting element 20 is supported horizontally via a contact surface 25 and additionally vertically via a contact surface 26 on the inner body wall which is formed, in the exemplary embodiment, by the roof of the engine compartment. In the embodiment shown, no further fastening elements are fitted on the contact surfaces 25 and 26.
The ends of the roll bar 11, which ends face the longitudinal center axis of the vehicle, are fastened in a suitable manner in or to the transverse strut 12. The ends of the roll bars, which point in the direction of the outer body walls, are accommodated in the receiving opening 21 of the connecting element 20, which is illustrated in FIG. 2.
FIG. 3 shows a section through the connecting element 20 along the section line III-III shown in FIG. 2 through the receiving opening 21 and the ends, located therein, of the roll bar 11 and of the transverse strut 12. In this exemplary configuration, the transverse strut 12 can be supported via the end of the roll bar 11 in the connecting element 20 and therefore on the outer body walls 23 in the event of loading in the longitudinal direction (transversely with respect to the longitudinal axis of the vehicle). In this case, use is also made of the transverse stability of the tubular end of the roll bar 11, which is additionally held by the receiving opening. In the event of a loading in which forces occur in the longitudinal direction of the vehicle or on the vehicle in the vertical direction, the forces are transmitted directly or partially via the end of the roll bar 11 into the connecting element and therefore to the vehicle body. Very high forces introduced lead to the deformation of the cross section of the roll bar 11, with the receiving opening 21 of the connecting element 20 likewise undergoing deformation.
FIG. 4 shows the connecting element 20 from the rear of the vehicle as seen in the direction of the front of the vehicle. A bearing 30 of the top, which is integrated in the connecting element 20 and to which the top is rotatably coupled, can be seen in this view. Transverse forces introduced into the top and, in particular, the tensile forces occurring during the opening and closing of the moving vehicle are absorbed by the bearing 30 of the top and are introduced into the vehicle body via the connecting element 20 and via the contact surfaces 22, 25 and 26 thereof. A belt deflecting lever 32 which likewise introduces high forces into the vehicle body in the event of an impact is also shown here.
