Roll-over protection bar for passenger cars

The innovation concerns a roll-over protection bar for Passenger car, consisting of at least two approximately vertically to be arranged in the area of door pillars of the passenger car Side supports and one to be arranged approximately horizontally under the roof of the passenger car Transverse bracket. The task of the innovation is to provide such a roll-over protection bar with little additional To design weight for particularly high force absorption in rollover accidents. This task solves the Innovation through a diagonal cross bracing, each of the two lower end areas of the side posts against the diagonally opposite front transition areas between the side support and the cross bar supports. This gives the roll-over protection bar a very high level of rigidity in the plane it defines without requiring particularly thick material cross-sections. Especially for sports use of passenger cars with Such a cross bracing with only a slight increase in weight is an increased risk of accidents at high speeds advantageous.

In order to facilitate access to the rear seats of the passenger car outside of sporting activities, the innovation has been implemented provided that the cross brace is releasably attached. For this purpose, the support points of the cross bracing on the roll-over protection bar existing cross bracing butt butt against each other, and Kiemmuffen on which the pipe sockets with the

Connect the ends of the cross bracing and secure in position. In order to avoid dangerous buckling of the cross brace towards the driver if the rollover protection bar is overloaded to be excluded, this has a flat curvature directed towards the rear of the vehicle. from the upper transition areas between the side supports and the transverse bracket extend in the installed position Support struts sloping down towards the rear of the vehicle for securing the roll-over protection bar in its Mounting position.

The drawing shows an embodiment of the innovation. Therein Figure 1 is a side and oblique view of a roll-over safety bar with cross-bracing for a passenger car, and Figure 2 shows a fastening point of the Kreuzverstreuung in Überroii-Schutzt> bow _s

A roll-over protection bar 1 for passenger cars consists of a tube with a circular cross-section. This has an essentially rectangular shape with two side supports 2 to be fastened to the floor approximately vertically in the installation position in the area of door pillars and a transverse bracket 3 to be assigned approximately horizontally under the roof. These are closely matched to the cross-section of the passenger car. A tube extension 4 is welded to the lower end areas 2 of the side supports 2 and the upper transition areas 3 ¹ between the side supports 2 and the transverse bracket 3. The ends of a diagonally positioned cross strut 5 with the same pipe cross-section butt against these pipe sockets 4. A releasable connection of the cross brace 5 with the pipe sockets 4 is made by clamping sleeves 6, each with two

Clamping screws 6 ^{1 are} provided. In order to be able to

To avoid effort 5 towards the driver, the cross bracing is arched towards the rear of the vehicle. In the installed position towards the rear of the vehicle, support bars 7 that slope down towards the rear of the vehicle are welded to the transition areas 3 ^{1 and can be screwed onto the breast strips of the body.}
