However, such additional reinforcement elements are often difficult to install due to the limited installation space and can only partially compensate for the loss of stiffness due to the lack of a solid roof.

Embodiment Construction

[0032] Referring to Figures 1 and 2, a reinforcement device 1 is shown for increasing the torsional rigidity of an automobile 2 in the form of a convertible, wherein the reinforcement device 1 according to Figure 1 has a single reinforcement element 3, whereas the reinforcement device 1 according to Figure 2 The device 1 has two reinforcing elements 3 and 3'. 1 and 2, the reinforcement device 1 is arranged in the direction of travel 4 behind the rollover protection device 5, wherein the reinforcement elements 3 and 3' are arranged substantially horizontally. The task of the stiffening device 1 here is to stiffen the torsional rigidity of the convertible 2 . The reinforcement elements 3 and 3' are therefore connected on the one hand to the rear of the rollover protection device 4 of the motor vehicle 2 and on the other hand to the base plate 6 of the roof retraction device 7 of the motor vehicle 2 (see Figure 10 ).

Abstract

A single-part or multi-part stiffening device for increasing the torsional stiffness of a motor vehicle embodied as a cabriolet, has at least one stiffening element which is connected at one side to a rear side of a rollover protection device and at the other side to a base of a covering shelf of the motor vehicle.

Description

technical field [0001] The invention relates to a stiffening device for increasing the torsional rigidity of a motor vehicle in the form of a convertible. The invention also relates to a motor vehicle equipped with such a reinforcement. Background technique [0002] Convertibles differ considerably in the type of construction of the load-bearing body compared to fully enclosed vehicles such as coupes. Due to the lack of a roof as a reinforcing component, the rigidity of the self-supporting body that is common today must be ensured by strengthening the chassis. Even with a strengthened chassis, the convertible still had problems with torsional rigidity and had to be additionally strengthened in torsional rigidity. However, due to the limited installation space, such additional reinforcement elements are generally difficult to arrange and can only partially compensate for the loss of rigidity that occurs due to the lack of a solid roof. [0003] EP 1 203 679 B1 discloses a ...
