Embodiment Construction

[0033] figure 1 A portion of a motor vehicle structure 1 is shown in which an embodiment of the invention may be adapted for releasably connecting the rear end of a front subframe 2 to a motor vehicle body 3 . The motor vehicle structure 1 is of unitary construction. The front subframe 2, which forms part of the motor vehicle front structure 1a, comprises longitudinally and transversely extending structural components. Normally, the front subframe 2 is connected to the vehicle body 3 with four connection points: two at the front end of the front subframe 2 and two at the rear end of the front subframe. The motor vehicle front structure 1 a also comprises a foldable structural part 6 which is suitable for forming a deformation region 7 in which the energy of the impact is absorbed during the impact.

[0034] figure 2 A schematic diagram of a front subframe 2 in one embodiment of the invention is shown, the rear end 2a of which is connected to a motor vehicle body 3 via a co...

Abstract

The present invention relates to a connecting device (8) arranged in a motor vehicle (1) for releasably connecting a structural member (2) of the vehicle (1) to the vehicle chassis (3), said connecting device (8) comprising a bolt joint system (9). The connecting device (8) further comprises a pyrotechnical charge (23) and an igniter (23), said igniter (23) being adapted to, when receiving an ignition signal, bring said pyrotechnical charge (23) to detonate, said pyrotechnical charge (23) being located near the bolt joint system (9) such that it, upon detonation, destroys the connecting function of the bolt joint system (9), for releasing said structural member (2) from the chassis (3).

Description

technical field [0001] The invention relates to a connection device arranged on a motor vehicle for the releasable connection of a structural part of the motor vehicle to a body of the motor vehicle, said connection device comprising a screw connection system. [0002] The invention also relates to a method for controlling a connecting device provided on a motor vehicle for releasably connecting a structural component of the motor vehicle to the body of the motor vehicle. Background technique [0003] In automotive vehicle design, the energy absorption characteristics of the vehicle's structure in a crash situation are an important consideration. In the event of a crash, the motor vehicle occupants are subjected to crash loads which can lead to serious injuries. The crash loads are, for example, the result of high accelerations during the crash. The level of acceleration experienced by passengers during a crash is heavily influenced by the structural stiffness of the vehic...
