specific Embodiment approach

[0033] exist figure 1 , schematically shows a fastening device according to the invention in a normal state (left-hand diagram) and in an accident state (right-hand diagram).

[0034] The fastening device comprises a component 1 , ie a drive battery or another energy storage device, which is fastened in the vehicle, ie to a load-bearing structural element 2 of the vehicle, such as a beam, by means of a screw connection (as fastening means 3 ). The screw connection consists of a screw with a head and a nut plate 7, wherein the head rests on the surface of the part 1 facing away from the beam and the nut plate 7 rests on the surface of the beam 2, so that the beam 2 and the battery 1 are at least as shown in the left figure are pressed against each other in normal conditions (ie normal operating conditions of the vehicle).

[0035] The clamping elements 4 . 1 , 4 . 2 are arranged between the surface of the component 1 facing the load-bearing structure element 2 and the fastenin...

Abstract

The invention relates to a fastening device for a component (1) in a vehicle, comprising the component (1), a load-bearing structural element (2) of the vehicle and at least one fastening means (3), wherein the component (1) is At least one fastening means (3) is fastened to the load-bearing structural element (2), wherein the fastening means (3) has clamping elements (4.1, 4.2), wherein, in the normal state, the clamping elements (4.1, 4.2) enhancing the fastening of the component (1) via the fastening means (3), wherein, under the action of an external force (F), the clamping element (4.1, 4.2) is automatically switched to the accident state, In an accident state, the clamping elements (4.1, 4.2) loosen the fastening of the component (1) via the fastening means (3).

Description

technical field [0001] The invention relates to a fastening device for a component in a vehicle, comprising the component, a load-bearing structural element of the vehicle and at least one fastening means, wherein the component is fastened to the load-bearing structural element of the vehicle by means of the at least one fastening means. Background technique [0002] The fastening of components to the load-bearing structural elements of the vehicle is necessary and common to the construction of the vehicle as a movable unit. The load-bearing structural elements of the vehicle generally form its body. Usually, the fastening to the body is carried out by screw connections. [0003] However, in the event of an accident due to the stiffness of the connection, the tightened components can lead to undesired block formation and high load peaks for occupants and damage safety-critical components. [0004] In order to reduce the possible consequences of an accident, different measu...
