Problems solved by technology

[0006] However, the disadvantage is that the matching and assembly of this rubber seal is very expensive
Furthermore, also because the rubber seal only offers a limited tolerance compensation, on the one hand the rubber seal can be too tight, which can damage the rubber seal when it is guided through the through-body
On the other hand, if the selected rubber seal is too large, there is a high risk of remaining gaps, which may allow moisture to enter the interior of the vehicle body or airborne sound to the interior of the vehicle body

Embodiment Construction

[0029] Figure 1 shows an end wall 1 of a motor vehicle. The end wall comprises a first wall 2a and a second wall 2b spaced therefrom. A foam material 3 is arranged between the first wall and the second wall. The first wall 2a comprises a corresponding first opening 4a and the second wall 2b comprises a corresponding second opening 4b. A through-body 5 passes through the first opening 4a and the opening 4b flush therewith. At the same time, the foam material 3 is also pressed against the through-body 5 , which embraces the through-body 5 cylindrically in FIG. 1 .

[0030] Between the through-body 5 and the first opening 4a there is a gap 6a filled with foam material.

[0031] In the region of the second opening 4 b between the penetration body 5 and the second wall, a peripheral gap 6 b filled with foam material is provided and likewise overflows from this peripheral gap 6 b.

[0032] The foam material is polyurethane; both the first wall 2a and the second wall 2b are plast...

Abstract

The invention relates to a bulkhead (1) for a motor vehicle, comprising a first wall (2a) and a second wall (2b) at a separation therefrom and a foam (3), arranged between the first and second wall. A first opening (4a) in the first wall and a corresponding second opening (4b) in the second wall are provided for passing a through body (5) which runs through the openings. The foam (3) at least partly contacts the through body (5). A surrounding gap (6a; 6b) is arranged between the through body and the first (2a) and / or second wall (2b) in the region of the corresponding openings (4a; 4b).

Description

technical field [0001] The present invention relates to an end wall (also called "drum panel" or "bulk") of a motor vehicle. Background technique [0002] The principle of motor vehicle end walls is already known. It is a partition wall between the motor space and the vehicle occupant space. The end walls perform a variety of tasks. On the one hand, it is used for stability of the vehicle body (eg against twisting around the longitudinal axis of the vehicle) and, on the other hand, it is used for example for crash safety (in the event of a frontal impact, the protection component penetrates from the motor space into the vehicle interior). In addition, it is also used for thermal and acoustic insulation between the motor space and the vehicle interior. [0003] The end walls may have a "sandwich-like structure". That is, the end wall includes a first wall and a second wall spaced therebetween, and a foam material is disposed between the first and second walls. [0004] ...
