Embodiment Construction

[0041] exist figure 1 and 2 The two-component seal body 10 shown schematically in FIG. 2 has an annular outer seal component 12 surrounded by an inner seal component 14 . The outer and inner sealing components 12 , 14 differ in their material properties. The inner sealing component 14 is, for example, entirely made of a natural or synthetic rubber material, for example EPDM, which is more flexible and elastic than the outer seal 12 , which preferably consists of PUR foam.

[0042] The entire sealing body 10 is fastened to the figure 2 On the dash panel 30 of the motor vehicle which is only schematically shown in FIG. In this case, the sealing body 10 can be secured by means of a clamping fit of the outer sealing component 12 . In this way, it is even conceivable to finally install the sealing body 10 on the vehicle without the aid of tools.

[0043] The outer seal assembly 12 therefore has a base section 32 , by means of which the outer seal assembly can rest on the edge...

Abstract

A seal configuration is provided for sealing an opening of a motor vehicle front wall 30 provided for the passage of heating and / or air-conditioning pipes, such as heating and / or air-conditioning pipes, having a two-component seal body insertable into the opening, which has an outer peripheral edge component 12 made of a first seal material and an inner seal component made of a second seal material. The first and the second seal materials 12, 14 have different moduli of elasticity and / or different acoustic damping properties.

Description

technical field [0001] The invention relates to a sealing device for sealing openings in the bulkhead of a motor vehicle provided for the passage of heating and / or air-conditioning ducts. Background technique [0002] In order to adjust the vehicle passenger compartment to the desired temperature, it is necessary to conduct ducts from the engine compartment of the vehicle into the passenger compartment, whereby water heated, for example, by the waste heat of the internal combustion engine can be fed to a heating element arranged in the passenger compartment, usually air -Water heat exchanger. [0003] The arrangement of the air-conditioning ducts is similar, and the evaporator of the air-conditioning system, which is arranged in the passenger compartment, is connected to the remaining components in the refrigerant circuit via the air-conditioning ducts. [0004] The passage of these ducts through the vehicle's cowl or front wall requires seals, especially to protect the veh...
