Problems solved by technology

However, in order to be able to provide a sufficient adhesive force between the viscous seal and the bonding surface on the body side, the body must be cleaned manually in a rather expensive manner, for example using a textile soaked in a cleaning solution. side bonding surface

Embodiment Construction

[0030] attached figure 1 Shown is a sectional view of a sealing device 10 which has a total of two seals 12 , 42 which are designed as primary and secondary seals, for example for sealing a door gap in a motor vehicle body. The motor vehicle body has two body steel sheets 24, 26 adjoining the edge section to be sealed, and these body panels 24, 26 form the edge section 25 together with flange sections 28, 30 designed to cooperate with each other. The main seal 12 is attached to this edge section 25 , for example by adhesive bonding.

[0031] The seal 12 has an approximately L-shaped fastening section 14 and a hollow-shaped sealing section 20 . In this case, the fastening section 14 and the sealing section 20 can be produced from different plastic or rubber-based materials, it being advantageous for the sealing section 20 to have a higher elasticity than the fastening section 14 .

[0032] The fastening section 14 has a fastening leg 16 which is adhesively fastened by means o...

Abstract

An assembly method and a motor vehicle body having at least one marginal portion delimiting a bodywork opening is provided. The motor vehicle includes a plasma-treated gluing surface to which a seal is fastened in a materially joined manner.

Description

technical field [0001] The invention relates to a motor vehicle body and a seal fixed thereto in a materially connected manner. Background technique [0002] The edge section of the body opening is typically provided with a sealing device. For example, the edge section that delimits the door frame of the body is provided with a primary seal, while the door leaf corresponding to the door frame (Türausschnitt) of the body is provided with a secondary seal, both seals when the door is closed against each other against the respective body parts. [0003] Common seals have a flexible, for example hollow or tube-shaped sealing lip and a fastening section connected to the sealing lip, which can be connected in different forms and in different ways to the door frame edge section. The body-side flanges are connected, for example, in a form-fitting or materially bonded manner. [0004] Prior art DE 10 2006 060 391 A1 discloses a sealing device, for example for sealing motor vehicle...
