Problems solved by technology

In this case, there is a disadvantage that not only dirt easily penetrates into the structure of the sealing part in this way
Such a situation not only has a very adverse effect on the appearance of the sealing strip (depending on the local distortion, which appears as the result of uneven distribution of tensile forces), but also locally produces very large mechanical stresses. stress, which will shorten the life of the part

Embodiment Construction

[0018] The profile is a side-by-side structure, which is arranged side by side by a hollow profile-shaped sealing part 1, a U-shaped fastening part 2, and a strip 3 formed on the side of the fastening part 2, wherein the strip 3 mainly constitutes the covering plate.

[0019] A similar U-shaped metal reinforcement 4 is provided on the fastening part 2 and is to be positioned on a flange (not shown in the figure) which is attached to the edge of the opening in the vehicle. In order to stabilize the fitting of the fastening part 2 on this flange, flexible tongues 5, 6 are provided on the inner surface of the fastening part, which generally extend from the right branch 2' in a mutual direction. Parallel spacings extend out and, relative to the U-shaped profile of the fastening part 2 , inwards in the direction towards the profile base 2 ″. In addition, on the inside of the fastening part 2 opposite the flexible tongues 5 , 6 Above, a saw-tooth-shaped structure 7 is provided, whi...

Abstract

The invention relates to a weatherstrip, which is to be placed onto the flange of the edge of the opening of a vehicle and which is made of a side-by-side arrangement of a tubular sealing section (1), of a U-shaped fastening section (2) and of a strip (3), which is shaped onto the side of the fastening section (2) and which, together with a limb (2') of the fastening section (2), circumscribes a cavity (9 ) open toward the underside (1') of the weatherstrip. The cross-sectional profile of the sealing section (1) is partially formed by the limb (2''') of the fastening section (2) facing the former. Ventilation holes (18) are located on the underside of the weatherstrip, which faces said edge and which forms an area of the greatest wall thickness of the sealing section (1). This arrangement of the ventilation opening is advantageous in that this results in almost no negative influence upon the flexural rigidity of the cross-sectional profile so that the weatherstrip can also be placed along small radii of curvature without the risk of the profile collapsing. To this end, the ventilation openings are located on an underside facing the edge without having any negative influence upon the visual appearance.

Description

technical field [0001] The invention relates to a sealing strip (weather stripping) according to the preamble of claim 1 . Background technique [0002] There are side-by-side structure sealing strips in the prior art, for example, the applicant’s company provides such products. The sealing strips of this structure are made of hollow special-shaped and / or tubular sealing parts and U-shaped tight parts arranged side by side. Formed as a solid part, such a sealing strip is to be positioned on a peripheral flange, such as a door frame of a motor vehicle. [0003] The design of the fastening part is primarily aimed at the assembly, and it should be designed to be reliable so as not to fall off from the flange accidentally. At the same time, the sealing strip should usually have the function of shock absorption. It achieves this function by forming a buffer zone between metal parts arranged to be relatively movable, such as a door frame and a door edge. In the closed state of t...
