Document Type and Number:
WIPO Patent Application WO/2013/113835
Kind Code:
A8
Abstract:
The invention relates to a flat seal having a sealing plate (10), which has at least two sealing layers (16, 18) arranged one on top of the other and in which at least one passage opening (12) to be sealed is formed. The sealing plate has at least one supporting device (20, 22) that increases the total material thickness of the sealing plate in some areas and that is formed by several folded-over sealing layer sections(161, 181). According to the invention, in order to be able to simply and economically create a supporting device having locally different effective heights, such a flat seal is designed in such a way that the sealing plate (10) has at least one first sealing layer (16) having at least one first layer area in which the first sealing layer (16) has a first layer thickness and in which at least one first folded-over sealing layer section (161) of a supporting device is formed, and the sealing plate has at least one second sealing layer (18) having at least one second layer area in which the second sealing layer has a second layer thickness and in which at least one second folded-over sealing layer section (181) of said supporting device is formed, wherein the first and the second layer thickness are different from each other, such that said supporting device (20, 22) has different total material thicknesses in some areas.
