Abstract:
1. A multi-layer gasket which comprises at least one first layer and one second layer and a plurality of connecting arrangements for connecting the first layer and second layer of the gasket together, wherein each connecting arrangement comprises at least one retaining element connected to one of the first layer or second layer and at least one through opening disposed in the other of the first layer or second layer, wherein each retaining element and a respective retention area adjoining the respective through opening of each of the connecting arrangements partially overlap one another in an unconnected state of the first layer and second layer, wherein, for the purposes of connecting the first layer and second layer, each retaining element is deformable from a plane of the one of the first layer and second layer to which it is connected in such a manner that it is moved to penetrate the respective through opening past the respective retention area wherein the retaining element of at least one of the connecting arrangements comprises a one-piece retaining tongue connected at one end to one of the first layer or second layer, said retaining tongue having at least two mutually spaced overlapping areas which overlap respective retention areas of the adjoining through opening in the unconnected state of the first layer and second layer and deform during the movement of the retaining tongue past the retention areas in such a manner that the retaining tongue can be moved past the retention areas, wherein each retaining element grips behind the respective retention area in a connected state of the first layer and second layer in such a manner that the first layer and the second layer are safeguarded from a separating movement thereof, and wherein an edge of the retaining element of one of the connecting arrangements extends in a first retaining element edge direction where that retaining element penetrates the respective through opening and an edge of the retaining element of another of the connecting arrangements extends in a second retaining element edge direction where that retaining element penetrates the respective through opening, said first retaining element edge direction and said second retaining element edge direction being mutually rotated relative to one another.
