Abstract
A fixation element and a method for producing such fixation elements for a vibration-insulating assembly of a first component 20 upon a second component 19 is disclosed. The fixation element comprises bearing plates 10, 11 which are positioned at a distance axially spaced from each other and which have projecting snap-in members 13, 18 which are intended to engage corresponding openings defined within each component 19, 20, so that the two components are made to bear in a stable manner against the bearing plates 10, 11. In this respect the snap-in members 13, 18 form an integral part of each bearing plate 10, 11. Moreover, the plates are mutually connected by means of a bridging part 12 of elastomeric plastic material. According to the method, the bearing plates are cast as a single piece 21 within a first casting mold, such that they are connected by at least one breakable bridge 22. The single piece 21 is placed within a second casting mold consisting of two halves 23, 24. The two mold halves are pushed together axially, with axial displacement of one bearing plate with respect to the other, so that the bridge is broken. Finally, an elastomeric plastic material 12 is cast into th…
