A seal of non-hermetic design for installation between two components which can move relative to one another, includes a multiplicity of flexurally elastic sealing elements which each have an end connected fixedly to a seal-bearing device and a free, angled end with the point directed toward the surface of the one component, the seal-bearing device being connected fixedly to the other component and supporting the angled ends of the sealing elements at least on one side. The sealing elements are designed as thin-walled, angled spring leaves and are arranged parallel next to one another and in at least two layers one above the other with alternate overlapping.
