Abstract
A spring element, especially a torsion dampener, is provided, especially for apparatus for raising and lowering windowpanes of motor vehicles. The spring element includes an outer ring, and an inner ring that is concentric to the outer ring. At least one spoke-like element monolithically interconnects the outer and inner rings, with the outer ring, the inner ring and the spoke-like elements all being made of the same material. At least one member of elastomeric material is disposed between and adheres to both the outer and the inner ring. The material of the outer ring, the inner ring and the spoke-like elements is considerably harder than that of the member of elastomeric material.
