Title: Hinge having reproducible bearing friction

Abstract: Two rigid bodies are hinged together by a pair of elastomer hinge elements each of which is fixed within one body and rotatably mounted relative to the other body. At the rotary mounting, the elastomer material is stressed by interengagement with the other body to produce reproducible bearing friction. Properties of the elastomer material are selected to adapt the material for the hinge function; the elastomer element is readily replaceable without the need to replace the rigid bodies.
