Support device, useful as arm rest during surgery, has height adjustable support part for body part capable of adopting various equilibrium states relative to mounting part

摘要

The height of the support part (8) for the body part can be altered to a restricted degree relative to its mounting part (7) when a given weight is exerted on the support part, so that the latter can adopt various equilibrium states relative to the mounting part. A guide mechanism between the support and mounting parts ensures that the support part can move a limited distance in the height direction relative to the mounting part.
