ABSTRACT:
An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations. The arm support includes an armrest pivotally mounted on a slide or a shroud for sliding the armrest to and away from a base which is secured to a table or chair. The slide or shroud is pivotally mounted in the base such that the armrest, which is pivotal relative to the slide or shroud and slidable to and away from the base, is also rotatable about the base to provide for a wide range of fluid motion for the forearm. The armrest further includes a plurality of roller bearing arrangements for facilitation of the slide or shroud and arm support. The roller bearing arrangements engage the slide or shroud proximate to the housing to provide for the fluid movement of the slide or shroud. A shroud may also be provided for enclosure of the roller bearing slide arrangement to prevent inadvertent engagement between an individual and/or the individual's clothes and the slide.
