Abstract:
A height and pivotal adjustable office chair arm assembly having an arm rest assembly thereon and comprising:an arm support having one end for attaching the arm chair assembly to a chair and having an opposite end; a gas cylinder associated with said arm support for movement in the vertical direction to raise and lower the arm rest assembly to any selected vertical position; a shroud surrounding, and vertically removable in relation to, at least a portion of said arm support and having an upper end; said shroud being connected to said gas cylinder for vertical movement by said cylinder; an arm rest pivot support attached only to said shroud for receiving said arm rest assembly and enabling said arm rest assembly to pivot in the horizontal plane, thereby allowing said arm rest assembly to assume any selected rotational position; a hollow tube for slidably receiving said arm support; and a cross-sectional shape that conforms to the cross-sectional shape of the arm support and being such that the shroud can move vertically with respect to the arm support but is non-rotatable with respect to the arm support.
