Abstract
A foot rest arrangement for wheelchairs includes a telescopic strut structure with an outer (B) and an inner strut (C) axially displaceable inside the outer strut, and a foot rest (A) attached to the free lower end (at 0) of one strut (B) while the opposing free upper end of the other strut (C) is attached to the wheelchair frame or to the forward portion of the chair seat frame, so that the strut structure carries the foot rest at a distance from the chair seat (6), this distance being variable by raising and lowering the foot rest and/or chair seat. Latching means (H,R) are also arranged to lock the struts relative each other, with the foot rest at a given distance from the chair seat. A suitable illustration is FIG. 1.
