ABSTRACT:
An improved wheel chair leg rest shock absorption apparatus. The apparatus includes a frame having a telescoping linkage slidably received therein. A leg rest is coupled to the linkage and means are coupled to the linkage for extending and retracting it. A spring assembly is coupled to the leg rest to absorb shock force applied to the leg rest and prevent deformation and damage to the apparatus. The spring assembly absorbs shock regardless of whether the leg rest is raised or lowered.
