Abstract
An occupant support includes a framework with a frame and an orientation adjustable deck section that is supported by the frame. A lockable gas spring includes a piston assembly coupled to one of the frame and the deck section and a cylinder coupled to the other of the frame and the deck section. The piston assembly includes a piston and a connecting rod. The piston divides the interior of the cylinder into isolated and non-isolated compartments. The non-isolated compartment has an inlet and an outlet. An outflow check valve operates to resist fluid flow out of the non-isolated compartment and to admit ambient fluid into the non-isolated compartment. An inflow check valve operates to resist fluid flow into the non-isolated compartment and to enable fluid flow out of the non-isolated compartment. A turbine receives fluid that flows out of the non-isolated compartment. An electrical generator is coupled to the turbine.
