ABSTRACT:
A seat is pivotally connected to a frame of a wheelchair and is connected by one or more resilient supports. Each support includes a housing attached to either the seat or the frame and a bracket arrangement attached to the other of those wheelchair components. A spring biases the bracket arrangement with respect to the housing and an adjuster enables the force of the spring to be varied to alter resiliency of the support.
