Abstract:
A patient chair has a support pedestal with a pair of front legs, a pair of rear legs, a pair of side members, a rear frame member connecting the two rear legs and a cross member connecting the side members at a location between the front and rear legs. A pair of leaf springs is attached to the underside of the cross member with portions thereof extending forwardly and rearwardly therefrom in a substantially horizontal manner. Each leaf spring includes a U-shaped bight or loop portion at the forwardmost extremity of the leaf spring coupling the forwardly extending portion with a horizontal overlying portion which passes over the cross member and extends rearwardly therefrom terminating in an orthogonally generally upwardly extending back support portion. A seat is fastened to the horizontal overlying portion of each leaf spring for receiving and supporting a chair occupant. Each leaf spring is provided with two spaced apart resilient members which are fixed to the chair and engage the horizontal overlying portion when the seat is supporting a load. The resilient members contribute to the spring action opposing closing of the U, but not to the spring effect opposing opening of the U.
