ABSTRACT:
A rocking chair has a base frame fitted with mounting brackets adjacent the floor to which lower ends of support legs of a chair frame are secured to enable a chair frame to rock about a transverse rocking axis closely adjacent the floor. A spring shock assembly is mounted beneath the seat portion and is coupled at its upper end directly to the chair frame and at its lower end to the forward arm of a reaction lever pivoted to the base frame. A rearward arm of the lever is coupled by a rigid tie rod to the back of the chair frame. The spring shock biases the chair frame constantly forwardly and is overcome when a person is fully seated and leans back in the chair causing it to rock rearwardly. The shock dampens the movement of the chair. The leverage applied to the spring shock can be adjusted by adjusting the longitudinal position of attachment of the tie rod.
