ABSTRACT:
A chair has a base, a generally horizontal seat supported on the base, and a generally vertical back supported on the base behind the seat and provided at a predetermined spacing above the seat with a horizontally extending flex joint having formations for permitting free pivoting backward of an upper portion of the back to a predetermined backwardly deflected position and for thereafter resisting further backward deflection. The back comprises a front plate, a cushion carried on the front plate, and a rear plate fixed to the front plate and formed with the flex joint. The formations include a pair of extending flanges extending generally horizontally from the rear plate and a bight interconnecting the two flanges. The flex joint can be unitarily formed with the rear plate. Its flanges are vertically spaced from each other and only touch when the predetermined backwardly deflected position is reached.
