US Patent 7850241 Nestable and stackable chair

A chair is provided comprising a seat assembly including a seat back and a seat bottom and a support frame including a left leg assembly and right leg assembly connected by a transverse support member. The seat back is pivotably connected to each of the leg assemblies such that an upper portion of the seat back pivots in relation to the leg assemblies between a first seat back position and a second seat back position. The seat bottom is rotatable in relation to the seat back between an upright position and a horizontal position. The seat bottom is slidingly engaged with the leg assemblies such that pivoting of the seat backward from the first seat back position to the second seat back position causes the seat bottom to slide forward from a first seat bottom position to a second seat bottom position.
