    摘要： Disclosed is single piece molded resin chair shell comprised of a seat member, a back member, and a pair of connecting torsion links. The back of the seat member and the bottom of the back member are separated by a collapsed elliptical shaped opening extending between the connecting torsion links. Each connecting torsion link is comprised of a curved, substantially U-shaped channel preferably provided with a plurality of web members projecting from the base of the channel whereby the connecting torsion links torsionally control the deflection of the back member relative to the seat member when pressure is applied against the back member by the user of the chair.
