Two die cast aluminum backrest supports attach the backrest to the Torsion mechanism. A steel tube is cast into each backrest support for added strength. The back flex is achieved by the Torsion mechanism. It consists of two flat torsion springs captured at both ends by brass bushings which in turn engage with the backrest supports. The Torsion mechanism creates gradually increasing resistance over the full 12 degrees of back flex. Upholstered chairs have partially exposed polypropylene surfaces. Fabric is upholstered over 9/16" foam on the backrest and 1-1/2" foam on the seat.

2. Piretti Stack
Seats and backrests shall be molded compound curved polypropylene with a textured finish. Backrest edges shall have an integral channel into which upholstery is secured. Upholstered chairs shall have partially exposed polypropylene surfaces. Upholstery covers 1/2" foam on the backrest and 3/4" foam on the seat. Molded plastic seat liner covers the seat underside. The back shall tilt 15 degrees. Two hidden lever mechanisms which respond to the user’s weight shall be located in the seat. Each has a double cam action. The rear cam shall be tied to the back structure and shall be set in motion when the occupant leans back. This, in turn, through a spring linkage, shall activate the front cam at a slightly different ratio (1-1/2 to 1). The mechanism shall consist of stamped-steel frame and levers, a steel spring and molded Delrin and nylon components. It shall be calibrated at the factory and shall need no further adjustment.

An optional adjustable back-angle inclination shall also be available in a range from 87 degrees to 100 degrees. The user shall be able to infinitely vary the angle of the inclination of the back by raising a lever. Two hidden lever mechanisms which respond to the user’s weight shall be located in the seat. Each has a double-cam action. The rear cam shall be tied to the back structure and shall be set in motion when the occupant leans back. This, in turn, through a spring linkage, shall activate the front cam at a slightly different ratio (1-1/2 to 1). The mechanism shall consist of stamped- steel frame and levers, a steel spring and molded Delrin and nylon components. It shall be calibrated at the factory and need no further adjustment.
