Office chair for a computer terminal workstation has a tube which is bent from the rear of the seat into structures to form the armrests and backrest for effective muscular and spinal support

摘要

The office chair, especially for a computer terminal workstation, has a tube which is bent to give the supporting shape for the back and arms. The basic tube bend (2) is horizontal and open to the leading side of the seat and is bent at both sides to form the armrests (4) in an upwards curve. The tube line passes horizontally to the backrest, and then vertically upwards parallel to each other, with a center pinch (5) to allow elbow movement. The tube lines (6) at the center of the backrest are moved outwards at the level of the neck or chin of the seated user, and forwards to give ear pieces. The ends (7) of the tube face each other behind the user's head, with a space between them to take a spring (8).
