Dual purpose working chair has angle adjusting device including yoke accommodating spring and with angle adjusting lever, and transverse rod guided through seat frame, yoke, spring and adjustment plates

摘要

The working chair has an angle adjusting device (30) including a yoke (31) accommodating a spring (38), guided through the seat frame (12) and pivot-connected to an angle adjusting lever (45). A transverse rod (33) is guided through the seat frame, yoke, spring and adjustment plates (41), through which the body height of the user can be adapted for work on a computer because a connecting rod (16) on the seat back can engage in different positioning recesses (15) in oppositely disposed slide openings (13) in the seat frame for the seat back support, and therefore the angle of inclination of the seat back support is adjustable.
