Problems solved by technology

[0005] In the inventor's opinion, a need not well met by previously known and / or commercially available office chairs is a chair back for the entire anatomical back of the user, from the sacrum to the shoulders, in a range The sitting position provides good support
On the other hand, office chairs designed for use by typists have a back support that automatically adjusts about a horizontal pivot, but the back support is relatively small so only the lower back is supported

Embodiment Construction

[0040] The present embodiment has a base 10 of five casters; an air spring strut 12, which is connected to the base 10, and can adjust the height of the whole chair seat unit (seat bottom assembly 14 and seat back assembly 16); and a Seat mounting mechanism 18 mounted on the pillars which allows the entire seating unit to tilt forward and rearward from an upright position and to lock in either the upright or forward tilted position. The seat mounting mechanism also allows the position of the seat bottom 14 to be adjusted forward and rearward, as indicated by small arrow A1, and locked in a desired position. The components described in this paragraph are well known and are commercially available in various special designs from many vendors of office chair components. The base of a chair embodying the invention need not include all of the features described in this paragraph.

Abstract

A chair has a pair of spaced-apart back support mounting members (20r, 20l), a lower back support adapted to support the lower portion of the back of a person seated on the chair and mounted on the back support mounting members for pivotal movement about a pivot axis (LA) located at substantially the vertical centerline of the lower back support, and an upper back support (42) adapted to support the upper portion of the back of a person seated on the chair and mounted on the back support mounting members for pivotal movement about a pivot axis (UA) located at substantially the vertical centerline of the upper back support.

Description

technical field [0001] The present invention relates to chairs. Background technique [0002] The rapid development of the "new economy" in recent years requires office workers of all levels to spend more time working on computers. Using a keyboard is no longer the domain of a typist / secretary or word processing system operator. Managers often communicate via e-mail and access corporate data and Web sites for the information they need to do their jobs. The design and development of products, purchasing, marketing, production, shipping, and virtually all other activities in industry and commerce are performed with the assistance of computers. Professionals also use computers to obtain information, communicate, and generate documents and computer data files. [0003] Sitting upright with a slight forward lean to operate the keyboard creates considerable muscle tension on the back and is highly tiring. Minimizing muscle tension and fatigue requires a chair that provides ver...
