Abstract

An apparatus allowing a user to adjust a chair, the apparatus comprising: two or more chair parameter adjustment mechanisms, each chair parameter adjustment mechanism configured to allow adjustment ofa separate chair parameter, two or more cams, each cam configured to actuate one of the two or more chair parameter adjustment mechanisms, and a mechanical coupling between the two or more cams, wherein the apparatus is configured such that each of the two or more chair parameter adjustment mechanisms is independently actuatable by the two or more cams.

Description

technical field [0001] The present invention relates to mechanisms for adjusting the position of components of chairs to suit a user, including but not limited to office chairs. Background technique [0002] The office chair has been a ubiquitous piece of equipment in the workplace for decades. As the use of computers by workers has increased, the art has directed increased attention to providing well-designed ergonomic office chairs. [0003] Computer use has been linked to several types of injuries known as upper extremity repetitive stress injuries, cumulative injury disorders, or work-related musculoskeletal disorders. These disorders may be associated with the upper extremities (arms, forearms, wrists, hands, and fingers) as well as the neck, back, and lower extremities. Common cumulative injury disorders associated with computer input devices include carpal tunnel syndrome, tendonitis and tenosynovitis affecting the hand, wrist, and forearm, as well as neck tension s...
