摘要： The present design is of a variable posture component system seating device, also called a work chair, which integrates user selectable and adjustable components. The components consist generally of a short base, a long base, height adjustment mechanisms, a seat adjustment mechanism, a seat assembly, right and left arm rest assemblies, an abdominal rest assembly, a back rest assembly, a head rest assembly, a knee/leg rest assembly, a keyboard desk assembly, an auxiliary desk assembly, a horizontal work surface assembly, and a variety of interconnecting hardware. Numerous improvements to a variable posture work chair are incorporated into the design, which can benefit workers subjected to extended periods of immobilization as well as the infirm and the injured. Fore and aft support from a single seated position is provided over the entire range of leaning normally associated with human sitting. A variety of work surfaces may be incorporated into the design, and certain of these may be mounted to the chair by using arm rests which may also be moved between positions of use and nonuse. Components may be added, removed, or displaced to accommodate specific physical and workplace needs. An elongated low profile chair base of single unit construction provides stability to the chair assembly while allowing for maximum leg and foot clearance. Suggested uses are in the home, office, and industrial work place.

摘要： A system for supporting a seat-pan on a chair and for providing movement to an armrest on the chair. The system includes a mounting assembly with an upper rail having a front portion, a mid portion and a rear portion, and a lower rail having a front portion, a mid-portion and a rear portion. The upper rail is pivotally connected to the lower rail in a manner which allows g generally parallel motion of the rails relative to one another. An armrest support is pivotally attached to the mounting assembly, and includes a linkage for indexing movements of the armrest support relative to motion of the position of the upper rail relative to lower rail, so that motion of the upper rail relative to the lower rail produces a corresponding tilt of the armrest support.
