Abstract:
Apparatus for both supporting an occupant as a task chair and exercising the lumbar extensors. The chair has two configurations. One configuration is as a task chair. A second configuration is as an exercise device in which the arm rests move to restrain the anterior pelvic region and the lumbar support becomes a posterior pelvic restraint. The seatback moves through a range of motion with a strength curve ratio of about 1.4:1 between flexion and extension. The chair has a resistance mechanism that includes a four-bar linkage connected to a selectable group of coil springs. The chair includes a range of motion monitor and detectors that communicate with a feedback system, which indicates if the occupant is performing the exercise correctly. The feedback system displays a screen showing the angular position of the seatback with a comparison of the ideal position for the exercise.
