The tension control is cam-operated to permit adjustment throughout the entire range of adjustability with only limited rotational movement of a control knob. The chair includes a recline limit control that adjusts the limit of rearward movement in the recliner mechanism. The limit control includes a cable operated stop that interact with a stepped trackway on the seat. The chair further includes a height control for adjusting the seat height including a push-button located in the tension control knob. The armrests include height and angle adjustment mechanisms. The lumbar support includes a lumbar cam that is rotatably mounted to a lumbar pad.Type: GrantFiled: September 9, 2003Date of Patent: April 18, 2006Assignee: JSJ Seating Company Texas, L.P.Inventors: Ronnie K.
