Abstract: A chair (10) with independent control of a lumbar portion of a seat back (18) and a thoracic portion (32) of the seat back, has a seat (14) connected with a base (12) and a control (16) connected with the base, generally under the seat. A first support (76), pivotally connected with the control, extends from the control to the thoracic portion (32) of the seat back. The two supports operate independently and the thoracic and lumbar portions of the seat back rotate independently rearward with respect to the seat (14), providing sympathetic back support for a user. The thoracic portion may rotate laterally to follow twisting movements of a user's thoracic region. The lumbar portion may be connected with the second support to limit lateral rotation of the lumbar portion.

Abstract translation: 具有独立控制座椅靠背（18）的腰部和座椅靠背的胸部（32）的椅子（10）具有与基座（12）和控制器（16）连接的座椅（14） 与基座相连，一般在座下。 与控制器枢转地连接的第一支撑件（76）从控制件延伸到座椅靠背的胸部部分（32）。 两个支撑件独立地操作，并且座椅靠背的胸部和腰部相对于座椅（14）独立地向后旋转，为使用者提供了同情的支撑。 胸部可以横向旋转以跟随使用者胸部区域的扭转运动。 腰部可以与第二支撑件连接以限制腰部的横向旋转。
