发明名称 Chair back construction
摘要 A back for a chair includes fabric panel with a flexible carrier attached to the panel around its periphery. The carrier is configured to be secured along a bottom edge to a bottom portion of a chair back frame member. The carrier is also secured to two vertical frame supports at its two upper corners. Preferably, the upper carrier and frame connections are ball and socket joints. A lumbar support is provided that is easily height adjustable, by providing tension to the back frame and requires no screws or adjustment knobs in its adjustment mechanism.
