Chair structure

Abstract

An improved chair structure for a folding chair includes a front foot support, a rear foot support, a seat frame, a back frame and an armrest. The front foot support has a top end pivotally engaged with the armrest at an inner side of a front section thereof, and pivotally engages with a front section of the seat frame between an upper and middle section thereof. The rear foot support has a top end pivotally engaged with the armrest at the outer side between a middle and rear section thereof, and pivotally engages with a pivot lever between an upper and middle section thereof. The pivot lever has one end pivotally engaged with one lateral side of the back frame at the bottom end thereof. Another side of the bottom end of the back frame is pivotally engaged with a rear section of the seat frame. The rear end of the armrest further pivotally engages with the back frame between a middle and lower section thereof. When the chair is folded, the front foot support and rear foot support may be folded in a juxtaposed manner to contact the bottom side of the armrest, and the back frame and seat frame may be folded and held in an area bordered by the front foot support. The combined folded thickness of the back frame and seat frame is substantially equal the combined folded thickness of the front foot support and rear foot support nesting under the bottom side of the armrest thereby to enable the chair to form a minimum thickness to facilitate storing and save storage space .
