Abstract
An inclined back support arrangement for folding furniture includes a pair of back support joints pivotally connected to two bottom ends of two back frame legs and a pair of inclination locker for pivotally coupling the two back support joints with two lower portions of the two rear side crossed legs of the seat frame respectively, so as to inclinedly support the two back frame legs in position. Moreover, by varying the coupling position of the two rear side crossed legs with the two bottom ends of the two back frame legs can adjust the inclination of the two back frame legs of the back frame.
