Claim:
A retractable furniture device comprising: a seat frame having opposite front and rear frame portions; a base frame disposed under said seat frame and including opposite curved lateral rods, each of which has two front and rear end portions; and two supporting units for supporting said seat frame on said base frame, each of said supporting units including an inclined elongate first support member connected pivotally between said rear end portion of a corresponding one of said lateral rods of said base frame and said front frame portion of said seat frame, a foldable second support member having a first rod section connected pivotally to said front end portion of the corresponding one of said lateral rods of said base frame at one end, a second rod section connected pivotally to said rear frame portion of said seat frame at one end, and a third rod section having two opposite ends connected respectively and pivotally to the other end of said first rod section and the other end of said second rod and connected pivotally to an intermediate portion of said first support member, and a foldable retracting control member having a first coupling end connected pivotally to said first support member and disposed between said third rod section of said second support member and said rear end portion of the corresponding one of said lateral rods of said base frame, and a second coupling end opposite to said first coupling end and connected pivotally to a junction of said first and third rod sections of said second support member; said furniture device being operable so as to change between an expanded state, where said retracting control member of each of said supporting units is unfolded and is spaced apart from the corresponding one of said lateral rods of said base frame and where said second support member of each of said supporting units is unfolded and extends upwardly and rearwardly from said front end portion of the corresponding one of said lateral rods of said base frame, and a retracted state, where said retracting control member and said second support member of each of said supporting units are folded and are proximate to the corresponding one of said lateral rods of said base frame such that said supporting units are superposed between said base frame and said seat frame.
