Abstract
A reclinable chair featuring a weight-sensitive recline mechanism is disclosed. The reclinable chair can comprise a base a support frame pivotally mounted to the base, and a support surface mounted to the support frame. The support frame can include a seat frame portion disposed between and pivotally connected to both a front frame portion and a back frame portion. The back frame portion of the support frame can also be pivotally attached to a rear end of the base, while the front frame portion can also be pivotally attached to a front end of the base. In this arrangement, the support frame and the base can cooperatively function as a linkage system capable of providing a weight-sensitive recline mechanism in a low-profile, stackable chair. The reclinable chair of the present invention can also feature a support surface featuring a pattern of openings shaped by a plurality of higher pitch curvilinear segments to provide greater flexibility and a pattern of openings shaped by a plurality of lower pitch, straighter segments to provide less flexibility.
