Abstract

A foldable chair frame includes a seat frame, a front leg frame, a backrest frame with two lateral rods mounted pivotally to the seat frame, and an armrest frame with two armrest bars disposed adjacent to opposite lateral sides of the seat frame. Each of the armrest bars has a front section which extends forwardly of the backrest frame, and a rear section which extends downwardly from the front section and which is mounted pivotally to a rear end portion of the seat frame posterior to the backrest frame. A locking unit includes a locking seat fixed to one of the armrest bars and formed with an engaging hole, and a locking member having a ring portion sleeved rotatably and slidably on an adjacent one of the lateral rods, and a radial outward latch projection which is provided with a downwardly extending insert section. The locking member is movable on the lateral rod so as to engage the insert section within the engaging hole in order to position the chair frame in an unfolded state, and so as to disengage the insert section from the engaging hole in order to permit folding of the chair frame.
