ABSTRACT:
A foldable chair frame includes a seat frame formed with an elongated groove which extends from a front end portion to a rear end portion of the seat frame, a first leg frame pivoted to the seat frame, and a second leg frame pivoted to the first leg frame and formed with a slide member that extends slidably into the elongated groove. When in an unfolded state, the slide member extends along the elongated groove to the front end portion of the seat frame. When in a folded state, the slide member extends along the elongated groove to the rear end portion of the seat frame. A locking unit includes a stop member disposed below the seat frame and mounted pivotally to the front end portion of the seat frame about a horizontal pivot axis. The stop member is formed with an upwardly extending stop protrusion. A biasing member biases the stop member to move the stop protrusion upwardly adjacent to the elongated groove to arrest rearward movement of the slide member along the elongated groove when the chair frame is in the unfolded state, thereby preventing untimely folding of the chair frame.
