Title: Foldable chair frame

Abstract: A foldable chair frame includes pivotally connected front and rear legs. The front leg has a tubular upper end portion which confines an axial insert hole and which is formed with a radial positioning hole. An extension rod has a lower end portion extending axially into the upper end portion of the front leg, and is provided with a resilient positioning protrusion which projects radially into the positioning hole for positioning the extension rod on the front leg. A seat frame has a rear part pivoted to the upper end portion of the extension rod, and a front part pivoted to the upper end portion of the rear leg. The positioning protrusion is depressible for disengaging from the positioning hole to permit retraction of the extension rod into the front leg, thereby permitting folding of the front and rear legs toward the seat frame.
