1. A foldable chair frame comprising:
two spaced leg units, two spaced backrest units, a connecting unit, and a linkage unit; wherein: each of the leg units includes a front leg, and a rear leg pivotally connected with the front leg; the backrest units are adjacent to the leg units respectively and are movable relative to the leg units to adjust a reclining angle of the backrest units relative to the leg units; the connecting unit is pivotally connected between the leg units and can be collapsed to let the leg units approach each other; the linkage unit includes at least one link module pivotally connected between the backrest units; the link module includes two links pivotally connected with the backrest units respectively; each of the links has a first pivot portion pivotally connected with one of the backrest units and a second pivot portion located opposite to the first pivot portion; the linkage unit is movable between an expanded position and a folded position; when the linkage unit is disposed at the expanded position, the link module substantially extends leftward and rightward; when the linkage unit is converted from the expanded position to the folded position, the second pivot portion of each of the links is moved upward gradually, and the first pivot portions of the links approach each other gradually; and when the linkage unit is disposed at the folded position, the link module is bent so that the leg units are moved toward each other. |
