The present invention relates to a hair cutting appliance (10) comprising a linkage unit (30) for a cutting unit (18), and to a linkage unit (30) for coupling a cutting unit (18) and a housing (12) of a hair cutting appliance (10). The linkage unit (30) comprises a four-bar linkage mechanism (32) comprising a first arm (42) and a second arm (44), the first arm (42) comprising a first base pivot (48) coupled to a base (38), the second arm (44) comprising a second base pivot (50) coupled to a base (38), the first base pivot (48) and the second base pivot (50) being arranged at the base (38) at a fixed distance, the first arm (42) further comprising a first top pivot (52) coupled to a connecting bar (46), the second arm (44) further comprising a second top pivot (54) coupled to the connecting bar (46), wherein the connecting bar (46) is arranged to be coupled to a cutting unit (18), such that, during operation, the cutting unit (18) is pivotably supported by the linkage mechanism (32). Preferably, at least one of the first base pivot (48) and the second base pivot (50) and the first top pivot (52) and the second top pivot (54) is arranged as a living hinge. |
