1. A multi-joint hinge (1) for a refrigerator, comprising a mounting element (2) configured to be fixed to an appliance body and a hinge part (3) which is configured to be fixed to a door and is held pivotably on the mounting element (2) between a closed position and a maximum open position via a joint mechanism having a plurality of joint levers (4, 5, 6, 7), wherein the hinge part (3) is biased in a closing direction in a contraction range via a spring (10) and at least one linear damper (30) with a damper housing (31) and a piston rod (32) displaceable relative to the damper housing (31) is provided, which brake a closing movement of the hinge part (3) before the closing position is reached, wherein the at least one linear damper (30) is arranged with the damper housing (31) in a rotationally fixed manner via a holding element (33) within a first one of the levers of the joint mechanism, wherein the holding element (33) is fixed to the first lever (4) of the joint mechanism, wherein and the piston rod (32) is configured to be pushed into the damper housing (31) via an actuating element (14) that pushes the piston rod (32), the actuating element (14) being arranged on a further lever (7) of the joint mechanism,
wherein in the closed position, the levers (4, 5, 6, 7) of the joint mechanism are nested inside each other and the multi-joint hinge (1) is box-shaped.
