Disclosed is a hinge device for an armrest fixed in multi-stages. According to the present invention, the hinge device for an armrest fixed in multi-stages comprises: a rotor which rotates an armrest around a rotary shaft with respect to a base, is coupled to the armrest to form a rotary shaft, and has a cam protruding from an end at right angles to the rotary shaft on an end thereof; and an elastic body which is coupled to the base and has an uneven part to elastically support the cam while being in contact with the cam within a rotating range of the cam. Accordingly, the armrest is fixed in multi-stages by the cam rotating along the uneven part. According to the present invention, the multi-stage hinge device for an armrest simplifies an assembly process by having a simple configuration comprising the rotor and the elastic body, thereby reducing production hours. Moreover, the present invention facilitates disassembly and repair to improve user convenience and fixes the armrest in multi-stages by a predetermined angle as the cam is elastically supported while repeatedly going over the uneven part. |
