The present invention relates to an armrest hinge assembly of two row seat for a car. The invention includes a pair of hinge brackets to be shaped in a piece in a part of a seat and to keep some distance from each other; a hinge hole to be formed while penetrating the hinge bracket; a hinge shaft fixed to one end of an armrest frame to be inserted into the hinge hole; a trajectory pin hole to be formed near the hinge hole; a trajectory pin to be inserted and fixed into the trajectory pin hole; a trajectory hook to be formed near the one end hinge shaft of the armrest frame to provide additional supporting force when the armrest frame rotates based on the hinge shaft in case the trajectory pin is caught. The trajectory pin comprises an insertion end in which a step is formed on one end; a head to be formed in the other end; and a plurality of rotation preventing protrusions to protrude in the direction of a circumference facing the insertion end from a lower side of a head, and each trajectory pin hole is formed in the way to correspond to the insertion end and the rotation preventing protrusion. According to the invention, a hinge structure can become simple through improved armrest structure, therefore, coupling job can be performed easily and rapidly. In addition, as many additional parts are not needed, its weight can be reduced and the production costs can be also decreased. |
