Abstract

An arrangement of an arm rest in an automotive seat, with a collar interposed via a support rod between the arm rest and lateral wall of the seat, wherein the collar is formed to conform to the curved surface of that lateral wall of the seat, to thereby prevent creation of the clearance and thus avoid objectionable view of the support rod in the collar.

Claims

1. An arrangement for an arm rest in an automotive seat having a seat back to which said arm rest is rotatably mounted by a support rod, said seat back including a curved lateral wall having an outward curvature extending in a direction from a rear wall of said seat back to a front seating surface of said seat back, said arrangement comprising:

a collar through which said support rod passes;

a stopper means secured in said collar, said stopper being fixed on said support rod; and

a back garnish member provided rearwardly of said seat back,

wherein said collar is so formed that its one side edge has a contour conforming to said curved lateral wall of said seat back and its other side edge has a contour conforming to a wall of said arm rest which faces towards said lateral wall of said seat back, wherein said collar is further provided with a securing part which is secured between said back garnish member and said lateral wall of said seat back, wherein said collar and stopper are interposed between said arm rest and said lateral wall of said seat back, to thereby prevent said support rod from being viewed externally, and wherein said lateral wall of said seat back has an outward curvature that increases in degree from said rear wall to said front seating surface of said seat back, wherein said wall of said arm rest is formed flat, and wherein said one side edge of said collar is so formed as to have a sloped plane in conformity with said outward curvature of said lateral wall of said seat back, while said other side edge of said collar is formed flat in conformity with said flat formed wall of said arm rest.

2. The arrangement as defined in claim 1, wherein said collar is formed in a cylindrical shape, having formed therein a reinforcing rib and securing compartment in an integral manner, said securing compartment being adapted for receiving said stopper supportively, and further said collar has at its center a hole through which said support rod passes.

3. The arrangement as defined in claim 2, wherein said stopper is formed with a pair of opposed stopper pawls, and wherein said pair of opposed stopper pawls are respectively received in said pair of securing compartments.

4. The arrangement as defined in claim 1, wherein said collar is made of a synthetic resin material.
