[Conventional technology]

2. Description of the Related Art In various vehicles and the like, a seat equipped in the passenger compartment is generally provided with an armrest as an armrest. For example, in a bench type seat used as a front seat or a rear back seat, a recess is provided in a part of the front side of the seat back,
Since the lower end is pivotally supported in this recess, it is always housed in the same plane as the seat back surface, and when necessary, it is tilted forward in the front of the seat to a substantially horizontal state according to the preference of the seated person. There was an armrest that was pulled out and used as an armrest.

By the way, in this type of vehicle seat 1, as shown in FIG. 4, a seat back 3 standing upright on the rear end side of the seat cushion 2 is formed by being unevenly divided in the left-right direction. It is known that the structure is. In such a seat 1, a recess 6 is provided in a left side surface portion of the seat back 5 having the larger seat width (right side in the drawing) of the left and right seat backs 4 and 5, and It has been generally practiced that the armrest 7 is pulled out by a shaft support portion (not shown) provided in the recess 6 below the recess 6 so as to be storably supported. Conventionally, as a support structure for such an armrest 7, as shown in FIG. 5, a left end that rotatably supports the armrest 7 on both sides of the base end part, a left part that is assembled by right-hand screw shafts 8 and 8, The right hinge brackets 9 and 9 are fitted with nuts 9b and 9b through holes 6a and 6a formed in the seat back 5 on the back side of the recess 6 by screw parts 9a and 9a projecting from the back side thereof.
It was known that it was fixed in. In the figure, 10 is a seat back frame that constitutes the seat back 5, 11 is a pad, 12 is a trim cover that covers the surface, and a part of this trim cover is trimmed to the frame 10 side 12a.
It is assembled and held in.

Further, as such an armrest support structure,
As shown in the drawing, a hinge member 13 fixed from the seat back frame 10 side to the side surface on the opening side of the recess 6 by welding or the like is erected and screwed to a nut member 8a embedded in the armrest 7. The L-shaped hinge bracket 14, which is rotatably supported by the screw shaft 8 and rotatably supported by the screw shaft 8, is attached to the trim cover 12 and the frame 10. Openings 15a, 15 provided
There is also known a structure in which it is guided to the back side of the seat back 5 through b and is assembled and fixed with a bolt 16 and a nut 16a.

[Problems to be solved by the device]

However, in the above-described conventional structure, the armrest 7
Hinge brackets 9, 9; 1 on the left and right sides of the
3 and 14 are rotatably supported by screw shafts 8 and 8, and these hinge brackets 9, 9 or 14 are
It is a structure in which the back side of the seat back 5 is fastened and fixed with bolts and nuts, etc., and not only the number of constituent parts increases, but also in terms of assembly workability such as reversing the seat back 5 for assembly work. This is a big problem, and a gap is formed between the side surface of the recess 11 and the pad 11 and the trim cover 12, and the hinge brackets 9 and 14 can be seen from the outside. There were also problems such as becoming.

Further, in such a conventional structure, the armrest 7 is on the left,
Screw shafts 8, 8 and hinge brackets 9, 9; 1 on both right sides
Since it is only pivotally supported by 3, 14, etc., an unreasonable force is applied from above when the armrest 7 is used, so that an excessive force is applied to the pad portion located below the armrest 7. In particular, there is a fear that bending may occur in a portion that is opened to the side of the recess 6 and a problem such as a depression may occur, and it is desired to take some measures to eliminate these problems.

[Means for Solving the Problems]

In order to meet such a demand, an armrest support structure for a seat according to the present invention is configured such that a seatback is divided in the left-right direction and a recess is formed in a side surface portion of one seatback with the other side. In a seat in which an armrest is pulled out and is axially supported so that it can be stored, a first hinge bracket provided facing a side surface opening to the other seat back side in the recess and the other side surface of the recess opposite to the first hinge bracket. A second hinge bracket embedded in the inside of the trim cover, and a hole formed in the trim cover from the side of the first hinge bracket and having a length that is hung between the two hinge brackets. It is provided with a through bolt that is screwed to the second hinge bracket side through the armrest, and the armrest is provided in the recess by the through bolt. It is obtained by rotatably supported.
