BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an exploded perspective view illustrating an armrest mounting structure with a cover plate, FIG. 2 is a perspective view showing a state in which an armrest is mounted on an automobile rear seat, and FIG. 3 is a sectional view of the mounting structure. As shown in FIG. 1, the rear seat back 2 of the rear seat 1 is formed with an armrest storage space 4 having a substantially U-shaped flat cross-section with a front open at the center in the width direction.

In the rear seat back 2, a hinge bracket 5 made of a rigid material made of an iron plate or a steel plate, which is substantially U-shaped in plan view as shown in FIG. 4, is insert-molded so as to surround the lower portion of the armrest storage space 4. It The hinge bracket 5 is insert-molded in a state where the hinge bracket 5 is joined to a wire constituting the rear seat back frame 2a as shown in FIG. 7 by welding. Although the drawing shows the case where the rear surface of the hinge bracket 5 is welded to the wire extending in the vertical direction, it may be welded to the wire extending in the horizontal direction or may be welded to the front surface of the hinge bracket 5. .

As shown in FIG. 1, a pair of left and right hinge portions 5a facing each other of the hinge bracket 5 are exposed on the left and right inner side surfaces of the armrest storage space portion 4, and the hinge portion 5a has a structure shown in FIG. As shown in FIG. 5, a circular mounting hole 6 is provided, and a leaf spring 7 as an elastic member is joined to the inner surface of the hinge portion 5a adjacent to the mounting hole 6 by welding.

A cover plate 8 for covering the bottom surface of the armrest storage space 4 and the hinge portion 5a of the hinge bracket 5 is arranged. As shown in FIG. 1, the cover plate 8 is formed in a vertically long rectangle and is made of a synthetic resin capable of elastic bending. Also,
On the lower side of the cover plate 8, a pair of left and right hinge cover portions 8a with a collar that covers the hinge portion 5a of the hinge bracket 5 are provided so as to project forward.
A cylindrical pin 9 having a cylindrical shape that can be fitted into the mounting hole 6 of the hinge portion 5a is formed in a.

The armrest 10 which is composed of a vertically long rectangular parallelepiped mainly composed of a cushion material is provided with circular mounting pins 11 which can be fitted into the cylindrical holes of the cylindrical pin 9 of the hinge cover portion 8a at the lower left and right side surfaces thereof. This mounting pin 11
Is welded to an insert hardware (not shown) provided in the armrest 10.

FIG. 6 is an explanatory view showing a mounting mode of the cover plate 8 and the armrest 10. As shown in FIG. 6A, first, the cover plate 8 is attached to the hinge bracket 5. That is, the elastic deflection of the cover plate 8 is used to reduce the distance between the left and right hinge cover portions 8a as shown by the solid line in the figure, and then the hinge cover portions 8a are inserted between the hinge portions 5a of the hinge bracket 5 to form a cylindrical pin The cover plate 8 is attached to the hinge bracket 5 by fitting 9 into the attachment hole 6.

The hinge cover portion 8a of the cover plate 8 attached in this manner covers the outer periphery of the hinge portion 5a by the flange portion projecting outwardly.
Further, the leaf spring 7 presses the outer surface of the hinge cover portion 8a, and the hinge cover portion 8a and the hinge portion 5a
A gap C is formed between the surfaces facing each other when the armrest 10 is attached and that allows the hinge cover 8a to elastically bend in the expanding direction.

Therefore, when mounting the armrest 10, as shown in FIG. 6B, the left and right hinge cover portions 8a of the cover plate 8 are spread outward by utilizing elastic bending. At that time, since the leaf spring 7 is also elastically deformed, the lower side of the armrest 10 is hinged to the hinge cover portion 8 in that state.
The armrest 10 is attached to the cover plate 8 by inserting it between a and inserting the attachment pins 11 on both sides into the tubular holes of the tubular pin 9 of the hinge cover portion 8a. The state of attachment in this way is shown in FIG.

Thus, the cover plate 8 and the armrest 10 are attached to the armrest storage space 4 of the rear seat back 2. When not in use, the armrest 10 is stored in the armrest storage space 4 as shown in FIG. 2 (A) by flipping up the mounting pin 11 rearward, and when it is in use, it is pulled forward. As shown in FIG. 2B, the rear seat cushion 3 is laid down for use.

According to the above-described present embodiment, the hinge bracket 5 is provided on the rear seat back 2 side, and the cover plate 8 and the armrest 10 are fitted into the pin and the hole, that is, the cylindrical pin 9 and the mounting hole 6. Since the mounting pin 11 and the cylindrical hole of the cylindrical pin 9 are fitted to each other, the mounting work to the rear seat back 2 can be easily performed, and the conventional troublesome screw tightening work can be performed. Compared with this, work efficiency is improved.

Further, according to the present embodiment, the armrest plate 23 shown in FIG. 6 and the bolts 29 and nuts 30 for fastening the hinge bracket 26 to it, which are used in the conventional mounting structure, are unnecessary, so that the armrest 10 is mounted. The number of parts related to can be reduced.

Furthermore, in the present embodiment, the armrest 10 is set by setting the gap C that allows the elastic bending of the hinge cover portion 8a of the cover plate 8 to the outside.
The leaf spring 7 is set between the hinge portion 5a and the hinge cover portion 8a so as to fill the gap C, and the gap of the cover plate 8 with respect to the hinge bracket 5 is reduced. It suppresses rattling and can be retained at the initial mounting position.

The present invention is not limited to the above-described embodiments, but may be modified as follows within the scope of the invention. The application of the armrest mounting structure of the present invention is not limited to the rear seat 1 of an automobile. Instead of using the leaf spring 7 as the elastic member for preventing the rattling of the cover plate 8, a coil spring or elastic rubber may be used. The attachment of the cover plate 8 to the hinge bracket 5 may be changed to a configuration that uses elastic bending of the cover plate 8 so that the hinge portion 5a of the hinge bracket 5 causes elastic bending.

Further, the cover plate 8 and the armrest 10 may be attached by a fitting structure with a pin and a hole, respectively, and a pin is provided on one side and a hole is provided on the other side between the attachment member and the receiving side member. You can go. Further, in the embodiment, the mounting center of the cover plate 8 and the mounting center of the armrest 10 are aligned on the same axis, but they may be set on different axes.

[0023]

As described in detail above, according to the present invention,
The fastening structure using bolts and nuts can be eliminated, the work of attaching the armrest to the seat can be easily performed, and the number of parts relating to the attachment can be reduced.
