Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings shown in FIGS.
[0011]
1 is an exploded perspective view showing the inside of a door of an automobile, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG.
[0012]
In FIG. 1, reference numeral 1 denotes an automobile door, 2 denotes a door trim attached to the inside of the door 1, and 3 denotes an armrest main body attached to the indoor side surface of the door trim 2.
[0013]
As shown in FIG. 2, the door trim 2 has a hard board 2a formed to be approximately the same size as the inner surface of the door 1, and substantially the entire surface excluding the mounting portion of the armrest body 3 is foamed of urethane or the like. It is covered with a skin material 2c such as vinyl chloride through the layer 2b.
[0014]
The armrest body 3 is composed of an upper armrest 4 and a lower armrest 5 formed of polypropylene (PP) resin or the like, and the upper armrest 4 is formed with a recessed portion 4a on a part of the upper surface. A pull handle portion 4b is formed for placing a hand when opening and closing the door 1.
[0015]
The lower armrest 5 has an opening 5a on its upper surface, and the upper armrest 4 is locked by locking means 6 such as an iron clip so as to cover the opening 5a. On the inner side, a hollow bracket 5 b is formed integrally with the lower armrest 5.
[0016]
As shown in FIG. 2, the bracket 5b has a substantially chevron cross section, and when the lower armrest 5 is attached to the door trim 2, a flat locking surface 5c is formed on the surface of the door trim 2 facing the hard board 2a. The rib-shaped locking portion 4c protruding from the bottom surface of the recessed portion 4a of the upper armrest 4 is locked to the locking surface 5c.
[0017]
Further, a cylindrical mounting portion 5d is provided on the locking surface 5c, and one or more similar mounting portions 5e are provided on the inner lower portion of the lower armrest 5, and are fixedly inserted from the door trim 2 side. The upper and lower portions of the lower armrest 5 are fixed to the door trim 2 by screwing the tool 7 into the mounting portions 5d and 5e.
[0018]
Next, the operation of the door armrest mounting structure constructed as described above will be described.
[0019]
When attaching the armrest body 3 to the inside of the door 1, first, the lower armrest 5 is brought into contact with the armrest mounting portion of the door trim 2 as shown in FIG. 2, and the fixing tool 7 inserted from the door trim 2 side is attached to the lower armrest 5. The lower armrest 5 is fixed to the hard board 2a of the door trim 2 by screwing it into the bracket 5b and the mounting portions 5d and 5e projecting from the lower portion.
[0020]
Next, in this state, the upper armrest 4 is fitted into the upper surface opening 5a of the lower armrest 5 from above, and the locking means 6 provided on the upper armrest 4 is locked to the opening 5a of the lower armrest 5. Thus, the upper armrest 4 is attached to the lower armrest 5. At this time, a rib-like locking portion 4 c protruding from the bottom surface of the recessed portion 4 a of the upper armrest 4 is engaged with the bracket 5 b provided on the lower armrest 5. As shown in FIG. 2, the retaining surface 5c is locked from the hard board 2a side.
[0021]
When the armrest body 3 is attached to the door trim 2 as described above, the door arm 2 is attached to the interior side of the door 1 by attaching the door trim 2 to the inside of the door 1, and the upper armrest 4 is attached to the lower armrest 5. Since the work of inserting the fixing tool and the tool from the recessed portion 4a of the upper armrest 4 is not required, the upper armrest 4 can be easily attached in a short time, and there is no fear of accidentally damaging the door trim 2 with the tool.
[0022]

[0023]
However, the front end of the bracket 5b of the lower armrest 5 and the lower mounting portion 5e of the lower armrest 5 are fixed to the hard board 2a of the door trim 2 by the fixing tool 7 and protruded from the bottom surface of the recessed portion 4a of the upper armrest 4. Since the stopper 4c is locked to the locking surface 5c of the bracket 5b, even if the upper arm rest 4 is deformed as indicated by the phantom line in FIG. In addition, since there is no gap between the other part and the door trim 2, there is a concern that the appearance may be lost, or that foreign matter may enter the armrest body 3 from the gap and cause noise during driving. Absent.
[0024]
【The invention's effect】
As described in detail above, the present invention attaches the bracket provided at the upper portion of the lower armrest and the attachment portion provided at the lower portion to the door trim, and the locking portion protruding from the bottom surface of the recessed portion of the upper armrest. Since the upper armrest is attached to the lower armrest by the locking means in the locked state, when pulling on the pull handle part of the upper armrest to open and close the door, a pulling force acts on the pull handle part. Even if the upper armrest is elastically deformed by this tensile force, the upper bracket and lower mounting portion of the lower armrest are attached to the door trim, and the locking portion protruding from the bottom surface of the recessed portion of the upper armrest is engaged with the bracket. Since it is stopped, there is no gap between the upper armrest and the door trim.
[0025]
As a result, the appearance of the interior material is not deteriorated, and foreign matter or the like does not enter the armrest body through the gap, so that there is no fear of generating abnormal noise while the automobile is running.
[0026]
In addition, since it is not necessary to insert the fixing tool and tool from the recessed part of the upper armrest and attach the upper armrest to the lower armrest, the number of man-hours required for assembly work can be reduced, and the door trim can be damaged by the tool. Can also be resolved.
