Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for an armrest installed in a door trim.

[0002]

[Prior art]

 As shown in FIG. 8 and FIG. 9, an armrest 2 is installed in the door trim 1 installed in the door panel at a substantially central portion so that an occupant can rest his or her elbow.

The specific structure of the door trim 1 and the armrest 2 will be described. First, the door trim 1 has a skin made of a PVC sheet or the like on the surface of a core material 1a formed by pressing a composite resin plate or the like into a desired shape. The material 1b is integrally attached, and in order to give an accent to the surface texture of the door trim 1, a middle contact portion skin material 1c such as a cloth is attached to the center contact portion.

On the other hand, the armrest 2 is composed of a two-piece body including an armrest lower member 3 made of a synthetic resin injection-molded body and an armrest upper member 4 mounted on the upper surface of the armrest lower member 3. The armrest lower member 3 is fixed to the door trim 1 by screwing a screw 5a from the back side of the door trim 1 into the boss hole of the mounting boss 5 that is integrally formed on the inner surface, and is fixed to the upper surface 6 of the armless lower member 3. Has a locking hole 6a for mounting the armrest upper member 4 and a trailing edge flange 6b.

Then, by engaging the locking claw 7 integrally formed on the back surface of the armrest upper member 4 in the locking hole 6 a of the armrest lower member 3, the armrest upper member 4 is attached to the armrest lower member 3. In order to prevent the armrest upper member 4 from slipping in the direction of the arrow in FIG. 9 while being fixed to it, an insertion rib 8 is integrally formed downward along the rear edge of the armrest upper member 4. By inserting the insertion rib 8 between the rear edge flange 6b of the armrest lower member 3 and the surface of the door trim 1, the armrest upper member 4 is securely attached.

[0006]

[Problems to be solved by the device]

 However, in the conventional mounting structure of the armrest 2, when the screw 5a is screwed into the mounting boss 5 of the armrest lower member 3 from the rear side of the door trim 1, the armrest lower member 3 is excessively pulled toward the door trim 1 side. As a result, the clearance between the trailing edge flange 6b of the armrest lower member 3 and the surface of the door trim 1 becomes narrower, and this tendency is particularly noticeable when the skin material 1c of the contact portion is set.

Therefore, when the armrest upper member 4 is attached to the armrest lower member 3, the work of inserting the insertion rib 8 between the rear edge flange 6b of the armrest lower member 3 and the surface of the door trim 1 is extremely performed. It has been pointed out that there is a drawback that workability is significantly reduced.

Further, since the insertion space of the insertion rib 8 is small, when the insertion rib 8 is inserted and attached, the surface of the door trim 1 is strongly rubbed by the armrest upper member 4, and the surface of the door trim 1 is damaged, resulting in poor appearance. At the same time, the drawback of being easy to invite is pointed out.

The present invention has been made in view of such circumstances, and improves workability in mounting an armrest including an armrest lower member and an armrest upper member to a door trim, and also has a poor appearance of the door trim. The purpose of the present invention is to provide an armrest mounting structure that does not induce

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises an armrest lower member fixed with a screw at approximately the center of the door trim, and an armrest upper member mounted on the upper surface of the armrest lower member, and at the same time, the door trim table. In the armrest mounting structure, the rib for insertion formed by projecting downward along the rear edge of the armrest upper member is inserted between the surface and the rear edge flange of the armrest lower member. A contact rib is integrally formed on the back surface of the trailing edge flange, and the insertion space for the insertion rib is secured by the tip of the contact rib contacting the door trim surface.

Further, the present invention is characterized in that the inserting rib is integrally formed with the contact rib provided on the armrest lower member, and the inserting hole for inserting and fixing the inserting rib is opened in the door trim.

[0012]

[Action]

 As is clear from the above configuration, the contact ribs of a predetermined size are integrally formed on the rear surface of the trailing edge flange formed on the upper surface of the armrest lower member, and when the armless trowel member is fixed to the door trim with screws, the contact ribs are fixed. The tip abuts the surface of the door trim, ensuring a constant insertion space between the trailing edge flange and the surface of the door trim, making the insertion of the arm rest upper member insertion ribs into this insertion space much easier. It will be easier.

Furthermore, when the armrest upper member is attached to the armrest lower member, since the insertion space for receiving the rib for inserting the armrest upper member is sufficiently secured, the door trim surface is stronger than the rear edge of the armrest upper member. It is not rubbed by.
