As shown in FIGS. 2 and 3, two cylindrical bosses 14, 14 which are separated from each other to the left and right are provided on the back side surface of the upper member 11 at a position above the bent piece 13 to the side of the lower side. It is formed integrally. Further, mounting holes 16, 16 to the door panel side (not shown) are formed in the bent piece 15 downward on the upper side. Further, on the back side surface of the upper member 11, a convex portion 17 which is parallel to the upper side is formed.

The shock-absorbing material 31 as a cushioning material is for absorbing a shock to a shoulder portion of an occupant, and is, for example, a block-shaped molded article made of urethane foam. As shown in FIGS. 2 and 4, the shock absorbing member 31 is formed with concave portions 32, 32 that open downward on the left and right sides of the lower side, and is located in each of the concave portions 32, Are formed. This through hole 3
3 and 33 are cylindrical bosses 14 and 14 of the upper member 11.
And the cylindrical bosses 14, 14 are suitable. Note that the cylindrical boss 1 is inserted into the through hole 33.
In a state in which 4 is inserted, the convex portion 17 comes into contact with the upper surface of the shock absorber 31.

As shown in FIGS. 2 and 5, a rising piece 26 is formed on the upper side of the lower member 21 via a bent piece 25 on the back side.
Left and right step portions 27, 27 bulging out of the rising pieces 26 above the top 5 are formed. The left and right steps 27,
Mounting pieces 28 are formed by 27, and mounting holes 29 are formed in the mounting pieces 28. Here, the bent piece 1 of the upper member 11 is placed on the bent piece 25.
3 are overlapped, and the rising piece 26 overlaps the shock absorbing material 31. And the steps 27, 27
The same pitch as the recesses 32, 32 of the shock absorbing material 31,
It is adapted to each of the recesses 32, 32. The mounting holes 29, 29 have the same pitch as the cylindrical bosses 14, 14 of the upper member 11.

Next, how to attach the upper member 11, the lower member 21 and the shock absorber 31 will be described. FIG. 6 shows how to assemble the shock absorber. First, as shown in FIG. 6A, the shock absorbing material 31 is assembled to the back side surface of the upper member 11. That is, the cylindrical boss 1 of the upper member 11
4 and 14 are respectively inserted into the through holes 33 and 33 of the shock absorbing material 31, and the projection 17 of the upper member 11 is brought into contact with the upper surface of the shock absorbing material 31, so that the upper member 11 is attached to the shock absorbing material 31. Is temporarily assembled.

Subsequently, as shown in FIG. 6B, the upper side of the lower member 21 is overlapped on the lower side of the upper member 11 from the back side and screwed. That is, the recess 3 of the shock absorbing material 31 temporarily assembled on the back surface of the upper member 11 is provided.
Steps 27, 27 of the lower member 21
(Mounting pieces 28, 28) are inserted. At this time, the bent piece 25 of the lower member 21 overlaps below the bent piece 13 of the upper member 11, and at the same time, the rising piece 26 of the lower member 21 overlaps on the shock absorber 31.

Then, the mounting holes 29,
Set screw 4 with tapping screw from each of 29
1 and 41 are inserted and fastened inside the cylindrical bosses 14 and 14, respectively. In this manner, the upper side of the lower member 21 is overlapped with the lower side of the upper member 11 on which the shock absorbing material 31 has been temporarily assembled, and the lower member 21 is attached to the upper member 11 as shown in FIG. Assemble.

As described above, the vertically divided door lining 10 composed of the upper member 11 and the lower member 21 is provided.
In particular, after the cylindrical boss 14 of the upper member 11 is inserted into the through hole 33 of the shock absorbing material 31 and the shock absorbing material 31 is temporarily assembled to the upper member 11,
4 and the mounting piece 28 of the lower member 21
9 is a mounting structure in which a set screw 41 is screwed into the cylindrical boss 14. In this way, at the same time assembling the door lining 10, the shock absorbing material 31 can also be sandwiched between the lower member 21 and attached to the upper member 11, so that the number of assembling steps can be reduced.

In addition, since the conventional hot melt is not required, it is environmentally friendly. And since the shock absorber 31 can be easily separated from the upper member 11,
It is also excellent in terms of recycling.

In the above embodiment, the door lining is of a vertical split type. However, the present invention is not limited to this, and other vehicle linings such as side lining, roof lining, pillar garnish, etc. Interior parts may be used. In addition, the shapes and materials of the vehicle interior parts and the cushioning material are also arbitrary, and it goes without saying that specific detailed structures and the like can be appropriately changed.
