Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for processing openings in a sheet.

[Prior art] In recent years, as a vehicle seat,
As exemplified in Japanese Patent No. 155238, electric seats that can electrically move the seat back and forth and change the reclining angle have come into widespread use.

In such an electric seat, a control lever 103 is arranged on the side of the seat bag 101 (or the side of the seat cushion 102) as shown in FIG. 3, and by operating this lever, various parts of the seat are controlled. The provided motor is operated to move the seat 100 back and forth, adjust the reclining angle, etc.

In this case, in order to attach the lever 103, an opening 1 is usually formed on the side of the seat cushion 101.
104 to cause the lever 103 to protrude from the inside of the seat to the outside of the seat.

FIG. 4 shows an example of the processing structure of such an opening 104.

The opening 104 shown in this figure is the trim cover 1
08 on frame 105, frame 10.
The slits 107 formed in the trim cover 108 are overlapped and aligned with the through holes 106 of No. 5, and a cylindrical resin cover 110 having a flange 109 is inserted from the trim cover 108 side and fixed. has been done.

The cover 110 has a hook 111 formed at the lower end of its side surface, and has a through hole 106 in the frame 105.
When the hook 111 is pushed into the through hole 10
At the same time as it passes through the frame 105 while reducing its diameter, it is restored and locked to the edge of the through hole of the frame 105 to be fixed so that it does not come off.

[Problem to be solved by the invention] By the way, in such an opening processing structure,
The portion around the slit 107 in the trim cover 108 is sandwiched between the frame 105 and the flange 109, and its holding force is the same as that of the hook 111.
It is proportional to the fixing strength of the cover 110 fixed via the cover 110. Therefore, when the trim cover 108 is pulled in the direction of the arrow as shown in FIG. 5, the edge portion 108a of the slit 107 is exposed from the inside of the flange 109, spoiling the appearance and reducing the product value as a sheet. I had a problem with it.

In view of the above circumstances, the present invention can prevent the slit edges from being exposed even when the trim cover is pulled, thereby maintaining the appearance at the shipping stage and preventing the product value from decreasing. It is an object of the present invention to provide a structure for treating openings in a sheet that can prevent the above.

[Means for Solving the Problem] In order to achieve the above object, the present invention overlaps a trim cover having a slit on a flat plate frame in which a through hole is formed, and the position of the slit is aligned with the through hole. After adjusting the position of the trim cover, using a cylindrical cover having a flange at the upper end and a hook at the lower end, insert the cover into the slit and through hole from the hook side, so that the cover can be inserted through the hook. In an opening processing structure in a sheet fixed to a frame to form an opening bordered by a flange of a cover, the frame is provided around a through hole in the frame and around a slit in the trim cover;
A plurality of pin insertion holes are formed through the trim cover, and pins are integrally formed to protrude from the lower surface of the flange of the cover corresponding to the pin insertion holes, and the cover is inserted into the slit and the through hole from the hook side. At this time, the pin is inserted into the pin insertion hole, and the periphery of the slit of the trim cover is skewered and locked around the through hole of the frame.

[Function] With the above configuration, the area around the slit of the trim cover is fixed to the frame by the pin in a skewered state, so even when the trim cover is pulled, the area around the slit does not move. This prevents the slit edge from being exposed from the flange of the cover.

[Embodiment] FIG. 1 is an exploded perspective view showing an embodiment of a treatment structure for openings in a sheet according to the present invention.

The opening of the seat shown in this figure is provided on the side of the seat bag (not shown), and is composed of a frame 1, a trim cover 2 that covers the frame 1, and a resin cover 3. has been done.

The frame 1 is formed into a plate shape as shown in FIG. 2, and has elongated holes 5 in required parts for inserting operating levers, etc., and a plurality of pin insertion holes 6 around the elongated holes 5. is formed.

The trim cover 2 has a slit 7 and a plurality of holes 8 in advance at positions corresponding to the elongated hole 5 and the pin insertion hole 6.
is formed, and after it is covered with the frame 1, the position of the slit 7 and the position of the elongated hole 5 are aligned, and the position of each hole 8 and each pin insertion hole 6 is aligned. The position is adjusted by moving the trim cover 2.

The resin cover 3 includes a cylindrical portion 10 sized to fit into the elongated hole 5 in accordance with the shape thereof, and is formed integrally with the cylindrical portion 10 around the upper end of the cylindrical portion 10. Cap-shaped flange 11 and flange 11
Two pins 12 are formed integrally with the flange 11 on the lower surface side of the tube, and hooks 13 are formed integrally with both side walls at the lower end of the cylindrical portion.

Then, this cover 3 is pushed into the slit 7 and the long hole 5 from the hook 13 side, so that the hook 13 is inserted into the long hole 15 while reducing its diameter.
When it passes by, it returns to its original state and locks onto the edge of the elongated hole in the frame 1 to prevent it from coming off.

At the same time, each pin 12 is inserted into the pin insertion hole 8 through the corresponding hole 8, so that the periphery of the slit of the trim cover 2 is skewered and locked around the elongated hole of the frame 1.

In this embodiment, the two pins 12 lock the slit of the trim cover 2 around the elongated hole of the frame 1 in a skewered manner, so that the trim cover 1 is not pulled strongly. Even if the slit portion of the trim cover 1 is exposed, the slit portion of the trim cover 1 can be prevented from being exposed. Furthermore, the cover 3 can be attached by simply pushing or inserting the cover 3 in the same way as in the conventional case.

Further, in this embodiment, since the pin 12 is integrally formed on the flange 11 of the cover 3, the number of parts does not increase due to the addition of the pin 12.

[Effect of the invention] As explained above, according to the opening processing structure of the seat according to the invention, the periphery of the slit of the trim cover is fixed to the frame by the pin in a skewered state, so that the trim cover is not pulled. Even when the slit is moved, the area around the slit does not move, and it is possible to reliably prevent the slit edge from being exposed from the flange, thereby eliminating deterioration in the appearance of the product. In addition, in the processing structure of the present invention, since the pin is integrally formed with the flange of the cover, the number of parts does not increase, and the work of attaching the cover itself can be performed in the same manner as in the conventional method.
