Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an ornament mounting structure for a seat of an automobile or the like.

<Prior Art> As shown in FIG. 3, an ornament 2 is attached to the front of the backrest of an automobile seat as a decoration.

As shown in FIG. 4, the attachment structure of this ornament 2 is as follows: A leg shaft 6 protruding from the ornament 2 is passed through the skin 3, cover pad 4, and main pad 5, and a retainer 7 is engaged with the tip of the leg shaft 6. It has a fixed structure. (No. 5 of Utility Model Application Publication No. 166800/1983)
(See figure) Also, the length of the ornament that penetrates the epidermis is 2.
An intermediate retainer having a small leg shaft and a large leg shaft long enough to pass through the pad is interposed between the skin and the pad, and the large leg shaft of the intermediate retainer is attached to the retainer in contact with the outer surface of the pad. There is also a structure in which the two small leg shafts of the ornament are locked to this intermediate retainer. (Refer to Figure 1 of Japanese Utility Model Application No. 62-166800) <Problem to be solved by the invention> In the former case of the above conventional structure, when the tip of the leg shaft 6 is locked to the retainer 7, the ornament 2 is Since the cover pad 4 and the main pad 5 are compressed by the ornament 2 in order to be retracted, large depressions 8 and wrinkles are formed around the ornament 2, making the front surface of the backrest 1 unsightly.

In addition, in the latter case of the above conventional structure, it is necessary to provide a leg shaft on the intermediate retainer as well, and during assembly, there is a step of locking the large leg shaft of the intermediate retainer to the retainer, and a step of attaching the small leg shaft of the ornament to this intermediate retainer. Two steps are required, including the locking step.

Furthermore, the tensile force of the ornament is transmitted to the intermediate retainer via the two small leg shafts, and the tensile force transmitted to the intermediate retainer is concentrated on one large leg shaft and locks the large leg shaft. is transmitted to the retainer. Therefore, a large concentrated force is applied to the retainer, compressing the pad around the retainer, forming dents and wrinkles, and making the rear surface of the backrest look unsightly.

Further, the area of the intermediate retainer is smaller than the area of the ornament. This creates gaps around the edges of the ornament due to repeated getting on and off.
There is a problem where the product loses its shape.

<Means for Solving the Problems> The present invention solves the above-mentioned conventional problems, and consists of a backrest consisting of an outer skin to which a cover pad is adhered to the back surface, and a main pad that is in contact with the cover pad. In a sheet ornament to be fixed to a surface, a large leg shaft long enough to penetrate the skin, the cover pad, and the main pad, and small leg shafts long enough to penetrate the skin and cover pad at two positions on the left and right with this major shaft as the center. The ornament has a stepped surface around it, and a recessed surface is formed on the inside of the stepped surface, the area of which is slightly larger than the outer shape of the ornament, and the through hole of the large leg shaft of the ornament. an intermediate retainer having a locking hole for a small leg shaft and interposed between the cover pad and the main pad with a stepped surface and a recessed surface facing the cover pad side; It consists of a retainer that locks the shaft.

<Function> With the above configuration, the large leg shaft protruding from the ornament is engaged with the retainer and the two small leg shafts are simultaneously engaged with the intermediate retainer, thereby making it possible to assemble the ornament in one step.

In addition, the tensile force of the ornament is transmitted to the retainer by the large leg shaft and to the intermediate retainer by the small leg shaft, so that no large concentrated force is applied to the retainer, and the main pads around the retainer are Prevents extreme compression and improves the appearance of the backrest.

Furthermore, the stepped recessed surface of the intermediate retainer restrains the compressive and expansive deformation of the cover pad, preventing the compressive deformation from spreading to the main pad, and the ornament is embedded in the stepped recessed surface of the intermediate retainer at a certain depth relative to the general surface of the skin.
The skin and cover pad on the periphery of the ornament are sandwiched between the periphery of the ornament and the stepped surface of the intermediate retainer, thereby preventing the occurrence of gaps and deformation of the periphery of the ornament.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In FIG. 1, 2 is an ornament, 3 is a skin, 4 is a cover pad adhered to the back surface of the skin 2, and 5 is a main pad.

The ornament 2 includes a large leg shaft 6 having a length that passes through the outer skin 3, cover pad 4, and main pad 5, and long leg shafts that penetrate the outer skin 3 and cover pad 4 at two positions on the left and right with the large leg shaft 6 in the center. A small leg shaft 6a is provided in a protruding manner.

9 is an intermediate retainer interposed between the cover pad 4 and the main pad 5. This intermediate retainer 9 has a recessed surface 11 having an area slightly larger than the outer shape of the ornament 2, and a stepped surface 10 around the recessed surface 11. A through hole 12 and a locking hole 13 for locking the small leg shaft 6a are provided.

Reference numeral 7 denotes a retainer that is brought into contact with the outer surface of the main pad 5, that is, the rear surface of the backrest, and to which the large leg shaft 6 is locked.

Since the present invention has the structure as described above, by pushing the ornament 2 into the general surface of the outer skin 3, the large leg shaft 6 protruding from the ornament 2 can be inserted into the through hole 1 of the outer skin 3, the cover pad 4, and the intermediate retainer 9.
2 and the main pad 5 to the retainer, and the two small leg shafts 6a pass through the skin 3 and the cover pad 4.
The ornaments 2 can be assembled to the backrest 1 in a single step by penetrating through and simultaneously engaging with the engagement holes 13 of the intermediate retainer 9.

After the ornament 2 is assembled, the compression/expansion deformation of the cover pad 4 is received by the stepped surface 10 and recessed surface 11 of the intermediate retainer 9.
The compressive deformation of the main pad 5 is prevented from spreading, and the ornament 2 is embedded in the general surface of the skin at a constant depth of the concave surface 11 of the intermediate retainer 9, and the skin 3 and cover pad 4 at the periphery of the ornament 2 are It is held between the peripheral edge and the stepped surface 10 of the intermediate retainer 9 to prevent gaps and deformation of the peripheral edge of the ornament 2 from occurring.

Furthermore, the tensile force of the ornament 2 is transmitted to the retainer 7 by the large leg shaft 6 and to the intermediate retainer 9 by the small leg shaft 6a in a distributed manner, so that no large concentrated force is applied to the retainer 7. , prevents the main pad around the retainer 7 from being extremely compressed, and improves the appearance of the rear surface of the backrest.

<Effects of the invention> As described above, according to the invention, the ornament has a large leg shaft long enough to pass through the outer skin, cover pad, and main pad, and the outer skin and cover pads are placed at two positions on the left and right with this large leg shaft in the center. A small leg shaft with a penetrating length is provided protrudingly provided, and a stepped surface is formed around the periphery between the cover pad and the main pad, and a recessed surface is formed inside the stepped surface, and the outer diameter of the ornament is slightly larger than that of the ornament. The ornament has a through hole for the large leg shaft and a locking hole for the small leg shaft of the ornament, and an intermediate retainer is interposed between the cover pad and the main pad with a stepped surface and a recessed surface facing the cover pad side. , the small leg shaft protruding from the ornament engages with the intermediate retainer, and the large leg shaft passes through the intermediate retainer and the main pad and engages with the retainer that abuts the main pad, so the ornament can be attached with one touch. The outer skin and cover pad on the periphery of the ornament are held between the periphery of the ornament and the stepped surface of the intermediate retainer, preventing gaps and deformation of the periphery of the ornament, and reducing the pulling force of the ornament. , stress is distributed to the retainer by the large leg shaft and to the intermediate retainer by the small leg shaft, so
To eliminate wrinkles and dents around ornaments and the retainer on the back of the backrest. Therefore, there are advantages in that the appearance of the front and back surfaces of the sheet is improved, and the mounting rigidity of the ornament is improved.
