[Detailed Description of the Invention] "Industrial Application Field" The present invention provides a pull part on the trim cover that covers the cushion pad, and pulls the pull part toward the cushion pad so that the trim cover is aligned with the upper surface of the cushion pad. Regarding the trim cover mounting structure of the seat.

``Prior Art'' Conventionally, as a trim cover mounting structure for this type of seat, there are structures as shown in FIGS. 5 to 7, for example.

That is, an insert wire 2 extending horizontally is installed in a predetermined location of the cushion pad 1, and a groove 3 for retracting the trim cover is formed on the upper surface of the cushion pad 1 along the insert wire 2. There is also a working groove 4.
is provided.

The trim cover 5 that runs along the upper surface of the cushion pad 1 has its pulling part 6 inserted into the groove 3 of the cushion pad 1, and the pulling part 6 is inserted into the insert below the groove 3 using a fastening tool that enters from the working groove 4. It is fixed to the wire 2 with an ohm clip 7 and attached to the cushion pad 1.

The working groove 4 is wider than the recessed groove 3 and is deep enough to reach the insert wire 2, so that when attaching the trim cover 5 to the cushion pad 1, the fastening tool can be smoothly inserted into the working groove 4.

``Problem to be solved by the invention'' However, in such a conventional seat trim cover mounting structure, it is necessary to provide a groove 4 for inserting a fastening tool necessary for fastening the trim cover to the cushion pad. In addition, there were problems in that not only did the number of installation steps increase, resulting in high costs, but also the durability of the sheet was weakened.

A so-called hook ringer, which is a common tool for fastening, is heavy and large, making it difficult to work with, and the work of fastening the pull part 6 to the insert wire 2 with the ohm clip 7 requires skill, making the fastening work cumbersome. There were problems in that it was time consuming and costly.

Furthermore, when the cushion pad 1 is covered with the trim cover 5, the trim cover 5 is pulled and falls into the working groove 4, so the seated person can feel the fallen part and the hardness of the ohm clip 7. There was a problem in that the seating was uncomfortable.

In addition, when molding the cushion pad 1, the insert wire 2 is inserted in a substantially horizontal direction.
Since it is necessary to take into consideration the working grooves 4 and the like, there is a problem in that the three-dimensional shape of the cushion pad 1 and the like is limited.

The present invention was developed by focusing on these conventional problems, and eliminates the need for a working groove, reducing costs, as well as improving seating comfort and durability. Another object of the present invention is to provide a trim cover mounting structure for a seat that can give a free three-dimensional effect.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is to provide a pull part on the trim cover that covers the cushion pad, pull the pull part towards the cushion pad, and then remove the trim cover from the cushion pad. In the seat trim cover mounting structure along the upper surface of the cushion pad, a retracting member is attached to the retracting portion of the trim cover, and a groove into which the retracting portion of the trim cover is retracted is formed in the cushion pad. A locking member is fixed in the recessed groove, and a capsule filled with an adhesive is attached to the retracting member for adhering the retracting member to the locking member in the recessed groove of the cushion pad; Insert the retracting member of the retracting part into the recessed groove of the cushion pad so that the retractable part of the trim cover is retracted into the recessed groove of the cushion pad, and with the retracting member in contact with the locking member, the capsule breaks and adhesive is discharged. The present invention resides in a seat trim cover mounting structure characterized in that the retracting member is pressed so as to be attached to the locking member.

``Operation'' When installing the trim cover along the top surface of the cushion pad, first make sure that the pull part of the trim cover matches the concave groove of the cushion pad.
Place the trim cover along the top of the cushion pad.

Next, with the trim cover drawn to the cushion pad, the retracting member attached to the pull part is inserted into the groove of the cushion pad so that the pull part of the trim cover is pulled into the groove of the cushion pad.

With the retractable member inserted into the concave groove of the cushion pad in contact with the locking member fixed in the concave groove, press the capsule so that it breaks and the adhesive is discharged, and then move the retractable member to the locking member. Paste it on.

When attaching the retracting member to the locking member, the pressing method is, for example, by pressing the retracting member etc. with a pressurizing part of a press machine, which is approximately the same shape as the width of the concave groove, and adhering it to the retracting member. The capsule can be broken and the adhesive inside the capsule can be discharged.

The key is to use a designated tool that corresponds to the width of the groove.
Insert the retracting member into the concave groove of the cushion pad.
What is necessary is to press the capsule attached to the retracting member so that it breaks and the adhesive is discharged while the capsule is in contact with the locking member fixed in the recessed groove.

As a result, there is no need to use a working groove or a fastening tool to deeply insert the fastening tool into the trim cover retraction groove, and the working groove reduces the durability of the cushion pad. Never.

As a result, there is no need to use a fixing tool such as a so-called hook ringer, or a working groove to deeply insert the fixing tool into the trim cover retraction groove. There is no decrease in durability.

Since the retractable member of the trim cover is attached to the locking member of the concave groove of the cushion pad with adhesive,
It is also no longer necessary to install an insert wire inside the cushion pad so as to extend horizontally.

When forming the cushion pad, there is no need to consider the interior of the insert wire, so the cushion pad can be formed into various three-dimensional shapes.
Accordingly, the shape of the trim cover is not limited to a two-dimensional shape, but can also be formed three-dimensionally.

In a case where the cushion pad is covered with a trim cover, when the seated person is seated, the locking member and the retracting member that are attached to each other are in the concave groove of the cushion pad, and when pushed by the seated person, the retracting member lowers together with the cushion pad. etc. will not hit the seated person and will not impair sitting comfort.
