Description

[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, for example, Utility Application No. 58-164438
The specification and drawings attached to the application No. 60-72699), as well as the application No. 58-57500 (Utility Model Application No. 59-
No. 164599), each of which is disclosed in the specification and drawings attached to the application.

That is, the former has a structure in which a pulling member provided on the surface material is attached to the frame via a band material, and the latter has a structure in which a stopper is provided on the front cover and a tensioner is provided on the back cover. and the tension body is locked to the stop body.

In the former method, the pulling member is attached to the frame via a strip, so it is easier to work with than directly attaching the pulling member to the frame. Since it is locked to the back cover through the stopper, it is easier to work with than directly locking the stopper to the back cover.

``Problem to be solved by the invention'' However, in the conventional seat trim cover mounting structure, when sewing the pull member to the strip material, for example, the strip material is moved from the back side of the cushioning material to the front surface. It is necessary to pull the pull member to the side and sew the pull member to the pulled-in strip material, which is a cumbersome sewing process. The positioning of the back cover requires precision, and it is necessary to lock the back cover in a positioned state, which also poses the problem of cumbersome work.

The present invention has been made in view of these conventional problems, and an object of the present invention is to provide a seat trim cover mounting structure that can improve workability.

"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 that extends along the upper surface of the cushion pad, an insert wire is installed inside the cushion pad by extending it forward and backward on both sides of the cushion pad, and a retractable member is connected to the insert wire, and the insert wire is installed along the insert wire. forming a groove for retracting the trim cover, and when forming the groove for retracting the trim cover, attaching the retracting member to the bottom and inner wall of the groove for retracting the trim cover; Peel the trim cover from the bottom and inner wall of the groove for pulling in the trim cover, pass the tip of the retracting member into the groove for pulling in the trim cover, and extend it to the vicinity of the opening of the groove for pulling in the trim cover. The seat trim cover mounting structure is characterized in that the leading end of the retracting member is fixed to the retracting portion of the trim cover in a state where the retracting member is pulled toward the cushion pad.

"Operation" A retracting member is attached to the bottom and inner wall of the trim cover retracting groove, and the tip of the retracting member can be trimmed by simply peeling the retracting member from the bottom and inner wall of the trim cover retracting groove. Pass it through the cover retraction groove and extend it to the vicinity of the opening of the trim cover retraction groove.

Place the trim cover over the cushion pad so that the pull part of the trim cover corresponds to the groove for retracting the trim cover.

Next, with the trim cover drawn to the cushion pad, for example, all you have to do is bring the fastening tool close to the opening of the trim cover retraction groove without deeply inserting it into the trim cover retraction groove. The tip of the member can be fixed to the pull part of the trim cover.

"Embodiments" Hereinafter, various embodiments of the present invention will be described based on the drawings. Incidentally, the same types of parts in various embodiments are given the same reference numerals and redundant explanations will be omitted.

1 to 5 show a first embodiment of the invention.

As shown in FIGS. 1 to 4, the cushion pad 10 is raised on both sides 11, and as a result is provided with a depression in the center 12 thereof.

Insert wires 20 extending in the front-rear direction are housed in both sides 11 of the cushion pad 10. Similarly, insert wires 21 and 22 are installed in the front and rear parts of the cushion pad 10, respectively.

The cushion pad 10 is formed with a trim cover retracting groove 15 having a substantially U-shaped cross section along the insert wires 20, 21, and 22. The insert wires 20, 21, 22 have a retracting member 3.
The base end portions 31 of 0 are connected.

As shown in FIG.
7, the cushion pad 10 is shaped
When the cushion pad 10 is foam-molded by D1 and D2 and taken out from the molds D1 and D2, the retracting member 30 is attached to the bottom surface 16 and inner wall 17 of the trim cover retracting groove 15.

When the retracting member 30 is peeled off from the bottom surface portion 16 and the inner wall 17, the distal end portion 32 of the retracting member 30 passes through the trim cover retracting groove 15 and extends to the vicinity of the opening 18 thereof.

A pull part 41 is formed in the trim cover 40 that covers the cushion pad 10 in correspondence with the groove 15 for retracting the trim cover in the cushion pad 10. Trim cover 40 has cushion pad 10
In this state, the pull portion 41 of the trim cover 40 is fixed by an ohm clip 51 to the distal end portion 32 of the retracting member 30, which extends to the vicinity of the opening 18 of the groove 15 for retracting the trim cover.

Next, the action will be explained.

Peel the retracting member 30 from the bottom surface 16 and inner wall 17 of the trim cover retracting groove 15 of the cushion pad 10, and
is extended to the vicinity of the opening 18 of the groove 15 for retracting the trim cover.

A trim cover 40 is placed over the cushion pad 10 so that a pull part 41 of the trim cover 40 corresponds to a groove 15 for retracting the trim cover.

Next, attach the trim cover 40 to the cushion pad 1.
0, and then roll up the outer peripheral edge of the trim cover 40. In this state, bring the tool close to the opening 18 of the trim cover retraction groove 15, and pull the pulling part 41 of the trim cover 40 to the tip of the retracting member 30. It is fixed to the portion 32 with an ohm clip 51.

After all the pulling parts 41 of the trim covers 40 are fixed to the tips 32 of the retracting members 30, the outer peripheral edges of the trim covers 40 that have been rolled up are lowered and fixed to the predetermined parts, and the trim covers 40 are attached to the cushion pads 10. It is coated along the top surface.

In the seat with the above-mentioned mounting structure, the ohm clip 51, which is pushed by the seated person and fixes the tip end 32 of the retracting member 30 and the retracting portion 41 of the trim cover 40, is located in the groove for retracting the trim cover. 15 and lowers together with the cushion pad 10, the ohm clip 51 does not hit the seated person, and the insert wire 2
Since the points 0, 21, and 22 are located at deep positions, they do not hit the seated person and do not impair sitting comfort.

FIG. 6 shows a second embodiment of the invention.

In this embodiment, a retraction piece 70 is provided at the corner portion 66 of the retraction groove 65, and the trim cover 40 is
The pulling portion 45 of the cushion pad is pulled toward the cushion pad without loosening.

7 and 8 show a third embodiment of the invention.

The one shown in FIG. 7 has a retractable member 30a made of a stretchable material, and the one shown in FIG. It is curved and molded. Thereby, the center portion of the trim cover 40 can be more reliably aligned with the recess in the center portion 12 of the cushion pad 10.

"Effect of the invention" According to the seat trim cover mounting structure according to the invention, the proximal end of the retractable member is connected to the insert wire before the cushion pad is molded, and the trim cover retracting groove is connected when the cushion pad is molded. Since the retracting member attached to the bottom part and the inner wall is peeled off and used, work efficiency can be improved.
