Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trim cover terminal fastening device for a vehicle seat.

[0002]

2. Description of the Related Art In a vehicle seat conventionally provided in a vehicle such as an automobile, the surface of a pad made of a cushion material is covered with a trim cover (skin material). Further, although the end of the trim cover is fixed by a cushion frame, various fixing devices for the trim cover have been conventionally proposed.

In Japanese Utility Model Laid-Open No. 56-98068, for example, a locking piece provided on the skin side is engaged with a locking portion provided on the frame side to fix the skin to the frame.

In Japanese Utility Model Laid-Open No. 60-20898 and Japanese Utility Model Laid-Open No. 62-79500, a plate having projections and holes for engaging with each other is provided on the frame and the skin material, and these plates are interposed therebetween. A skin material is attached to the frame.

However, in these conventional fastening structures, there is a problem that the fastening portion easily comes off when the skin material expands and contracts during use.

Another fastening device shown in FIGS. 6 and 7 is also used.

In this fastening device, the cushion frame a
The cut-and-raised b is provided on the side, and the J-hook d attached to the trim cover c side is engaged with the cut-and-raised b to fix the trim cover c to the cushion frame a. Has been done.

[0008]

However, in the fastening device as described above, since the J hook d attached to the trim cover c engages with the cut and raised portion b of the cushion frame a, this portion has four layers. As a result, there is a problem that the thickness t becomes thicker and the appearance is not good.

When fixing the trim cover c along the corners R of the front and side surfaces of the seat, the trim cover c must be divided and fixed in order to improve the followability of the trim cover c. However, there is a problem that it takes time to sew the trim cover c.

The present invention has been made to solve the above-mentioned problems, and the trim cover can be fixed without being divided,
Moreover, it is an object of the present invention to provide a trim cover terminal fastening device for a vehicle seat that does not easily come off even if the trim cover expands and contracts.

[0011]

In order to achieve the above object, the present invention is directed to a vehicle seat in which the surface of a cushion installed on a cushion frame is covered with a trim cover, and a cut-and-raised portion is formed around the cushion frame. By forming a plurality of cut-and-raised parts at intervals so that the bending directions are alternated, and by inserting the engaging holes of the band-shaped fastening member fixed to the end of the trim cover into these cut-and-raised parts, The end of the trim cover is fixed to the cushion frame.

[0012]

With the above-mentioned structure, the trim cover terminal has four fastening portions.
Since it does not have a layered structure, it does not become thick, and even if the trim cover expands and contracts during use, the trim cover does not come off due to the cut-and-raised parts having different cut-and-raised directions. Further, since the trim cover terminals at the corners of the seat can be attached to the cushion frame without dividing the trim cover, the trim cover can be easily sewn.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of the trim cover terminal fastening device, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a sectional view taken along the line BB of FIG.

In these figures, reference numeral 1 denotes a cushion frame which constitutes a vehicle seat, and a cushion 4 is placed on the surface thereof, and the surface of the cushion 4 is a trim cover 2.
Is covered by. Also, the cushion frame 1
A plurality of cut-and-raised parts 1a and 1b are formed at equal intervals in the peripheral portion on the back surface side of the so as to alternate the cut-and-raised directions. The cut-and-raised portions 1a and 1b are engaged with the fastening body 3 sewn to the end of the trim cover 2.

The fastening body 3 is formed of a soft synthetic resin into a bendable band shape along the periphery of the cushion frame 1, and the cut-and-raised portion 1 formed on the cushion frame 1 is formed.
The long engaging holes 3a are opened at the same intervals as a and 1b, and the R portion of the corner of the seat is also trimmed.
The fixing body 3 is fixed without dividing.

Next, the operation will be described. When the end of the trim cover 2 that covers the cushion 4 is fixed to the cushion frame 1, the locking hole of the band-shaped fixing member 3 fixed to the end of the trim cover 2 is fixed. 3a is sequentially inserted into the cut-and-raised parts 1a and 1b in which the cut-and-raised directions are alternately reversed.

Also, as shown in FIG. 1, the corner portions of the seat are not required to divide the trim cover 2 by inserting the fastening body 3 into the cut-raised portions 1a and 1b of the cushion frame 1 without dividing the trim cover 2.
Since the trim cover 2 can be fixed by following the corners of the cushion 4, the appearance is also good.

In the above-described embodiment, the fastening hole 3a is provided in the fastening body 3 so as to be fitted into all of the cut and raised portions 1a and 1b.
Alternatively, as shown in FIG. 5, it may be provided every other one, and the portion without the engagement hole 3a may be cut and raised to pass through the lower side.

[0020]

As described in detail above, according to the present invention, a plurality of cut and raised portions are formed at intervals in the peripheral portion of the cushion frame so that the cut and raised directions are alternated, and the trim portions are trimmed. Since the engaging hole of the band-shaped fastening body fixed to the end of the cover is fitted and inserted, the end of the trim cover can be easily fastened, and since the fastening part does not have a four-layer structure, it does not become thicker. Good.

Further, since the cut-and-raised directions are alternately reversed, the trim cover does not come off even if the trim cover is expanded or contracted during use, and the engaging hole is opened in accordance with the cut-and-raised. Therefore, the trim cover does not shift.

Further, at the corners of the seat, the trim cover can be made to follow the R portion without dividing the trim cover, so that the labor required for sewing can be reduced as compared with the conventional split. The cost can be reduced.
