DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS. In this embodiment, the present invention is applied to a seat back 2 (vehicle seat) and a seat back cover 3 (seat cover) covering the same.
However, the present invention can also be applied to the seat cushion 1 and a seat cushion cover (not shown) for covering the same.

As shown in FIG. 3, the seat back 2 includes a seat back frame 2A made of a hard resin, and a seat back cushion 2B attached to a front portion of the seat back frame 2A. The seat back frame 2A is formed by molding a resin,
On its back surface, a square annular mounting groove 22 is formed. The mounting groove 22 is arranged so as to surround the portion 21 to be used as a table.

As shown in FIGS. 1 and 4, mounting grooves 2 are provided at the open ends of both side surfaces 23, 23 of the mounting groove 22.
2, two protruding portions 24 protruding inward in the width direction are formed. The protrusion 24 extends along the mounting groove 22 with an appropriate length, and a plurality of the protrusions 24 are formed on each of four sides of the mounting groove 22 at appropriate intervals. The surface facing the bottom side of the mounting groove 22 of the outer surface of the protrusion 24 is the locking surface 25. The mounting groove 22 and the protruding portion 24 are formed at the same time when the seat back frame 2A is formed.

As shown in FIG. 3, the seat back cover 3 is made of a resin sheet, and has a box-shaped housing portion 31 for housing the seat back 2 and an open portion of the housing portion 31. It comprises an upper cover portion 32 for closing a portion corresponding to the upper end portion of the seat back 2, and cover pieces 33 respectively connected to the upper cover portion 32 and three upper sides of the housing portion. The distal end of each cover piece 33 is a terminal 34 to be fixed in the mounting groove 22 of the seat back frame 2A. After the seat back 2 is inserted into the accommodation portion 31, each cover piece 33 is moved in the direction of the arrow in FIG. When rotated and attached to the seatback frame 2A, the terminal 34 can be inserted into the mounting groove 22.
The length of each cover piece 33 (the length from the base end to the tip end of the cover piece 33) is set.

As shown in FIG. 1, the seat back cover 3
In the terminal, each cover piece 33 is attached to the seat back frame 2.
A fixing member 4 is sewn and fixed to a surface facing the seatback frame 2A when the member is attached to the seatback frame 2A.

The fixing member 4 is inserted into the mounting groove 22 so as not to escape, so that each terminal 3 of the seat back cover 3 is
4 is fixed to the seat back frame 2A, and is configured as follows. As shown in FIG.
The fixing member 4 is formed by extruding a resin and cutting it slightly shorter than the length of each side of the square mounting groove 22.
And a contact portion 43 formed at the other end of the plate portion 41.

The thickness of the plate portion 41 is smaller than the width of the mounting groove 22, and the terminal 34 of the seat back cover 3 is fixed to an intermediate portion thereof. In this case, the terminal 34 is fixed to the side surface of the side portion 2a used as a table among the both side portions of the plate portion 41. Therefore, when the fixing member 4 is inserted into the mounting groove 22 from the other end, the seat back cover 3 covers the fixing member 4. Note that the terminal 34 is fixed to the plate portion 41 by sewing, but may be fixed by another method.

The protruding pieces 42, 42 are inclined so as to move away from each other as they approach the distal end, whereby the other end of the fixing member 4 is formed in a "Y" shape. Each protruding piece portion 42 is elastically deformable so as to approach and separate from each other. In addition, one of the protruding pieces 42
The dimension from the outer surface of the distal end portion to the outer surface of the distal end portion of the other protruding piece portion 42 is equal to or slightly larger than the width of the mounting groove 22.

Therefore, when the fixing member 4 is inserted into the mounting groove 22 from the other end, the protruding pieces 42, 42 abut against the protruding parts 24, 24 and are elastically deformed so as to be narrowed. When the fixing member 4 is further inserted into the mounting groove 22 and the protruding pieces 42, 42 get over the protruding parts 24, 24, the protruding pieces 42, 42 expand so as to return to the original state, and the respective tips are mounted. It abuts against both side surfaces of the groove 22 and abuts the locking surfaces 25, 25 of the protrusions 24, 24. Thereby, the fixing member 4 cannot be removed from the mounting groove 22, and the seat back cover 3 is fixed to the seat back frame 2A. Moreover, since the protruding pieces 42 are inclined, when the fixing member 4 is to be taken out from the mounting groove 22 toward its open side (upward in FIG. 1),
The protruding pieces 42, 42 spread apart from each other, and are more firmly pressed against both side faces of the mounting groove 22 and the locking faces 25, 25. Therefore, once the fixing member 4 is inserted into the mounting groove 22, it hardly comes out of the mounting groove 22.

When the fixing member 4 is inserted into the mounting groove 22, one of the protruding pieces 42 (the left protruding piece 42 in FIG. 1) faces the mounting groove 22 and the locking surface 2
5 and the terminal 34 are clamped and fixed. Therefore, it is not always necessary to stitch and fix the terminal 34 to the plate portion 41, but it is desirable to fix the terminal 34 to the plate portion 41 in order to further securely fix the terminal 34 to the seatback frame 2 </ b> A.

The contact portion 43 has a substantially “recessed” cross section, and when the pair of projecting pieces 42, 42 abut against the locking surfaces 25, 25, the contact portion 43 is substantially at the bottom of the mounting groove 22. It comes to end. Thereby, the fixing member 4
Is prevented from moving toward the open side or the bottom side of the mounting groove 22. The width of the contact portion 43 is smaller than the width of the mounting groove 22, but larger than the thickness of the plate portion 41. The width of the contact portion 43 is set in the mounting groove 22 by the plate portion 4.
The reason why the thickness is made larger than 1 is as follows.

That is, when the seat back cover 3 is pulled in the direction of the arrow in FIG.
The left protruding piece 42 in FIG. 1 is elastically deformed so as to approach the other protruding piece 42 and comes off the locking surface 25. Then, the other end of the fixing member 4 (the end on the bottom side of the mounting groove 22) abuts on the side surface of the mounting groove 22 around the contact point between the other protruding piece 42 and the locking surface 25. To rotate. In this state, the pulling force on the seat back cover 3 acts as a moment on the other projecting piece 42. At this time, if the rotation angle of the fixing member 4 is large, the moment acting on the other protruding piece 42 increases, and there is a risk that the other protruding piece 42 is broken. When the other protruding piece 42 is broken, the fixing member 4 comes out of the mounting groove 22. However, a contact portion 43 wider than the lower end of the plate portion 41 is provided.
Is formed, the rotation angle of the fixing member 4 when the other end of the fixing member 4 abuts against the side surface of the mounting groove 22 can be reduced. Therefore, the moment acting on the other protruding piece 42 can be reduced, and the other protruding piece 42 can be prevented from breaking. Therefore,
The fixing member 4 can be prevented from falling out of the mounting groove 22.

Next, a case where the seat back cover 3 is fixed to the seat back 2 will be described. First, as shown in FIG. 3, the seat back 2 is inserted into the accommodation portion 31 of the seat back cover 3. Next, the respective cover portions 33 of the seat back cover 3 are made to extend along the back surface of the seat back 2. Thereafter, as shown in FIG.
4 is inserted into the mounting groove 22 together with the fixing member 4. Then, the protruding piece portion 42 of the fixing member 4 is prevented from coming off by the locking surface 25, and the seat back cover 3 is fixed to the seat back frame 2 </ b> A of the seat back 2. The fixing member 4 may be fixed to the seat back cover 3 before the seat back 2 is inserted into the seat back cover 3 or may be fixed after the insertion.

According to the fixing structure having the above structure, the terminal 34 can be fixed to the seat back frame 2A by simply inserting the terminal 34 together with the fixing member 4 into the mounting groove 22. Therefore, the terminal 34 can be fixed very easily. Moreover, since the fixing member 4 is inserted into the mounting groove 22, the metal wire does not protrude to the outside unlike fixing by the hog ring. Therefore, the appearance can be improved, and there is no hindrance when the seat back 2 is used as a table.

The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example, in the above embodiment, the terminal 34 is
Although it is fixed to the side surface on the part 21 side used as a table, it may be fixed to the opposite side surface. However, in such a case, since the fixing member 4 is not covered by the seat back cover 3, the projecting piece 42 of the fixing member 4
A decorative member is attached to the end of the
It is desirable to cover the mounting groove 22 and the fixing member 4 with a decorative member so that the mounting groove 22 and the fixing member 4 are not visible from the outside when the is inserted into the mounting groove 22.
