[0006]

SUMMARY OF THE INVENTION The present invention solves the problems of the conventional fixing method of the vehicle seat cover to the vehicle seat body, and helps to reduce the manufacturing cost.
An object of the present invention is to provide a method capable of fixing a vehicle seat cover to a vehicle seat body at an always accurate position and in an appropriately tensioned state.

[0007]

The above objects of the present invention are as follows:
A plurality of holes are provided at intervals along the periphery of the vehicle seat cover, foldable protrusions are provided at positions corresponding to the plurality of holes on the frame, and each protrusion is formed on the vehicle seat cover. This is achieved by a method for fixing a vehicle seat cover, characterized in that the plurality of holes are locked by inserting the holes into corresponding holes and changing a bending state to a position where tension is applied to the seat cover.

The vehicle seat cover is manufactured by forming knitting using a flat knitting machine, and in the course in which the hole is provided, only the number of needles corresponding to the length of the hole in the longitudinal direction is put in a rest state so that the stitch is not knitted. Therefore, it is preferable to provide holes. If the holes are formed in such a knitting process, the holes can be accurately provided along the peripheral edge of the vehicle seat cover, and as a result, the vehicle seat cover is properly tensioned to the vehicle seat at an appropriate position. Can be fixed in the state. It is more preferable to make the tongue-shaped piece the shape of the protrusion that locks each of the plurality of holes, because each hole is locked by the jaw of the tongue-shaped piece so as not to fall off.

A plurality of the holes are provided along the peripheral edge of the vehicle seat cover so that the vehicle seat cover can be accurately fixed to the vehicle seat while maintaining a proper tension. The number and the pitch of the holes may be arbitrarily selected according to the shape and size of the target vehicle seat, but it is usually preferable to provide 5 to 15 holes per vehicle seat and a pitch of 50 to 150 mm.

The present invention will be described in detail below with reference to the accompanying drawings showing an example of a method for fixing a vehicle seat cover of the present invention. FIG. 8 is a perspective view showing an example of a vehicle seat cover used in the fixing method of the present invention. The vehicle seat cover 11 shown in FIG. 8 is knitted in a U-shaped cross-section so that the vehicle seat body (not shown) is covered by forming knitting using a flat knitting machine. A plurality of slit-shaped holes 12 are provided in the course of knitting along the peripheral edge 11a of the vehicle seat cover 11. In addition, as shown in FIG.
It is preferable to provide a band-shaped stretch-resistant region 13 at a position slightly above. That is, since the vehicle seat cover 11 formed by knitting is usually knitted with a double jersey structure as a main structure, it tends to stretch a little, and therefore, the portion fixed to the vehicle seat by the plurality of holes described above is fixed. Seat cover 11 for knitted fabric vehicles
Wavy phenomenon is likely to occur. Therefore, the strip-shaped area 13
It is preferable to prevent the waving phenomenon by changing the front and back stitches of the double jersey structure to a knitting structure that is relatively hard to stretch, such as the plain knitting or the Ichimatsu pattern knitting.

FIG. 10 shows an example of a knitting procedure of the vehicle seat cover 11 with holes. In the portion knitting with the double jersey structure in Fig. 10, as shown in the first row in the case of the double jersey structure of Fig. 10, the yarn A is the front needle (Fig. 10 of the flat knitting machine of the two-row needle bed). The lower stitches) are used to form the front stitches, and the back stitches (upper needles in FIG. 10) are used to form the back stitches every other 1 × 1.
To form a rubber stitch. On the other hand, the thread B in FIG. 10 is a back stitch by the needle in which the thread A does not form a stitch in the back needle,
That is, a 1 × 1 flat stitch is formed. Thread A and Thread B 2
The carriage that feeds while moving along the row needle bed is shown in FIG.
As shown in the second row of 0, when moving in the opposite direction to the first row, that is, from right to left, the needle for knitting the thread B is the needle next to the needle used in the first row of knitting. is there. Thereafter, the same knitting is repeated to knit a double jersey knitted fabric into a desired shape by using the yarns A and B in such a manner that the plurality of needles in the two rows of needle beds mutually complement each other.

Next, the knitting of the portion where the holes are formed will be described. In the course in which the carriage shown in the first row of the perforated portion in FIG. 10 moves from left to right, the knitting similar to the double jersey structure described above is performed using the yarn A and the yarn B. In the next course in which the carriage moves in the opposite direction, that is, from the right to the left, the number of needles corresponding to the length of the hole is made to rest so that the stitches are not knitted, that is, a mistake is made (Fig. 1).
(See the second row of the 0 hole). As a matter of course, the knitting of the double jersey structure is performed in the same course in the portion where no hole is provided, so that a hole having a predetermined length is provided at a predetermined position along the peripheral portion of the vehicle seat cover.

When the knitting is restarted at the portion where the holes are provided, as shown in the first row of the knitting restart portion in FIG. 10, the knitting of the knitting is not performed in the course of the movement of the carriage from the left to the right. The course will be resumed and the stitches will be resumed after the next course. That is, as shown in the second row, the thread A is tacked to the needle missed to form the hole in the first course. Thereafter, bag knitting is knitted using the yarn A for 3 to 5 courses (3 courses of bag knitting in FIG. 9). During this time, the yarn B is not knitted. In the next course, using the yarn A and the yarn B, the knitting shown in the second row in the case of the double jersey structure of FIG. 10 is performed, and thereafter, as shown in the double jersey structure part of FIG. The formation of the vehicle seat cover is completed by repeating the formation of the predetermined course.

FIG. 11 shows another example of the knitting procedure of the vehicle seat cover 11 with holes. The knitting procedure shown in FIG. 11 is the same as the knitting procedure shown in FIG. In the knitting procedure of the perforated portion shown in FIG. 11, the procedure (i)
The yarn A and the yarn B are knitted until just before the hole formation start point, and the needles are made to miss both the yarn A and the yarn B at the portion corresponding to the rear hole. At this time, the ends of the yarn A and the yarn B are held by the yarn guide device. The next course moving from the right to the left of the carriage will be an empty course. In step (ii), the first stitch is knitted with the front needle using the yarn A, and the stitch is transferred to the rear needle at the position shown in the next course. procedure
In (iii), transfer with thread B. That is, the first stitch is knitted with the rear needle using the thread B, and transferred to the front needle at the position shown in the figure in the next course. In the next step (iv), the transfer with the thread A is performed in the same manner as in the step (ii), but from the time of the step (ii), only one stitch is moved in the direction toward the end point of the hole (to the right in FIG. 11) to the first stitch. After knitting, transfer to the rear needle in the next course. In the procedure (v) as well, the first stitch is knitted by the back needle with the thread B similarly to the procedure (iii), but similarly, the stitch is moved by one stitch toward the end point of the hole, and the stitch is transferred to the front needle in the next course. In this way, step (iv) and step (v) are repeated until the end of the hole. As a result, when the knitting method of Example 2 shown in FIG. 11 is used, the edges of the holes become stitches which are connected in a zigzag manner, and the stitches are reinforced as if they were oversewn. That is, in the hole portion, the outer material and the lining are closed by the knitting method of Example 2, but the outer material and the lining are left open by the knitting method of Example 1 shown in FIG. FIGS. 10 and 11 show an example for forming holes,
Various knitting methods can be used as long as they can form a hole having a size into which a frame protrusion of a vehicle seat described later can be inserted. Also, the yarns used are two types of yarn A and yarn B in the above example, but three or more various colored yarns may be used for knitting.

Next, a method for mounting and fixing the vehicle seat cover 11 with holes formed as described above to the vehicle seat will be described. As shown in FIGS. 12 and 13, the vehicle seat cover 11 is a frame 13 on which the mold pad 4 is mounted.
On top of. On the other hand, the frame 13 is provided with a projecting portion 13a corresponding to the position of the hole 12 of the vehicle seat cover 11. The protrusion 13a has a shape as shown in FIG. 14A and is provided so as to be able to be cut and raised from the main body of the frame 13, and it is preferable that the protrusion 13a has projecting jaws on both sides. See also FIG.
It may be formed in the shape of a tongue as shown in FIG. In the case of FIG. 12, the protruding portion 13a is raised in the counterclockwise direction and passed through the hole 12 of the vehicle seat cover 11, and further bent in the counterclockwise direction to fix the vehicle cover sheet in a state where tension is applied. On the other hand, in the case of FIG. 13, the projecting portion 13a is passed through the hole 12 of the vehicle seat cover 11 with the projecting portion 13a being raised in the clockwise direction, and the projecting portion 13a is then mounted on the frame 1
Return to the surface that matches the surface of 3. Also in this case, the vehicle seat cover is fixed to the frame 13 in a tensioned state.

[0016]

The vehicle seat cover fixing method of the present invention is provided with a plurality of fixing holes in the vehicle seat cover itself.
A structure is adopted in which a protrusion extending from the frame is inserted into this hole, and the vehicle seat cover is locked by changing the bent state of the protrusion to a position where tension is applied to the vehicle seat cover. When fixing to the seat for use, auxiliary materials such as wires and cores are not required, and sewing work accompanying the use of the auxiliary materials is not required. As a result, it helps to reduce the manufacturing cost of the vehicle seat to which the seat cover is attached. Further, since the positions of the holes can be accurately determined at the time of manufacturing the vehicle seat cover, the seat cover can be attached and fixed accurately, and the occurrence of product defects such as poor appearance can be prevented.
