It is a typical front view which shows two cables and one strap connected to two cables by sewing. It is a typical front view which shows the example connected to two cables 2a and 2b by sewing each of the main strap part and branch strap part which comprise a strap.

A strap according to an embodiment of the present invention will be described with reference to the drawings.
First, a flexible string-like strap 1 that is operated by a vehicle seat occupant and a cable 2 to which the strap 1 is connected will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a schematic front view showing the cable 2, and FIG. 2 is a schematic front view showing the strap 1 having the slit 1a.

The cable 2 is connected to a reclining device (not shown) that constitutes a vehicle seat (not shown), and is configured such that the lock of the reclining device is released when the cable 2 is pulled.
As a specific configuration, the cable 2 includes an inner cable 20 and an outer cable 21 that covers the inner cable 20 as shown in FIG. By pulling the inner cable 20 in the direction protruding from the outer cable 21, the lock of the reclining device (not shown) is released.
A cylindrical cable end 20 a that extends perpendicularly to the continuous direction of the inner cable 20 is formed at the tip of the inner cable 20. In addition, this extending direction is also called a cylinder axis direction below. And cable end 20a is formed so that it may become long in the direction of a cylinder axis. The strap 1 described below is connected to the cable end 20a.

  The strap 1 is made of a synthetic fiber material and is made of non-metal, and is connected to one cable 2 so that a lock of a reclining device (not shown) connected to the cable 2 can be connected via the cable 2. Has a function to cancel. That is, the strap 1 is connected to the cable 2 and thus has a function as an operation unit that is suitably arranged for the operation of the seated person.

In the strap 1, a slit 1 a is formed at the center in the width direction in a direction along the extending direction of the strap 1.
The slit 1a is for passing the cable end 20a of the cable 2 from the back surface to the front surface of the strap 1, and is formed by heat cut processing so that fraying does not occur due to contact with the cable end 20a.
The cable end 20a is passed through the slit 1a and is sewn as described later, whereby the cable 2 and the strap 1 are connected.

  Next, a method for sewing the strap 1 will be described with reference to FIGS. Here, FIG. 3 is a schematic front view showing a state in which the cable end 20a is passed through the slit 1a, and FIG. 4A is a schematic front view showing a state in which the strap 1 is bent so as to wrap the cable end 20a. FIG. 4B is a schematic side view showing a state where the cable end 20a is bent so as to wrap, and FIG. 5 is a schematic front view showing a state of the strap 1 connected to the cable 2 by sewing.

(Through process)
First, as shown in FIG. 3, the cable end 20a is passed through the slit 1a. Here, in order to pass the cable end 20a having a cylindrical shape as described above from the end portion having a small area through the slit 1a, the end portion of the cable end 20a is inserted into the slit 1a in the cylindrical axis direction, and FIG. Inside, let the cable 2 pass from the back side of the strap 1 to the front side.

(Wrapping process)
Next, as shown in FIG. 4A and FIG. 4B, after the direction of the cable end 20a is changed so that the cylindrical axis direction of the cable end 20a coincides with the width direction of the slit 1a, the terminal 1b of the strap 3 is connected to the cable end. It is folded at the folding portion 1d so as to wrap 20a. In this way, the direction of the cable end 20a is changed between insertion and folding, and the width W of the cable end 20a protrudes greatly from the slit 1a at the time of folding, and in this state, sewing is performed in a later process, It is possible to prevent the cable end 20a from falling out of the slit 1a.

(Joining process)
Next, as shown in FIG. 5, the terminal 1b to be folded back and the facing portion 1c facing the terminal 1b are joined by sewing so as to form a Z-shaped sewing line L1. Here, the sewing line L1 and the sewing lines L2 and L3 described later correspond to the joining lines according to the present invention. At this time, one of two parallel sides forming the Z-shaped sewing line L1 crosses (intersects) the slit 1a vertically (orthogonally).

Thus, by sewing so as to cross the slit 1a, the expansion of the slit 1a can be suppressed, and the cable end 20a can be prevented from falling off the slit 1a. Furthermore, since the sewing line L1 is formed at a portion other than the portion crossing the slit 1a, the number of stitching portions is increased, and the joining of the terminal 1b to which the strap 1 is turned back and the facing portion 1c is further strengthened. Can do.
In particular, it is preferable to form the sewing line L1 so that the inner surface in contact with the cable end 20a defined by the folded portion 1d of the cable end 20a and the sewing line L1 is along the peripheral surface of the cable end 20a. In this way, since the cable end 20a can be sandwiched between the folded portion 1d and the sewing line L1, the swing of the cable end 20a can be restricted, and the cable end 20a can be prevented from falling off from the slit 1a. Because.

(First modification)
In the above embodiment, the example in which the sewing line L1 between the terminal 1b to which the strap 1 is turned back and the facing portion 1c is Z-shaped has been described, but the present invention is not limited to such a configuration.
For example, it may be sewn in a ribbon shape like the sewing line L2 according to the first modification shown in FIG. Here, the ribbon shape is a shape formed of two parallel lines extending so that at least one side crosses the slit 1a and a line that diagonally connects the opposite ends of the two sides. Say.
According to such a sewing line L2, since there are more sewing locations than the sewing line L1, and it is a shape which has symmetry, sewing can be strengthened more.

(Second modification)
Although the strap 1 according to the above embodiment has been described as being connected to only one cable 2, the present invention is not limited to such a configuration. Next, with reference to FIG. 7, one strap 10 according to a second modification connected to the two cables 2a and 2b will be described.

  Since the strap 10 is connected to the two cables 2a and 2b, the strap 10 has a function of simultaneously unlocking the reclining device (not shown) and the seat slide device respectively connected to the two cables 2a and 2b.

The strap 10 is formed with two slits 10a and 10b in the direction along the extending direction at the center in the width direction.
The two slits 10a and 10b are for passing the cable ends 20a and 20b of the two cables 2a and 2b. The cable end 20a is passed through the slit 10a, and the cable end 20b is passed through the slit 10b. Thus, the cables 2a and 2b and the strap 10 are connected by sewing.

  As shown in FIG. 7, the strap 10 is sewn so as to form a sewing line L3. Specifically, the sewing line L3 is formed in a Z shape, and at least a part of the slits 10a and 10b of the portions where the cable ends 20a and 20b of the two cables 2a and 2b are inserted are at least partially. It is formed so as to cross all at once. As described above, since the sewing line L3 is formed so as to cross the slits 10a and 10b together, the labor of sewing is reduced.

  On the other hand, the strap 10 may be sewn in a Z-shape so as to cross the slits 10a and 10b for each of the cables 2a and 2b, as in the case of the strap 1. In this way, by sewing each of the slits 10a and 10b, the sewn portions can be concentrated, so that the cable ends 20a and 20b can be more reliably held.

(Third Modification)
Finally, a strap 3 according to a third modification will be described with reference to FIG. Here, FIG. 8 is a schematic front view showing an example in which each of the main strap portion 30 and the branch strap portion 31 constituting the strap 3 is connected to the two cables 2a and 2b by sewing.

The strap 3 according to the third modification includes a main strap portion 30 and a branch strap portion 31 that is branched and attached to the main strap portion 30 by a stitching portion 3a. The strap part 30 is connected to the cable 2a, and the branch strap part 31 is connected to the cable 2b.
In this way, the main strap portion 30 and the branched branch strap portion 31 are formed so as to be separated from each other, so that the main strap portion 30 or the branch strap portion 31 can be connected to the cables 2a and 2b. The range becomes wider.

Moreover, according to such a structure, even if the cable ends 20a and 20b of the cables 2a and 2b are at positions away from each other, without changing the length of the cables 2a and 2b whose length is difficult to adjust, It can connect suitably by adjusting the length of this strap part 30 or the branch strap part 31 with easy adjustment of length.
In particular, in the vehicle seat, the positions of the cable ends 20a and 20b of the cables 2a and 2b connected to the reclining device (not shown) and the locking device of the slide rail are often different, so that the length can be easily adjusted. A strap 3 is preferred.

  The above embodiment is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the spirit of the present invention, and of course, the present invention includes equivalents thereof.

  For example, in the said embodiment, it demonstrated as what has the effect | action which joins the terminal part of the folding | turning part of a strap by sewing, restrict | limits the opening part of a slit, and restrict | limits a cable end falling out from a slit. However, the present invention is not limited to the joining by sewing, and the end of the folded portion of the strap may be joined by ultrasonic welding or the like instead of sewing. In this way, the end of the folded portion of the strap can be joined in a shorter time than sewing.
