DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a steering wheel cover (hereinafter referred to as "cover") and a steering wheel of the present invention will be described below with reference to the drawings. FIG. 1 shows a perspective view of one embodiment of the cover of the present invention. The cover 1 in this figure is formed in an annular shape by sewing leather band-shaped sheets 2 to 5 together. Protrusions 6 for spoke portions of the steering wheel are provided on the left and right belt-shaped sheets 3 and 5. A notch 7 is formed at the boundary between the convex portion 6 and the belt-shaped sheet 3.
Is provided.

Next, a method of manufacturing the cover 1 shown in FIG. 1 will be described with reference to FIGS. FIG. 2 shows a plan view of each band-shaped sheet alone. A belt-like sheet as shown in FIGS. 2A to 2C is obtained by cutting a leather sheet. Both ends 2a of the belt-shaped sheet 2 shown in FIG. 2A are cut in a convex shape.

The belt-shaped sheet 3 shown in FIG. 2B is provided with a spoke-shaped convex portion 6 and two notches 7 at each position. Although not shown, the belt-shaped sheet 5 is symmetrical to the belt-shaped sheet 3. One end 3a is cut into a convex shape and the other 3b is cut into a concave shape.

When mounted on the steering wheel, the belt-shaped sheets 3, 5 are portions corresponding to the left and right grips that are frequently used during driving. Therefore, it is preferable to perform drilling or embossing over the entire surface. By performing such processing, the familiarity with the hand can be improved, and the hand can be prevented from slipping during driving. The belt-shaped sheet 4 shown in FIG.
Is cut into a concave shape.

After the production of the belt-like sheets, the ends of the respective belt-like sheets are sewn and joined. FIG. 3 shows a joining portion between the belt-like sheets 2 and 3 and between the belt-like sheets 2 and 5. The band-shaped sheets 2 and 3 are joined by butting and sewing the concave end 3b of the band-shaped sheet 3 and the convex end 2a of the band-shaped sheet 2 together. Similarly, the belt-shaped sheets 2 and 5 are joined. Reference numeral 8 denotes a seam. Since the stitched portion joins the concave end and the convex end, it is formed in a substantially U-shape with respect to the longitudinal direction of the belt-shaped sheet. Thus, approximately U
The reason why the shape is formed into a letter shape is that when the cover is mounted on the steering wheel, the seam becomes slanted when the steering wheel is viewed from the front, and the appearance is good.

If the concave end and the convex end of each of the belt-like sheets 2 to 5 are joined by the same method, the annular cover 1 as shown in FIG. 1 can be manufactured. It is preferable to provide stitches 9 in the longitudinal direction of the cover by stitching as shown in FIG. In this case, when the cover is mounted on the steering wheel, the seam 9 is provided so that the seam 9 is located on the inner peripheral side of the wheel portion. When the cover provided with the stitches 9 is attached to the steering wheel, the appearance is the same as that of the skin-wrapped steering wheel to which the leather is sewn and fixed in advance.

Next, a method of attaching the cover to the steering wheel will be described with reference to FIGS. The steering wheel 10 shown in FIG.
It is an example of the one provided with. The cover 1 is mounted without removing the steering wheel 10 while keeping it fixed in the vehicle. First, the inside of the annular cover 1 shown in FIG.
As shown in FIG. 4A, the steering wheel 10 is fitted on the outer peripheral portion of the wheel portion 10a. At this time, the convex portion 6 of the cover 1 is positioned in accordance with the corresponding spoke portion 10b of the steering wheel 10. The cover 1 in this drawing is illustrated as having left and right portions subjected to perforation or embossing.

FIG. 4B is a cross-sectional view taken along line II of FIG. 4A, and shows a state where the cover 1 is fitted to the wheel portion 10a of the steering wheel. In this state, the adhesive is applied to 13 parts of the wheel portion 10a and 1
4, 15 parts are applied over the entire circumference using a brush or the like.

It should be noted that the reason why the adhesive is not applied over the entire surface of the cover 1 is that the partial application is sufficient for fixing and that the cover 1 does not have an applied portion. This is because 1 becomes familiar with the wheel portion 10a.

Further, the adhesive is not applied to the spokes 10b, but is applied only to both ends of the convex portion 6 of the cover 1. At this time, for example, an adhesive is applied to the front surface on the end surface 16 side, and an adhesive is applied to the back surface on the end surface 17 side. This is because the fixing of the convex portion 6 in the spoke portion 10b is
This is because the end face 16 and the end face 17 of the projection 6 are overlapped and adhered to each other on the back surface. According to such a bonding method, it is not necessary to apply an adhesive to the spoke portions 10b, so that the work is easy, and the bonding is ensured because the spoke portions 10b are laminated and pasted.

After the application of the adhesive, the cover 1 is first adhered to the wheel portion 10a. Specifically, the upper end 11 and the lower end 12 are abutted and bonded. Next, cover 1
Is fixed to the spoke portion 10b. FIG. 5 shows a perspective view of the back surface of the spoke portion 10b. Since the notch 7 is provided in the convex part 6, the convex part 6 can wrap and wrap the spoke part 10b. The end face 16 and the end face 17 of the convex portion 6 are superposed and adhered. The airbag unit 1 shown in FIG.
The tip of the convex portion 6 is inserted into the gap 18a between the spoke 8 and the spoke portion 10b.

It is preferable that a portion of the outer peripheral portion of the rear surface of the convex portion 6 is previously peeled off in the thickness direction so that the outer peripheral portion has a smaller thickness than the other portions. In FIG.
It shows an example of a state in which the outer peripheral portion of the convex portion 6 is peeled off,
19 is a stripping surface. By doing so, the protruding portion at the end face of the overlapped portion can be made thinner, so that peeling of the end face caused by touching during operation can be prevented.
Further, it becomes easy to insert the distal end portion of the projection 6 into the gap 18a shown in FIG.

It is preferable to use glue as the adhesive.
Glue is an adhesive obtained by boiling and extracting animal bones and the like. The use of glue has good adhesive strength.
In addition, since it is not completely cured, it has good familiarity with the hand through the cover during operation.

FIG. 7A is a perspective view showing a state in which the cover 1 has been mounted on the steering wheel 10. FIG.
B is a cross-sectional view taken along line II-II of FIG. 7A. As shown in this figure, since the upper end 11 and the lower end 12 of the cover 1 abut against each other, the upper end 11 and the lower end 12
Is on the same plane and has no protrusion. As described above, the adhesive 20 is applied to the butted portion. Also, since the butting portion is on the inner peripheral side of the wheel portion 10a, the steering wheel 10 is in a position that is not noticeable when viewed from the front. Further, a stitch 9 (FIG. 7A) formed by stitching is formed on the cover 1 over substantially the entire inner circumference.

For this reason, the appearance is the same as that of a leather steering wheel in which leather is sewn and fixed in advance. Therefore, the aesthetic appearance and the operability can be improved without replacing the steering wheel itself, and a steering wheel having the same appearance as the skin-wrapped steering wheel can be obtained.

[0035]

As described above, according to the cover of the present invention, the belt-like sheet is formed in an annular shape, and the belt-like sheet is provided with the convex portion integral with the belt-like sheet and the cut portions provided on the left and right sides of the convex portion. Thus, a steering wheel having excellent aesthetics and operability can be obtained without replacing the steering wheel itself.

Next, according to the steering wheel of the present invention, the above-mentioned cover is fixed to the wheel portion with the band-shaped sheet abutting the ends in the longitudinal direction by an adhesive, and the spoke portion is fixed to the band-shaped sheet. Since the convex portion is wound around the spoke portion and fixed with an adhesive, the appearance and the operability are excellent.
