Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a steering wheel equipped as a steering wheel for automobiles, ships and the like.

[0002]

[Prior art]

 Generally, in a steering wheel for an automobile or the like, a gripping portion is covered with a cover material such as genuine leather or synthetic leather cut into a predetermined shape, and the ends of the cover material are sewn along the circumferential direction of the gripping portion. As a result, there are some cases in which the handshake portion is covered with a cover material.

Conventionally, in order to sew between the ends of the covering material, it is usual to butt each edge and perform zigzag stitching. However, this is not preferable in terms of appearance because the sewing thread is exposed on the surface side, and it also affects the grip feeling of the handshake.

In order to eliminate the above-mentioned drawbacks, each end portion of the covering material is bent to a required width on the back surface side, and zigzag stitching is performed between the bent edges on the back surface side of the covering material. Can be prevented from being exposed on the surface side of the cover material. However, in this case, the width of the end portion bent to the back surface side of the covering material greatly raises the covering material, so that the appearance and feel due to the rising will be impaired.

[0005]

[Problems to be solved by the device]

 The present invention provides a steering wheel improved in that the appearance and feel of the handshake can be maintained well by stitching the ends of the outer cover with thread sewing and integrally attaching the handshake with the outer cover. The purpose is to do.

[0006]

[Means for Solving the Problems]

 In the steering wheel according to the present invention, a sewable surface covering material such as genuine leather or synthetic leather cut into a predetermined shape is put on the handshake, and the ends of the surface covering are arranged along the circumferential direction of the handshake. The handshake part is attached with a cover material by sewn together, and the edge of the cover material is thinned toward the edge, and a seam of a straight stitch is provided along the end of the cover material, and The edge near the edge including the sewing thread part is bent to the back side of the cover material, and the zigzag stitching thread is passed through the stitches of each straight stitch on the back side of the cover material to align the thin portions with each other and the stitch concerned. It is configured by using a zigzag sewing thread and pulling it between the thin portions.

[0007]

[Action]

 With this steering wheel, the sewing thread of the zigzag stitch is located at the position bent into the back side of the cover material along with the seam of the straight stitch provided along each end of the cover material, so the sewing thread is on the front side of the cover material. No exposed position. Also, the thin-walled part is joined with the zigzag sewing thread, and the thickness does not rise greatly because each sewing thread is located between the seams of the thin-walled part. Therefore, in this steering wheel, the sewing thread is located on the back surface side of the covering material, and the stitching portion does not rise largely in terms of thickness, so that the appearance and feel can be improved.

【Example】

 1 to 4 show an assembling process of an automobile steering wheel, referring to the attached drawings. In this assembling process, a steering wheel having a ring-shaped handshake is constructed, and a cover material made of a sewable material such as genuine leather or synthetic leather is attached to the handshake.

FIG. 1 a shows a covering material 1 cut into a predetermined plane shape necessary for enclosing a ring-shaped handshake portion. The cover material 1 includes a band portion 1a that wraps the ring-shaped handshake in the circumferential direction, and a projecting width portion 1b that wraps the base of the spoke portion facing the center side from the inner circumference of the handshake portion. It has been cut and molded. Further, as shown in FIG. 1b, this cover material 1 is formed with thin-walled portions 2 ... The thin-walled portion 2 ... is located inward or near the thin-walled portion 2, and the straight-line stitches 3 are provided along the edge by sewing.

FIG. 2a shows the back surface side of the facing material 1, that is, the inner surface side in contact with the surface of the handgrip portion. As shown in FIG. 2b, this cover material 1 is edge-molded by bending the ends from straight seams 3 ... along the edge and fixing the bent portion 1c with an adhesive.

In FIG. 3, the covering material 1 obtained from each step of FIGS. 1 and 2 is put on the handgrip G of the steering wheel, and the end portions of the covering material 1 are sewn along the inner peripheral direction of the handgrip G. The thread sewing process is shown. In this thread sewing step, zigzag sewing is performed by alternately passing the sewing thread 4 through the stitch 3 at each end located on the back surface side of the cover material 1 with the sewing needle P.

FIG. 4 a shows a final step in which the ends of the covering material 1 are sewn together by pulling the sewing thread 4 for zigzag sewing. In this stitching state, as shown in FIG. 4b, the stitches 3 and 3 of the straight stitch are pulled in one direction by the sewing thread 4 of the zigzag stitch, and the ends of the covering material 1 are butted against each other at the thin portions 2 and 2. ing. The zigzag stitching thread 4 is located between the seams of the thin portions 2 and 2, and the zigzag stitching thread 4 and the straight stitches 3 and 3 are in contact with the surface of the handshake portion G. Located in.

In the steering wheel configured as described above, the stitches 3 of the straight stitches and the sewing threads 4 of the zigzag stitch are not exposed on the surface side of the cover material 1, and the end portion of the cover material 1 is joined at the thin portion. By doing so, it is possible to prevent the wall thickness from rising too much. As a result, it is possible to assemble a product that is good in appearance and a product that is also good in touch.

[0014]

[Effect of device]

 As described above, according to the steering wheel of the present invention, even when the end portion of the covering material is sewn by thread sewing, the seam is not exposed on the front surface side and the seam portion is thickly raised. Since it is not present, the appearance and feel can be improved.
