Description

[Detailed Description of the Invention] This invention relates to a skin joint structure for backrests of motorcycles and similar articles.

In conventional joining structures for motorcycle backrests, etc., a cushioning material such as a soft foam material is filled inside the skin of the backrest, etc., and then the joining part of the skin is sandwiched and joined with a metal joining ring. , and was generally held on the seat body by a support arm.

When such a joining ring is used for a backrest, etc., as shown in Figure 3, the ring protrudes (protrudes outward) from the surface of the skin of the joined part, causing rust, rust, etc.
There were other problems with the appearance.

This invention aims to solve the above-mentioned problems, and its gist is that in a skin joint structure such as a backrest, in which the skin is loaded with a cushion material and the skin is sandwiched and joined by a joining ring,
This is a skin joint structure, such as a backrest, characterized by covering the outward protrusion of the joint ring with a soft material.

An embodiment of this invention will be described below based on the drawings.

FIG. 1 is a perspective view of a motorcycle seat having a backrest, etc., where 1 is a seat body, 2 is a backrest, etc., and 3 is a support arm that holds the backrest, etc. 2 on the seat body 1.

FIG. 4 is a partial cross-sectional perspective view taken along the line in FIG.
A cushion material 5 such as urethane foam is loaded. Then, both ends of the skins 4, 4 are brought into contact with each other and joined by joining rings 6, 6, . . . .
The joining ring 6 is generally made of metal, but is not limited to this, and may be made of hard resin as long as it has a sharp tip that can penetrate the epidermis.
FIG. 5 is a partial sectional view taken along the - line in FIG. 4. As shown in FIG. 5, the metal joining rings 6, 6, . . . used in this embodiment are used to join the skin 4 of the backrest 2, and
The upwardly protruding (outwardly protruding) rings 6, 6, . . . are entirely covered with a soft material 7 such as vinyl chloride sol. In this case, first, the joining rings 6, 6...
After piercing the outer skins and binding the skins together, a soft material, such as vinyl chloride sol, is applied onto the joining rings 6, 6, . . . and hardened by heating or the like. When the vinyl chloride sol is cured, a resilient and flexible coating layer is formed. As a result, the joining ring 6 is protected from rust and corrosion, and discomfort caused when the joining ring 6 comes into direct contact with the body is eliminated. It also has a waterproof effect that prevents rainwater from entering through the joints of the skin. Therefore, it is possible to obtain a skin-jointed part such as a backrest that does not rust and has a good appearance.

Note that FIG. 6 is a diagram of a person riding on the backrest seat of a motorcycle using the backrest joint structure according to this embodiment.

The soft material is not limited to the vinyl chloride sol used in the above embodiments, but any material having similar properties may be used.

Furthermore, the target articles are not limited to the above embodiments, but can also be applied to similar articles such as backrests and headrests for automobiles, furniture, and the like.

As described above, by using the joint structure according to the present invention, a sheet with a backrest having a joint portion that looks good and feels good can be obtained. Furthermore, if the joining ring is made of metal, rust etc. can be prevented or avoided.

[Brief explanation of the drawing]

Figure 1 is a motorcycle seat with a backrest, Figure 2 is an explanatory diagram of loading cushioning material into the skin of the backrest, Figure 4 is a perspective view taken from the - line in Figure 1, and Figure 5 is the figure 4. FIG. 6 is a partial cross-sectional view taken along the line -, and is a view of a person riding on a seat using the present invention. Note that FIG. 3 is a conventional one and shows the joint ring structure at the same location as FIG. 5. 1: Seat body, 2: Backrest, 3: Support arm, 4: Outer skin, 5: Cushion material, 6: Joining ring, 7: Soft material.
