Description

[Detailed Description of the Invention] The present invention relates to a seat skin for a two-wheeled vehicle.

Conventionally, this type of seat skin is usually formed into a three-dimensional shape that can be covered on a cushion body by cutting skin material into a predetermined shape and sewing it with a sewing machine or the like. In this sheet skin, the perforations at the joints enhance the design effect and significantly improve the product value, but as the cushion body is coated, the seams widen and gaps are created where rainwater can leak. It has the disadvantage that it can penetrate and rot the cushion body. In contrast, heretofore, three-dimensional molding of skin materials has been performed by welding instead of sewing. This welding process allows the sheet skin to be formed so that no gaps are created at the seam, but on the other hand, there are no perforations at all, which impairs the design.

An object of the present invention is to provide a seat skin for a two-wheeled vehicle in which a thread-like border pattern is integrally provided at a seam where skin materials are welded and joined.

That is, in the motorcycle seat skin according to the present invention, the thread-like border pattern is provided by intermittently protruding molten burrs along the seam line of the skin material.

This will be explained below based on the illustrated embodiments.

The illustrated seat skin A is formed into a three-dimensional shape that can be covered with the cushion body B by welding and joining a plurality of skin materials a ₁ , a ₂ . . . so as to have a rise corresponding to a waist rest. When welding and joining each skin material, we use a high-frequency welder, electric heating,
Ultrasonic heating can be performed, for example, by stacking the skin materials a ₁ and a ₂ with their front surfaces facing each other and pressing their edges from the back sides. At that time, the skin material
On a ₁ and a ₂ , burrs c ₁ due to melting of the materials are intentionally made to appear at least on the surface side. This burr c ₁ is surface plate d ₁
The amount of ejection can be controlled by appropriately adjusting the pressing time and clamping force by the pressing rod _d2 and the seam by providing a partial cutout on the pressing surface of the pressing rod d, for example, on the pressing line. It is possible to protrude intermittently along the line. In addition to the burr c ₁ that protrudes toward the surface side, a small amount of burr c ₂ may also be made to protrude from the edge side.

In the motorcycle seat skin constructed in this way,
The joints of the skin materials a ₁ , a ₂ ... are joined by welding without any gaps, and there are no burrs.
c ₁ is formed intermittently along the seam line, giving it a thread-like border pattern. Also,
This burr c ₁ comes to firmly join each joint portion of the skin materials a ₁ , a ₂ . . . and improves the peel strength together with the burr c ₂ .

As described above, according to the motorcycle seat skin according to the present invention, it is possible to prevent the intrusion of rainwater, prevent peeling at joints, and increase the product value by improving the design.
