[0047] Hereinafter, an embodiment of a seat for a saddle-ride type vehicle of the present invention will be described with reference to the drawings. Saddle-ride type vehicles include, for example, motorcycles, four-wheeled buggies, jet skis, snowmobiles, etc. In the following embodiment, a seat for a motorcycle will be described.

[0048] As shown in Figures 1 to 5, the seat 1 has a top plate 2, a plurality of wires 3, 4, and 5, a frame 6, and a bottom plate 7. The top plate 2 is flexible and forms a seating surface 2A. The plurality of wires 3, 4, and 5 are arranged along the top plate 2 and provide rigidity to the top plate 2. The frame 6 is connected along the edge of the back surface of the top plate 2. The bottom plate 7 is connected to the frame 6 and is disposed below the top plate 2 with a space therebetween.

[0049] The top plate 2 is made of a resin material. The wires 3, 4, and 5 are made of a metal. The frame 6 and the bottom plate 7 are made of a resin material or a metal. The top plate 2 has higher flexibility than the frame 6 and the bottom plate 7.

[0050] 1 and 3, the top plate 2 has a mesh-like shape and multiple ventilation holes 11 that penetrate through the thickness. The top plate 2 has a main surface 13 that faces generally in the vertical direction, left and right side edge portions 14 that are provided on the left and right sides of the main surface 13 and extend downward, and a rear edge portion 15 that is provided behind the main surface 13. The rear edge portion 15 has left and right corner portions 16 that protrude upward. The left and right corner portions 16 are formed in a triangular shape.

[0051] The front half of the top plate 2 is curved so that the center is convex upward when viewed from the front, and the rear half of the top plate 2 is inclined upward toward the rear.

[0052] At least one groove 19 recessed downward is formed on the upper surface of the top plate 2. In this embodiment, two grooves 19, one in the front and one in the rear, are provided. The two grooves 19 are arranged side by side in the front-to-rear direction and extend in the front-to-rear direction through the center of the main surface 13 in the left-to-right direction.

The bottom plate 7 is curved so as to be convex downward when viewed from the left-right direction. Mainly, the main surface portion 31 of the bottom plate 7 is curved so as to be convex downward when viewed from the left-right direction. This forms a space between the main surface portion 31 of the bottom plate 7 and the main surface portion 13 of the top plate 2, allowing the main surface portion 13 of the top plate 2 to elastically deform.

[0057] An edge 32 of the bottom plate 7 is joined to the frame 6. As shown in FIG. 6 , a plurality of joining holes 34 are formed in the edge 32 of the bottom plate 7. The frame 6 is provided with a plurality of press-fit protrusions 35 that are press-fitted into the plurality of joining holes 34. The frame 6 and the bottom plate 7 are joined to each other by press-fitting each press-fit protrusion 35 into the corresponding joining hole 34. This prevents the frame 6 and the bottom plate 7 from shifting, and the top plate 2 is reliably supported by the frame 6 and the bottom plate 7.

[0058] The bottom plate 7 has a plurality of reinforcing ribs 37 protruding upward and a plurality of recesses 38 defined by the reinforcing ribs 37. The reinforcing ribs 37 improve the rigidity of the bottom plate 7. A plurality of second drain holes 39 penetrating in the thickness direction are provided in the bottom surface 19A of the recesses 38. Liquid that has entered the recesses 38 is discharged from the corresponding second drain holes 39.

[0059] 2, the multiple wires 3, 4, 5 include a horizontal wire 3 that extends in the left-right direction in the center of the top plate 2 in the front-rear direction and is curved so as to be convex upward. The multiple wires 3, 4, 5 also include at least one vertical wire 4 that extends in the front-rear direction in the center of the top plate 2 in the left-right direction. In this embodiment, two vertical wires 4, one on the left and one on the right, are provided.

When viewed from above, each rear wire 5 is disposed at a position that does not overlap with the plurality of air vents 11. In other words, when viewed from above, each rear wire 5 is disposed at a position that avoids the plurality of air vents 11.

[0064] As shown in Figures 3, 9, and 10, each of the left and right vertical wires 4 penetrates the top plate 2 from front to rear, and has a front end 4A that penetrates the front portion of the bottom plate 7 from front to rear, and a rear end 4B that penetrates the rear portion of the bottom plate 7 from front to rear. Each vertical wire 4 extends front to rear through the front and rear grooves 19. A portion of each vertical wire 4 is disposed within the front and rear grooves 19 and is exposed on the upper surface of the top plate 2. Each vertical wire 4 penetrates the front wall 19B and the rear wall 19C that define the front and rear grooves 19. Each vertical wire 4 improves the rigidity of the front and rear grooves 19 and the top plate 2. The front end 4A and the rear end 4B of each vertical wire 4 may be bonded to the bottom plate 7 by adhesive or welding. Alternatively, the front end 4A and the rear end 4B of each vertical wire 4 may be crimped to bond each vertical wire 4 to the bottom plate 7.

The viewer can see the light emitted by the lighting device 61 through the plurality of air vents 11.

[0076] In the seat 1 according to the embodiment, the lateral wires 3 are positioned near the ischial bones of the occupant, so the top plate 2 can efficiently support the weight of the occupant. Therefore, the seat 1 for a saddle-ride type vehicle, which has the top plate 2 that forms the seating surface 2A, can stably support the occupant.

[0077] The frame 6 provides rigidity to the edge of the top plate 2, allowing the top plate 2 to maintain its shape. Furthermore, since the lateral wires 3 and the left and right rear wires 5 are connected to the frame 6, the lateral wires 3 and the left and right rear wires 5 can stably support the occupant.

[0078] Since the vertical wires 4 pass through the bottom plate 7 and the top plate 2 is supported by the bottom plate 7 and the vertical wires 4, the top plate 2 can stably support the occupant.

[0079] Although the description of the specific embodiment has been completed above, the present invention is not limited to the above embodiment and can be widely modified and implemented. For example, the top plate 2 and frame 6 may be integrally molded by two-color molding. In this case, as shown in FIG. 20 , the connecting portion 6D protruding upward from the frame 6 may pass through several ventilation holes 11 and wrap around to the upper surface of the top plate 2, thereby being inseparably connected to the ventilation holes 11. This prevents the frame 6 and the top plate 2 from shifting, ensuring that the top plate 2 is securely supported by the frame 6.
