Description

[Detailed description of the invention] The present invention relates to a seat attachment device for a motorcycle or the like.

2. Description of the Related Art Conventionally, there is a seat mounting device for a motorcycle or the like in which a seat is mounted on a vehicle body via a metal hinge so that the seat can be raised or folded. In this conventional seat mounting device, since the hinge is made of metal material, shocks from the road surface and engine vibrations while the vehicle is running are transmitted through the hinge, causing discomfort to the occupants. -1 The present invention has been made in view of the above circumstances, and an object of the present invention is to propose a seat mounting device that does not transmit vehicle body vibrations to the seat. The present invention is characterized in that the seat and the vehicle body are connected to the vehicle body so that the seat can be raised and folded through an elastically deformable synthetic resin plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a seat attachment device for a motorcycle or the like according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a schematic side view of the rear half of a motorcycle to which an embodiment of the present invention is applied.

In Figure 1, the main pipe lO as the vehicle body frame
A fuel tank 14 is provided at the upper end via a bracket 12, and this fuel tank 14 is further provided with a tongue piece 2, which will be described later.
4, a sea) 16 is attached so as to be able to rise and fall, and fuel can be supplied from a fuel filler port (not shown) provided on the upper surface of the fuel tank 14. First, the shape of the seat 16 will be explained according to FIG. 2. The seat 16 has a bottom plate 18 made of synthetic resin, a cushion material 20 made of urethane or the like located on the bottom plate 18, and a lower end portion of the seat 16 that is secured to the bottom plate 18. It consists of a vinyl cover 22 that covers the top from the sides. The bottom plate 18 is made of synthetic resin such as polypropylene, polyethylene, and soft vinyl chloride.

As shown in FIG. 3, a tongue piece 24 is formed to protrude straight from the bottom plate 18 at 5. As shown in FIG. The tongue piece 24 is integrally molded with the bottom plate 18, is made of synthetic resin, and is elastically deformable. This tongue piece 2
4 functions as a connecting member for raising and lowering the seat 16.

A bolt hole 26% 26 is formed in this tongue piece 24. A rubber damper 28% 28 (only one is shown in FIG. 2) for vibration isolation is attached to the bottom plate 18, and a rubber damper 30 with a suction cup is provided on the right side of the rubber damper 28 in FIG.

A bracket 34 having a U-shaped cross section is welded to the upper surface 32 of the fuel tank 14. A nut 36 is attached in advance to the back side of this bracket 34. A bolt 38 is inserted from above into the bolt holes 26 to 26 of the tongue piece 24, and this bolt 38 is screwed into the nut 36. From this K, the end of the tongue piece 24 is attached to the upper surface 32'':'' of the fuel tank 14. A recess 40 is formed in the upper surface 32° of the fuel tank 14.
A stand damper 30 with a suction cup is located at o, and the recess 40 functions to stop the sheet 16 from moving.

According to the embodiment described above, since the connecting portion is formed of the elastically deformable resin tongue piece 24, vibrations coming from the main frame 10 on the vehicle body side are absorbed by the tongue piece 24 and the vibrations from the sea) 16 are absorbed by the tongue piece 24. Furthermore, since the tongue piece 24 is integrally formed with the bottom plate 18, there is no need to attach the connecting member to the bottom plate 18 when constructing the connecting portion.

FIG. 4 shows the structure of another actual failure example related to the present invention,
The tongue piece 24 has a thinner wall thickness at a portion indicated by reference numeral 42 to form a bent portion, and the sheet 16 is therefore configured to be able to be raised and folded around the bent portion 42. A bent portion 42 having a thin wall thickness is formed on the tongue piece 24, and the position of the bent portion 42 is determined, so that the seat can be raised and lowered. Furthermore, the tongue piece 24 is bent at the bent portion 4.
Since the sheet is in a closed state when bent at 2, the tongue piece 24 also functions to stop the sheet 16 from moving.

In the embodiment shown in FIG. 2, the tongue piece 24 is formed integrally with the bottom plate 18, but 2. It is not limited to this, and may be configured separately. That is, as shown in FIG. 5, the tongue piece 46 is formed separately from the bottom plate 18. A bolt 48 is embedded in the bottom plate 18 during molding, and the upper end of the tongue piece 46 is attached to the bolt 48 by a hollow 50. Further, the lower end of the tongue piece 46 is connected to the nut 3 as in the embodiment shown in FIG.
6. It is fixed to the fuel tank 4 with bolts 38.

Even in the embodiment "F" shown in FIG. 5, the tongue piece 46 is made of elastically deformable synthetic resin, so it absorbs vibrations coming from the vehicle body and does not transmit them to the seat 16.

FIG. 6 shows an embodiment showing a modification of the detent of the seat 16. That is, instead of the four parts 40 shown in FIG. 2, a recess 52 is formed on the upper surface 32 of the fuel tank 14, and a protrusion 54)k is also formed on the bottom plate 18 of the seat 16. This protrusion 54 is located within the recess 1fj52 and has the function of preventing the sheet 16 from moving.

Although the above embodiment described a motorcycle,
The present invention can also be applied to motor tricycles.

As explained above, according to the seat mounting device for a motorcycle or the like according to the present invention, since the seat and the vehicle body are connected via the elastically deformable synthetic resin plate material, vibrations on the vehicle body side are absorbed by the synthetic resin plate material. The vibrations are absorbed and not transmitted to the seats, so there is no unpleasant vibration coming from the vehicle body to the occupants. ,
