Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved support structure for an integral seat that is mounted and supported on a seat rail that constitutes a part of the body of a motorcycle.

Conventionally, this type of seat is attached to a single seat rail by a hinge at the lower part of one side, and is rotatable to the side of the vehicle body using the hinge attachment part as a base, so that the seat can be rotated. A part of the numerous support members made of elastic materials such as rubber attached to the underside of the seat are supported by the seat rail, and the remaining support members attached to the rear of the underside of the seat are supported by the brackets attached to the seat rail. By supporting it, it is adapted to be mounted and supported on the seat rail.

An object of the present invention is to make this type of seat support structure lightweight and simple, thereby improving the assemblability of a vehicle body and reducing costs.One embodiment of the present invention will be described below with reference to the drawings.

The drawings show a part of a motorcycle implementing the support structure of the present invention. This motorcycle has a pair of left and right seat rails 10 that constitute a part of the vehicle body,
10, a rear funder 20 with mounting parts on both front sides fixed to the rear ends of these seat rails 10, 10 via brackets 11, 11 and surrounding the upper rear part of the rear wheel; Fit and fix the front end side of the seat pillar tube 1.
a mudguard 30 that is secured to and attached to the seat rails 10 and 10 and surrounds the upper front part of the rear wheel;
A front and rear integral seat 40 is rotatably attached to one side of the vehicle via a hinge (not shown). At the front of the rear fender 20, there are brackets 11 at the rear ends of both seat rails 10, 10,
A slightly elevated flat seat support portion 20a is formed above between the mounting portions on both sides fixed to the seat support portion 11.

Therefore, the bottom plate 41 constituting the seat 40 has seat rails 1 at the front and approximately central portions thereof.
Four support members 42 to 43 made of an elastic material such as rubber are protruded at the portions corresponding to 0 and 10, and the rear portion of the bottom plate 41 corresponds to the flat seat support portion 20a at the front of the rear fender 20. Two supporting members 43, 43 made of an elastic material such as rubber are provided protrudingly at the portion. An integrated sheet 4 configured in this way
0, the seat 40 is rotated to the side of the vehicle body using a hinge attachment portion (not shown) as a base, and the seat rail 1
When placed on the seat rail 10,1
0 supports the front and substantially central portions of the seat 40 via support members 42 to 42 attached to the bottom plate 41, and also supports the seat support portion 20 of the rear fender 20.
a supports the rear part of the seat 40 via support members 43, 43 attached to the bottom plate 41. Therefore, the seat 40 is securely mounted and supported by the seat rails 10, 10 and the rear fender 20 without requiring any special bracket.

In addition, in this embodiment, the mat guard 30
At approximately the center of the upper surface, a storage case 50 for storing an igniter and other electrical components is connected to elastic members 51 to 51.
It is fastened with bolts 52-52 via.
This mat guard 20 is made of synthetic resin, and the storage case 50 can be easily fastened with bolts 52 to 52 without welding mounting members such as brackets, and the resin itself has an excellent vibration-proofing effect. Therefore, it is suitable as an attachment site for the storage case 50 for electrical components that are susceptible to vibration. In addition, when the mudguard 30 is running, the upper surface of the mudguard 30 comes into contact with the airflow flowing through the vehicle body, and the lower surface of the mudguard 30 comes into contact with the airflow generated by the rotation of the wheels. is effectively cooled.

It should be noted that the present invention can be carried out by appropriately modifying the above embodiments for various motorcycles in which an integral seat is mounted and supported on a pair of left and right seat rails that constitute a part of the vehicle body. be.

In summary, in the present invention, as is clear from the above embodiments, in a motorcycle in which an integral seat is mounted and supported on a pair of left and right seat rails that constitute a part of a vehicle body, the rear end of the seat rails is provided. The mounting portions on both sides of the rear fender are fixed to the rear fender, and a seat support portion is formed on the rear fender by being located above between the mounting portions on both sides, and the front and substantially central portions of the seat are fixed to the seat rails. The structural feature lies in the fact that the rear part of the seat is supported by the seat support part, which eliminates the need to provide a special bracket on the seat rail to support the rear part of the seat. First, the support structure of this type of seat can be simplified, improving the ease of assembling the vehicle body, and since the integral seat is supported on the seat rail at the front and approximately the center, the rear fender that supports the rear part of the seat can be used easily. In addition to reducing the load applied to the seat support part, the seat support part is located above the mounting parts on both sides and is formed in the rear fender, improving its strength and requiring only a small amount of reinforcement of the rear fender to support the seat. Therefore, it is possible to reduce the weight and cost of the seat support structure.
