Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat for a motorcycle, and more particularly to a seat for a motorcycle having a lumbar support capable of moving a passenger's seat in the vehicle longitudinal direction.

[0002]

2. Description of the Related Art A large motorcycle capable of two-seaters is usually provided with a driver's seat on which a driver sits and a passenger's seat on which a passenger sits. Known two-seat seats include tandem seats in which a passenger seat is mounted independently of a driver seat and double seats in which a driver seat and a passenger seat are integrally formed. .

However, in any of the above types,
Conventionally, it has not been possible to adjust the position of the seat according to the physique of the driver or the passenger, and it has not been possible to obtain a sufficiently comfortable ride.

[0004] In addition, conventionally, in order to ensure low back pain and fatigue during long-time driving and to ensure the safety of the riding position, conventionally, a seat for a motorcycle and a passenger seat have been used. There is known a seat having a configuration in which a lumbar support for giving pressure (holding feeling) to a driver's waist portion (lumbar portion) is provided between the seat and the driver.

The lumbar support is adapted to apply an optimum pressure to the driver's waist and obtain a more comfortable ride, so that the lumbar support can be adjusted according to the occupant's physique and height. It is desirable.

[0006]

Therefore, lumbar supports of each size are prepared as an option, and the occupant's physique,
There is a method to select according to height. However, there is a problem that it is necessary to cope with various sizes and the cost increases. In addition, there is a disadvantage that the lumbar support must be replaced when another driver gets on the vehicle.

Further, in a two-seat motorcycle, when the lumbar support is adjustable in the front-rear direction, there is a problem that a gap is opened between the driver's seat and the passenger's seat. .

In order to eliminate the gap, there has been a method in which a plurality of auxiliary cushions corresponding to the size of the gap are separately formed to fill the gap. However, also in this case, it is necessary to prepare auxiliary cushions of various sizes, and there is a problem that the cost increases.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat for a motorcycle in which the position of a passenger seat and the position of a lumbar support can be freely adjusted according to the physique and height of the driver. It is in.

[0010]

SUMMARY OF THE INVENTION According to the present invention, there is provided a motorcycle seat according to the present invention, wherein the motorcycle seat includes a driver seat and a passenger seat. Is a fixed rail made of a long member having a substantially U-shaped cross section having a slit formed outside the vehicle body,
A sliding rail made of a long member having a substantially T-shaped cross section slidable on the fixed rail, a plate connected to the sliding rail, and a seat portion mounted on the plate, As the sliding rail slides on the fixed rail,
This is solved by the fact that the passenger seat is movable in the vehicle longitudinal direction.

As described above, the seat of the motorcycle according to the present invention is configured such that the seat portion on the plate is movable in the longitudinal direction of the vehicle body by the sliding rail sliding on the fixed rail. The position of the passenger seat can be adjusted according to the physique of the driver or the passenger.

Further, since the lumbar support is provided integrally with the seat portion, it is possible to adjust the lumbar support to a position most suitable for the driver by moving the passenger seat. And even if the lumbar support is moved to the driver side,
Since there is no gap between the driver's seat and the passenger's seat, the appearance does not deteriorate and the passenger's riding comfort can be kept good. .

Further, since the sliding rail is driven by an electric driving means, the driver simply presses a switch for turning on electricity to the driving means while riding on the motorcycle. It becomes possible to move the passenger seat and adjust the position of the lumbar support.

[0014]
