Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat device for a passenger in a motorcycle or other two-wheeled vehicle.

Conventionally, as this type of device, a passenger car seat is provided on the upper surface of a vehicle body frame having front and rear wheels and an engine located in the middle thereof, with a shaft at the end thereof, so that the seat can be opened upwardly, and the seat can be moved upwardly as necessary. There are known types of seats that can be opened to inspect the parts inside, but in this case, the seat must be able to open easily and not be accidentally closed in the open position. is preferred.

The purpose of the present invention is to obtain a device that meets such requirements, and includes front and rear wheels 1, 1,
A seat 4 for a passenger is provided on the upper surface of a vehicle body frame 3 having an engine 2 at an intermediate portion thereof, and the front end portion thereof is freely opened upwards with a shaft 5 at a rear end portion as an axis. 3, and the rear cowling 8 is integrally connected to the seat 4, so that the seat 4 and the rear cowling are connected between the lower surface of the seat 4 and the vehicle body frame 3. A resilient member 6, which is a gas damper, is interposed between the spring and the gas damper.

In the illustrated example, the body frame 3 is provided with a front cowling 7 at the front and a rear cowling 8 at the rear. Cowling 8 was made to open upwards accordingly. In the drawing, 9 indicates a fuel tank in front of the seat 4, and 10 indicates a supercharger in front of the engine 2.
The elastic member 6 consists of a pair of male and female rods 6a and 6b that are fitted into each other, and is of a type that extends to a predetermined length due to the volume expansion of the air compressed inside as the elastic member 6 contracts. At both ends of each bracket 1 on the seat 4 side and the frame 3 side
1 and 11 with respective pins 12 and 12. The seat 4 is pivotally supported by a bracket 14 on the frame 3 side by a shaft 5 at the tip of an arm 13 extending rearward, but in the illustrated example, the shaft 5 is supported by a longitudinal guide groove 15 formed in the bracket 14. ,15
When opening the seat 4, the shaft 5 and the guide groove 1 are engaged by pressing the seat 4 backward once.
5 and 15, and then opened upward at that position. Further, when the seat 4 is next closed and moved forward, the pin 16 on the side thereof will engage with the U-shaped groove piece 17 on the frame 3 side and be fixed in that position. 18 in the drawing is the sheet 4
Shows the rear grip around the periphery.

To explain the operation, the seat 4 is opened upward along with the rear cowling 8 about the rear shaft 5, and at this time, the elastic member 6 opens the seat 4 by volume expansion of the air inside. The resilient member 6 helps the opening operation of the sheet 4 by repelling it to the side, thus making the operation easier when opening it by hand.Then, the resilient member 6 extends to a predetermined length to hold the sheet 4 in its open position. This prevents it from being inadvertently closed, and the sheet 4 can then compress the member 6 and close it in preparation for the next operation.

In this way, according to the present invention, the shaft 5 at the rear end of the passenger seat 4 is engaged with the longitudinal guide groove 15 provided in the vehicle body frame 3. Since the seat 4 can be moved to the end and opened upward, a large work space can be obtained.A rear cowling 8 is integrally connected to the seat 4, and a rear cowling 8 is integrally connected to the seat 4 to provide a space between the lower surface of the seat 4 and the vehicle body frame 3. Since a springing member 6 made of a gas damper is interposed to spring both the seat 4 and the rear cowling 8 toward the open side, the springing member 6 can be easily attached, and when the seat 4 is opened. Since the rear cowling 8 also opens upward, there is an effect that workability such as inspecting the members stored in the space surrounded by the seat 4 and the rear cowling 8 is greatly facilitated.
