In such a structure, since the second seat is not allowed to rotate independently, the second seat is rotated with the luggage placed on the upper surface of the first seat to open a part of the storage portion. This is not possible and is inconvenient. Further, even when the first and second sheets are erected in a folded state, the second sheet remains in the opening portion of the storage portion, and thus the storage portion cannot be fully opened. Further, the installation of the rails not only complicates the structure of the seat device, but also causes inconveniences such as narrowing the opening of the storage section and increasing the size of the vehicle body.

An object of the present invention is to provide an occupant seat device for a motorcycle, which can eliminate all of the inconveniences and inconveniences of the conventional device.

Between the two sheets, there is provided a regulation means for regulating the rotation of the second sheet toward the storage portion side with respect to the first sheet when the first sheet is rotated to the open position and opening the entire storage portion. That is the first feature.

The first sheet and the second sheet respectively correspond to a front sheet 13 and a rear sheet 14 of the present invention described later.

According to the first feature, the second sheet can be independently rotated upward to open only the other half of the storage section. Therefore, at this time, it is possible and convenient to place a parcel on the upper surface of the first seat that remains in the closed position. Further, even if the rear seat is rotated upward together with the front seat and the opening operation force is released from the second seat at the open position of the first seat, the downward rotation of the second seat due to its own weight is restricted by the restricting means. Therefore, the entire storage unit is
In addition, the second seat can be in a fully opened state without any hindrance. Moreover, since a rail for guiding the second seat, which is required in the related art, is not required around the storage portion, it is possible to avoid the storage portion becoming narrow and the vehicle body becoming large.

In addition to the first feature of the present invention, a telescopic damper for urging the first seat toward the open position is interposed between the vehicle body and the first seat. The second feature is that the first sheet is arranged so that it contracts and falls when it is in the closed position, and it expands and stands up when the first sheet rotates to the open position.

According to this second feature, the opening operation of both the first and second seats can be carried out lightly with the aid of the urging force of the damper, and both seats can be moved to the open position with the urging force of the damper. Can be held. Moreover, the damper arranged so that it contracts and falls when the front seat occupies the closed position and extends and stands up as the front seat moves toward the open position, even if the damper is made relatively short, It is possible to follow the opening and closing operation of.

Further, in the present invention, in addition to the first or second feature, a pair of left and right hooks are provided at the outer end portion of the second seat,
A third feature is that the locking pin with which these hooks are engaged to hold the second seat in the closed position is formed of a part of a bolt for fixing the luggage box forming at least a part of the storage part to the vehicle body. According to the third feature described above, a part of the bolt for fixing the luggage box to the vehicle body also serves as the locking pin, which can contribute to simplification of the structure and improvement of the assembling property.

An endless annular seal member 36 is attached to the bottom plate 14a of the rear seat 14 corresponding to the peripheral edge of the opening of the luggage box 6, and when the rear seat 14 is closed, the seal member 36 is closed. The inside of the luggage box 6 is designed to be waterproof and dustproof in close contact with the upper surface of the peripheral portion of the opening.

Next, the operation of this embodiment will be described.

As shown in FIG. 2, the hook 32 of the rear seat 14 is engaged with the locking pin 35, and then the front seat 13 is engaged.
By engaging the locking ring 20 of 1 with the latch 21, both seats 13 and 14 are held in the closed state. Therefore, the operator can sit on the front seat 13 and the passenger on the rear seat 14.

When the latch 21 is released to release the locking ring 20 and the rear end of the front seat 13 is slightly lifted as shown in FIG.
Is moved forward, its hook 32 is disengaged from the locking pin 35. Therefore, since the rear seat 14 is free, the front seat 13 is left in the substantially closed position C as shown in FIG. 6, and only the rear seat 14 is rotated upward to open the luggage box 6 and the helmet 5 or the like. You can take your luggage in and out. Moreover, since the upper surface of the front seat 13 remaining in the substantially closed position C is kept substantially horizontal, it is possible to place gloves or other small luggage 37 thereon, which is convenient.

Next, when the parcel 37 is removed from the front seat 13 and the rear seat 14 is rotated upward together with the front seat 13, the front seat 13 is opened by the extension force of the damper 22. It can be swung up to O.

In the state where the front seat 13 reaches the open position O, even if the upward turning operation force for the rear seat 14 is released, the front seat 13 is not supported by the damper 22 as shown in FIG.
Is held in the open position O, that is, the standing position with the extension force of. At that time, when the rear seat 14 slightly rotates downward due to its own weight, the restriction projection 31 of the bottom plate 14a of the rear seat 14 comes into contact with the bottom plate 13a of the front seat 13,
Further downward rotation of the rear seat 14 is prevented. Thus, since the front half of the storage part 2 and the luggage box 6 are in the fully opened state where the seats 13 and 14 do not interfere with each other, not only the fuel tank 3 is refueled but also the luggage box 6 is loaded. Can be easily put in and taken out. Moreover, since a rail for guiding the rear seat 14 unlike the conventional case is not required around the front half of the storage part 2 and the luggage box 6, the storage part 2 becomes narrow and the vehicle body 1 becomes large. Nor.

In order to return the front and rear seats 13 and 14 to the closed position, an operation opposite to the above may be performed.

By the way, the damper 22 is arranged so that it contracts and falls when the front seat 13 occupies the closed position C as described above, and extends and stands up as the front seat 13 moves toward the open position O. Therefore, it is possible to follow the opening / closing operation of the front seat 13 while making it relatively short.

The locking pin 35 with which the hook 32 is engaged in order to hold the rear seat 14 in the closed position is composed of the head of the bolt 10 for fixing the luggage box 6 to the rear bracket 8. The head also serves as the locking pin 35, which can contribute to simplification of the structure and improvement of the assemblability.

The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention. For example, although the occupant seat 12 is configured to open front in the above embodiment, it may be configured to open rear, and in this case, the rear end of the rear seat 14 can be pivoted to the vehicle body 1 by the hinge shaft. And the front end of the front seat 13 is locked to the locking pin of the vehicle body. Further, in the first half of the storage part 2, a battery or other auxiliary equipment may be stored instead of the fuel tank 3.

In an occupant seat device for a motorcycle, which is attached to a vehicle body such that the storage part can be opened and closed, a first seat is provided between a closed position where one half of the storage part is closed and an open position where the same half part is opened. The second seat is pivotally supported on the vehicle body so as to be rotatable, and the second seat is connected to the first seat so that the other half of the storage portion can be opened and closed by independent rotation of the second seat. A regulating means is provided between the sheets to regulate the rotation of the second sheet toward the storage portion side with respect to the first sheet when the first sheet is rotated to the open position to open the entire storage portion. Therefore, by rotating the second seat independently upward, only the other half of the storage section It can be release. Therefore,
At that time, it is convenient because it is possible to place a parcel on the upper surface of the first seat that remains in the closed position. Further, even if the rear seat is rotated upward together with the front seat and the opening operation force is released from the second seat at the open position of the first seat, the downward rotation of the second seat due to its own weight is restricted by the restricting means. Therefore, the entire one half and the other half of the storage section can be fully opened without being disturbed by the first and second seats. Moreover, since a rail for guiding the second seat, which is required in the related art, is not required around the storage portion, it is possible to avoid the storage portion becoming narrow and the vehicle body becoming large.

According to the second feature of the present invention, in addition to the first feature, a telescopic damper for biasing the first seat toward the open position is interposed between the vehicle body and the first seat. Since the damper is arranged so that it contracts and falls when the first seat is in the closed position and extends and stands up when the first seat rotates to the open position, both the first and second seats are arranged. The opening operation of can be performed lightly by using the urging force of the damper, and both seats can be held in the open position by the urging force of the damper. Moreover, the damper arranged so that it contracts and falls when the front seat occupies the closed position and extends and stands up as the front seat moves toward the open position, even if the damper is made relatively short, It is possible to follow the opening and closing operation of.

According to a third aspect of the present invention, the first
Alternatively, in addition to the second feature, a pair of left and right hooks is provided at the outer end portion of the second sheet, and a locking pin with which the hooks engage to hold the second sheet in the closed position is provided in at least one of the storage portions. Since the luggage box that constitutes the part is composed of a part of the bolts that secure the vehicle body to the vehicle body, part of the bolts that secure the luggage box to the vehicle body also serves as a locking pin.
This can contribute to simplification of the structure and improvement of the assemblability.
