FIG. 1 schematically shows a motorcycle with a tandem seat according to this embodiment. In the motorcycle 1, a low and wide step 4 is formed between a seat 2 and a steering wheel 3, and a step 4 is formed. Is a large scooter type capable of long-distance touring, in which the driver sits on the seat 2 and drives the seat 2. The seat 2 has a front seat 21 on which a driver sits and a rear seat on which a passenger sits. Sheet 22
And a tandem seat consisting of:

The tandem seat 2 is provided such that a seating surface 21a of the front seat 21 is lower than a seating surface of the rear seat 22, and a backrest 21b is integrally formed at a rear portion of the front seat 21. Backrest 21b
The front of the backrest 21 is formed in a concave shape so as to conform to the curvature of the waist of the driver and surround the waist from behind.
The upper portion b is formed so as to protrude further above the seating surface of the rear seat 22.

FIG. 2 shows a normal state of the tandem seat 2. The front seat 21 and the rear seat 22 are formed separately in a divided state.
The rear seat 22 is rotatably fixed to the frame 11 of the vehicle body at the front end thereof by the pivoting portion 5, and the rear seat 22 is pivotally fixed to the frame 12 of the vehicle body by the pivoting portion 6 at the rear end thereof. ing.

A luggage storage box 15 whose upper part is open is disposed below the rear seat 22. The opening of the luggage storage box 15 is formed by the backrest 21b of the front seat 21 from below the seating surface of the rear seat 22. extend to the lower side of, so that it can cover the entire opening of the luggage box 15, in this embodiment, the rear sheet 22
However, a cover 24 is integrally provided in front of the seat body 23.

As shown in FIG. 3, such a tandem seat 2 rotates the front seat 21 so as to rise forward around the pivot portion 5, and connects the rear seat 22 to the pivot portion 6.
, So that the opening of the luggage storage box 15 is opened, and the front seat 21 and the rear seat 22 return to their original states from the respective standing states. Thus, the opening of the luggage storage box 15 is closed.

In the present embodiment, the front seat 21 is installed so as to be adjustable in the front-rear direction with respect to the pivot portion 5 to the vehicle body, and is generated when the front seat 21 is slid forward. The gap between the rear seat 22 and the seat body 23 is the seat body 2 of the rear seat 22.
3 is covered by a cover part 24 integrally attached to the front of the cover 3.

As shown in FIGS. 4 and 6, the front end of the seat frame 31 is rotatably fixed to the pivot portion 5, as shown in FIGS. A bottom plate 32 of the front seat 21 is slidably attached in the front-rear direction via an attachment 33, and an adjustment member 34 provided with a plurality of engagement holes 35 in the front-rear direction is fixed to the seat frame 31. A locking member 37 provided with an engagement hole 36 corresponding to the engagement hole 35 of the adjustment member 34 is fixed to the bottom plate 32 of the seat.
In the front seat 21, the pin 3 is inserted into the engagement hole 36 of the locking member 37.
An operation member 39 which can be operated to be able to freely insert and remove 8 is provided.

According to such a structure, the front seat 21
Is slid to an appropriate position with respect to the seat frame 31, at which position one of the engaging holes 35 of the adjusting member 34 and the engaging hole 36 of the locking member 37 are aligned, and the operating member 39 is operated to engage the engaging hole. By penetrating the pin 38 into the engagement hole 36 and the engagement hole 36, the position of the front seat 21 with respect to the seat frame 31 can be fixed, and the front seat 21 can be positioned in the front-rear direction. By removing the pin 38 from the engagement hole 35 and the engagement hole 36, the above-described operation is repeated, whereby the front seat 2
1 can be readjusted, so that the front seat 21 can be adjusted according to the riding position of the driver without changing the arrangement of the entire tandem seat 2.
Can be easily changed.

As shown in FIGS. 5 and 6, a support frame 42 extending downward and forward from the seat body 23 is provided on the lower surface of the bottom plate 41 of the rear seat. A lower cover 43 that covers the entire lower side of the support frame 42 from the rear of the seat bottom plate 41 is fixed, and the support frame 42 is superimposed on the lower cover 43 above the front part of the lower cover 43. The cover part 24 is covered so as to cover from above.
Is attached.

Referring to FIG . 6, the rear seat 22
The pivoting part 6, the lower cover 43, and a front seat described later.
21 are shown in a state where the engagement pins 40 are omitted.
However, the lower cover 43 has substantially the same size and shape as the opening of the luggage storage box 15, and a seal member 48 is provided at a peripheral edge thereof.
, The opening of the luggage storage box 15 is closed.

By providing such a cover portion 24 and the lower cover 43, even if the opening of the luggage storage box 15 disposed below the rear seat 22 is made large, it can be sufficiently covered. Also,
Even if the front seat 21 is slid forward to increase the gap between the rear seat 22 and the seat body 23, the opening of the luggage storage box 15 is not exposed.

Further, at the rear end of the seat frame 31 of the front seat 21, an engagement pin 40 which engages with a lock device (not shown) installed on the lower surface of the seat mounting bracket 13 provided on the vehicle body frame. Is provided at the front end of the support frame 42 of the rear seat 22.
4, a cushion member 45 is attached to the lower surface of the mounting plate 44, and a notch 46 through which the engaging pin 40 is inserted as shown in FIG.
Are formed.

Thus, when the front seat 21 and the rear seat 22 can be seated, the mounting plate 44 fixed to the rear seat 22 by the support frame 42 is moved through the cushion member 45 to the seat mounting bracket. 13
The seat frame 31 of the front seat 21 is placed thereon, and the engaging pin 40 at the rear end of the seat frame 31 is locked to the sheet mounting bracket 13 through the cutout 46 of the mounting plate 44. Is done.

For this reason, the mounting plate 44 fixed in front of the rear sheet 22 is pressed onto the sheet mounting bracket 13 by the rear portion of the front sheet 21, and the engagement pins 4
0 means that the front seat 21 and the rear seat 22 are not immovable in the horizontal direction, and are not shifted in the horizontal direction.

Further, since the rear seat 22 is pressed by the front seat 21 locked to the vehicle body, it is not necessary to provide a separate locking device for the rear seat 22.

Although the embodiment of the motorcycle with a tandem seat according to the present invention has been described above, the present invention is not limited to this. For example, the slide adjusting structure of the front seat 21 is omitted. <br/> like are also Ru possible der, it goes without saying as it can be designed and changed.
