(Prior Art) In a conventional scooter type vehicle, a slide mechanism is provided on an upper surface of a rear body to make a seat slidable. However, in this case, a large storage box is not arranged in the rear body. .

On the other hand, in some conventional scooter-type vehicles, a storage box is disposed in a rear body, and an upper opening of the storage box can be opened and closed by a seat rotatably configured by a hinge. In this case, there is no mechanism for sliding the sheet.

(Problems to be Solved by the Invention) As described above, in the conventional scooter-type vehicle, the storage box is arranged in the rear body under the seat, and there is no one in which the seat can slide. .

The present invention has been made in consideration of the above circumstances, and has as its object to provide a seat adjustment device for a scooter-type vehicle that can slide a seat while securing a storage box under the seat.

[Configuration of the invention]

(Means for Solving the Problems) According to the present invention, the space between the handle and the seat is deeply curved to form a step board portion, a storage box is arranged in the rear body below the seat, and the upper opening of the storage box is opened and closed. The front end of the inner cover is hinged to the rear body by a hinge, and a seat slide mechanism is provided between the inner cover and the seat so that the seat is slidable in the front-rear direction. The slide mechanism includes a pair of left and right rear slide mechanisms disposed on the rear side of the seat in front view left and right, and a pair of left and right rear slide mechanisms in front view near the hinge on the front side of the seat. A front slide mechanism provided at an intermediate portion, wherein the front slide mechanism locks the slide position of the seat. The seat lock mechanism is provided.

(Operation) Therefore, according to the seat adjusting device for the scooter type vehicle according to the present invention, the seat position is adjusted by operating the slide mechanism while the inner cover is closing the upper opening of the storage box, thereby adjusting the seat to the inner position. It is performed by sliding relative to the cover.

The sliding position of the seat is locked by the seat lock mechanism.

Also, when the rear end of the sheet is lifted upward, the rear end of the inner cover rotates about the hinge at the front end thereof and is simultaneously lifted upward, and the upper opening of the storage box is opened from the rear side. At the time of this opening, the seat slide mechanism is disposed between the inner cover and the seat, so that there is no obstruction when luggage enters and leaves the upper opening of the storage box.

The seat slide mechanism is provided with a pair of left and right rear slide mechanisms on the rear side of the seat, and a front slide mechanism is provided on the front side of the seat between the left and right rear slide mechanisms in front of the left and right sides. Since the three slide mechanisms are arranged in a triangular shape and the front slide mechanism is provided with a seat lock mechanism, the seat lock mechanism is not provided in each of the pair of left and right rear slide mechanisms. It is possible to prevent the sheet from being twisted at the time of locking.

As a result, the seat lock function of the seat lock mechanism can be stabilized, the cost can be reduced by reducing the number of seat lock mechanisms to one, and the operability of the seat lock mechanism is improved. Can be done.

In addition, since the seat lock mechanism is provided near the hinge at the front end of the inner cover on the front side of the seat together with the front slide mechanism, the weight on the rear side of the seat is lower than when these mechanisms are provided on the rear side of the seat. Since it becomes lighter, the operation force for lifting the seat and the rear end of the inner cover upward to open the upper opening of the storage box can be reduced by leverage.

 Next, the function and effect will be described.

As shown in FIG. 6, when the seat 5 is lifted, the inner cover 18 is simultaneously lifted because the inner cover 18 is connected to the seat 5 by the front slide mechanism 20 and the rear slide mechanism 21. Thereby, the opening 15 of the storage box 11 is opened, and luggage such as the helmet 14 can be put in and out of the storage box 11. In FIG. 6, the front slide mechanism 20, the seat lock mechanism 33, and the like are omitted.

Next, the seat 5 is pushed down, and the opening 15 of the storage box 11 is closed by the inner cover 18. In this state, the operating handle 32 of the slide lock rod 29 shown in FIG. 1 is rotated from the vertical position to the horizontal position, and the lock of the seat lock mechanism 33 is released. While holding the operation handle 32, the operation handle 32 is moved in the front-rear direction of the vehicle, and the seat 5 is slid with respect to the rear body 7.

(FIG. 6). For this reason, the appearance of the vehicle is not spoiled even when luggage is put in or out.

Further, since the inner cover 18 completely covers the opening 15 of the large storage box 11, the area is formed large, and the front slide mechanism 20 and the rear slide mechanism 21 are installed on the upper surface of the inner cover 18. The degree of freedom of the installation positions of the slide mechanisms 20 and 21 can be increased. In particular, since the interval between the two rear slide mechanisms 21 can be set large, the seat 5 does not rattle in the width direction of the vehicle, and the stability of the seat 5 can be improved. At the same time, since one front slide mechanism 20 is provided on the front side of the inner cover 18, the widths of the front ends of the inner cover 18 and the seat 5 can be reduced, and the rider's feet can be improved.

In the slide mechanism, one front slide mechanism 20 is provided at the front of the inner cover 18 and two rear slide mechanisms 21 are provided at the rear, so that one seat lock mechanism is provided for this one front slide mechanism 20. If 33 is installed, the slide of the seat can be locked stably. In other words, if the slide mechanism is only two rear slide mechanisms 21 arranged in parallel, twisting will occur unless the lock mechanism 33 is installed in each slide mechanism 21,
Since one front slide mechanism 20 is installed in addition to the two rear slide mechanisms 21 arranged in parallel, if one seat lock mechanism 33 is installed on this front slide mechanism 20, twisting does not occur. . As described above, according to this embodiment, the seat lock mechanism 33 can function stably, and the number of the seat lock mechanisms 33 can be reduced, so that the cost can be reduced.

Further, since the operating handle 32 of the slide lock rod 29 is provided in front of the seat 5 between the legs of the rider sitting on the seat 5, it is easy to apply force when moving the seat 5.

Moreover, since the operating handle 32 is in the vertical position shown in FIG. 1 by the urging force of the return spring 40 when the seat lock mechanism 33 is locked, it does not interfere with the rider's feet.

Further, since the operation handle 32 is located in front of the seat 5 and the operation direction of the operation handle 32 matches the slider direction of the front slide mechanism 20 and the rear slide mechanism 21, the operation handle 32 is operated when the operation handle 32 is operated. Slide lock rod 29 and front guide rail 27 of thrust mechanism 20
Further, no excessive force acts on the rear slide rail 25 and the rear guide rail 26 of the rear slide mechanism 21, and the operability is improved.

The seat slide mechanism includes a pair of left and right rear slide mechanisms 20 and 21 disposed on the rear side of the seat 5, and a pair of right and left rear slide mechanisms on the front side of the seat 5. The front slide mechanism 20
The three slide mechanisms 20, 21 are arranged in a triangular shape, and the front slide mechanism 20 is provided with a seat lock mechanism 33. Even when the lock mechanisms 33 are not provided, it is possible to prevent the seat 5 from being twisted when the seat is locked.

As a result, the seat lock function of the seat lock mechanism 33 can be stabilized, and the number of the seat lock mechanisms 33 can be reduced to one to reduce the cost. Performance can be improved.

Also, the seat lock mechanism 33 is connected to the front slide mechanism 20.
At the same time, since it is provided near the hinge 19 at the front end of the inner cover 18 on the front side of the seat 5, these mechanisms 3
Since the weight of the rear side of the seat 5 is lighter than the case where 3, 20 is provided at the rear part of the seat 5, the rear ends of the seat 5 and the inner cover 18 are turned upward to open the upper opening of the storage box 11. The operation force at the time of lifting can be reduced by leverage.
