DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat device provided in a scooter type vehicle, and more particularly to a seat device for a scooter type vehicle having divided front and rear seats.

[0002]

2. Description of the Related Art As is well known, in a scooter type vehicle, a seat is provided behind a handle supported by a front portion of a vehicle body via a wide leg space, and a trunk portion is formed below the seat. This is where the helmet can be stored. Among such scooter-type vehicles, large vehicles are provided with large seats having a large area in the front-rear direction in order to enable two-seaters (see FIGS. 5 and 6). ). Usually, such a large seat A is provided with a backrest A1 as shown in FIGS. 5 and 6 in order to secure a driver's riding posture, reduce fatigue, and the like. Has been proposed that can adjust the fixed position of the front and rear according to the physique of the rider.

FIGS. 7 and 8 show examples of seats in which the fixed position of the backrest can be adjusted in the front-rear direction. This seat B has two front and rear seats B1 and B2 arranged in two stages, an upper rear seat B2 is provided on the body frame F so as to be movable in the front-rear direction, and a front end B2a is provided at the backrest. It has become.

[0004]

However, the above-mentioned conventional sheet has the following problems. That is, in the seats shown in FIGS. 5 and 6, since the backrest A1 is held on the seat A, the seat A1 can be attached to the seat support portion C by a hinge D or the like so as to be openable and closable, It is possible to form a trunk T in the seat support portion C using the seat A as a lid, but usually, the seat A provided with the backrest A1 is provided.
Is large, and the hinge portion D and the seat support portion C are required to have high rigidity in order to support and connect them. However, since the seat supporting portion D is generally made of resin, sufficient rigidity and strength cannot be obtained for the hinge portion D.
There is also a problem that sufficient stability cannot be obtained for the fixed sheet A.

[0005] For this reason, in order to obtain a sufficient strength for the hinge portion D, it is necessary to form the seat supporting portion C from a material having high rigidity and high strength, resulting in a significant increase in cost. It is also conceivable to increase the strength of the hinge portion D by increasing the width of the hinge portion D. However, when the width of the hinge portion D is increased, the seat width also needs to be increased accordingly. A new problem arises in that the rider's footwear is impaired.

On the other hand, in the split type seat shown in FIGS. 7 and 8, the rear seat B2 slidably provided on the vehicle body frame F partially overlaps the upper surface of the front seat B1. Therefore, it is not possible to adopt a configuration in which the front seat B1 located under the seat B1 is opened and closed in the vertical direction, and as a result, it cannot be applied to a vehicle in which the trunk T is formed below the seat B1.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides sufficient strength to the hinge portion without increasing the width of the seat and good stability to the fixed seat. It is an object of the present invention to provide a scooter-type vehicle seat device capable of performing the above-described operation.

[0008]

The present invention has the following arrangement to solve the above-mentioned problems. That is, in a scooter-type vehicle provided with a seat that opens and closes an opening thereof above a trunk portion provided via a leg space behind a handlebar, the seat is a front seat,
The front seat and the rear seat are partially overlapped on the upper surface of the front seat, and the front seat and the rear seat are supported by the integrated seat frame, and the fixed position of the rear seat to the frame can be adjusted in the front-rear direction. And a hinge portion for rotatably connecting a front end portion of the seat frame to a vehicle body frame located at a front portion of the trunk portion and the seat frame, and an opening of the trunk portion can be opened and closed by the seat. It is made to cover.

In the above invention, since the front seat and the rear seat are supported by the integrated seat frame, the entire seat can be opened and closed together with the seat frame, and the trunk is provided below as a lid. The luggage can be taken in and out of the department. Further, since the seat is supported by the seat frame, the entire seat can be configured with high rigidity even for a large seat. For this reason, good stability can be obtained for the seat even when the seat is closed, and the dimensional control of the seat is also facilitated, and the sealing performance with the trunk opening when the seat is closed is easily enhanced. Furthermore, since the hinge portion is provided on the frame, sufficient rigidity can be obtained without increasing the width of the hinge portion, and there is no need to increase the vehicle width. Further, if the fixed position of the rear seat is adjusted according to the physique of the rider, good riding performance can be obtained.

FIG. 1 is an external side view showing a scooter type vehicle to which an embodiment of the present invention is applied, FIG. 2 is a bottom view showing an embodiment of the present invention, and FIGS. 3 and 4 are illustrations showing use states of those shown in FIG. It is a side view.

Referring to FIG. 1, a scooter type vehicle 1 shown here is a large scooter capable of two-seaters, and a head provided at the front end of an underbone type body frame 1A is provided at the front of the body. The handle 2 and the front fork 3 are rotatably supported around a steering stem by a pipe or the like, and a wide leg shield 4 is formed to cover the legs of the front rider.
A seat support 5 is formed behind the handle 2 via a wide leg space S. A trunk 6 for accommodating a helmet or the like is formed in the seat support portion 5, and an opening of the trunk 6 is opened and closed by a seat device 10 described below as a lid. .

FIGS. 2 to 4 are views showing the seat device 10. The seat device shown in FIG. 2 includes a seat 11 composed of a front seat 12 and a rear seat 13 formed separately, And a seat frame 14 supported from the back side. The seat frame 14 is formed by connecting a pair of left and right rod-shaped members 15 and 16 with a predetermined facing distance by a bridging member 17, and has an integrated structure as a whole. Further, each of the rod-like members 15, 16 has a bent side surface by forming steps 15b, 16b between the front support portions 15a, 16a and the rear support portions 15c, 16c. . In addition, each bar-shaped member 15,
The front end portions 15A, 16A of the frame 16 are formed such that their opposing intervals are narrower than the other portions, and the support shaft (hinge portion) 14a inserted therethrough allows the frame located at the front end portion of the seat support portion 5 to be positioned. 1A is rotatably supported.

The front seat 13A and the rear seat 13 are made of a cushioning material such as urethane foam, and the bottom surface of the front seat 12 is firmly fixed to the front support portion 13a of the seat frame 13. ing. The rear seat 13 is supported by a predetermined slide mechanism so as to be adjustable in a fixed position in the front-rear direction with respect to the rear support portion, and its movement is performed along the upper surface of the front seat 12, and a part of the rear seat 13 is moved forward. The upper surface of the sheet 12 is superposed. In addition, as a slide mechanism of the rear seat, a fitting portion that is movably fitted to the seat frame,
Various configurations are applicable, such as providing a locking member for locking the fitting portion to the seat frame. In FIG. 2, reference numeral 13a denotes a handle to be gripped when adjusting the fixed position of the rear seat 13.

In the scooter type vehicle provided with the seat device having the above-described configuration, the front seat 12 and the rear seat 1 are provided.
The front end 13A of the rear seat 13 serves as a backrest to support the lower part of the back of the front rider, thereby securing the posture of the front rider and reducing fatigue. It has become. In addition, since the physique of the rider varies, the appropriate distance from the backrest (front end of the rear seat) to the leg shield also needs to be appropriately adjusted according to the physique of the rider. This can be performed by moving the camera in the front-rear direction. Also, after getting off the vehicle, the seat lock is released with a key, and the seat 11 is rotated upward from the opening of the seat support portion 5, so that the trunk 6 is in an open state, and the helmet can be stored here. If the opening is closed again with the seat 11 and locked with a key, the seat 11 functions as a lid of the trunk 6 and theft or the like can be prevented.

When the seat 11 is opened and closed, the front seat 12 and the rear seat 13 are both held by the seat frame 14. Therefore, by rotating the seat frame 14, both the seats 12, 13 rotate.
And, due to the presence of the seat frame 14, the seat 11 can have excellent rigidity and strength, and the dimensional control of the seat can be performed extremely easily. For this reason,
The sealing performance of the seat 11 with respect to the opening of the trunk 6 can be improved without variation.

Since the support shaft 14a, which is a hinge portion, is provided on the frame 1A having high rigidity, in this embodiment, the opposing interval between the rod-shaped members 15, 16 through which the support shaft 14a is inserted is relatively narrow. , The connection state of the seat 11 can be maintained with sufficient rigidity and strength. Therefore, compared with the conventional case where the sheet 11 is held only by the sheet supporting portion made of resin,
The fixed state of the seat 11 at the time of closing is enhanced, and good stability can be obtained even for a large seat for two-seater. Further, since a sufficient strength can be obtained even with the hinge 14a having a small width, it is not necessary to increase the width of the seat for the hinge 14a, and the seating performance of the seat is not impaired.

In the above embodiment, the seat frame 14 is constituted by the two rod-like members 15, 16 and the bridging member 17, but the seat frame 1
4 is composed of three or more rod-shaped members,
It is also possible to use a single rod-shaped member bent in a letter shape or an annular shape.
The shape of 4 is not particularly limited to the above embodiment.

[0018]

As described above, according to the present invention, the front seat and the rear seat are supported by the integrated seat frame, and the fixed position of the rear seat can be moved in the front-rear direction with respect to the seat frame. Therefore, the entire seat can be opened and closed together with the seat frame, and the luggage can be taken in and out of a trunk provided below using the seat as a lid. In addition, even if the sheet is large, the entire sheet can be configured to have high rigidity, so that the sheet can have good stability even when the sheet is closed, and dimensional control of the sheet can be easily performed. In this case, the sealing performance with the trunk opening can be easily enhanced.

Further, since the seat frame having high rigidity and the vehicle body frame are connected by the hinge portion,
