Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a driver's seat device for a vehicle in which a straddle-type driver's seat, which is long in the front-rear direction, is provided with a seat switch.

(Background of the Invention) Automatic 2.3.
Some four-wheeled vehicles, snowmobiles, and the like are equipped with a seat switch on the driver's seat to detect when the driver is seated.

This seat switch is used, for example, to start the engine with the driver properly seated.

In this case, it is necessary to electrically connect the driver's seat and the vehicle body side with the wiring cord of the seat switch.

However, since auxiliary equipment such as an air purifier and batteries are normally housed below the driver's seat, the driver's seat must be removable for maintenance and inspection of these devices. For this reason, there has been a problem in that the wiring cord of the seat switch becomes an obstacle when attaching and detaching the driver's seat and when servicing and inspecting auxiliary equipment.

(Object of the Invention) The present invention has been made in view of the above circumstances, and is intended to provide a vehicle in which the wiring cord of the seat switch does not become an obstacle during maintenance and inspection of auxiliary equipment stored below the driver's seat. The purpose is to provide a driver seat device.

(Structure of the Invention) According to the present invention, this object is provided in a vehicle that is provided with a straddle-type driver's seat that is long in the front-rear direction on the upper part of the vehicle body, and that the driver's seat is provided with a seat switch that detects whether the driver is seated.
This is achieved by a driver's seat device δ for a vehicle, wherein the seat can be opened and closed using either the front or rear end as a fulcrum, and the wiring cord of the seat switch is connected to the vehicle body through the vicinity of the fulcrum.

(Example) Fig. 1 is a side sectional view of the vicinity of the straddle-type driver seat showing an embodiment of the present invention, Fig. 2 is a side view of a four-wheeled vehicle for traveling on rough terrain to which this is applied, and Fig. 3 is FIG. 2 is a sectional view taken along the line mm in FIG. 1. FIG.

In FIG. 2, the reference numeral 10 denotes a vehicle body frame, which includes a pair of large-diameter left and right lower tubes 12.12, a left and right pair of small-diameter upper tubes 14.14, and appropriate cross tubes, vertical tubes, etc. that connect these. Equipped with. The front part of the lower tube 12 is bent upward in a substantially fishhook shape, the lower front parts thereof are connected to each other by a bracket 16 in close proximity to each other, and the upper front parts are expanded to each other and are joined by a cross tube 18. The lower tube 12 is connected behind the cross tube 18 by a pair of left and right vertical tubes 19 (only one of which is shown). A pair of left and right front wheels 20 are held at the front of the lower tube 12 so as to be movable up and down by a known strut-type independent suspension system. Reference numeral 22 designates an A-shaped lower arm of this suspension system, and the inner ends, which are the two bases of the A-shaped lower arm, are pivotally attached to the front lower part of the lower frame 12 so as to be swingable. A cylindrical shock absorber 26 is interposed between the swinging end of the A-shaped top of the lower arm 22 and a bracket 24 fixed to the front upper part of the lower tube 12. A bracket (not shown) is secured. A knuckle for holding the front wheel 20 is attached to the knuckle bracket so as to be rotatable left and right. 28 is a steering axis;
Its lower end is supported by the bracket 16, and its upper part is supported by an arcuate cross member 30 which extends over the upper tube 14.14. 32 is a steering bar handle fixed to the upper end of this steering shaft 28.

34 is a rear axle, which is held by a pair of left and right lower arms 36 and one A-type upper arm 38 so as to be vertically movable. 40 is a rear wheel axle inserted through this rear axle 34;
Reference numeral 2 denotes a pair of left and right rear wheels attached to both ends of this rear wheel shaft 40. Further, 44 is a cylindrical shock absorber that supports the rear axle 34. The front wheels 20 and the rear wheels 42 are equipped with wide ultra-low pressure tires (so-called balloon tires).

46 is an engine mounted near the center of the vehicle body. A transmission case 48 is fixed to the vehicle body frame 10 between the engine 46 and the rear axle 34 and offset to the left. The output of the engine 46 is transmitted via a group of transmission gears in the transmission case 48 and a drive shaft (not shown) disposed in the vehicle width direction from the rear end of the transmission case 48 to a final reduction gear provided on the rear axle 34. 50 will be informed. A PTO shaft 51 is disposed near the center in the vehicle width direction on the right side of the transmission case 48, and the output of the engine 46 is transmitted to the PTO shaft 51 via a belt clutch 52 in an intermittent manner.

Reference numeral 54 denotes a straddle-type driver's seat that is long in the front-rear direction and is installed so that it can be opened and closed upward using its rear end as a fulcrum. That is, as shown in FIG. 1.3, a pair of left and right support plates 58.58 are fixed to the rear of the seat bottom plate 56 so as to hang down, and these support plates 58.58 are attached to a bracket fixed to the lower tube 12.12. 60.60 by means of pins 62.62. Further, a hook 64 is swingably attached to the front portion of the seat bottom plate 56, and the hook 64 can be engaged with and detached from a retaining piece 66 fixed to the upper tube 14. That is, the hook 64 has a tendency to return clockwise in FIG. 1 by the torsion spring 68, and when the hook 64 is rotated counterclockwise by operating a seat lever (not shown), it engages with the engagement piece 66. is released and the driver's seat 54
can be opened upward. Further, when the driver's seat 54 is closed, the hook 64 engages with the engagement piece 66 and is locked in this state. Note that the lower surface of the seat bottom plate 56 is connected to the upper tube 14.
It is supported by brackets 70, 72 fixed to 14.

A seat switch 74 is attached to the upper surface of the seat bottom plate 56 near the center. The wiring cord 76 of this seat switch is connected to a hook 78 provided on the underside of the seat bottom plate 56.
The pin 6, which is the fulcrum when opening and closing the driver's seat 54,
2, and is further led to the vehicle body side via a connector 80.

Note that, as shown in FIG. 2, a carburetor 82 and an air purifier 84 are provided below the driver's seat 54. Also the first
In the figure, 86 is a fuel tank, 88 is a battery, 90 is a front fender, and 92 is a rear fender.

Therefore, even if the driver's seat 54 is opened in the L direction for maintenance and inspection of the carburetor 82, air purifier 84, etc., the wiring cord 76 of the seat switch 74 is only bent near the pin 62 as a fulcrum, and the wiring Code 76 does not become an obstacle to maintenance inspections.

Further, since the wiring cord 76 is provided with a connector 80, when the driver's seat 54 is removed, the wiring cord 76 can be conveniently divided into the vehicle body side and the driver's seat side by the connector 80.

FIG. 4 is a side sectional view showing the vicinity of the fulcrum of another embodiment of the present invention. In this embodiment, a rubber hinge 8 connects the bracket 60A fixed to the lower tube 12A and the seat bottom plate 56A.
2 and use this hinge 82 as a fulcrum to operate the seat) 5
4A can be opened upwards. Note that 76A is a wiring cord, 78A is a hook, and 80A is a connector.

The present invention is applicable not only to automatic 2, 3, and 4 wheel vehicles, but also to snowmobiles and the like, and includes such vehicles.

(Effects of the Invention) As described above, the present invention enables the straddle-type driver's seat to be opened and closed upward using either the front or rear as a fulcrum, and connects the seat switch wiring cord to the vehicle body through the vicinity of this fulcrum. The wiring cord will not become an obstacle when opening the door and performing maintenance and inspection of the auxiliary equipment located below.
