Description

[Detailed Description of the Invention] The present invention relates to a seat for a motorcycle.

Motorcycle seats are designed to lower the height of the driver's seat so that the driver's feet can rest on the ground in order to make driving easier and safer when the motorcycle is stopped, driving on rough roads, or in large, heavy vehicles. It is necessary to make it easy to use. On the other hand, the passenger seat is normally located behind the driver's seat and above the rear wheels, and due to the arrangement of the rear wheel mudguards, it cannot be placed as low as the driver's seat. There is a problem.

Conventionally, motorcycle seats have been installed at a high height, and the upper surface of the seat for the driver and passenger is generally flat with no difference in level, so the driver can sit in a desired position according to his or her body position. It was easy to move around. However, if both the driver's seat and the passenger's seat are integrally formed in the front and rear in an attempt to solve the above-mentioned problem, the upper surface will have a step, commonly called a flip-up or stepped seat. Therefore, the seating position of the driver's seat is determined by this step, and it cannot follow the size of the driver's physique or preferred driving position, making it difficult for the driver to enjoy a comfortable ride.
Moreover, there are problems such as getting tired easily when sitting for a long time.

Therefore, the stepped integrated seat of a motorcycle (see Figure 8 showing a conventional example) is slidably supported on the vehicle body frame, and the stepped integrated seat allows the rider to take the desired driving posture. There are some models in which the stepped seat is adjusted and fixed at an arbitrary position in the longitudinal direction of the vehicle, but in this structure, when the stepped seat a is moved backward, a gap is created between the tip of the stepped seat and the rear of the fuel tank b. Not only does this cause a bad appearance, but also the fuel tank and auxiliary equipment such as electrical equipment located at the bottom of the stepped seat become dirty due to the infiltration of rainwater.
Furthermore, in order to prevent interference between the stepped seat a and the rear wheel fender d, it is necessary to remove part f of the cushion material at the bottom of the rear end of the driver's seat e.
There is a problem in that the performance of the cutlet is deteriorated. (See Japanese Utility Model Application Publication No. 56-44980 as an example.) The present invention was made in view of the above problem, and the seat is formed as separate parts for the driver's seat and the passenger's seat. The purpose of the present invention is to solve the above-mentioned problems by fixing the seat at an optimal position, and by making the passenger seat movable back and forth above the driver's seat and fixed at a predetermined position. shall be.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Figure 1 is a side view of a motorcycle equipped with the seat of the present invention, Figure 2 is a plan view of the seat, and Figure 3 is a cross-section of the driver and passenger seats taken along the - line in Figure 2. FIG. 4 is a cross-sectional view of the passenger seat taken along the - line in FIG. 3, and FIGS. 5 and 6 are side views of the slide mechanism for attaching the passenger seat. and a plan view, and FIG. 7 is a sectional view taken along the - line in FIG. 6.

1 is a motorcycle, 2 is a frame of the vehicle body, 3 is an engine, 4 is a fuel tank, and 5 is a seat attached to the frame 2, which is divided into a driver's seat 6 and a passenger seat 7, and is formed separately. The passenger seat 7 is located above the rear wheel fender 8. The planar shapes of the driver's seat 6 and the passenger's seat 7 are schematically shown in FIG. 2, and their cross-sectional shapes in the vehicle length direction are shown in FIG. 3, respectively.

The driver's seat 6 consists of a front cushion 10 fixed on a fixed plate 9, and the fixed plate has front mounting pieces 11, 11 extending from both sides of the front end toward the front, and front mounting pieces 11, 11 on both sides of the rear end. Rear mounting pieces 12, 12 extend rearward from the left and right sides, respectively.
The driver's seat 6 is fixed by fastening the left and right rear mounting pieces 12, 12 to the frame 2 with bolts 14, 14. An intermediate portion of the fixed platen 9 is supported by the frame 2 via a seat 15.

The passenger seat 7 consists of a movable platen 16 and a rear cushion 17 fixed on the movable platen, and the lower bottom portion 18 of the movable platen is connected to the front cushion 10.
It is arranged so as to cover the upper surface 19 of the rear end portion, and the front end portion is formed similar to the shape of the upper surface of the front cushion 10, and the intermediate portion and rear end portion are formed as shown in FIG. In order to maintain space above the rear wheel fender 8, the central part 20 in the vehicle width direction is formed into a trapezoidal shape that is higher than the horizontal parts 21, 21 on both sides. The four protruding movable plate mounting pieces 22 are connected to slide mechanisms 24a and 2 of the positioning means 23, which will be described later.
4b.

Positioning means 23 (see Figures 2 and 3)
consists of a pair of left and right sliding mechanisms 24a (see Figs. 2 to 6) and 24b (see Figs. 2 and 4), which are mounted on the frame 2, and the structure of the sliding mechanism 24a is the fifth (top view), FIG. 6 (side view) and FIG. 7 (sectional view),
It is composed of a fixed rail 25, a movable rail 26, steel balls 27, 27, etc., and is also equipped with a seat fixing mechanism, but one slide mechanism 24
b is not equipped with a seat fixing mechanism 28. To explain the slide mechanism 24a, each of the fixed rails 25, 25 has a groove-shaped cross section as shown in FIG. Fixed as shown. Each of the moving rails 26 is a seventh
As shown in the figure, it has a groove-shaped cross section and is formed to be narrower and taller than the fixed rail 25. Between the steel balls 27 and 30 and the inner flanges 31 and 31 of the fixed rail 25,
7. Interpose... Protrusions 34, 34, .
(See Figures 5 and 6) are formed at appropriate intervals,
This protrusion restricts the position of the steel ball 27 on the moving rail 26 so that it is not unevenly distributed left and right. 35 and 36 are moving rails 26
It is a stopper.

The seat fixing mechanism 28 (see FIGS. 5 to 7) includes an engagement hole 37 provided in the moving rail 26,
The main part is a fixing knob 38 that is attached to the fixed rail 25 and can be moved in and out of the engagement hole. A total of four engaging holes 37 are formed at equal intervals, and the fixing knob 38 has a locking claw 39 at its upper end.
On the other hand, a support shaft 41 of a bearing part of a bracket 40 fixedly installed on the bottom plate part of the fixed rail 25 is extended.
The fixing knob 38 is pivoted to the support shaft 4.
The locking pawl 39 fits into the engagement hole 37 under the force of the spring 42 fitted into the locking hole 37 . Therefore, the moving rail 26 is fixed to the fixed rail 25. Mounting holes 3 are provided in the upper wall 32 of the moving rail 26.
3, 33 are drilled, and by attaching the mounting pieces 22, 22... attached to the movable plate of the passenger seat to the mounting holes, the passenger seat 7 can be moved back and forth with respect to the fixed rail 25. Moreover, it can be fixed in any hole position by the sheet fixing mechanism 28. Incidentally, in order to position the passenger seat at the rear when the passenger seat 7 is at the front end position in the moving direction (dotted line in FIGS. 2 and 3), the fixing knob 38 of the seat fixing mechanism 28 is pressed. Remove the locking pawl 39 from the engagement hole 37 by operating (chain line in Figure 7)
At the same time, the passenger seat 7 is moved rearward, and then the locking claw 39 is inserted into the front engagement hole 37 again.
to fix the passenger seat 7.

In the present invention, the driver's seat and the passenger's seat are formed separately with the above structure, so the driver's seat can be fixed to the vehicle body frame with a low seat height, and the passenger's seat can be fixed to the vehicle body frame. Since the driver's seat is fixed at an arbitrary position by the positioning means, the driver can move the seating position to a desired position according to his/her body position, so that driving can be carried out comfortably.
