On the other hand, a circular hole is formed in the front end portion of the link attachment portion 34, and a portion of the end portion of the front side connecting pipe 43 that protrudes to the outside of the front side link 41 is inserted into this circular hole. Further, the end of the pipe is flanged. As a result, each of the pair of front links 41 can be attached to the link attachment portion 34 via the front connecting pipe 43. Further, the front connecting pipe 43 is assembled to the link mounting portion 34 in a state of being rotatable with respect to the link mounting portion 34. As a result, the upper end of each front link 41 is supported by the link attachment portion 34 in a state where it can rotate integrally with the seat support plate 30.

Further, the lower end of each front link 41 (the end opposite to the side supported by the link mounting portion 34) is supported by the side wall in a state of being relatively rotatable with respect to the side wall of the link support plate 50. Has been done. Specifically, a circular hole is formed at the lower end of each front link 41, and an annular bush is fitted at the edge thereof. Then, the pivot pin P is fitted in the through hole of the bush. Further, the pivot pin P fitted in the through hole of the bush is fixed to the side wall of the link support plate 50. The link support plate 50 is a member made of a metal plate formed in a substantially U shape when viewed from the front, and has a bottom wall and a pair of side walls rising from the bottom wall.

As described above, the lower end of the front link 41 is supported by the side wall of the link support plate 50 via the pivot pin P described above. Further, the pivot pin P can slide on the inner peripheral surface of the bush attached to the lower end portion of the front link 41. In other words, the front link 41 is rotatable around the pivot pin P as a rotation axis.

With the same configuration as the support structure described above, the pair of rear links 42 are rotatably attached to the link attachment portion 34 and the link support plate 50 of the seat support plate 30. Specifically, the pair of rear links 42 are connected by rear connecting pipes 44 arranged between them. Further, the end portion of the rear connecting pipe 44 penetrates the rear link 42 and projects to the outside of the rear link 42. On the other hand, a circular hole is formed at the rear end of the link attachment portion 34, and a portion of the end of the rear connecting pipe 44 that protrudes to the outside of the rear link 42 is inserted into the circular hole. Further, the end of the pipe is flanged. As a result, each of the pair of rear links 42 is attached to the link attachment portion 34 via the rear connecting pipe 44.

Further, the rear connecting pipe 44 is assembled to the link mounting portion 34 in a state of being rotatable with respect to the link mounting portion 34. As a result, the upper end of each rear link 42 is supported by the link attachment portion 34 in a state where it can rotate integrally with the seat support plate 30.

Further, the lower end of each rear link 42 (strictly speaking, the end opposite to the side supported by the link mounting portion 34) is in a state of being relatively rotatable with respect to the side wall of the link support plate 50. Is supported by the side wall. Specifically, a circular hole is formed at the lower end of each rear link 42, and an annular bush is fitted at the edge thereof. A pivot pin P is fitted in the through hole of the bush. Further, the pivot pin P fitted in the through hole of the bush is fixed to the side wall of the link support plate 50.

As described above, the lower end of the rear link 42 is supported by the side wall of the link support plate 50 via the pivot pin P described above. Further, the pivot pin P can slide on the inner peripheral surface of the bush attached to the lower end portion of the rear link 42. In other words, the rear link 42 is rotatable around the pivot pin P as a rotation axis.

The front link 41 and the rear link 42 configured as described above rotate all at once about a rotation axis along the width direction. At this time, each rotation link 40 rotates so as to rotate around the seat support plate 30. As a result, the seat support plate 30 and the seat 2 supported by the seat support plate 30 rotate in the same direction as the rotation direction of the rotation link 40, whereby the seat position (seat height) is adjusted. become.

The front link 41 and the rear link 42 are attached to the link attachment portion 34 of the seat support plate 30 as described above. The link attachment portion 34 is arranged at the same position as the front portion 31 of the link attachment portion 34 (on both sides of the front portion 31). Further, the front portion 31 is located directly below the buttocks of the occupant in a state where the occupant is seated on the seat 2. In such a configuration, when adjusting the seat position, the front portion 31 on which the buttocks of the occupant rests is moved in conjunction with the rotational operation of the rotary link 40. As a result, the seat position can be adjusted more efficiently (smoothly).

The link support plate 50 supports the lower end portion of the rotating link 40 so that the rotating link 40 can rotate as described above. The link support plate 50 is arranged at a position below the seat support plate 30, or more strictly, at a position below the front portion 31.

The base plate 52 is a base provided for fixing the device 20 at a predetermined position (seat mounting position) of the vehicle body 3, and is located at the lowermost position in the device 20. The base plate 52 is formed by bending a metal plate cut into a predetermined shape so as to have the shape shown in FIG. Further, a plurality of protruding portions protruding in a tongue shape or a rectangular shape are provided at the end portion of the base plate 52 in the lateral width direction. Each protruding portion is arranged so as to face a predetermined portion of the vehicle body 3 (specifically, a portion originally provided for attaching the seat 2). Further, a screw hole is formed in each protruding portion, a screw is inserted into the screw hole, and the tip portion of the screw is fastened to the vehicle body 3. As a result, the entire device 20 including the base plate 52 is fixed to the vehicle body 3.

The motor device 60 is a device that drives the rotation link 40 to rotate. The motor device 60 is supported by the link support plate 50 via two support rods (specifically, a front support rod 63 and a rear support rod 64). Specifically, the motor device 60 is fixed to one end of both ends of the front support rod 63, and the other end is bolted to the side wall (one of the pair of side walls) of the link support plate 50. Further, one end of both ends of the rear support rod 64 is bolted to the side wall of the link support plate 50 (the side wall opposite to the side on which the front support rod 63 is fixed), and the motor device 60 is attached to the other end. It is fixed. As shown in FIG. 3, rod fixing holes 50a for fixing the support rods are formed on each of the side walls of the link support plate 50.

Further, as shown in FIG. 3, the motor device 60 includes a motor main body 61 and a transmission mechanism 62 for transmitting the rotational energy of the motor main body 61. The transmission mechanism 62 has a gear train wheel (not shown) that rotates with the rotation of the motor body 61. The gear provided at the final stage of the gear train is a pinion gear and meshes with the sector gear. The sector gear is provided on one of the pair of rear links 42, and is strictly formed integrally with the rear link 42.

Then, when the motor body 61 rotates, the meshing position between the pinion gear and the sector gear changes, and the rear link 42 rotates accordingly, and the remaining rotating link (that is, the sector gear) follows this. The rear link 42 paired with the provided rear link 42 and the two front links 41) rotate in the same direction.

<< Operation example of seat device 10 >>
Next, an operation example of the seat device 10 described above will be described. In the seat device 10, when the motor body 61 of the motor device 60 rotates, the rotational energy is transmitted to one of the rear links 42 by the transmission mechanism 62. As a result, the four rotating links 40 (that is, the two front links 41 and the two rear links 42) rotate integrally with the seat support plate 30. As a result, the seat 2 supported by the seat support plate 30 moves in the height direction, and as a result, the seat position (seat height) changes.

Hereinafter, the moving operation of the sheet 2 will be described in detail with reference to FIGS. 7 and 8. The sheet 2 moves within the range from the position shown in FIG. 7 to the position shown in FIG. In other words, the position of the seat 2 is adjusted within the above range. Here, the position of the sheet 2 illustrated in FIG. 7 is the lowest position (the position on the lowermost side) in the moving range of the sheet 2, and is hereinafter referred to as the first position. The position of the sheet 2 shown in FIG. 8 is the highest position (the position on the uppermost side) in the moving range of the sheet 2, and is hereinafter referred to as a second position. In the height direction, the second position is a position above the first position, in other words, a position farther from the ground on which the motorcycle 1 is in contact with the first position.

Further, when the position of the seat 2 is in the first position, as shown in FIG. 7, each of the front side link 41 and the rear side link 42 is in the forward tilted state. On the other hand, when the position of the seat 2 is in the second position, the states of the front link 41 and the rear link 42 are higher than when the position of the seat 2 is in the first position, as shown in FIG. The forward tilt angle (degree of tilt) is small. That is, when the motor body 61 rotates when the position of the seat 2 is in the first position, each rotation link 40 in the forward tilted state at that time starts to rotate backward. Then, as the position of the seat 2 moves from the first position to the second position, the forward tilt angle of each rotation link 40 gradually decreases. Strictly speaking, the position of the seat 2 moves from the first position to the second position by gradually changing the state of each rotation link 40 so that the forward tilt angle gradually decreases.

As described above, in the present embodiment, the seat 2 moves in conjunction with the rotation operation of the rotation link 40, whereby the seat position is adjusted. That is, in the present embodiment, the seat position can be adjusted by a relatively simple configuration (that is, a height link mechanism) using the rotating link 40.

Further, when the seat 2 moves from the first position to the second position due to the rotation operation of the rotation link 40, the seat 2 rises diagonally backward. That is, the second position is an upper position of the first position in the height direction and a rear position of the first position in the front-rear direction. With such a movement path, when the seat 2 moves from the first position to the second position, another member (specifically, a member arranged around the seat 2 such as a fuel tank T or the like). ) Can be suppressed.

The movement direction when the seat 2 moves from the first position to the second position is not limited to the above-mentioned direction (that is, the direction of ascending diagonally backward), and may be another direction. Specifically, the second position may be set to the position above the first position in the height direction and to the front position of the first position in the front-rear direction. In such a configuration (hereinafter, a modified example), the rotation operation of the rotation link 40 (specifically, the state change of each rotation link 40 from the backward tilted state to the forward tilted state) is shown in FIGS. 14 and 15. As shown, the seat 2 rises diagonally forward from the first position to the second position. At this time, the seat 2 moves along the fuel tank T arranged diagonally above the seat 2. With such a configuration, the space between the fuel tank T and the seat 2 can be narrowed, and the appearance of the seat can be improved. 14 and 15 are explanatory views of the seat position adjustment according to the modified example, FIG. 14 is a view when the seat 2 is in the first position, and FIG. 15 is a view in which the seat 2 is in the second position. It is a figure at a certain time.

When the sheet 2 is moved from the first position to the second position in the above-mentioned movement direction, the device shown in FIGS. 16 and 17 (hereinafter, the device 120 according to the modified example) is used. FIG. 16 is an exploded view of the device 120 according to the modified example, and is a view corresponding to FIG. FIG. 17 is a diagram showing a configuration in which the device 120 according to the modified example is attached to the vehicle body, and is a diagram corresponding to FIG.

The device 120 according to the modified example has a slight shape change due to a difference in the moving direction of the seat 2, for example, the sector gear is provided on the front link 41 instead of the rear link 42, but basically. , The same configuration as described above (the seat 2 rises diagonally rearward from the first position to the second position). Further, each device constituting the device 120 according to the modified example has the same structure as the above-described configuration except that the rotation direction of the rotation link 40 is reversed in the front-rear direction. Therefore, the components of the device 120 according to the modified examples shown in FIGS. 16 and 17 are designated with the same reference numerals as the corresponding devices in the above-described configuration.

By the way, when the seat 2 moves from the first position to the second position, the seat 2 is separated from the vehicle body 3 by a distance corresponding to the amount of deviation between the first position and the second position. That is, the gap between the seat 2 and the vehicle body 3 is increased by the amount corresponding to the above-mentioned displacement amount. If the gap between the seat 2 and the vehicle body 3 is increased in this way, foreign matter may enter through the gap, or the inside of the vehicle body 3 may be visible through the gap, impairing the appearance.

On the other hand, in the present embodiment, when the gap between the seat 2 and the vehicle body 3 increases, the gap can be closed. More specifically, in the present embodiment, the gap closing member 70 is provided between the front end of the seat 2 and the member (for example, the fuel tank T) facing the front end of the seat 2. The gap closing material 70 is a stretchable fabric, and is fastened to both the front end of the sheet 2 and the member facing the front end.

Further, when the sheet 2 is in the first position, the gap closing member 70 is arranged at a position sandwiched between the front end of the sheet 2 and a member facing the sheet 2 (position shown by a solid line in FIG. 9). .. Then, when the seat 2 moves from the first position to the second position, the gap between the front end of the seat 2 and the member facing the front end of the seat 2 increases in the front-rear direction. At this time, the stretchable gap closing material 70 extends in the front-rear direction to close the gap, as shown by the broken line in FIG. As a result, even if the above-mentioned gap increases in the front-rear direction, it is possible to avoid the trouble caused by the gap by covering the increased gap.

Further, in the present embodiment, as shown in FIG. 10, the cover plate 71 is attached to the side end (end surface in the lateral width direction) of the rear end portion of the sheet 2. The cover plate 71 covers the gap between the rear end portion of the seat 2 and the member (for example, the cowl) located directly below the rear end portion in the height direction, and when the seat 2 moves, the cover plate 71 and the seat 2 Move in one piece. Further, as shown in FIG. 11, the cover plate 71 is arranged so that the lower end of the cover plate 71 is located slightly below the lower end of the rear end portion of the sheet 2 in the height direction. Further, when the seat 2 is in the first position, the cover plate 71 is arranged at a position straddling the rear end portion of the seat 2 and the member located directly below the rear end portion in the height direction. In other words, when the seat 2 is in the first position, the lower end of the cover plate 71 is located slightly below the upper end of a member (eg, cowl) located just below the rear end of the seat 2. ..

On the other hand, when the seat 2 moves from the first position to the second position, the gap between the rear end portion of the seat 2 and the member located immediately below the rear end portion increases in the height direction. At this time, the cover plate 71 rises together with the seat 2, but the lower end of the cover plate 71 is still located below the upper end of the member located directly below the rear end portion of the seat 2. That is, even when the seat 2 is in the second position, the cover plate 71 is in a position straddling the rear end portion of the seat 2 and the member (for example, the cowl) located directly below the rear end portion in the height direction. .. As a result, even if the gap between the rear end portion of the sheet 2 and the member located directly below the rear end portion increases, the gap is covered by the cover plate 71 from the side. As a result, even if the above-mentioned gap increases in the height direction, the increased gap can be covered, and as a result, the trouble caused by the gap can be avoided. In particular, it is possible to prevent rainwater from entering through the above-mentioned gap in rainy weather.

As a member for closing the gap between the seat 2 and the device located in front of the seat 2, instead of the above-mentioned gap closing member 70, the second cover plate shown in FIG. 18 (hereinafter referred to as the front cover plate 72) ) May be used. FIG. 18 is a diagram showing the configuration of the seat 2 and its peripheral equipment (specifically, the fuel tank T).

The front cover plate 72 is arranged between the front end portion of the seat 2 and the fuel tank T located immediately before the seat 2. As shown in FIG. 18, the front cover plate 72 is bent in a substantially U shape and is attached to the rear end portion of the fuel tank T. When the seat 2 is in the first position, the front cover plate 72 is located between the fuel tank T and the seat 2 in the front-rear direction. At this time, the front end portion of the seat 2 is adjacent to the front cover plate 72. That is, when the seat 2 is in the first position, the front end portion of the seat 2 is in a position overlapping the rear end portion of the fuel tank T in the vertical direction.

On the other hand, when the seat 2 moves from the first position to the second position, the seat 2 rises, and the gap between the front end portion of the seat 2 and the rear end portion of the fuel tank T increases accordingly. .. Even when the seat 2 reaches the second position, the front end portion of the seat 2 is adjacent to the front cover plate 72 in the vertical direction. As a result, even when the seat 2 is in the second position, the front cover plate 72 closes the gap between the seat 2 and the fuel tank T in the vertical direction. As a result, even if the gap between the front end portion of the seat 2 and the rear end portion of the fuel tank T increases, the increased gap can be covered by the front cover plate 72, and the trouble caused by the gap can be avoided. It becomes possible.
The front cover plate 72 has a configuration in which the seat 2 rises diagonally backward when the seat 2 moves from the first position to the second position, and the front cover plate 72 rises diagonally forward when the seat 2 moves from the first position to the second position. Applicable to any of the configurations.

<< Control example of seat device 10 >>
Next, a control example of the seat device 10 will be described. First, in explaining a control example of the seat device 10, the control mechanism used for controlling the seat device 10 will be described with reference to FIGS. 12 and 13.

As shown in FIG. 12, the above control mechanism includes an ECU (Electronic Control Unit) 80 as a controller. The ECU 80 is provided at a predetermined position on the vehicle body 3, and automatically controls the position of the seat 2 according to the traveling speed of the motorcycle 1. More specifically, the ECU 80 controls the motor device 60 according to the traveling speed of the motorcycle 1. As a result, the rotation direction and the rotation amount of the rotation link 40 are controlled, and as a result, the seat position (seat height) is adjusted to a position corresponding to the traveling speed of the motorcycle 1.

More specifically, the above-mentioned control mechanism monitors the traveling speed of the motorcycle 1, and specifically includes a sensor 81 for detecting the traveling speed. When the sensor 81 detects the traveling speed, it outputs a signal according to the detection result. When the ECU 80 receives the output signal from the sensor 81, the ECU 80 identifies the detection result of the sensor 81 (that is, the traveling speed of the motorcycle 1) from the signal.

After specifying the traveling speed, the ECU 80 compares the specified traveling speed with the threshold value stored in advance in the ECU 80. Here, there are two types of threshold values, one is a threshold value used when determining whether or not to execute an operation (elevation operation) for moving the seat 2 toward the second position. It is called the threshold value. The other threshold value is a threshold value used when determining whether or not to execute an operation (lowering operation) of moving the seat 2 toward the first position, and is hereinafter referred to as a deceleration threshold value.

Explaining the above two threshold values by giving an example, the threshold value for traveling is set in the range of 70 to 90 km / h, and in the present embodiment, it is set to 80 km / h. Further, the threshold value for deceleration is set in the range of 30 to 50 km / h, and in the present embodiment, it is set to 40 km / h. The running threshold value and the deceleration threshold value are not limited to the above values, and can be set to any value.

Further, in the present embodiment, each threshold value can be changed ex post facto. Specifically, an input means (not shown) is mounted at a predetermined position of the motorcycle 1, and when the input means receives an operation of changing the threshold value by the occupant, the ECU 80 updates the threshold value to the changed value. NS. If it is possible to change the threshold value after the fact in this way, the control conditions will be set according to the preference of the user (occupant).

Then, the ECU 80 controls the motor device 60 according to the flow shown in FIG. Specifically, the motorcycle 1 is mounted on an operation panel (not shown), and the operation panel is provided with an operation switch 82 that is turned on and off by an occupant. The ECU 80 switches whether or not to execute the seat position adjustment according to the on / off of the operation switch 82. In this embodiment, the ECU 80 controls the motor device 60 only when the operation switch 82 is on. That is, the seat position adjustment is executed only when the operation switch 82 is on, and is not executed when the operation switch 82 is off. As described above, in the present embodiment, the presence / absence of the seat position adjustment can be freely switched by operating the operation switch 82, so that the occupant can specify the presence / absence of the seat position adjustment at his / her own will. It becomes.

Then, when the operation switch 82 is on (Yes in S001), the ECU 80 controls the motor device 60 to adjust the seat position when the traveling speed is compared with each threshold value and a predetermined condition is satisfied. .. More specifically, when the motorcycle 1 shifts from the stopped state to the traveling state, the ECU 80 identifies the traveling speed of the motorcycle 1 based on the output signal from the sensor 81 (S002). Then, when the specified traveling speed becomes equal to or higher than the traveling threshold value (Yes in S003), the ECU 80 controls the motor device 60 so that the seat 2 starts the ascending operation (S004). As a result, the seat 2 starts to move from the first position to the second position. Then, the ECU 80 stops the motor device 60 when the seat 2 reaches the second position.

On the other hand, when the motorcycle 1 decelerates, the ECU 80 specifies the traveling speed of the motorcycle 1 (S005), and when the specified traveling speed becomes equal to or less than the deceleration threshold value (Yes in S006), the seat 2 descends. The motor device 60 is controlled to start (S007). As a result, the seat 2 moves from the second position to the first position. In the present embodiment, the ECU 80 controls the motor device 60 so that the seat 2 reaches the first position when the traveling speed is reduced to a predetermined speed, strictly speaking, when the motorcycle 1 is stopped.
