Abstract

PROBLEM TO BE SOLVED: To accomplish a saddle-riding vehicle with comfortable ride quality under various situations or in accordance with the preference of a driver or the like by making elasticity of a seat variable.SOLUTION: In a seat bottom 21 of a seat 11, an adjustable vent hole 30 is formed in a portion where a cushion rubber 25 is mounted. In the cushion rubber 25, a large passage 43 is formed between its top face and one side face, and a small passage is formed between the top face and another side face. Thus, air can be circulated between the inside and the outside of the seat 11. When the cushion rubber 25 is mounted to the seat bottom 21 in such a mount direction as illustrated, the adjustable vent hole 30 and the large passage 43 are communicated and the quantity of air to be circulated is increased. When the cushion rubber 25 mounted as illustrated is removed and mounted again after being rotated at 180° in a horizontal direction, the adjustable vent hole 30 and the small passage are communicated, and the quantity of air to be circulated is reduced. By varying the quantity of air to be circulated between the inside and outside of the seat, elasticity of the seat is varied.

Description

  The present invention relates to a seat for a saddle type vehicle such as a motorcycle or a bicycle.

  For example, a motorcycle is provided with a seat for a driver, or in the case of two passengers, a driver and a passenger to sit (strip). The seat of a motorcycle is formed by providing a cushion material on a seat bottom corresponding to a lower plate and covering the cushion material with a seat skin. The seat of the motorcycle is attached to a seat rail connected to the vehicle frame of the motorcycle via a locking member or the like provided on the seat bottom. Further, in the motorcycle, for example, a battery or the like is accommodated below the seat. Therefore, the seat can be detached from the motorcycle by removing it from the seat rail in order to allow the user to replace the battery. A motorcycle seat is described, for example, in Patent Document 1 below.

JP 2001-114147 A

  By the way, some motorcycle seats have air holes formed in the seat bottom. When the driver or passenger sits on the seat, the cushion material is crushed by the load applied to the seat, and the air in the seat, that is, between the seat skin and the seat bottom, passes through the vents formed in the seat bottom. Out of the seat. In addition, when vibration occurs during traveling of the motorcycle, the load applied to the seat from the driver increases and decreases according to the vibration, so the seat cushion material repeatedly contracts and restores according to the increase and decrease of the load. . Thus, while the cushion material repeats contraction and restoration, air flows between the inside of the seat and the outside of the seat through the air holes formed in the seat bottom. By such air circulation through the air holes, the cushioning material can be easily deformed, and the seat can be made to exhibit appropriate elasticity. Thus, in general, for the driver or passengers The riding comfort of the motorcycle can be improved.

  However, the degree of deformation of the cushion material of the seat changes depending on factors such as the weight of the driver, whether one or two people are seated on the seat, and the magnitude of vibration (for example, the road surface condition) that occurs during traveling. To do. For this reason, the seat may not exhibit appropriate elasticity due to these factors, and ride comfort may deteriorate. In this case, it is possible to improve the riding comfort by changing the elasticity of the seat by exchanging the cushion material, but this is troublesome and is not practical. Also, if the amount of air flowing through the vent hole formed in the seat bottom can be adjusted, it is possible to improve the riding comfort by changing the elasticity of the seat, but it is formed in the seat bottom. The area of the vents is unchanged. For this reason, it is not easy to improve the deterioration of the riding comfort due to the above factors by changing the elasticity of the seat.

  Also, some drivers prefer a sheet with a hard feel, for example, and some prefer a sheet with a soft feel. For this reason, if the elasticity of the seat can be changed according to the preference of the driver or the like, it is possible to realize a motorcycle that is comfortable to ride for each driver or the like. However, after all, replacement of the cushion material takes time, and the air circulation amount cannot be adjusted because the area of the vent hole is unchanged. Therefore, the elasticity of the seat cannot be changed, and it is difficult to realize a motorcycle that is comfortable to ride for each driver or the like.

  These problems can occur not only in motorcycles but also in other saddle-type vehicles such as bicycles.

  The present invention has been made in view of the above-described problems, for example, and can change the elasticity of the seat. The saddle type has a good ride comfort in various situations or according to the preference of the driver or the like. An object of the present invention is to provide a saddle type vehicle seat capable of realizing a vehicle.

  In order to solve the above problems, a first saddle type vehicle seat according to the present invention is a saddle type vehicle seat provided on a saddle type vehicle and on which a driver or a passenger sits, and is attached to the saddle type vehicle. A lower plate portion, a cushion material provided on the lower plate portion, a cover that covers the cushion material, and the space between the inside and the outside of the space surrounded by the lower plate portion and the cover. And a flow mechanism for flowing air between the inside and the outside of the space, and an adjustment mechanism for adjusting the amount of air flowing through the flow mechanism.

  According to the first saddle-type vehicle seat of the present invention, the amount of air flowing between the inside and the outside of the seat can be adjusted by the adjusting mechanism, thereby changing the elasticity of the seat. it can. Therefore, depending on the weight of the driver or passengers, whether there are two people sitting on the seat, the magnitude of vibrations (for example, road conditions) that occur during driving, the driver's or passenger's preference, etc. The riding comfort of the motorcycle can be improved.

  In order to solve the above problems, a second saddle type vehicle seat according to the present invention is the above-described first saddle type vehicle seat according to the present invention, in which the distribution mechanism is formed on the lower plate portion. The adjusting mechanism is a mechanism that restricts an amount of air flowing through the vent hole by blocking a part of the vent hole.

  According to the second saddle type vehicle seat of the present invention, a seat whose elasticity can be changed with a simple structure in which a vent hole is formed in the lower plate portion and an adjustment mechanism for blocking a part of the vent hole is provided. Can be realized.

  In order to solve the above-described problem, a third saddle type vehicle seat according to the present invention is the above-described second saddle type vehicle seat according to the present invention, wherein the adjustment mechanism is attached to the lower plate portion, A shielding member for shielding a part of the opening of the vent hole is provided.

  According to the third saddle type vehicle seat of the present invention, it is possible to realize a seat whose elasticity can be changed with a simple structure in which the shielding member is attached to the lower plate portion. Further, if the above-described shielding member is attached to the lower surface of the lower plate portion, the user can directly touch the shielding member attached to the lower surface of the lower plate portion by removing the seat from the saddle type vehicle. . Then, the user can easily select whether or not to block the opening of the vent hole by the shielding member by attaching / detaching the shielding member, changing the mounting position, or changing the mounting direction, or the like. It is possible to easily change the degree of blocking the opening of the vent hole by the member. As a result, the user can easily change the elasticity of the seat.

  In order to solve the above-described problem, a fourth vertical vehicle seat according to the present invention is the above-described third vertical vehicle seat according to the present invention, wherein the adjustment mechanism is configured to shield the lower plate portion. The degree to which the opening of the vent hole is blocked is changed by changing the position or direction in which the member is attached.

  According to the fourth saddle-type vehicle seat of the present invention, the user can change the degree of shielding the opening of the vent hole by a simple operation such as changing the attachment position or the attachment direction of the shielding member. The elasticity of the can be changed.

  In order to solve the above-mentioned problems, a fifth vertical vehicle seat according to the present invention is the above-described fourth vertical vehicle seat according to the present invention, wherein the shielding member includes a groove or a hole. A first passage for allowing air to flow out from the opening of the gas or to flow into the opening of the vent, and a groove or a hole, which flows out of the vent or from the vent. A second passage for allowing air to pass therethrough, the passage areas of the first passage and the second passage being different from each other, and changing a position or a direction in which the shielding member is attached to the lower plate portion. Thus, the passage connected to the vent hole is switched between the first passage and the second passage.

  In the fifth saddle-type vehicle seat of the present invention, when the position (direction) where the shielding member is attached to the opening of the vent hole is the first position (first direction), the vent hole and the first The passage is connected. In this case, for example, if the passage area of the first passage is larger than the passage area of the second passage, the degree to which the opening of the vent hole is blocked by the shielding member becomes relatively small. As a result, the amount of air flowing between the inside and the outside of the space in the seat through the vent hole becomes relatively large, and the air easily flows, so that the seat is easily deformed according to the load and is soft. It feels like a ride. On the other hand, when the position (direction) for attaching the shielding member to the opening of the vent hole is the second position (second direction), the vent hole and the second passage are connected. In this case, for example, if the passage area of the second passage is smaller than the passage area of the first passage, the degree to which the opening of the vent hole is blocked by the shielding member becomes relatively large. As a result, the amount of air flowing between the inside and the outside of the space in the seat through the vent hole is relatively small, and it is difficult for the air to flow. Therefore, the seat is difficult to deform according to the load, and is hard. It feels like a ride. In this way, the elasticity of the seat can be easily changed and the riding comfort can be changed simply by switching the mounting position or mounting direction of the shielding member.

  In order to solve the above problems, a sixth saddle type vehicle seat according to the present invention is the above-described fifth saddle type vehicle seat according to the present invention, wherein the shielding member is formed of an elastic material and is added to the seat. When the shielding member is deformed by a downward force, the passage area of the first passage or the second passage is reduced.

  According to the sixth saddle type vehicle seat of the present invention, when a downward force is applied to the seat and the shielding member is deformed, the passage area of the first passage or the second passage connected to the vent hole is reduced. Therefore, the amount of air flowing between the inside and the outside of the space in the seat via the vent hole is reduced, the air becomes difficult to flow, and the elasticity of the seat changes. As a result, as the driver or the like sits down on the seat, it is possible to make a sense of elasticity of the seat, and to improve riding comfort.

  In order to solve the above problems, a seventh saddle type vehicle seat according to the present invention is the above-described saddle type vehicle seat according to any one of the third to sixth aspects of the present invention, wherein the shielding member is the saddle type. It is a cushion rubber for supporting the said lower board part on a vehicle, It is characterized by the above-mentioned.

  According to the seventh saddle-type vehicle seat of the present invention, it is not necessary to separately provide a shielding member by realizing the shielding member with a cushion rubber. As a result, an increase in the number of components can be prevented in realizing a structure that improves the riding comfort by changing the elasticity of the seat.

  According to the present invention, the elasticity of a seat can be changed, and a saddle type vehicle having a comfortable ride can be realized under various circumstances or according to the preference of a driver or the like.

Further, a seat rail 10 is connected to the main frame 3, and the seat rail 10 extends from the middle part in the front-rear direction of the motorcycle 1 toward the rear side. A seat 11 is attached on the seat rail 10. A vehicle body cover 12 (only the left side is shown) is attached to the left and right sides of the seat rail 10, respectively.

  2 to 4 show the sheet 11. In FIG. 2, a seat 11 is a specific example of a saddle type vehicle seat according to the first embodiment of the present invention. The front part of the seat 11 is a seat on which the driver sits, and the rear part is a seat on which the passenger sits. The seat 11 includes a seat bottom 21 as a lower plate portion attached to the motorcycle 1, a seat cushion 22 (see FIG. 7) as a cushion material provided on the seat bottom 21, and a cover that covers the seat cushion 22. A sheet skin 23 is provided.

  As shown in FIG. 4, the seat bottom 21 is formed in a plate shape by, for example, a resin material, and has a rigidity that can support a driver sitting on the seat 11 and stabilize the seating posture. Yes. The seat cushion 22 is formed in a plate shape by an elastic material such as urethane foam, and has a thickness that can give the seat 11 appropriate elasticity. The seat skin 23 is formed of, for example, synthetic leather, and covers all surfaces of the seat cushion 22 except for the surface facing the seat bottom 21 as shown in FIG. Further, the seat skin 23 is formed of a material that can prevent water penetration so that the seat cushion 22 is not wetted by rainwater even when the seat 11 is exposed to rain, for example.

  As shown in FIG. 4, the seat bottom 21 has a pair of middle cushion rubber 25 and a pair of front cushion rubber 26 for supporting the seat 11 (seat bottom 21) on the seat rail 10 with elasticity. Is attached. The pair of middle cushion rubbers 25 are disposed on the lower surface of the seat bottom 21 so as to be separated from each other in the left-right direction at an intermediate portion in the front-rear direction of the seat 11. Each middle cushion rubber 25 protrudes downward from the lower surface of the seat bottom 21, and the protruding end surface (lower surface 25 </ b> B in FIG. 10) is a seat mounting portion (FIG. 10) attached to the seat rail 10 or the seat rail 10. (Not shown). On the other hand, the pair of front cushion rubbers 26 is disposed on the lower surface of the seat bottom 21 at the front portion of the seat 11. A front locking portion 27 and a rear locking portion 28 for detachably attaching the seat 11 to the seat rail 10 are fixed to the lower surface of the seat bottom 21.

  Furthermore, a plurality (for example, four) of non-adjusting vent holes 29 are formed in the seat bottom 21. Each non-adjustable vent hole 29 is formed between a space surrounded by the seat bottom 21 and the seat skin 23, that is, a space in which the seat cushion 22 is accommodated (hereinafter referred to as “in-seat space”) and outside. The air is communicated between the inside and outside of the seat space. Each non-adjusting vent hole 29 is disposed in the front-rear direction intermediate portion of the seat bottom 21 and penetrates the seat bottom 21. Moreover, the opening area of each non-adjustment vent hole 29 is about 150 square millimeters, for example.

  FIG. 5 shows an enlarged view of the lower surface of the seat bottom 21 at the middle portion in the front-rear direction of the seat 11. FIG. 6 shows a state in which the middle cushion rubber 25 is removed from the lower surface of the seat bottom 21 shown in FIG. As shown in FIG. 6, a pair of adjustable air holes 30 are formed in the seat bottom 21. Each adjustable vent 30 communicates between the inside and outside of the seat space, and functions as a circulation mechanism that circulates air between the inside and outside of the seat space. The pair of adjustable vent holes 30 are spaced apart from each other in the left-right direction at the middle portion in the front-rear direction of the seat bottom 21 and penetrate the seat bottom 21. Moreover, the opening area of each adjustable ventilation hole 30 is, for example, about 100 square millimeters.

  Further, on the lower surface of the seat bottom 21, the position of the opening of each adjustable ventilation hole 30 substantially coincides with the position where the middle cushion rubber 25 is attached. As a result, as shown in FIG. 5, the middle cushion rubber 25 is disposed on each adjustable vent hole 30. Each adjustable vent 30 is not blocked by the middle cushion rubber 25. As will be described later, a large passage 43 and a small passage 44 are formed in each middle cushion rubber 25, and the inside and the outside of the seat space are formed in each adjustable vent 30 and each middle cushion rubber 25. The large passage 43 (or the small passage 44) communicates. Thereby, the circulation of air through each adjustable vent 30 between the inside and outside of the seat space is ensured. Further, an engagement hole 31 for attaching the middle cushion rubber 25 is formed in the seat bottom 21.

  7 to 9 show a state in which the middle cushion rubber 25 is attached to the seat bottom 21, and FIG. 10 shows a detailed structure of the middle cushion rubber 25. (1), (2), (3), (4), (5) in FIG. 10 are respectively an external perspective view of the middle cushion rubber 25, a diagram seen from above, and a diagram seen from one side in the left-right direction. It is the figure seen from the left-right direction other, sectional drawing seen from the arrow XX direction.

  Each of the middle cushion rubbers 25 blocks the opening of the adjustable ventilation hole 30 in addition to the original function of the cushion rubber that supports the seat 11 (seat bottom 21) on the seat rail 10 with elasticity. It has a function as an adjusting mechanism for adjusting the amount of air flowing through the adjustable vent hole 30. As shown in FIG. 10, each middle cushion rubber 25 is formed in a substantially rectangular parallelepiped shape by an elastic material such as rubber. The upper surface 25A of each middle cushion rubber 25 is in contact with the lower surface of the seat bottom 21, and the lower surface 25B is in contact with the seat rail 10 or the seat mounting portion attached to the seat rail 10.

  A pair of engaging portions 42 are formed on the upper surface 25 </ b> A of each middle cushion rubber 25. Each engaging portion 42 protrudes upward from the upper surface 25A. As shown in FIG. 7, each engagement portion 42 engages with an engagement hole 31 formed in the seat bottom 21. The middle cushion rubber 25 is attached and fixed to the seat bottom 21 by the engagement of each engagement portion 42 and each engagement hole 31. Even if the middle cushion rubber 25 is pulled with a weak force, the middle cushion rubber 25 is secured to the seat bottom 21. Can not be removed from. However, the middle cushion rubber 25 can be removed from the seat bottom 21 by pulling the middle cushion rubber 25 with a certain strong force to elastically deform each engaging portion 42.

  Further, as shown in FIG. 10, the pair of engaging portions 42 are disposed so as to be point-symmetric with respect to the center point of the upper surface 25 </ b> A of the middle cushion rubber 25. As a result, the middle cushion rubber 25 can be attached to the seat bottom 21 such that one side surface 25C in the left-right direction faces the left side and the other side surface 25D in the left-right direction faces the right side. It can also be attached to the seat bottom 21 so that the other side surface 25D is directed to the right side and the other side surface 25D is directed to the left side. That is, the middle cushion rubber 25 can be rotated 180 degrees in the horizontal direction to change the mounting direction.

  In each middle cushion rubber 25, a large passage 43 is formed at a portion where the upper surface 25A is in contact with one side surface 25C in the left-right direction. The large passage 43 is configured by a groove formed in a portion where the upper surface 25A and the side surface 25C are in contact with each other. On the other hand, in each middle cushion rubber 25, a small passage 44 is formed at a portion where the upper surface 25A contacts the other side surface 25D in the left-right direction. The small passage 44 is configured by a groove formed in a portion where the upper surface 25A and the side surface 25D are in contact with each other. Each of the large passage 43 and the small passage 44 is a passage through which air flowing out from the opening of the adjustable vent 30 or flowing into the opening of the adjustable vent 30 passes. The large passage 43 and the small passage 44 have different passage areas. That is, in each middle cushion rubber 25, the groove formed in the portion where the upper surface 25A contacts the one side surface 25C in the left-right direction is larger than the groove formed in the portion where the upper surface 25A contacts the other side surface 25D in the left-right direction. As a result, the passage area of the large passage 43 is larger than the passage area of the small passage 44.

  As shown in FIG. 8, the middle cushion rubber 25 is attached in a mounting direction in which one side surface 25C in the left-right direction faces leftward and the other side surface 25D in the left-right direction faces rightward (hereinafter referred to as “first mounting direction”). ), The large passage 43 of the middle cushion rubber 25 communicates with the adjustable vent hole 30. At this time, the small passage 44 does not communicate with the adjustable vent 30. As a result, the interior and exterior of the seat space between the seat bottom 21 and the seat skin 23 communicate with each other via the adjustable vent hole 30 and the large passage 43. As a result, air can be circulated between the inside and outside of the seat space. Here, since the passage area of the large passage 43 is larger than the passage area of the small passage 44, when the middle cushion rubber 25 is attached in the first attachment direction in this way, the opening of the adjustable vent hole 30 is the middle cushion. The extent of being blocked by the rubber 25 is relatively small. Specifically, the opening portion of the adjustable ventilation hole 30 is not obstructed by the middle cushion rubber 25 at all or almost. As a result, the amount of air per unit time flowing between the inside and outside of the seat space through the adjustable vent hole 30 becomes relatively large, and the inside of the seat space through the adjustable vent hole 30. It becomes easy for air to circulate between the outside and the outside. As a result, the elasticity of the seat 11 becomes an elasticity that gives the driver or passenger a soft feel.

  On the other hand, as shown in FIG. 9, the middle cushion rubber 25 is mounted in the mounting direction in which one side surface 25C in the left-right direction faces the right side and the other side surface 25D in the left-right direction faces the left side (hereinafter referred to as "second mounting direction"). The small passage 44 of the middle cushion rubber 25 communicates with the adjustable vent hole 30 when attached to the seat bottom 21. At this time, the large passage 43 does not communicate with the adjustable vent 30. Thereby, the inside and outside of the seat space communicate with each other via the adjustable vent hole 30 and the small passage 44. As a result, air can be circulated between the inside and outside of the seat space. Here, since the passage area of the small passage 44 is smaller than the passage area of the large passage 43, when the middle cushion rubber 25 is attached in the second attachment direction in this way, the opening of the adjustable vent hole 30 becomes the middle cushion. The degree to which it is blocked by the rubber 25 is relatively large. Specifically, for example, about 75% of the opening area of the adjustable vent hole 30 is blocked by the middle cushion rubber 25. As a result, the amount of air per unit time that flows between the inside and outside of the seat space via the adjustable vent hole 30 is relatively small, and the inside of the seat space via the adjustable vent hole 30 is relatively small. It becomes difficult for air to flow between the outside and the outside. As a result, the elasticity of the seat 11 becomes an elasticity that gives a hard feel to the driver or passenger.

  As described above, according to the seat 11 according to the embodiment of the present invention, the attachment direction of each middle cushion rubber 25 is between the first attachment direction shown in FIG. 8 and the second attachment direction shown in FIG. By switching at, the amount of air flowing between the inside and outside of the seat space can be adjusted, and the elasticity of the seat 11 can be changed. Thus, depending on the weight of the driver or passenger, whether there are two persons sitting on the seat 11, the magnitude of vibrations (for example, the road surface condition) generated during traveling, the driver's or passenger's preference, etc. By switching the mounting direction of each middle cushion rubber 25, the elasticity of the seat 11 can be made appropriate according to these factors or circumstances. Therefore, it is possible to realize a good riding comfort of the motorcycle 1 according to various factors or situations.

  In addition, according to the seat 11, the user (driver, passenger, etc.) can easily change the elasticity of the seat 11 only by changing the mounting direction of the middle cushion rubber 25.

  Further, according to the seat 11, the large passage 43 and the small passage 44 formed in each middle cushion rubber 25 are selectively communicated with the adjustable vent hole 30, whereby the amount of air flowing through the adjustable vent hole 30. Therefore, a good riding comfort according to various situations can be realized with a simple structure. Further, since the structure for changing the amount of air flowing through the adjustable vent hole 30 is formed in each middle cushion rubber 25, there is no need to separately add a component for changing the amount of air flowing through the adjustable vent hole 30. . Therefore, an increase in the number of parts can be prevented, and the cost of the seat 11 or the motorcycle 1 can be reduced.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. A feature of the second embodiment of the present invention is that a large passage and a small passage are formed by forming a plurality of through holes in the middle cushion rubber. Note that (1), (2), (3), (4), and (5) in FIG. 11 are respectively an external perspective view and an upward direction of the middle cushion rubber in the seat according to the second embodiment of the present invention. It is the figure seen from one side, the figure seen from the left-right direction, the figure seen from the left-right direction other, and sectional drawing seen from the arrow XI-XI direction.

  In FIG. 11, the middle cushion rubber 51 in the seat according to the second embodiment of the present invention has a seat (seat bottom) with elastic force on the seat rail, like the middle cushion rubber 25 in the first embodiment. It has both a supporting function and a function as an adjusting mechanism for adjusting the amount of air flowing through the adjustable vent by blocking a part of the opening of the adjustable vent. Similarly to the middle cushion rubber 25 in the first embodiment, the middle cushion rubber 51 is formed in a substantially rectangular parallelepiped shape by an elastic material such as rubber, the upper surface 51A is in contact with the lower surface of the seat bottom, and the lower surface 51B is the seat. A pair of engaging portions 52 are provided on the upper surface 51A in contact with a rail or the like.

  In the middle cushion rubber 51, a large passage 53 is formed between the upper surface 51A and one side surface 51C in the left-right direction. The large passage 53 is constituted by three through holes 55 penetrating between the upper surface 51A and the side surface 51C. On the other hand, a small passage 54 is formed between the upper surface 51A of the middle cushion rubber 51 and the other side surface 51D in the left-right direction. The small passage 54 is configured by one through hole 55 that passes between the upper surface 51A and the side surface 51D.

  Similarly to the middle cushion rubber 25 in the first embodiment, when the middle cushion rubber 51 is attached to the seat bottom so as to be in the first attachment direction, three pieces penetrating between the upper surface 51A and the side surface 51C are provided. Each of the through holes 55 communicates with the adjustable vent. In this case, the degree to which the opening of the adjustable vent hole is blocked by the middle cushion rubber 51 is relatively small. Accordingly, the amount of air per unit time flowing between the inside and outside of the seat space through the adjustable vent hole increases, and air easily flows between the two. As a result, the elasticity of the seat becomes the elasticity that gives the driver or passenger a soft feel.

  On the other hand, like the middle cushion rubber 25 in the first embodiment, when the middle cushion rubber 51 is attached to the seat bottom so as to be in the second attachment direction, it penetrates between the upper surface 51A and the side surface 51D. One through hole 55 communicates with the adjustable vent. In this case, the degree to which the opening of the adjustable vent hole is blocked by the middle cushion rubber 51 is relatively large. Therefore, the amount of air per unit time flowing between the inside and the outside of the seat space via the adjustable vent is reduced, and it becomes difficult for air to flow between the two. As a result, the elasticity of the seat is such that it gives a hard feel to the driver or passenger.

  Also with the sheet according to the second embodiment of the present invention having such a configuration, the same operational effects as those of the sheet 11 according to the first embodiment of the present invention can be obtained.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. The feature of the third embodiment of the present invention is that the passage area of the large passage and the small passage is reduced when the middle cushion rubber is deformed by the downward force applied to the seat. Note that (1), (2), (3), (4), and (5) in FIG. 12 are respectively an external perspective view and an upward direction of the middle cushion rubber in the seat according to the third embodiment of the present invention. It is the figure seen from one side, the figure seen from the left-right direction, the figure seen from the other left-right direction, and the sectional view seen from the arrow XII-XII direction. Further, (6) in FIG. 12 shows a state where the middle cushion rubber is deformed and the passage areas of the large passage and the small passage are reduced.

  In FIG. 12, the middle cushion rubber 61 in the seat according to the third embodiment of the present invention has the seat (seat bottom) elastic on the seat rail in the same manner as the middle cushion rubber 25 in the first embodiment. It has both a supporting function and a function as an adjusting mechanism for adjusting the amount of air flowing through the adjustable vent by blocking a part of the opening of the adjustable vent. Similarly to the middle cushion rubber 25 in the first embodiment, the middle cushion rubber 61 is formed in a substantially rectangular parallelepiped shape by an elastic material such as rubber, the upper surface 61A is in contact with the seat bottom, and the lower surface 61B is seat rail or the like. A pair of engaging portions 62 are provided on the upper surface 61A.

  In the middle cushion rubber 61, a large passage 63 is formed between the upper surface 61A and one side surface 61C in the left-right direction. The large passage 63 is configured by a through hole penetrating between the upper surface 61A and the side surface 61C, and the cross-sectional shape of the through hole is a substantially elliptical shape that is long in the front-rear direction. On the other hand, a small passage 64 is formed between the upper surface 61A of the middle cushion rubber 61 and the other side surface 61D in the left-right direction. The small passage 64 is constituted by a through-hole penetrating between the upper surface 61A and the side surface 61D, and the cross-sectional shape of the through-hole is substantially elliptical long in the front-rear direction. The passage area of the large passage 63 is larger than the passage area of the small passage 64.

  Similarly to the middle cushion rubber 25 in the first embodiment, when the middle cushion rubber 61 is attached to the seat bottom so as to be in the first attachment direction, the large passage 63 communicates with the adjustable ventilation hole. In this case, the degree to which the opening of the adjustable vent hole is blocked by the middle cushion rubber 61 is relatively small. Accordingly, the amount of air per unit time flowing between the inside and outside of the seat space through the adjustable vent hole increases, and air easily flows between the two. As a result, the elasticity of the seat becomes the elasticity that gives the driver or passenger a soft feel.

  On the other hand, similarly to the middle cushion rubber 25 in the first embodiment, when the middle cushion rubber 61 is attached to the seat bottom so as to be in the second attachment direction, the small passage 64 communicates with the adjustable vent hole. . In this case, the degree to which the opening of the adjustable vent hole is blocked by the middle cushion rubber 61 is relatively large. Therefore, the amount of air per unit time flowing between the inside and the outside of the seat space via the adjustable vent is reduced, and it becomes difficult for air to flow between the two. As a result, the elasticity of the seat is such that it gives a hard feel to the driver or passenger.

  Further, when a downward force is applied to the seat and the middle cushion rubber 61 is crushed and deformed, as shown in FIG. 12 (6), the large passage 63 (small passage 64) is also crushed and the large passage 63 ( In the small passage 64), the opening area of the opening 63A (64A) on the side surface 61C (61D) side or the passage area near the opening 63A (64A) is reduced. As a result, the amount of air flowing between the inside and outside of the seat space through the adjustable vent is reduced, making it difficult for the air to flow and changing the elasticity of the seat. As a result, the driver can feel the elasticity of the seat as it sits on the seat (feeling that the seat hardness increases as the load applied to the seat increases), thereby improving riding comfort. be able to.

  According to the seat according to the third embodiment of the present invention having such a configuration, in addition to the operational effects obtained by the seat 11 according to the first embodiment of the present invention described above, the ride comfort can be improved by generating a feeling of feeling. Further improvement can be achieved.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. Here, another specific example of the adjusting mechanism that adjusts the amount of air flowing through the adjustable vent will be described. In addition, (1) in FIG. 13 is a cross-sectional view of the sheet according to the fourth embodiment of the present invention, and (2) in FIG. 13 is a cross-sectional view of the air flow rate adjusting mechanism as seen from the direction of arrows XIII-XIII. It is.

  As shown in FIG. 13, an adjustable vent hole 74 that communicates between the inside and outside of the seat space in which the seat cushion 73 is accommodated is formed in the seat bottom 72 of the seat 71 according to the fourth embodiment of the present invention. Is formed. Unlike the case of the first to third embodiments described above, the adjustable vent hole 74 according to the present embodiment is a place different from the place where the middle cushion rubber is disposed (for example, between a pair of middle cushion rubbers, etc.) ).

  In the lower surface of the seat bottom 72, an air flow rate adjusting mechanism 81 is provided in a portion where the adjustable vent hole 74 is opened. In the center of the main body 82 of the air flow rate adjusting mechanism 81, a common passage 83 is formed which is open at the upper side, communicates with the adjustable vent hole 74, and is closed at the lower side. In addition, four selection passages 84, 85, 86, 87 that extend radially in the horizontal direction, communicate with the common passage 83 on the inner peripheral side, and open on the outer peripheral surface of the main body 82 on the outer peripheral side, are provided on the peripheral portion of the main body 82. Is formed. The selection passages 84, 85, 86 and 87 have different passage areas. A cylindrical adjustment member 88 is rotatably attached to the main body 82 on the outer peripheral side of the main body 82 and covers the outer peripheral surface of the main body 82. Furthermore, a flow hole 89 is formed in the adjustment member 88.

  When the adjustment member 88 is rotated and the flow hole 89 is made to coincide with the opening on the outer peripheral side of any of the selection passages 84, 85, 86, 87, any of the selection passages 84 with which the flow holes 89 are aligned, The adjustable vent hole 74 communicates with the outside through the flow holes 89, 86, 87 and the flow hole 89. As a result, the inside and outside of the seat space communicate with each other through the adjustable vent hole 74. Since the selection passages 84, 85, 86, and 87 have different passage areas, the opening of the adjustable vent hole 74 can be substantially viewed depending on which selection passage 84, 85, 86, 87 is matched with the flow passage 89. The degree of shielding can be changed, and the amount per unit time of the air flowing between the inside and the outside of the seat space can be changed via the adjustable vent hole 74.

  Also with the seat 71 according to the fourth embodiment of the present invention having such a configuration, it is possible to change the elasticity of the seat 71 and realize a good riding comfort in various situations.

  In addition, the following can be employed as an adjustment mechanism for changing the amount of air flowing through the adjustable vent. For example, a sliding shutter that blocks a part of the opening of the adjustable vent may be provided. Alternatively, a cushion rubber without a passage may be used as a shutter, and the amount of blocking the opening of the adjustable vent may be changed by moving the cushion rubber mounting position in the horizontal direction. Further, it is also possible to provide a mechanism for blocking a part of the adjustable vent hole in the seat, and to arrange a lever or the like for moving the mechanism on the lower surface of the seat bottom.

  The number of adjustable vents may be one or three or more in consideration of the adjustment range of the elasticity of the seat. In addition, the position where the adjustable vent hole is formed in the seat bottom is appropriately selected such as the middle, front side, and rear side of the seat in consideration of whether it is appropriate for setting / changing the elasticity of the seat. be able to.

  Furthermore, the present invention can be applied to a seat of a type in which a driver's seat and a passenger's seat (rear seat) are separated. Further, the present invention can be applied not only to a motorcycle seat but also to a bicycle seat, a tricycle seat, and the like.
