JP 2001-71795 A

  Conventionally, in such a motorcycle, the rigidity of the cushion pad of the seat is generally set to a relatively high value in consideration of stability during driving.

  However, when the motorcycle is stopped, the operator overhangs both feet or one of the feet, and the thighs on the landing side are in contact with both sides of the cushion pad, which is relatively rigid. As a result, the cushion pad makes the thigh feel somewhat uncomfortable.

  The present invention has been made in view of such circumstances, and when the driver stops, when the operator overhangs and lands on both feet or one side, the seat does not give the driver's thigh a sense of incongruity. An object is to provide a straddle-type vehicle.

  In order to achieve the above-mentioned object, the present invention relates to a seating of the cushion pad in a straddle-type vehicle in which a straddle-type seat comprising a seat bottom plate and a cushion pad placed on the seat bottom plate is mounted on a vehicle body. A low-rigidity part is provided on the left and right sides of the part, inside the repose part where the thighs of the landing pilot's foot come into contact when the vehicle is stopped, making the inward rigidity of the repose part lower than that of other parts. Is the first feature.

  In addition to the first feature, the second feature of the present invention is that the low-rigidity portion is configured by a space without the cushion pad material.

  In addition to the first feature, the present invention further includes a leg grip portion at the front end portion of the cushion pad that is higher in rigidity than the repose portion and is clamped between the left and right thighs of the operator when traveling. This is the third feature.

  Furthermore, the present invention provides, in addition to the first feature, that a flexible wall having lower rigidity than the other part of the sheet bottom plate is provided in a portion corresponding to the low rigidity portion of the sheet bottom plate. Features.

  Furthermore, in addition to the first feature of the present invention, a side cowl supported by the vehicle body is disposed below the seat, and on the outer side surface of the side cowl, the foot of the operator who is landing when the vehicle is stopped. A fifth feature is that a recess for receiving the inner part of the thigh is provided.

  In addition to the fourth feature of the present invention, in addition to the fourth feature, the seat bottom plate is formed with a downward flange that is connected to the outer end of the flexible wall and supports the inner surface of the lower end of the repose portion. A side cowl supported by the vehicle body is disposed below, and an upward flange facing the inner surface of the downward flange with a predetermined gap is formed on the side cowl. And

  According to the first feature of the present invention, when the operator stops the foot when the operator stops, the thigh of the foot inevitably comes into contact with the rest of the cushion pad. The inward stiffness is set lower than the stiffness of the other parts, so that the resting part bends smoothly inward with the thigh contact, and does not give the thigh a sense of incongruity, The landing property of the foot can be improved.

  According to the second feature of the present invention, in order to make the inward rigidity of the rest portion lower than the rigidity of other portions, a low-rigidity portion made of a void is provided inside the rest portion. The place can be formed simultaneously with the molding of the cushion pad, and does not incur a high cost.

  According to the third feature of the present invention, when the operator holds the leg grip portion 13c at the front end portion of the cushion pad with both knees during normal running, the leg grip portion 13c is more rigid than the inward rigidity of the rest portion. Since high rigidity is given, the clamping force of the leg grip part 13c by both knees can be increased, and the steering posture can be stabilized.

  According to the fourth aspect of the present invention, the flexible wall of the seat bottom plate bends along with the inward deflection of the rest portion, so that the seat bottom plate allows the inward deflection of the rest portion. Thus, it is possible to ensure a contact state without a sense of incongruity with the rest of the thigh.

  According to the fifth aspect of the present invention, when the vehicle stops, the inner part of the thigh of the landing pilot's foot is received by the concave part 18 on the outer surface of the side cowl, so that the thigh and the side cowl interfere with each other. Can be avoided, and the landing property of the foot can be improved.

  According to the sixth aspect of the present invention, since the side cowl has an upward flange facing the inner surface of the downward flange of the seat bottom plate, the seat and the side cowl can be seen continuously in a side view. Make it better. Moreover, since the upward flange is arranged at a certain distance from the downward flange to the inside thereof, the downward flange is prevented from interfering with the upward flange when the inward portion is bent. In addition, it is possible to ensure a smooth deflection toward the inside of the rest portion.

The side view of the straddle-type vehicle which concerns on embodiment of this invention. FIG. FIG. 3 is a sectional view taken along line 3-3 in FIG. 2. The perspective view of the sheet | seat and side cowl in FIG. FIG. 3 is an operation explanatory diagram of the present invention corresponding to FIG. 2. FIG. 3 is a view corresponding to FIG. 2 showing another embodiment of the present invention.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  First, in FIG. 1, a motorcycle M as a straddle-type vehicle includes a front fork 2 that pivotally supports a front wheel 1f, a vehicle body 3 that supports the front fork 2 by a head pipe 3a at a front end, and the vehicle body The rear fork 4 is supported at the rear end of the rear wheel 3 so as to be vertically swingable, and supports the rear wheel 1r at the rear end, and the engine 5 is attached to the vehicle body 3 and drives the rear wheel 1r. On the vehicle body 3 directly above the engine 5, a fuel tank 6 and a straddle-type seat 7 disposed immediately after the fuel tank 6 are mounted. A pair of left and right side cowls 8 that are supported by the vehicle body 3 are disposed directly from both sides of the fuel tank 6 to the seat 7. The side cowl 8 is disposed so as to cover the outer surface of the accessory of the motorcycle M, such as the intake system 9 of the engine 5. A pair of left and right steps 10 are attached to the lower part of the vehicle body 3 in the vicinity of the engine 5.

  As shown in FIGS. 2 to 5, the straddle-type seat 7 covers a seat bottom plate 12 attached to the vehicle body 3, a cushion pad 13 placed on the upper surface of the seat bottom plate 12, and the cushion pad 13. Then, the terminal is constituted by the skin 14 fixed to the seat bottom plate 12.

  The sheet bottom plate 12 is made of hard synthetic resin, and is injection-molded using, for example, polypropylene. The cushion pad 13 is formed of a flexible foam material such as urethane foam, PP foam, or PE foam, and PVC leather, artificial leather, natural leather, or the like is used for the skin 14.

  The cushion pad 13 includes a seat portion 13a that supports the buttocks Ra of the operator R straddling the cushion pad 13 and the thighs of the feet of the operator R that land when the vehicle is stopped. There is a repose portion 13b that is in contact with Rb, and a leg grip portion 13c that is located in front of the seating portion 13a and is sandwiched between the left and right thigh portions Rb of the operator R when traveling, Is provided with a void 15 as a low-rigidity part that makes the inward rigidity of the rest part 13b lower than the rigidity of other parts. The material of the cushion pad 13 does not exist in the space 15. The void 15 extends beyond the rest portion 13b while opening its lower surface, and extends in the front-rear direction. In this way, when the thigh Rb of the pilot R is in contact with the repose 13b, the repose 13b can be bent inward without giving the thigh Rb a sense of incongruity.

  Further, the rest portion 13b is gently curved outwardly and downward from the seating portion 13a, and the lower end portion thereof extends slightly downward from the seating portion 13a. By doing so, the contact of the pilot R with the repose part 13b of the thigh Rb can be made more uncomfortable.

  The void 15 does not extend to the location of the leg grip portion 13c. Accordingly, the rigidity of the leg grip portion 13c is higher than the rigidity of the rest portion 13b, similarly to the seating portion 13a.

  The seat bottom plate 12 includes a main wall that supports the lower surface of the seating portion 13a, a flexible wall 12b that extends from both ends of the main portion 12a and faces the space 15, and an outer end of the flexible wall 12b. And a downward flange 12c that supports the inner surface of the lower end portion of the repose portion 13b. A plurality of ribs 17 extending in the front-rear direction are integrally formed on the lower surface of the main wall in order to enhance its rigidity. The flexible wall 12b is formed thinner than the main wall and the downward flange 12c so as to be able to bend at the same time as the inward bending of the rest portion 13b.

  The side cowl 8 is directly below the side portion of the seat 7 and is continuous with the side surface of the cowl body 8a having a U-shaped cross section that opens toward the inside of the vehicle body 3, and rises from the upper end of the cowl body 8a. The upper flange 8b is opposed to the inner surface of the downward flange 12c of the seat bottom plate 12, and the upward flange 8b is disposed from the downward flange 12c to the inside thereof with a constant gap g. .

  In addition, a concave portion 18 is formed on the outer surface of the cowl body 8a to receive the inner portion of the thigh Rb of the foot of the pilot R landing when the vehicle stops.

  In addition, as shown in another embodiment of FIG. 6, the space 15 can be filled with an auxiliary pad 20 having a lower rigidity than the material of the cushion pad 13 to adjust the rigidity of the low rigidity portion. The auxiliary pad 20 is the same as the material of the cushion pad 13, but a material having a higher foaming rate is used, or a flexible material different from the cushion pad 13 is used.

  Next, the operation of the above embodiment will be described.

  As shown in FIG. 5, when the driver R stops the motorcycle M while driving, both the feet or one foot removed from the step 10 in a state of straddling the seat 7 are projected outward and landed. . Then, the thigh Rb of the foot inevitably comes into contact with the repose portion 13b of the cushion pad 13, but the inward rigidity of the repose portion 13b is set lower than the rigidity of other portions. The rest portion 13b bends smoothly inward with the contact of the thigh Rb, and not only does not give the thigh Rb a sense of incongruity but also improves the landing property of the foot.

  Moreover, in order to make the inward rigidity of the rest part 13b lower than the rigidity of other parts, a low-rigidity part consisting of the void 15 is provided inside the rest part 13b. 13 can be formed at the same time as molding, and the cost is not increased.

  Further, since the seat bottom plate 12 on which the cushion pad 13 is placed is provided with a flexible wall 12b facing the space 15, the flexible wall 12b is also bent along with the inward bending of the rest portion 13b. Thus, the seat bottom plate 12 allows the inward bending of the repose portion 13b, and a contact state without a sense of incongruity with the repose portion 13b of the thigh Rb can be ensured.

  Further, since the recess 18 for receiving the inner side of the thigh Rb of the landing foot is provided on the outer surface of the side cowl 8 that continues below the resting portion 13b, interference between the thigh Rb and the side cowl 8 occurs. Can be avoided, and the landing property of the foot can be improved.

  By the way, the side cowl 8 has the upward flange 8b facing the inner surface of the downward flange 12c of the seat bottom plate 12, so that the seat 7 and the side cowl 8 can be seen continuously in a side view. Make good. In addition, since the upward flange 8b is arranged at a certain distance g from the downward flange 12c to the inside thereof, the downward flange 12c is in contact with the upward flange 8b when bent inward of the repose portion 13b. Can be prevented, and smooth deflection inward of the rest portion 13b can be ensured.

  In the normal running of the motorcycle M, the operator R puts both feet on the step 10 while bending both knees. At this time, the operator R holds the leg grip portion 13c at the front end of the cushion pad 13 between the thigh portions Rb. By the way, in the cushion pad 13, since the leg grip part 13c other than the rest part 13b, in particular, the normal rigidity higher than the inward rigidity of the rest part 13b is given, the leg grip part 13c is sandwiched between the thigh parts Rb. The power can be increased, which can contribute to the stabilization of the steering posture.

  The present invention is not limited to the above embodiment, and various design changes can be made without departing from the scope of the invention. For example, the present invention is not limited to the motorcycle M but can be applied to other straddle-type vehicles such as a tricycle and a buggy.
