Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a two-person saddle type seat for a motorcycle.

(Prior Art) A seating arrangement for two people, which is made of a front seat and a rear seat connected together and made of an elastic material such as urethane foam, is known in the art, in which a rising part is formed on the rear seat, which is an integral extension of the front and rear seats, and which is inclined and rises with a slight arc, and which is fixed in position for the front and rear and is at a height sufficient to support the lower back.
Japanese Utility Model Publication No. 82962 shows a structure in which a backrest is provided at the rear of a seat so that it can be raised and lowered. Japanese Utility Model Publication No. 7-3505 shows a structure in which a support is erected at the rear of a saddle and a backrest that can be moved up and down is attached to the support. Japanese Utility Model Publication No. 47-3393 shows a structure in which a backrest that can be moved up and down is provided on the back pillar of a chair.

(Problems to be Solved by the Invention) The backrest of the two-person motorcycle saddle type seat described in the above-mentioned Japanese Utility Model Application Publication No. 53-82962 cannot be adjusted up and down. Further, the backrest disclosed in the above-mentioned Japanese Utility Model Publication No. 7-3505 has a structure in which the support is fixed and only the backrest moves up and down, so the upper end of the support may protrude in some cases, making it unusable for motorcycles. Further, the same applies to the one disclosed in Japanese Utility Model Publication No. 47-3393.

(Means for Solving the Problem) Therefore, the present invention integrates this into the rear seat of the two-seater seating section 3, which is made of an elastic material such as urethane foam and which is connected to the front seat and rear seat. A rising part 4 is formed which stands up in an inclined shape with a slight arc in a state of extension, and this rising part 4 has a front-rear immovable structure and has a height that supports the waist. A two-person motorcycle saddle type seat is provided with a vertically movable stay 7 and a lumbar support 6 for supporting the waist or back of the rider.

(Embodiment) To explain with reference to the drawings, 1 is a motorcycle body, 2 is a saddle type seat for two people, and 3 is a seating part, on which the rider sits astride. Thus, the rear seat of the seating section 3 forms an upright section 4 that extends integrally. The rising portion 4 raises the rear part of the rear seat in an inclined manner with a slight arc. The inside of the rising part 4 is made of an elastic material such as urethane foam, and its surface extends and surrounds the skin of the seating part 3. A seat frame (made of iron plate, hard resin, etc.) of the seating section 3 is extended and attached to the upright section 4 to maintain its shape.

A stay 7 is attached to the upper part 5 of the upright part 4 so as to be able to move up and down, and a lumbar support 6 is attached to the stay 7. The lumbar support 6 has a frame surrounded by an elastic material, and an outer surface of the lumbar support 6 surrounded by a skin like the seating part 3. The lumbar support 6 abuts against the waist or back of a passenger sitting on the rear seat of the seating section 3, and supports the lumbar support without moving rearward when the lumbar support 6 makes contact with the waist or back. Moreover, the lumbar support 6 is formed so that its height position can be adjusted up and down.

Figures 6 to 9 show an example of a vertical adjustment mechanism for the lumbar support 6, in which a plate spring-shaped stay 7 is inserted into and out of the vertical tube embedded in the upper part 5 of the upright part 4 from above. However, a protrusion formed on a part of the spring body 8 is adapted to be engaged with the engagement hole formed at a predetermined interval in the length direction of the stay 7.

FIG. 10 shows a projection 1 attached to the tip of a leaf spring 10 on a cylinder provided on the rear side of the upper part 5 of the upright part 4.
1 is provided so as to elastically protrude into the cylinder, and a round bar-shaped stay 7 is fixed to the lumbar support 6.
The stay 7 is inserted from above, and the stay 7 is provided with recesses 9 at predetermined intervals in the length direction.
The lock pin 11 is selectively engaged with the lock pin 11.

FIG. 11 shows a vertical movement device using a combination of a rack 12 and a pinion 13.

(effect) Next, we will discuss the effect.

Since the present invention has the above-mentioned configuration, the driver in the front seat operates the vehicle by holding the steering wheel, and the passenger in the rear seat sits by holding the grip formed at a desired position.

Although the rear passenger is unstable in the longitudinal direction compared to the driver, since the lumbar support 6 is provided at the upper part 5 of the upright part 4 of the present invention, the lumbar or back can be supported reliably. can. In addition, the height of the lumbar support 6 can be adjusted vertically, so by moving the lumbar support 6 up and down depending on the seating condition of the rear seat, the lumbar support 6 can be adjusted to fit the waist or back in an optimal state. Since they are supported next to each other, you can ride with them with less fatigue. In this case, since the vertical adjustment of the lumbar support 6 is performed together with the stay 7, the stay 7 does not protrude upward, making it suitable for motorcycle use.

(Effects) As mentioned above, conventionally, a front seat and a rear seat made of an elastic material such as foamed urethane are integrally extended to the rear seat of a seating area for two people. It is known that a raised part is formed in an inclined manner with a slight arc, and the raised part has a structure that does not move forward and backward, and has a height that supports the waist. Further, Japanese Utility Model Publication No. 53-82962 discloses a configuration in which a backrest is provided at the rear of the seat so that it can be raised and lowered. Further, Japanese Utility Model Publication No. 7-3505 shows a structure in which a support is erected at the rear of the saddle, and a backrest that is movable up and down is attached to the support. Also, Mikiaki
47-3393 discloses a structure in which a backrest of a chair is provided with a vertically movable backrest. However, the backrest of the two-person saddle-type motorcycle seat described in the above-mentioned Japanese Utility Model Application Publication No. 53-82962 cannot be adjusted up and down. Further, the backrest disclosed in the above-mentioned Japanese Utility Model Publication No. 7-3505 has a structure in which the support is fixed and only the backrest moves up and down, so the upper end of the support may protrude in some cases, making it unusable for motorcycles. Further, the same applies to the one disclosed in Publication of Utility Model Publication No. 47-3393.

However, in the present invention, a slight arc is formed by integrally extending the rear seat of the two-seater seating section 3, which is made of an elastic material such as urethane foam and has a front seat and a rear seat connected to each other. A rising part 4 that stands up in an inclined manner is formed, and the rising part 4 has a structure that is immovable in the front and back and has a height that supports the waist.A stay 7 that can move vertically is provided at the top of the rising part 4, Since the stay 7 is configured as a two-person motorcycle saddle type seat with a lumbar support 6 that supports the waist or back of the rider, the lumbar support 6 prevents the passenger from being unstable in the longitudinal direction. The lumbar support 6 can reliably support the waist or back of the rider, and when the lumbar support 6 is moved up and down depending on the seating condition of the rear seat, the stay 7 can be adjusted together, making it suitable for motorcycles without the stay 7 protruding upward. It has the effect of becoming.
