Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-wheeled motor vehicle C2 in which a seat pack supporting the rear part 22 of the seat and the driver's back or lower back is movable in the front and rear directions.

When traveling long distances on a motorcycle, driving becomes easier if a seat pack is provided at the rear of the seat to support the driver's back or waist. Conventionally, this seat back has been fixed to the rear of the seat, or as shown in Japanese Utility Model Publication No. 57-36536 (2), it is movable in the front-rear direction to accommodate different driver preferences and body shapes. It is known that it was set up in

By the way, when the above-mentioned seat puncture is provided in a motorcycle having a low seat height and an up handle that is narrowed toward the driver's side so that the seat can be fully moved, the driver's driving posture is tilted backwards in this type of motorcycle, so the driver cannot move the seat easily. It will be in a state where it is leaning against the puck. Therefore, the load applied not only to the seat back but also to its supporting portion becomes large, but the support structure of the conventional seat back has insufficient support strength and is problematic in terms of strength.

The present invention has been made based on these circumstances, and it is possible to provide a seat pack that is movable in the front-back direction (= movable). The aim is to provide motorcycles that can.

In other words, in order to achieve the above object, the present invention provides guide rails extending along the front and back direction on the left and right seat rails, respectively, and also fixes the guide rails at two points spaced apart in the front and back direction.

Features.

The present invention will be explained below based on an embodiment shown in the drawings.

Number 1 in the figure is the backbone-shaped frame that makes up the vehicle body. - Right and left seat pillar tubes 3, 3 that extend downward are welded to the rear end of the turn section 2, and in the middle of these seat pillar tubes 3, 3, there are welded seat pillar tubes 3, 3 that extend rearward approximately horizontally. Left and right seat rails 4, 4
The front end is welded. In FIG. 1, 5 indicates a front fork, 6 indicates an engine, 7 indicates an air cleaner case shaped like a fuel tank, and 8 indicates a handle.

The first half of the 'y-trails 4, 4 is located much lower than the y-yy-n part 2, and the seat 9 is placed on this front half, so that the height of the 7-trail 9 is set low. has been done. A seat pack 1θ (backrest) that supports the back of the driver A is provided at the rear of the seat 9 so as to be movable in the front-rear direction. Details of the seat pack 10 and support structure are shown in FIGS. 2 and 3. That is, 1 is a support frame made of bent wood, and a cushion 12 is attached to the front surface of this support frame 11. Support stays 14.14 constituting left and right mounting portions are bolted to brackets 13, 13 welded to the left and right lower ends of the support frame 11, respectively, and these support stays 14.14 extend forward. and is located outside the seat rails 4, 4. Furthermore, brackets 15.15 and support base ribs 16.16 extending downward are welded to the lower surfaces of the front half of the seat rails 4, 4, respectively, spaced apart in the front-rear direction. Left and right guide rails 17, 17 are fixed via delts 18 and nuts 19 between these brackets 15, 15 and the support grooves 16°16. , 4 and extends in the front and rear directions. GA・F TRAIL 17.1
7 has guide portions 20° 21 extending inwardly over its entire length on its upper and lower edges, and grooves 22 opening on both left and right sides.
It houses 8 heads. Idolrail 17 like this
．． Slide members 23 and 23 are fitted into each of the slide members 17 so as to be slidable in the front-rear direction. The slide members 23.23 are press-molded metal plates, and are elongated in the front-rear direction, and have a U-shaped cross section. This slide member 23.23 is placed over the outside of the idle rail 17.17, and a fitting portion 2 is provided continuously on the upper and lower edges of the slide member 23.23.
4, 25 are the guide parts 20, 2 of the idle rails 17, 17

is polymerized, and delt 2 is formed at two locations spaced apart in the front-back direction.
6 and a nut 27. In this case, the nut 27 is housed in the groove 22.

Further, one slide member 23 is provided with a stopper mechanism 28 for determining the sliding position of the seat pack 10. That is, as shown in FIGS. 4 to 6, a plurality of positioning holes 28 are formed at equal intervals in the front-rear direction in the lower guide portion 2 of the guide rail 1z. At the same time, the slide member 23 is provided with a pin 30 that is removably engaged with one of the positioning holes 28 through a bracket 29. is biased in the direction of engagement. Therefore, if the bin 30 is pulled out downward, it will be disengaged from the positioning hole 28, so the seat pack 10 can be slid in the front and back direction via the stay 41 members 23, 23, and the position of the seat pack 10 can be adjusted by the driver. You can change it according to your physique and preferences.

According to such a configuration, since the support stays 14.14 of the seat pack 10 are fixed to the slide member 23.2'3 at two locations spaced apart in the front-rear direction, the load of the driver A is applied to the seat pack 10 during driving. Even when the sliding member 23°23° receives the load at two places spaced apart from each other, the load is distributed and the force applied to each fixed point can be reduced. Moreover, since this slide member 23.23 itself has an elongated shape along the front-rear direction, the contact area with the guide rail 17.17 increases, and the slide member 23.2
The load applied to 3 can be received over a wide area. Therefore, there is no possibility that the load will be concentrated locally, and even if the seat pack 10 is slidable, it can be firmly supported.

Further, in this embodiment, the seat pack 10 can be slid back and forth by simply pulling out the pin 30 downward, which has the advantage of being easy to use.

Note that the present invention is not limited to the embodiments described above. For example, in the above embodiment, the left and right support frames provided on the seat pack were fixed to the slide member at two locations, front and back.
If more strength is required, it may be fixed at three or four locations.

Moreover, the stone 12 mechanism is not limited to the above-mentioned embodiment, for example, a slide member may be used. The tightening may be fixed to the guide rail using a bolt or the like.

According to the present invention described in detail above, guide rails extending along the front and rear directions are provided on the left and right seat rails, and an elongated slide member is attached to the guide rails so as to be slidable in the front and rear direction. Since the left and right mounting portions of the seat pack are fixed at at least two locations spaced apart in the longitudinal direction, the driver's load applied to the slide member due to a seat puncture can be distributed and borne at each fixing point. Since the contact area between the slide member and the idle rail increases, the load applied to the slide member can be received over a wider area, and therefore the load is not concentrated locally, which has the advantage of improving the support strength of the seat pack.
