Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a motorcycle seat with a backrest, and particularly relates to a motorcycle seat with a storage backrest that allows the backrest to be stored in and out of the rear of the seat body. It is.

[Prior art and its problems] As a motorcycle seat with a backrest,
For example, as disclosed in US Pat. No. 3,850,353, there is a technique for fixing a backrest to an arm extending from a seat body frame. However, this type of seat requires a strong and heavy arm, and the frame strength of the seat body also needs to be extremely strong. Furthermore, in this conventional technology, since the backrest is always located above the seat body, there is a problem that it may actually get in the way of driving depending on the driving posture, and furthermore, the backrest is disposed above the seat body. Due to the lack of a sense of unity, there was a problem with the appearance as a motorcycle seat.

The purpose of the present invention is to provide a motorcycle seat with a stowable buttrest that allows a backrest to be easily provided as desired, provides rigidity to the support that supports the backrest, is simple in structure, and has a good appearance. do.

[Means for Solving the Problems] The basic structure of the present invention is a motorcycle seat with a storage backrest, in which the backrest is engaged with a rigid body separate from the seat body.
That is, in a motorcycle seat in which a backrest can be stored in the rear of the seat body, the backrest is slidable in the vertical direction with respect to a rigid structure separate from the seat body so that it can be freely taken in and out. It is a motorcycle seat.

[Function] In the present invention, the backrest can be stored in the rear part of the seat body, so the backrest can be installed or stored in accordance with changes in driving posture. Further, when the backrest is stored in the rear part of the seat body, the seat itself looks integrated, improving the appearance. Further, since the backrest is supported by a rigid structure separately from the seat body, the structure of the seat body itself does not have to be complicated, and the strength of the seat body can be reduced compared to the conventional one. Furthermore, as shown in the embodiments, the sliding and fixing structure of the backrest can be simplified.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

1 to 6 show a first main body embodiment.

As is clear from FIGS. 1 to 3, the motorcycle seat 2 of this example is configured such that a seat body 4 and a backrest 10 can be stored in the rear of the seat body 4, and this backrest 10 will be described later. It is constructed so that it can be moved in and out up and down by sliding on the truck bag 38, which is a rigid structure.

As shown in FIG. 3, the seat body 4 is constructed using a frame 8 as a skeleton. The frame 8 is straight from the front end to the rear end with only slight bends at the front end and rear end. Mounted on the frame 8 is a suitable cushioning material 20 made of foamed rubber, polyurethane foam, or the like. Further, the cushion material 20 is covered with a cover 22 made of vinyl chloride, for example.

As the material of the frame 8, for example, iron, plastic, etc. are used.

A rail 2 is provided on the surface of the trunk bag 38 facing the seat body 4 (the rear surface 36 side of the seat body).
6 is disposed with its opening facing toward the rear surface 36 of the seat body 4. The rail 26 serves as a guide, and extends substantially vertically upward while facing the rear surface 36 of the seat body 4. The rail 26 is also bolted to a trunk bag 38 or cowling (not shown), which is a rigid structure separate from the seat body 4, as shown in FIG.

The backrest 10, like the seat body 4, is composed of a frame 30, a cushion material 20, and a cover 22. In this embodiment, a member that fits with the guide is further provided. In this embodiment, a rail 28 is provided as such a member. rail 28
is built into the backrest 10, but it may also be provided outside the backrest 10.

The backrest 10 is attached to the trunk bag 38 by fitting the rails 28 and 26 so as to be slidable in the vertical direction.

The height of the backrest 10 can be adjusted by providing known locking mechanisms on the rails 26, 28. As an example of this, in this embodiment, it is performed as follows. As shown in FIG. 5, a pair of holes 4 are provided at the same height on both sides of the rail 28.
Set 0. A compression spring 44 is inserted into the hole 40.
A pair of engaging members 46 that are connected via a pair of engaging members 46 are fitted together. On the other hand, as shown in FIG. 5b, the rail 26 is provided with a plurality of engagement holes 42 (four pairs in this example) arranged in pairs having the same height at a predetermined interval. When the backrest 10 is slid in the vertical direction and the hole 40 and the engagement hole 42 become coaxial, the engagement member 46 is fitted into the engagement hole 42, and the backrest 10 is supported at a predetermined height. At this time, the compression spring 44 fits into the hole 42 and is sufficient to maintain the position of the backrest 10.
0 can be easily removed from the hole 42 in order to slide it in the vertical direction.

At the rear of the trunk bag 38, a lid 50 is hinged to the trunk bag 38 at its upper end. An engagement molding 54 that engages with the trunk bag 38 is provided at the lower end of the lid 50.

7 and 8 show a second embodiment.

In this embodiment, the distal end 62 of the carrier 60 is bent upward and erected to face the rear surface 36 of the seat body 4. This upright carrier tip 62 serves as a guide.

A cylindrical space 64 having substantially the same cross-sectional shape as the carrier tip 42 is provided inside the backrest 10 .

The carrier tip 62 is inserted into the cylindrical space of the backrest 10, and the backrest 10 is attached so as to be slidable in the vertical direction. In this case, back crest 10
is fixed at any position to the carrier tip 62 by the friction of its own cushioning material. Alternatively, other known mechanical engagement methods may be used.

Note that instead of providing the cylindrical space 64 inside the backrest 10, a member that can fit with the carrier tip 62 may be provided outside the backrest 10 to allow the backrest 10 to slide. The locking method in this case can be easily accomplished by employing known mechanical means.

As described above, since the frame of the seat body is not used for sliding the backrest, it is possible to provide a motorcycle seat with a backrest that can be constructed lightweight without making the seat body too large. Moreover, since it is stored at the rear of the seat body, if this storage is possible, the shape of the seat body can be changed, and a wide variety of motorcycle seats can be provided in small quantities.

[Effects of the invention] Since the present invention is constructed as described above, the backrest can be stored in the rear part of the seat body.
It can be stored and has sufficient rigidity. Furthermore, when the backrest is stored in the rear part of the seat body, the seat looks integrated, and the appearance can be improved. Since the sliding storage structure of the backrest is made separate from the seat body, the seat can be manufactured at low cost without complicating the structure.
