Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a side support provided on a seat of a motorcycle, etc., and particularly to a side support formed into a unit.

[Prior Art] Some motorcycles have a seat equipped with a side support device. This side support device consists of a pair of side support plates that are pivotably attached to the bottom plate of the seat so that they can be expanded, and an adjustment mechanism for adjusting the expansion of the side support plates is attached to the bottom plate of the seat separately. be.

[Problems to be Solved by the Invention] In the above case, the side support plate and the adjustment mechanism are each separately attached to the bottom plate of the seat, etc., so if the mechanisms to be attached are different, the shape of the seat and the structure of each part may be affected. , especially the bottom plate etc. are often different. Therefore, the dimensions of the mounting portion, the mounting structure, etc. had to be redesigned each time the model changed, and in the end, it was necessary to manufacture a new side support device for each model. Therefore, the more other types were produced in small quantities, the more disadvantageous they became in terms of price, etc. Furthermore, when the need for repair or replacement arises during use, almost the entire sheet must be disassembled before work can be carried out, which is inconvenient.

Therefore, in order to solve these problems, the present invention aims to provide a side support device that is versatile even between different models and is easy to repair and replace. [Means for solving the problems] The side support device of the present invention has the following configuration.

That is, a support member extending in the left-right direction of the seat, a pair of side support plates supported so as to be expandable at both ends of the support member, and an adjustment mechanism for adjusting the expansion of the side support plates are integrated into a unit. It is characterized by

[Operation of the Invention] In the side support device of the present invention, the side support plate and the adjustment mechanism are integrated into a unit.

Therefore, the side support device is attached to the seat by processing only a portion of the seat bottom plate in the area where the side support device is to be attached to form an attachment portion, and attaching the side support to the attachment portion. Moreover, if the side support unit is removed from the bottom plate side while the side support device is attached, the side support device can be quickly separated from the seat.

[Example 1] Figures 1 to 5 show an example in which the present invention is applied to a motorcycle seat.

FIG. 1 shows a motorcycle seat S to which the present invention is applied. This seat S is a two-person seat, and has a front seat Sf and a rear seat Sr. However, the front seat Sf and the rear seat Sr are manufactured as separate structures, and when each is mounted on a vehicle body frame (not shown), the seat S is integrated. Between the front seat Sf and the rear seat Sr is a backrest sb that is separate from both.
is provided. A pair of side pads Ss projecting forward (to the left in the figure) are provided on both sides of the backrest sb to support the lumbar region of the occupant. Further, a side support unit 1 is built into the backrest sb, and side support plates 2a and 2b are provided at both ends of the side support unit 1 so as to be expandable.

A knob 3 is fixed to the side of the front seat Sf below the backrest sb. Knob 3 is side support plate 2a/2
This is to adjust the amount of expansion of b.

FIG. 2A shows the constituent parts of the sheet S in an exploded manner. That is, the seat S consists of a front seat Sf, a rear seat Sr, and a backrest sb, which are each manufactured separately, and the side support unit 1 is built into the backrest sb. The rear part of the front seat Sf forms a backrest attachment part 4. A backrest sb is detachably attached to this portion. The front part of the rear seat Sr is formed along the back surface of the backrest sb, and a bracket 5 for attaching the rear seat Sr to the vehicle body frame is provided at the lower part of the interior thereof.

The side support unit 1 has a box-shaped support member 6 having a width in the lateral direction of the seat S, and a pair of side support plates 2a and 2b that are expandably attached to both sides of the support member 6. An adjustment mechanism M is built-in. The amount of expansion of the side support plates 2a and 2b is adjusted by an adjustment mechanism M. Further, mounting protrusions 8 are provided on the upper and lower sides of the support member 6.

FIG. 3 shows the structure of the side support unit 1. This side support unit 1 is provided with a box-shaped support member 6 having a U-shaped cross section, and a rotary drive member 9 is rotatably attached to the wall portion of this support member 6. The tip of the rotational drive member 9 enters the support member 6 and is integrated with the bevel gear 10. Bevel gears 11 and 12 are disposed in mesh with the bevel gear 10 so as to face each other. The bevel gear 11 is a rotating shaft 13

is formed, and its tip is rotatably supported by the wall portion 15.

An ohm wheel 16 meshes with the ohm 14, and the ohm wheel 16 is fixed to the tip of the side support plate 2a and rotatably attached to the shaft 17. On the other hand, the bevel gear 12 is connected to one end of a rotating shaft 18 , and the other end of the rotating shaft 18 is fitted into one end of a joint vibrator 19 . One end of a shaft 20 is also fitted to the other end of the joint pipe 19, and these are connected to screws 21 and 22.
are integrally connected by fastening. A ohm 23 is formed at the other end of the shaft 20, and its tip is rotatably supported by a wall 24. Ohm wheel 2 on Ohm 23
5 are in mesh with each other, and the ohm wheel 25 is fixed to one end of the side support plate 2b and is rotatably attached to the shaft 26. Note that the ohms 14 and 24 are arranged so that their teeth are in the same direction. Therefore, when the rotary drive member 9 is rotated in the direction of arrow A, the bevel gear 10 also rotates in the direction of A, and the bevel gears 11 and 12 that mesh with this rotate in the opposite direction in the directions of arrows B and C, respectively. As a result, the ohm wheel 16 meshing with the ohm 14 rotates the integrated side support plate 2a in the direction of the arrow. At the same time, do the same on the side support plate 2b side as shown by arrow E.
rotate in the direction. As a result, the space between the side support plates 2a and 2b is narrowed, and the lumbar region of the occupant is strongly supported. Conversely, if the distance between the side support plates 2a and 2b is widened to weaken the support for the occupant's waist, the rotational drive member 9 may be rotated in the opposite direction.

FIG. 4 shows the installed state of the side support unit 1.

The support member 6 of the side support unit 1 is attached to the bottom plate 7 of the backrest sb through mounting protrusions 8 (see Figure 2A) and bolt holes 8a, 8b, 8C and 8d (see Figure 2B).
It is bolted 27 at. At this time, the lower end of the bottom plate 7 is rotatably attached to the tip of a bracket B of a slide and reclining mechanism, which will be described later. In this embodiment, since the unit 1 is attached to the back side of the bottom plate 7,
Even if the inside of the backrest sb is made of only a cushioning material such as polyurethane foam, and this is simply covered with a suitable skin, this is an extremely advantageous structure because the occupant's back does not feel the hardness of the unit 1. A transmission cable 28 connected to the bevel gear 1o passes through the bottom of the rear seat Sr, enters the vehicle body frame below the rear seat Sr, and reaches the knob 3. The knob 3 is disposed on the side of the vehicle within a range that can be operated by occupants in the front seat Sf and the rear seat Sr. This knob 3 is integrated into the housing 29. A gear mechanism (described later) for rotating the knob 3 is built into the housing 29, and is transmitted to the side support unit 1 via a transmission cable 28 or the like. Also, from the knob 3, together with the transmission cable 28,
Transmission cables 30 and 31 are provided, which are connected to the reclining mechanism and the sliding mechanism, respectively.

The rotational force of the knob 3 can be switched to the transmission cable 28.30 or 31, respectively, and is selectively transmitted via the transmission cable 28.30 or 31 to the respective mechanism. These transmission cables are flexible and consist of a steel cable 32 capable of transmitting rotation applied to one end to the other end, and a resin pipe 33 covering the cable.

FIG. 5 shows the gear mechanism within the knob 3 and housing 29. The knob 3 consists of dials 34 and 35 coaxially and rotatably mounted. A gear 36 that rotates concentrically and integrally is provided on the dial 34, and the gear 36 meshes with a large-diameter transmission gear 37. The gear 37 is provided with a concentric gear 38 having a small diameter, and the gear 38 meshes with the gear 39. The gear 39 is integrated with a bevel gear 40. However, in the figure, bevel gear 40 is on top, and gear 39 is on top.
cannot be seen because it overlaps underneath it. A bevel gear 41 is meshed with the bevel gear 40. bebel gear 41
is integrally connected to the end of the cable 32 of the transmission cable 28. The gears 36, 37, and 38 are integrated with the dial 35, and rotate concentrically with the rotation of the dial 35. A gear 39 and similar gears 42 and 43 are disposed at a meshing position on the rotating orbit of the gear 38. The dial 35 has a selector 44, and by adjusting the selector 44, the gear 38 can be switched to mesh with either the gear 39, 42 or 43. gear 42
・43 is connected to the knob 3 by a mechanism similar to the transmission cable 28.
The transmission cables 30 and 31 mesh with bevel gears (not shown) fixed to the ends, so that rotation can be transmitted to the respective drive parts. Dials 34 and 35, each gear, and transmission cables 28 and 30
and 31 etc. are attached to the housing 29.

Then, by turning the dial 35 of the knob 3, the position of the selector 44 is selected, the gears 38 and 39 are engaged, and the connection state with the transmission cable 28 is switched. Thereafter, the dial 34 is rotated clockwise or counterclockwise. Then,
Dial 34 → Gear 36 → Gear 37 → Gear 38 → Gear 3
9 → Bebel gear 40 → Bebel gear 41 and dial 3
4 rotations are transmitted. As a result, the steel cable 32 of the transmission cable 28 integrated with the bevel gear 41 is also rotated, and the bevel gear lO (fourth
(see figure) is also rotationally driven. As a result, Bebel gear 1
0 rotates the bevel gears 11 and 12, respectively, and can expand or close the side support plates 2a and 2b as described above.

Note that in this embodiment, the front seat Sf, the rear seat Sr, and the backrest sb are each configured separately, so that they can be arbitrarily combined. In addition, when manufacturing two types of side support unit l, one with and without one, it is only necessary to attach or not attach unit 1 to backrest sb, so it is easy to manufacture multiple types with different specifications. products can be manufactured. Furthermore, if repair or replacement is necessary, it is only necessary to remove the unit 1 from the bottom plate 7 side of the backrest sb, and there is no need to disassemble the entire seat S. Moreover, even when the side support device is attached to a different model, it is only necessary to replace only the backrest b or process the attachment part, and the device is versatile even if the model is different.

In addition, the support member, key 14yj, and structure in the present invention are as follows:
The present invention is not limited to the above embodiments, and various known structures can be adopted. Further, the target seats can be those used for various purposes, such as for buggy vehicles, which are straddle-type vehicles such as three-wheeled or four-wheeled vehicles, for automobiles, and for other industrial vehicles.

[Effects of the Invention] Since the side support device of the present invention is unitized, it can be easily attached to and detached from the seat as a single unit. Therefore, it is versatile for a variety of different models. Therefore, it is particularly effective when attached to various types of sheets produced in small quantities of other products. Furthermore, since it is easy to install, repairs and replacements can be made without disassembling the entire seat.
