Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、自動二輪車用シートの防振装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a vibration isolating device for a motorcycle seat.
エンジンを支持するメインフレーム部にシートレールを
連結し、このシートレール上にシートを載置した自動二
輪車においては、シートレールとシート底板との間にゴ
ム製のダンパを介装している。In a motorcycle in which a seat rail is connected to a main frame portion that supports an engine and a seat is placed on the seat rail, a rubber damper is interposed between the seat rail and the seat bottom plate.
ところが、このシートはシート底板に設けた取付金具を
、シートレール側に引掛けたり、あるいはボルト締めす
ることでシートレールに固定されているので、このシー
ト底板をダンパにより弾性支持したり、金属に比べて振
動吸収性に富む合成樹脂製としても、上記取付金具を通
じてフレーム側の振動が直接シート底板に伝わってしま
う問題があっな。However, this seat is fixed to the seat rail by hooking the mounting bracket provided on the seat bottom plate to the seat rail side or tightening bolts, so the seat bottom plate is elastically supported by a damper or attached to metal. Even if the seat is made of synthetic resin, which has better vibration absorption properties, there is still the problem that vibrations from the frame side are transmitted directly to the seat bottom plate through the mounting bracket.
この振動対策として、従来、例えば「実開昭６０−４６
４８４号公報」に見られるように、シート底板の複数箇
所にウェイトを取付け、このウェイトによりシート底板
に伝わる振動を相殺することにより、シートの振動を軽
減するようにしたものが知られている。Conventionally, as a countermeasure against this vibration, for example,
As seen in Japanese Patent No. 484, it is known that weights are attached to multiple locations on the seat bottom plate, and the weights cancel out vibrations transmitted to the seat bottom plate, thereby reducing seat vibration.
ところが、この構成によると、シート底板に多くのウェ
イトを分散して取付けねばならないから、その分、構造
が複雑化するとともに、シートが重くなるといった不具
合がある。However, with this configuration, many weights must be distributed and attached to the seat bottom plate, which complicates the structure and increases the weight of the seat.
本発明はこのような事情にもとづいてなされたもので、
シート底板に複数のウェイトを設けることなく、このシ
ート底板に伝わる振動を軽減することができ、構造の簡
略化や軽量化を達成できる自動二輪車用シートの防振装
置の提供を目的とする。The present invention was made based on these circumstances, and
To provide a vibration isolating device for a motorcycle seat capable of reducing vibrations transmitted to the seat bottom plate without providing a plurality of weights on the seat bottom plate, and achieving simplified structure and weight reduction.
そこで、本発明においては、シート底板とフレームとを
連結する取付金具に、弾性部材を介して制振用質量体を
浮動状態に取付けたことを特徴とする。Therefore, the present invention is characterized in that a vibration damping mass body is attached in a floating state via an elastic member to a mounting bracket that connects the seat bottom plate and the frame.
この構成によれば、取付金具にフレーム側からエンジン
等の振動が伝わると、割振用質二体が取付金具とは独立
して振動することになり、この制振用質量体の固有振動
数を取付金具の振動数に応じて適宜設定すれば、単一の
制振用質量体によって取付金具の振動を盲動に［１殺す
ることかできる。According to this configuration, when vibrations from the engine, etc. are transmitted to the mounting bracket from the frame side, the two damping bodies vibrate independently of the mounting bracket, and the natural frequency of the damping mass body is reduced. If it is set appropriately according to the vibration frequency of the mounting bracket, the vibration of the mounting bracket can be suppressed by a single vibration damping mass.
このため、振動の主な入力部分でこの振動を吸収できる
から、シート底板に伝わる振動を効率良く軽減すること
ができ、従来のようにシート底板に数多くのウェイトを
分散して取付ける必要もなくなる。Therefore, since the vibrations can be absorbed at the main input part, the vibrations transmitted to the seat bottom plate can be efficiently reduced, and there is no need to distribute and attach a large number of weights to the seat bottom plate as in the past.
以下本発明を、図面に示す一実施例にもとづいて説明す

ム製の弾性体１２が取付けられている。A main seat 6 for the driver and a seat 1-7 for a fellow passenger, which is separate from the main seat 6, are arranged on the seat rail 5, one after the other. As shown in FIG. 1, the main seat 6 is made by laminating a cushioning material 9 on a synthetic resin seat bottom plate 8, and covering the cushioning material 9 with a seat skin 10. An elastic body 12 made of rubber is attached to the lower surface of the seat rail 5 and a seat receiver connecting the seat rails 5, which is in contact with a metal fitting 11.

左右一対の係止片部１７ａ。A mounting bracket 15 made of sheet metal is provided at the rear of the seat bottom plate 8 for fixing the main seat 6 onto the seat rail 5. The mounting bracket 15 includes a plate-shaped main portion 1G extending along the width direction of the seat bottom plate 8, and a pair of left and right locking pieces 17a extending downward from both ends of the plate-shaped main portion 16.

The tips of the locking pieces 17a and 17b pass through the through hole 20 in the upper surface 11a of the metal fitting 11. It is pivotally supported. The seat attachment/detachment lever 21 has both left and right ends 22 having locking pieces +7a,
It is removably engaged with the tip end of the locking piece 17b from both front and rear sides, and this engagement causes the locking piece 17a to close.

いる。By the way, the plate-shaped main portion 1G of the mounting bracket 15 is integrally formed with an extension portion 23 extending rearward.
A weight 24 serving as a vibration damping mass is elastically supported. To explain this support structure, the weight 24 is made of a ring-shaped rubber elastic member 25.
．． A bolt 27 is inserted into the center of the weight 24 and the elastic member 25 through a collar 26. This bolt 27 passes through the extension part 23, and when this penetration end is tightened with a nut 28, the elastic member 25.25 is compressed between the upper surface of the extension part 23 and the head 27a of the bolt 27, and the weight 24 is elastically supported in a floating state with respect to the extension part 23.
なお、このウェイト２４とカラー２６との間には、隙間
２９が形成されている。Note that a gap 29 is formed between the weight 24 and the collar 26.

ート底板８に伝わることになる。In such a configuration, the seat bottom plate 8 is made of a synthetic resin material that has better vibration absorption properties than metal, and the seat rail 5 and the seat support are in contact with the metal fittings 11 via the elastic body 12. Therefore, vibrations on the rear frame portion 4 side are attenuated to some extent and transmitted to the seat bottom plate 8, but this seat bottom! ! Since the mounting fitting 15 for fixing the i28 is directly engaged with the metal fitting 11 at the seat receiver on the rear frame portion 4 side, the vibration of the rear frame portion 4 is transmitted to the seat bottom plate 8 from here.
しかるに、上記構成においては、リヤフレーム部４から

２５．２５を介してウェイト２４を浮動状態に取付けた
ので、取付金具１５に振動が伝わると、ウェイト２４が
取付金具１５とは独立して振動する。However, in the above configuration, since the weight 24 is attached in a floating state to the mounting bracket 11, which is the input part of the main vibration from the rear frame portion 4, via the elastic members 25 and 25, the vibration is not transmitted to the mounting bracket 15. When the vibration is transmitted, the weight 24 vibrates independently of the mounting bracket 15.

振動を軽減することができる。For this reason, if the natural frequency of the weight 24 is appropriately set according to the frequency of the mounting bracket 15, this mounting ≦゛? Ingredients 15
The vibration transmitted to the seat bottom plate 8 can be reduced by simply providing a single weight 24.
したがって、従来のようにシート底板８に世故のウェイ
トを分散して取付ける必要もなくなるから、ウェイト２
４を始めとして、その取付は部も一つで済み、その分、
構造の簡略化や軽量化が可能となる。Therefore, there is no need to distribute and attach conventional weights to the seat bottom plate 8 as in the past.
Starting with 4, the installation only requires one part, so
It becomes possible to simplify the structure and reduce the weight.
なお、取付金具をリヤフレームに固定する手段は、上記
実施例に特定されるものではなく、例えば上記取付金具

ても良い。Note that the means for fixing the mounting bracket to the rear frame is not limited to the above-mentioned embodiment; for example, the mounting bracket may be fastened and fixed to a bracket on the rear frame side with bolts.

や軽量化が可能となる。According to the present invention described in detail below, the vibration of the mounting bracket can be reduced to (0).
This reduces the vibrations transmitted to the seat bottom plate, and eliminates the need to install multiple sea urchins and rudders separately on the seat bottom plate, as was the case in the past. Therefore, the installation of the weights and other parts requires only a few parts, which makes it possible to simplify the structure and reduce the weight.
