Description

本発明は、前倒しシートバックのロック解除用操作部構造に関する。     The present invention relates to an operation part structure for unlocking a forward-turning seat back.

従来の、例えばリャシートにはシートバックが水平状に前倒れし、その背面を荷台として利用できるものがある。
そして、このシートバックの前倒れ用の操作部材は例えば特開2002−209659号公報に開示されているように、シートバックの頂部に配設して、遠隔操作によってシートバックのロックを解除し、シートバックを前倒れするようにしている。
Some conventional rear seats, for example, have a seat back that folds down horizontally and can use the back as a loading platform.
And, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2002-209659, the operation member for tilting the seat back forward is disposed on the top of the seat back, and the seat back is unlocked by remote operation. The seat back is tilted forward.

従って、シートバックの前倒し操作は、シートバックの頂部まで手を延ばして行う必要があり、その操作性が悪い不具合がある。     Therefore, it is necessary to extend the seat back to the top of the seat back, and the operability is poor.

斯る不具合を除去するために、シートバックの頂部とそれ以外の例えば、シートバックの側部に各々操作レバーを設けたものが開示されている(例えば特開2005−52170号公報)。     In order to eliminate such a problem, there has been disclosed a system in which operation levers are provided at the top of the seat back and other parts such as the side of the seat back (for example, JP-A-2005-52170).

これは、シートバックの側面より操作レバーが外方に突出するため不具合があり、この不具合は例えば特開2000−108737号公報に開示されているように、操作レバーをシートバックの側面より突出しないような構造にしたものを応用することにより除去できる。     This is a problem because the operation lever protrudes outward from the side surface of the seat back, and this problem does not protrude from the side surface of the seat back as disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-108737. It can be removed by applying a structure having such a structure.

特開2002−209659号公報JP 2002-209659 A 特開2005−52170号公報JP 2005-52170 A 特開2000−108737号公報JP 2000-108737 A

以上のシートバックの下部側面側に、シートバックのロック解除用操作レバーを設けたものは、いずれも操作レバーを上方に回動操作してロックを解除する構造である。     Any of the above-described seat backs provided with an operation lever for unlocking the seat back has a structure in which the operation lever is pivoted upward to release the lock.

ところが、シートバックの前倒し操作時において、シートバックの前倒れ方向と、操作者の指先の操作レバーに対する操作力の方向とが向き合う方向になるため、操作レバーの操作性が頗る悪くなる。     However, when the seat back is moved forward, the operability of the operation lever becomes worse since the forward direction of the seat back and the direction of the operation force with respect to the operation lever of the operator's fingertip face each other.

そこで、本発明は横幅方向を操作レバーによって狭くすることのない前倒しシートバックにおいて、そのロック解除用操作レバーの操作性を向上させることを目的とする。     SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the operability of the unlocking operation lever in a forward-turning seat back in which the lateral width direction is not narrowed by the operation lever.

以上の目的を達成するための本発明に係る前倒しシートバックのロック解除用操作部構造は、リクライニングデバイスによって前倒れ可能に取付けたシートバックの側部前面に、前記リクライニングデバイスによるロック解除用の操作レバーを配設すると共に、該操作レバーは前方且つ下方への押し下げ可能に枢着し、該操作レバーの押し下げ操作によって前記リクライニングデバイスによるロックを解除することを特徴とする構成である。     In order to achieve the above object, the operation structure for unlocking the forward-facing seat back according to the present invention is the operation for unlocking by the reclining device on the front side of the seat back that is attached to the reclining device so as to be able to tilt forward. The lever is provided, and the operation lever is pivotally mounted so as to be able to be pushed forward and downward, and the lock by the reclining device is released by the depression operation of the operation lever.

そして、前記操作レバーは、リクライニングデバイスを被覆するカバー部材の収容部内に設け、該収容部における操作レバーの下部を挿通するスリットの上方には操作レバーの内面方向に膨出状に成形した異物侵入防止部を設けるようにするのが好ましい。     The operation lever is provided in a housing portion of a cover member that covers the reclining device, and a foreign object intruded into the inner surface of the operation lever is formed above the slit through the lower portion of the operation lever in the housing portion. It is preferable to provide a prevention part.

更に、前記操作レバーの上部内面には、内方にリブ状に突出する操作指位置決め部を設けるようにするのが望ましい。     Furthermore, it is desirable to provide an operation finger positioning portion that protrudes inwardly on the upper inner surface of the operation lever.

加えて、前記操作レバーの内面下部には、前記スリットを隠蔽する目隠し用突出部を設けると良い。     In addition, a blindfold protrusion for concealing the slit may be provided at a lower portion of the inner surface of the operation lever.

本請求項1の発明によれば、操作レバーを操作し、シートバックを前倒しする際に、シートバックの前倒れ方向と操作レバーの操作方向である押し下げ方向とが一致するため、操作者の指先による操作レバーの押し下げに追従してシートバックが前倒れする。従って、操作レバーの操作性が良好となり、前記従来品の不具合を除去できる。     According to the first aspect of the present invention, when the operation lever is operated and the seat back is moved forward, the forward tilt direction of the seat back coincides with the push-down direction that is the operation direction of the operation lever. The seat back tilts forward following the depression of the control lever. Accordingly, the operability of the operation lever is improved, and the problems of the conventional product can be eliminated.

本請求項2の発明によれば、カバー部材の収納部及びスリットに対する異物の侵入を異物侵入防止部により防止されるため、操作レバーの機能性、操作性の低下を防止できる。その結果、前記操作レバーの操作性の向上を確保できる。   According to the second aspect of the present invention, the entry of foreign matter into the housing portion and the slit of the cover member is prevented by the foreign matter entry prevention portion, so that the functionality and operability of the operation lever can be prevented from being lowered. As a result, the operability of the operation lever can be improved.

本請求項3の発明によれば、操作レバーに対する操作者の指先の位置が、操作指位置決め部によって、所定位置に位置決めされるため、操作レバーの操作性が安定し、操作レバーの操作性を一層向上させることができる。     According to the third aspect of the present invention, since the position of the operator's fingertip with respect to the operation lever is positioned at a predetermined position by the operation finger positioning portion, the operability of the operation lever is stabilized and the operability of the operation lever is reduced. This can be further improved.

本請求項4の発明によれば、操作レバーを押し下げた際、目隠し用突出部により、カバー部材の操作レバーの下部を挿通するスリットが隠蔽されると共に、スリット内への異物の侵入を防止できる。
そのため、操作レバーの押し下げ操作時における外観品質を損なうこともないし、操作レバーが異物によって操作性を損なうこともない。
According to the fourth aspect of the present invention, when the operating lever is pushed down, the blindfold projecting portion conceals the slit that passes through the lower portion of the operating lever of the cover member, and can prevent foreign matter from entering the slit. .
Therefore, the appearance quality at the time of the operation lever pressing operation is not impaired, and the operability of the operation lever is not impaired by the foreign matter.
