以下に、図面を参照しつつ本発明の好ましい実施の形態を示す。
図面は、本発明を自動車用リヤシートのシートバック前倒し機構に適用した場合を示すものであり、このロック解除操作用レバー装置は、例えば運転席側のドアトリム（図示せず）等に取り付けられている。
図１は、本発明のロック解除操作用レバー装置を示す斜視図であり、図中１は凹皿状のレバーベース、２，３はレバーベース１の開口部に設けられた第１および第２のレバー部材である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawing shows a case where the present invention is applied to a seat back forward tilt mechanism for a rear seat for an automobile, and this unlocking lever device is attached to, for example, a door trim (not shown) on the driver's seat side. .
FIG. 1 is a perspective view showing a lever device for unlocking operation of the present invention, in which 1 is a concave plate-like lever base, and 2 and 3 are first and second provided at the opening of the lever base 1. This is a lever member.

この第１のレバー部材２と第２のレバー部材３は、板状部材で形成されており、それぞれ単独のケーブルを介して別々のロック解除機構（図示せず）に連結されているとともに、同一軸となる軸４上で各々が独立して回動するよう上下に並列に配置されたものとなっている。
また、第１のレバー部材２と第２のレバー部材３の長さは長短２種類のものからなっており、長さの差分で形成される空間部が指の挿入部５を形成した構造となっている。 The first lever member 2 and the second lever member 3 are formed of plate-like members, and are connected to separate lock release mechanisms (not shown) via individual cables, and are the same. They are arranged in parallel in the vertical direction so that each of them independently rotates on the shaft 4 as a shaft.
Further, the lengths of the first lever member 2 and the second lever member 3 are two types of lengths, and the space formed by the difference in length forms the finger insertion portion 5. It has become.

更に、第２のレバー部材３の裏面には第２のレバー部材３から第１のレバー部材２に向かって突出する連動回動用のリブ６が設けられている。
即ち、リブ６の上端先端部６ａは第１のレバー部材２の裏面側に当接した状態となっており、第２のレバー部材３を回動すると前記リブ６に押されて第１のレバー部材２も同時に回動するよう構成されている。 Further, a rib 6 for interlocking rotation that protrudes from the second lever member 3 toward the first lever member 2 is provided on the back surface of the second lever member 3.
That is, the top end 6a of the upper end of the rib 6 is in contact with the back side of the first lever member 2, and when the second lever member 3 is rotated, the rib 6 is pushed to the first lever. The member 2 is also configured to rotate simultaneously.

このように構成したレバー装置では、第１のレバー部材２を回動すると、図２に示すように、軸４を中心にして独立に回動しケーブル（図示せず）を介して連結されているロック解除機構を作動し、ロックを解除することとなる。
一方、第２のレバー部材３を回動すると、図３に示すように、軸４を中心に回動するとともに、リブ６に押されて第１のレバー部材２も同時に回動することとなり、各々のケーブルを介して連結されている各々のロック解除機構を同時に作動し、各々のロックを解除することとなる。従って、一回のレバー操作によって、同時に２つのロック解除操作を行えることとなる。 In the lever device configured as described above, when the first lever member 2 is rotated, as shown in FIG. 2, it is independently rotated around the shaft 4 and connected via a cable (not shown). The lock release mechanism is activated and the lock is released.
On the other hand, when the second lever member 3 is rotated, as shown in FIG. 3, the second lever member 3 is rotated about the shaft 4, and the first lever member 2 is also simultaneously rotated by being pushed by the rib 6. Each unlocking mechanism connected via each cable is operated simultaneously to release each lock. Therefore, two unlocking operations can be performed simultaneously by a single lever operation.

なお図４に示すように、リブ６の突設位置を変えることにより、第２のレバー部材３の回動に伴い第１のレバー部材２が連動して回動するタイミングを調整するようにすることもできる。
即ち、第１および第２のレバー部材２，３をともに回動させていない状態で、リブ６の上端先端部６ａを第１のレバー部材２の裏面から離れた位置に設定することにより、第２のレバー部材３を所定角度分だけ回動させた場合にのみリブ６の上端先端部６ａが第１のレバー部材２の裏面側に当接した状態となり、第２のレバー部材３を更に回動させることにより第１のレバー部材２が連動して回動するようにタイミングを変化させるのである。これにより、第１のレバー部材２に連結されたロック解除機構のロック解除のタイミングを遅らせたり、第２のレバー部材３を少しだけ回動させることで第２のレバー部材３に連結されたロック解除機構のみのロックを解除操作したりすることが可能となる。 As shown in FIG. 4, the timing at which the first lever member 2 rotates in conjunction with the rotation of the second lever member 3 is adjusted by changing the protruding position of the rib 6. You can also.
That is, by setting the upper end tip portion 6a of the rib 6 at a position away from the back surface of the first lever member 2 in a state where both the first and second lever members 2 and 3 are not rotated, the first Only when the second lever member 3 is rotated by a predetermined angle, the top end 6a of the rib 6 comes into contact with the back side of the first lever member 2, and the second lever member 3 is further rotated. By moving, the timing is changed so that the first lever member 2 rotates in conjunction with the first lever member 2. As a result, the lock release mechanism connected to the first lever member 2 is delayed, or the second lever member 3 is slightly rotated so that the lock is connected to the second lever member 3. It becomes possible to release the lock of only the release mechanism.

次に、本発明のロック解除操作用レバー装置を車両用シートのアレンジ機構に組み込んだ場合について説明する。
図５は、第１のレバー部材２をケーブル１０を介してシートバック１１のリクライニングのロック解除機構１３に連結し、一方、第２のレバー部材３をケーブル１０を介してシートクッション１２のロック解除機構１４に連結した場合を示すものである。
この場合は、第１のレバー部材２を操作することによりシートバック１１を前倒しした状態とし、第２のレバー部材３を操作することによりシートクッション１２を前方側へ跳ね上げるとともに、シートバック１１を前倒しした状態として荷室の拡大を図るものであり、必要に応じていずれかを選択することができる。なお、第２のレバー部材３を操作した場合は、シートバック１１の回動に先立ちシートクッション１２の回動が行なわれる必要があるので、リブ６の突設位置を調整しておく必要がある。 Next, the case where the unlocking lever device of the present invention is incorporated in an arrangement mechanism for a vehicle seat will be described.
FIG. 5 shows that the first lever member 2 is connected to the reclining unlock mechanism 13 of the seat back 11 via the cable 10, while the second lever member 3 is unlocked of the seat cushion 12 via the cable 10. The case where it connects with the mechanism 14 is shown.
In this case, the seat back 11 is moved forward by operating the first lever member 2, the seat cushion 12 is flipped forward by operating the second lever member 3, and the seat back 11 is It is intended to enlarge the luggage compartment as being brought forward, and either can be selected as necessary. Note that when the second lever member 3 is operated, the seat cushion 12 needs to be rotated prior to the rotation of the seat back 11, so that the protruding position of the rib 6 needs to be adjusted. .

その他に、第１のレバー部材２をケーブルを介して前記シートバックのロック解除機構に連結し、一方、第２のレバー部材３をケーブルを介してトノカバーのロック解除機構（図示せず）に連結することもできる。
この場合は、シートバックを前倒しによる広い荷室確保を図るには、トノカバーがロックされていない状態では、第１のレバー部材２を単独操作することによりシートバック１１を前倒しした状態とし、またトノカバーがロックされている状態では、第２のレバー部材３を操作することによりトノカバーのロック解除に引き続きシートバックを前倒しする動作を連動させる操作を行えばよい。なお、第２のレバー部材３を操作した場合は、シートバック１１の回動に先立ちトノカバーのロック解除が行われるように、リブ６の突設位置を調整しておく。
また、このとき、第２のレバー部材３を少しだけ回動させることでトノカバーのロック解除のみを可能とするように調整することもできる。 In addition, the first lever member 2 is connected to the unlocking mechanism of the seat back via a cable, while the second lever member 3 is connected to the unlocking mechanism (not shown) of the tonneau cover via a cable. You can also
In this case, in order to secure a large luggage compartment by forcing the seat back forward, when the tonneau cover is not locked, the first lever member 2 is operated alone to bring the seat back 11 forward, and the tonneau cover In the locked state, the second lever member 3 may be operated so as to interlock the operation of moving the seat back forward after the unlocking of the tonneau cover. Note that when the second lever member 3 is operated, the protruding position of the rib 6 is adjusted so that the tonneau cover is unlocked prior to the rotation of the seat back 11.
Further, at this time, the second lever member 3 can be adjusted so that only the unlocking of the tonneau cover can be performed by slightly rotating the second lever member 3.

以上の説明からも明らかなように、本発明は凹皿状のレバーベースの開口部に、それぞれ別のロック解除機構に連結される第１および第２のレバー部材を同軸上で独立して回動するように並列に配置するとともに、該第１のレバー部材と第２のレバー部材の長さに差をもたせて指の挿入部を形成し、また第２のレバー部材の裏面には第２のレバー部材から第１のレバー部材に向かって突出する連動回動用のリブを設けたものとしたので、第１のレバー部材は単独で操作でき、一方、第２のレバー部材は第１のレバー部材と連動して両方が操作できることとなる。この結果、レバー装置の操作性の向上と小型化を図ることができ、また２つのレバー部材をまとめて配置するので外観品質も向上させることができることとなる。   As is clear from the above description, the present invention is configured such that the first and second lever members connected to the respective unlocking mechanisms are separately and coaxially rotated in the opening of the concave plate-like lever base. The first lever member and the second lever member are arranged in parallel to form a finger insertion portion with a difference in length between the first lever member and the second lever member. Since the rib for interlocking rotation protruding from the lever member toward the first lever member is provided, the first lever member can be operated independently, while the second lever member is the first lever. Both can be operated in conjunction with the member. As a result, the operability of the lever device can be improved and the size can be reduced, and since the two lever members are arranged together, the appearance quality can be improved.
