しかして、係合部材20は、前記ストライカ11の前側ロッド14がストライカ進入溝12に進入すると、最初は傾斜案内面22により案内されて上動し、ストライカ11の前側ロッド14が第一段係合溝24の下方に至ると係合し、次ぎに、操作伝達部材41により係合部材20を上動させると、ストライカ11は移動可能になって、奥側に進入させると、ストライカ11の後側ロッド15が第一段係合溝24の下方に至って係合し、前側ロッド14は第二段係合溝26に嵌合して退避する。
Below the striker entry groove 12 of the cover 40, a stopper surface 45 is formed to which the lower part of the lowest front inner peripheral surface 28 of the engagement member 20 abuts (FIG. 3).
Since the stopper surface 45 is formed by bending the cover 40 to be attached to the body 1, it is only necessary to attach the cover 40 to the body 1, and manufacturing and assembly are easy.
Thus, when the front rod 14 of the striker 11 enters the striker entry groove 12, the engaging member 20 is first guided by the inclined guide surface 22 to move upward, and the front rod 14 of the striker 11 is engaged in the first step. When the engagement member 20 is moved upward by the operation transmitting member 41 and then the striker 11 becomes movable, the striker 11 is moved to the back side. The side rod 15 reaches below the first stage engagement groove 24 and engages, and the front rod 14 is fitted into the second stage engagement groove 26 and retracts.
前記操作部材42を操作すると、操作伝達部材41が牽引されて、開放用部材36は図3の時計方向に回動し、開放用部材36の係合面37が係合体35に当接して係合部材20を上方回動させ、係合部材20からストライカ11が離脱可能となる。
開放用部材36には、係合面37に続いて非作用カム面48を形成する(図9〜図12等)。非作用カム面48は係合体35に当接するが、係合面37に比して係合体35の上方回動量を少なくする面形状に形成する。
即ち、前記非作用カム面48は、前記係合部材20の一段目の第一段係合溝24からストライカ11を離脱可能状態になると、前記係合体35が当接するよう構成する。
前記操作伝達部材41は、前記操作部材42を操作可能範囲で最大限に操作した場合であっても、寸法精度や取付誤差等の要因が重なることで、前記係合部材20がストライカ11から離脱した後も、前記開放用部材36を図3の時計方向に回動させ、前記係合体35に前記非作用カム面48が当接する構成とする。
When the operation member 42 is operated, the operation transmission member 41 is pulled, the release member 36 rotates in the clockwise direction of FIG. 3, and the engagement surface 37 of the release member 36 abuts on the engagement body 35 and engages. The striker 11 can be detached from the engagement member 20 by rotating the joint member 20 upward.
A non-working cam surface 48 is formed on the opening member 36 subsequent to the engaging surface 37 (FIGS. 9 to 12, etc.). The non-working cam surface 48 abuts on the engagement body 35, but is formed in a surface shape that reduces the amount of upward rotation of the engagement body 35 compared to the engagement surface 37.
That is, the non-working cam surface 48 is configured such that the engaging body 35 comes into contact when the striker 11 can be detached from the first-stage engaging groove 24 of the first stage of the engaging member 20.
Even when the operation transmission member 41 is operated to the maximum extent within which the operation member 42 can be operated, the engagement member 20 is detached from the striker 11 due to overlapping factors such as dimensional accuracy and mounting errors. After that, the opening member 36 is rotated in the clockwise direction in FIG. 3 so that the non-operating cam surface 48 contacts the engaging body 35.
また、前記非作用カム面48は、前記係合体35が当接すると、当接状態を保持しつつ該係合体35のアンラッチ方向への回動量を少なくする面形状に形成する。
換言すると、非作用カム面48は、係合部材取付軸21の軸芯から外れた任意の点Pを中心とした円弧形状で、開放用部材36を上方回動させるに従い係合体35の上方回動量を少なくする形状に形成する。
この場合、非作用カム面48は、係合体35の上方回動量を少なくさせるが、必ず、互いに当接するようにし、非作用カム面48の下方回動により係合体35を元に戻す。
また、非作用カム面48に続く開放用部材36の外周は退避面49に形成する(図9)。退避面49は開放用部材36が係合部材20を上方回動させた状態でも、ストライカ進入溝12の上縁より所定間隔上方に位置するように配置する(図6)。
The non-working cam surface 48 is formed in a surface shape that reduces the amount of rotation of the engagement body 35 in the unlatching direction while maintaining the contact state when the engagement body 35 abuts.
In other words, the non-working cam surface 48 has an arc shape centered at an arbitrary point P deviated from the axis of the engagement member mounting shaft 21 and rotates upwardly of the engagement body 35 as the release member 36 is rotated upward. It is formed in a shape that reduces the amount of movement.
In this case, the non-operating cam surface 48 reduces the amount of upward rotation of the engaging body 35, but is always brought into contact with each other, and the engaging body 35 is returned to its original position by rotating the non-operating cam surface 48 downward.
Further, the outer periphery of the opening member 36 following the non-working cam surface 48 is formed on the retracting surface 49 (FIG. 9). The retracting surface 49 is arranged so as to be positioned above the upper edge of the striker entry groove 12 by a predetermined distance even when the opening member 36 rotates the engaging member 20 upward (FIG. 6).

実施例では、カバー40にアウタ係止部103を設けている。
該アウタ係止部103には前記一方側挿通孔110および他方側挿通孔111に対向させてアウターチューブ100の端部の取付部材120を係止する係合溝121を設ける。
前記ケーブル係止部105のベース板部115と対向板部117とは左右に所定間隔おいて設ける。
即ち、係合板部116の下面に当接してる先端係合部104に対してケーブル係止部105が上方回動可能に構成する。
That is, the outer locking portion 103 is the body 1 or the upper position in the crossing direction with respect to the moving direction of the cable locking portion 105 of the operation transmitting means 36 when the operating member 20 moves from the latched state to the unlatched state. Provided on the cover 40.
In the embodiment, the outer locking portion 103 is provided on the cover 40.
The outer locking portion 103 is provided with an engagement groove 121 that locks the attachment member 120 at the end of the outer tube 100 so as to face the one side insertion hole 110 and the other side insertion hole 111.
The base plate portion 115 and the counter plate portion 117 of the cable locking portion 105 are provided at a predetermined interval on the left and right.
That is, the cable locking portion 105 is configured to be rotatable upward with respect to the distal end engaging portion 104 that is in contact with the lower surface of the engaging plate portion 116.
また、前記作動伝達手段36の本体123は、前記係合板部116より反ケーブル係止部105側に移動する先端係合部104と干渉しない厚さに形成する。
即ち、前記作動伝達手段36の本体123がアンラッチ操作により上方回動するとき、操作されずに留まっている先端係合部104の非係合状態を保持して本体123が上方回動するように、前記係合板部116より反ケーブル係止部105側に移動する先端係合部104と干渉しない厚さに形成する。
前記係合板部116に対向する作動伝達手段36の本体123には、係合板部116側が低く、係合板部116に離れるに従い高くなる傾斜面124を形成する。傾斜面124は、操作されずに留まっている先端係合部104をそのままにして、作動伝達手段36の本体123の回動を円滑に行う。
Further, the main body 123 of the operation transmission means 36 is formed to a thickness that does not interfere with the distal end engaging portion 104 that moves to the side opposite to the cable locking portion 105 from the engaging plate portion 116.
That is, when the main body 123 of the operation transmission means 36 is rotated upward by an unlatching operation, the main body 123 is rotated upward while maintaining the disengaged state of the tip engaging portion 104 that remains without being operated. The thickness is set so as not to interfere with the front end engaging portion 104 moving to the side opposite to the cable locking portion 105 from the engaging plate portion 116.
The main body 123 of the operation transmission means 36 facing the engagement plate portion 116 is formed with an inclined surface 124 that is low on the engagement plate portion 116 side and increases as the distance from the engagement plate portion 116 increases. The inclined surface 124 smoothly rotates the main body 123 of the operation transmission means 36 while leaving the tip engaging portion 104 remaining without being operated.
しかして、前記操作伝達部材41の装置の操作機構は、種々の機器に使用(応用)できるが、本願では、前記装置Lを、車両用シート1の背凭シート6と車体3のと間に設けた前記背凭シート6を所定位置に保持するラッチ装置Lとしている。
また、作動伝達手段36が作動させる前記作動部材20は車体3に固定したストライカ11に係合する係合部材20としている。
そして、ケーブル係止部105は、金属板部材を屈曲形成し、これに一方側挿通孔110〜嵌合孔113を形成し、このケーブル係止部105を樹脂部材により構成される作動伝達手段36の本体123に一体形成している。
そのため、作動伝達手段36のケーブル係止部105に、前記背凭シート6から離れた所定位置に設けた一方側操作部材42Aに接続した一方側ケーブル41Aと、前記背凭シート6に設けた他方側操作部材42Bに接続した他方側ケーブル41Bとの夫々のインナーケーブル101の先端係合部104を夫々係止し、二カ所からの背凭シート6のリクライニングあるいは倒伏操作を行える。
Thus, the operation mechanism of the device of the operation transmission member 41 can be used (applied) to various devices. In the present application, the device L is disposed between the back seat 6 of the vehicle seat 1 and the vehicle body 3. A latch device L is provided for holding the provided back sheet 6 in a predetermined position.
The actuating member 20 actuated by the actuating transmission means 36 is an engaging member 20 that engages with the striker 11 fixed to the vehicle body 3.
The cable locking portion 105 is formed by bending a metal plate member, and one side insertion hole 110 to fitting hole 113 is formed in the metal plate member, and the cable transmitting portion 105 is formed of a resin member. The body 123 is integrally formed.
Therefore, one end of the cable 41A connected to the one side operation member 42A provided at a predetermined position away from the backrest seat 6 and the other end provided on the backrest seat 6 are connected to the cable locking portion 105 of the operation transmitting means 36. The front end engaging portion 104 of each inner cable 101 with the other side cable 41B connected to the side operation member 42B is locked, and the reclining or lying down operation of the dorsal seat 6 can be performed from two places.
(実施例の作用)
背凭シート6は通常着座位置から車体3に対して上側部分を取付軸7中心に前方回動させると、背凭シート6の後面が略平らとして、車室空間を広くする。
また、通常着座位置からラッチ装置Lをアンラッチにさせて、通常着座位置から傾斜させたリクライニング位置とやや後傾させることができる。
例えば、アンラッチ状態でラッチ装置Lにストライカ11が係合していない前倒し状態の背凭シート6を起こすと、ボディ1のストライカ進入溝12にストライカ11が進入し、ストライカ11は係合部材20の傾斜案内面22に当接し、傾斜案内面22は係合部材20をバネ55に抗して係合部材取付軸21中心に上方回動させるように案内し、ストライカ11の前側ロッド14が傾斜案内面22を通過して第一段係合溝24の下方に至ると、係合部材20はバネ55の弾力によりストライカ11の前側ロッド14に係合する。
(Operation of Example)
When seatback 6 is rotated forward to axis 7 around Mounting the upper portion relative to the vehicle body 3 from the normal seating position, the rear surface of the backrest seat 6 is a substantially flat, to increase the vehicle compartment space.
Further, the latch device L can be unlatched from the normal seating position, and can be tilted slightly rearward from the reclining position tilted from the normal seating position.
For example, when the dorsal seat 6 in the forward-turned state in which the striker 11 is not engaged with the latch device L in the unlatched state is raised, the striker 11 enters the striker entry groove 12 of the body 1, and the striker 11 The inclined guide surface 22 contacts the inclined guide surface 22 and guides the engaging member 20 to rotate upward about the engaging member mounting shaft 21 against the spring 55, and the front rod 14 of the striker 11 is inclined and guided. When passing through the surface 22 and below the first stage engagement groove 24, the engagement member 20 is engaged with the front rod 14 of the striker 11 by the elasticity of the spring 55.
したがって、背凭シート6を起立させたときは、何の操作をすることなく、起立させただけで、係合部材20はストライカ11に係合し、背凭シート6を通常位置に保持でき、操作性を向上させる。
係合部材20の第一段係合溝24の係合部材取付軸21側には別の第二段係合溝26が形成され、係合部材20の係合体35には、他端は任意のノブ等の操作部材42に係止した開放用部材36の係合面37を臨ませているから、開放用部材36を操作伝達部材41により上動させると、開放用部材36の係合面37は係合体35を係合部材取付軸21中心に上方回動させ、これにより係合部材20は係合部材取付軸21中心に上方回動して、第一段係合溝24よりストライカ11の前側ロッド14を離脱が可能となる。
Therefore, when the dorsal seat 6 is erected, the engagement member 20 can be engaged with the striker 11 without holding any operation, and the dorsal seat 6 can be held in the normal position. Improve operability.
Another second stage engagement groove 26 is formed on the engagement member mounting shaft 21 side of the first stage engagement groove 24 of the engagement member 20, and the other end of the engagement body 35 of the engagement member 20 is arbitrary. Since the engagement surface 37 of the release member 36 that is locked to the operation member 42 such as a knob is exposed, when the release member 36 is moved upward by the operation transmission member 41, the engagement surface of the release member 36 37 rotates the engaging body 35 upward about the engaging member mounting shaft 21, whereby the engaging member 20 rotates upward about the engaging member mounting shaft 21, and the striker 11 is moved from the first stage engaging groove 24. The front rod 14 can be detached.
開放用部材36の係合面37は係合体35との間に所定の隙間38を設けているから、開放用部材36の係合面37が所定量回動した後係合体35に当接して回動させる。
したがって、係合面37から操作部材42までの間の製造誤差等により発生する長さの相違があっても、隙間38がこれを吸収し、操作部材42は常時一定位置に位置させることができ、かつ、確実に操作を伝達する。
次ぎに、この状態で、背凭シート6を後側に倒すと、ストライカ11の前側ロッド14および後側ロッド15はストライカ進入溝12の奥側に向けて進入し、後側ロッド15が係合部材20の第二段係合溝26の奥の奥側内周面31に当接し、次ぎに、操作部材42を離すと、係合部材20はバネ55の弾力により、第一段係合溝24にストライカ11の後側ロッド15が係合し、第二段係合溝26にストライカ11の前側ロッド14が緩く嵌合し、背凭シート6はリクライニング位置に保持される。
Since the engagement surface 37 of the release member 36 is provided with a predetermined gap 38 between the engagement body 35 and the engagement surface 37 of the release member 36 is rotated by a predetermined amount, the engagement surface 37 contacts the engagement body 35. Rotate.
Therefore, even if there is a difference in length caused by a manufacturing error between the engagement surface 37 and the operation member 42, the gap 38 absorbs this, and the operation member 42 can always be positioned at a certain position. And the operation is transmitted reliably.
Next, in this state, when the dorsal seat 6 is tilted rearward, the front rod 14 and the rear rod 15 of the striker 11 enter toward the back side of the striker entry groove 12, and the rear rod 15 is engaged. When the operation member 42 is released after coming into contact with the inner peripheral surface 31 at the back of the second-stage engagement groove 26 of the member 20, the engagement member 20 is moved by the elasticity of the spring 55 to the first-stage engagement groove. side rod 15 after the striker 11 engages the 24, the front rod 14 is loosely fitted in the striker 11 to the second stage engaging grooves 26, backrest seat 6 is held in Rikurainin grayed position.
この場合、第一段係合溝24の前側内周面28は、係合状態のとき、下方に至るに従い後側になるように直線または円弧状に傾斜させ、後側内周面27と前側内周面28の前後幅は上方に至る従い狭く形成しているので、後側ロッド15がストライカ11が第一段係合溝24の上部に隙間を残して後側内周面27と前側内周面28の両者に当接して係合する。
したがって、ストライカ11が係合部材20に対して前後する「がた」および異音の発生を防止する。
また、背凭シート6がリクライニング状態では、ストライカ11の前側ロッド14は第二段係合溝26の後側内周面29および奥側内周面31の何れにも当接しないので、「がた」および異音の発生を防止する。
In this case, the front inner peripheral surface 28 of the first stage engaging groove 24 is inclined in a straight line or an arc shape so as to become the rear side as it goes downward in the engaged state, so that the rear inner peripheral surface 27 and the front side are inclined. Since the front-rear width of the inner peripheral surface 28 is formed narrower upward, the rear rod 15 causes the striker 11 to leave a gap above the first stage engaging groove 24 and the rear inner peripheral surface 27 and the front inner surface. Abuts and engages both of the peripheral surfaces 28.
Therefore, the “gap” that the striker 11 moves back and forth with respect to the engaging member 20 and the generation of abnormal noise are prevented.
Further, when the dorsal seat 6 is in the reclining state, the front rod 14 of the striker 11 does not come into contact with either the rear inner peripheral surface 29 or the rear inner peripheral surface 31 of the second-stage engagement groove 26. "And" prevent the generation of abnormal noise.
係合部材20の第一段係合溝24は、ストライカ11側に位置する後側内周面27と係合部材取付軸21側に位置する前側内周面28とを有するが、前側内周面28の下端を前記後側内周面27の下端より下方に位置するように形成しているから、ストライカ11が傾斜案内面22に当接し、係合部材20を上方回動させつつストライカ11が進入して後側内周面27の下端を通過したとき、ストライカ11は前側内周面28に必ず当たる。
したがって、背凭シート6を起立させると、係合操作が不要なだけでなく、必ず、一段目の第一段係合溝24に係合する。
The first stage engaging groove 24 of the engaging member 20 has a rear inner peripheral surface 27 located on the striker 11 side and a front inner peripheral surface 28 located on the engaging member mounting shaft 21 side. Since the lower end of the surface 28 is formed so as to be positioned below the lower end of the rear inner peripheral surface 27, the striker 11 contacts the inclined guide surface 22, and the striker 11 is rotated while the engaging member 20 is rotated upward. When strikes and passes through the lower end of the rear inner peripheral surface 27, the striker 11 always hits the front inner peripheral surface 28.
Accordingly, when the dorsal seat 6 is erected, not only the engagement operation is unnecessary, but also the first-stage engagement groove 24 is always engaged.
前側内周面28は下方に至るに従い後側になるように直線または円弧状に傾斜しているから、ストライカ11との係合状態から非係合状態に係合部材20を上方回動させたとき、前側内周面28はストライカ11から離れる。したがって、ストライカ11と係合部材20の相対位置を変化させずに、離脱させるので、非係合操作のとき、操作荷重を重くしない。
即ち、前側内周面28が実施例と反対に、前側に傾斜させると、前側内周面28はストライカ11を押しながら離脱することになるので、着座者の背中を押しながら移動することになって、その分操作荷重が重くなるが、これを解消する。
Since the front inner circumferential surface 28 is inclined linearly or arcuately so as to become the rear side as it goes downward, the engagement member 20 is rotated upward from the engagement state with the striker 11 to the non-engagement state. At this time, the front inner circumferential surface 28 is separated from the striker 11. Accordingly, the striker 11 and the engaging member 20 are separated without changing the relative positions, so that the operation load is not increased during the non-engaging operation.
That is, when the front inner peripheral surface 28 is inclined to the front side as opposed to the embodiment, the front inner peripheral surface 28 is released while pushing the striker 11, so that it moves while pushing the back of the seated person. Therefore, the operation load becomes heavier, but this is eliminated.
前側内周面28の下部は第二段係合溝26の後側内周面29の下部より低く、前側内周面28の下部と第二段係合溝26の後側内周面29の間は後側に至るに従い高くなるように傾斜させているから、不慮の原因により係合状態で係合部材20が上下に振動しても、第一段係合溝24から外れて第二段係合溝26に係合することはない。
また、前側内周面28の下部と前記第二段係合溝26の後側内周面29の間は後側に至るに従い高くなるように傾斜させているから、第二段係合溝26から離脱させるとき、ストライカ11は最も低い前側内周面28の下部を通過することになって第一段係合溝24に係合することも無く、ワンモーションでストライカ11をフリー状態にする。
The lower part of the front inner peripheral surface 28 is lower than the lower part of the rear inner peripheral surface 29 of the second stage engaging groove 26, and the lower part of the front inner peripheral surface 28 and the rear inner peripheral surface 29 of the second stage engaging groove 26 are arranged. Since the gap is inclined so as to increase toward the rear side, even if the engagement member 20 vibrates up and down in an engaged state due to an unforeseen cause, the second stage is separated from the first stage engagement groove 24. The engaging groove 26 is not engaged.
Further, since the space between the lower portion of the front inner peripheral surface 28 and the rear inner peripheral surface 29 of the second stage engaging groove 26 is inclined to reach the rear side, the second stage engaging groove 26 is provided. When the striker 11 is disengaged, the striker 11 passes through the lower part of the lowest front inner peripheral surface 28 and does not engage with the first-stage engagement groove 24, so that the striker 11 is brought into a free state in one motion.
また、前側内周面28の下部は前記第二段係合溝26の後側内周面29の下部より低く、前側内周面28の下部と前記第二段係合溝26の後側内周面29の間は後側に至るに従い高くなるように傾斜させているから、係合部材20の最も低い前側内周面28の下部をストッパー面45の上面に当接させると、ストライカ11が傾斜案内面22に当接して係合部材20を上方回動させるように、係合部材20を待機位置に待機させる。
したがって、倒伏上体から起こすとき、傾斜案内面22によって係合させるための操作が不要なだけでなく、起立状態から倒伏させたときも、係合部材20はストッパー面45とバネ55の作用により初期自動復帰し、係合待機操作をも不要にする。
Further, the lower part of the front inner peripheral surface 28 is lower than the lower part of the rear inner peripheral surface 29 of the second stage engaging groove 26, and the lower part of the front inner peripheral surface 28 and the rear inner part of the second stage engaging groove 26. since between the peripheral surface 29 is inclined so as to be higher in accordance reach the rear and is brought into contact with the bottom of the lowest front inner peripheral surface 28 of the engagement member 20 on the upper surface of the stopper surface 45, the scan Toraika 11 Makes the engaging member 20 stand by at the standby position so that the engaging member 20 contacts the inclined guide surface 22 and rotates the engaging member 20 upward.
Therefore, not only is the operation for engaging with the inclined guide surface 22 unnecessary when raising from the lying upper body, but the engaging member 20 is also caused by the action of the stopper surface 45 and the spring 55 when lying down from the standing state. The initial automatic return is performed, and the engagement standby operation is also unnecessary.
しかして、ストライカ11の前側ロッド14と後側ロッド15の間隔は、係合部材20の第一段係合溝24と第二段係合溝26との間の間隔よりも広く、前記後側ロッド15が第一段係合溝24に係合すると、前記前側ロッド14は第二段係合溝26の内周との間に隙間を有する構成としているので、係合部材20とストライカ11との係合を、第一段係合溝24に前側ロッド14または後側ロッド15を係合させることで達成でき、第二段係合溝26に対して前側ロッド14は遊びを有して嵌るだけなので、「がた」および異音の発生を防止する確実性を向上させることができる。   Thus, the interval between the front rod 14 and the rear rod 15 of the striker 11 is wider than the interval between the first-stage engagement groove 24 and the second-stage engagement groove 26 of the engagement member 20. When the rod 15 engages with the first stage engaging groove 24, the front rod 14 has a gap between the inner periphery of the second stage engaging groove 26, so that the engaging member 20, the striker 11, Can be achieved by engaging the front rod 14 or the rear rod 15 with the first stage engagement groove 24, and the front rod 14 fits with respect to the second stage engagement groove 26. Therefore, it is possible to improve the certainty for preventing the occurrence of “ra” and abnormal noise.
換言すると、ストライカ11の前側ロッド14と後側ロッド15の間隔Tは、第一段係合溝24の前側内周面28と第二段係合溝26の後側内周面29との間の間隔T’よりも広く、かつ、傾斜案内面22の前側内周面28と第二段係合溝26の奥側内周面31との間隔tよりも狭く構成しているので、第一段係合溝24に前側ロッド14または後側ロッド15を必ず係合させる構成を簡単に実現できる。
ストライカ11の前側ロッド14と後側ロッド15との間の間隔を、第一段係合溝24と第二段係合溝26との間隔より広くし、前側ロッド14のみを係合させる構成とすると、ストライカ11が大型化し、ストライカ11の強度を確保するために重くなる。
In other words, the distance T between the front rod 14 and the rear rod 15 of the striker 11 is between the front inner peripheral surface 28 of the first step engagement groove 24 and the rear inner peripheral surface 29 of the second step engagement groove 26. 1 and is narrower than the distance t between the front inner peripheral surface 28 of the inclined guide surface 22 and the rear inner peripheral surface 31 of the second stage engaging groove 26. A configuration in which the front rod 14 or the rear rod 15 is always engaged with the step engagement groove 24 can be easily realized.
A configuration in which the interval between the front rod 14 and the rear rod 15 of the striker 11 is made wider than the interval between the first-stage engagement groove 24 and the second-stage engagement groove 26 and only the front rod 14 is engaged. Then, the striker 11 becomes larger and becomes heavier to ensure the strength of the striker 11.
また、前側ロッド14と後側ロッド15の夫々を、第一段係合溝24と第二段係合溝26の夫々に係合させる構成とすると、高い寸法精度と取付精度が要求され、製造が面倒である。
本発明は、前側ロッド14と後側ロッド15との間の間隔を小さくしながら、第一段係合溝24に、前側ロッド14と後側ロッド15の夫々を係合させて、ガタのない係合状態とし、更に、第二段係合溝26に対して前側ロッド14は遊びを有して嵌ることにより、寸法誤差と取付誤差を吸収する。
前記係合部材20の係合体35に当接する開放用部材36には、係合面37に続いて非作用カム面48を形成し、非作用カム面48は係合体35に当接するが、係合体35(係合部材20)の上方回動量を少なくする面形状に形成しているので、操作部材42所定位置から操作は、開放用部材36係合体35に対する空振のように係合体35の上方回動量を少なくし、操作伝達部材41と操作部材42等の操作系の破損を防止する。
Further, when the front rod 14 and the rear rod 15 are respectively engaged with the first-stage engagement groove 24 and the second-stage engagement groove 26, high dimensional accuracy and mounting accuracy are required, and manufacturing is performed. Is troublesome.
In the present invention, the gap between the front rod 14 and the rear rod 15 is reduced, and the front rod 14 and the rear rod 15 are engaged with the first-stage engagement groove 24 so that there is no backlash. In addition, the front rod 14 is fitted with play in the second stage engaging groove 26 to absorb dimensional errors and mounting errors.
The release member 36 that contacts the engagement body 35 of the engagement member 20 is formed with a non-action cam surface 48 following the engagement surface 37, and the non-action cam surface 48 contacts the engagement body 35. since the formed surface shape to reduce the upward rotation amount of polymer 35 (engaging member 20), from a predetermined position of the operation member 42 operated, the infrasound of open- member 36 against the engaging member 35 Thus, the amount of upward rotation of the engagement body 35 is reduced, and the operation system such as the operation transmission member 41 and the operation member 42 is prevented from being damaged.
即ち、開放用部材36の係合面37は隙間38の分だけ所定量回動した後係合体35に当接し、当接すると、係合面37は係合体35を係合部材取付軸21中心にイ方向へ移動させ(図9)、係合部材20の前側内周面28がストライカ11(前側ロッド14または後側ロッド15)を通過すると、係合体35は係合面37から非作用カム面48に移動する(図10〜図11)。
非作用カム面48は、係合体35(係合部材20)の上方回動量を少なくする面形状に形成しているので、操作部材42により開放用部材36を更に上方回動させても、係合体35の上方移動方向を当初の図12のロ方向からイ方向と変化させて、係合体35の上方回動量を係合面37に比し少なくする。
In other words, the engagement surface 37 of the opening member 36 is rotated by a predetermined amount by the gap 38 and then comes into contact with the engagement body 35. When the contact is made, the engagement surface 37 causes the engagement body 35 to center on the engagement member mounting shaft 21. When the front inner peripheral surface 28 of the engagement member 20 passes the striker 11 (the front rod 14 or the rear rod 15), the engagement body 35 is moved from the engagement surface 37 to the non-acting cam. It moves to the surface 48 (FIGS. 10 to 11).
Since the non-acting cam surface 48 is formed in a surface shape that reduces the upward rotation amount of the engagement body 35 (engagement member 20), even if the opening member 36 is further rotated upward by the operation member 42, the engagement cam surface 48 is engaged. The upward movement direction of the combined body 35 is changed from the initial direction of FIG.
したがって、開放用部材36は、非作用カム面48により係合体35(係合部材20)の上方回動量を少なくし、操作部材42による過剰な操作力を係合体35に対して非作用カム面48を移動させて逃がし、操作部材42と操作伝達部材41等の破損変形を防止する。
また、非作用カム面48は、係合体35の上方回動量を少なくする面形状なため、係合部材20の下方回動に対しては受け止めるように作用するので、係合部材20がバネ55の弾力によりラッチ位置へ移動するときは、係合体35は非作用カム面48から係合面37に続いて当接して元の位置に復帰する。
また、非作用カム面48に続く開放用部材36の外周は退避面49に形成し、非作用カム面48および退避面49は開放用部材36が係合部材20を上方回動させた状態でも、ストライカ進入溝12の上縁より所定間隔上方に位置するように配置しているので、ストライカ進入溝12の上下幅を広くし、ストライカ11の進入を容易・円滑にする。
Therefore, the opening member 36 reduces the amount of upward rotation of the engagement body 35 (engagement member 20) by the non-operation cam surface 48, and an excessive operation force by the operation member 42 is applied to the engagement body 35 by the non-operation cam surface. 48 is moved to escape and the breakage and deformation of the operation member 42 and the operation transmission member 41 are prevented.
Further, since the non-operating cam surface 48 has a surface shape that reduces the amount of upward rotation of the engaging body 35, the non-operating cam surface 48 acts to receive the downward rotation of the engaging member 20. When it moves to the latch position by the elasticity of, the engagement body 35 comes into contact with the engagement surface 37 from the non-acting cam surface 48 and returns to the original position.
Further, the outer periphery of the opening member 36 following the non-working cam surface 48 is formed on the retreating surface 49, and the non-working cam surface 48 and the retreating surface 49 are formed even when the opening member 36 rotates the engaging member 20 upward. Since the striker entry groove 12 is arranged so as to be positioned above the upper edge of the striker entry groove 12, the vertical width of the striker entry groove 12 is widened so that the striker 11 can enter easily and smoothly.
係合部材20をラッチ位置に付勢するバネ55は、コイル部56を係合部材取付軸21に挿通し、先に、バネ55の一端57を係合部材20の取付溝58に係止する。
この状態で、係合部材20をカバー40に取付ける。
次に、バネ55の他端59を、カバー40に設けた係合突起60に係合させる。
係合突起60は前記係合部材取付軸21の軸芯より上方に設け、係合突起60の下方のカバー40には切欠部62を形成しているから、係合部材取付軸21の後側および係合突起60の周辺に他端59を係止させるスペースを充分に広く確保でき、作業を頗る容易にする。
また、バネ55の他端59を係合突起60へ係合させるので、他端59を大きく弾性変形させることができ、しかも切欠部62により弾性変形させるスペースも充分にあって、他端59の係止作業を容易にする。
The spring 55 that urges the engaging member 20 to the latch position passes the coil portion 56 through the engaging member mounting shaft 21 and first locks one end 57 of the spring 55 in the mounting groove 58 of the engaging member 20. .
In this state, the engaging member 20 is attached to the cover 40.
Next, the other end 59 of the spring 55 is engaged with an engagement protrusion 60 provided on the cover 40.
Since the engaging protrusion 60 is provided above the axis of the engaging member mounting shaft 21 and the cover 40 below the engaging protrusion 60 is formed with a notch 62, the rear side of the engaging member mounting shaft 21 is provided. In addition, it is possible to secure a sufficiently large space for engaging the other end 59 around the engagement protrusion 60, thereby facilitating work.
Further, since the other end 59 of the spring 55 is engaged with the engaging protrusion 60, the other end 59 can be greatly elastically deformed, and there is also a sufficient space for elastic deformation by the notch 62. Makes locking work easier.
例えば、バネ55の他端59を、切欠部62から係合部材取付軸21の軸芯方向に移動させて、係合突起60へ係合させることができ、係止作業を容易にする。
切欠部62に対向する部分のボディ10には、後側フランジ部63を設けているので、ボディ10とカバー40とを合わせたとき、後側フランジ部63は切欠部62内に位置して、カバー40のベース縦板部61に当接または近接し、バネ55の一端57の外れ防止の作用を奏する。
しかして、ラッチ装置Lは、ボディ1とカバー40との間に係合部材20を挟持して構成し、ボディ1とカバー40と係合部材20とは、夫々係合部材取付軸21により組立てるから、組立てが非常に容易である。

For example, the other end 59 of the spring 55 can be moved from the notch 62 in the axial direction of the engaging member mounting shaft 21 and can be engaged with the engaging protrusion 60, facilitating the locking operation.
Since the rear flange 63 is provided in the body 10 at the portion facing the notch 62, when the body 10 and the cover 40 are combined, the rear flange 63 is located in the notch 62, It abuts on or is close to the base vertical plate portion 61 of the cover 40, and acts to prevent the one end 57 of the spring 55 from coming off.
Therefore, the latch device L is configured by sandwiching the engaging member 20 between the body 1 and the cover 40, and the body 1, the cover 40, and the engaging member 20 are assembled by the engaging member mounting shaft 21. Therefore, assembly is very easy.
Since the peripheral position of the striker entry groove 12 of each of the body 10 and the cover 40 is provided with a peripheral rib 65 improves the rigidity of the body 10 and the cover 40.
即ち、ラッチ装置Lは、ラッチ装置Lの上下中間位置にストライカ進入溝12があるため、ストライカ進入溝12によりラッチ装置Lは上下に分断され、ストライカ進入溝12はラッチ装置Lの剛性を低下させる原因の一つとなるが、本願では、ボディ10およびカバー40の各ストライカ進入溝12の周縁に周辺リブ65を設けているので、ラッチ装置Lの剛性が低くなる点を補強し、ラッチ装置L全体の剛性を向上させることができる。
ボディ10のストライカ進入溝12の入口部分には、周辺リブ65より深く押圧形成した段部66を設けているので、組み立てたボディ10とカバー40の剛性を向上させる。
That is, since the latch device L has the striker entry groove 12 at the upper and lower intermediate positions of the latch device L, the latch device L is divided vertically by the striker entry groove 12, and the striker entry groove 12 reduces the rigidity of the latch device L. One of the causes is that in the present application, since the peripheral rib 65 is provided at the periphery of each striker entry groove 12 of the body 10 and the cover 40, the point that the rigidity of the latch device L is lowered is reinforced, and the entire latch device L The rigidity of can be improved.

前記バネ55の他端59を係合させる係合突起60は、ベース縦板部61よりボディ10側に屈曲形成させているので、係合突起60付近のカバー40の剛性を向上させる。
また、バネ55の一端57の外れ防止作用を奏する後側フランジ部63は、ストライカ進入溝12側に屈曲形成させているので、後側フランジ部63付近のボディ10の剛性を向上させる。
即ち、係合突起60はカバー40のベース縦板部61よりボディ10側に屈曲形成させ、ボディ10の後側フランジ部63はベース縦板部64よりカバー40側に屈曲形成させているので、係合部材取付軸21周辺のラッチ装置Lの剛性を向上させられる。
Since the engagement protrusion 60 that engages the other end 59 of the spring 55 is bent toward the body 10 from the base vertical plate portion 61, the rigidity of the cover 40 in the vicinity of the engagement protrusion 60 is improved.
Further, since the rear flange portion 63 that prevents the one end 57 of the spring 55 from being detached is bent toward the striker entry groove 12, the rigidity of the body 10 in the vicinity of the rear flange portion 63 is improved.
That is, the engaging projection 60 is bent formed on the body 10 side of the base over the scan vertical plate portion 61 of the cover 40, the side flange portion 63 after the body 10 is bent formed on the cover 40 side of the base vertical plate portion 64 Therefore, the rigidity of the latch device L around the engaging member mounting shaft 21 can be improved.

It is fixed at several places, the assembling strength is strengthened, and the assembling work to the back sheet 6 is also used to facilitate the work and improve the efficiency.
Thus, the operation transmission member 41 is composed of two cables, the one side cable 41A connected to the one side operation member 42A and the other side cable 41B connected to the other side operation member 42B. The member 42A and the other side operation member 42B can be operated independently by the one side cable 41A and the other side cable 41B.
そのため、一方側操作部材42Aと他方側操作部材42Bは充分離れた箇所に夫々設けられるので、例えば、一方側操作部材42Aは運転座席近傍に設け、他方側操作部材42Bは背凭シート6に設けると、夫々の位置にて操作が可能となって、操作性を向上させられる。
一方側ケーブル41Aと他方側ケーブル41Bは共にアウターチューブ100内にインナーケーブル101を挿通して形成し、アウターチューブ100の一端は前記一方側操作部材42Aと他方側操作部材42Bの近傍所定位置に固定し、インナーケーブル101の一端は一方側操作部材42Aと他方側操作部材42Bに夫々接続しているので、一方側操作部材42Aと他方側操作部材42Bの何れかを操作すると、二本のインナーケーブル101の内の一本を牽引して作動伝達手段(開放用部材)36を作動させる。
For this reason, the one-side operation member 42A and the other-side operation member 42B are provided at positions that are sufficiently separated from each other. For example, the one-side operation member 42A is provided in the vicinity of the driver seat, and the other-side operation member 42B is provided on the back seat 6. Then, the operation can be performed at each position, and the operability can be improved.
Both the one side cable 41A and the other side cable 41B are formed by inserting the inner cable 101 into the outer tube 100, and one end of the outer tube 100 is fixed at a predetermined position in the vicinity of the one side operation member 42A and the other side operation member 42B. Since one end of the inner cable 101 is connected to the one-side operation member 42A and the other-side operation member 42B, when one of the one-side operation member 42A and the other-side operation member 42B is operated, two inner cables One of the members 101 is pulled to operate the operation transmitting means (opening member) 36.
一方側ケーブル41Aと他方側ケーブル41Bのアウターチューブ100の他端は前記装置Lの所定位置に設けたアウタ係止部103に固定状態に取付けているので、可撓性のあるアウターチューブ100を配索して、離れた一方側操作部材42Aおよび他方側操作部材42Bと装置Lの作動伝達手段36とを連結する。
一方側ケーブル41Aと他方側ケーブル41Bの夫々のインナーケーブル101の端部には先端係合部104を夫々設け、一方側ケーブル41Aと他方側ケーブル41Bの夫々の先端係合部104は作動伝達手段36に設けたケーブル係止部105に取付けているので、一方側操作部材42Aと他方側操作部材42Bの何れかを操作すると、二本のインナーケーブル101の内の一本が牽引され、作動伝達手段36に係合している先端係合部104が作動伝達手段36を作動させる。
Since the other end of the outer tube 100 of the one side cable 41A and the other side cable 41B is fixedly attached to the outer locking portion 103 provided at a predetermined position of the device L, the flexible outer tube 100 is arranged. The separated one side operation member 42A and the other side operation member 42B are connected to the operation transmission means 36 of the apparatus L.
A tip engaging portion 104 is provided at each end of the inner cable 101 of the one side cable 41A and the other side cable 41B, and each tip engaging portion 104 of the one side cable 41A and the other side cable 41B is an operation transmitting means. Since one of the one-side operation member 42A and the other-side operation member 42B is operated, one of the two inner cables 101 is pulled to transmit the operation. The tip engaging portion 104 engaged with the means 36 operates the operation transmitting means 36.
この場合、ケーブル係止部105と先端係合部104とは、一方側操作部材42Aと他方側操作部材42Bの何れか一方の操作により、これに対応した一方側ケーブル41Aと他方側ケーブル41Bの何れかの先端係合部104がケーブル係止部105に係合して作動伝達手段36を回動させるので、操作されていない一方側操作部材42Aと他方側操作部材42Bの何れか他方の一方側ケーブル41Aと他方側ケーブル41Bの何れかの先端係合部104はケーブル係止部105に対して非係合状態となる。
そのため、非係合状態の先端係合部104はその場に留まって、係合状態の先端係合部104が作動伝達手段36を作動させる。
In this case, the cable locking portion 105 and the distal end engaging portion 104 are operated by either one of the one side operation member 42A and the other side operation member 42B, and the corresponding one side cable 41A and the other side cable 41B. Since any one of the front end engaging portions 104 engages with the cable locking portion 105 to rotate the operation transmitting means 36, one of the other one of the non-operated one side operation member 42A and the other side operation member 42B. The distal end engaging portion 104 of either the side cable 41A or the other side cable 41B is not engaged with the cable locking portion 105.
Therefore, the disengaged tip engaging portion 104 remains in place, and the engaged tip engaging portion 104 operates the operation transmitting means 36.
先端係合部104は球形状に形成し、ケーブル係止部105には先端係合部104が外れない先端係合部104より小さい一対の一方側挿通孔110および他方側挿通孔111を設けているので、一対の一方側挿通孔110および他方側挿通孔111の夫々に一方側ケーブル41Aと他方側ケーブル41Bのインナーケーブル101を夫々移動自在に挿通すると、一方側操作部材42Aと他方側操作部材42Bの何れかの操作により一方側ケーブル41Aと他方側ケーブル41Bの何れかの先端係合部104がケーブル係止部105に係合して作動伝達手段36を回動させるが、操作されていない一方側操作部材42Aと他方側操作部材42Bの何れか他方の一方側ケーブル41Aと他方側ケーブル41Bの何れかのインナーケーブル101に対して作動伝達手段36はそのまま回動して非係合状態となる。   The distal end engaging portion 104 is formed in a spherical shape, and the cable locking portion 105 is provided with a pair of one side insertion hole 110 and the other side insertion hole 111 which are smaller than the distal end engagement portion 104 where the distal end engagement portion 104 cannot be removed. Therefore, when the inner cable 101 of the one side cable 41A and the other side cable 41B is movably inserted through the pair of one side insertion hole 110 and the other side insertion hole 111, respectively, the one side operation member 42A and the other side operation member 42B, any one of the one end cable 41A and the other end cable 41B engages with the cable locking portion 105 to rotate the operation transmitting means 36, but is not operated. The inner cable 101 of either the one side cable 41A or the other side cable 41B of either the one side operation member 42A or the other side operation member 42B. Operation transmitting means 36 for become disengaged and it rotates.
ケーブル係止部105には、一方側挿通孔110および他方側挿通孔111に連通する係合溝112と、該係合溝112に連通して先端係合部104を嵌合させうる嵌合孔113とを設けているので、一方側ケーブル41Aと他方側ケーブル41Bの各先端係合部104は、嵌合孔113から係合溝112に嵌合させ、各インナーケーブル101を一方側挿通孔110および他方側挿通孔111から突出させる。
ケーブル係止部105は、ベース板部115の先端に係合板部116を略90度に屈曲させ、前記係合板部116にベース板部115と略平行な対向板部117を設け、前記係合板部116には前記一方側挿通孔110および他方側挿通孔111を形成し、前記対向板部117には前記一方側挿通孔110および他方側挿通孔111に連通する係合溝112と該係合溝112に連通して前記先端係合部104を嵌合させうる嵌合孔113とを設けているので、嵌合孔113の横方向から先端係合部104を嵌合させて、インナーケーブル101を係合溝112から一方側挿通孔110または他方側挿通孔111に通す。
The cable locking portion 105 has an engagement groove 112 communicating with the one-side insertion hole 110 and the other-side insertion hole 111, and a fitting hole that can communicate with the engagement groove 112 and fit the tip engagement portion 104. 113, the respective front end engaging portions 104 of the one side cable 41A and the other side cable 41B are fitted into the engaging grooves 112 from the fitting holes 113, and the respective inner cables 101 are fitted into the one side insertion holes 110. And it is made to project from the other side insertion hole 111.
The cable latching portion 105 bends the engagement plate portion 116 at approximately 90 degrees at the distal end of the base plate portion 115, and provides the engagement plate portion 116 with a counter plate portion 117 substantially parallel to the base plate portion 115. The one-side insertion hole 110 and the other-side insertion hole 111 are formed in the portion 116, and the engagement groove 112 communicating with the one-side insertion hole 110 and the other-side insertion hole 111 and the engagement are formed in the opposing plate portion 117. Since there is provided a fitting hole 113 that communicates with the groove 112 and into which the tip engaging portion 104 can be fitted, the tip engaging portion 104 is fitted from the lateral direction of the fitting hole 113 and the inner cable 101 is fitted. Is passed from the engagement groove 112 to the one-side insertion hole 110 or the other-side insertion hole 111.
実施例では、一方側挿通孔110の係合溝112と他方側挿通孔111の係合溝112を下方で交差するように連通させているので、一方のインナーケーブル101の先端係合部104は嵌合孔113から図25において左側の係合溝112を通して一方側挿通孔110に挿通し、他方のインナーケーブル101の先端係合部104は嵌合孔113から図25において右側の係合溝112を通して他方側挿通孔111に挿通している。
前記アウタ係止部103は、ケーブル係止部105の係合板部116の回動方向に対する接線方向の前記装置Lの所定位置に設けているので、インナーケーブル101はアウタ係止部103とケーブル係止部105の間で交差することなく、牽引される。
したがって、二本のインナーケーブル101が絡むことはない。
In the embodiment, since the engagement groove 112 of the one side insertion hole 110 and the engagement groove 112 of the other side insertion hole 111 are communicated so as to cross downward, the distal end engagement portion 104 of one inner cable 101 is The fitting hole 113 is inserted into the one side insertion hole 110 through the left engagement groove 112 in FIG. 25, and the tip engagement portion 104 of the other inner cable 101 is inserted into the right engagement groove 112 from the fitting hole 113 in FIG. Through the other side insertion hole 111.
Since the outer locking portion 103 is provided at a predetermined position of the device L in the tangential direction with respect to the rotation direction of the engagement plate portion 116 of the cable locking portion 105, the inner cable 101 is connected to the outer locking portion 103 and the cable engagement. It is pulled without crossing between the stop portions 105.
Therefore, the two inner cables 101 are not entangled.
即ち、ケーブル係止部105の係合板部116の回動軌跡に対する接線方向にアウタ係止部103を配置しているので、ケーブル係止部105は軸39中心に円弧移動するが、ケーブル係止部105の移動方向をインナーケーブル101の移動方向と略平行方向な方向に近づけることができ、二本のインナーケーブル101が絡む事態の発生を未然に防止する。
即ち、前記アウタ係止部103は、作動部材20がラッチ状態からアンラッチ状態に移動するときの、作動伝達手段36のケーブル係止部105の移動方向に対して交差方向の上方位置のボディ1またはカバー40に設けているので、一方側操作部材42Aまた他方側操作部材42Bを操作すると、インナーケーブル101は上方に牽引され、インナーケーブル101の上方移動によりケーブル係止部105の係合板部116の下面に当接している先端係合部104は上方移動し、先端係合部104の上方移動によりケーブル係止部105は作動伝達手段36を上方回動させる。
That is, since the outer locking portion 103 is arranged in the tangential direction with respect to the rotation trajectory of the engagement plate portion 116 of the cable locking portion 105, the cable locking portion 105 moves in an arc around the shaft 39. The moving direction of the portion 105 can be brought close to a direction substantially parallel to the moving direction of the inner cable 101, and the occurrence of a situation where the two inner cables 101 are entangled can be prevented.
That is, the outer locking portion 103 is the body 1 or the upper position in the crossing direction with respect to the moving direction of the cable locking portion 105 of the operation transmitting means 36 when the operating member 20 moves from the latched state to the unlatched state. Since the cover 40 is provided, when the one side operation member 42A or the other side operation member 42B is operated, the inner cable 101 is pulled upward, and the engagement plate portion 116 of the cable locking portion 105 is moved by the upward movement of the inner cable 101. The tip engaging portion 104 that is in contact with the lower surface moves upward, and the cable engaging portion 105 rotates the operation transmitting means 36 upward by the upward movement of the tip engaging portion 104.
このとき、一方側挿通孔110および他方側挿通孔111は、先端係合部104を通過させない大きさに形成しているため、インナーケーブル101がケーブル係止部105の回動により図28において、左右に振れても、一方側挿通孔110および他方側挿通孔111はこれを許容する(なお、図28はケーブル係止部105の移動状態の理解を容易にするため、一対の先端係合部104が係合板部116の下面に当接させているが、実際の状態を示すものではない。)。
そのため、非操作の先端係合部104のインナーケーブル101は、ケーブル係止部105の一方側挿通孔110または他方側挿通孔111に対して上下せず、先端係合部104を非係合状態に維持させられる。
At this time, since the one side insertion hole 110 and the other side insertion hole 111 are formed in a size that does not allow the tip engagement portion 104 to pass through, the inner cable 101 is rotated in FIG. One side insertion hole 110 and the other side insertion hole 111 allow this even if it is swung to the left or right (note that FIG. 28 shows a pair of tip engagement portions for easy understanding of the movement state of the cable locking portion 105. 104 is in contact with the lower surface of the engagement plate portion 116, but does not indicate an actual state.)
Therefore, the inner cable 101 of the non-operating tip engagement portion 104 does not move up and down with respect to the one side insertion hole 110 or the other side insertion hole 111 of the cable locking portion 105, and the tip engagement portion 104 is not engaged. Maintained.
また、ケーブル係止部105のベース板部115と対向板部117とは左右に所定間隔おいて設けているので、係合板部116の下面に当接してる先端係合部104に対して、その位置に留まっている非係合状態の非操作側の先端係合部104に上方回動するケーブル係止部105の接触を防止する。
また、前記作動伝達手段36の本体123は、前記係合板部116より反ケーブル係止部105側に移動する先端係合部104と干渉しない厚さに形成しているので、作動伝達手段36の本体123がアンラッチ操作により上方回動する際に、操作されずに留まっている先端係合部104が本体123を避けて、本体123が先端係合部104を移動させずに上方回動させられる。
Further, since the base plate portion 115 and the counter plate portion 117 of the cable locking portion 105 are provided at a predetermined interval on the left and right, the tip engagement portion 104 that is in contact with the lower surface of the engagement plate portion 116 is The contact of the cable locking portion 105 that rotates upward to the non-operating tip engaging portion 104 in the non-engaging state that remains in position is prevented.
Further, since the main body 123 of the operation transmitting means 36 is formed to a thickness that does not interfere with the tip engaging portion 104 that moves to the side opposite to the cable locking portion 105 from the engaging plate portion 116, When the main body 123 is rotated upward by an unlatching operation, the tip engaging portion 104 that remains unoperated avoids the main body 123, and the main body 123 is rotated upward without moving the tip engaging portion 104. .
そのため、側面視において、操作されずに留まっている先端係合部104と作動伝達手段36の本体123とが重なる位置でも、作動伝達手段36を上方回動させることができ、インナーケーブル101の牽引する操作量を増加させることができ、操作者の操作感を向上させられる。
即ち、操作者は、一方側操作部材42Aまたは他方側操作部材42Bの操作量がある程度ないと、操作完了の実感がわかず、どうしても、インナーケーブル101を余分に引く傾向があるので、インナーケーブル101を牽引しうるストロークを十に確保すると、操作者の操作に満足感を与え、操作感を向上させられる。
Therefore, the operation transmission means 36 can be rotated upward even at a position where the tip engaging portion 104 that is not operated and the main body 123 of the operation transmission means 36 overlap each other in a side view, and the inner cable 101 is pulled. The amount of operation to be performed can be increased, and the operational feeling of the operator can be improved.
That is, if the operator does not have a certain amount of operation of the one-side operation member 42A or the other-side operation member 42B, the operator does not feel the completion of the operation and inevitably tends to pull the inner cable 101 excessively. When secured enough stroke that can lead the, giving satisfaction to the operator's operation, it is to improve the operational feeling.
しかして、前記操作伝達部材41の装置の操作機構は、種々の機器に使用(応用)できるが、本願では、前記装置Lを、車両用シート1の背凭シート6と車体3のと間に設けた前記背凭シート6を所定位置に保持するラッチ装置Lとしているので、背凭シート6から離れた一方側操作部材42Aにより操作ができ、操作性および作業性を向上させられる。
また、操作伝達部材41をケーブルとし、先端係合部104をケーブル係止部105に係合させればよいので、ケーブル係止部105の大きさを小型にでき、装置L全体も小型化できる。
また、ケーブル係止部105は金属板部材を屈曲形成し、ケーブル係止部105に一方側挿通孔110〜嵌合孔113を形成し、このケーブル係止部105を樹脂部材の作動伝達手段36の本体123に埋め込むように、所謂インサート成形等により一体形成できるので、製造も容易で、安価にできる。
Thus, the operation mechanism of the device of the operation transmission member 41 can be used (applied) to various devices. In the present application, the device L is disposed between the back seat 6 of the vehicle seat 1 and the vehicle body 3. Since the provided backrest seat 6 is a latch device L that holds the backrest seat 6 in a predetermined position, it can be operated by the one-side operation member 42A separated from the backrest seat 6, and the operability and workability can be improved.
Further, since the operation transmitting member 41 may be a cable and the front end engaging portion 104 may be engaged with the cable locking portion 105, the size of the cable locking portion 105 can be reduced, and the entire apparatus L can be reduced in size. .
The cable locking portion 105 is formed by bending a metal plate member, and the one side insertion hole 110 to the fitting hole 113 are formed in the cable locking portion 105. The cable locking portion 105 is connected to the operation transmission means 36 of the resin member. Since it can be integrally formed by so-called insert molding or the like so as to be embedded in the main body 123, manufacturing is easy and inexpensive.
