Description

【０００１】
【発明の属する技術分野】
本発明は、シート不使用時において該シートを車体に形成した収納凹部に簡単に収納することができる自動車用シートの収納構造に関するものである。
【０００２】
【従来の技術】
従来から、この種のシート収納構造として、例えば特開平１１−４８８４０号公報や実開平５−４００２９号公報等に開示されるように、シートクッションとシートバックからなるシートをその後方の車体フロアに形成した収納凹部に収納できるようにしたものが知られている。
【０００３】
しかしながら、従来のものはシートを収納凹部に収納した状態で車を運転すると、車からの振動で収納したシートが上下動してしまいガタ等の異音を発生させたり、シート上に載置してある荷物を静かに保管することができない等の問題点があった。
【０００４】
【発明が解決しようとする課題】
本発明は上記のような従来の問題点を解決して、収納凹部に収納された重ね合わせシートを定位置にしっかりと固定することができ、また収納したシートの固定およびその解除の操作もきわめて簡単に行うことができる自動車用シートの収納構造を提供することを目的として完成されたものである。
【０００５】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の自動車用シートの収納構造は、シートクッションとシートバックからなるシートをシートクッションの座面に向けシートバックを伏倒させて重ね合わせた状態とし、この重ね合わせシートをシート後方の車体フロアに形成した収納凹部に前記シートクッションと車体フロアとを連繋しているリンク部材を介して収納できるようにした自動車用シートの収納構造において、前記リンク部材はその前後両端部をそれぞれヒンジとヒンジとを介してシートクッションと車体フロアとに連結されたものであり、かつシートクッションのフレームの下面に設けたフック部材と、収納凹部の底面に設けたストライカー部材とによって、収納凹部内に収納したシートを固定するロック機構を構成しており、前記リンク部材のフロア側連結部に、このリンク部材と収納凹部の底部との開き角度を常時拡開される方向に弾発するスプリング、およびリンク部材とシートクッションとの開き角度を常時拡開される方向に弾発するスプリングを設け、また前記フック部材とストライカー部材とを収納状態のシートの前記ヒンジとヒンジ間に位置させたことを特徴とするものである。
【０００６】
【発明の実施の形態】
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３列目に設けた自動車用シートに適用した場合を示すものであって、シートクッション１ａとシートバック１ｂからなるシート１をシートクッション１ａの座面に向けシートバック１ｂを伏倒させて重ね合わせ状態とし、この重ね合わせシート１を、シートクッション１ａの後部と車体フロア２０とを連繋するリンク部材１０を介して、シート後方の車体フロア２０に形成した収納凹部２に収納するようにしたものであり、本発明では前記収納したシートを固定するロック機構３が設けられたものとなっている。
【０００７】
前記ロック機構３は、図１に示されるように、シートクッション１ａのフレームの下面に設けたフック部材３ａと、収納凹部２の底面に設けたストライカー部材３ｂとが係合するものとなっており、重ね合わせシート１をロック機構３で固定した場合、シートバック１ｂの裏面側が車体フロア２０とフラットな同一を形成するよう構成されている。
また、このロック機構３としては、例えばフック部材３ａにシート後方に延びるケーブルやリンク等の連結部材の一端を設けるとともに、シートクッション後方に軸着されたリンクの中間部に前記連結部材の他端を回転可能に取り付け、リンク部材の自由端部に後方に延びる帯を設けて、該帯を後方に引くことでロックを解除するようにしたものを用いることができる。
このような構成とすることにより、収納凹部２に収納された重ね合わせシートを定位置にしっかりと固定することができ、また収納したシートの固定およびその解除の操作もきわめて簡単に行うことができるのである。
【０００８】
また、図２に示されるように、前記したリンク部材１０のフロア側連結部には、このリンク部材１０と収納凹部２の底部との開き角度αを常時拡開される方向に弾発するスプリング５が設けられており、また、リンク部材１０のシート側連結部にこのリンク部材１０とシートクッション１ａの横面との開き角度βを常時拡開される方向に弾発するスプリング６が設けられていて、このような構造とすることで、後述するように、収納凹部２に収納された重ね合わせシート１を収納状態から使用状態へ移動させようとして引き上げる場合、前記したスプリング５、６の弾発力の作用により上向きに引き上げられた状態となっている重ね合わせシート１の引き上げ操作を極めて容易に行うことができ、また、重ね合わせシート１を収納凹部２に収納する場合も、前記スプリング５、６の弾発力の作用により急激な落ち込みが防止され安全に操作できる。更には、収納凹部２に収納された重ね合わせシート１に上向きの弾発力を作用することで、前記ロック機構３の解除を確実なものとしている。
【０００９】
なお、図２に示すものはリンク部材１０のフロア側連結部にスプリング５を設けるとともにシート側連結部の双方にもスプリング６を設けているが、リンク部材１０のフロア側連結部にのみスプリング５を設けるようにしたり（図１参照）、逆にシート側連結部にのみスプリング６を設けるようにしてもよい。要は、収納凹部２に収納された重ね合わせシート１をスプリングの作用を借りて小さな力で簡単に引き出すことができるうえに、シートクッション１ａの座面に向けシートバック１ｂを伏倒させて重ね合わせたシート１を収納凹部２に収納する場合に、急激な落ち込みを無くすようにスプリングで支えながら徐々に収納されるようにできればよい。また、前記した開き角度拡開用のスプリング５、６は、図示のものでは、スプリング５がコイルバネ、スプリング６が渦巻きバネを用いたものとなっており、各々矢印方向の弾発力を付与しシート１に対して常に上向きの力を作用しているが、スプリングの種類としては同様の作用をするものであればいかなる物も用いることができることは勿論である。
【００１０】
また、前記したリンク部材１０は、Ｌ字状の部材からなり一端がシートクッション１ａの後部にヒンジ１０ａを介して回転自在に連結され、他端が収納凹部２の底部前方にヒンジ１０ｂを介して回転自在に連結されたものであり、このヒンジ１０ｂを中心にリンク部材１０が回動することによりシート１が座席を形成する状態と、収納凹部２内に収納された状態の２態様を採るよう構成されている。
【００１１】
このリンク部材１０は、全体は平面視した場合にコ字状枠の一体に形成されたものとなっており、このように、従来のようにリンク部材が棒状体であって、単にシートクッション１ａの下面後部と収納凹部２の底面前方部とを連結したものでないため、重ね合わせシート１の移動時において回転やグラツキを生じることがなく、安定した状態でシートの持ち上げ作業等を行うことができる。
【００１２】
さらに、リンク部材１０とシートクッション１ａの間には、収納凹部２に収納される重ね合わせシート１を略水平状態に保持するための弾発部材７を張設してあり、この弾発部材７と前記したスプリング５、６がシートの荷重に対してバランスをとるように作用することで、重ね合わせシート１が常に水平状態に保持され易くなるように構成されている。また、この弾発部材７はシート１が使用状態に戻るにつれてリンク部材１０がシートクッション１ａの後方に回転することにより引き伸ばされ、使用状態方向への付勢力を増加する作用もあり、シート１を収納状態から使用状態へ移行する際に安定した操作力の補助を受けることができ、操作性がよくなる。なお、前記弾発部材７としては、流体圧を利用したダンパやコイルスプリング等を用いることができる。
【００１３】
なお、図において８は、シートクッション１ａの下面前部に設けられた前脚であり、シートとして使用する時は車体フロア２０に設けたストライカー８ａに係合して固定し、シート収納時には邪魔にならないようシートクッション１ａ内へ畳むよう構成されている。
【００１４】
このように構成したものは、収納したシートを固定するロック機構３が設けられているとともに、該ロック機構３の解除は遠隔操作により行えるように構成されているので、収納凹部２に収納された重ね合わせシートを定位置にしっかりと固定することができ、また収納したシートの固定およびその解除の操作もきわめて簡単に行うことができることとなる。また、リンク部材１０がその一端をシートクッション１ａの後部に回転自在に連結させ、他端を収納凹部２に回転自在に連結させているだけではなく、このリンク部材１０のシート側連結部およびフロア側連結部のいずれか一方または双方には、各々開き角度拡開用のスプリングを配設したものとした場合は、図２に示されるように、スプリング５、６の弾発力によりシート１には常に上向きの力が作用した状態となっており、従って、重ね合わせシート１を収納状態から使用状態へ移動させようとして引き上げる場合には、小さな力で簡単にシート１を持ち上げることができ、極めて容易に引き上げ操作を行うことができることとなる。一方、シート１を収納凹部２へ移動させる場合にも、前記スプリング５、６の弾発力の作用により急激な落ち込みが防止されるので極めて安全に操作できることとなる。なお、このような開き角度拡開用のスプリング５、６を配置した場合であっても、前記ロック機構３によって重ね合わせシートを収納凹部２の定位置にしっかりと固定することができるため、図１に示されるように、シートを収納凹部２内に完全に折り畳んだ状態（即ち、最小の高さの状態）として収納することができ、従って特別に深さのある収納凹部２とする必要もなくコンパクトな設計が可能である。
また、シートの収納時において、ロック機構３のフック部材３ａが設けられたシート（シートクッション１ａのフレーム）は常時上方向きに付勢された状態となっているため、前記フック部材３ａとストライカー３ｂのガタの発生も抑えることができることとなる。
【００１５】
また、リンク部材１０とシートクッション１ａの間にシート１をシート１が使用状態に戻るにつれて使用状態方向への付勢力を増加するようにする弾発部材７を張設してある場合は、シート１を収納状態から使用状態へ移動させようとして引き上げた場合に、前記使用状態方向への付勢力が作用して小さな力で簡単にシート１を持ち上げることができ、極めて容易に引き上げ操作を行うことができることとなる。即ち、弾発部材７の付勢力は、シート１が使用状態に戻るにつれスプリング５、６のシートを持ち上げる付勢力が低下するが、この低下分を補う形でシート１を持ち上げる作用を発揮するものであり、シート１を収納状態から使用状態へ移動させようとして引き上げた際に、常に一定の引き上げ力を与えるため、優れた取扱性を発揮できることとなる。
【００１６】
なお、シート１の収納操作は、シートバック１ｂをシートクッション１ａ側に折り畳むとともに前脚８の固定を解除し、この状態のままリンク部材１０を後方側へ回転して収納凹部２内へ移動して収納するものであり、一方、シート１を取り出す操作は、前記と逆の操作を行うのみで、いずれも簡単な操作で行えるものである。
【００１７】
【発明の効果】
以上の説明からも明らかなように、本発明は収納凹部に収納された重ね合わせシートを定位置にしっかりと固定することができて走行中における異音の発生等を防止することができ、また収納したシートの固定およびその解除の操作もきわめて簡単に行うことができて優れた操作性を発揮することができるものである。更には、リンク部材の連結部にスプリングを設けたものでは、シートクッションの座面に向けシートバックを伏倒させた重ね合わせシートを車体フロアに形成してある収納凹部に収納する場合も急激な落ち込みがなく安全に操作することができる利点がある。
よって本発明は従来の問題点を一掃した自動車用シートの収納構造として、産業の発展に寄与するところは極めて大である。

And a hook member and a striker member are positioned between the hinges of the seat in the stored state .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawings show the case where the present invention is applied to an automobile seat provided in the third row, in which the seat 1 comprising the seat cushion 1a and the seat back 1b is directed to the seating surface of the seat cushion 1a. The stacked seat 1 is placed in a folded state and stored in a storage recess 2 formed on the vehicle body floor 20 behind the seat via a link member 10 that connects the rear portion of the seat cushion 1a and the vehicle floor 20. In the present invention, a lock mechanism 3 for fixing the stored sheet is provided.
[0007]
As shown in FIG. 1, the locking mechanism 3 engages a hook member 3 a provided on the lower surface of the frame of the seat cushion 1 a and a striker member 3 b provided on the bottom surface of the storage recess 2. When the overlapping sheet 1 is fixed by the lock mechanism 3, the back side of the seat back 1 b is configured to form the same flatness as the vehicle body floor 20.
In addition, as the locking mechanism 3, for example, one end of a connecting member such as a cable or a link extending rearward of the seat is provided on the hook member 3a, and the other end of the connecting member is provided at an intermediate portion of the link pivotally attached to the rear of the seat cushion. It is possible to use a structure in which a belt extending backward is provided at the free end of the link member and the lock is released by pulling the belt backward.
With such a configuration, the stacked sheets stored in the storage recess 2 can be firmly fixed at a fixed position, and the stored sheets can be fixed and released very easily. It is.
[0008]
Further, as shown in FIG. 2, the floor 5 connecting portion of the link member 10 has a spring 5 that repels the opening angle α between the link member 10 and the bottom portion of the storage recess 2 in a direction that is always expanded. In addition, a spring 6 is provided at the seat side connecting portion of the link member 10 to repel the opening angle β between the link member 10 and the lateral surface of the seat cushion 1a in a direction in which the link member 10 is always expanded. By adopting such a structure, as will be described later, when the superposed sheet 1 stored in the storage recess 2 is pulled up to move from the stored state to the used state, the elasticity of the springs 5 and 6 described above is used. The operation of pulling up the overlapping sheet 1 that has been pulled upward by the action of the above can be performed very easily, and the overlapping sheet 1 is stored in the storage recess 2. In this case, the springs 5 and 6 can be operated safely by preventing the sudden drop due to the elastic force. Further, the lock mechanism 3 is reliably released by applying an upward elastic force to the overlapping sheet 1 stored in the storage recess 2.
[0009]
2, the spring 5 is provided at the floor side connecting portion of the link member 10 and the spring 6 is provided at both of the seat side connecting portions. However, the spring 5 is provided only at the floor side connecting portion of the link member 10. Alternatively, the spring 6 may be provided only at the seat side connecting portion. In short, the overlapping sheet 1 stored in the storage recess 2 can be pulled out easily with a small force using the action of a spring, and the seat back 1b is laid down on the seating surface of the seat cushion 1a. When the combined sheet 1 is stored in the storage recess 2, it may be stored gradually while being supported by a spring so as to eliminate a sudden drop. In addition, the springs 5 and 6 for expanding the opening angle described above are those using a coil spring and a spring 6 using a spiral spring in the illustrated one, and each provides a resilient force in the direction of the arrow. Although an upward force is always applied to the seat 1, any kind of spring can be used as long as it has the same action.
[0010]
The link member 10 is an L-shaped member, and one end of the link member 10 is rotatably connected to the rear portion of the seat cushion 1a via a hinge 10a, and the other end is connected to the front of the bottom of the storage recess 2 via a hinge 10b. The link member 10 is pivotally connected around the hinge 10b so that the seat 1 forms a seat, and the seat 1 is stored in the storage recess 2. It is configured.
[0011]
The link member 10 is formed integrally with a U-shaped frame when viewed in plan, and thus the link member is a rod-like body as in the prior art, and is simply a seat cushion 1a. Since the rear surface of the lower surface and the front portion of the bottom surface of the storage recess 2 are not connected to each other, the sheet can be lifted in a stable state without causing rotation or unevenness when the overlapping sheet 1 is moved. .
[0012]
Further, a resilient member 7 is held between the link member 10 and the seat cushion 1a to hold the overlapping sheet 1 stored in the storage recess 2 in a substantially horizontal state. The above-described springs 5 and 6 act so as to balance the load of the sheet, so that the superposed sheet 1 is always easily held in a horizontal state. Further, the elastic member 7 is stretched by the link member 10 being rotated rearward of the seat cushion 1a as the seat 1 returns to the use state, and has an effect of increasing the urging force in the use state direction. When shifting from the storage state to the use state, it is possible to receive stable operation force assistance, and the operability is improved. As the elastic member 7, a damper or a coil spring using fluid pressure can be used.
[0013]
In the figure, reference numeral 8 denotes a front leg provided at the front part of the lower surface of the seat cushion 1a. When used as a seat, the front leg is engaged with and fixed to a striker 8a provided on the vehicle body floor 20, and does not get in the way when the seat is stored. It is comprised so that it may fold into the seat cushion 1a.
[0014]
In this configuration, the lock mechanism 3 for fixing the stored sheet is provided, and the lock mechanism 3 can be released by remote operation. Therefore, the lock mechanism 3 is stored in the storage recess 2. The stacked sheets can be firmly fixed in place, and the operation of fixing and releasing the stored sheets can be performed very easily. The link member 10 not only has one end rotatably connected to the rear part of the seat cushion 1a and the other end rotatably connected to the storage recess 2, but also the link side 10 of the link member 10 and the floor When one or both of the side connecting portions are provided with springs for widening the opening angle, as shown in FIG. 2, the elastic force of the springs 5 and 6 causes the seat 1 to Is always in a state where an upward force is applied. Therefore, when pulling up the superimposed sheet 1 to move it from the stored state to the use state, the sheet 1 can be easily lifted with a small force. The lifting operation can be easily performed. On the other hand, even when the seat 1 is moved to the storage recess 2, since the sudden drop is prevented by the action of the elastic force of the springs 5, 6, it can be operated extremely safely. Even when the springs 5 and 6 for widening the opening angle are disposed, the overlap sheet can be firmly fixed to a fixed position of the storage recess 2 by the lock mechanism 3. 1, the sheet can be stored in the storage recess 2 in a completely folded state (that is, at a minimum height), and therefore, it is necessary to make the storage recess 2 have a special depth. A compact design is possible.
Further, when the seat is stored, the seat provided with the hook member 3a of the lock mechanism 3 (the frame of the seat cushion 1a) is always urged upward, so the hook member 3a and the striker 3b The occurrence of backlash can also be suppressed.
[0015]
Further, when a resilient member 7 is provided between the link member 10 and the seat cushion 1a so as to increase the urging force in the direction of use as the seat 1 returns to the use state, the seat 1 When the seat 1 is pulled up to move from the stored state to the use state, the urging force in the use state direction acts and the seat 1 can be lifted easily with a small force, and the pulling operation is performed very easily. Will be able to. In other words, the urging force of the elastic member 7 decreases the urging force of lifting the springs 5 and 6 as the sheet 1 returns to the use state, and exerts the action of lifting the sheet 1 to compensate for this decrease. Thus, when the sheet 1 is pulled up to move from the housed state to the used state, a constant lifting force is always applied, so that excellent handleability can be exhibited.
[0016]
The seat 1 is stored by folding the seat back 1b to the seat cushion 1a side and releasing the fixing of the front leg 8, and rotating the link member 10 rearward in this state to move into the storage recess 2. On the other hand, the operation of taking out the sheet 1 can be performed by a simple operation only by performing an operation reverse to the above.
[0017]
【The invention's effect】
As is clear from the above description, the present invention can firmly fix the overlapping sheet stored in the storage recess in a fixed position, and can prevent the occurrence of abnormal noise during traveling, The operation of fixing and releasing the stored sheet can be performed very easily, and excellent operability can be exhibited. Furthermore, in the case where a spring is provided at the connecting portion of the link member, a sudden change occurs when the overlapping seat with the seat back lying down toward the seat surface of the seat cushion is stored in the storage recess formed on the vehicle body floor. There is an advantage that it can be operated safely without depression.
Therefore, the present invention contributes greatly to the development of the industry as an automotive seat storage structure that eliminates the conventional problems.
