Description

この発明は、外部からの荷重入力に対して乗員を保護する機能を備えた車両用シートに関するものである。   The present invention relates to a vehicle seat having a function of protecting an occupant against load input from the outside.

車両用シートの多くは、側方からの荷重入力をフレーム枠で剛的に受け止める構造を持たないため、車両側面衝突時にシート自体で衝突エネルギーを効率良く受け止めることができない。   Many of the vehicle seats do not have a structure that rigidly receives the load input from the side by the frame frame, and therefore, the collision energy cannot be received efficiently by the seat itself at the time of a vehicle side collision.

このため、これに対処する車両用シートとして、シートクッションの左右の支持ブラケットに両支持ブラケットを連結するシートクロスメンバを設け、このシートクロスメンバの端部を車体幅方向外側に突出させて、車両側面衝突時にシートクロスメンバで荷重を受け止めるようにしたものが案出されている。
特開平９−９５１９６号公報 For this reason, as a vehicle seat to cope with this, a seat cross member that couples both support brackets to the left and right support brackets of the seat cushion is provided, and an end portion of the seat cross member protrudes outward in the vehicle body width direction. There has been devised one in which a load is received by a seat cross member at the time of a side collision.
JP-A-9-95196

しかし、この従来の車両用シートにおいては、支持ブラケット上の乗員の保護を要する部位にシートクロスメンバを設け、そのシートクロスメンバの剛性のみで衝突荷重を受け止めるようになっているため、車両側面衝突時に、シート側方に充分な乗員保護空間を確保するためには、シートクロスメンバの先端部の突出量を大きくする必要があるが、突出量を大きくすると日常使用時におけるシートの利便性が低下するという別の不具合を招く。   However, in this conventional vehicle seat, a seat cross member is provided in a portion of the support bracket that requires protection of the occupant, and the collision load is received only by the rigidity of the seat cross member. Sometimes it is necessary to increase the amount of protrusion at the front end of the seat cross member in order to ensure sufficient passenger protection space on the side of the seat. However, increasing the amount of protrusion reduces the convenience of the seat during daily use. This leads to another problem.

そこでこの発明は、日常使用時の利便性低下を招くことなく、車両側面衝突時に側方に充分な乗員保護空間を確保できる車両用シートを提供しようとするものである。   Therefore, the present invention is intended to provide a vehicle seat that can secure a sufficient passenger protection space on the side in the event of a vehicle side collision without causing a decrease in convenience during daily use.

上記の課題を解決する請求項１に記載の発明は、シートフレーム（例えば、後述の実施形態におけるクッションフレーム５Ａおよびバックフレーム７Ａ）の車体幅方向外側に、車体幅方向外側から荷重を受ける荷重受け部（例えば、後述の実施形態におけるピストン６）と、車体幅方向外側に押圧荷重を作用させる押圧部（例えば、後述の実施形態におけるピストン８）を離間して設けるとともに、前記荷重受け部に作用する荷重を前記押圧部に伝達する荷重伝達部（例えば、後述の実施形態における流体配管１０）を設けたことを特徴とする。
これにより、車両側面衝突時に、サイドドア等を通して荷重受け部に荷重が入力されると、その荷重は荷重伝達部を通して押圧部に伝達され、押圧部が車体幅方向外側に押圧荷重を作用させるようになる。これにより、サイドドア等が押圧部によって押圧され、シートの側方に乗員保護空間が確保される。 The invention according to claim 1, which solves the above problem, is a load receiver that receives a load from the outside in the vehicle body width direction on the outside in the vehicle body width direction of the seat frame (for example, a cushion frame 5A and a back frame 7A in an embodiment described later). A portion (for example, a piston 6 in an embodiment described later) and a pressing portion (for example, a piston 8 in an embodiment described later) for applying a pressing load to the outer side in the vehicle body width direction are provided apart from each other and acts on the load receiving portion. The load transmission part (for example, fluid piping 10 in the below-mentioned embodiment) which transmits the load to perform to the said press part is provided.
Thus, when a load is input to the load receiving portion through the side door or the like at the time of a vehicle side collision, the load is transmitted to the pressing portion through the load transmitting portion, so that the pressing portion applies a pressing load to the outer side in the vehicle body width direction. become. Thereby, a side door etc. are pressed by the press part, and a passenger | crew protection space is ensured in the side of a sheet | seat.

請求項２に記載の発明は、請求項１に記載の車両用シートにおいて、前記荷重受け部と押圧部を進退自在なピストン（例えば、後述の実施形態におけるピストン６，８）によって構成し、前記荷重伝達部を流体を充填した流体配管（例えば、後述の実施形態における流体配管１０）によって構成したことを特徴とする。
これにより、荷重受け部側のピストンに衝突荷重が入力されると、流体配管内の流体が押圧部側のピストンを押圧するようになる。 According to a second aspect of the present invention, in the vehicle seat according to the first aspect, the load receiving portion and the pressing portion are configured by pistons (for example, pistons 6 and 8 in embodiments described later), The load transmission unit is configured by a fluid pipe (for example, a fluid pipe 10 in an embodiment described later) filled with a fluid.
Accordingly, when a collision load is input to the piston on the load receiving portion side, the fluid in the fluid piping presses the piston on the pressing portion side.

請求項３に記載の発明は、請求項２に記載の車両用シートにおいて、前記押圧部のピストンの受圧面積を前記荷重受け部のピストンの受圧面積よりも大きくしたことを特徴とする。
これにより、押圧部のピストンは、荷重受け部側のピストンに作用する力に対して大きな力でサイドドア等を押し返すようになる。 According to a third aspect of the present invention, in the vehicle seat according to the second aspect, the pressure receiving area of the piston of the pressing portion is larger than the pressure receiving area of the piston of the load receiving portion.
Thereby, the piston of a press part comes to push back a side door etc. with big force with respect to the force which acts on the piston of the load receiving part side.

請求項１に記載の発明によれば、車体幅方向外側の荷重受け部で受けた荷重を荷重伝達部を通して押圧部に作用させ、押圧部でサイドドア等を積極的に押し返すことができるため、日常使用時に荷重受け部や押圧部を車体幅方向に大きく突出させることなく、車両側面衝突時に乗員保護空間を充分に確保することができる。   According to the first aspect of the invention, the load received by the load receiving portion on the outer side in the vehicle body width direction can be applied to the pressing portion through the load transmitting portion, and the side door can be positively pushed back by the pressing portion. A passenger protection space can be sufficiently secured at the time of a vehicle side collision without causing the load receiving portion and the pressing portion to protrude greatly in the vehicle body width direction during daily use.

請求項２に記載の発明によれば、流体配管内に充填した流体を利用して荷重受け部に作用した荷重を押圧部に伝達するため、荷重受け部や押圧部を比較的自由な位置に配置することができる。   According to the second aspect of the present invention, the load acting on the load receiving portion is transmitted to the pressing portion using the fluid filled in the fluid piping, so that the load receiving portion and the pressing portion are placed in a relatively free position. Can be arranged.

請求項３に記載の発明によれば、押圧部のピストンの受圧面積を荷重受け部のピストンの受圧面積よりも大きくしたため、入力荷重よりも大きな押圧力でもって車体側方を押し返すことができ、乗員保護空間を確保するのにより有利となる。   According to the invention of claim 3, since the pressure receiving area of the piston of the pressing portion is larger than the pressure receiving area of the piston of the load receiving portion, the vehicle body side can be pushed back with a pressing force larger than the input load. It is more advantageous to secure a passenger protection space.

以下、この発明の各実施形態を図面に基づいて説明する。なお、以下の説明において、「上」「下」は、特別に断らない限り車体に対して上下を指すものとする。また、各実施形態において、同一部分には同一符号を付し、重複する説明を省略するものとする。
最初に、図１〜図４に示すこの発明の第１の実施形態について説明する。
図１は、この実施形態の車両用シート１を示す斜視図であり、図２は、この車両用シートの断面図である。これらの図に示すように車両用シート１は、乗員の臀部および大腿部が載せ置かれるシートクッション２と、乗員の腰部から肩部にかけてを支持するシートバック３とを備え、シートバック３の下端がリクライニングシャフト４を介してシートクッション２の後端部に傾動可能に支持されている。そして、シートクッション２の車体幅方向外側のクッションフレーム５Ａには、荷重受け用のピストン６（荷重受け部）が進退自在に支持され、シートバック３の車体幅方向外側のバックフレーム７Ａには、押圧用のピストン８（押圧部）が進退自在に支持されている。両ピストン６，８の車体幅方向外側の端部には当接フランジ６ａ，８ａが設けられ、これらの各当接フランジ６ａ，８ａが、図２に示すように、サイドドア９の車室内側面に設定間隔を隔てて対峙している。荷重受け用のピストン６とサイドドア９の離間幅Ｄ１は、押圧用のピストン８とサイドドア９の離間幅Ｄ２よりも狭く設定されている。 Embodiments of the present invention will be described below with reference to the drawings. In the following description, “upper” and “lower” refer to up and down with respect to the vehicle body unless otherwise specified. Moreover, in each embodiment, the same code | symbol is attached | subjected to the same part and the overlapping description shall be abbreviate | omitted.
First, a first embodiment of the present invention shown in FIGS. 1 to 4 will be described.
FIG. 1 is a perspective view showing a vehicle seat 1 of this embodiment, and FIG. 2 is a cross-sectional view of the vehicle seat. As shown in these drawings, the vehicle seat 1 includes a seat cushion 2 on which the occupant's buttocks and thighs are placed, and a seat back 3 that supports the occupant's waist and shoulders. The lower end of the seat cushion 2 is supported via the reclining shaft 4 so as to be tiltable. A load receiving piston 6 (load receiving portion) is supported on the cushion frame 5A on the outer side in the vehicle body width direction of the seat cushion 2 so as to freely advance and retreat, and on the back frame 7A on the outer side in the vehicle body width direction of the seat back 3, A pressing piston 8 (pressing portion) is supported so as to freely advance and retract. Abutting flanges 6a and 8a are provided at the outer ends of the pistons 6 and 8 in the vehicle width direction, and these abutting flanges 6a and 8a are provided on the side surfaces of the side door 9 in the vehicle interior as shown in FIG. Are facing each other with a set interval. The separation width D1 between the load receiving piston 6 and the side door 9 is set to be narrower than the separation width D2 between the pressing piston 8 and the side door 9.

また、シートクッション２とシートバック３には、流体が充填された流体配管１０（荷重伝達部）が渡され、その流体配管１０の両端部に荷重受け用のピストン６と押圧用のピストン８が夫々摺動自在に嵌合され、両ピストン６，８の進退作動が内部の流体を通して連動するようになっている。この実施形態の場合、流体配管１０は、車体幅方向外側と内側のクッションフレーム５Ａ，５Ｂ（シートフレーム）間に配管されるクッション内配管１０ａと、車体幅方向外側と内側のバックフレーム７Ａ，７Ｂ（シートフレーム）間に配管されるバック内配管１０ｂと、車体幅方向内側のクッションフレーム５Ｂとバックフレーム７Ｂの外部において両配管１０ａ，１０ｂ同士を連結する接続配管１０ｃとから構成されている。   Further, a fluid piping 10 (load transmitting portion) filled with fluid is passed to the seat cushion 2 and the seat back 3, and a load receiving piston 6 and a pressing piston 8 are provided at both ends of the fluid piping 10. Each of the pistons 6 and 8 is slidably fitted so that the forward and backward movements of the pistons 6 and 8 are linked through the internal fluid. In the case of this embodiment, the fluid pipe 10 includes a cushion inner pipe 10a that is piped between the outer and inner cushion frames 5A and 5B (seat frames), and the outer and inner back frames 7A and 7B. It is composed of a back-inside pipe 10b piped between the (seat frames), a cushion frame 5B on the inner side in the vehicle body width direction, and a connection pipe 10c for connecting the pipes 10a, 10b to each other outside the back frame 7B.

なお、流体配管１０に充填される流体は、非圧縮性流体である液体であることが望ましく、その中でも、充分な潤滑性と流動性を有し、化学的に安定で錆や腐食の発生を防止でき、シール剤との適合性が良いものが好ましい。   The fluid filled in the fluid pipe 10 is preferably a liquid that is an incompressible fluid, and among them, it has sufficient lubricity and fluidity, is chemically stable, and generates rust and corrosion. Those that can be prevented and have good compatibility with the sealant are preferred.

以上の構成において、この車両用シート１を採用した車両の側面に別の車両が衝突し、その衝突によって図３に仮想線で示すようにサイドドア９が車室内側に迫り出してくると、サイドドア９は最初に離間幅の狭い荷重受け用のピストン６のフランジ６ａに当接し、そのピストン６を車室内方向に押し込む。そして、こうして荷重受け用のピストン６が押し込まれると、流体配管１０内の流体の圧力が高まって押圧用のピストン８を突出方向に押し出し、車室内方向に迫り出してくるサイドドア９を車体幅方向外側に押し返す。   In the above configuration, when another vehicle collides with the side surface of the vehicle employing the vehicle seat 1, and the side door 9 approaches the vehicle interior side as shown by the phantom line in FIG. The side door 9 first comes into contact with the flange 6a of the load receiving piston 6 having a small separation width, and pushes the piston 6 toward the vehicle interior. Then, when the load receiving piston 6 is pushed in this way, the pressure of the fluid in the fluid pipe 10 is increased to push the pushing piston 8 in the protruding direction, and the side door 9 that pushes out in the vehicle interior direction is moved to the vehicle body width. Push it back in the direction.

こうして、押圧用のピストン８がサイドドア９を押し返すと、シートバック３の側部に充分な空間を確保でき、衝突荷重が大きく、たとえ、充分な空間を確保し続けることができない場合でもサイドドア９の迫り出しを遅らせることができる。   Thus, when the pressing piston 8 pushes back the side door 9, a sufficient space can be secured in the side portion of the seat back 3, the collision load is large, and even when the sufficient space cannot be secured, the side door can be secured. You can delay 9 pushes.

そして、サイドドア９からの入力荷重がさらに高まった場合には、図４に示すように荷重受け用のピストン６と押圧用のピストン８がともにサイドドア９によって押し込まれるようになるが、このときには、流体配管１０全体で圧力を受けて衝突荷重を受け止めるようになる。   When the input load from the side door 9 further increases, the load receiving piston 6 and the pressing piston 8 are both pushed by the side door 9 as shown in FIG. The entire fluid pipe 10 receives pressure and receives a collision load.

以上のように、この車両用シート１においては、車体幅方向外側のクッションフレーム５Ａの荷重受け用のピストン６で受けた衝突荷重を、流体配管１０内の流体を介して押圧用のピストン８に作用させ、その押圧用のピストン８でバックフレーム７Ａの側部でサイドドア９を押し返すことができるため、ピストン６，８を予め大きく突出させておくことなく衝突時には乗員保護空間を充分に確保することができる。したがって、日常使用時にピストン６，８が邪魔にならず、車両用シート１の利便性を犠牲にすることもない。   As described above, in the vehicle seat 1, the collision load received by the load receiving piston 6 of the cushion frame 5 </ b> A on the outer side in the vehicle body width direction is applied to the pressing piston 8 via the fluid in the fluid pipe 10. The side door 9 can be pushed back by the side of the back frame 7A with the piston 8 for pressing, so that a sufficient passenger protection space is ensured at the time of collision without causing the pistons 6 and 8 to protrude largely in advance. be able to. Therefore, the pistons 6 and 8 do not get in the way during daily use, and the convenience of the vehicle seat 1 is not sacrificed.

図５は、この発明の第２の実施形態を示す。
この実施形態の車両用シート１０１は、基本的な構成は第１の実施形態とほぼ同様であるが、リクライニングシャフト４内を流体配管１０の一部に利用し、押圧用のピストン８をリクライニングシャフト４の端部から車体幅方向外側に突出させている。 FIG. 5 shows a second embodiment of the present invention.
The basic structure of the vehicle seat 101 of this embodiment is substantially the same as that of the first embodiment, but the inside of the reclining shaft 4 is used as part of the fluid piping 10 and the pressing piston 8 is used as the reclining shaft. 4 is projected outward from the end of the vehicle body in the vehicle width direction.

この車両用シート１０１の場合、リクライニングシャフト４の端部から押圧用のピストン８を突出させるようにしているため、乗員の腰部の側方に乗員保護空間を確保することができ、また、流体配管１０の一部にリクライニングシャフト４を利用しているため、部品点数の削減を図れるというさらなる利点がある。   In the case of this vehicular seat 101, the pressing piston 8 protrudes from the end of the reclining shaft 4, so that an occupant protection space can be secured on the side of the occupant's waist, and the fluid piping Since the reclining shaft 4 is used for a part of 10, there is a further advantage that the number of parts can be reduced.

図６，図７は、この発明の第３の実施形態を示す。
この実施形態の車両用シート２０１は、やはり基本的な構成は第１の実施形態とほぼ同様であるが、リクライニングシャフト４内を流体配管１０の一部に利用し、荷重受け用のピストン６をリクライニングシャフト４の端部から車体幅方向外側に突出させ、押圧用ピストン８をバックフレーム７Ａの上部付近（着座する乗員の胸位置付近）から車体幅方向外側に突出させている。 6 and 7 show a third embodiment of the present invention.
The vehicular seat 201 of this embodiment is basically the same as that of the first embodiment, except that the inside of the reclining shaft 4 is used as a part of the fluid pipe 10 and the load receiving piston 6 is used. The pressing piston 8 protrudes from the end of the reclining shaft 4 outward in the vehicle width direction, and protrudes outward from the vicinity of the upper portion of the back frame 7A (in the vicinity of the chest position of the seated occupant).

この車両用シート２０１では、バックフレーム７Ａの上部付近から押圧用のピストン８を突出させるようにしているため、乗員の胸部の側方に乗員保護空間を確保することができる。そして、流体配管１０の一部にリクライニングシャフト４を利用しているため、部品点数の削減を図ることができるうえ、シートバック３の傾動中心と流体配管１０の一方の横配管が合致していることから、図７に示すように、シートバック３を傾動する場合にも流体配管１０（接続配管１０ｃ）が支障になることがない。   In the vehicle seat 201, the pressing piston 8 protrudes from the vicinity of the upper portion of the back frame 7A, so that an occupant protection space can be secured on the side of the occupant's chest. And since the reclining shaft 4 is utilized for a part of fluid piping 10, the number of parts can be reduced and the tilting center of the seat back 3 and one horizontal piping of the fluid piping 10 match. Therefore, as shown in FIG. 7, even when the seat back 3 is tilted, the fluid piping 10 (connection piping 10c) does not become an obstacle.

図８，図９は、この発明の第４の実施形態を示す。
この実施形態の車両用シート３０１は、基本的な構成は第１の実施形態とほぼ同様であるが、押圧用のピストン３０８の受圧面積が受圧用のピストン３０６の受圧面積よりも大きくなっている点が異なっている。 8 and 9 show a fourth embodiment of the present invention.
The vehicle seat 301 of this embodiment is basically the same as the first embodiment, but the pressure receiving area of the pressing piston 308 is larger than the pressure receiving area of the pressure receiving piston 306. The point is different.

この車両用シート３０１の場合、押圧用のピストン３０８の受圧面積が受圧用のピストン３０６の受圧面積よりも大きくことから、図９に示すように押し返すスロークは短くなるものの、入力荷重に対して大きな力でサイドドア９を押し返すことができる。したがって、乗員保護空間を確保するうえでより有利となる。   In the case of the vehicle seat 301, the pressure receiving area of the pressing piston 308 is larger than the pressure receiving area of the pressure receiving piston 306, so that the return stroke is short as shown in FIG. The side door 9 can be pushed back with force. Therefore, it is more advantageous in securing the passenger protection space.

なお、この発明は上記の実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の設計変更が可能である。   In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
