Abstract
Description
自動車の座席から降りようとする際に、手動に依らず自動的にベルトが外れるシートベルトに関する。To provide a seat belt that automatically unbuckles when a occupant tries to get out of a car seat without manual action.
従来、シートベルトに関しては、衝突等の事故における衝撃でも容易に外れないための予防・工夫に主眼が置かれた。装着の面倒さや解り辛さを軽減するための種々の小品目も販売されている。しかし、自動車から降りる時に、シートベルトを掛けていることをつい忘れ、バックルのロックを解除する動作手順をスルーして思わず無造作に降りようとして、肩や首やあばらを痛めてしまい、何度も病院通いを強いられてしまうという中高年者が増えており、高齢化社会の新しい日常的小事故、命にかかわる事故ではないが中高年者にはかなり厄介で尾を引く軽視できない事故として注目されている。
バックルのロック解除を手動による面倒から解放するべく目途したシートベルト装置も知られている（特許文献１参照）。
レリーズボタンの操作を要せずにロック解除できるようなバックル装置の自動解離機構も知られている（特許文献２参照）。
上記先行技術に共通する問題点を批判的に検討しつつ、独自の角度から解決手段を提起した自動脱着式シートベルトも知られている（特許文献３参照）。 Conventionally, the focus of seat belts has been on prevention and ingenuity to prevent seat belts from coming undone easily even in the event of an impact such as a collision. Various small items to reduce the hassle and difficulty of fastening are also sold. However, there is an increasing number of middle-aged and elderly people who forget that they are fastening their seat belts when getting out of a car, skip the procedure to unlock the buckle, and try to get out carelessly, hurting their shoulders, necks, and ribs, and forcing them to go to the hospital multiple times. These accidents are attracting attention as a new type of everyday minor accident in an aging society, not life-threatening but quite troublesome for middle-aged and elderly people, and have long-lasting effects that cannot be ignored.
There is also known a seat belt device that aims to eliminate the need for manual unlocking of the buckle (see Patent Document 1).
An automatic release mechanism for a buckle device is also known, which can release the lock without the need to operate a release button (see Patent Document 2).
There is also known an automatically detachable seat belt that critically examines the problems common to the above-mentioned prior art and proposes a solution from a unique perspective (see Patent Document 3).
本格的な高齢化社会の到来で、車が高齢者の移動、通院、買い物等の生活必需品となり、運転者の高齢化は止めようがない。ペダル踏み間違いによる致命的な急発進事故等の大事故ニュースの陰に隠れて、身の周りで日常的に着実頻繁に増加している「シートベルト外し忘れ」による一見「小さな」身体損壊事故が、その後の継続的な身体苦痛の持病化を増進させている。高齢化社会の新しい「車関連事故」の事象に対応する予防グッズの先駆け商品が待たれている。
従来、シートベルトの自動解除化に関わる技術開発は、主として業務効率化を目途したものであった。
特許文献１及び特許文献２に示される先行技術は、本願出願と出願人同一に係る特許文献３において詳細な批判的検討を加えられ、その帰結として「複雑な追加的な困難・コストを要する回路機構やスイッチ機構を要せず、ソレノイドの特性をロックそのものに利用することによって、単純明快で使い易いタング・バックル間のロック・解除機構を備えたシートベルト」が提供されていた。
本願においては、上記特許文献３に示された先行技術を、同一出願人の責任においてその更なる問題点を析出し、その解決手段が提示される。
問題点のポイントは、走行中にロックされたシートベルトのロック機構内がずっと熱を発生し続けることであった。発生蓄積した高熱の危険への対処法として、高耐熱性素材によって機構を外装するか（それは可能ではあるが高コストが見込まれる）、それともロック状態に於ける熱発生蓄積そのものをなくす・又は最小化（無害化）するか、であった。
本願は後者を任務として採り上げ、解決へ尽力した。
ここに実施化へのより現実的な道筋をつけるべく、ソレノイド利用のシートベルトロック－解除に係る一層効果的な自動解除手段を備えたシートベルトを提供するものである。 With the arrival of a full-fledged aging society, cars have become a necessity for the elderly to travel, go to the hospital, go shopping, etc., and the aging of drivers is inevitable. Hidden in the shadow of major accident news such as fatal sudden acceleration accidents caused by pedal misapplication, seemingly "minor" physical injury accidents caused by "forgetting to undo seat belts" are steadily increasing in frequency around us on a daily basis, and are promoting the chronicity of continuous physical pain that follows. Pioneer products for preventive goods that can deal with the new phenomenon of "car-related accidents" in an aging society are eagerly awaited.
Traditionally, technological development related to automatic seat belt release has been aimed primarily at improving operational efficiency.
The prior art shown in Patent Documents 1 and 2 was subjected to a detailed critical examination in Patent Document 3, which is assigned to the same applicant as the present application, and as a result, "a seat belt equipped with a simple, clear, and easy-to-use locking/unlocking mechanism between the tongue and the buckle is provided by utilizing the characteristics of a solenoid for the lock itself, without requiring any circuit mechanisms or switch mechanisms that would be complicated and require additional difficulty and cost."
In this application, the applicant hereof is responsible for identifying further problems with the prior art shown in the above-mentioned Patent Document 3, and presenting means for solving the problems.
The main problem was that the locking mechanism of the seat belt kept generating heat while the vehicle was in motion. To deal with the danger of the accumulated heat, the mechanism was either covered with a highly heat-resistant material (this was possible but would be expensive), or the heat generation and accumulation itself in the locked state was eliminated or minimized (made harmless).
The present application took up the latter task and worked hard to find a solution.
In order to provide a more practical path to implementation, the present invention provides a seat belt equipped with a more effective automatic release means for solenoid-based seat belt lock-unlock.
通電時と非通電時に相互反対方向に移動する可動鉄芯即ちプランジャーを有する双方向保持型ソレノイドを、バックル機構部と一体的に組み込んで成るバックル体を備えるシートベルトであって、運転座席の右側に設置されて、ソレノイド部がドア側に、バックル機構部が身体側にある状態において、以下バックル体を説明する。
外郭Ｌ字型ＢＯＸ状バックルケースは、その内部のＬ字縦片側にバックル機構部を、横片側にソレノイド部を、一体的に組み合わされた形で設置され、縦横両片はケース底面を共有している。
バックルケースの左端は少し分厚く形成されてバックル基壁を成し、右端はソレノイド部基壁を成す。バックル基壁と、それに対面し共にバックル機構部の外郭を成しつつソレノイド部との間を仕切る機構隔壁と、閉じられたケース底面と、中央部にタングプレートを挿し込むタング挿入孔を有するロック機構庫天井面とで囲われた空間は、タングプレートをロック－解除する機構部分が設置されるロック機構庫を形成する。
以下、バックルケース内部のソレノイド部とバックル機構部の、各々の構造と両者の連関を説明する。
ソレノイド部において、中心部を横に貫く可動鉄芯プランジャー基軸部を取り巻く形で、バックル機構部側から順に、通電時変位方向部、永久磁石部、非通電時変位方向部が、３区分状に形成され、プランジャー基軸部は、左端側へ機構隔壁を貫通して、バックル機構部の中へ延設された左端において、ロック機構庫の内部で上下に立設されているプランジャーロック機構片と直交する形で連続一体的に結合形成されている。
プランジャーロック機構片において、プランジャー基軸部に接合して直交的に立ち上がった側は、ロック機構庫の高さ空間の大半を占める高さを有してプランジャータング応接部を成し、反対側のバックル基壁に対面する側は、その半分程の高さで、厚みが上部の倍程に成っており、且つその厚み幅の上端面において、上から挿し込まれて来るタング先端部即ちタングプレートにおけるロック孔の先方端域を受け入れられる幅で、溝状に凹んでロック槽を形成してあり、ロック槽におけるバックル基壁に面する縁はロック解除片として機能する。そのロックされた時に、タングプレートにおけるロック孔の下端（先方端）に丁度当たる高さ位置において、バックル基壁側から突き出て先方へ斜降する形で、ロック爪が設けてある。
斯くして、プランジャーロック機構片は、ロックされた状態では、ロック解除片側においてバックル基壁と密接して、機構隔壁側との間に余裕の空間を生じ、ロック解除された状態では、バックル基壁との間に余裕の空間を生じて機構隔壁に密接する形に変位する。前者の変位は通電時に照応し、後者の変位は非通電時に照応し、この様にして走行中継続して高熱を発生し続けるという厄介な問題を解消し、スムーズに自動的ロック⇔解除機能が遂行される。
以上の様なバックル体を備えることを特徴とする全自動解除式シートベルトである。 This seat belt is equipped with a buckle body formed by integrally incorporating a bidirectional retaining solenoid having a movable iron core, or plunger, which moves in opposite directions when energized and de-energized, into a buckle mechanism. The buckle body will be described below in the case where the seat belt is installed on the right side of the driver's seat, with the solenoid part on the door side and the buckle mechanism part on the body side.
The L-shaped outer box-like buckle case has a buckle mechanism part on one vertical side of the L shape inside and a solenoid part on one horizontal side, which are integrally installed, and both the vertical and horizontal parts share the bottom surface of the case.
The left end of the buckle case is slightly thicker and forms the buckle base wall, and the right end forms the solenoid base wall. The space surrounded by the buckle base wall, the mechanism partition wall that faces it and forms the outer shell of the buckle mechanism while separating it from the solenoid, the closed case bottom, and the lock mechanism chamber ceiling surface that has a tongue insertion hole in the center for inserting the tongue plate forms the lock mechanism chamber where the mechanism that locks and unlocks the tongue plate is installed.
The structures of the solenoid section and the buckle mechanism section inside the buckle case and the relationship between them will be described below.
In the solenoid section, the movable iron core plunger base shaft section that passes horizontally through the center is surrounded by three sections: a section in the direction of displacement when current is applied, a permanent magnet section, and a section in the direction of displacement when current is not applied, which are arranged in that order from the buckle mechanism section side. The plunger base shaft section penetrates the mechanism partition wall to the left end side and extends into the buckle mechanism section, and at its left end, it is continuously and integrally connected to the plunger lock mechanism pieces that are erected vertically inside the lock mechanism compartment, in a manner that is perpendicular to them.
The plunger lock mechanism piece has a side that is joined to the plunger base shaft and rises perpendicularly, occupying most of the height space of the lock mechanism housing to form a plunger tongue receiving portion, and the opposite side facing the buckle base wall is about half that height and twice as thick as the upper part, and the upper end surface of that thickness is recessed in a groove shape to form a locking groove with a width that can receive the tip of the tongue inserted from above, i.e., the front end area of the locking hole in the tongue plate, and the edge of the locking groove facing the buckle base wall functions as an unlocking piece. At a height position that just hits the lower end (front end) of the locking hole in the tongue plate when locked, a locking claw is provided that protrudes from the buckle base wall side and slopes downward toward the front.
Thus, when the plunger lock mechanism piece is in a locked state, the unlocking piece side comes into close contact with the buckle base wall, creating a clearance between it and the mechanism partition wall, and when it is unlocked, it displaces to a position where it comes into close contact with the mechanism partition wall, creating a clearance between it and the buckle base wall. The former displacement corresponds to when electricity is applied, and the latter displacement corresponds to when electricity is not applied. In this way, the troublesome problem of continuous high heat generation while driving is eliminated, and the automatic lock/unlock function is smoothly performed.
The fully automatic release seat belt is characterized by comprising the above-described buckle body.
現状において、車は高齢者にとっては生活必需品化しており、降車時のシートベルト外し忘れによる「小さな、しかし深刻な持病化にも繋がる」事故の多発化を何としてもくい止めるべく、特許文献３の発明考案が提起されていた。それは実施されれば間違いなく社会貢献に資するものであったが、実施化の現実的な検討の進行のなかで、尚改良できる余地が明確化され、同一出願人によって本願提出に至ったものであった。
本願によって、特許文献３におけるタングプレート側の改良が必要無くなり、従来のタングプレートをそのまま使用できることとなった。
勿論特許文献１あるいは特許文献２の様な、複雑且つ実施化にとって非現実的な解除機構は毛頭必要ない。特許文献３における殆ど唯一最大の懸念課題であった「走行中の継続的ロック状態」が、ソレノイドの通電状態によって維持される構造に由来することを真正面から摘出し、長時間の継続的通電による高熱発生の処理問題が解決に至った。ソレノイドの電磁力は、車のエンジンスイッチのＯＮ（ロック方向）とＯＦＦ（解除方向）のタッチした時に限り、一方向又は他方向に作用し、その間のロック状態の維持は永久磁石部によって継続され、高熱の発生契機そのものを除去したのである。
これによって、実施化の実現可能性を格段にアップさせ、高齢者が日常的に降車時につい外し忘れて「ア痛ッタタッ！」となる情景を確実に減らせることができる。特許文献３の発明「実施化」で危惧された「タングプレートが抜き出された時に、たまたま手かどこかに触れて「熱っチッチ！」となる心配もない。また、業務ドライバーにとっても、確実な効率化が実感できるであろう。 In the current situation, cars have become a necessity for the elderly, and the invention disclosed in Patent Document 3 was proposed in order to prevent the increase in accidents caused by forgetting to unbuckle seat belts when getting out of a car, which are "small but can lead to serious chronic diseases." If put into practice, it would undoubtedly have contributed to society, but in the course of realistic consideration of putting it into practice, it became clear that there was still room for improvement, which led to the filing of this application by the same applicant.
According to the present application, the improvement on the tongue plate as in Patent Document 3 is no longer necessary, and the conventional tongue plate can be used as is.
Of course, there is no need for a complicated and impractical release mechanism like those in Patent Document 1 or Patent Document 2. The single biggest concern in Patent Document 3, "continuous locked state while driving," is directly identified as being caused by the structure maintained by the current flowing state of the solenoid, and the problem of high heat generation caused by continuous current flowing for a long time is solved. The electromagnetic force of the solenoid acts in one direction or the other only when the engine switch of the car is touched to ON (lock direction) or OFF (release direction), and the lock state is maintained during that time by the permanent magnet, eliminating the very cause of high heat generation.
This will significantly increase the feasibility of implementation and certainly reduce the number of cases where elderly people forget to remove the tongue plate when getting off the vehicle and say, "Ouch, ouch!" There will also be no need to worry about "when the tongue plate is pulled out, accidentally touching it with your hand or something and feeling it's hot," as was feared in the "implementation" of the invention in Patent Document 3. Commercial drivers will also be able to feel the definite efficiency improvement.
以下、本発明に使用されるバックル体（１）を、運転座席の右側に設置された状態に於いて、その実施形態と使用方法を説明する。
略Ｌ字型状のバックル体（１）であって、Ｌ字縦片側にバックル機構部（３）を、横片側にソレノイド部（４）を、一体的に組み合わせた形で、外郭Ｌ字型ＢＯＸ状バックルケース（２）で覆われており、ソレノイド部（４）がドア側に、バックル機構部が身体側にある状態で設置される。
バックルケース（２）は、略Ｌ字状の縦横両片が底面を共有し、左端は少し分厚く形成されてバックル基壁（５）を成し、右端はソレノイド部基壁（６）を成し、バックル基壁（５）と、それに対面し共にバックル機構部（３）の外郭を成しつつソレノイド部（４）との間を仕切る機構隔壁（７）と、閉じられたケース底面（８）と、中央部にタングプレート（ｐ）を挿し込むタング挿入孔（２０）を有するロック機構庫天井面（１９）とで囲われた空間は、タングプレート（ｐ）をロック－解除する機構部分が設置されるロック機構庫（９）を形成している。
以下、バックルケース（２）内部のソレノイド部（４）とバックル機構部（３）の各々の構造と両者の連関を説明する。
ソレノイド部（４）において、中心部を横に貫く可動鉄芯プランジャー基軸部（１０）を取り巻く形で、バックル機構部（３）側から順に、通電時変位方向部（１１）、永久磁石部（１３）、非通電時変位方向部（１２）の３区分状に形成され、プランジャー基軸部（１０）は、左端側へ機構隔壁（７）を貫通して、バックル機構部（３）の中へ延設された左端において、ロック機構庫（７）内部で上下に立設されているプランジャーロック機構片（１４）と直交する形で、連続一体的に結合形成されている。
プランジャーロック機構片（１４）において、プランジャー基軸部（１０）に接合して直交的に立ち上がった側は、ロック機構庫（９）の高さ空間の大半を占める高さを有してプランジャータング応接部（１５）を成し、反対側のバックル基壁（５）に対面する側は、その半分程の高さで、厚みが上部の倍程に成っており、且つその厚み幅の上端面において、上から挿し込まれて来るタング先端部（ｔ）即ちタングプレート（ｐ）におけるタングロック孔（ｒ）を挟む先方端域を受け入れられる幅で、溝状に凹んでロック槽（１６）を形成してあり、ロック槽（１６）におけるバックル基壁（５）に面する縁はロック解除片（１７）として機能する。そのロックされた時に、タングロック孔（ｒ）の下端（先方端）に丁度当たる高さ位置において、バックル基壁（５）側から突き出て先方へ斜降する形で、ロック爪（１８）が設けてある。
斯くして、プランジャーロック機構片（１４）は、ロックされた状態では、ロック解除片（１７）側においてバックル基壁（５）と密接して、機構隔壁（７）側との間に余裕の空間を生ぜしめ、ロック解除された状態では、バックル基壁（５）との間に余裕の空間を生ぜしめて、機構隔壁（７）に密接する形に変位する。前者の変位は通電時に照応し、後者の変位は非通電時に照応し、この様にして走行中継続して高熱を発生し続けるという厄介な問題が解消され、スムーズに自動的ロック⇔解除機能が遂行される。
これを実際に使用する時は、
普通の手順でエンジンスイッチボタンを押しながら、タングプレート（ｐ）をタング挿入孔（ｈ）に挿し当てつつ一押し軽くグイッと押し込む。この時プランジャー基軸部（５）が通電時変位方向部（１１）の作動によって左方へ押されて、プランジャーロク機構片（１４）が、挿入降下して来たタングプレート（ｐ）をバックル基壁（５）側へと押しつける形となって、タング先端部（ｔ）は、ロック槽（１６）に入り込み、ロック爪（１８）尖端部がプランジャータング応接部（１５）とロック爪（１８）との間で挟まれて窮屈になるが、ロック爪（１８）の斜面に介助されて上から軽く一押しで簡単に降下し、タングロック孔（ｒ）に嵌入しロックされる。同時にプランジャー基軸部（１０）は永久磁石部（１３）によって強力に磁着固定され、プランジャーロック機構片（１４）を介してタングプレート（ｐ）は外れようがない形で、車の走行中を通して、エンジンスイッチがＯＦＦになるまで、ロック状態を固く保持する。
停車して、エンジンスイッチをＯＦＦにされると同時に、非通電時変位方向部（１２）が作動し、プランジャー基軸部（１０）によって右方即ちソレノイド部基壁（６）側へ引き戻される。その時、ロック解除片（１７）がタング先端部（ｔ）を引掛けてロック爪（１８）から解放し、同時にタングプレート（ｐ）はスルスルっとバックル体から脱出していく。その間全て自動的機能のプロセスとなる。高齢運転者もシートベルトを外さねばと意図する必要もない。業務運転者もスイッチを切るだけで即降車して業務に取り掛かかることができて、作業効率は間違いなくアップすることに繋がる。 An embodiment and a method of using the buckle body (1) used in the present invention will be described below in a state where the buckle body (1) is installed on the right side of the driver's seat.
The buckle body (1) is substantially L-shaped, and is integrally assembled with a buckle mechanism part (3) on one vertical side of the L-shape and a solenoid part (4) on the other horizontal side, and is covered with an outer L-shaped box-like buckle case (2), and is installed with the solenoid part (4) on the door side and the buckle mechanism part on the body side.
The buckle case (2) is roughly L-shaped with both vertical and horizontal pieces sharing a bottom surface, with the left end being slightly thicker to form the buckle base wall (5), and the right end forming the solenoid section base wall (6). The space surrounded by the buckle base wall (5), a mechanism partition wall (7) facing it and forming the outer shell of the buckle mechanism section (3) together with the solenoid section (4) and separating it, the closed case bottom surface (8), and the lock mechanism compartment ceiling surface (19) having a tongue insertion hole (20) in the center for inserting a tongue plate (p) forms a lock mechanism compartment (9) in which a mechanism part for locking and unlocking the tongue plate (p) is installed.
The structures of the solenoid portion (4) inside the buckle case (2) and the buckle mechanism portion (3) and their relationship will be described below.
In the solenoid section (4), the movable iron-core plunger base shaft section (10) that passes horizontally through the center is surrounded and formed in three sections, which are, in order from the buckle mechanism section (3) side, a section in the direction of displacement when current is applied (11), a permanent magnet section (13), and a section in the direction of displacement when current is not applied (12). The plunger base shaft section (10) penetrates the mechanism partition wall (7) to the left end side and extends into the buckle mechanism section (3), and is continuously and integrally connected to the plunger lock mechanism pieces (14) that are erected vertically inside the lock mechanism chamber (7) at right angles to the left end.
The side of the plunger lock mechanism piece (14) that is joined to the plunger base shaft part (10) and rises perpendicularly has a height that occupies most of the height space of the lock mechanism chamber (9) and forms the plunger tongue receiving part (15), while the opposite side facing the buckle base wall (5) is about half as high and twice as thick as the upper part, and the upper end surface of the thickness width is recessed in a groove shape to form a lock groove (16) with a width that can receive the tongue tip part (t) inserted from above, i.e., the front end area that sandwiches the tongue lock hole (r) in the tongue plate (p), and the edge of the lock groove (16) that faces the buckle base wall (5) functions as an unlocking piece (17). At a height position that just hits the lower end (front end) of the tongue lock hole (r) when locked, a lock claw (18) is provided that protrudes from the buckle base wall (5) side and slopes forward.
Thus, in the locked state, the plunger lock mechanism piece (14) comes into close contact with the buckle base wall (5) on the unlocking piece (17) side, leaving a space between it and the mechanism partition wall (7), and in the unlocked state, it leaves a space between it and the buckle base wall (5) and displaces into close contact with the mechanism partition wall (7). The former displacement corresponds to when electricity is applied, and the latter displacement corresponds to when electricity is not applied. In this way, the troublesome problem of continuous high heat generation while driving is eliminated, and the automatic lock/unlock function is smoothly performed.
When you actually use this,
While pressing the engine switch button in the normal procedure, insert the tongue plate (p) into the tongue insertion hole (h) and push it in lightly. At this time, the plunger base shaft portion (5) is pushed leftward by the operation of the current-carrying displacement direction portion (11), and the plunger lock mechanism piece (14) presses the inserted and lowered tongue plate (p) toward the buckle base wall (5), so that the tongue tip portion (t) enters the locking cavity (16) and the pointed end of the locking claw (18) is pinched between the plunger tongue receiving portion (15) and the locking claw (18) in a cramped position, but with the assistance of the slope of the locking claw (18), it can be easily lowered with a light push from above and fitted into the tongue locking hole (r) to be locked. At the same time, the plunger base shaft portion (10) is strongly magnetically fixed by the permanent magnet portion (13), and the tongue plate (p) cannot come off via the plunger lock mechanism piece (14), so that the locked state is firmly maintained throughout the time the vehicle is running until the engine switch is turned off.
When the vehicle is stopped and the engine switch is turned off, the non-energized displacement direction portion (12) is activated and the plunger base shaft portion (10) is pulled back to the right, i.e., toward the solenoid portion base wall (6). At that time, the unlocking piece (17) hooks the tongue tip portion (t) and releases it from the locking claw (18), and at the same time, the tongue plate (p) smoothly escapes from the buckle body. All of this is an automatic function process. Elderly drivers do not need to think about undoing their seat belts. Commercial drivers can also get off the vehicle and get to work by simply turning off the switch, which will undoubtedly lead to improved work efficiency.
