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。 This invention relates to a seatbelt that automatically unfastens the belt without manual intervention when attempting to get out of a car seat.
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, when it comes to seatbelts, the focus has been on prevention and ingenuity to prevent them from coming off easily even in the event of an accident such as a collision. Various small items are also available on the market to reduce the trouble and difficulty of installing the device. However, when getting out of the car, I forgot to fasten my seatbelt, skipped the steps to unlock the buckle, and tried to get out of the car carelessly, injuring my shoulders, neck, and ribs. The number of middle-aged and elderly people who are forced to go to the hospital is increasing, and it is attracting attention as a new daily small accident in an aging society, and although it is not a life-threatening accident, it is quite troublesome for middle-aged and elderly people and cannot be taken lightly. .
A seatbelt device is also known that aims to relieve the trouble of manually unlocking a buckle (see Patent Document 1).
There is also known an automatic release mechanism for a buckle device that can be unlocked without operating a release button (see Patent Document 2).
There is also known an automatic removable seat belt that critically examines the problems common to the above-mentioned prior art and proposes a solution from a unique angle (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 daily necessity for elderly people such as transportation, going to the hospital, shopping, etc., and the aging of drivers is unstoppable. Hidden behind the news of major accidents such as fatal sudden start accidents caused by pressing the wrong pedal, seemingly "minor" bodily injury accidents caused by "forgetting to take off the seatbelt" are steadily increasing in frequency around us on a daily basis. , which increases the subsequent development of chronic physical pain. A pioneering product in the form of preventive goods that will respond to the new phenomenon of ``car-related accidents'' in an aging society is eagerly awaited.
In the past, technological development related to automatic release of seatbelts was primarily aimed at improving operational efficiency.
The prior art shown in Patent Document 1 and Patent Document 2 has been critically examined in detail in Patent Document 3, which is filed by the same applicant as the present application, and as a result, it has been found that ``a complex circuit requiring additional difficulty and cost is required.'' By utilizing the characteristics of the solenoid in the locking itself without requiring any mechanism or switch mechanism, a seatbelt with a simple and easy-to-use tongue-to-buckle locking/releasing mechanism was provided.
In the present application, further problems of the prior art disclosed in Patent Document 3 are identified under the responsibility of the same applicant, and means for solving the problems are presented.
The main problem was that the seatbelt locking mechanism continued to generate heat while the vehicle was in motion. To deal with the danger of high heat generation and accumulation, it is possible to cover the mechanism with a highly heat-resistant material (this is possible, but would be costly), or to eliminate or minimize the heat generation and accumulation in the locked state. The question was whether to make it harmless.
This petition took up the latter as its mission and made efforts to resolve the issue.
In order to provide a more realistic path to implementation, the present invention provides a seatbelt equipped with a more effective automatic release means for locking and releasing the seatbelt using a solenoid.
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。A seat belt equipped with a buckle body that is integrally integrated with a buckle mechanism part, and a bidirectional holding type solenoid having a movable iron core, that is, a plunger, which moves in opposite directions when energized and de-energized. The buckle body will be described below when it is installed on the right side, with the solenoid part on the door side and the buckle mechanism part on the body side.
The outer L-shaped box-shaped buckle case has the buckle mechanism part on one vertical side of the L-shape and the solenoid part on the horizontal side, which are installed in an integrated manner, and both the vertical and horizontal pieces share the bottom of the case. ing.
The left end of the buckle case is slightly thicker and forms the buckle base wall, and the right end forms the solenoid part base wall. A lock having a buckle base wall, a mechanism partition facing the buckle base wall that forms the outer shell of the buckle mechanism part and partitioning the solenoid part, a closed bottom of the case, and a tongue insertion hole in the center for inserting the tongue plate. The space surrounded by the ceiling surface of the mechanism storage forms a lock mechanism storage in which a mechanism portion for locking and unlocking the tongue plate is installed.
Hereinafter, the respective structures of the solenoid section and the buckle mechanism section inside the buckle case and the relationship between the two will be explained.
In the solenoid part, surrounding the movable iron core plunger base part that passes through the center laterally, there are three sections, in order from the buckle mechanism side: a energized displacement direction part, a permanent magnet part, and a non-energized displacement direction part. The plunger base shaft part extends into the buckle mechanism part by penetrating the mechanism partition wall to the left end side, and at the left end, the plunger lock mechanism is vertically installed inside the lock mechanism storage. It is continuous and integrally formed in a shape perpendicular to the pieces.
In the plunger locking mechanism piece, the side that joins to the plunger base portion and stands up perpendicularly has a height that occupies most of the height space of the locking mechanism housing, and forms the plunger tongue reception portion, and the opposite side The side facing the buckle base wall on the side is about half the height and twice as thick as the upper part, and at the upper end surface of the thickness width, there is a tongue tip inserted from above, that is, the side that faces the buckle base wall. A lock tank is formed by recessing into a groove with a width that can accommodate the front end area of the lock hole in the tongue plate, and the edge of the lock tank facing the buckle base wall functions as a lock release piece. A lock pawl is provided in such a way that it protrudes from the buckle base wall side and slopes downward at a height position that exactly hits the lower end (front end) of the lock hole in the tongue plate when the tongue plate is locked.
In this way, in the locked state, the plunger locking mechanism piece is in close contact with the buckle base wall on the unlocked side, creating an extra space between it and the mechanism partition side, and in the unlocked state, the plunger locking mechanism piece is in close contact with the buckle base wall on the unlocked side, and in the unlocked state, the plunger locking mechanism piece An extra space is created between the base wall and the mechanism partition wall, and the structure is displaced into close contact with the mechanism partition wall. The former displacement corresponds to when energized, and the latter corresponds to when energized.In this way, the troublesome problem of continuously generating high heat while driving is solved, and the automatic lock/release function is smoothly performed. carried out.
This is a fully automatic release seat belt characterized by having the buckle body as described above.
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。At present, cars have become a daily necessity for the elderly, and in order to prevent the frequent occurrence of accidents caused by forgetting to take off their seatbelts when getting out of the car, which are ``small but can lead to serious chronic illness'', the patent document 3 is being developed. An invention idea was proposed. If implemented, it would definitely contribute to society, but as practical considerations for implementation progressed, it became clear that there was still room for improvement, which led to the filing of the present application by the same applicant. there were.
According to the present application, it is no longer necessary to improve the tongue plate in Patent Document 3, and the conventional tongue plate can be used as is.
Of course, there is no need for a complicated and unrealistic release mechanism as in Patent Document 1 or Patent Document 2. We squarely identified that the "continuously locked state while driving", which was almost the single biggest concern in Patent Document 3, is due to the structure maintained by the energization state of the solenoid, and the problem is that it is caused by the structure maintained by the energization state of the solenoid. The problem of processing high heat generation has been resolved. The electromagnetic force of the solenoid acts in one direction or the other only when the car engine switch is touched ON (lock direction) and OFF (release direction), and the permanent magnet continues to maintain the locked state during that time. , the very trigger for high fever was eliminated.
This will greatly increase the feasibility of implementation, and will definitely reduce the number of situations in which elderly people routinely forget to take off their clothes when getting off the train and end up feeling ``Ah tat!''. There is no need to worry about the ``implementation'' of the invention of Patent Document 3, ``When the tongue plate is pulled out, you accidentally touch it with your hand or something and it gets hot!''. In addition, business drivers will also be able to feel a definite increase in efficiency.
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。Hereinafter, an embodiment and method of use of the buckle body (1) used in the present invention will be described with the buckle body (1) installed on the right side of the driver's seat.
The buckle body (1) is approximately L-shaped, and has a buckle mechanism part (3) on one vertical side of the L shape and a solenoid part (4) on one horizontal side, and has an outer L-shape. It is covered with a box-shaped 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) has approximately L-shaped vertical and horizontal pieces that share a bottom surface, the left end is slightly thicker and forms the buckle base wall (5), and the right end forms the solenoid part base wall (6). , the buckle base wall (5), a mechanism partition wall (7) that faces the buckle base wall (5) and partitions the solenoid part (4) while forming the outer shell of the buckle mechanism part (3), and a closed case bottom face (8). The space surrounded by the ceiling surface (19) of the locking mechanism cabinet, which has a tongue insertion hole (20) in the center for inserting the tongue plate (p), is a space in which a mechanism part for locking and unlocking the tongue plate (p) is located. It forms a lock mechanism storage (9) to be installed.
The structures of the solenoid section (4) and buckle mechanism section (3) inside the buckle case (2) and the relationship between the two will be explained below.
In the solenoid part (4), in order from the buckle mechanism part (3) side, the movable iron core plunger base part (10) that passes through the center laterally is surrounded by a part (11) in the direction of displacement when energized, and a permanent magnet part. (13), the non-energized displacement direction part (12), and the plunger base part (10) penetrates the mechanism partition wall (7) to the left end side and connects the buckle mechanism part (3). At the left end extending inward, it is integrally and continuously connected to the plunger lock mechanism pieces (14) vertically arranged inside the lock mechanism storage (7) in a manner perpendicular to the plunger lock mechanism pieces (14).
In the plunger locking mechanism piece (14), the side that joins to the plunger base portion (10) and stands up orthogonally has a height that occupies most of the height space of the locking mechanism storage (9). The side that forms the jar tongue contact part (15) and faces the buckle base wall (5) on the opposite side is about half the height, about twice as thick as the upper part, and has a thickness that is about twice as thick as the upper part. On the upper end surface, a lock tank (16) is recessed in a groove shape with a width that can receive the tongue tip (t) inserted from above, that is, the front end area sandwiching the tongue lock hole (r) of the tongue plate (p). ), and the edge of the lock tank (16) facing the buckle base wall (5) functions as a lock release piece (17). When locked, the lock pawl (18) protrudes from the buckle base wall (5) and slopes downward at a height that just hits the lower end (front end) of the tongue lock hole (r). It is provided.
Thus, in the locked state, the plunger locking mechanism piece (14) is in close contact with the buckle base wall (5) on the unlocking piece (17) side, leaving a margin between it and the mechanism partition wall (7) side. In the unlocked state, an extra space is created between the buckle base wall (5) and the mechanism partition wall (7) is displaced. The former displacement corresponds to when energized, and the latter corresponds to when energized.In this way, the troublesome problem of continuously generating high heat while driving is solved, and the automatic lock/release function is smoothly performed. carried out.
When actually using this,
While pressing the engine switch button as usual, insert the tongue plate (p) into the tongue insertion hole (h) and push it in lightly. At this time, the plunger base portion (5) is pushed to the left by the operation of the energized displacement direction portion (11), and the plunger locking mechanism piece (14) engages the tongue plate (p) that has been inserted and lowered. It is pressed against the buckle base wall (5) side, and the tongue tip (t) enters the lock tank (16), and the tip of the lock claw (18) connects to the plunger tongue contact portion (15) and the lock claw. (18), but with the help of the slope of the lock claw (18), it can be easily lowered with one light push from above, and is inserted into the tongue lock hole (r) and locked. At the same time, the plunger base portion (10) is strongly magnetically fixed by the permanent magnet portion (13), and the tongue plate (p) cannot be removed via the plunger locking mechanism piece (14). Pass it through and hold it firmly in the locked state until the engine switch is turned OFF.
When the vehicle is stopped and the engine switch is turned off, the de-energized displacement direction section (12) is activated and is pulled back to the right, that is, toward the solenoid base wall (6) by the plunger base shaft (10). At that time, the lock release piece (17) hooks the tongue tip (t) and releases it from the lock claw (18), and at the same time, the tongue plate (p) slips out of the buckle body. All the while, it is an automatic process. Elderly drivers also do not need to intend to unfasten their seat belts. Business drivers can simply turn off the switch and get out of the car and get to work, which will definitely improve work efficiency.
