Description

自動車用スライドシート構造並びに該構造を装備した自動車Slide sheet structure for automobile and automobile equipped with the structure
　本発明は、自動車のスライドシートの構造に関し、さらには、該構造を装備した自動車に関するものである。 The present invention relates to a structure of a slide sheet of an automobile, and further relates to an automobile equipped with the structure.
　自動車の座席シートは、運転者の体格や運転姿勢、同乗者の体格等に合わせて前後へスライド可能になっている。かかる自動車の座席シートをスライド可能にする構造は、シート底部に装備されたスライド体が、自動車床面に縦方向に延設されたスライドレールに滑動可能に搭載されて成るのが一般的であり、且つ、スライドした座席シートを所定位置で固定すべく、ロック機構を備えたものとなっている。 The car seat can be slid back and forth according to the driver's physique, driving posture, passenger's physique, etc. Such a structure that enables the seat of an automobile seat to slide is generally configured such that a slide body mounted on the bottom of the seat is slidably mounted on a slide rail that extends vertically on the automobile floor. In addition, a locking mechanism is provided to fix the slid seat seat at a predetermined position.
　ところで、自動車事故が発生した場合の問題の一つとして、運転者や同乗者が座席とコントロールパネル等との間に挟まれて身動きができない状態となることが指摘されている。例えば、前方衝突事故の場合は自動車の前方が押し潰されることとなり、結果、後方へ押し出されたコントロールパネル等の車体とスライド位置をロック・固定された座席シートとの間に運転者・同乗者が挟まれた状態となる。かかる状態となった場合、運転者・同乗者が自ら車外へ避難することができなくなるだけでなく、救助する側としても時間的・作業労力的にかなり煩雑となり、救助中に後続車の追突など二次的事故の発生にも繋がりかねない。 By the way, it is pointed out that one of the problems when a car accident occurs is that the driver and passengers are stuck between the seat and the control panel and cannot move. For example, in the case of a forward collision accident, the front of the car is crushed, and as a result, the driver / passenger is placed between the vehicle body such as the control panel pushed out backward and the seat seat in which the slide position is locked and fixed. Will be sandwiched. If this happens, the driver / passenger will not be able to evacuate outside of the vehicle himself / herself, and the rescuer will be considerably troublesome in terms of time and labor, and the rear-end collision of the following vehicle during the rescue will occur. It can also lead to secondary accidents.
　従来、自動車衝突事故における運転者や同乗者の安全確保のための手段については、シートベルトによる身体の移動を制限する手段、そして、エアバッグによる投げ出された身体を受け止める手段、の二通りの手段が採用され、現在ほとんどの自動車に標準化されている。 Conventionally, as a means for ensuring the safety of a driver or a passenger in a car collision accident, there are two kinds of means: a means for restricting the movement of the body by a seat belt and a means for catching a thrown body by an airbag. Has been adopted and is now standardized on most cars.
　しかしながら、かかるシートベルトやエアバッグは、確かに運転者や同乗者を衝突事故の衝撃から守る安全技術ではあるが、衝突により押し出される車体と座席シートとの間で身体が挟まれるのを防止するための技術ではなく、そのような重大事故の際に運転者・同乗者の身体を守ることはできないものであった。 However, such a seat belt or airbag is certainly a safety technology that protects the driver and passengers from the impact of a collision accident, but prevents the body from being pinched between the body pushed out by the collision and the seat. The technology was not intended to protect the body of the driver / passenger during such a serious accident.
　本発明者は以上のような自動車のスライドシートの現状並びに従来のシートベルト及びエアバッグによる安全技術に鑑み、衝突事故の際に運転者・同乗者がコントロールパネル等の車体と座席シートとの間に挟まれることで起こる運転者・同乗者の危険と、救助における作業困難性の問題に着目し、簡便な手段を用いてそれらの問題点を一挙に解決することができないものかという着想の下、衝突検知手段とロック解除手段と強制スライド手段とを有する「自動車用スライドシート構造」を開発し、本発明の提案に至るものである。 In view of the current state of automobile seats as described above and safety technology using conventional seat belts and airbags, the present inventor has confirmed that the driver / passenger between the vehicle body such as the control panel and the seat seat in the event of a collision. Focusing on the dangers of drivers and passengers caused by being caught in a vehicle, and the difficulty of work in rescue, the idea of whether these problems can be solved at once using simple means Then, an “automobile slide seat structure” having a collision detection means, a lock release means, and a forced slide means has been developed, which leads to the proposal of the present invention.

　上記問題点に鑑み、本発明は、衝突事故の際に運転者・同乗者が座席シートとコントロールパネル等との間に挟まれることで起こる運転者・同乗者の危険と、救助における作業困難性を解決する自動車用スライドシート構造並びに該構造を装備した自動車を提供することを目的とするものである。 In view of the above-described problems, the present invention provides a driver / passenger danger caused by a driver / passenger being sandwiched between a seat seat and a control panel in a collision accident, and difficulty in rescue operation. An object of the present invention is to provide an automobile slide seat structure that solves the above problem and an automobile equipped with the structure.
　上記目的を達成するため、本発明は、自動車床面に縦方向に延設されるスライドレールと、座席シート底部に装備され且つスライドレールに滑動可能に搭載されるスライド体と、スライドレールにおけるスライド体の滑動をロックするロック機構と、から成る自動車用スライドシートにおいて、自動車の衝突を検知する衝突検知手段を備えると共に、該衝突検知手段からの衝突情報に基づきスライドレールにおけるスライド体のロックを解除するロック解除手段を備え、かつ、該衝突検知手段からの衝突情報に基づき座席シートを衝突慣性と逆方向に所定量だけ強制的にスライドさせる強制スライド手段が備えられた自動車用スライドシート構造である。 In order to achieve the above object, the present invention provides a slide rail that extends in the longitudinal direction on a vehicle floor, a slide body that is mounted on the bottom of a seat and is slidably mounted on the slide rail, and a slide in the slide rail. An automobile slide seat comprising: a lock mechanism that locks the sliding of the body, and includes a collision detection unit that detects a collision of the vehicle, and releases the lock of the slide body on the slide rail based on the collision information from the collision detection unit And a forcible slide means for forcibly sliding a seat seat by a predetermined amount in a direction opposite to the collision inertia based on collision information from the collision detection means. .
　また、本発明は、前記衝突検知手段からの衝突情報に基づき座席シートのリクライニング角度を所定角度に直す強制リクライニング機能が備えられた構成を採用し得る。 Further, the present invention may employ a configuration provided with a forced reclining function for correcting the reclining angle of the seat seat to a predetermined angle based on the collision information from the collision detecting means.
　さらに、本発明は、前記強制スライド手段により座席シートを強制的にスライドする際のスライド量が、２０～６０ｃｍの範囲内である構成となっている。 Furthermore, in the present invention, the sliding amount when the seat is forcibly slid by the forced sliding means is in the range of 20 to 60 cm.
　またさらに、本発明は、前記自動車用スライドシート構造を装備した自動車であって、前記自動車用スライドシート構造が、自動車の運転席シート、助手席シート並びに後部席シートのうち一以上の座席シートに採用された構成となっている。 Still further, the present invention is an automobile equipped with the above-mentioned automobile slide seat structure, wherein the automobile slide seat structure is applied to one or more seat sheets among a driver seat, a passenger seat and a rear seat of the automobile. It has been adopted.

　本発明は、自動車床面に縦方向に延設されるスライドレールと、座席シート底部に装備され且つスライドレールに滑動可能に搭載されるスライド体と、スライドレールにおけるスライド体の滑動をロックするロック機構と、から成る自動車用スライドシートにおいて、自動車の衝突を検知する衝突検知手段を備えると共に、該衝突検知手段からの衝突情報に基づきスライドレールにおけるスライド体のロックを解除するロック解除手段を備え、かつ、座席シートを衝突慣性と逆方向に所定量だけ強制的にスライドさせる強制スライド手段が備えられていることを最大の特徴とする　。以下、本発明にかかる自動車用スライドシート構造並びに該構造を装備した自動車について、図面に基づき説明する。 The present invention relates to a slide rail that extends vertically on an automobile floor, a slide body that is mounted on the bottom of a seat and is slidably mounted on the slide rail, and a lock that locks the slide of the slide body on the slide rail. A slide seat for an automobile comprising a mechanism, and a collision detection means for detecting a collision of the automobile, and a lock release means for releasing the lock of the slide body on the slide rail based on the collision information from the collision detection means, In addition, the greatest feature is that a forced slide means for forcibly sliding the seat seat by a predetermined amount in the direction opposite to the collision inertia is provided. Hereinafter, a slide sheet structure for an automobile according to the present invention and an automobile equipped with the structure will be described with reference to the drawings.
　なお、本発明は、下記の実施形態に示した構成に特に限定されるものではなく、本発明の技術的思想の要旨に逸脱しない範囲で任意に変更することができるものである。例えば、本発明における自動車とは、普通乗用車のみならず、バスやトラック等、スライドシートを備えるあらゆる自動車を想定し得る。 The present invention is not particularly limited to the configurations shown in the following embodiments, and can be arbitrarily changed without departing from the spirit of the technical idea of the present invention. For example, the automobile in the present invention can be assumed not only a normal passenger car but also any automobile having a slide seat such as a bus or a truck.
　図１乃至図４は、本発明に係る自動車用スライドシート構造の実施形態を示す説明図である。
　本発明に係る自動車用スライドシート構造は、図１（ａ）に示す通り、衝突検知手段と、ロック解除手段と、強制スライド手段と、から構成されている。 1 to 4 are explanatory views showing an embodiment of a slide sheet structure for an automobile according to the present invention.
As shown in FIG. 1 (a), the automobile slide seat structure according to the present invention includes a collision detection means, a lock release means, and a forced slide means.
　本発明が採用される自動車のスライドシートの構造については、スライドレールと、スライド体と、ロック機構から成る一般的な構造のものを用いればよい。すなわち、スライドレールは、スライド体が滑動可能なレール構造を有し、自動車床面において座席シートの幅に応じて左右夫々に縦方向へ延設されて成る。またスライド体は、スライドレールに搭載して滑動可能な構造であって、座席シートの底部におけるスライドレールに対応する箇所に装備されている。さらにロック機構は、スライドレールにおけるスライド体の滑動をロックするもので、具体的構造について限定はなく、常法の構造のものを用いればよい。
　なお、電動式スライドシートや手動ロック解除式スライドシートのいずれのスライドシートであっても、本発明を採用することが可能である。 The structure of the slide sheet of the automobile in which the present invention is adopted may be a general structure composed of a slide rail, a slide body, and a lock mechanism. That is, the slide rail has a rail structure in which the slide body is slidable, and is extended in the vertical direction on the left and right according to the width of the seat on the automobile floor. The slide body has a structure that is slidable by being mounted on the slide rail, and is provided at a position corresponding to the slide rail at the bottom of the seat. Furthermore, the locking mechanism locks the sliding of the slide body on the slide rail, and there is no limitation on the specific structure, and a conventional structure may be used.
It should be noted that the present invention can be adopted regardless of whether the slide sheet is an electric slide sheet or a manual unlocking slide sheet.
　衝突検知手段は、自動車の衝突を検知するものであって、例えば自動車のフロントバンパーやリアバンパーにセンサを備え、該センサにより衝突を検知するものである。かかる衝突検知手段として、例えばエアバッグシステムに採用されている手段をそのまま採用することができ、あるいは、エアバッグの作動を検知することで衝突の検知に代替する態様も可能である。このとき、強弱二段階のエアバッグシステムを採用している自動車においては、強のエアバッグが作動した場合にのみ衝突検知を行う態様が考え得る。また該衝突検知手段として、自動車周囲の障害物等を検知するレーダーやカメラによる検知手段を用いることも可能である。衝突検知手段により検知された衝突情報は、ロック解除手段に送られることとなる。 The collision detection means detects an automobile collision, and includes, for example, a front bumper and a rear bumper of the automobile, and detects the collision by the sensor. As such a collision detection means, for example, a means employed in an airbag system can be employed as it is, or a mode in which the detection of the collision is detected by detecting the operation of the airbag is possible. At this time, in an automobile adopting a strong and weak two-stage airbag system, a mode in which collision detection is performed only when a strong airbag is activated can be considered. As the collision detection means, it is also possible to use a detection means using a radar or a camera that detects obstacles around the automobile. The collision information detected by the collision detection means is sent to the lock release means.
　ロック解除手段は、前記衝突検知手段からの衝突情報を受けて、前記ロック機構によりロックされた状態のスライド体のロックを解除するものである。ロックを解除するための方法については、ロック機構の構造によって異なることとなるが、例えば手動ロック解除式スライドシートであれば、操作レバーを強制解除する装置を備える方法が考えられ、また、電動式スライドシートであれば、スライド用の電動モータを強制除外する装置によりフリースライド状態にする方法などが考え得る。 The lock release means receives the collision information from the collision detection means and releases the lock of the slide body locked by the lock mechanism. The method for releasing the lock varies depending on the structure of the lock mechanism. For example, in the case of a manual unlocking type slide seat, a method including a device for forcibly releasing the operation lever is conceivable. If it is a slide sheet, the method of making it a free slide state by the apparatus which forcibly excludes the electric motor for a slide can be considered.
　強制スライド手段は、前記ロック解除手段によりフリースライド状態となった座席シートを強制的にスライドさせるものであって、前記衝突検知手段からの衝突情報を受けて、衝突慣性と逆方向に強制的にスライドさせるものである。すなわち、前方衝突の場合は、前方向へ慣性力が働くため、座席シートは後方へ強制的にスライドさせることとなり、逆に後方衝突の場合は後方向へ慣性力が働くため、座席シートは前方へ強制スライドさせることとなる。前方衝突か後方衝突かは、前記衝突検知手段からの衝突情報により瞬時に判断される。なお、レーダーやカメラ等の周囲の障害物を検知できる手段を衝突検知手段として採用した場合に、該レーダー等で迫りくる危険を早めに検知して、実際の衝突前に座席シートを強制的にスライドさせる態様も可能であり、これにより衝突前に衝突への態勢を整えることが可能となる。 The compulsory slide means forcibly slides the seat seat that has been brought into a free slide state by the unlocking means, and receives the collision information from the collision detection means and forcibly reverses the collision inertia. It is to be slid. That is, in the case of a frontal collision, the inertial force works in the forward direction, so the seat is forced to slide backwards. Will be forced to slide. Whether it is a forward collision or a backward collision is determined instantaneously based on collision information from the collision detection means. When a means that can detect surrounding obstacles such as a radar or camera is adopted as a collision detection means, the danger of approaching with the radar is detected early, and the seat is forcibly forced before the actual collision. A sliding mode is also possible, which makes it possible to prepare for the collision before the collision.
　強制スライド手段における座席シートを強制的にスライドさせるための方法については、特に限定はないが、例えば強力なコイルばねの押力若しくは引張力を利用して、座席シートを該ばね力によりスライドさせる方法や、あるいは、所定箇所にエアシリンダを装備して、エア圧により座席シートを押してスライドさせる方法などが考え得る。なお、かかる強制スライド手段は、車内居住空間に表出しないよう、座席シートの下方スペースに収まる状態で備えられる。 The method for forcibly sliding the seat in the forcible sliding means is not particularly limited. For example, a method of sliding the seat by the spring force by using a pressing force or tensile force of a strong coil spring. Alternatively, a method of mounting an air cylinder at a predetermined location and pushing and sliding the seat by air pressure can be considered. In addition, this forced slide means is provided in a state that fits in the space below the seat so as not to be exposed in the in-car living space.
　ところで、前記強制スライド手段により座席シートを強制的にスライドするに際し、どこまでもスライドさせればよいというものではなく、後部席シートにおいて前席シートとの関係が問題となる。すなわち、前方衝突において前席シートが後方へ強制的にスライドさせられた場合に、その後部席シートとの間で該後部席シートの同乗者が身体（特に脚）を挟まれる危険が生じることとなる。よって、座席シートのスライド量については、予め定められた量だけに抑えることが必要となる。そこで、本発明では、２０～６０ｃｍの範囲内で座席シートを強制的にスライドする態様が望ましく、具体的スライド量については前席シートと後部席シートとの間隔によって決定される。かかる態様を採用することにより、後部席シートの同乗者の身体の安全スペースが確保されることとなる。 By the way, when the seat is forcibly slid by the forcible sliding means, it does not have to be slid anywhere, and the relationship between the rear seat and the front seat becomes a problem. That is, when the front seat is forcibly slid rearward in a frontal collision, there is a risk that a passenger (especially a leg) of the rear seat is caught between the rear seat and the rear seat. Become. Therefore, it is necessary to suppress the seat seat slide amount to a predetermined amount. Therefore, in the present invention, a mode in which the seat is forcibly slid within a range of 20 to 60 cm is desirable, and the specific slide amount is determined by the interval between the front seat and the rear seat. By adopting such a mode, a safety space for the passenger's body of the rear seat is secured.
　前記強制スライド手段が備えられる座席シートは、少なくとも運転席シートに備えられるほか、助手席シート並びに後部席シートに備える態様が可能である。このとき、後部席シートに強制スライド手段を備えて強制スライド可能とすることで、運転席シート及び助手席シートのスライド量を増加させることが可能となる。なお、後部席シートがベンチシート形態の場合に、該シートを幅方向所定箇所で分割し、分割された後部席シート夫々に強制スライド手段を備える態様が可能である。 The seat provided with the forced sliding means may be provided in at least a driver seat, a passenger seat and a rear seat. At this time, it is possible to increase the sliding amount of the driver seat and the passenger seat by providing the rear seat with a forced slide means to enable the forced slide. In the case where the rear seat is in the form of a bench seat, it is possible to divide the seat at a predetermined position in the width direction and to provide a forced slide means for each of the divided rear seats.
　ところで、後部座シートにおける同乗者の有無を検知する後部席同乗者検知手段を備える態様が考え得る。該後部席同乗者検知手段の具体的構成態様については、同乗者の有無を検知可能であれば特に限定はないが、例えば後部席シート上の重量を検知する方法が採用される。かかる後部席同乗者検知手段により後部席の同乗者の有無を検知することで、前席シート（運転席シート・助手席シート）のスライド量を変更させたり、あるいは、後部席シートの強制スライドを実行するか否かを決定させる、といった動作態様を採り得ることとなる。 By the way, the aspect provided with the backseat passenger detection means which detects the presence or absence of the passenger in a backseat seat can be considered. The specific configuration of the rear seat passenger detection means is not particularly limited as long as the presence or absence of a passenger can be detected. For example, a method of detecting the weight on the rear seat is employed. By detecting the presence / absence of a passenger in the rear seat by such rear seat passenger detection means, the sliding amount of the front seat (driver seat / passenger seat) can be changed, or the rear seat can be forced to slide It is possible to adopt an operation mode in which it is determined whether or not to execute.
　かかる強制スライド手段による座席シートの強制スライドに関し、スライドさせるタイミングについては、運転者・同乗者の安全性を考慮して適宜決定可能である。例えば、前記衝突検知手段からの衝突情報を受けて、エアバッグが作動すると同時に座席シートを強制的にスライドさせる態様が可能である。あるいは、衝突による運転者・同乗者の衝撃をシートベルト・エアバッグによって一旦受け止めた後に、コンマ数秒程度のタイムラグを空けて座席シートを強制的にスライドさせる態様も考え得る。 Regarding the forced sliding of the seat by such forced sliding means, the sliding timing can be determined as appropriate in consideration of the safety of the driver / passenger. For example, a mode in which the seat is forcibly slid at the same time as the airbag is activated upon receipt of collision information from the collision detection means is possible. Alternatively, a mode in which the seat seat is forcibly slid with a time lag of about several seconds after the impact of the driver / passenger due to the collision is once received by the seat belt / airbag.
　上記の通り、後部席シートの同乗者が運転席シート・助手席シートと後部席シートとの間で身体が挟まれる危険を回避する方法としては、図１（ｂ）の通り、座席シートのリクライニング角度を所定角度、好ましくは略垂直に直すための強制リクライニング機能を備える態様が考え得る。すなわち、前席シートのリクライニングが略垂直状態となることで、後部席シートの同乗者の身体の安全スペースが確保されることとなる。
　なお、前記強制リクライニング機能は、前記衝突検知手段からの衝突情報を受けて、座席シートのリクライニング角度を所定角度へ強制的に直すものであり、前方衝突であると後方衝突であるとを問わず、衝突を検知した際は常に予め定められた角度へ直すこととなる。 As described above, as a method of avoiding the danger that the passenger in the rear seat is caught between the driver seat / passenger seat and the rear seat, reclining the seat seat as shown in FIG. An aspect having a forced reclining function for correcting the angle to a predetermined angle, preferably substantially vertical, is conceivable. That is, since the reclining of the front seat is in a substantially vertical state, a safety space for the passenger of the rear seat is secured.
The forced reclining function receives the collision information from the collision detection means and forcibly corrects the reclining angle of the seat seat to a predetermined angle, regardless of whether it is a forward collision or a rear collision. When a collision is detected, the angle is always corrected to a predetermined angle.
　以上の通り構成された本発明に係る自動車用スライドシート構造について、衝突状況に合わせた一連の動作及び作用効果を説明する。
（前方衝突の場合）
　図４（ａ）に示すように、自動車が前方衝突事故を起こした場合、衝突検知手段により検知された衝突情報が、ロック解除手段及び強制スライド手段に送られる。かかる衝突情報を受け、ロック解除手段はスライドレールにおけるスライド体のロックを解除すると共に、強制スライド手段は座席シートを後方へ強制的にスライドさせる。
　以上の一連の動作により、座席シート自体が後方へ移動することで、コントロールパネル等前方車体と座席シートとの間に安全スペースが確保され、身体が挟まれて身動きが取れない状況となるのを防止することでき、迅速な避難と救助に資することとなる。 A series of operation | movement and effect which matched the collision condition are demonstrated about the slide seat structure for motor vehicles based on this invention comprised as mentioned above.
(For forward collision)
As shown in FIG. 4A, when the automobile has a forward collision accident, the collision information detected by the collision detection unit is sent to the lock release unit and the forced slide unit. In response to the collision information, the lock release means releases the lock of the slide body on the slide rail, and the forced slide means forcibly slides the seat.
With the above series of operations, the seat seat itself moves backward, so that a safety space is secured between the front vehicle body, such as the control panel, and the seat seat, and the body is sandwiched and cannot move. This will help prevent evacuation and rescue.
（後方衝突の場合）
　図４（ｂ）に示すように、自動車が後方衝突事故を起こした場合、衝突検知手段により検知された衝突情報が、ロック解除手段及び強制スライド手段に送られる。かかる衝突情報を受け、ロック解除手段はスライドレールにおけるスライド体のロックを解除すると共に、強制スライド手段は座席シートを前方へ強制的にスライドさせる。
　以上の一連の動作により、運転者及び同乗者の身体が前方へ瞬時に移動するため、後方の衝突物から身体を逃がすことができ、重大事故を回避して迅速な避難と救助に資することとなる。 (In case of rear collision)
As shown in FIG. 4B, when the automobile has a rear collision accident, the collision information detected by the collision detection unit is sent to the lock release unit and the forced slide unit. In response to the collision information, the lock release means releases the lock of the slide body on the slide rail, and the forced slide means forcibly slides the seat.
By the above series of operations, the driver and passenger's bodies move forward in an instant, so the body can escape from the rear collision object, contributing to quick evacuation and rescue by avoiding a serious accident. Become.
（前方及び後方衝突の場合）
　図４（ｃ）に示すように、自動車が前方及び後方からの衝突（いわゆるサンドイッチ衝突）事故を起こした場合、衝突検知手段により検知された衝突情報が、ロック解除手段及び強制スライド手段に送られる。かかる衝突情報を受け、ロック解除手段はスライドレールにおけるスライド体のロックを解除すると共に、強制スライド手段は運転席シート及び助手席シートの前席シートを後方へ強制的にスライドさせると共に、後部席シートを前方へ強制的にスライドさせることとなる。
　以上の一連の動作により、前席シートの運転者及び同乗者の身体が後方へ瞬時に移動すると共に、後部席シートの同乗者の身体は前方へ瞬時に移動して、車内中央に寄せ集まることとなるため、前席シートの運転者及び同乗者にとっては、座席シート自体が後方へ移動することで、コントロールパネル等前方車体と座席シートとの間に安全スペースが確保され、身体が挟まれて身動きが取れない状況となるのを防止することでき、迅速な避難と救助に資することとなる。また、後部席シートの同乗者にとっては、座席シート自体が前方へ移動することで、後方の衝突物から身体を逃がすことができ、重大事故を回避して迅速な避難と救助に資することとなる。 (For front and rear collisions)
As shown in FIG. 4 (c), when the automobile has a collision from the front and rear (so-called sandwich collision), collision information detected by the collision detection means is sent to the lock release means and the forced slide means. . Upon receiving such collision information, the unlocking means unlocks the slide body on the slide rail, and the forcible sliding means forcibly slides the front seats of the driver seat and the passenger seat backward, and the rear seat. Will be forced to slide forward.
Through the above series of operations, the driver's body and the passenger's body in the front seat move instantly backward, and the passenger's body in the rear seat instantly moves forward and gather in the center of the vehicle. Therefore, for the driver and passenger of the front seat, the safety seat is secured between the front vehicle body such as the control panel and the seat seat, and the body is sandwiched by moving the seat seat backward. This prevents the situation from becoming incapable of movement and contributes to quick evacuation and rescue. In addition, for passengers in the rear seats, the seats themselves can move forward, allowing the body to escape from the rear collision object, which will contribute to quick evacuation and rescue by avoiding serious accidents. .
　次に、本発明に係る自動車用スライドシート構造を装備した自動車の実施形態について説明する。
　本発明に係る自動車は、前記自動車用スライドシート構造を装備した自動車であって、少なくとも運転席シートにおいて採用されている。なお、運転席シートのほか、図４に示すように、助手席シート並びに後部席シートにも前記自動車用スライドシート構造を装備させることが可能である。 Next, an embodiment of an automobile equipped with a slide sheet structure for an automobile according to the present invention will be described.
The automobile according to the present invention is an automobile equipped with the above-described automobile slide seat structure, and is employed at least in a driver seat. In addition to the driver's seat, as shown in FIG. 4, the passenger seat and the rear seat can be equipped with the above-described slide seat structure for automobiles.
　ところで、本発明に係る自動車において、図３に示すように、座席シートにおける座部の前部が、後方へ埋没可能なクッション材により成形する態様が望ましい。すなわち、前方衝突において前席シートの運転者・同乗者は、前方車体が押し出されて座席シートとの間に挟まれる危険があるが、前席シートにおける座部の前部について埋没可能とすることにより、前席シートの運転者・同乗者の身体が当該埋没箇所に収まることを可能とし、もって運転者・同乗者の安全が確保されることとなる。また、同じ前方衝突において前席シートが後方へ強制的にスライドさせられた場合に、後部席シートの同乗者が前席シートとの間で身体を挟まれる危険が生じることとなるが、後部席シートにおける座部の前部について埋没可能とすることにより、後部席シートの同乗者の身体が当該埋没箇所に収まることを可能とし、もって同乗者の安全が確保されることとなる。なお、クッション材の構造・材質については、通常時に後部席シートに座った状態で埋没することなく、事故時に押圧されることで埋没することとなるような構造・材質のものを選択することが望ましい。このとき、クッション材による埋没量については、最大で２０ｃｍ程度とする。 By the way, in the automobile according to the present invention, as shown in FIG. 3, it is desirable that the front part of the seat part of the seat is formed by a cushion material that can be buried backward. That is, the driver / passenger of the front seat in a frontal collision may be caught between the front seat and the front seat, but the front seat may be buried in the front seat. Thus, the driver / passenger's body of the front seat can be accommodated in the buried portion, and thus the safety of the driver / passenger is ensured. In addition, when the front seat is forcibly slid rearward in the same frontal collision, there is a risk that the passenger in the rear seat will get caught between the front seat and the rear seat. By making it possible to bury the front portion of the seat portion in the seat, the passenger's body of the rear seat can be accommodated in the buried portion, thereby ensuring the safety of the passenger. As for the structure and material of the cushion material, it is possible to select a structure and material that will be buried by being pressed at the time of an accident without being buried in the state of sitting in the rear seat at normal times. desirable. At this time, the amount of burying by the cushion material is about 20 cm at the maximum.
　以上の通り構成された本発明に係る自動車用スライドシート構造を装備した自動車によれば、前方衝突や後方衝突、そしてサンドイッチ衝突の事故が起こった場合に、運転手及び同乗者の安全・負担軽減が確保され、人身への重大事故を回避・軽減することが可能であると共に、迅速な避難と救助に資することとなる。 According to the automobile equipped with the slide sheet structure for an automobile according to the present invention configured as described above, the safety and burden on the driver and passengers can be reduced in the event of a front collision, rear collision, or sandwich collision accident. It is possible to avoid and mitigate serious accidents on the human body and contribute to prompt evacuation and rescue.
　事故時の安全装置として、第一にシートベルト、第二にエアバッグがあり、本発明は第三の安全装置として位置づけられるものである。すなわち、本発明に係る自動車用スライドシート構造並びに該構造を装備した自動車は、衝突事故時に座席シートを衝突慣性と逆方向に強制的にスライドさせることで、座席シートとコントロールパネル等との間に運転者・同乗者が挟まれるのを防止すると共に、迅速な避難と救助に資するものであって、本発明の産業上の利用可能性は大であると思料する。 As safety devices at the time of an accident, there are firstly a seat belt and secondly an airbag, and the present invention is positioned as a third safety device. In other words, the automobile slide seat structure according to the present invention and the automobile equipped with the structure are provided between the seat seat and the control panel by forcibly sliding the seat seat in a direction opposite to the collision inertia at the time of a collision accident. It prevents the driver / passenger from being caught and contributes to quick evacuation and rescue, and the industrial applicability of the present invention is considered to be great.
