It is about cars .

従来、病気や障害等によって歩行が不自由な人の使用する車椅子としては、使用者または補助者の人力によって走行するものや、使用者の運転操作によって自走可能な電動式のものなどが知られているが、車椅子の使用者が長距離を移動する場合は、使用者が着座したまま車椅子を搭載可能な車椅子搬送車が利用されている（例えば、特許文献１参照。）。
特開２００４−１１３３３６号公報 Conventionally, wheelchairs used by people who are unable to walk due to illness or disability, such as those that run by the user's or assistant's human power, or those that are self-propelled by the user's driving operation, etc. However, when a user of a wheelchair moves a long distance, a wheelchair transport vehicle that can mount the wheelchair while the user is seated is used (for example, see Patent Document 1).
JP 2004-113336 A

ところで、前記車椅子搬送車には、一般の乗用車と同様、運転席や助手席用のエアバッグを備えているが、車椅子の搭載部分にはエアバッグ等の保護装置は設けられていない。このため、車椅子搬送車が衝突事故等に遭った場合、運転席や助手席の搭乗者への衝撃は車両用のエアバッグによって吸収されるが、車椅子の使用者への衝撃は吸収することができず、車内の車椅子使用者に対する保護が万全でないという問題があった。   By the way, although the wheelchair transport vehicle includes an airbag for a driver's seat and a passenger seat, as in a general passenger car, a protection device such as an airbag is not provided in a mounted portion of the wheelchair. For this reason, when a wheelchair transporter encounters a collision accident, the impact on the driver's seat and passenger's seat is absorbed by the vehicle airbag, but the impact on the wheelchair user can be absorbed. There was a problem that the protection for wheelchair users in the car was not perfect.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、車椅子を搭載した車両が衝突事故等に遭った場合でも、車内の車椅子使用者への衝撃を効果的に吸収することのできる車椅子用エアバッグ装置及びこれを備えた車椅子搬送車を提供することにある。 The present invention has been made in view of the above-described problems, and the object of the present invention is to effectively absorb an impact on a wheelchair user in a vehicle even when a vehicle equipped with a wheelchair encounters a collision accident or the like. An object of the present invention is to provide a wheelchair airbag device and a wheelchair transport vehicle equipped with the same .

本発明は前記目的を達成するために、車椅子に着座した使用者の所定部位を覆うように膨張可能なエアバッグと、エアバッグを膨張させる膨張手段とを備え、車椅子搬送車に搭載される車椅子に用いられる車椅子用エアバッグ装置において、前記車椅子搬送車に備わるエアバッグ作動用センサから出力されるエアバッグ作動信号によって前記膨張手段を作動させる制御手段と、エアバッグ作動用センサに接続された接続ユニットと、接続ユニット側と車椅子のエアバッグ側とを接続するケーブルとを備え、接続ユニットに、複数の車椅子のエアバッグ側にそれぞれ着脱自在に接続される複数のケーブルをそれぞれ接続可能な複数のコネクタを設けている。 In order to achieve the above object, the present invention includes an airbag that can be inflated so as to cover a predetermined part of a user seated in the wheelchair, and an inflating means that inflates the airbag, and is mounted on a wheelchair carrier vehicle. In the wheelchair airbag device used for the wheelchair, the control means for actuating the inflating means by the airbag actuation signal output from the airbag actuation sensor provided in the wheelchair transport vehicle, and the connection connected to the airbag actuation sensor A plurality of cables that are detachably connected to the airbag unit side of the plurality of wheelchairs, respectively, and a cable that connects the unit and the connection unit side to the airbag side of the wheelchair . A connector is provided .

これにより、車椅子を搭載した車両が走行中に衝突事故に遭った場合など、エアバッグ作動用センサからエアバッグ作動信号が出力されると、エアバッグが膨張し、車内の車椅子の使用者への衝撃がエアバッグによって吸収される。   As a result, when an airbag activation signal is output from the airbag activation sensor, such as when a vehicle equipped with a wheelchair encounters a collision accident while traveling, the airbag is inflated, and the wheelchair user in the vehicle is informed. The impact is absorbed by the airbag.

本発明によれば、車椅子を搭載した車両が衝突事故等に遭った場合でも、車椅子の使用者への衝撃をエアバッグによって吸収することができるので、車両で移動する場合でも、車椅子の使用者を衝突時の衝撃から保護することができる。また、複数台の車椅子を車両に搭載する場合でも、車椅子ごとにエアバッグ作動用センサを設ける必要がないので、低コスト化を図ることができるとともに、複数台の車椅子に対して共通のセンサからエアバッグ作動信号を出力することができるので、各車椅子のエアバッグを常に同時に作動させることが可能である。   According to the present invention, even when a vehicle equipped with a wheelchair encounters a collision accident or the like, the impact on the wheelchair user can be absorbed by the airbag. Can be protected from impact at the time of collision. Further, even when a plurality of wheelchairs are mounted on a vehicle, it is not necessary to provide a sensor for operating the airbag for each wheelchair, so that the cost can be reduced and a common sensor can be used for the plurality of wheelchairs. Since the airbag activation signal can be output, it is possible to always activate the airbags of each wheelchair simultaneously.

Moreover, the airbag 21 on the wheelchair 1 side is also inflated by the airbag activation signal of the sensor 9b, and the impact on the user A of the wheelchair 1 in the vehicle is absorbed by the airbag 21 on the wheelchair 1 side. That is, when the airbag operation signal output from the sensor 9b is input to the control unit 25 in the connection unit 23 via the cable 23c, the control unit 25 energizes the charging device 22 via the cable 24. Thereby, the gas cylinder of the charging device 22 is opened, and the airbag 21 is inflated by the gas discharged from the gas cylinder.

このように、本実施形態によれば、車椅子１に使用者Ａの所定部位を覆うエアバッグ２１を設け、車椅子１が搭載された車椅子搬送車９のセンサ９ｂからエアバッグ作動信号が出力されると、車椅子１のエアバッグ２１を膨張させるようにしたので、車椅子搬送車９が衝突事故等に遭った場合でも、車椅子１の使用者Ａへの衝撃を車椅子１のエアバッグ２１によって吸収することができ、車椅子１の使用者Ａを衝突時の衝撃から保護することができる。この場合、車椅子１側にエアバッグ作動用センサを設ける必要がないので、低コスト化を図ることができるとともに、複数台の車椅子１に対して共通のセンサ９ｂからエアバッグ作動信号を出力することができるので、各車椅子１のエアバッグ２１を常に同時に作動させることが可能である。   Thus, according to this embodiment, the airbag 21 which covers the predetermined site | part of the user A is provided in the wheelchair 1, and an airbag operation signal is output from the sensor 9b of the wheelchair conveyance vehicle 9 in which the wheelchair 1 was mounted. Since the airbag 21 of the wheelchair 1 is inflated, the impact on the user A of the wheelchair 1 is absorbed by the airbag 21 of the wheelchair 1 even when the wheelchair transport vehicle 9 encounters a collision accident or the like. It is possible to protect the user A of the wheelchair 1 from the impact at the time of collision. In this case, since it is not necessary to provide an airbag activation sensor on the wheelchair 1 side, the cost can be reduced and an airbag activation signal is output from a common sensor 9b to a plurality of wheelchairs 1. Therefore, the airbag 21 of each wheelchair 1 can always be operated simultaneously.

また、車椅子搬送車９内に取付けた接続ユニット２３を車椅子搬送車９のセンサ９ｂに接続するとともに、車椅子１のエアバッグ２１側と接続ユニット２４とを着脱自在なケーブル２４を介して接続することにより、センサ９ｂのエアバッグ作動信号によって車椅子１のエアバッグ２１を膨張させるようにしたので、車椅子１を車椅子搬送車９に搭載する際、ケーブル２４を接続するだけの簡単な作業によって車椅子１のエアバッグ２１を作動可能な状態にすることができ、車椅子搬送車９の乗降時における作業性を向上させることができる。   In addition, the connection unit 23 attached in the wheelchair transport vehicle 9 is connected to the sensor 9b of the wheelchair transport vehicle 9, and the airbag 21 side of the wheelchair 1 and the connection unit 24 are connected via a detachable cable 24. Thus, since the airbag 21 of the wheelchair 1 is inflated by the airbag activation signal of the sensor 9b, when the wheelchair 1 is mounted on the wheelchair carrier 9, the wheelchair 1 can be easily connected by simply connecting the cable 24. The airbag 21 can be brought into an operable state, and workability when the wheelchair transport vehicle 9 gets on and off can be improved.

更に、車椅子１のエアバッグ２１を作動させる制御部２５及び充気装置２２用の電源２３ｄを接続ユニット２３側に配置し、接続ユニット２３からケーブル２４を介してエアバッグ２１の充気装置２２に通電するようにしたので、車椅子１ごとに制御部２５及び電源２３ｄを設ける必要がなく、車椅子１側の部品点数を少なくすることができる。   Further, a control unit 25 for operating the airbag 21 of the wheelchair 1 and a power supply 23d for the charging device 22 are arranged on the connection unit 23 side, and the charging device 22 of the airbag 21 is connected from the connection unit 23 via the cable 24. Since power is supplied, it is not necessary to provide the control unit 25 and the power source 23d for each wheelchair 1, and the number of parts on the wheelchair 1 side can be reduced.

この場合、エアバッグ作動用センサとして、車椅子搬送車９に備わる車両用エアバッグ９ａのセンサ９ｂを用いるようにしたので、車椅子１のエアバッグ２１用として専用のセンサを設ける必要がなく、車椅子１側の構造の簡素化及び低コスト化に極めて有利である。   In this case, since the sensor 9b of the vehicle airbag 9a provided in the wheelchair transport vehicle 9 is used as the airbag operation sensor, there is no need to provide a dedicated sensor for the airbag 21 of the wheelchair 1. This is extremely advantageous for the simplification and cost reduction of the side structure.

また、本実施形態では、車椅子１に着座する使用者Ａの前方左右両側まで延びる左右一対の身体保持部材１１によって使用者Ａの前方への移動を規制するようにしたので、急な減速等によって車椅子１の使用者Ａに前方への加速度が加わった場合、エアバッグ２１の作動時のみならず、エアバッグ２１の作動時以外でも、使用者Ａを車椅子１に確実に保持することができる。その際、車椅子１の使用者Ａを各身体保持部材１１によって前方左右両側で保持することができるので、使用者Ａが車椅子１から脱落したり、或いは局部的な圧迫を受けることもなく、使用者Ａの保護に極めて有利である。   Further, in the present embodiment, the forward movement of the user A is restricted by the pair of left and right body holding members 11 extending to the front left and right sides of the user A seated in the wheelchair 1, and therefore, by sudden deceleration or the like When forward acceleration is applied to the user A of the wheelchair 1, the user A can be reliably held in the wheelchair 1 not only when the airbag 21 is activated but also when the airbag 21 is activated. At that time, since the user A of the wheelchair 1 can be held on both the front left and right sides by the body holding members 11, the user A can be used without falling off the wheelchair 1 or receiving local pressure. It is extremely advantageous for the protection of the person A.

また、各身体保持部材１１をそれぞれ車椅子１の外側に向かって左右方向に移動可能に設けたので、各身体保持部材１１を車椅子１の外側に移動させることにより、各身体保持部材１１によって使用者Ａの乗り降りが妨げられることがなく、体の不自由な使用者Ａであっても車椅子１への乗り降りを極めて容易に行うことができる。   Further, since each body holding member 11 is provided so as to be movable in the left-right direction toward the outside of the wheelchair 1, the user can move the body holding member 11 to the outside of the wheelchair 1, thereby allowing the user to move the body holding member 11. Getting on and off of the wheelchair 1 can be performed very easily even if the user A is handicapped.

更に、各身体保持部材１１を使用者Ａの肩部上方から胸部前方に亘って延びるように形成したので、使用者Ａの上方及び前方の何れの方向への移動も規制することができ、使用者Ａをより確実に保持することができる。   Furthermore, since each body holding member 11 is formed so as to extend from the upper part of the shoulder of the user A to the front of the chest, the movement of the user A in either the upper direction or the front direction can be restricted. The person A can be held more reliably.

また、各身体保持部材１１を前端側が左右方向に開閉するように後端側を車椅子１側に回動自在に支持するようにしたので、各身体保持部材１１の前端側を左右方向に開けば車椅子１への乗り降りが可能となる。従って、各身体保持部材１１を車椅子１への乗り降りに必要な最小限の範囲で動作させることができ、例えば車椅子搬送車の車内など、狭い場所での乗り降りに好都合である。   In addition, since each body holding member 11 is rotatably supported on the wheelchair 1 side so that the front end side opens and closes in the left-right direction, the front end side of each body holding member 11 can be opened in the left-right direction. Getting on and off the wheelchair 1 is possible. Therefore, each body holding member 11 can be operated within a minimum range necessary for getting on and off the wheelchair 1, and is convenient for getting on and off in a narrow place such as in a wheelchair transport vehicle.

更に、各身体保持部材１１を付勢部材１２によって車椅子１の外側及び内側にそれぞれ付勢するようにしたので、各身体保持部材１１を前端側が開いた状態及び前端側が閉じた状態でそれぞれ保持することができる。従って、各身体保持部材１１を開いた状態での乗り降りを円滑に行うことができるとともに、各身体保持部材１１が閉じた状態から不用意に開くことがないという利点がある。   Further, since each body holding member 11 is urged to the outside and inside of the wheelchair 1 by the urging member 12, each body holding member 11 is held with the front end side opened and the front end side closed, respectively. be able to. Therefore, it is possible to smoothly get on and off in the state where each body holding member 11 is opened, and there is an advantage that each body holding member 11 does not open carelessly from the closed state.

この場合、付勢部材１２を、各身体保持部材１１の一端側に両端を固定された弾性部材によって形成し、各身体保持部材１１が所定の回動位置よりも外側に回動すると付勢部材１２の復元力によって各身体保持部材１１を外側に付勢し、各身体保持部材１１が所定の回動位置よりも内側に回動すると付勢部材１２の復元力によって各身体保持部材１１を内側に付勢するようにしたので、各身体保持部材１１を一つの付勢部材１２によって車椅子１の外側及び内側の何れの方向にも付勢することができ、構造の簡素化を図ることができる。   In this case, the urging member 12 is formed by an elastic member whose both ends are fixed to one end side of each body holding member 11, and when each body holding member 11 rotates outward from a predetermined rotation position, the urging member Each body holding member 11 is urged outward by the restoring force of 12, and each body holding member 11 is moved inward by the restoring force of the urging member 12 when each body holding member 11 rotates inward from a predetermined rotation position. Since each body holding member 11 can be urged in either direction outside or inside the wheelchair 1 by one urging member 12, the structure can be simplified. .

また、付勢部材を車椅子１の背もたれ部３の内部または後方に配置し、車椅子１に着座する使用者Ａの背中によって押圧されると後方に撓むようにしたので、車椅子１に着座した使用者Ａが背もたれ部３に寄りかかると、付勢部材１２によって各身体保持部材１１を車椅子１の内側に向かって自動で回動させることができる。従って、各身体保持部材１１の回動操作を手動で行う必要がなく、各身体保持部材１１の操作における使用者Ａの負担を大幅に軽減することができる。   Moreover, since the urging member is disposed inside or behind the backrest portion 3 of the wheelchair 1 and is bent by the back of the user A seated on the wheelchair 1, the user A seated on the wheelchair 1 is bent. When leaning on the backrest 3, each body holding member 11 can be automatically rotated toward the inside of the wheelchair 1 by the urging member 12. Therefore, it is not necessary to manually perform the rotation operation of each body holding member 11, and the burden on the user A in the operation of each body holding member 11 can be greatly reduced.

更に、各身体保持部材１１の前端側を連結部材１３によって連結可能に構成したので、各身体保持部材１１を前端側が閉じた状態で連結することができ、各身体保持部材１１の使用中の不用意な回動を確実に防止することができる。   Furthermore, since the front end side of each body holding member 11 is configured to be connectable by the connecting member 13, each body holding member 11 can be connected in a state where the front end side is closed. Prepared rotation can be reliably prevented.

この場合、連結部材１３を使用者Ａの胸部または腹部の前方に位置するように設けたので、使用者Ａの前方への移動を連結部材１３によっても規制することができ、使用者Ａをより確実に保持することができる。   In this case, since the connecting member 13 is provided so as to be positioned in front of the chest or abdomen of the user A, the forward movement of the user A can also be restricted by the connecting member 13, and the user A can be further controlled. It can be held securely.

また、連結部材１３を上下方向に所定の幅を有する帯状の部材によって形成したので、連結部材１３から使用者Ａに加わる圧力を連結部材１３の幅方向に分散させることができ、連結部材１３による局部的な圧迫を緩和することができる。   Further, since the connecting member 13 is formed of a band-shaped member having a predetermined width in the vertical direction, the pressure applied to the user A from the connecting member 13 can be dispersed in the width direction of the connecting member 13. Local pressure can be relieved.

更に、各身体保持部材１１が内側に回動すると、各身体保持部材１１の前端側に設けた係止部１１ｂがそれぞれ車椅子１の外側から車椅子１の肘掛部７に係止するようにしたので、各身体保持部材１１が所定位置よりも内側に回動することがなく、各身体保持部材１１を常に適正な間隔に保持することができる。   Further, when each body holding member 11 is rotated inward, the locking portion 11b provided on the front end side of each body holding member 11 is locked to the armrest 7 of the wheelchair 1 from the outside of the wheelchair 1 respectively. Each body holding member 11 does not rotate inward from the predetermined position, and each body holding member 11 can always be held at an appropriate interval.

尚、前記実施形態では、車椅子１のエアバッグ２１側と接続ユニット２４とをケーブル２４を介して有線で接続するようにしたものを示したが、例えば電波や赤外線を用いた無線通信により、接続ユニット２４から車椅子１のエアバッグ２１側にエアバッグ作動信号を出力するようにしてもよい。   In the above-described embodiment, the airbag 21 side of the wheelchair 1 and the connection unit 24 are connected by wire via the cable 24. However, for example, the connection is performed by wireless communication using radio waves or infrared rays. An airbag operation signal may be output from the unit 24 to the airbag 21 side of the wheelchair 1.

また、前記実施形態では、接続ユニット２４側に制御部２５を配置したものを示したが、制御部２５を車椅子１側に配置し、車椅子搬送車９のセンサ９ｂから出力された信号を接続ユニット２４を介して車椅子１の制御部２５に入力するようにしてもよい。   In the above embodiment, the control unit 25 is disposed on the connection unit 24 side. However, the control unit 25 is disposed on the wheelchair 1 side, and a signal output from the sensor 9b of the wheelchair transport vehicle 9 is transmitted to the connection unit 24. 24 may be input to the control unit 25 of the wheelchair 1 via 24.
