Description

本発明は、車両用シートに関する。より詳しくは、着座者の触覚を刺激する機構を備えた車両用シートに関する。   The present invention relates to a vehicle seat. More specifically, the present invention relates to a vehicle seat provided with a mechanism for stimulating the sense of touch of a seated person.

従来、着座者の触覚を刺激する機構として振動体を備える車両用シートがあり、例えば下記特許文献1に開示されている。特許文献1に係る車両用シートには、座部を構成するクッション材の下面に形成された凹部内に振動体が配置されている。センサにより障害物を検知すると振動体が振動し、その振動がクッション材を介して着座者に伝達されることにより着座者の触覚を刺激して障害物を報知することができるものである。   Conventionally, there is a vehicle seat provided with a vibrating body as a mechanism for stimulating the tactile sensation of a seated person. In the vehicle seat according to Patent Document 1, a vibrating body is disposed in a recess formed in the lower surface of a cushion material constituting the seat. When an obstacle is detected by the sensor, the vibrating body vibrates, and the vibration is transmitted to the seated person via the cushion material, so that the tactile sense of the seated person can be stimulated to notify the obstacle.

特開2006−341839号公報JP 2006-341839 A

振動体により着座者の触覚を刺激する場合、振動体の配設位置が座面に近いほど着座者に振動を伝達しやすい。しかし、振動体の配設位置が座面に近いほど、振動体が作動していないときにも着座者が異物感を感じやすく、乗り心地が損なわれやすい。振動体を座面から離れた位置に配置すれば振動体が作動していないときの乗り心地は確保することができるが、振動体の作動時に着座者に振動が伝わりにくくなる。したがって、振動体を用いた場合、着座者の触覚を刺激しない非作動時の乗り心地の良さを確保しながら着座者の触覚を刺激する作動時に十分に振動を伝達するのは困難であった。   When the tactile sense of the seated person is stimulated by the vibrating body, the vibration is easily transmitted to the seated person as the position of the vibrating body is closer to the seating surface. However, the closer the vibration body is disposed to the seating surface, the more easily a seated person feels a foreign object even when the vibration body is not operating, and the ride comfort is likely to be impaired. If the vibrating body is arranged at a position away from the seating surface, the ride comfort when the vibrating body is not operating can be ensured, but the vibration is less likely to be transmitted to the seated person when the vibrating body is operating. Therefore, when a vibrating body is used, it has been difficult to sufficiently transmit vibration during operation that stimulates the tactile sensation of the seated person while ensuring good riding comfort during non-operation that does not stimulate the tactile sense of the seated person.

本発明が解決しようとする課題は、着座者の触覚を十分に刺激することが可能でありながら、着座者の触覚を刺激しないときの乗り心地の良さを確保することのできる車両用シートを提供することにある。   The problem to be solved by the present invention is to provide a vehicle seat that can sufficiently stimulate the tactile sensation of the seated person but can ensure good riding comfort when the tactile sense of the seated person is not stimulated. There is to do.

本発明は、上記課題を解決するために以下の手段をとる。
第1の発明は、着座者の触覚を刺激する機構を備えた車両用シートであって、
前記着座者の触覚を刺激する機構は、着座者を刺激することのできる刺激素子を備え、該刺激素子の移動を着座者が触覚により認識することのできるシート表面近くの位置に形成された刺激素子を移動可能とする刺激付与通路と、着座者が触覚により認識することのできないシート表面から離れた位置に形成された刺激素子を退避させることのできる退避空間部とが接続されて形成されており、着座者の触覚を刺激するときには前記刺激素子を前記刺激付与通路で移動させて着座者の触覚を刺激し、着座者の触覚を刺激しないときには前記刺激素子を前記退避空間部へ退避させることを特徴とする車両用シートである。
また第1の発明は、前記刺激素子は球形状等の塊状部材で形成されており、前記刺激付与通路と前記退避空間部とは環状に接続された環状通路として形成されているとともに、前記刺激付与通路は前記塊状部材の刺激素子が移動する際に追従変形することのできる柔軟な管状部材で形成されており、前記環状通路には前記塊状部材の刺激素子を該環状通路内を循環駆動させるポンプ装置が付設されており、前記塊状部材の刺激素子が該刺激付与通路を移動することにより着座者の触覚を刺激することを特徴とする車両用シートである
The present invention takes the following means in order to solve the above problems.
A first invention is a vehicle seat provided with a mechanism for stimulating a tactile sense of a seated person,
The mechanism for stimulating the tactile sensation of the seated person includes a stimulating element capable of stimulating the seated person, and the stimulus formed at a position near the seat surface where the seated person can recognize the movement of the stimulating element by tactile sense. It is formed by connecting a stimulus applying passage that allows the element to move and a retracting space portion that can retract a stimulating element formed at a position away from the seat surface that cannot be recognized by the tactile sense. When stimulating the tactile sensation of the seated person, the stimulating element is moved in the stimulus applying path to stimulate the tactile sense of the seated person, and when not stimulating the tactile sense of the seated person, the stimulating element is retreated to the retreat space portion. A vehicle seat characterized by the above.
According to a first aspect of the present invention, the stimulation element is formed of a massive member such as a spherical shape, and the stimulation applying passage and the retracting space are formed as an annular passage connected in an annular shape, and the stimulation The application passage is formed of a flexible tubular member that can follow and deform when the stimulating element of the massive member moves, and the stimulating element of the massive member is circulated and driven in the annular passage. A vehicular seat characterized in that a pump device is attached, and the stimulating element of the massive member stimulates the tactile sensation of the seated person by moving through the stimulus applying passage .

第1の発明によれば、着座者の触覚を刺激するときには、刺激素子の移動を着座者が触覚により認識することのできるシート表面近くの位置に形成された刺激付与通路で刺激素子を移動させるので、着座者の触覚に刺激を付与することが可能である。一方、着座者の触覚を刺激しないときには、着座者が触覚により認識することのできないシート表面から離れた位置に形成された退避空間部に刺激素子を退避させるため、着座者に刺激素子による異物感を感じさせることがなく、乗り心地の良さを確保することが可能である。
また第1の発明によれば、シート表面近くの位置に設けられた刺激付与通路が塊状部材の刺激素子が移動する際に追従変形することのできる柔軟な管状部材で形成されている。そのため、着座者に塊状部材の移動を感じさせることができるとともに、塊状部材を退避空間部に退避させれば、着座者に刺激付与通路による違和感を生じさせにくく、より乗り心地を確保しやすい。
According to the first invention, when stimulating the tactile sensation of the seated person, the stimulating element is moved by the stimulus applying path formed at a position near the seat surface where the seated person can recognize the tactile sense by tactile sense. Therefore, it is possible to give a stimulus to the tactile sense of the seated person. On the other hand, when the tactile sensation of the seated person is not stimulated, the stimulating element is retracted in a retreat space formed at a position away from the seat surface that cannot be recognized by the tactile sense. It is possible to ensure a good ride comfort.
According to the first invention, the stimulus applying passage provided near the sheet surface is formed of a flexible tubular member that can be deformed following the movement of the stimulating element of the massive member. Therefore, it is possible to make the seated person feel the movement of the massive member, and if the massive member is retracted in the retreat space portion, it is difficult for the seated person to feel uncomfortable due to the stimulus applying passage, and it is easier to secure the ride comfort.

上記第1の発明によれば、着座者の触覚を十分に刺激することが可能でありながら、着座者の触覚を刺激しないときの乗り心地の良さを確保することができる。また第1の発明によれば、着座者の触覚を刺激しないときには、着座者に刺激付与通路による違和感をも生じさせにくく、より乗り心地を確保しやすい。 According to the first aspect of the invention, it is possible to sufficiently stimulate the tactile sensation of the seated person, while ensuring good riding comfort when the tactile sense of the seated person is not stimulated. According to the first invention, when the tactile sensation of the seated person is not stimulated, it is difficult for the seated person to feel uncomfortable due to the stimulus applying passage, and the riding comfort is more easily secured.

[実施形態1]
図1〜3を参照しながら本発明の実施形態1(参考例)について説明する。図1に示されるように、本実施形態のシート10は、座面となるシートクッション12、背凭れとなるシートバック14および頭を支えるヘッドレスト16を主体として構成された車両用のシートであり、シートクッション12に本発明が適用されている。各図において矢印で示すF,Uはシート10の前方,上方を示している。
[Embodiment 1]
A first embodiment (reference example) of the present invention will be described with reference to FIGS. As shown in FIG. 1, a seat 10 according to the present embodiment is a vehicle seat mainly composed of a seat cushion 12 serving as a seating surface, a seat back 14 serving as a backrest, and a headrest 16 that supports a head. The present invention is applied to the seat cushion 12. In each figure, F and U indicated by arrows indicate the front and upper sides of the seat 10.

シートクッション12は、図2に示されるように、基本的構成として、上面に薄いスポンジ材20aが一体的に配設されたシートパッド20と、該シートパッド20を被覆して着座者を支持するシート表面24を構成する表皮材22とを備えている。このシートクッション12には、着座者の触覚を刺激する機構30が内部に組み込み装備されている。着座者の触覚を刺激する機構30は、図1に示されるように、着座者の左右の大腿部の触覚を刺激することのできる位置に、シート10の前後方向に沿って配設されている。この着座者の触覚を刺激する機構30は、検知手段(図示省略)により着座者の居眠りや車両の車線逸脱等を検知し、該検知情報に基づき、着座者の触覚を刺激して警報を発することができるものである。   As shown in FIG. 2, the seat cushion 12 has, as a basic configuration, a seat pad 20 in which a thin sponge material 20a is integrally disposed on an upper surface, and covers the seat pad 20 to support a seated person. The skin material 22 which comprises the sheet | seat surface 24 is provided. The seat cushion 12 is equipped with a mechanism 30 for stimulating the sense of touch of the seated person. As shown in FIG. 1, the mechanism 30 for stimulating the tactile sense of the seated person is disposed along the front-rear direction of the seat 10 at a position where the tactile sense of the left and right thighs of the seated person can be stimulated. Yes. The mechanism 30 for stimulating the tactile sensation of the seated person detects the drowsiness of the seated person or the lane departure of the vehicle by the detecting means (not shown), and generates a warning by stimulating the tactile sense of the seated person based on the detected information. It is something that can be done.

着座者の触覚を刺激する機構30は、球形状の塊状部材40と該塊状部材40が通過することのできる刺激付与通路32と退避空間部34とを備えている。
刺激付与通路32と退避空間部34とは一続きの柔軟なチューブ36により形成されている。チューブ36はシートパッド20を厚み方向に貫通し、シートパッド20の表面側と裏面側とに掛け渡されて環状に配設されている。刺激付与通路32は、該刺激付与通路32を塊状部材40が移動すると着座者の触覚を刺激することのできるシート表面24に近い位置に設定されている。すなわち、シートパッド20の表面に沿って、シートパッド20と表皮材22との間に配設されたチューブ36の一部分36aが刺激付与通路32として設定されている。退避空間部34は、着座者が触覚により認識することのできないシート表面24から離れた位置に設定されている。つまり、チューブ36の刺激付与通路32として設定されている一部分36aを除く他の部分が退避空間部34として設定されており、シートパッド20を貫通する部分36cとシートパッド20の裏面側に配設された部分36bとが退避空間部34を構成している。
The mechanism 30 for stimulating the tactile sensation of the seated person includes a spherical block 40, a stimulus applying passage 32 through which the block 40 can pass, and a retreat space 34.
The stimulus applying passage 32 and the retreat space 34 are formed by a continuous flexible tube 36. The tube 36 penetrates the seat pad 20 in the thickness direction, and is arranged in an annular shape so as to be spanned between the front surface side and the back surface side of the seat pad 20. The stimulus applying passage 32 is set at a position close to the seat surface 24 where the tactile sense of the seated person can be stimulated when the massive member 40 moves in the stimulus applying passage 32. That is, a portion 36 a of the tube 36 disposed between the seat pad 20 and the skin material 22 is set as the stimulus applying passage 32 along the surface of the seat pad 20. The evacuation space 34 is set at a position away from the seat surface 24 that cannot be recognized by the tactile sense. In other words, the portion other than the portion 36 a set as the stimulus applying passage 32 of the tube 36 is set as the retreat space portion 34, and is disposed on the portion 36 c that penetrates the seat pad 20 and the back side of the seat pad 20. The portion 36b thus formed constitutes the retreat space 34.

塊状部材40は3個備えられており、各塊状部材40は紐状部材42に係止されて相互に連結された状態でチューブ36内に配設されている。紐状部材42は環状に形成されており、塊状部材40は紐状部材42の周方向の一部分において一定間隔を置いて係止されている。紐状部材42は、塊状部材40の係止されていない周方向の他の部分には一定間隔を置いて塊状部材40に比して極めて小さい球状突起44が設けられている。球状突起44ないし塊状部材40がモータにより回転する歯車46に噛み合うことにより紐状部材42はチューブ36内を循環可能とされている。塊状部材40、紐状部材42、歯車46(モータ)が、本発明の刺激素子、駆動伝達部材、駆動手段に相当する。   Three lump members 40 are provided, and each lump member 40 is disposed in the tube 36 while being locked to a string-like member 42 and connected to each other. The string-like member 42 is formed in an annular shape, and the massive member 40 is locked at a certain interval in a part of the string-like member 42 in the circumferential direction. The string-like member 42 is provided with spherical projections 44 that are extremely small compared to the massive member 40 at other intervals in the circumferential direction where the massive member 40 is not locked. The string-like member 42 can be circulated in the tube 36 by the spherical protrusion 44 or the massive member 40 meshing with a gear 46 rotated by a motor. The massive member 40, the string-like member 42, and the gear 46 (motor) correspond to the stimulation element, the drive transmission member, and the drive means of the present invention.

以上の構成の着座者の触覚を刺激する機構30の作動について説明する。着座者の触覚を刺激する機構30は、検知手段(図示省略)により着座者の居眠りや車両の車線逸脱等を検知し、警報を発するときは、モータにより歯車46を回転さることによりチューブ36内で紐状部材42を循環させる。塊状部材40が刺激付与通路32を移動することにより着座者の触覚を刺激することができる。刺激付与通路32を構成するチューブ36は少なくとも塊状部材40が移動する際に追従変形可能な程度に柔軟であり、着座者の荷重とシートパッド20の弾発力により弾性変形し、つぶれて平たくなっているが、チューブ36が塊状部材40に追従して変形することで塊状部材40が刺激付与通路32内を移動することが許容される。そのため、着座者に塊状部材40が移動するのを触覚で認識させることができ、警報を発することができる。警報を発しないときには、全ての塊状部材40が退避空間部34にある状態でモータによる紐状部材42の循環を停止させる。それにより、塊状部材40を着座者が触覚により認識することができない位置に塊状部材40を退避させる。 The operation of the mechanism 30 for stimulating the tactile sensation of the seated person having the above configuration will be described. Mechanism 30 to stimulate the tactile of the seated person detects deviation from the lane or the like of the dozing and the vehicle occupant by the detection means (not shown), when issuing an alarm, the tube by Rukoto rotate the gear 46 by the motor The string-like member 42 is circulated in 36. The tactile sense of the seated person can be stimulated by the mass member 40 moving through the stimulus applying passage 32. The tube 36 constituting the stimulus applying passage 32 is flexible enough to follow and deform at least when the massive member 40 moves, elastically deformed by the load of the seated person and the elastic force of the seat pad 20, and flattened. However, the massive member 40 is allowed to move in the stimulus applying passage 32 by the tube 36 being deformed following the massive member 40. Therefore, it is possible to make the seated person recognize the movement of the massive member 40 with a tactile sense and to issue an alarm. When the alarm is not issued, the circulation of the string-like member 42 by the motor is stopped in a state where all the massive members 40 are in the retreat space 34. Thereby, the block member 40 is retracted to a position where the seated person cannot recognize the block member 40 by touch.

以上の構成のシートクッション12によれば以下の作用効果を奏する。
着座者の触覚を刺激するときには、シート表面24近くの位置に設けられた刺激付与通路32で塊状部材40を移動させるため着座者の触覚を十分に刺激することが可能である。その一方、着座者の触覚を刺激しないときには、シート表面24から離れた位置にある着座者が触覚により認識することのできない退避空間部34に塊状部材40を退避させるため、着座者に塊状部材40による異物感を感じさせることがなく、乗り心地の良さを確保することができる。
また、塊状部材40は紐状部材42に係止されており、紐状部材42に連れ回されて移動する構成となっている。そのため、塊状部材40をより円滑に移動させることができ、警報を発するときにより確実に着座者の触覚を刺激することができるとともに、警報を発するのを止めるときには塊状部材40を退避空間部34へ円滑に移動させて着座者に異物感を生じさせない乗り心地の良い状態へスムーズに移行することができる。
According to the seat cushion 12 of the above structure, there exist the following effects.
When stimulating the tactile sensation of the seated person, the block member 40 is moved by the stimulus applying passage 32 provided at a position near the seat surface 24, so that the tactile sense of the seated person can be sufficiently stimulated. On the other hand, when the occupant's tactile sensation is not stimulated, the occupant retreats the lumped member 40 to the evacuation space 34 that cannot be recognized by the tactile sensation at a position away from the seat surface 24. It is possible to ensure a good ride comfort without feeling a foreign body feeling.
In addition, the massive member 40 is locked to the string-like member 42 and is moved along with the string-like member 42. Therefore, the lump member 40 can be moved more smoothly, and the tactile sensation of the seated person can be more reliably stimulated when an alarm is issued, and the lump member 40 is moved to the retreat space 34 when the alarm is stopped. It is possible to smoothly shift to a comfortable state where the seat is moved smoothly and does not cause a foreigner feeling to the seated person.

なお、本実施形態において塊状部材40の個数は1個でも複数でもよい。塊状部材40を複数備える場合は、同時に全ての塊状部材40が退避空間部34に収容可能なように紐状部材42の周方向の一部に係止されていれば、その個数は特に限定されない。
また、本実施形態において、刺激付与通路は、例えば、シートパッド20の表面に塊状部材40を案内することができ塊状部材40が埋没しない程度に浅い溝として形成してもよい。
また、本実施形態において、駆動伝達部材は紐状部材42に変えて例えば、ベルト状、チェーン状等の部材を適用してもよい。
In the present embodiment, the number of the massive members 40 may be one or plural. In the case where a plurality of massive members 40 are provided, the number of the massive members 40 is not particularly limited as long as all the massive members 40 are locked to a part of the string-like member 42 in the circumferential direction so that they can be accommodated in the retreat space 34 at the same time. .
Moreover, in this embodiment, the stimulus imparting passage may be formed as a groove that is shallow enough to guide the block member 40 to the surface of the seat pad 20 so that the block member 40 is not buried.
In the present embodiment, the drive transmission member may be a belt-like or chain-like member instead of the string-like member 42.

[実施形態2]
図4,5を参照しながら本発明の実施形態2について説明する。本実施形態に係るシートクッション13は、着座者の触覚を刺激する機構として上記実施形態1の着座者の触覚を刺激する機構30とは異なる機構を備えているが、シートクッションの基本的構成は変更を要しないため、図中に上記実施形態1と同じ符号で示し、詳細な説明は省略する。
[Embodiment 2]
A second embodiment of the present invention will be described with reference to FIGS. The seat cushion 13 according to the present embodiment includes a mechanism different from the mechanism 30 for stimulating the tactile sensation of the seated person according to the first embodiment as a mechanism for stimulating the tactile sense of the seated person, but the basic configuration of the seat cushion is as follows. Since no change is required, the same reference numerals as those in the first embodiment are used in the drawing, and detailed description thereof is omitted.

シートクッション13に備えられた着座者の触覚を刺激する機構50は、複数の球形状の塊状部材60を備えるとともに、該塊状部材60の移動を可能とする刺激付与通路52と、該塊状部材60を刺激付与通路52から離れた位置に格納することのできる退避空間部54とを備えている。
刺激付与通路52は、該刺激付与通路52を塊状部材60が移動すると着座者の触覚を刺激することのできるシート表面24に近い位置に設けられている。刺激付与通路52は、シートパッド20の表面に沿って、シートパッド20と表皮材22との間にチューブ56が配設されることにより形成されている。このチューブ56は、塊状部材60が移動する際に塊状部材60に追従して弾性変形可能な柔軟性を有する。退避空間部54は、箱型であり、シートパッド20の裏面側の着座者が触覚により認識することのできない位置に設けられている。退避空間部54には、内部から外部へ塊状部材60を通過させることのできる逆流防止弁55aを備えた出口54aと、外部から内部へ塊状部材60を通過させることのできる逆流防止弁55bを備えた入り口54bとが設けられている。刺激付与通路52を構成するチューブ56の両端が延長されシートパッド20を厚み方向に貫通し、その一端56a側の側壁には退避空間部54の出口54aが接続され、その他端56b側の端部が退避空間部54の入り口54bに接続されている。それにより、刺激付与通路52と退避空間部54とは環状通路として連結されている。
The mechanism 50 for stimulating the sense of touch of the seated person provided in the seat cushion 13 includes a plurality of spherical massive members 60, a stimulus applying passage 52 that enables movement of the massive members 60, and the massive members 60. And a retreat space portion 54 that can be stored at a position away from the stimulus applying passage 52.
The stimulus applying passage 52 is provided at a position close to the seat surface 24 where the tactile sense of the seated person can be stimulated when the massive member 60 moves in the stimulus applying passage 52. The stimulus applying passage 52 is formed by arranging a tube 56 between the seat pad 20 and the skin material 22 along the surface of the seat pad 20. The tube 56 has a flexibility that can elastically deform following the massive member 60 when the massive member 60 moves. The retreat space 54 has a box shape and is provided at a position where a seated person on the back side of the seat pad 20 cannot recognize by tactile sense. The retreat space portion 54 includes an outlet 54a having a backflow prevention valve 55a through which the block member 60 can pass from the inside to the outside, and a backflow prevention valve 55b through which the block member 60 can pass from the outside to the inside. And an entrance 54b. Both ends of the tube 56 constituting the stimulus applying passage 52 are extended and penetrate the seat pad 20 in the thickness direction, and the outlet 54a of the retreat space 54 is connected to the side wall on the one end 56a side, and the end on the other end 56b side Is connected to the entrance 54 b of the retreat space 54. Thereby, the stimulus applying passage 52 and the retreat space portion 54 are connected as an annular passage.

側壁が退避空間部54の出口54aが連結されたチューブ56の一端56a側の端部には、シートパッド20の裏面側に設置されたエアポンプ62が接続されている。エアポンプ62は、図4中に矢印で示すように、チューブ56内へ空気送ることのできるものであり、該エアポンプ62の送風によりチューブ56に沿って塊状部材60を移動させて刺激付与通路52と退避空間部54とを循環させることができる。すなわち、塊状部材60は、エアポンプ62の送風によりシートパッド20の裏面側からシート表面24側へ移動し、刺激付与通路52を経由してシートパッド20の裏面側へ戻ってくる。チューブ56には、他端56b側のシートパッド20の裏面側の位置に排気部57が形成されており、エアポンプから送られてきた空気は該排気部57からチューブ56の外へ排気される。チューブ56はシートパッド20の裏面側で退避空間部54に向けて下る方向に傾斜して配設されており、排気部57を通過した塊状部材60は惰性と重力により退避空間部54へ戻ってくる。 An air pump 62 installed on the back side of the seat pad 20 is connected to the end of the tube 56 to which the side wall is connected to the outlet 54 a of the retreat space 54. The air pump 62 is capable of sending air into the tube 56 as indicated by an arrow in FIG. 4, and the stimulating passage 52 is moved by moving the massive member 60 along the tube 56 by blowing air from the air pump 62. And the retreat space 54 can be circulated. That is, the massive member 60 moves from the back surface side of the seat pad 20 to the seat surface 24 side by the air blow of the air pump 62, and returns to the back surface side of the seat pad 20 via the stimulus applying passage 52. An exhaust part 57 is formed in the tube 56 at a position on the back surface side of the seat pad 20 on the other end 56 b side, and air sent from the air pump is exhausted from the exhaust part 57 to the outside of the tube 56. The tube 56 is disposed on the back surface side of the seat pad 20 so as to be inclined downward toward the retreat space portion 54, and the massive member 60 that has passed through the exhaust portion 57 returns to the retraction space portion 54 due to inertia and gravity. come.

以上の構成の着座者の触覚を刺激する機構50の作動について説明する。着座者の触覚を刺激する機構50は、検知手段(図示省略)により着座者の居眠りや車両の車線逸脱等を検知すると、退避空間部54の出口54aの逆流防止弁55aと入り口54bの逆流防止弁55bとを開放し、塊状部材60が刺激付与通路52と退避空間部54とを循環することのできる状態とする。それとともに、エアポンプ62によりチューブ56内へ空気を送り、塊状部材60を刺激付与通路52と退避空間部54とで循環させる。塊状部材60はチューブ56を弾性変形させながら刺激付与通路52を移動し、着座者に塊状部材60が移動するのを触覚で認識させて警報を発することができる。本実施形態においては、刺激付与通路52がシートの前後方向に沿って設けられており、着座者は通常姿勢において、塊状部材40が後方から前方へ移動するの大腿部で認識することとなる。警報を発するのを止めるときは、退避空間部54の出口54aの逆流防止弁55aを閉鎖し、全ての塊状部材60が退避空間部54に戻った状態で退避空間部54の入り口54bの逆流防止弁55bを閉鎖して退避空間部54をチューブ56とは遮断し、エアポンプ62の送風を停止する。それにより、塊状部材60を退避空間部54に格納状態として退避させる。 The operation of the mechanism 50 that stimulates the tactile sensation of the seated person having the above configuration will be described. The mechanism 50 for stimulating the tactile sense of the seated person detects the backflow prevention valve 55a at the outlet 54a of the retreat space 54 and the backflow prevention at the inlet 54b when detecting the drowsiness of the seated person or the lane departure of the vehicle by the detecting means (not shown). The valve 55b is opened so that the massive member 60 can circulate through the stimulus applying passage 52 and the retreat space 54. At the same time, air is sent into the tube 56 by the air pump 62, and the massive member 60 is circulated through the stimulus applying passage 52 and the retreat space 54. The massive member 60 moves along the stimulus applying passage 52 while elastically deforming the tube 56, and can alert the seated person to the movement of the massive member 60 with a tactile sensation. In this embodiment, the stimulating passage 52 is provided along the longitudinal direction of the seat, the seat occupant in the normal position, and recognizing that the massive member 40 is moved from the rear to the front in the thigh Become. When stopping issuing an alarm, the backflow prevention valve 55a at the outlet 54a of the evacuation space 54 is closed, and the backflow prevention at the entrance 54b of the evacuation space 54 is performed in a state where all the mass members 60 have returned to the evacuation space 54. The valve 55b is closed to block the retreat space 54 from the tube 56, and the air pump 62 stops blowing. Thereby, the massive member 60 is retracted in the retracted space portion 54 in a retracted state.

以上の構成のシートクッション13によれば以下の作用効果を奏する。
刺激付与通路52が柔軟であり、着座者の触覚を刺激するときには、塊状部材60が刺激付与通路52を追従変形させながら移動するため、着座者の触覚をより確実に刺激することができる。着座者の触覚を刺激しないときには、着座者が触覚により認識することのできない退避空間部54に塊状部材60が格納されるため、着座者に塊状部材60による異物感を感じさせることがなく、また、シート表面24の近くに設けられた刺激付与通路52が柔軟であるため、着座者に刺激付与通路52による異物感をも生じさせにくい。
According to the seat cushion 13 of the above structure, there exist the following effects.
When the stimulus imparting passage 52 is flexible and stimulates the tactile sensation of the seated person, the massive member 60 moves while following the stimulus imparting passage 52, so that the tactile sense of the seated person can be stimulated more reliably. When the tactile sense of the seated person is not stimulated, the massive member 60 is stored in the evacuation space portion 54 that cannot be recognized by the tactile sense, so that the seated person does not feel a foreign object feeling due to the massive member 60. In addition, since the stimulus applying passage 52 provided near the seat surface 24 is flexible, it is difficult for a seated person to feel a foreign object feeling due to the stimulus applying passage 52.

なお、本実施形態の着座者の触覚を刺激する機構50は、刺激付与通路を弁により切り替え可能な複数経路設定し、その経路を切り替えることにより大腿部に限らず着座者の複数部位を選択的に刺激する構成とすることも可能である。   The mechanism 50 for stimulating the tactile sensation of the seated person of the present embodiment sets a plurality of paths that can be switched by a valve for the stimulus applying passage, and selects a plurality of parts of the seated person as well as the thighs by switching the path. It is also possible to make a configuration that stimulates the target.
