Description

姿勢保持具Posture holder
　本発明は、例えば医療施設や理美容施設などで用いられる椅子に備えられる姿勢保持具に関するものである。 The present invention relates to a posture holder provided in a chair used in, for example, a medical facility or a hairdressing and beauty facility.
　従来、医療施設や理美容施設などにおいて施術される際に着座者が着座する椅子は、背もたれ部に取り付けられて着座者の背中との間に配置されるクッションが備えられたものがある。このようなクッションとして、例えば、下記特許文献１に記載された歯科用治療椅子に備えられたサポートバックがある。このサポートバックは、複数のエアバックと、各エアバックへの給排気のための幹線エアーチューブとが備えられ、この幹線エアーチューブを通じてエアバックが給排気されて膨張し、または縮小する。各エアバックが個々に制御されるため、サポートバックは、着座者の体形に合わせて様々な凹凸に調整される。 Conventionally, a chair on which a seated person sits when performing a procedure in a medical facility or a hairdressing / facility facility is provided with a cushion that is attached to the backrest portion and disposed between the back of the seated person. As such a cushion, for example, there is a support bag provided in a dental treatment chair described in Patent Document 1 below. The support bag includes a plurality of airbags and a trunk air tube for supplying / exhausting air to each airbag, and the airbag is supplied / exhausted through the trunk air tube to expand or contract. Since each airbag is controlled individually, the support bag is adjusted to various irregularities according to the body shape of the seated person.
特開２００５－２７０２１１号公報Japanese Patent Laying-Open No. 2005-270211
　しかし、特許文献１に記載されたサポートバックは、上記したとおり、複数のエアバックが備えられているため、各エアバック同士の間に隙間が形成され、この隙間が着座者の背中に適合しない場合がある。また、複数のエアバックは幹線エアーチューブで連結され、内部にエアーのみが充満しているため、エアバック内部の圧力が全体に均一である。人体荷重が加わった場合、偏って荷重が多く加わる部分が存在すると、他部分の圧力が増加し、他部分のエアバックが隆起することとなり、着座者の体形に沿った形状とはならない。例えば、高齢で円背した着座者は、円背の度合いが左右対称であるとは限らず、また、着座者の体格は、年齢、性別に応じて異なるため、すべての着座者の背中に合わせて調整し、適合させることは困難である。 However, since the support bag described in Patent Document 1 includes a plurality of airbags as described above, a gap is formed between the airbags, and this gap does not fit the back of the seated person. There is a case. In addition, since the plurality of airbags are connected by a trunk air tube and only the air is filled inside, the pressure inside the airbag is uniform throughout. When a human body load is applied, if there is a portion where a large amount of load is applied in an uneven manner, the pressure in the other portion increases, and the airbag in the other portion rises, so that the shape does not match the body shape of the seated person. For example, a seated person who is elderly and has a back is not necessarily symmetrical with respect to the back, and the physique of the seated person varies according to age and gender, so it matches the back of all seated persons. It is difficult to adjust and adapt.
　本発明は、上記の実情に鑑みて提案されたものである。すなわち、様々な着座者の背中に合わせて形状を変化させると共に、施術の工程に合わせて、適宜その変化後の形状を維持し、着座者の姿勢を保持することができる姿勢保持具の提供を目的とする。 The present invention has been proposed in view of the above circumstances. That is, it is possible to provide a posture holding tool that can change the shape according to the backs of various seated persons, maintain the shape after the change as appropriate according to the treatment process, and maintain the posture of the seated person. Objective.
　上記目的を達成するために、本発明に係る姿勢保持具は、着座者が着座する椅子の背もたれ部と前記着座者の背面との間に配置され、給気されることで前記背面の形状に沿って変形すると共に、前記背面と対面する背面対面部が前記背面と接触し、排気されることで前記背面の形状を維持する、ことを特徴とする。 In order to achieve the above object, the posture holder according to the present invention is disposed between a back portion of a chair on which a seated person sits and the back surface of the seated person, and is supplied with air so that the shape of the back surface is obtained. The back surface facing portion facing the back surface is in contact with the back surface and is evacuated to maintain the shape of the back surface.
　本発明に係る姿勢保持具は、前記背もたれ部が、傾倒後、停止して排気される、ことを特徴とする。 The posture holder according to the present invention is characterized in that the backrest portion stops and is exhausted after being tilted.
　本発明に係る姿勢保持具は、前記背もたれ部が、傾倒または起立しながら給気され、傾倒後、停止して排気される、ことを特徴とする。 The posture holder according to the present invention is characterized in that the backrest portion is supplied with air while tilting or standing, and is stopped and exhausted after tilting.
　本発明に係る姿勢保持具は、椅子に対する着脱が可能である、ことを特徴とする。 The posture holder according to the present invention is detachable from a chair.
　本発明に係る姿勢保持具は、給排気されるエアーの供給が、前記着座者の診療に用いられる器具を制御する歯科治療ユニットによって行われる、ことを特徴とする。 The posture holder according to the present invention is characterized in that supply of air to be supplied and exhausted is performed by a dental treatment unit that controls an instrument used for medical examination of the seated person.
　本発明に係る姿勢保持具は、給気されるエアーの流路である給気路と、排気されるエアーの流路である排気路と、前記排気路に備えられてエアーを排気する真空発生器と、前記真空発生器にエアーを供給する供給路と、前記給気路を開閉する給気コントローラと、前記供給路を開閉する供給コントローラと、から構成された給排気制御装置が備えられた、ことを特徴とする。 The posture holder according to the present invention includes an air supply path that is a flow path of air to be supplied, an exhaust path that is a flow path of air to be exhausted, and vacuum generation that is provided in the exhaust path and exhausts air. And a supply / exhaust control device comprising a supply path for supplying air to the vacuum generator, an air supply controller for opening and closing the air supply path, and a supply controller for opening and closing the supply path. It is characterized by that.
　本発明に係る姿勢保持具は上記した構成である。すなわち、姿勢保持具は、給気されることで、自在に形状を変形することが可能な状態となり、背面対面部が着座者の背面の形状に沿って隙間なく接触して背面に適合した形状に変形する。この状態で排気されると、姿勢保持具は背面に適合した形状を維持する。したがって、様々な着座者の背面に合わせて形状を変化させると共にその形状を維持し、着座者の姿勢を保持することができる。 The posture holder according to the present invention has the above-described configuration. In other words, the posture retainer is in a state where it can be freely deformed by being supplied with air, and the shape that fits the back side with the back facing part contacting the back of the seated person without gaps Transforms into When exhausted in this state, the posture retainer maintains a shape suitable for the back surface. Therefore, it is possible to change the shape according to the back surface of various seated persons, maintain the shape, and maintain the posture of the seated person.
　ここで、背もたれ部の傾倒と起立が繰り返される際、着座者の姿勢はその都度変化するため、初めに着座した際の着座者の背面と背面対面部との接触位置および接触する部分の形状が、背もたれ部が傾倒して横たわった際の着座者の背面と背面対面部との接触位置および接触する部分の形状と、通常異なる。再び背もたれ部が起立した際の座位の着座者の背面と背面対面部との接触位置および接触する部分の形状は、さらに変化している。すなわち、着座した着座者の背面の形状に合わせて姿勢保持具の形状を変化させても、その形状は、横たわった着座者の背面に適合しない。 Here, when the tilting and standing of the backrest are repeated, the posture of the seated person changes each time.Therefore, the contact position between the back surface and the back facing part of the seated person when seated first and the shape of the contacting part are The contact position between the back of the seated person and the back-facing part when the backrest part is inclined and lies and the shape of the contacting part are usually different. The contact position between the back surface and the back surface of the seated occupant in the sitting position when the backrest portion stands up again and the shape of the contacting portion are further changed. That is, even if the shape of the posture holder is changed in accordance with the shape of the back surface of the seated occupant, the shape does not match the back surface of the laying occupant.
　そこで、本発明に係る姿勢保持具は、背もたれ部が、傾倒または起立しながら給気され、傾倒後、停止して排気される。この構成により、姿勢保持具は、背もたれ部が傾倒し、停止する以外の場合は、形状が自在に変化可能な柔軟な状態である。すなわち、姿勢保持具は、背もたれ部が傾倒しながら給気され、着座者の背面の形状に沿って、背面対面部が背面に隙間なく接触して背面に適合した形状に変形し、背もたれ部が倒れた状態で停止すると排気され、形状が固定し、横たわった着座者の背面に適合した形状を維持する。また、姿勢保持具は、背もたれ部が起立しながら給気され、背面に適合した形状に変形する。このことにより、姿勢保持具は、着座者の姿勢が変化する毎に、その姿勢に合わせて変化するため、様々な姿勢に合わせて形状を変化させると共にその形状を維持し、着座者の姿勢を保持することができる。 Therefore, in the posture holder according to the present invention, the backrest portion is supplied with air while tilting or standing, and after being tilted, it is stopped and exhausted. With this configuration, the posture holding tool is in a flexible state in which the shape can be freely changed except when the backrest is tilted and stopped. That is, the posture holding device is supplied with the backrest portion tilting, and the back-facing portion contacts the back surface without any gap along the shape of the back surface of the seated person and deforms into a shape suitable for the back surface. When stopped in a collapsed state, it is evacuated, the shape is fixed, and the shape that fits the back of the lying occupant is maintained. In addition, the posture holder is supplied with air while the backrest portion stands up, and is deformed into a shape suitable for the back surface. As a result, each time the posture of the seated person changes, the posture holder changes according to the posture, so the shape is changed according to various postures and the shape is maintained, and the posture of the seated person is changed. Can be held.
　本発明に係る姿勢保持具は、椅子に対する着脱が可能である。したがって、既存の設備に対応させることができ、また、姿勢保持具が必要な着座者に対してのみ椅子に装着し、姿勢保持具が不要な着座者に対しては椅子から取り外すことで、着座者に応じて対応することができる。 The posture holder according to the present invention can be attached to and detached from the chair. Therefore, it can be used for existing equipment, and it can be attached to a chair only for a seated person who needs a posture holder, and can be removed from the chair for a seated person who does not need a posture holder. Depending on the person.
　本発明に係る姿勢保持具は、給排気されるエアーの供給が、着座者の診療に用いられる器具を制御する歯科治療ユニットによって行われる。すなわち、既存の設備である歯科治療ユニットによってエアーの供給が行われるため、エアーを供給するための装置を別途用意する必要がない。したがって、既存の設備に対応させることができる。 In the posture holder according to the present invention, supply of air to be supplied and exhausted is performed by a dental treatment unit that controls an instrument used for medical examination of a seated person. That is, since air is supplied by a dental treatment unit that is an existing facility, there is no need to separately prepare a device for supplying air. Therefore, it can be made to correspond to existing facilities.
　本発明に係る姿勢保持具は、給気されるエアーの流路である給気路と、排気されるエアーの流路である排気路と、排気路に備えられてエアーを排気する真空発生器と、真空発生器にエアーを供給する供給路と、給気路を開閉する給気コントローラと、供給路を開閉する供給コントローラと、から構成された給排気制御装置が備えられている。この構成により、供給路が供給コントローラによって閉塞すると共に給気路が給気コントローラによっ
て開放すると、エアーが給気路を流通して姿勢保持具に給気される。一方、給気路が給気コントローラによって閉塞すると共に供給路が供給コントローラによって開放すると、真空発生器では、供給路から流入したエアーによって真空が発生し、排気路を流通して吸引されることで姿勢保持具が排気される。したがって、給排気を制御することができる。 The posture holder according to the present invention includes an air supply path that is a flow path of air to be supplied, an exhaust path that is a flow path of air to be exhausted, and a vacuum generator that is provided in the exhaust path and exhausts air And a supply / exhaust control device comprising a supply path for supplying air to the vacuum generator, an air supply controller for opening / closing the supply path, and a supply controller for opening / closing the supply path. With this configuration, when the supply path is closed by the supply controller and the supply path is opened by the supply controller, air flows through the supply path and is supplied to the posture holder. On the other hand, when the air supply path is closed by the air supply controller and the supply path is opened by the supply controller, the vacuum generator generates a vacuum by the air flowing in from the supply path, and is sucked through the exhaust path. The posture holder is exhausted. Therefore, supply / exhaust can be controlled.

　以下に、本発明の実施形態に係る姿勢保持具を図面に基づいて説明する。図１は、本発明の実施形態に係る姿勢保持具１０の外観と、この姿勢保持具１０が装着された椅子３が示されている。 Hereinafter, a posture holder according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an appearance of a posture holder 10 according to an embodiment of the present invention and a chair 3 to which the posture holder 10 is attached.
　図１において、本発明の実施形態に係る姿勢保持具１０は、着座者１（図３参照）が着座する椅子３の背もたれ部４と着座者１の背面２（背中、または、背中と後頭部）との間に配置されるものである。姿勢保持具１０は、背もたれ部４に取り付けられた際に、背もたれ部４と対面する側が背もたれ対面部１１であり、着座者１の背面２と対面する側が背面対面部１２である。姿勢保持具１０は着脱が可能であるため、椅子３に着脱するための着脱部１３が背もたれ対面部１１に備えられている。着脱部１３は、例えば、バンド１４であれば、枕部５や背もたれ部４に巻き付けられて留められ、カバー１５であれば、枕部５の上に被せられる。 In FIG. 1, a posture holder 10 according to an embodiment of the present invention includes a backrest 4 of a chair 3 on which a seated person 1 (see FIG. 3) sits and a back surface 2 of the seated person 1 (back or back and back of the head). Between the two. When the posture holder 10 is attached to the backrest part 4, the side facing the backrest part 4 is the backrest facing part 11, and the side facing the back surface 2 of the seated person 1 is the back facing part 12. Since the posture holder 10 can be attached and detached, an attachment / detachment portion 13 for attaching / detaching to / from the chair 3 is provided on the backrest facing portion 11. For example, the detachable part 13 is wrapped around the pillow part 5 and the backrest part 4 if it is a band 14, and is put on the pillow part 5 if it is a cover 15.
　姿勢保持具１０は、ビーズのような粒状体を適量、内包しており、給排気による内部圧力のコントロールによって性質が変化する。すなわち、姿勢保持具１０は、給気されることで、密着した粒状体間の密集状態を緩和、ビーズ同士の摩擦を減少させ、柔らかな形状可変状態に変化する。一方、排気されることで姿勢保持具１０は収縮し、粒状体間が、より密集状態となる。そのため、粒状体同士が密着し、ビーズ同士の摩擦が増加するため、形状維持状態に変化する。 The posture holder 10 contains an appropriate amount of granular material such as beads, and its properties change by controlling the internal pressure by supplying and exhausting air. In other words, the posture holder 10 is supplied with air, so that the dense state between the closely-attached granular bodies is relaxed, the friction between the beads is reduced, and the shape is changed to a soft shape variable state. On the other hand, the posture holder 10 is contracted by being exhausted, and the space between the granular bodies becomes more dense. For this reason, the particles are brought into close contact with each other and the friction between the beads is increased, so that the shape is maintained.
　形状可変状態では、姿勢保持具１０は一定の形状を有さず、圧力が加えられると形状が変化する。したがって、姿勢保持具１０は、椅子３に着座した着座者１が背もたれ部４に凭れたことによって圧力が加えられると、背面２の形状に沿って変形し、背面対面部１２の全面が背面２と接触する。一方、形状維持状態では、背面対面部１２において背面２の形状が維持される。 In the shape variable state, the posture holder 10 does not have a fixed shape, and the shape changes when pressure is applied. Accordingly, when pressure is applied when the seated person 1 seated on the chair 3 falls on the backrest part 4, the posture holding tool 10 is deformed along the shape of the back surface 2, and the entire surface of the back facing part 12 is formed on the back surface 2. Contact with. On the other hand, in the shape maintaining state, the shape of the back surface 2 is maintained at the back surface facing portion 12.
　ここで、給排気は背もたれ部４の動作と連動し、背もたれ部４が傾倒または起立しながら給気され、傾倒した状態で停止して排気される。すなわち、背もたれ部４が起立した状態から傾倒した状態に変化する最中に、または傾倒した状態から起立した状態に変化する最中に、形状可変状態に変化し、背面対面部１２が着座者１の背面２の形状に沿って変形する。一方、背もたれ部４が傾倒した状態で停止して（停止した後に、または停止すと共
に）、形状維持状態に変化し、背面２の形状を維持する。この様な状態の変化を生じさせる給排気の制御は、給排気制御装置１６によって実現される。 Here, the supply / exhaust is interlocked with the operation of the backrest 4, the air is supplied while the backrest 4 is tilted or standing, and is stopped and exhausted in the tilted state. That is, while the backrest part 4 is changing from the standing state to the tilted state, or while the backrest part 4 is changing from the tilted state to the standing state, the back-to-back part 12 is changed to the seated person 1. It deforms along the shape of the back surface 2 of the. On the other hand, the backrest 4 is stopped in a tilted state (after or after being stopped), is changed to a shape maintaining state, and the shape of the back surface 2 is maintained. The supply / exhaust control that causes such a change in state is realized by the supply / exhaust control device 16.
　ここで、排気制御装置１６について図面に基づいて説明する。図２は、本発明の実施形態に係る姿勢保持具１０の給排気制御装置１６の回路の概略が示されている。 Here, the exhaust control device 16 will be described with reference to the drawings. FIG. 2 schematically shows a circuit of the air supply / exhaust control device 16 of the posture holder 10 according to the embodiment of the present invention.
　図２に示されているとおり、給排気制御装置１６は、給排気されるエアーを供給するためのエアー供給装置２４と、給気される給気エアー３２の流路である給気路１７と、排気される排気エアー３１の流路である排気路１８と、この排気路１８に備えられ排気エアー３１を排気する真空発生器１９と、この真空発生器１９に供給エアー３０を供給する供給路２３と、給気路１７を開閉する給気コントローラ２０と、供給路２３を開閉する供給コントローラ２１とから構成されている。 As shown in FIG. 2, the air supply / exhaust control device 16 includes an air supply device 24 for supplying air to be supplied and exhausted, and an air supply path 17 that is a flow path of the supplied air 32. An exhaust path 18 that is a flow path of exhaust air 31 to be exhausted, a vacuum generator 19 that is provided in the exhaust path 18 and exhausts the exhaust air 31, and a supply path that supplies the supply air 30 to the vacuum generator 19 23, an air supply controller 20 that opens and closes the air supply path 17, and a supply controller 21 that opens and closes the supply path 23.
　エアー供給装置２４は、各エアー３０，３２を供給し、給排気を行うものである。例えば、着座者１の診療に用いられるインスツルメント（図示省略）を制御する歯科治療ユニットなどである。 The air supply device 24 supplies air 30 and 32 to supply and exhaust air. For example, a dental treatment unit for controlling an instrument (not shown) used for medical treatment of the seated person 1.
　給気路１７は、例えばエアーチューブなどであり、姿勢保持具１０とエアー供給装置２４とに接続されている。また、給気路１７は、給気コントローラ２０が流路の途中に接続されている。給気コントローラ２０は、例えばバルブなどである。 The air supply path 17 is an air tube, for example, and is connected to the posture holder 10 and the air supply device 24. The air supply path 17 is connected to the air supply controller 20 in the middle of the flow path. The air supply controller 20 is, for example, a valve.
　排気路１８は、例えばエアーチューブなどであり、姿勢保持具１０と真空発生器１９とに接続され、姿勢保持具１０への流入を規制する逆止弁２２が流路の途中に接続されている。なお、排気路１８と給気路１７とは、姿勢保持具１０側において単一のエアーチューブを共有する構成であってもよい。 The exhaust path 18 is, for example, an air tube or the like, and is connected to the posture holder 10 and the vacuum generator 19, and a check valve 22 that restricts the flow into the posture holder 10 is connected in the middle of the flow path. . The exhaust passage 18 and the air supply passage 17 may be configured to share a single air tube on the posture holder 10 side.
　供給路２３は、例えばエアーチューブなどであり、真空発生器１９とエアー供給装置２４とに接続されている。また、供給路２３は、供給コントローラ２１が流路の途中に接続されている。供給コントローラ２１は、例えばバルブなどである。なお、供給路２３と給気路１７とは、エアー供給装置２４側において単一のエアーチューブを共有する構成であってもよい。 The supply path 23 is an air tube, for example, and is connected to the vacuum generator 19 and the air supply device 24. Further, the supply path 23 is connected to the supply controller 21 in the middle of the flow path. The supply controller 21 is, for example, a valve. The supply path 23 and the air supply path 17 may be configured to share a single air tube on the air supply device 24 side.
　真空発生器１９は、真空ポートに排気路１８が接続され、供給ポートに供給路２３が接続されている。 The vacuum generator 19 has an exhaust path 18 connected to a vacuum port and a supply path 23 connected to a supply port.
　上記のとおり、姿勢保持具１０が構成されている。次に、姿勢保持具１０の動作を図面に基づいて説明する。図３は、本発明の実施形態に係る姿勢保持具１０の動作の状態が示されている。 As described above, the posture holder 10 is configured. Next, operation | movement of the attitude | position holder 10 is demonstrated based on drawing. FIG. 3 shows a state of operation of the posture holder 10 according to the embodiment of the present invention.
　図３（ａ）に示されているとおり、椅子３は、枕部５にカバー１５が被せられて姿勢保持具１０が装着されている。着座者１が椅子３に着座した状態では、背もたれ部４が起立し、この背もたれ部４と着座者１の背面２との間に姿勢保持具１０が配置されている。 As shown in FIG. 3 (a), the chair 3 is provided with a posture holding tool 10 with a cover 15 placed on the pillow part 5. In a state where the seated person 1 is seated on the chair 3, the backrest part 4 stands up, and the posture holder 10 is disposed between the backrest part 4 and the back surface 2 of the seated person 1.
　背もたれ部４が起立した状態において、姿勢保持具１０は形状可変状態である。すなわち、供給コントローラ２１が供給路２３を閉塞すると共に給気コントローラ２０が給気路１７を開放し、エアー供給装置２４から供給された供給エアー３２が給気路１７を流通するため、給気された姿勢保持具１０は形状可変状態である。この状態で、各コントローラ２０，２１が閉塞することで（図２参照）、形状可変状態が維持される。 In the state where the backrest part 4 stands up, the posture holder 10 is in a variable shape state. That is, the supply controller 21 closes the supply path 23 and the air supply controller 20 opens the air supply path 17, and the supply air 32 supplied from the air supply device 24 flows through the air supply path 17. The posture holder 10 is in a variable shape state. In this state, when the controllers 20 and 21 are closed (see FIG. 2), the shape variable state is maintained.
　形状可変状態で、着座者１が椅子３に着座して背もたれ部４に凭れると、圧力が加えら
れて姿勢保持具１０の背面対面部１２は背面２の形状に沿って変形し、背面対面部１２の全面が背面２に隙間なく接触して背面２に適合した形状に変形する。 When the seated person 1 sits on the chair 3 and falls into the backrest part 4 in the shape variable state, pressure is applied and the back facing part 12 of the posture holder 10 is deformed along the shape of the back face 2, and the back facing The entire surface of the part 12 comes into contact with the back surface 2 without a gap and is deformed into a shape suitable for the back surface 2.
　図３（ｂ）に示されているとおり、背もたれ部４が傾倒すると、姿勢保持具１０は、形状可変状態を維持しながら背もたれ部４が傾倒し、横たわった着座者１の背面２に適合した形状に背面対面部１２が変化する。 As shown in FIG. 3B, when the backrest 4 is tilted, the posture retainer 10 is fitted to the back 2 of the seated person 1 lying down while the backrest 4 is tilted while maintaining the shape variable state. The back facing part 12 changes in shape.
　図３（ｃ）に示されているとおり、背もたれ部４が傾倒した状態で停止して排気されて形状維持状態に変化し、横たわった着座者１の背面２に適合した形状が維持される。すなわち、給気コントローラ２０が給気路１７を閉塞すると共に供給コントローラ２１が供給路２３を開放すると、エアー供給装置２４から供給された供給エアー３０が真空発生器１９の供給ポートから流入することで真空が発生し、排気路１８を流通して真空ポートから排気エアー３１が吸引されることで姿勢保持具１０が排気される。姿勢保持具１０は、排気されて収縮し、形状維持状態となり、各コントローラ２０，２１が閉塞することで（図２参照）、形状維持状態が維持される。 As shown in FIG. 3 (c), the backrest portion 4 stops in a tilted state and is exhausted to change to a shape maintaining state, and a shape suitable for the back surface 2 of the lying seated person 1 is maintained. That is, when the air supply controller 20 closes the air supply path 17 and the supply controller 21 opens the supply path 23, the supply air 30 supplied from the air supply device 24 flows from the supply port of the vacuum generator 19. When the vacuum is generated and the exhaust air 31 is sucked from the vacuum port through the exhaust passage 18, the posture holder 10 is exhausted. The posture holding tool 10 is exhausted and contracts to be in a shape maintaining state, and when the controllers 20 and 21 are closed (see FIG. 2), the shape maintaining state is maintained.
　再び背もたれ部４が起立すると、姿勢保持具１０は形状可変状態に変化する（図３（ａ）参照）。 When the backrest 4 rises again, the posture holder 10 changes to a shape variable state (see FIG. 3A).
　上記のとおり、姿勢保持具１０は動作する。ここで、本実施形態の変形例によれば、次のような動作が可能である。図４は、本発明の実施形態の変形例に係る姿勢保持具１０の動作の状態が示されている。 As described above, the posture holder 10 operates. Here, according to the modification of the present embodiment, the following operation is possible. FIG. 4 shows an operation state of the posture holder 10 according to the modification of the embodiment of the present invention.
　図４（ａ）に示されているとおり、背もたれ部４が起立した状態における形状可変状態で、着座者１が椅子３に着座して背もたれ部４に凭れた後、図４（ｂ）に示されているとおり、姿勢保持具１０が形状維持状態に変化し、着座した着座者１の背面２に適合した形状を維持する。すなわち、給気コントローラ２０が給気路１７を閉塞すると共に供給コントローラ２１が供給路２３を開放すると、エアー供給装置２４から供給された供給エアー３０が真空発生器１９の供給ポートから流入することで真空が発生し、排気路１８を流通して真空ポートから排気エアー３１が吸引されることで姿勢保持具１０が排気される。姿勢保持具１０は、排気されて収縮し、形状維持状態となり、各コントローラ２０，２１が閉塞することで（図２参照）、形状維持状態が維持される。すなわち、着座した着座者１の背面２に適合した形状で背面対面部１２が維持される。 As shown in FIG. 4 (a), after the seated person 1 sits on the chair 3 and falls into the backrest part 4 in a shape-variable state with the backrest part 4 standing up, it is shown in FIG. 4 (b). As shown, the posture holder 10 changes to the shape maintaining state, and maintains the shape suitable for the back surface 2 of the seated occupant 1. That is, when the air supply controller 20 closes the air supply path 17 and the supply controller 21 opens the supply path 23, the supply air 30 supplied from the air supply device 24 flows from the supply port of the vacuum generator 19. When the vacuum is generated and the exhaust air 31 is sucked from the vacuum port through the exhaust passage 18, the posture holder 10 is exhausted. The posture holding tool 10 is exhausted and contracts to be in a shape maintaining state, and when the controllers 20 and 21 are closed (see FIG. 2), the shape maintaining state is maintained. That is, the back-facing portion 12 is maintained in a shape suitable for the back 2 of the seated occupant 1.
　その後、図４（ｃ）に示されているとおり、背もたれ部４が傾倒すると、姿勢保持具１０は、背もたれ部４が傾倒しながら給気されて形状可変状態に変化し、横たわった着座者１の背面２に適合した形状に背面対面部１２が変化する。背もたれ部４が傾倒した状態で停止して排気されて形状維持状態に変化し、各コントローラ２０，２１が閉塞することで（図２参照）、形状維持状態が維持される。すなわち、横たわった着座者１の背面２に適合した形状が維持される。 Thereafter, as shown in FIG. 4 (c), when the backrest part 4 is tilted, the posture holder 10 is supplied with the backrest part 4 being tilted to change into a shape-variable state, and the laying seater 1 The back surface facing portion 12 changes to a shape suitable for the back surface 2 of the back surface. When the backrest 4 is tilted, it stops and is exhausted to change to the shape maintaining state, and the controllers 20 and 21 are closed (see FIG. 2), so that the shape maintaining state is maintained. That is, the shape suitable for the back surface 2 of the seated person 1 who lies down is maintained.
　また、背もたれ部４が再び起立すると、姿勢保持具１０は、背もたれ部４が起立しながら給気されて形状可変状態に変化し、着座した着座者１の背面２に適合した形状に背面対面部１２が変化する（図４（ａ）参照）。 Further, when the backrest part 4 stands up again, the posture holder 10 is supplied with air while the backrest part 4 stands up and changes to a shape-variable state, and the back-to-back part has a shape suitable for the back surface 2 of the seated seated person 1. 12 changes (see FIG. 4A).
　図４（ｂ）に示されているとおり、姿勢保持具１０は、背もたれ部４が起立した状態で停止して排気されて形状維持状態に変化し、着座した着座者１の背面２に適合した形状で背面対面部１２が維持される。この状態で、各コントローラ２０，２１が閉塞することで（図２参照）、形状維持状態が維持される。 As shown in FIG. 4 (b), the posture holder 10 is stopped while the backrest portion 4 is standing up and evacuated to change into a shape maintaining state, and is adapted to the back surface 2 of the seated seated person 1. The back face-to-face part 12 is maintained in shape. In this state, when the controllers 20 and 21 are closed (see FIG. 2), the shape maintaining state is maintained.
　次に、本実施形態の効果を説明する。 Next, the effect of this embodiment will be described.
　上記したとおり、本実施形態によれば、姿勢保持具１０は、給気されることで形状可変状態に変化し、一方、排気されることで収縮して形状維持状態に変化する。形状可変状態では、姿勢保持具１０は一定の形状を有さず、圧力が加えられると形状が変化する。したがって、姿姿勢保持具１０は、椅子３に着座した着座者１が背もたれ部４に凭れたことによって圧力が加えられると、着座者１の背面２の形状に沿って変形し、背面対面部１２の全面が背面２に隙間なく接触して背面２に適合した形状に変形する。一方、形状維持状態では、姿勢保持具１０は、背面２に適合した形状を維持する。したがって、様々な着座者１の背面２に合わせて形状を変化させると共にその形状を維持し、着座者１の姿勢を保持することができる。 As described above, according to the present embodiment, the posture holder 10 changes to the shape variable state when supplied with air, and contracts and changes to the shape maintaining state when exhausted. In the shape variable state, the posture holder 10 does not have a fixed shape, and the shape changes when pressure is applied. Therefore, when a pressure is applied when the seated person 1 seated on the chair 3 falls on the backrest part 4, the posture / position holding tool 10 is deformed along the shape of the back surface 2 of the seated person 1, and the back facing part 12. The entire surface contacts the back surface 2 without a gap and deforms into a shape suitable for the back surface 2. On the other hand, in the shape maintaining state, the posture holding tool 10 maintains a shape suitable for the back surface 2. Therefore, the shape can be changed according to the back surface 2 of various seated persons 1, and the shape can be maintained, and the position of the seated person 1 can be maintained.
　本実施形態によれば、背もたれ部４が起立した状態から傾倒した状態に変化する最中に、または傾倒した状態から起立した状態に変化する最中に、形状可変状態に変化し、背面対面部１２が着座者１の背面２の形状に沿って、背面対面部１２の全面が背面２に隙間なく接触して背面２に適合した形状に変形する。一方、背もたれ部４が傾倒した状態で停止して、形状維持状態に変化し、横たわった着座者１の背面２に適合した形状を維持する。このことにより、姿勢保持具１０は、着座者１の姿勢が変化する毎に、その姿勢に合わせて変化するため、様々な姿勢に合わせて形状を変化させると共にその形状を維持し、着座者１の姿勢を保持することができる。 According to the present embodiment, the backrest portion 4 changes to the shape variable state during the change from the standing state to the tilted state, or during the change from the tilted state to the standing state, and the back facing portion 12, along the shape of the back surface 2 of the seated person 1, the entire surface of the back facing portion 12 is brought into contact with the back surface 2 without a gap and deformed into a shape suitable for the back surface 2.
