Description
本発明は、ベルト式座位保持具の改良、詳しくは、車椅子等に座った着座者に不快感が生じない状態で着座位置を固定することができ、また、着座者の下肢のふらつきや着座姿勢の崩れも防止でき、しかも、体型の異なる着座者に対しても柔軟に対応できるベルト式座位保持具に関するものである。 The present invention is an improvement of a belt-type sitting position holder, and more specifically, a seating position can be fixed without causing discomfort to a seated person sitting in a wheelchair or the like. The present invention relates to a belt-type sitting position holder that can prevent collapse of the body and can flexibly cope with seated persons of different body shapes.
周知のとおり、自ら立って歩くことのできない下半身が不自由な被介護者を移動させる際には、車椅子等を利用するのが一般的であるが、被介護者を乗せた状態で車椅子を動かすと走行中の振動や停止時の慣性力によって、被介護者の着座位置が前方にズレて着座姿勢が崩れたり、車椅子から転落したりする問題が生じる。 As is well known, when moving a cared person who is unable to stand and walk on the lower body, it is common to use a wheelchair, etc., but move the wheelchair with the cared person on board. Due to vibration during running and inertial force at the time of stopping, there arises a problem that the sitting position of the cared person is shifted forward and the seating posture is lost or falls from the wheelchair.
そこで、従来においては、車椅子に装着できるＨ型またはＴ型の股ベルトも開発されているが(例えば、特許文献１参照)、これら従来の股ベルトは、被介護者の着座位置を前方にズラす負荷がかかった際に、中央のベルトによって被介護者の股間が圧迫される構造であったため、座り心地を損なう原因となっていた。 Therefore, conventionally, an H-shaped or T-shaped crotch belt that can be mounted on a wheelchair has been developed (see, for example, Patent Document 1). When a heavy load is applied, the caregiver's crotch is pressed by the belt at the center, which causes a loss of sitting comfort.
一方、従来においては、大腿部に巻き付ける脚拘束帯を有するハーネス型のチャイルドシートも開発されているが(特許文献２参照)、この技術に関しては、ハーネスをシートベルトに装着して着座位置を固定する構造であったため、シートベルトを持たない車両シート以外の車椅子等には利用することができなかった。 On the other hand, although a harness-type child seat having a leg restraining band wound around the thigh has been developed in the past (see Patent Document 2), the seat is fixed by attaching the harness to the seat belt. Therefore, it could not be used for wheelchairs other than vehicle seats without a seat belt.
また、上記ハーネス型の座位保持具に関しては、着座者の腰部の支持が充分に行われていなかったため、着座中に骨盤が後傾して被介護者の着座姿勢が崩れる問題もあった。加えて、腰部のサポートが不充分になることで着座時の腰部の負担が増大し、長時間の着座によって被介護者に腰痛が生じる問題もあった。 Further, the harness-type sitting position holder has not been sufficiently supported by the seated person's waist, so that there is also a problem that the seated position of the cared person is lost due to the pelvis tilting backward while seated. In addition, insufficient support for the lower back increases the burden on the lower back when seated, and there is also a problem that back pain occurs in the cared person due to prolonged sitting.
他方、従来においては、被介護者の腰部に巻く骨盤ベルトを備え、かつ、骨盤ベルトと背凭れ部とを面ファスナで固定できるようにした座位保持具も公知となっているが(特許文献３参照)、この技術では、骨盤ベルトの位置を調節できなかったため、着座者の体型に応じて個別に座位保持具を作製する必要があった。 On the other hand, conventionally, a sitting position holding tool that includes a pelvic belt wound around the waist of a cared person and that can fix the pelvic belt and the backrest portion with a hook-and-loop fastener is also known (Patent Document 3). In this technique, since the position of the pelvic belt could not be adjusted, it was necessary to individually prepare the sitting position holder according to the body shape of the seated person.
また、上記骨盤ベルト式の座位保持具に関しては、下肢の固定が行われていなかったため、被介護者を車椅子に載せて移動する際に下肢が内外方向にふらつく問題があった。しかも、上記座位保持具を使用する際には、背凭れ部の所定位置に面ファスナの取付け加工を行った椅子をわざわざ用意する必要があった。 Further, the pelvic belt-type sitting position retainer has not been fixed to the lower limbs, and thus has a problem that the lower limbs fluctuate inward and outward when the care recipient is moved on a wheelchair. In addition, when using the above-mentioned sitting position holder, it is necessary to bother preparing a chair in which a hook-and-loop fastener is attached at a predetermined position of the backrest.
本発明は、上記の如き問題に鑑みて為されたものであり、その目的とするところは、車椅子等に座った着座者に不快感が生じない状態で着座位置を固定することができ、また、着座者の下肢のふらつきや着座姿勢の崩れも防止でき、しかも、体型の異なる着座者に対しても柔軟に対応可能で椅子の背凭れ部に特別な加工を行う必要もないベルト式座位保持具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 fix the seating position in a state in which the seated person sitting in the wheelchair does not feel uncomfortable, Belt-type sitting position that can prevent wobbling of the lower limbs of the seated person and collapse of the sitting position, and can be flexibly adapted to seated persons of different body shapes, and does not require special processing on the backrest of the chair It is in providing tools.
