Abstract

本物品は、クッション中材で座面クッションもしくは背面クッションとしてそれぞれ設置して使用するもので、座面と背面に2枚同時に設置して使用することもできるものである。クッションを配置する椅子は背もたれのある椅子や車椅子、車のシートなどであり、座面と背面にかかる体重を分散できる効果を得られる特長を有するクッション中材である。 参考平面図1に示すように、クッション中材の素材は、ウレタンや低反発ウレタン、ポリエステルおよびポリエステルエステール系繊維、スポンジ、ビーズなど成型できるもので硬め(硬質)の素材と柔らかめ(軟質)の素材を組み合わせで構成され接着剤などの溶剤で接着、または熱などで融着されている。クッション中材の形状はクッション中材の前方と両側面は硬め(硬質)の素材で形成され、クッションを平面視で見てコの字状に構成されている。 参考斜視図1、参考写真1、参考写真2に示すように、座面として使用する際は、硬め(硬質)の素材側を座面の前部に配置し柔らかめ(軟質)の素材側を後部に配置することにより、クッション中材の凹部の前方と両横の硬め(硬質)の素材が膝から大腿部、臀部を支え、同時に凹部内側の柔らかめ(軟質)の素材部分は、着座時に座骨および仙骨があたる部分を優しく支える。着座した状態のときに硬め(硬質)の素材により体重を支える比重が高くなり、柔らかめ(軟質)の素材部分にかかる圧力を低減して座骨および仙骨にかかる圧力の負担を軽減する。 参考斜視図2、参考斜視図4、参考斜視図5、参考写真3に示すように、背面として使用する際は、クッション中材の硬め(硬質)の素材側を背面の下部に、柔らかめ(軟質)の素材側を背面の上部に配置することにより、硬い層で骨盤を支え背筋を伸ばした姿勢を支持し易くなる。 参考斜視図3、参考斜視図6、参考斜視図7、参考写真4に示すように、凹に挟まれた柔かい部分を下に配置すると骨盤が後傾している円背や猫背の方の臀部を優しく支える構造的効果を得られる。このように、クッション中材を座面のみもしくは背面のみに使用する態様とクッション中材を座面と背面の両方に使用し背面のクッション中材の配置上下で変えることにより、素材の硬軟が異なり体圧を分散し、使用者は座り心地を確認して自分の態勢に合わせて自由に配置を選択することができる。 参考斜視図4、参考斜視図5、参考斜視図6、参考斜視図7、参考写真5、参考写真6、参考写真7に示すように、クッション中材を座面と背面に同時に2枚配置することにより、体圧分散と姿勢調節を効果的に行うことができ、座位姿勢の保持と長時間使用時の臀部や腰、背中などへの負担を軽減し、より安楽で心地よい姿勢を保持することで腰痛防止効果を高める。 クッションの前後または上下を確認するためには視認または触れて認識する必要があるが、一般的にクッションの形状は四角状や丸状のものが多く、視覚障害のある方にとっては形状の違いで情報を伝える必要が生じる。そこで、参考平面図1に示すように、本クッションの形状を一般的な4角状から中央後部の柔かめ(軟質)の素材側の角に切り欠きを入れることによりクッション中材の前後と上下を触れて認識をできるようにするものである。この場合切り欠き部分は、クッション中材の向きを座面でも背面でも容易に認識して配置することを可能にするものであり、高齢者や視覚障害者にも容易に使用することができる形状にしたものである。さらに参考写真3、参考写真4、参考写真5、参考写真8に示すように、車椅子にクッション中材を座面や背面に配置して使用する場合、一般的な車椅子の構造が各メーカーによって座面形状や座幅、奥行きが異なる。大人用車椅子の既製品サイズは、シート幅380mmから420mmで、体の大きい方向けに450mmサイズなどもあるが、不特定多数の方が使用する病院や施設の車椅子は400mmが多く使用されている。座面奥行は、使用する方の座低長により異なるが400mmの車椅子が多い。しかし子供から大人まで使用することを想定した場合、座面幅は320mmから450mm、座面の奥行は320mmから420mmを想定する必要がある。車椅子の材料と構造は、一般的にアルミやスチール等のパイプの材料で構成されており、座面のサイドフレームパイプと背もたれのバックサポートパイプを溶接等により成形し、座面シートフレームにクッションを載せて座る形状となっている。これらの構成で座と背のフレームの構造を成型しているが、既存の座面シートに本クッションを設置する場合、車椅子の座面後部のバックサポートのフレームがクッション後方の両サイドに当たり、座面の奥に押し込めない状況が生じる。 そこで参考平面図1に示すように、本クッション中材後部2辺の角に切り欠きを形成することにより、座面シートの奥まで配置できるようになり、より多くの車椅子ユーザーの身体に合わせて設置できるようになる。 座面と背面の配置方法として、参考斜視図4、参考斜視図5、参考斜視図6、参考斜視図7、参考写真5、参考写真6、参考写真7に示すように、クッション中材を使用する椅子や車椅子、車のシートなど対象とする椅子に配置する場合、椅子の座面にクッション中材を敷きその上かつ背面にクッション中材を載せるように配置する方法と、クッション中材を背面に配置して、その前側かつ椅子の座面にクッション中材を敷く方法がある。対象とする椅子の奥行きの長さや座る方の座低長に合わせて調整することができる本申請の形状の違いにより、高齢者や視覚障害者などが座面前後や背面の上下を容易に判別できる。 また、参考写真2に示すように、車や家具椅子など椅子によっては背面側のシート形状がバケット状で湾曲した椅子もあるが、座面として本クッション中材を設置した際に後部の切り欠きがあることにより、座面後部が背もたれ側の湾曲に沿いやすくなり座面奥に配置しやすくなる。This article is used by setting it as a seat surface cushion or a back cushion with a cushion middle material, and can also be used by setting two sheets on the seat surface and the back surface at the same time. The chair on which the cushion is placed is a chair with a backrest, a wheelchair, a car seat, or the like, and the cushion medium has the feature of distributing the weight applied to the seat surface and the back surface. As shown in the reference plan view 1, the materials for the cushion middle material are urethane, low-resilience urethane, polyester and polyester ester fibers, sponge, beads, etc., which can be molded. It is composed of a combination of materials and is adhered with a solvent such as an adhesive or fused with heat. As for the shape of the cushion middle material, the front and both side surfaces of the cushion middle material are formed of a harder (hard) material, and the cushion is configured in a U shape when viewed from above. As shown in reference perspective view 1, reference photo 1, and reference photo 2, when using as a seat surface, place the hard (hard) material side in front of the seat surface and place the soft (soft) material side. By placing it in the rear, the hard (hard) material on the front and both sides of the concave part of the cushion middle material supports the knees, thighs, and buttocks, and at the same time, the soft (soft) material part inside the concave part is used to support the seat. Gently support the area where the sit bones and sacrum sometimes touch. When you are seated, the harder (hard) material increases the specific gravity that supports your weight, and the pressure applied to the softer (softer) material is reduced to reduce the burden of pressure on the ischium and sacrum. As shown in Reference Perspective View 2, Reference Perspective View 4, Reference Perspective View 5, and Reference Photo 3, when using as a back surface, place the harder (hard) material side of the cushion middle material at the bottom of the back surface, and the softer ( By arranging the soft layer on the upper part of the back, the hard layer supports the pelvis and makes it easier to support the posture in which the back muscles are stretched. As shown in reference perspective view 3, reference perspective view 6, reference perspective view 7, and reference photo 4, when the soft part sandwiched between the concaves is placed downward, the pelvis is tilted backward. You can get a structural effect that gently supports the In this way, the hardness and softness of the material differ depending on whether the cushion material is used only on the seat surface or only on the back surface, or by using the cushion material on both the seat surface and the back surface and changing the arrangement of the cushion material on the back surface. By distributing the body pressure, the user can check the comfort of sitting and freely select the placement according to his posture. As shown in reference perspective view 4, reference perspective view 5, reference perspective view 6, reference perspective view 7, reference photo 5, reference photo 6, and reference photo 7, two pieces of cushioning material are placed on the seat surface and the back at the same time. As a result, it is possible to effectively disperse body pressure and adjust posture, maintain a sitting posture, reduce the burden on the buttocks, waist, back, etc. during long-term use, and maintain a more comfortable and comfortable posture. to enhance the effect of preventing back pain. In order to check the front and back or top and bottom of the cushion, it is necessary to recognize it visually or by touch, but in general, most cushions are square or round, and the shape is different for people with visual impairments. Information needs to be conveyed. Therefore, as shown in the reference plan view 1, the shape of this cushion is changed from a general quadrangular shape to a notch in the corner of the soft (soft) material side in the central rear part, so that the front and back and top and bottom of the cushion middle material can be adjusted. It is something that allows you to recognize by touch. In this case, the cut-out part makes it possible to easily recognize the direction of the cushion material on the seat surface and the back surface and arrange it, making it easy to use even for the elderly and visually impaired. It is the one that was made. Furthermore, as shown in Reference Photo 3, Reference Photo 4, Reference Photo 5, and Reference Photo 8, when using a wheelchair with cushioning materials placed on the seat surface and back, the structure of a general wheelchair varies depending on the manufacturer. The surface shape, seat width and depth are different. Ready-made adult wheelchairs have a seat width of 380mm to 420mm, and although there are 450mm sizes for larger people, 400mm wheelchairs are often used in hospitals and facilities where an unspecified number of people use them. . The seat depth varies depending on the seat height of the user, but most wheelchairs have a depth of 400 mm. However, when assuming use by children and adults, it is necessary to assume a seat width of 320 mm to 450 mm and a seat depth of 320 mm to 420 mm. The materials and structures of wheelchairs are generally composed of pipe materials such as aluminum and steel. The side frame pipes of the seat and the back support pipe of the backrest are formed by welding, etc., and the cushion is attached to the seat frame. It has a shape that allows you to sit on it. The structure of the seat and back frame is molded with these configurations, but when installing this cushion on an existing seat, the frame of the back support at the rear of the seat of the wheelchair hits both sides behind the cushion, A situation arises in which it is not possible to push the object into the depth of the surface. Therefore, as shown in the reference plan view 1, by forming notches in the two rear corners of the middle material of this cushion, it becomes possible to arrange it all the way to the back of the seat. be able to install. As shown in Reference Perspective View 4, Reference Perspective View 5, Reference Perspective View 6, Reference Perspective View 7, Reference Photo 5, Reference Photo 6, and Reference Photo 7, use cushioning materials for the placement of the seat and back. When arranging on the target chair such as a chair, wheelchair, car seat, etc., a method of placing the cushion material on the seat surface of the chair and placing the cushion material on the back and placing the cushion material on the back There is a method of arranging it on the front side and laying a cushioning material on the seat surface of the chair. The difference in the shape of this application, which can be adjusted according to the depth of the target chair and the low seat length of the person sitting, makes it easy for the elderly and visually impaired to distinguish between the front and back of the seat and the top and bottom of the back. can. In addition, as shown in Reference Photo 2, some chairs, such as cars and furniture chairs, have bucket-shaped seats on the back side and are curved. With the presence of this, the rear part of the seat surface can easily follow the curve on the backrest side and can be easily placed at the back of the seat surface.
