(6) Since the connection hole of the connection support portion is formed to be inclined so that the front is high and the rear is low, the inclined thigh can be reliably supported by the entire width of the first support member. Excellent thigh support stability.

ここで、第一支持具の材質としては、ポリアミド、ＡＢＳ、ポリカーボネート、ポリアセタール、ポリフェニレンエーテル、ポリブチレンテレフタレートなどのエンジニアリングプラスチック等が好適に用いられる。
固着部の形状は、着座部の側部フレームの形状等に応じて、適宜、選択することができる。尚、固着部は側部フレームに直接、取り付けてもよいし、側部フレームに装着される別部材を介して取り付けてもよい。また、固着部の固定方法は、適宜、選択することができるが、着脱容易性、固定確実性に優れる螺子止めが好適に用いられる。
尚、第一支持部材としては、ポリプロピレン製やポリエステル製などの織物繊維でベルト状に形成されたものが好適に用いられる。第一支持部材の長さや張り具合を調整することにより、適度な弾力性で使用者の大腿部を所定の角度に支持することができ、保持安定性に優れる。 Here, as the material for the first support, engineering plastics such as polyamide, ABS, polycarbonate, polyacetal, polyphenylene ether, polybutylene terephthalate, and the like are preferably used.
The shape of the fixing portion can be appropriately selected according to the shape of the side frame of the seating portion. The fixing portion may be directly attached to the side frame or may be attached via a separate member attached to the side frame. In addition, the fixing method of the fixing portion can be selected as appropriate, but screw fixing that is excellent in detachability and fixing reliability is preferably used.
In addition, as a 1st supporting member, what was formed in belt shape with the textile fiber made from a product made from a polypropylene, polyester, etc. is used suitably.
