    轮椅A self-propelled manual wheelchair incorporates a frame, seat, one or two footplates (footrests) and four wheels: usually two caster wheels at the front and two large wheels at the back. There will generally also be a separate seat cushion. The larger rear wheels usually have push-rims of slightly smaller diameter projecting just beyond the tyre; these allow the user to manouevre the chair by pushing on them without requiring them to grasp the tyres. Manual wheelchairs generally have brakes that bear on the tyres of the rear wheels, however these are solely a parking brake and in-motion braking is provided by the user’s palms bearing directly on the push-rims.

    由于这会导致摩擦和热量积聚,尤其是在长下坡路上,因此许多轮椅使用者会选择穿衬垫轮椅。手动轮椅通常在框架的上部有两个推动手柄,以允许第二个人手动推进,但是许多主动的轮椅使用者会删除这些手动推动,以防止从相信自己有帮助的人的不必要的推动力。

    Everyday manual Wheel Chair come in two major varieties, folding or rigid. Folding chairs are generally low-end designs, whose predominant advantage is being able to fold, generally by bringing the two sides together. However this is largely an advantage for part-time users who may need to store the wheelchair more often than use it. Rigid wheelchairs, which are increasingly preferred by full-time and active users, have permanently welded joints and many fewer moving parts. This reduces the energy required to push the chair by eliminating many points where the chair would flex and absorb energy as it moves.

    焊接而不是折叠接头也减少了椅子的整体重量。刚性椅子通常具有即时释放的后轮和靠背折叠的靠背,使用户可以快速拆除椅子以存放在汽车中。几支轮椅试图通过提供折叠到刚性的机制来结合两种设计的特征,在使用轮椅时,接头被机械锁定。
