手动轮椅 - NSL903LQ

一个自旋转的手动轮椅包含一个框架，座椅，一个或两个脚踏板（脚凳）和四个轮子：通常在前面有两个施法轮，背面有两个大轮子。通常还会有一个单独的座垫。较大的后轮通常在轮胎以外的直径略小的推动边缘。这些使用户可以通过向椅子推开椅子而无需抓住轮胎来制定椅子。手动轮椅通常在后轮轮胎上有刹车，但是这些仅是驻车制动器，并且用户的手掌直接在推杆上放置了动力制动器。由于这会导致摩擦和热量堆积，尤其是在长途滑坡上，因此许多轮椅使用者会选择戴上带衬垫的轮椅手套。手动轮椅通常在框架的上部有两个推动手柄，以允许第二人手进行手动推进，但是许多活跃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。

每天手动轮椅进来两个主要变化eties, 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. Welded rather than folding joints also reduce the overall weight of the chair. Rigid chairs typically feature instant-release rear wheels and backrests that fold down flat, allowing the user to dismantle the chair quickly for storage in a car. A few wheelchairs attempt to combine the features of both designs by providing a fold-to-rigid mechanism in which the joints are mechanically locked when the wheelchair is in use.
