Manual Wheel Chair – NSL903LQ

A self-propelled Manual Wheel Chair 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. As this causes friction and heat build-up, particularly on long downslopes, many wheelchair users will choose to wear padded wheelchair gloves. Manual wheelchairs often have two push handles at the upper rear of the frame to allow for manual propulsion by a second person, however many active wheelchair users will remove these to prevent unwanted pushing from people who believe they are being helpful.

日常手动轮椅有两种主要品种，折叠或刚性。折叠椅通常是低端设计，其主要优点在于能够折叠，通常通过使双面成为在一起。然而，这在很大程度上是可能需要更频繁地存储轮椅的兼职用户的优势。刚性轮椅越来越优选的全职和活跃的用户越来越优选，具有永久焊接接头和多种移动部件。这减少了通过消除椅子弯曲和吸收能量的许多点来推动椅子所需的能量。焊接而不是折叠接头也降低了椅子的总重量。刚性椅子通常具有即时释放的后轮和靠背折叠平面的靠背，允许用户快速拆除椅子以存放在汽车中。几个轮椅尝试通过提供折叠刚性机构来结合两种设计的特征，其中当轮椅使用时，接头在机械上锁定。
