A Wheelchair Design for Topple Prevention

Abstract:

Wheelchairs are an indispensable transportation tool for the aged and for the disabled. Tips and falls are common accidents to current wheelchairs, suggesting wheelchair safety is imperfect. This study thus proposed an anti-tip concept design to improve manual wheelchair safety. The anti-tip wheelchair was ergonomically designed with the following features: (1) diamond pattern wheel alignment enables users to adjust rear-wheel chamber angle and extend the front and rear casters forward and backward respectively to prevent tipping by increasing the base area; (2) adjustable wheel mechanism for indoor and outdoor uses; (3) collinear alignment of the rear-wheel axle and the center of mass in the sagittal plane reduces push frequency and enhances push power; (4) a spring-driven rear caster compression mechanism aids passing over obstacles on the ground; and (5) height adjustable neck rest provides comfort support.
