Abstract

The present invention is a wheelchair control sensor for controlling a powered wheelchair for spinal cord-injured persons, who are incapable of using their hands, using movement of shoulders. The wheelchair control sensor includes two shoulder straps, two casings, two Force Sensitive Resistor (FSR) sensors, pressing balls, and a waist belt. The casings each have an internal space defined by an inclined surface. The FSR sensors are attached to the inclined surfaces of the casings or surfaces opposite to the inclined surfaces. The pressing balls are connected to the shoulder straps to press the FRS sensors while being moved through the internal spaces of the casings by external force. The waist belt is worn on an upper garment with the two casings spaced apart from each other at a certain interval.

Description

technical field [0001] The invention relates to a wheelchair control sensor used by people whose hands cannot move, in particular to a wheelchair control sensor used by people with spinal disabilities to control electric wheelchairs by using shoulder activities. In addition, the invention also relates to a device for controlling the activities of the wheelchair by using the wheelchair control sensor. technical background [0002] Most people with spinal disabilities who cannot move their hands cannot ride a wheelchair and need help from others to use it. Furthermore, it is difficult to obtain a wheelchair device with controls suitable for persons with spinal disabilities. Currently, there are few wheelchairs on the market suitable for people with spinal disabilities who cannot move their hands. [0003] In order to facilitate the use of people who cannot move their hands, a wheelchair has appeared, which is controlled by a contact or non-contact switch installed on the hea...
