Abstract
Nowadays, apparatus for berthing wheelchairs are configured in many vehicles for public transportation and welfare purpose. Many problems have also been found from practical usage of them. For example, they can not work well with all the wheelchairs of various sizes. Due to the improper fixing position, they are not stable enough confronted to transverse shake. Especially, for most of them, it is impossible to fasten and unfasten the apparatus by the disabled people themselves. In this research, a new kind of wheelchair with a built-in berthing apparatus is proposed. It is expected able to solve the above problems. The usage of this wheelchair only requires a common mooring unit configured in a vehicle. This makes it easy to standardize this kind of berthing apparatus.
