Abstract
This paper presents a method to integrate anthropometry to Davies' method, which is then used for the dimensional synthesis of a backrest mechanism of a hospital bed. Using Davies' method to solve both kinematic and static models while employing a differential evolution algorithm, the lengths of the links of the mechanism and the actuation force of new mechanism for the backrest mechanism are optimized. The optimization used anthropometric parameters as the primary variables when solving Davies' method. The lengths of the links are optimized seeking smaller actuation forces. The new mechanism is presented along with the forces required to actuate it during the range of movement.
