Seat posture stabilizing function for an electric wheelchair based on controlled pendulum mechanism

The purpose of this study is to develop a seat posture stabilizing function for an electric wheelchair without actuators. The non-actuator seat posture stabilizing function uses instruments that can stabilize the posture of a passenger seat, including controlled pendulum mechanism, brake, and posture angle detector. When applying the novel seat posture stabilizing function to personal mobility means, we found that the seat posture stabilizer could maintain the stability of seat against 15° of both uphill and downhill slopes. In addition, for the implementation of the non-actuator seat posture stabilizing function, we plan to suggest a design guideline for installation on a hinge position using Nx dynamic motion S/W.
