Abstract

A tracked powered chair is described. A side drive assembly comprises a powered sprocket, a forward non-powered two wheel bogey, and a rearward non-powered two wheel bogey. Each bogey has a respective pivot member pivotally fastened at a first pivot member end between the first and second bogey wheels, and a second pivot member end fastened to the frame such that the forward and rearward bogey each pivot independently from one another around its respective pivot member. The geometry of the drive assembly creates a non-isosceles shaped triangular appearance (no two sides are of equal length).
