Abstract

The motorized rolling armchair comprises a motor-transmission assembly (1,2) the output shaft of which (3) extends on either side of the transmission gear (1) and carries at each of its ends a rolling train (4,5). The motor-transmission assembly (1,2) carries a support (6) on which are fastened batteries (7) and which is provided at its front lower end with at least a roller (8). It comprises a light casing (9) on which the seat (10) and the back (11) of the armchair, of synthetic plastic material, are directly injected. Rapid corrections (14,20) are provided to couple and uncouple the casing to the motor-transmission assembly (1,2).

Claims
