Embodiment Construction

[0048] Such as figure 1 As shown in FIG. 6 , the wheelchair of the present invention includes a support chassis 1 on which a seat structure 2 is installed. According to the form shown, the chassis 1 comprises two motor-driven front wheels 3 , each supported by an outrigger 4 . Chassis 1 also comprises two so-called free-moving rear wheels 5 connected to chassis 1 by pivots 6 lying on approximately vertical axes.

[0049] In order to allow the wheelchair to change direction when it changes position, each drive wheel 3 is equipped with a geared electric motor 7 powered by a set of batteries 8 and controlled by a control unit 9 mounted with a joystick 10 control. Using the joystick 10, the control unit 9 is used to control the motor-driven wheels 4 in synchronous or asynchronous operation, so as to move the wheelchair of the present invention forward, backward, left, or right.

[0050] Naturally, it needs to be understood that this method of realizing the support chassis 1 is ...
