#$%^&*AU2015249084A120151112.pdf#####A powered mobility device or wheel chair (10) is disclosed that is able to be steered with or without the use of hands. The device includes at least two drive wheels (12, 13), a drive controller, a tiltable seat (11) mounted to a tilt mechanism able to tilt the seat in forward, backward, left and right directions as a result of the user shifting their body weight and a weight sensor. The tilt mechanism includes at least primary and secondary pivots, where the primary pivot is mounted to a shaft so as to allow the tilt mechanism to tilt the seat in a forward and backward direction. The secondary pivot is spaced a distance above the primary pivot so that the secondary pivot is situated between the seat and the shaft such that the secondary pivot allows the seat to tilt back or forward about the secondary pivot so as to enhance the offset of weight transfer so as to cause increased control of the back or forward tilt of the seat relative to the shaft. Upon sensing a weight displacement of a user in a particular direction the weight displacement sensors causes the drive control means to impart drive to the drive wheels to move the mobility device in the sensed direction. A hand controller is selectively engageable with the tilt mechanism and the weight displacement sensor so that the hand controller can disengage left and right movement of the tilt mechanism. The hand controller (14) causes the weight sensor to cause the drive control means to steer the mobility device in a desired direction instead of the tilt mechanism. The hand controller (14) may provide more sensitive steering.Sheet I of 7 ............. ...... ...... .......................... .................. ................ .......... ............................ ...... ............................................................................. ......... ............... ......................... ....... ....... ......................................................
