Abstract: A caster-wheel assembly (100; 200) for a vehicle, for example a wheelchair or powered wheelchair. The caster-wheel assembly comprises a switch (13) coupled to a housing (3); a castering wheel bracket (9) configured to receive a wheel (10), wherein the bracket is rotatably mounted about a caster pivot axis (28) with respect to the housing; biasing means (15) configured to provide a biasing force such that the wheel bracket is biased away from the housing; and a switch-actuating member (13) coupled to the wheel bracket such that movement of the wheel bracket towards the housing and against the biasing force causes the switch-actuating member to actuate the switch.

Abstract: A brake system for use with a wheeled device, such as a wheeled person transportation device, such as a wheelchair. The brake system comprises a handle comprising a first portion and a second portion, wherein the first portion is moveably coupled to the second portion; a carrier comprising an internal cavity; a brake actuator for actuating a brake, the brake actuator being arranged within the internal cavity; brake actuator biasing means for applying a biasing force to the brake actuator for biasing the brake actuator to a brake-engaged position; and force-transfer means coupled to the first portion and to the brake actuator such that movement of the first portion towards the second portion causes the brake actuator to move along the internal cavity of the carrier against the biasing force to a brake-disengaged position.
