  • Wheel chair electric brake and pedal safety kit
    Patent number: 5358266
    Abstract: A conventional wheel chair is modified by the provision of a safety system for automatically actuating the brakes of the wheel chair and lifting the foot rests when the weight of the patient is lifted from the seat. An overcenter spring arrangement is used to bias the brake mechanism into the braking position and is pulled over center by a solenoid actuated by a switch under the seat. The actuation of the brake mechanism is communicated to the foot pedals by a connection cable which pulls a latch pin to release the spring biased foot pedal into the retracted position.
