The Safer Automatic Wheelchair Wheel Locks/Brakes are controlled by weight on the seat of the wheelchair. When the chair is occupied-weight on the seat-the locks are not engaged and the user may roll about as he wishes. When the weight is lifted from the seat-the person gets up-the locks/brakes "automatically" engage, locking the wheels until the weight is applied again.

When the person lifts his weight from the wheelchair seat, spring-activated levers rise and shift fixed gear blocks into contact with gear hubs mounted on each wheel. The teeth on these blocks and hubs mesh to prevent the wheels from moving. It's that simple. Yet, this device is highly effective in preventing falls and injury.

Overrides mounted on the handles of the wheelchair disengage the locks/brakes in order to allow attendants to move an empty chair easily.

The automatic wheelchair locks/brakes do not interfere with folding the wheelchair for storing or transporting.
