An epileptic mother wanted a self-acting brake that would automatically immobilise a pushchair if the mother had a fit. A brake lever was connected to the brake via a Bowden cable. To release the brake, the client places her wrist under the rod and plastic ball and, by squeezing the brake lever, a small latch falls into place to hold the lever closed. The lever remains closed whilst the wrist is lifting the ball, if the hand is removed the ball falls, releasing the latch which applies the brake. The mother has peace of mind that her child will not come to harm if the mother has a fit whilst in control of the wheelchair.
