  • Rollator having a sit-to-lock brake
    Patent number: 8840124
    Abstract: A safety brake type rollator that will prevent the misuse of rollators by seated users by using a braking system that locks the rollator wheels when the user sits down on the rollator seat, and releases when the user stands up. The cables that run from the hand brakes of the rollator to under the rollator seat are stretched by the user sitting down on the rollator seat, so locking the wheels. According to a further embodiment, whenever a user sits on the seat the braking system pulls the hand brakes into the locked position, so engaging the wheel brake mechanisms. According to this further embodiment, the hand brakes must then be disengaged from the locked position when the user stands up from the seat for the rollator to be mobile.
