  • Patent number: 5499856
    Abstract: A foldable front-entry safety walker is disclosed having a resistance to backward motion of the walker. Various embodiments of the walker are disclosed. The walker includes a pair of side frames, along with a corresponding pair of front legs and a pair of rear legs. A foldable seat is disposed at the rear portion of the walker. The walker is relatively lightweight allowing a person with limited walking ability to easily advance the walker forward. The rear legs may have spring-loaded brakes that are functional to prevent backward motion of the walker under certain conditions. If the user falls backward for whatever reason, the user will strike either the seat back or the seat cushion and the force of the falling body will activate a spring-loaded rear legs to prevent backward motion of the walker.
