A safety walker provides a strap that actuates to allow a person to enter into the safety walker and then raise the strap between their legs. The strap prevents ground level falls. The safety strap is actuated by a strap actuator that may pivot about a pivot attached to the movable support frame. The strap actuator may be locked into a secure position with the strap in an elevated position by a latch. The strap actuator may be coupled to a handle actuator by one or more linkages, or the strap actuator and handle actuator may be a one-piece rigid member that rotates about a single pivot on the moveable frame. A coupling member may extend between a left and right strap actuator proximal to the back end of the strap actuators and the safety strap may be attached to the coupling member.
