Abstract: An inflatable portable refuge structure includes at least one refuge chamber having a floor, ceiling and a peripheral sidewall and an inner resealable entrance in the peripheral sidewall of the refuge chamber. An airlock chamber having a floor, ceiling and peripheral sidewall is connected to the refuge chamber adjacent the inner resealable entrance such that exiting from the refuge chamber through the inner resealable opening proceeds into the airlock chamber. The airlock chamber further includes an outer resealable entrance in the peripheral sidewall thereof. The refuge chamber and airlock chamber each further include at least one one-way pressure valve, the pressure valves operative to release air from within the chambers in response to increased air pressure within the chambers. An external pressurized air supply source spaced from the refuge structure and connected thereto by an air supply hose supplies uncontaminated air to the refuge chamber thereby inflating the refuge structure.

Abstract: A baby swing seat having a generally horizontal seating member with top and bottom surfaces, a generally upright back support and two arm rest support members. The detachable leg extension is adapted to be placed adjacent the seating member top surface and adapted to extend generally horizontally and forwardly of the seating member, thereby supporting the legs of a baby seated in the swing seat. The seat may also be configured with a cross-member extending between the support arms to provide additional positioning support. Additionally, the rearward end of the seat may be of increased thickness to provide additional support.
