摘要： The present invention provides portable safety cushion apparatus for use below a workplace for arresting the fall of an object. It comprises a cushion having upper (11) and side faces (13) and a generally planar lower face (12) that is positioned on a surface. The upper, lower and side faces are formed from a lightweight flexible material and together define a single inflatable chamber (14). One or more face is provided with a plurality of apertures (18) that allow the controlled escape of air from the chamber. The apparatus also comprises an air pump (16) that continuously pumps air into the cushion to inflate it. In normal use when inflated the rate of air inflow from the pump is equal to the rate of outflow of air through the apertures, but when an object (20) falls upon the cushion the rate of air flow through the apertures increases such that the cushion deflates and slows the descent of the object to lower it to the surface without causing more than minimal rebound. The present invention also relates to a method of decelerating a falling object.
