Abstract
An airbag landing device for absorbing an impact of a falling object is disclosed. The airbag landing device includes an inflatable base structure with at least one inflatable closed-cell chamber configured to hold a first fill volume of gas and an inflatable top structure disposed vertically on top of the inflatable base structure. The inflatable top structure includes a central, external chamber, and at least one inflatable open-cell chamber that is configured to sustain a second fill volume of gas. The airbag landing device includes a top cover over the inflatable top structure. The top cover overlays the central chamber to form an air pocket therebetween. At impact, the inflatable top structure exhausts a volume of gas from the air pocket and from the open-cell chamber of the inflatable top structure while the first fill volume of the at least one inflatable closed-cell chamber is maintained.
