Abstract
A safety airbag device for cushioning the free fall of a person or object from an elevated height. The airbag device includes an inflatable base bag capable of sustaining an air pressure and an inflatable structure coupled to the base bag, where the inflatable structure is in air communication with the base bag. A net is coupled to a top portion of the inflatable structure for decelerating and supporting the individual from free fall. A top cover is coupled to the base bag that substantially encloses the inflatable structure.
Claims27
An airbag device to cushion the free fall of a subject from an elevated height comprising:
- an inflatable base bag capable of sustaining an air pressure;
- an inflatable structure comprised of a plurality of individual inflatable members, each comprising:
- a wall with an annular cross-section;
- a top first end that is closed;
- and
- a second end opposite the first end,
- wherein the second end is coupled to an exterior upper surface of the base bag and is in fluid communication with the base bag,
- wherein a space is located between each of the individual inflatable members and the other inflatable members such that the individual inflatable members do not touch and are not in direct fluid communication with the other individual inflatable members;
- a net directly attached by net fasteners to a top portion of the inflatable structure, the net comprising:
- a first set of frame members;
- a second set of frame members oriented transverse to the first set of frame members;
- and
- wherein the first set of frame members are coupled to the second set of frame members by a plurality of knots and form a lattice having a plurality of open cells adapted to decelerate and support the subject from free fall;
- and
- a top cover attached indirectly to the base bag, the top cover having a top sheet and side sheets that substantially cover and enclose the inflatable structure, while not being directly attached by fasteners to the net or the inflatable structure.

A safety system for cushioning the free fall of a subject from an elevated height comprising:
- an inflatable base bag capable of sustaining an air pressure;
- an inflatable structure coupled to the base bag, the inflatable structure comprised of a plurality of elongate individual inflatable members, each comprising:
- an annular wall;
- a closed top end;
- and
- an open end that is coupled to a top wall of the base bag,
- wherein each individual inflatable member is spaced apart and does not touch from the other inflatable members and is in individual fluid communication with the base bag such that each of the individual inflatable members is not in direct fluid communication with the other inflatable members;
- a net connected to atop portion of the inflatable structure, the net comprising:
- a first set of frame members;
- a second set of frame members oriented transverse to the first set of frame members, wherein the first set of frame members are directly attached to the second set of frame members by a plurality of knots and form a lattice having a plurality of open cells adapted to decelerate and support the subject from free fall;
- and
- a top cover located over the net and attached directly to the base bag by at least one retaining member, the top cover having a top sheet and side sheets that substantially cover and enclose the net and inflatable structure, while not being directly attached by fasteners to the net or the inflatable structure.

An airbag safety system to cushion the free fall of a subject from a height comprising:
- an inflatable base bag capable of sustaining an air pressure;
- a plurality of elongate crumple tubes, each individually comprising:
- an annular wall;
- a closed top end;
- and
- an open end that is coupled to a top wall of the base bag,
- wherein each of the plurality of crumple tubes is individually in fluid communication with the base bag through the open end and each of the individual crumple tubes is spaced apart such that the individual crumple tubes are not in direct fluid communication with the other individual crumple tubes;
- a plurality of fasteners affixed to the closed top end of a plurality of the elongate crumple tubes;
- a net, attached to the elongate crumple tubes by the fasteners, comprising:
- a first set of frame members;
- a second set of frame members oriented transverse to the first set of frame members;
- and
- wherein the first set of frame members are coupled to the second set of frame members by a plurality of knots and form a lattice having a plurality of open cells;
- and
- a top cover attached indirectly to the base bag, the top cover having a top sheet and side sheets that substantially cover and enclose the inflatable structure, while not being directly attached by fasteners to the net or the inflatable structure.
