Abstract
Abstract A manipulable device for piercing a cartridge releases gas under pressure into conduits to release all the buckles of the harness. The buckles are also releasable manually. Between the gas connection to the buckles on the lap belt and the manipulable device or cartridge casing is a disconnect anchored to the plane which, when the pilot is ejected from the plane, disconnects the gas connection of the lap belt buckles from the gas supply or cartridge casing, so that when the crewman lands, he can manipulate the cartridge piercing device to be quickly released from the parachute harness, without releasing the lap belt buckles which latter support the survival kit in convenient position on the crew man.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
In combination with a parachute harness having releasable buckles for connecting to the harness, riser straps from the parachute and having buckles connecting to the harness lap belts supporting a survival kit, harness release means comprising, means actuated by gas under pressure for releasing the respective buckles, supply means connected to the respective gas actuated means for supplying gas under pressure at will for release of the buckles, disconnect means interconnected between said gas supply means and the buckles of said lap belt normally being in position to conduct gas under pressure to the lap belt buckles, and means actuated by the ejection of the wearer of the harness from the aircraft for disconnecting said disconnect device from said gas supply means.
Claim 2
Dependent Claim
122 words
In combination with a parachute harness having releasable buckles for connecting to the harness, riser straps from the parachute and having buckles connecting to the harness lap belts supporting a survival kit, harness release means comprising, means actuated by gas under pressure for releasing the respective buckles, supply means connected to the respective gas actuated means for supplying gas under pressure at will for release of the buckles, disconnect means interconnected between said gas supply means and the buckles of said lap belt normally being in position to conduct gas under pressure to the lap belt buckles, and means actuated by the ejection of the wearer of the harness from the aircraft for disconnecting said disconnect device from said gas supply means.
Claim 3
Dependent Claim
20 words
The invention specified in claim 1, and manipulable means on each of said buckles for manually releasing the respective buckles.
Claim 4
Dependent Claim
64 words
The invention specified in claim 1, and each of said gas pressure actuated means in each buckle including, a member connected to the respective strap, another member connected to the harness, a connecting element between said members for holding said members together, releasable means to hold said connecting element in connecting position, and means actuated by gas under pressure to release said releasable means.
Claim 5
Dependent Claim
40 words
The invention specified in claim 1, and a valve between said disconnect device and said gas supply means, means of connection between said disconnect means and said valve means for keeping said valve open until said disconnect means are disconnected.
Claim 6
Dependent Claim
20 words
The invention specified in claim 4, and manipulable means on each of said buckles for manually releasing the respective buckles.
Claim 7
Dependent Claim
59 words
The invention specified in claim 4, and said gas supply means including, a casing, a cartridge containing gas under pressure in said casing, manipulable means to pierce a cartridge to release gas under pressure therefrom, gas lines connecting said casing to the respective buckles, said disconnect means being interconnected in the gas lines communicating with the lap belt buckles.
Claim 8
Dependent Claim
30 words
The invention specified in claim 6, and a normally closed valve interconnected between said disconnect device and said casing, and means on said disconnect device to keep said valve open.
Claim 9
Dependent Claim
59 words
The invention specified in claim 7, and said normally closed valve being a ball on a valve seat in said casing closed by the released gas pressure in said casing, said means to keep the valve open, including a projection from said disconnect means into said casing in the connecting position to lift said ball off said valve seat.
