Abstract
Abstract The invention concerns release mechanisms and parachute harnesses having such mechanisms, the purpose of the invention being to permit donning of a harness by a person before entering an aircraft or like vehicle and to permit release of the parachute therefrom rapidly in certain emergency conditions, the mechanism comprising a release mechanism comprising a first coupling part; a second coupling part; clasping means adapted to receive and releasably retain said second coupling part; directly manually operable release means for effecting release of said clasping means being provided on the first coupling part; and second release means also for releasing said clasping means; a remotely positioned release member; said second release means being arranged to operate in response to pressure fluid on actuation of said remotely positioned release member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
271 words
A harness adapted to be worn by an airman and having shoulder straps and solely the shoulder straps to be secured to lift webs of a parachute, comprising 1. a pair of first connector parts secured to the harness shoulder straps, 2. a pair of second connector parts secured to the parachute lift webs, a. the first and second connector parts forming a pair of releasable connectors, 3. clasping means releasably securing the first and second connector parts of each of the connectors, 4. a first, directly manually operable release means for releasing the clasping means between the first and second connector parts of each connector, and 5. a second, fluid pressure responsive release means for releasing the clasping means between the first and second connector parts of each connector, the second release means including a. a supply of pressure fluid, b. a handle located remote from the first release means against the chest or abdomen of the airman and operable to release pressure fluid from said supply, c. a first conduit coupled to the handle and to the first connector part of one of the connectors for delivering the released pressure fluid upon operation of the handle, the delivered pressure fluid releasing the clasping means of the one connector, and d. a second conduit passing from the first connector part of the one connector to the first connector part of the other connector to transmit the delivered pressure fluid for releasing the clasping means of the other connector whereby the clasping means of the connectors may be selectively released by the directly manually or the pressure fluid responsive release means.
