Abstract
A method may include receiving, via a processor, an ejection initiation signal indicating an ejection event for an ejection seat of an aircraft has been initiated; commanding, via the processor, a retraction mechanism to retract a cuff assembly towards a seat back of the ejection seat in response to the ejection initiation signal; and commanding, via the processor, a guillotine to sever a cord coupled to the cuff assembly.
Claims13
A retention system for an aircraft ejection system, the retention system comprising:
- a catapult configured to eject an ejection seat from an aircraft;
- a first cuff assembly disposed on a first side of the ejection seat;
- a second cuff assembly disposed on a second side of the ejection seat;
- a first cord extending from within the ejection seat to the first cuff assembly;
- and
- a second cord extending from within the ejection seat to the second cuff assembly, the retention system configured to allow a free range of motion of the first cuff assembly and the second cuff assembly during an aircraft flight, the retention system configured to retract and lock the first cuff assembly and the second cuff assembly in response to a seat ejection being initiated, wherein a pressure from the catapult is configured to retract the first cord and the second cord.

A retention system for an aircraft ejection system, comprising:
- a catapult configured to eject an ejection seat from an aircraft;
- a cuff assembly;
- a retraction mechanism;
- a cord extending from the retraction mechanism to the cuff assembly, wherein a pressure from the catapult is configured to retract the cord via the retraction mechanism;
- a guillotine configured to sever the cord;
- and
- a controller in operable communication with the guillotine, the controller configured to:
- receive, via a processor, an ejection initiation signal indicating an ejection event of the ejection seat has been initiated;
- and
- command, via the processor, severing of the cord after ejection of the ejection seat.
