An aircraft ejection seat assembly is disclosed where a survival kit is incorporated into a seat back of an ejection seat, and that is released from the ejection seat by one or more actuators. The survival kit is attached to the parachute lines. One or more retention pins may secure the survival kit relative to the seat back. Representative actuators that may be used to move the retention pin(s) to a release configuration including mechanical (e.g., a bell crank), electrical (e.g., a controller such as a MASS), or pressurized fluid.

A seat configured to support an occupant may include a urine-based power generator and an adjustable cushion. The urine-based power generator includes a urine accumulation reservoir configured to receive urine from the occupant, and the urine-based power generator is configured to provide power to the adjustable cushion. The seat may be an ejection seat, and the urine-based power generator and the adjustable cushion may be mounted to the seat such that the urine-based power generator and the adjustable cushion are configured to be ejected with the ejection seat.

A sequencer system for an ejection assembly may comprise a first A-side controller and a second A-side controller in operable communication with the first A-side controller. A first B-side controller may be in operable communication with the first A-side controller. A second B-side controller may be in operable communication with the first B-side controller and the second A-side controller. The controllers may be configured to each make an initial ejection sequence determination and a verified ejection sequence determination. The controllers may make the verified ejection seat determination based on a two of three voting scheme.

An arm restraint assembly for an ejection seat may comprise a primary arm configured to pivot about a primary arm pivot joint, and a secondary arm configured to pivot about a secondary arm pivot joint. A primary airfoil structure may be coupled to the primary arm assembly. The primary airfoil structure may include an airfoil body.

An arm restraint assembly for an ejection seat may comprise a primary arm configured to pivot about a primary arm pivot joint, a first cable portion coupled to the primary arm, and an attenuator coupled to the first cable portion. The first cable portion may be configured to pivot the primary arm about the primary arm pivot joint. The attenuator may include a housing and a plunger having a head located in the housing. The head of the plunger may be biased toward a first end of the housing.
