Abstract: A buckle assembly includes at least one socket to receive and retain at least one lug therein, and an emergency release arrangement. The emergency release arrangement is operable to release the at least one lug from the socket in response to a predetermined trigger signal. The assembly also includes a manually operable resetting arrangement that is operable to retain the lug(s) re-inserted into the socket(s), following the triggering of the emergency release arrangement.

Abstract: A rocket motor assembly (3) for use with an aircraft ejection seat comprises a rocket motor (4) having a rocket motor housing (5) and an exhaust outlet (6-9) to permit exhaust gas to be output from the rocket motor (4) along a thrust vector. The rocket motor assembly (3) comprises a first rotational coupling (12) which is configured to rotationally couple a first part (13) of the rocket motor housing (5) to a support structure (10) and a releasable coupling (14) which is configured to releasably couple a second part (15) of the rocket motor housing (5) to the support structure (10). The releasable coupling (14) is configured to release the second part (15) of the rocket motor housing (5) to permit the rocket motor housing (5) to rotate about the rotational coupling (12) to change the angle of the thrust vector of exhaust gas output from the exhaust outlet (6-9).

Abstract: A headrest assembly (1) for an ejection seat, comprising: a support mounting (2); and a pair of inflatable side beams (3), each attached at one end to the support mounting and spaced apart from one another, the side beams (3) being configured to be inflated from a stowed configuration to a deployed configuration in which the side beams extend from the support panel, the side beams (3) configured to deploy through: a capturing phase, during which the side beams are partially inflated from the stowed configuration such that they extend outwardly and upwardly from the support mounting and away from one another to surround the head of an occupant of the ejection seat toward a central location with respect to the support mounting.
