An arm restraint assembly configured to pierce a canopy in response to expulsion of an ejection seat from a cockpit may comprise a primary arm configured to pivot relative to the ejection seat. A canopy piercer may be coupled to the primary arm. The primary arm may be configured to rotate to a fully-deployed position while located within the cockpit. An apex of the canopy piercer may be oriented toward the canopy, when the primary arm is in the fully-deployed position.

A vehicle with at least one emergency exit system, the at least one emergency exit system comprising a jettisonable component that is accommodated and locked in an associated frame structure of the vehicle in normal operation mode and releasable from the associated frame structure for being jettisoned from the vehicle in an emergency mode; and further comprising an emergency evacuation assistance device that is adapted to assist in an emergency evacuation of the vehicle via the associated frame structure in the emergency mode; wherein the emergency evacuation assistance device is attached to the jettisonable component such that the emergency evacuation assistance device is deployed by means of the jettisonable component when the jettisonable component is jettisoned from the vehicle in the emergency mode.

An emergency exit for a helicopter is described that comprises: a wall defining an opening; a removable part engaging the opening in a removable manner; and a seal interposed between the wall and the removable part. The seal is transformable between: a first configuration, in which it prevents removal of the removable part from the wall following application of a predetermined load on the removable part; and a second configuration, in which it allows removal of the removable part from the wall following application of the predetermined load on the removable part. The emergency exit comprises an insert interposed between the seal and the wall; at least one of the insert and the seal comprise at least one tooth engaging a recess with a shape corresponding to the tooth and defined by the other of the insert and said seal, when the seal keeps, in use, the removable part constrained to wall.

A canopy for an aircraft includes a transparent cover, and a severance cord coupled to the transparent cover. The severance cord includes a fragmenting pattern including a plurality of outer perimeter segments that define an outer perimeter of the fragmenting pattern, and a plurality of inner fragmenting segments that are inside the outer perimeter. The fragmenting pattern is configured to break the transparent cover into numerous fragments when the severance cord is detonated.
