A leg restraint system for an ejection seat may comprise a leg restraint and a reel assembly coupled to the leg restraint. The reel assembly may include a drum configured to rotate about an axis. The leg restraint may be configured to wind around the drum in response to rotation of the drum about the axis.

A fitting for use with an ejection seat system of an aircraft includes a fitting bar configured to extend across a top of a catapult of the ejection seat system and defining an angled slot configured to receive a portion of a gas port of the ejection seat system. The fitting further includes a first leg and a second leg coupled to and extending away from the fitting bar and configured to be pivotally coupled to a smokestack structure of the ejection seat system.
