In various embodiments, the present disclosure provides an energy attenuating mounting foot comprising a load beam having a longitudinal axis, a top surface, a bottom surface, an inner track interface lobe, and an outer track interface lobe, the inner track interface lobe and the outer track interface lobe extending laterally from the load beam, and a channel along the longitudinal axis having a depth extending from the load beam bottom surface toward the top surface. In various embodiments, the inner track interface lobe has a first length extending in a direction from the bottom surface towards the top surface and the outer track interface lobe has a second length extending in a direction from the bottom surface towards the top surface, the first length being less than the second length.

The safety barrier for aircraft seats is configured for use with a commercial aircraft. The commercial aircraft further comprises one or more seats. Each individual seat selected from the one or more seats further comprises an armrest. The individual seat is configured for use with by a client. The client sits in the individual seat. The safety barrier for aircraft seats is configured for use with the armrest. The safety barrier for aircraft seats comprises a knee shield and elbow parapet. The knee shield attaches to the armrest. The elbow parapet attaches to the armrest. The knee shield is a rotating barrier. The knee shield forms a barrier that prevents a knee of the client from entering the aisle of the commercial aircraft. The elbow parapet is a stationary barrier. The elbow parapet prevents the elbow of the client from entering the aisle of the commercial aircraft.

A vehicle including a housing, and a vehicle seat disposed in the housing. The vehicle further includes at least one radial slit disc energy attenuation assembly having an upper end coupled to the vehicle seat and a lower end coupled the housing. The radial slit disc energy attenuation assembly includes a slit disc stack having a plurality of deflectable discs configured to deflect in response to realizing a force applied by the vehicle seat.

A device for controlling the breakover rate of a seatback in response to a dynamic event (regulating the breakover velocity so as to achieve optimal velocity differential to the impact velocity of a passenger's head impacting with the seatback) is attachable to the seatback and to the seat frame; when a breakover event is triggered, the passage of a head injury criterion (HIC) pin through a controlled traveling slot is impeded by energy absorbing materials selected, e.g. for material composition and structure, to restrict the breakover velocity of the seatback to optimize velocity differential between the breakover velocity and the impact velocity by engaging the HIC pin and deforming at a predetermined deformation rate.

An adjustable leg restraint for an ejection seat may be configured to translate between an extended state and a nonextended state. The adjustable leg restraint may include a leg located proximate a side panel of the ejection seat. An extension flange may be coupled to the leg guard. The extension flange may be configured to translate the leg guard relative to the side panel of the ejection seat.
