A life preserver head restraint may be configured to inflate in response to deployment of a parachute assembly. The life preserver head restraint may comprise an inflatable volume and a charge tank fluidly coupled to the inflatable volume. In an inflated state, the life preserver head restraint may restrict head movement during line stretch of the parachute assembly.

An energy absorbing assembly includes an attachment component configured to be coupled to a mounting structure. The energy absorbing assembly also includes an anchor that has a tip portion, a shaft, and a head. The anchor is configured to extend through the attachment component such that the head is disposed on a first side of the attachment component and the tip portion is disposed on a second side of the attachment component and is configured to be coupled to the mounting structure. The energy absorbing assembly also includes a deformable member configured to be positioned concentrically around the shaft of the anchor. The deformable member is configured to be retained between the first side of the attachment component and the head of the anchor.

A control device including at least one control member for measuring an acceleration of an aircraft, for generating an inflation order, and for transmitting the inflation order to an inflation member, the inflation member serving to inflate at least one inflatable safety bag, the control device, the inflation member and the inflatable bag being arranged together on a single seat of the aircraft. Such a control device includes at least one readying system connected to the at least one control member, the readying system comprising: at least a first sensor suitable for continuously measuring a first current acceleration of the aircraft relative to at least one axis; and at least one switch that is controllable as a function of the first current acceleration of the aircraft as measured by the first sensor.
