Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An ejection seat, comprising: a head restraint system configured to deploy in response initiation of an ejection sequence; and a life preserver head restraint coupled to the head restraint system, wherein the life preserver head restraint is configured to inflate in response to a translation of the head restraint system. 2. The ejection seat of claim 1 , wherein the head restraint system comprises a rear support and a side support, and wherein the rear support and the side support are configured to pivot relative to a seat back of the ejection seat. 3. The ejection seat of claim 1 , further comprising: a charge tank fluidly coupled to the life preserver head restraint; and a lanyard configured to actuate a valve of the charge tank to an open position. 4. The ejection seat of claim 3 , wherein the lanyard actuates the valve to the open position in response to the head restraint system translating to a deployed position. 5. The ejection seat of claim 3 , wherein the lanyard actuates the valve to the open position in response to the head restraint system translating from a deployed position to a stowed position. 6. The ejection seat of claim 5 , further comprising a parachute assembly operationally coupled to the head restraint system, wherein the head restraint system is configured to translate from the deployed position to the stowed position in response to a deployment of the parachute assembly. 7. The ejection seat of claim 6 , wherein the lanyard is coupled to the parachute assembly, and wherein the deployment of the parachute assembly translates the lanyard.
