Development and Testing of an Automatic Lap Belt Retraction and Release System

摘要

The consequences of a poor or loosely adjusted restraint system have been well documented and have been shown to cause various crewmember injuries and also to degrade ejection seat performance. An automatic lap belt retraction and seat-man release system has been developed for use with the Navy's Maximum Performance Escape System ejection seat. The lap belt cinch-up device works simultaneously with the action of the inertia reel from independent gas generators, while the lap belt release device work simultaneously with the strap cutter from a common gas generator. In-house testing of improved cinch and release prototype devices is continuing. (Author)
