The Next-Generation Seatbelt Airbag System.
The AmSafe® Seatbelt Airbag is the first and only airbag system certified for use on commercial aircraft. It was developed as a cost-effective method of 16g compliance for difficult-to-certify seat placements. AmSafe has improved on this state-of-the-art technology and developed a new version of the airbag system. The design is sleek, is substantial y light in weight, contains built-in test equipment diagnostics, and is optimized to support the ful class of service instal ations and fleet-wide retrofits. Just like the original design, the new Seatbelt Airbag looks and operates like a standard AmSafe restraint. In the unlikely event of an otherwise survivable accident, an inflatable bag stored in the lap belt portion of the seatbelt protects passengers of al sizes from traumatic head and neck injury. The Seatbelt Airbag has been in service for over 10 years and has become the most accepted technology solution used to certify chal enging seat configurations for over 70 airlines. The New AmSafe Seatbelt Airbag System
• Is 30 percent lighter in weight
• Has sleek design improvements, including compact airbag lap belt packaging and a new
• Has an increased service life (more than 40 percent)• Contains on-board diagnostics—manual y or through an integrated wireless system In addition to the above improvements, the AmSafe Seatbelt Airbag• Meets the 16g requirement for commercial passenger seats • Is a complete solution for FAR/CS/25.562, Head Injury Criteria (HIC), FAR/CS/25.785, and side-facing protection requirements • Has been proven to be the most cost-effective solution for compliance with the 2009 16g ruling• Meets commercial g-force requirements: 16g/part 121 crash worthiness standards System Components
The AmSafe Seatbelt Airbag is a self-contained, modular restraint system. It contains the fol owing four core components:• Seatbelt Airbag Assembly—When sensing the predetermined activation threshold, the airbag is deployed, cushioning the passenger. Deflating within mil iseconds, the system does not impede passenger egress. • Inflator Assembly—The inflator consists of a compressed gas cylinder and gas nozzle optimized for the aviation environment. The inflator has a life limit of 10 years. • Electronics Module Assembly (EMA) —EMA is comprised of the system electronics, crash sensors, and an advanced lithium battery. The sensor and electronics module detects and analyzes decelerations. The airbag will not deploy inadvertently during normal operations such as hard landing, random vibration, or food cart strikes on the seat. Deployment wil occur, however, when a force is at or above 9g’s for approximately 50 mil iseconds. The EMA has a life limit of 10 years. • Cable Interface Assembly—The cable interface assembly contains electrical connectors for maintenance & retrofit
AmSafe Seatbelt Airbag system function diagnostics need to be performed at 4,000 flight hours
for commercial applications. All maintenance procedures and diagnostics are performed by
pushing the test button on the EMA or by using the wireless software from AmSafe. Trained
technicians can easily perform the test. The AmSafe Seatbelt Airbag can be retrofitted into
existing aircraft seats for carriers looking to modify or upgrade their interiors.
