AmSafe is the world's leading provider of safety restraint products for the aerospace, defense, specialty and vehicle industries and they recently received FAA approval on the first and only seatbelt airbag system for use on commercial flights. In the event of a survivable accident, an inflatable bag stored in the lap belt portion of the seatbelt protects passengers of all sizes from traumatic head and neck injury.
Each passenger will have an airbag installed in their seatbelt with a diagnostic module located underneath their seat. The airbag will not deploy accidentally during normal operations such as hard landing, random vibration, or food cart strikes on the seat. Deployment will occur; however, when a force is at or above 9g's for approximately 50 milliseconds.
Cubbison's membrane switch is located on the EMA (Electronic Module Assembly) and is the power and signal input control on the diagnostic module for the airbags. The EMA contains the system electronics, crash sensors, and an advanced lithium battery. All maintenance procedures and diagnostics are performed by pushing the test button on the EMA or by using the wireless software from AmSafe. RFID will then be used to communicate with the EMA module.
Cubbison's relationship with AmSafe Aviation began about 2 years ago. Our design team, led by printed electronics engineer, Yvonne Smith spent countless hours designing the membrane switch for AmSafe Aviation's seat belt airbag system. Yvonne really enjoyed working on this project. She said," Working with Peter Settles and the rest of the AmSafe team during the design phase was truly an honor, as well as a great learning experience." The Cubbison team is excited about this collaborative relationship with AmSafe Aviation.
