Embodiment Construction

[0016] figure 1 is a block diagram of an electronic module assembly used to control one or more personal restraint devices (such as airbags or seat belt pretensioners) in an aircraft. Aircraft can be commercial airliners, small aircraft used in general aviation, military aircraft including fixed wing aircraft or helicopters. While the following description focuses on the application of the disclosed technology in an aircraft, it is understood that the technology may be used in other vehicles, such as powered boats, passenger trains, subways, buses, school buses, and the like.

[0017] In the disclosed embodiment, processor 20 is configured to execute a series of programmed instructions to detect the signal generated by crash sensor 24 in the event of sudden deceleration. Receipt of the signal from the crash sensor causes the processor to create an electrical current path between the power source (eg, battery) 30 and the inflator 60 which provides the gas required to inflate t...

Abstract

An electronic module assembly for controlling the deployment of one or more airbags (68) in an aircraft includes a power source (30), a crash sensor (24) configured to produce a signal in response toa crash event and an accelerometer (28) that is configured to produce a signal in response to a crash event. A processor (20) starts a timer upon detection of the signal from the crash sensor. When the processor receives a signal from the crash sensor, the processor is configured to determine if a signal has also been received from the accelerometer and if signals from both the crash sensor and the accelerometer indicate a crash event then the processor reads a memory associated with an inflator (60). The processor reads a timing value selected for the inflator and fires the inflator when thetimer has a value equal to the timing value selected for the inflator.

Description

technical field [0001] The disclosed technology relates generally to vehicle restraint systems, and in particular to systems that control airbags used in aircraft. Background technique [0002] Although air bags have been required as safety equipment in U.S. cars since 1998, the technology has not been widely used in aircraft until recently. Currently, airbags are commonly used in business-class and first-class passenger seats on commercial airliners, as well as many pilot seats in general aviation. In most airbag systems, a controller is configured to receive a signal from a crash sensor and supply current to an inflator that generates gas to inflate the airbag. Controllers used in the aircraft environment are more complex to design with special requirements. First, controllers used in the aircraft environment are battery powered and must be able to operate for 10 years plus an additional year without battery replacement. Second, to save cost, the controller must be able...
