摘要： An air bag firing circuit (10) comprises a firing path which includes in series a safing sensor (16), a squib (20), and a FET (22) operated under microprocessor control (24) in response to the output of an electronic crash sensor (26). A power supply (28) maintains a known voltage (Vc) across the firing path (12) sufficient to explode the squib (20) upon simultaneous "closure" of both the safing sensor (16) and the FET (22) operated by the microprocessor (24) in response to crash sensor output (26). Normally, upon detection of a failure in the electronic crash sensor (26), its supporting electronics, or the FET (22) actuated in response thereto, the microprocessor (24) reconfigures the firing threshold of the safing sensor (16), as by applying a current to its integral test coil (38) to increasingly bias the sensor's inertial mass away from its switch contacts (14). However, if a failure of the safing sensor (16) is detected, reconfiguration of its threshold is inhibited notwithstanding the failure of other circuit components to prevent inadvertent deployment of the air bag. Once the safing sensor (16) is reconfigured, the microprocessor (24) turns on another FET (46) to pull one side of the squib to ground, thereby removing the inoperable FET from the firing path and ensuring continued protection of the vehicle passengers until the sensor is serviced or replaced.

摘要： A circuit for a actuating a vehicle passenger safety restraint such as an air bag includes pyroelectric sensors (24), pressure transducers (32), and ultrasonic acoustic sensors (26) for sensing the presence, weight, and relative position of the passenger within a vehicle (10), respectively, which information is supplied to a control module (36) controlling operation of the restraint (14). The control module, which includes processor means, calculates the likely effectiveness of the restraint in preventing or otherwise mitigating injury to the vehicle passenger in the event of subsequent operation of the restraint. A signal lamp (38) is illuminated by the control module in the event that the passenger assumes a position which reduces the calculated likely effectiveness of the restraint below a threshold level therefor, thereby warning the passenger of the heightened risk of injury. Preferably, the control module uses the information generated by the sensors to supplement or otherwise corroborate other information received from inertia-type "crash" sensors (22) or frangible "crush" sensors, thereby ensuring operation of the restraint only in those instances where the passenger is indeed placed at risk. Most preferably, the restraint is capable of providing a variable response, and the control module adjusts the response of the restraint prior to triggering the operation thereof so as to provide maximum protection to the passenger against injury.

摘要： An air bag firing circuit comprises a firing path (52) including in series a safing sensor (54), a squib (56), and a crash sensor (58). Each sensor comprises normally-open switch means (94) operated by an inertial mass and shunted by a resistor (84). A battery (82) maintains a known voltage across the firing path while suitable control means (80) checks the integrity of the firing path by reading and comparing the voltages achieved at various points (86,88,90) thereabout. The control means further tests each sensor individually by sequentially operating suitable test means incorporated therein, such as means (92) for biasing the inertial mass of each sensor towards its switch means to operate same, while determining the effect of such testing on the voltages achieved about the firing path. Upon the detection of a sensor failure, the malfunctioning sensor is removed from the firing path as by operating low-resistance shunt means (98) therefor, or by operating means incorporated within the sensor for operating the switch means thereof without regard to acceleration, such as means (92) for biasing its inertial mass towards its switch means to close same, thereby ensuring continued protection of the vehicle passengers until the sensor is serviced or replaced. If the malfunctioning sensor is the high-threshold crash sensor (58), the control means operates means on the low-threshold safing sensor (54) to increase the threshold thereof upon removal of the crash sensor from the firing path, thereby providing continuing protection for vehicle passengers.

摘要： An acceleration sensor (10) comprises a tube (14) formed of an electrically-conductive non-magnetic material; a stop (30) defining an end of the tube which moves longitudinally thereof in response to temperature; a magnetically-permeable element, such as a iron washer (44), proximate with the end of the tube (14); and a sensing mass (46) in the tube (14) comprising a pair of permanent magnets (48) secured to the opposite sides of an iron spacer (50) so as to place a pair of like magnetic poles thereof in opposition. In operation, the sensing mass (46) interacts with the iron washer (44) so as to be magnetically biased against the stop (30), while the stop (30) moves longitudinally of the tube (14) to maintain a nearly constant threshold magnetic bias on the sensing mass (46) irrespective of variations in sensor temperature. The sensing mass (46) is displaced in response to acceleration of the housing (12) from its first position against the stop (30) towards a second position in the tube (14) when such acceleration overcomes the magnetic bias, while the tube (14) itself interacts with the sensing mass to provide magnetic damping therefor. Upon reaching the second position in the tube 14 , the sensing mass (46) bridges a pair of electrical contacts (54) with an electrically-conductive surface (56) thereof to indicate that a threshold level of acceleration has been achieved. An electrical coil (60) is secured proximate with the iron washer (44) which, when energized, reversibly magnetizes the latter, whereby the sensing mass (46) is either repelled to the second position in the tube or more strongly biased against the stop (30).
