  • Patent number: 10391963
    Abstract: A method for diagnosing aircraft airbag initiators in air bag systems includes: providing a diagnostic circuit per aircraft seat, the diagnostic circuit being in a normally off condition and enabled by a user activation; providing a power supply independent of aircraft power; providing a momentary switch; providing a visual indicator; receiving a signal indicating user activation of the momentary switch; and responsive to receiving the signal: completing a circuit, regulating a current into the diagnostic circuit to prevent a squib from firing during diagnostic evaluation; detecting a voltage; and providing feedback to the user.
    Type: Grant

  • Patent number: 9827938
    Abstract: The present invention discloses embodiments of an apparatus, system and related method for diagnosing initiators in air bag systems. An embodiment of the system comprises a diagnostic circuit electrically connected between acceleration switches and one or more squib, that is user-activated via a momentary switch, and with user-feedback, wherein a user can diagnose the health of the one or more squib with no power drain while inactive. An embodiment of a method related to the system comprises activating a momentary switch, completing a circuit whereby a diagnostic circuit may function, indicating to the user that the diagnostic circuit is functioning, regulating the current into the diagnostic circuit so that the squib does not fire, boosting the signal to a window comparator, detecting the desired voltage by the window comparator, giving feedback to the user that the voltage is good, too high, or too low.

  • Publication number: 20100270786
    Abstract: A high mobility restraint for a side facing vehicle occupant allows the occupant's trailing shoulder to rotate forward during the vehicle collision by a controlled amount after the restraint is activated, and allows the occupant's lower torso to move by a controlled amount in the vehicle direction of travel during the vehicle collision after the restraint is activated.

  • Patent number: 7481399
    Abstract: A position securing system for restraining an occupant in a vehicle includes a harness placed about an occupant's body and including a two-part lap belt defining two lap belt straps, two leg loops, a rear belt, two shoulder belts, a back belt, and a belly-side center buckle. Anchored to the vehicle and interacting with the lap belt straps are a plurality of retractors connectable to the vehicle and interacting with the shoulder belts and the belt straps of the lap belt in one-to-one correspondence, wherein at least the retractors interacting with the lap belt straps are each constructed to include a winding drum for winding in a reel-in direction a traction member which is integrated in the lap belt strap, with the winding drum loaded by a spring in the reel-in direction. Rotation of the winding drum at least in a pay-out direction of the traction member is automatically blocked by a locking mechanism, when the occupant assumes the seated position.
