摘要： A pretensioning lapbelt apparatus where the pretensioning of the lapbelt is performed by the rapid inflation of an airbag that is integral to the lapbelt itself. The design of the airbag, including the attachment locations of the ends of the webbing are chosen such that, upon inflation of the airbag, the free end of the webbing—the end of the webbing that is passed through the cinching latch—is pulled taught, thereby reducing the effective length of the lapbelt. The anchor is designed to be a cinching anchor such that once the airbag deploys and pulls the webbing through the anchor (thereby pretensioning the lapbelt) a sliding pin in the anchor “cinches” the webbing, effectively locking the webbing in the pretensioned state.

摘要： An airbag system for repositioning a seat occupant in a moving vehicle during a crash event includes: a first inflatable airbag disposed proximate to a front portion of a seat pan; a second inflatable airbag disposed proximate to a rear portion of the seat pan; and inflation control device controlling deployment of the first and second inflatable airbags. The inflation control device includes a programmable controller controlling inflation parameters of the first and second inflatable airbags to achieve a desired lift, subject to monument constraints.

摘要： 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. An apparatus embodiment of the present invention may comprise an electronics control module for sensing a crash event and initiating an inflation sequence for one or more airbags with an integrated system for diagnosing one or more initiators. The apparatus may include a housing enclosing one or more circuit boards, to which may be electrically connected one or more wire harnesses which themselves are electrically connected to one or more squibs.

摘要： The present invention discloses a multiple-chamber airbag structure where the airbag design has at least a stiff lower section to reduce the chest velocity and a soft upper section to meet the HIC requirements. Although stowed and deployed as a unitary airbag, the present invention includes separate chambers, which allows for independent gas inflation and stiffness control with venting.

摘要： The invention consists of various embodiments of a system that uses electromechanical means to alert a vehicle operator of an imminent vehicle roll-over and protect the operator in a roll-over event. The system uses an electronics control unit (ECU) that is able to detect the deflection angle of the vehicle's tilt with the horizontal. If this angle exceeds a certain amount, the operator is alerted of the increased risk of roll-over via haptic feedback whereby the ECU controls a seatbelt electromechanical system to create a haptic feedback alert to the operator. If the angle exceeds a second higher amount, the system braces the operator for a roll-over event by tightening the seatbelt, thereby better protecting the operator. The fact that the system is electromechanical, instead of pyrotechnical, makes the system reusable. Another embodiment of the invention comprises a safety process used by the ECU to alert and protect the operator. By conducting this procedure, the ECU is able to detect when a critical angle has been exceeded by the vehicle and what response is appropriate for the circumstance.

摘要： A method of making a flame resistant airbag suitable for use in aviation applications is discussed. A flame resistant fabric for the use in the construction of aviation airbags is woven from a high tenacity continuous polyester fiber substrate. A polyurethane coating is applied to the woven fabric, which has been treated with a flame retardant, to impart high pressure permeability resistance to the flame resistant fabric. The resulting fabric complies with Federal Aviation Requirement 25.853 as well as exhibits sufficient high pressure permeability resistance which is measured as a pressure of not less than about 198 kPa after five seconds from an initial inflation and pressurization to about 200 kPa, such as may be encountered in and during an inflation of aviation airbag assemblies.

摘要： 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.
