Abstract:
Vehicle occupant restraint systems that include a compact, web-mounted airbag that can be deployed during a crash event are described herein. In some embodiments, the web (e.g., a shoulder belt) passes through the stowed airbag during normal use and, when the airbag inflates and deploys, the airbag extends along the length of the web (for example, along the entire length, or at least most of the length, of the web) to protect the occupant. In some embodiments, the restraint systems include shoulder belts having first and second overlapping web portions, and when the airbag inflates and deploys, the airbag extends along the length of the first web portion between the first web portion and the second web portion.
Abstract:
An electronic module assembly (EMA) for use in controlling one or more personal restraint systems. A programmed processor within the EMA is configured to determine when a personal restraint system associated with each seat in a vehicle should be deployed. In addition, the programmed processor is configured to perform a diagnostic self-test to determine if the EMA and the personal restraint systems are operational. In one embodiment, results of the diagnostic self-test routine are displayed on a display included on the electronic module assembly. In an alternative embodiment, the results of the diagnostic self-test routine are transmitted via a wireless transceiver to a remote device. The remote device can include a wireless interrogator or can be a remote computer system such as a cabin management computer system.
Abstract:
An unmanned air module includes one or more rotors, engines, a transmission and avionics. Any of several different ground modules may be attached to the air module. The air module may fly with and without the ground module attached. The ground module may be a vehicle ground module and may be manned. The vehicle ground module may transport the attached air module across the ground. The air module may have two rotors, which may be ducted fans, and three different configurations: a tandem rotor configuration, a side-by-side configuration, and a tilted-rotor configuration.
Abstract:
A crash attenuation system has an airbag inflatable generally adjacent to an exterior of the aircraft. The system includes a gas generator in fluid communication with an interior of the airbag. The system also includes a vent system having a vent passage supported by the aircraft, the vent passage being configured to allow gas to escape from within the airbag during an impact to a second set of airbags for flotation. The vent system also includes an actuator door for sealing the vent passage, thereby preventing gas from leaving the airbag. The actuator door is actuated by an actuator, the actuator being in fluid communication with the gas generator through an actuator duct. The system operates such that deployment of gas from the gas generator causes the actuator to inflate, thereby causing the actuator door to seal the vent passage. The gas generator is configured to re-inflate the airbag after the actuator door seals the vent passage.
Abstract:
A protective device (10) for protecting an occupant (7) of a vehicle (1), said protective device comprising an airbag (11) and inflation means (12) for inflating said airbag (11), the inflation means (12) being connected to the airbag (11) via a feed pipe (13) for feeding inflation fluid for the purpose of inflating the airbag (11) under predetermined conditions. This protective device further comprises expulsion means (20) for expelling said fluid, which expulsion means co-operate with at least one water detection means (15) so as to act when water is detected to remove said fluid resulting from inflation of the airbag (11), said airbag (11) being provided with a peripheral elastic strap (50) for optimizing the deflation of said airbag (11) when said expulsion means (20) allow said fluid to be removed from the airbag (11).
Abstract:
A shock absorbing apparatus for an aircraft seat that attenuates shock to passengers and crews includes; an airbag 11 being expanded in a plate shape in a state of less than maximum expansion; an upper flat plate 12 arranged on one side of the airbag 11; a lower flat plate 13 arranged on another side of the airbag 11; a gas supply device 15 for supplying a gas to the airbag 11; and a detector sending a signal to activate the gas supply device 15 by a preset condition. The shock is absorbed by expanding the airbag 11 before the shock is applied to the passenger.
Abstract:
Provided are an aircraft airbag that inflates across a plurality of seats, an airbag device including this airbag, and an aircraft equipped with this airbag device. The airbag has a bag main body extending across three seats and in the left-right direction of the aircraft body, and partition panels that partition the inside of the bag main body into small chambers and corresponding to the seats. Gas from the inflator flows into the small chamber in the middle, and flows into the small chambers through the communication portions above and below the partition panels. When occupants are caught and thereby the pressures in the small chambers reach a predetermined value or more, vent holes open.
Abstract:
Embodiments of the present invention provide an airbag system formed from non-traditional or asymmetric airbag shapes that deflect a vehicle occupant away from an interior vehicle structure.
Abstract:
A crash attenuation system for an aircraft includes an airbag carried by the aircraft that is inflatable generally adjacent an exterior of the aircraft. The airbag is in fluid communication with at least one vent passage for channeling gas from within the interior of the airbag to a region external to the airbag that allows the gas to escape without being obstructed by the airbag. A gas source is in fluid communication with the interior of the airbag for inflating the airbag. A vent valve is provided within the vent passage for controlling a flow of gas through the vent passage, thereby controlling deflation of the airbag. The vent valve is continuously adjustable to and between an open state, a closed state, and any number of partially open states.
Abstract:
A crash attenuation system for an aircraft, the system having an airbag carried by the aircraft and inflatable generally adjacent an exterior of the aircraft. The airbag has at least one vent for releasing gas from the interior of the airbag. A gas source is in fluid communication with the interior of the airbag for inflating the airbag with gas generated provided by the gas source. A vent valve is provided for controlling a flow of gas through each vent, each vent valve being selectively configurable between an open state, in which gas can pass through the associated vent from the interior of the airbag, and a closed state, in which gas is retained within the interior of the airbag. The gas source is provided for at least partially re-inflating the airbag after venting of gas through the at least one vent.
