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 electronic module assembly for controlling the deployment of one or more airbags in an aircraft includes a power source, a crash sensor configured to produce a signal in response to a crash event and an accelerometer that is configured to produce a signal in response to a crash event. A processor 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. The processor reads a timing value selected for the inflator and fires the inflator when the timer has a value equal to the timing value selected for the inflator.

Abstract: Various embodiments of vehicle occupant safety systems having extendable restraints for use with, for example, airbags are described herein. In one embodiment, for example, the disclosed technology includes a 2-point occupant restraint that secures an occupant in an aircraft seat. In this embodiment, the aircraft seat is positioned in a seating area that includes a forward monument housing a stowed airbag. In the event of a crash or other significant dynamic event that causes, for example, a rapid deceleration of the aircraft above a preset magnitude, the airbag deploys between the occupant and the monument as the dynamic forces cause the occupant to pitch forward. The forward momentum of the occupant's body creates a significant tension load in the 2-point restraint, which causes the restraint to extend by a preset amount, thereby allowing the occupant to move forward in the seat more than the occupant would have moved had the occupant been wearing a conventional, non-extending 2-point restraint.

Abstract: An airbag assembly for leg flail protection and associated systems and methods are described herein. An airbag system configured in accordance with an embodiment of the present technology can include, for example, a housing having a cavity and an opening in communication with the cavity, an airbag stowed within the cavity, and an inflator operably coupled to the airbag. The airbag can be configured to deploy through the opening of the housing during a crash or other significant dynamic event. The airbag can deploy outwardly from the side-facing seat to reduce occupant leg rotation during the crash or other significant dynamic event. The airbag can be pushed out of the housing before it is fully inflated. The airbag can be stowed and include folded first and second opposing side portions such that when the airbag is deployed, the portion nearest the occupant unfurls toward the occupant prior to the other portion farthest from the occupant unfurling in a direction away from the occupant.

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: Active airbag vent systems and associated systems and methods are described herein. An airbag system having an active vent configured in accordance with an embodiment of the present technology can include, for example, a first inflator operably coupled to a first hose for inflating an airbag in response to a rapid deceleration event. The airbag system can further include a second inflator operably coupled to a second hose configured to release a vent or seam on the airbag to rapidly deflate the airbag after initial deployment of the airbag.

Abstract: Structure mounted airbag assemblies and associated systems and methods are described herein. An airbag system configured in accordance with an embodiment of the present disclosure can include, for example, a housing having a cavity and an opening in communication with the cavity, an airbag assembly within the cavity, and an inflator operably coupled to the airbag assembly. The airbag assembly can include an airbag configured to deploy through the opening of the housing during a crash event. The airbag system can further include a door removably positioned across the opening and configured to move away from the opening during airbag deployment. The housing can be affixed to an interior portion of an aircraft, forward of and offset from an aircraft seat.

Abstract: Various embodiments of restraint system pretensioning devices for use in land, air, and sea vehicles are described herein. In one embodiment, a seat unit for use in a military land vehicle or helicopter includes a stroking device that enables the seat to move downwardly in response to sudden movement. The seat unit also includes a seat belt or harness that extends around the occupant in the seat. Sudden movement of the seat in response to an explosion or hard landing causes a pretensioning assembly to automatically pretension the seat harness.

Abstract: Apparatuses, devices and systems for attaching seatbelts to anchoring structures in aircraft and other vehicles, are described herein. In some embodiments, such apparatuses include a modular connector having a base configured to be attached to an anchoring structure, a body configured to be attached to a seatbelt, and an annular lock configured to releasably couple the body to the base. In these embodiments, the body carries the lock adjacent to an aperture configured removably receive the base. When the body is pressed over the base, the base passes into the aperture and contacts the annular lock, expanding the lock outwardly around the base. The base continues moving though the aperture in the body until the lock retracts into a groove in base, thereby releasaby locking the body to the base.

Abstract: Airbag assemblies and associated systems and methods for use in aircraft and other vehicles are described herein that can provide crash protection for occupants seated in an upright position while not injuring or striking occupants in the brace position.
