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.

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.

A monument mounted airbag system includes an airbag assembly including at least an airbag mounted directly forward of a passenger, and configured to deploy away from the passenger along an intercepting course with a predetermined path of travel of the passenger. Additionally, the airbag may be configured to substantially conform to a monument disposed in proximity thereto, and may include side support, lower support, and active vents.

In an illustrative embodiment, a seat is oriented at an oblique angle with respect to a centerline of an aircraft fuselage, the seat having an Aircraft Passenger Restraint System (APRS) with a pre-tensioner and integral retractable shoulder and seat belt webbing. In an illustrative example, the ARPS may be a three-point restraint to control a seat occupant's upper body, head and torso area. In some embodiments, the ARPS may further control the forces on the lower spine and torso. In some applications, the ARPS may operate to control the Head Injury Criteria (HIC) levels for the seat occupant's head, as well as the neck twist and upper spinal forces, to meet aircraft certification requirements imposed by the Federal Aviation Administration (FAA) and/or European Aviation Safety Agency (EASA). In response to a deceleration event, the ARPS may rapidly retract the belt webbing to substantially remove slack.

A protection device having a set of inflatable protection members including a neck airbag, a left lower airbag, a left upper airbag, a right lower airbag, and a right upper airbag. The protection device has a lower pocket provided with a lower base forming the neck airbag and two lower lateral branches forming the left lower airbag and the right lower airbag. An upper pocket at least partially secured to the lower pocket is provided with an upper base forming a head airbag and two upper lateral branches forming the left upper airbag and the right upper airbag. At least one longitudinal internal wall provide at least two “tubes” in each upper airbag, the upper pocket being in fluid flow communication with the lower pocket.

An airplane seat device includes at least one airplane seat, and with at least one console arranged, viewed in a flight direction, in front of the airplane seat, and with at least one airbag element which is configured to protect in a crash event a passenger sitting in the airplane seat from crashing onto the console. At least one airbag element features, in a fully deployed state, at least in a head-impact zone, a thickness which is smaller than a thickness in at least one shoulder-impact zone.

Multi-chamber airbag systems for use in aircraft and other vehicles are described herein. In some embodiments, an occupant restraint system includes a multi-chamber airbag that deploys from an occupant restraint (e.g., a lap seat belt) in an aircraft. The multi-chamber airbag can include a first portion that inflates generally upward in front of the occupant's torso, and a second portion that inflates in front of the first portion. The first portion and/or the second portion can include multiple chambers (e.g., generally cylindrical-shaped chambers) that, when inflated, provide the airbag with a shape and/or contact surfaces which can help to maintain the position of the airbag between the occupant and a strike object or hazard. In other embodiments, multi-chamber airbags configured in accordance with the present disclosure can me mounted to a structure (e.g., a monument, console, seat back, etc.) positioned generally in front of the occupant. The structure-mounted airbag can deploy generally toward the occupant in the event of a vehicle impact or other potentially harmful event to protect the occupant from impact injury.

A lap expanding reactionary airbag apparatus includes separate expanding lap and chest portions of the airbag. When loaded in a frontal or oblique crash event, the two portions act as a reactionary surface against each other, reducing the chest velocity of a vehicle occupant, thereby reducing the forward movement of the occupant. This restriction in forward movement results in reduced lumbar injuries.

A life protection device system is proposed. More particularly, the life protection device system includes: a shock absorbing device provided with a shock absorbing part, a shock absorber, and an airbag that are mounted on a moving object so as to absorb impact to protect the life of passengers in a crash or collision of the moving object; a measuring device detecting the shock applied to the moving object; a controller generating a preset driving control signal according to the detected shock of the measuring device; and an artificial intelligence part notifying of an occurrence of a disaster and asking for help from a designated disaster center in response to the driving control signal of the controller, wherein the impact on the passengers is minimized even when the moving object such as a drone, autonomous aircraft, and autonomous vehicle crashes or collides, or falls into a river or sea.
