A seat assembly comprises a seat. The seatbelt securing system further comprises a seatbelt coupled to the seat. The seatbelt comprises a first strap and a second strap. The seatbelt further comprises a latch configured to selectively secure the first strap relative to the second strap. The latch further comprises a latch sensor configured to provide a secured indication in response to detection that the latch properly secures the first strap of the seatbelt to the second strap of the seatbelt and provide an unsecured indication in response to detection that the latch does not properly secure the first strap of the seatbelt to the second strap of the seatbelt. The latch further comprises a latch indicator to provide a warning in response to the unsecured indication.

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 method and apparatus for protecting a passenger during a crash comprises a moveable seat with an energy absorber (EA) that allows the seat to stroke a finite distance to decelerate the passenger in a controlled manner. The seat is designed so that one of a plurality of fixed profile EA's can be selectively engaged to provide a tailored EA composite profile adapted to the occupant's weight and anticipated crash environment. The tailored EA composite profile applies a frequency matched, low onset force to the seat, which substantially eliminates problems associated with dynamic overshoot of the passenger's spine.

A system for increasing passenger safety within an airplane (10) includes a forward seat (16) having a back surface (17) that faces an occupant seat (14). A tray table holder (22) is secured to or formed integrally with the back of the forward seat (16). A tray table (20) is rotatably connected to the tray table holder via a hinge (40) and is rotatable relative to the tray table holder. The tray table defines a cavity (32) inside the tray table. An airbag (54) is within the cavity. An inlet device (42) is coupled to the airbag and is rotatable about the hinge (40) such that the inflator inlet can rotate as the tray table rotates relative to the tray table holder. An inflator (52) is connected to the inlet device and is configured to deliver gas to the airbag through the inflator inlet.

A monument mounted airbag system for arresting passenger movement during a sudden acceleration/deceleration event of a moving vehicle includes an airbag assembly including at least one airbag on a first portion of a monument structure, the airbag assembly having a housing at least partially defined by a space between an external member and the monument structure.

An airplane seat device includes at least one airplane seat, and at least one console arranged, viewed in a flight direction, in front of the airplane seat, and 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.

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 knee protection apparatus for travel having a padding body. The padding body having a body length extending between two ends, a body width, a body thickness, a front surface, a bottom surface, and a rear surface. The padding body provides a cushion for when a user's knees press against the front surface of the padding body. The padding body attaches with at least one mounting mechanism mounted on the back surface of the padding body and configured to mount to a seat in front of the user during travel. A container is attached to the bottom surface of the padding body and configured to hold travel items.

A differential detection device detects a spatial difference. A measurement unit measures a position of each of a plurality of points in a surrounding local space. An extractor extracts attribute information on each of measured voxels that are three-dimensionally arranged and associated with the local space, from a measurement result of the measurement unit. A map management unit manages attribute information on each of map voxels that are three-dimensionally arranged and associated with the space shown on a map. A parameter setting unit sets a numeric value to a parameter according to an operation mode set by the user. A differential detector detects presence or absence of a difference between the attribute information on the measured voxel and the attribute information on the map voxel at a position corresponding to the measured voxel, by using the numeric value set to the parameter. An output unit outputs a detection result.
