A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, generates a time-based record of the safety-compliance data. The computer system can use the time-based record to adapt cabin operations policy, including cabin temperature, cabin lighting, illumination of seatbelt signs, scheduling of meal or drink service, timing of inflight announcements, or the availability of in-flight entertainment.

In a triggering system for activating a safety device, an acceleration sensor outputs a signal for a time duration in which an acceleration impulse exceeds an acceleration magnitude threshold. A first switching device receives the signal output by the acceleration sensor, and electrically connects a power supply to at least one safety response device for the time duration. A time delay device, upon completion of a delay time after receiving the signal output by the acceleration sensor, outputs a signal for the time duration. A second switching device receives the signal output by the time delay device, and electrically connects the power supply to the at least one safety response device for the time duration. When the time duration exceeds the delay time, the first switching device and the second switching device concurrently electrically connect the safety response device to the power supply, activating the safety response device.

An arm restraint assembly for an ejection seat may comprise a primary arm and a primary arm deployment system operationally coupled to the primary arm. The primary arm deployment system may be configured to rotate the primary arm about a primary arm pivot joint. The primary arm deployment system may be configured to attach to the ejection seat such that the primary arm deployment system translates with the ejection seat.

A leg restraint system for an ejection seat may comprise a leg restraint and a reel assembly coupled to the leg restraint. The reel assembly may include a drum configured to rotate about an axis. The leg restraint may be configured to wind around the drum in response to rotation of the drum about the axis.

An object recognition computer for a vehicle includes at least one processor and at least one memory storing program code executable by the at least one processor to perform operations. The operations are configured to receive video streams from a plurality of cameras spaced apart within the vehicle and each having a field-of-view capturing at least one passenger seat. For each of the video streams, the operations retrieve from a data structure information that defines a region within video frames of the video stream where object recognition is to be performed to attempt to identify a defined object associated with the at least one passenger seat. The operations then perform object recognition limited to within the defined region to identify the defined object. Notifications can be selectively generated to passengers and/or crew based on the object recognition.

A head rest including: a Cushion and an Attachment Strap. The Cushion has a Pillow and Rigid Member with a back portion and two side portions generally U shaped such that the Cushion can form a compressible fit around the back of a person's head at or near the ear level. The exterior of the back portion of the Cushion is shaped to mate with a seat back and has attachment means such as Velcro on the outside. The Attachment Strap securely fits around the seat back and has a means such as Velcro for engaging the Cushion in order to hold the Cushion upright and in place. The Cushion can supply lateral or horizontal support a person's head in all directions because it is attached to the seat back and has a compression fit on a person's head.

The aircraft seatbelt buckle fasten indication system comprises a monitoring circuit, a plurality of tracking structures, a plurality of lap belts, and a plurality of vehicle seats. Each of the plurality of tracking structures attaches to a lap belt selected from the plurality of lap belts. Each individual tracking structure selected from the plurality of tracking structures attaches to a lap belt selected from the plurality of lap belts such that the selected individual tracking structure monitors the status of the lap belt. The status of the lap belt is selected from the group consisting of: a) the lap belt is properly fastened; and, b) the lap belt is not properly fastened. The monitoring circuit monitors each of the plurality of tracking structures to individually determine the status of each individual lap belt. The monitoring circuit provides a visual display of the status of each individual lap belt.

A functional unit in a passenger cabin includes a support unit and a passenger seat system. The passenger seat system is formed in two parts and has an upper constructional unit and a lower constructional unit that are each separate components, the upper constructional unit arranged on the support unit and containing at least one backrest, and the lower constructional unit containing a seat frame, at least one seat element and restraint for the passenger on the seat. The seat frame is fastenable to seat rails on the floor of a passenger cabin. For the use position, the upper and lower constructional units are positioned such that a passenger seat is formed. In the use position, personal comfort for the individuals on the seats is not impaired as far as possible, and the division of the seat system into two parts cannot be seen by the user.

A head support apparatus provides support to a persons head while the person is seated. In some embodiments, A seat strap passes around the seat back of a seat and is adjusted tightly enough to maintain itself in position. A support strap attaches in a least one place to the seat strap at the back side of the seat back. The support strap passes up over the top of the seat back and presents a sling at the front side of the seat back to support a user's head. The seat strap, support strap, and sling are adjustable. In other embodiments, a sling has spring powered reels associated with each end. A strap extends from each reel. Each strap has a coupler at its exposed end which may connect directly to a seat. Some embodiments include a seat having complementary couplers complementary to the couplers on the straps.

An interior configuration for an aircraft including a longitudinal aisle and rows of passenger seats, wherein a row of the passenger seats is disposed in a flexible use space adjacent the aisle and a bulkhead, and wherein the flexible use space includes a floor pallet and attendant seats equipped with flip-up seat bottoms such that the flexible use space can be configured for passenger seating or to provide securement space within the flexible use space for securing items such as a wheelchair, pet carrier, large items and items of value.
