The present disclosure relates generally to the field of seat belts for passenger vehicles. More specifically the present disclosure relates to the field of passenger safety and compliance with respect to placing a seat belt into an engaged or locked position upon command.
Safety, including passenger safety, is important for any aircraft. The “Fasten Seat Belts” command is one component of the passenger safety. Various regulations (e.g., Commission regulation (EC) No. 859/2008 for the EU; Regulation 14 CFR § 91.107 for the US) determine the seat belt requirements for passenger aircraft. It is mandatory to fasten seat belts during taxi, takeoff and landing, and whenever further deemed necessary in the interest of safety.
Cabin crew members typically ensure this mandatory regulation safety check manually by going to each and every passenger seat. On occasion, the manual safety check by crew members not affirmatively appreciate the locked or unlocked state of a passenger seat belt.
Known solutions to the problem of ensuring compliance with a “Fasten Seat Belts” command have incorporated RFID chips to deliver a signal when a locking mechanism has been successfully or unsuccessfully accomplished in a seat belt assembly. However, merely determining that a seat belt assembly has been locked does not ensure that a seat belt assembly has been locked around the torso (e.g., waist, etc.) of a user, by a user. That is, the “locking requirement” of a seat belt assembly can be satisfied by a passenger engaging the assembly, while also circumventing the safety aspect of the seat belt by not actually wearing the seat belt. That is, a user/passenger may lock the seat belt assembly, generate a signal that the seat belt assembly is locked, but then, for example, sit upon the locked assembly.
According to present aspects, the present disclosure is directed to an apparatus, with the apparatus including a seat belt, with the said seat belt including a seat belt receiving end first side, a seat belt receiving end second side, a seat belt locking sensor, and a thermal sensor.
In another aspect, the thermal sensor is configured to sense at least one of: a seat belt receiving end first side temperature and a seat belt receiving end second side temperature.

The features, functions and advantages that have been discussed can be achieved independently in various aspects or may be combined in yet other aspects, further details of which can be seen with reference to the following description and the drawings.
Having thus described variations of the disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Present aspects include employing an “Internet of Things (IOT)-based” technology incorporated into a seat belt assembly (e.g., to form a “smart” seat belt assembly), that will help the commander/pilot and crew members of a passenger vehicle (e.g., a passenger aircraft, etc.) ensure that all passengers affirmatively comply completely with the “Fasten seal be/s” command that is mandated by regulations for safety. According to present aspects, the disclosed smart seat belt assembly includes a magnetic-based or switch-based sensor to ensure the locking condition of the seat belt lock as properly “locked” (e.g., securely engaged) or “unlocked” (e.g., disengaged). The smart seat belt assembly also incorporates a thermal sensor that can sense a thermal condition (e.g., human body heat equivalently referred to herein as “a thermal signature”) from, for example, a human torso, etc., to ensure that a passenger actually wears the belt properly, instead of just locking the belt (without wearing the belt properly).
Attached illustrations show the non-limiting designs of the smart seat belt and seat belt assembly.
According to present aspects,
According to present aspects, cabin crew members or flight officers, for example, can view, inspect, confirm, etc., the collected and displayed smart seat belt confirmatory information for all passengers at a single glance to ensure safety norms at the time of taxi, take-off, landing, or on demand as necessary, etc. That is, the present systems, apparatuses, and methods help cabin crew members to quickly and efficiently identify (e.g., from a crew member workstation), the passengers (based on smart belt unique number/seat number, etc.) that have not complied with safety norm without visiting and visually inspecting each and every passenger for the purpose of confirming a properly secured seat belt.
For example, according to present aspects, the disclosed seat belts, seat belt assemblies, and seat belt systems (e.g., as shown in
According to further aspects,
When the seat belt is properly worn by a user, the locking mechanism sensor 42 will detect the proper engagement of the locking mechanism, and the locking mechanism sensor 42 (that includes a locking mechanism transmitter not shown in
In addition, according to present aspects, substantially simultaneously with the information regarding the locking mechanism and the locking condition, the thermal sensor 44 transmits information regarding the real time temperature of the seat belt receiving end second side (e.g., the side of the seat belt receiving end that would be resting, or otherwise brought into contact with the torso of the body of a passenger wearing the seat belt, etc.). The thermal sensor that is incorporated into the presently disclosed seat belts and seat belt assemblies conclusively determines a locking condition of a seat belt assembly, and further ensures that the seat belt is actually being worn properly by a user/passenger (e.g., as opposed to a seat belt assembly has merely been engaged into a locking position—thus satisfying the locking function of the seat belt assembly, but that is not actually being worn by a user/passenger and, instead, for example, is locked, but is merely being “sat upon” by the user/passenger).
In addition, according to further aspects, to conclusively determine a locking condition of a seat belt assembly (e.g., that the seat belt assembly has not merely been engaged into a locking position—thus satisfying the locking function of the seat belt assembly) and to ensure that an otherwise “locked” or engaged seat belt assembly is merely being “sat upon” by the user (potentially satisfying a heat signature adequate to satisfy a temperature approximately equal to a human body torso), the thermal sensor senses, records, and transmits information regarding the temperature of both the seat belt receiving end second side and the temperature of the seat belt receiving end first side (e.g., the side of the seat belt receiving end that, when worn properly would be exposed to an ambient surrounding). By also sensing the temperature of the seat belt receiving end first side, when the seat belt is being worn properly, the thermal sensor senses a temperature difference between the seat belt receiving end second side (that has a temperature that is approximately equivalent to temperature of a human torso) and seat belt receiving end first side (that has a temperature that is approximately equal to an ambient cabin temperature).
According to one aspect, when the thermal sensor detects a temperature differential between various monitored and predetermined locations on the seat belt receiving end, a confirmatory signal can be transmitted from a thermal sensor transmitter to a receiver (e.g. a receiver in communication with an aircraft databus, or in communication with a controller configured to collect information and then provide collected information to a readout, etc.) confirming that a proper “locking” of the seat belt assembly has occurred (e.g., a specific seat belt assembly located at and associated with a particular seat location in, for example, a passenger aircraft cabin such as those shown in the readout display shown in
According to present aspects, the thermal sensor confirmation in combination with the locking mechanism confirmation ensures that a seat belt assembly at a specified location has been properly locked, and that the passenger wearing such seat belt assembly has complied with the “Fasten, Seat Belts” command.
