Disclosed is a system and method for passenger safety. A sensing unit, remote device, and/or fob may interoperate to provide various alerts and other indications representative of aspects of a context environment proximate to a sensing unit. In this manner, passenger safety may be enhanced.

Disclosed herein are system, method, and computer program product embodiments for detecting, alerting, and acting to prevent unattended vehicle deaths. An embodiment operates by receiving one or more signals from one or more presence sensors in a vehicle and analyzing the signals to detect the presence of a person or animal inside the vehicle. The system further receives one or more signals from one or more environment sensors on the vehicle and analyzes the signals to detect a dangerous environmental condition. If the system determines that both the presence of a person or animal has been detected inside the vehicle and a dangerous environmental condition has been detected, it activates one or more vehicle systems that mitigate the dangerous environmental condition and sends an alert to one or more predetermined recipients.

A buckle device capable of displaying a locked state includes a main body unit, a latch unit, a fastening unit, an electromagnetic unit, and a control unit. The main body unit includes a main body and the latch unit includes a detachable tongue element. The fastening unit includes a bolt body interfering with the tongue element. The electromagnetic unit includes an electromagnetic module and an electromagnetic rod. The electromagnetic module controls the electromagnetic rod to interfere with the bolt body. The control unit includes a control module, a display module and a magnetic rod detection module for detecting the position of the electromagnetic rod. The control unit receives detection information of the magnetic bolt detection module and controls the display module to display a current state according to the position of the at least one electromagnetic rod.

A seat belt fastened/unfastened state detection switch includes: a printed substrate that includes a circuit for detecting a fastened/unfastened state of a seat belt; a rotor that is rotatably attached to the printed substrate, includes a contact portion, the contact portion coming into contact with a tongue of the seat belt, and rotates in a forward direction in accordance with pushing of the tongue into a buckle; a spring that makes the rotor, the rotor being in a rotated state in the forward direction, rotate in a reverse direction in accordance with pulling of the tongue from the buckle; and an electric brush that is attached to a surface of the rotor, the surface facing the printed substrate, and includes a leg portion whose contact/non-contact state with respect to a conductive part of the circuit changes depending on a rotation state of the rotor.

A vehicle seatbelt monitoring system for monitoring seatbelts of a plurality of seats comprising: i) a buckle sensor for each seat configured to determine whether a seatbelt is buckled into a buckle attachment of each seat; ii) a seatbelt webbing payout sensor for each seat configured to determine an amount of seatbelt webbing that is unwound from a seatbelt retractor associated with each seat; and iii) a seatbelt monitor control module coupled to the buckle sensor and the seatbelt webbing payout sensor and configured to receive buckle state data from the buckle sensor for each seat and seatbelt payout data from the seatbelt webbing payout sensor for each seat. The seatbelt monitor control module is further configured to determine if a first seatbelt is unbuckled or not properly worn and, if so, to determine if a second seatbelt is buckled or properly worn when the first seatbelt is unbuckled or not properly worn.

An example embodiment of a system and methods for detecting and reporting whether passengers are seated and secured in their seats within a vehicle may include a passenger sensor configured to provide an output indicative of a presence of a passenger in a seat in a vehicle, a restraint sensor configured to provide an output indicative of a status of a passenger safety restraint associated with the seat, a transmitter configured to be in electronic communication with the passenger sensor and the restraint sensor and to wirelessly transmit data indicative of the presence of a passenger in the seat and the status of the restrain, and a reporting module configured to be disposed proximate a driver of the vehicle. The reporting module may be configured to receive the data from the transmitter, and output a respective status for each of a plurality of seats.

A seatbelt having a receiver having an opening configured to receive a latch-plate, an extended pushbutton at least partially disposed within the receiver, and a magnet at least partially disposed within the extended pushbutton, wherein the magnet is configured to align the latch-plate with the opening.

A harness buckle locking assembly for a buckle of for a car seat includes an On-Board Diagnostics (OBD) device, comprises a first transceiver and is configured to operationally engage an OBD II port of a vehicle, and a housing, which is positionable over a release button of a buckle of a car seat. A depressible button is attached to a pin and can be depressed to actuate the release button. A lock unit selectively locks the pin within the housing. An electronics unit is operationally engaged to the lock unit and communicates with the OBD device and with an electronic device of a user. The electronics unit can signal the user of occupancy of the car seat, when the vehicle has been turned off for a preset time, and also can selectively actuate the lock unit to unlock the pin.

A system includes a seatbelt buckle. The system includes a latch plate releasably engageable with the seatbelt buckle. The system includes an actuator operatively coupled to buckle to trigger disengagement of the latch plate from the seatbelt buckle. The system includes a computer having a processor and a memory storing instructions executable by the processor to detect an impact to a vehicle. The instructions include instructions to, in response to detecting the impact, command the actuator to trigger disengagement of the latch plate from the seatbelt buckle. The instructions include instructions to, after triggering disengagement of the latch plate, detect disengagement of the latch plate from the seatbelt buckle. The instructions include instructions to, in response to detecting disengagement of the latch plate from the seatbelt buckle, actuate an audio device to produce a sound.

Child seat monitoring system for a vehicle (e.g., using a computerized tool) is enabled. For example, a monitoring system for a child seat in a vehicle can comprise: a human machine interface unit, and a control unit, wherein the human machine interface unit comprises a sound system and a display unit, wherein the sound system is configured to capture a lock sound of a seat belt of the child seat, wherein the control unit is configured to identify if the lock sound corresponds to a predetermined safe locking sound of the seat belt, and wherein the control unit is configured to indicate in the display unit that the seat belt of the child seat is locked.
