Quick Release Buckle (QRB) is an automated seatbelt system. QRB utilizes a power source and control unit software incorporated into pre-existing components within the vehicle's transmission or by micro-switch. QRB automatically disengages the seatbelt upon placing the vehicle in “park”, regardless of the ignition setting for law enforcement/military vehicles. While in “park”, an electrical signal energizes a solenoid releasing the buckle. The control unit contains proprietary software that records every engage/disengage of the seatbelt. Electronic records can be downloaded at any time, using an integrated micro-scan disk (SD) module/card. During a collision, the system ceases to record activity, showing electronic proof the seatbelt was engaged/disengaged. Civilian application includes accident investigations, insurance inquiries, and private company regulation compliance. Civilian QRB differs slightly as the transmission must be placed in “park” and the ignition must be in “off” for system operation.

A technology is provided that secures the straightness of an electromagnetic wave signal transmitted and received according to the fastening of a buckle. A wireless seatbelt reminder device includes a tunnel member that is disposed in parallel to a seat rail, and has a passage formed therein. A sub-transmission and reception unit transmits an electromagnetic wave signal in the longitudinal direction of the passage as a seatbelt is fastened to a buckle and a main transmission and reception unit receives the electromagnetic wave signal transmitted by the sub-transmission and reception unit inside the passage to transfer the electromagnetic wave signal to an integrated controller.

An in-vehicle communication system includes a master control unit mounted on a vehicle, a plurality of slave devices mounted on the vehicle, a plurality of buckles provided in association with each of a plurality of seats mounted on the vehicle, and at least one switch unit configured to generate a signal in accordance with an attachment and detachment state of at least one of the plurality of buckles. The master control unit is communicably connected to each of the slave devices. The master control unit controls the plurality of slave devices based on the signal generated by the at least one switch unit.

Disclosed herein is an apparatus for detecting a passenger and wearing seat belt based on an image, which includes an image detector configured to detect an image of an interior of a vehicle, which is captured using a camera, a controller configured to analyze the image of the interior of the vehicle, which is captured through the image detector, and determine whether a passenger is present and whether the passenger wears a seat belt, and an information output part configured to output a warning or an alarm according to discrimination of the passenger from an object, which is determined by the controller, the presence or absence of the passenger, and whether the passenger wears the seat belt.

The invention relates to a sensor (310), in particular for triggering a vehicle safety device (301), having a movable inertia body (350) which is movable relative to a carrier element (340) of the sensor (310), wherein the inertia body (350) is moved by inertia in relation to the carrier element (340) in the event of an abrupt change in speed or an inclination of the sensor (310) beyond a predetermined extent, and is brought from its inoperative position into its triggering position, through which a triggering position of the sensor (310) is brought about.

According to the invention, it is provided that the sensor (310) is provided with a deactivation device (700) which is suitable, in its deactivating state, to force the inoperative position of the inertia body (350).

An inclination controlling mechanism of a seatbelt device is provided with: a pulley that converts an advancing/retracting movement of a cable of the cable advancing/retracting mechanism; a drive gear mounted around a pivot shaft of the pulley and synchronized with rotation of the pulley; and a driven gear mounted around a pivot shaft of a sensor housing so as to move in conjunction with a rotation of the sensor housing. The drive gear and driven gear engage with each other in a condition where a rotational track surface of the drive gear and rotational track surface of the driven gear intersect at a predetermined angle. As a result, an inertial body supporting surface serving as a sensor reference plane can be accurately maintained horizontally even at an arbitrary seatback recline angle, and thus the accuracy of the acceleration sensor can be improved.

A system for detecting improper usage of a seatbelt of a vehicle includes a vehicle seat having a seat cushion and a seat back. A shoulder belt and a lap belt are intended to restrain an occupant sitting on the vehicle seat. The system includes a sensor module associated with the shoulder belt and the lap belt. The sensor module generates signals indicative of at least one parameter associated with the vehicle seat, the shoulder belt, and the lap belt when the occupant is sitting on the vehicle seat. The system also includes a controller that receives the signals indicative of the at least one parameter associated with the seat back, the shoulder belt, and the lap belt. The controller analyzes the received one or more signals, and determines whether the seatbelt is being used improperly by the occupant, based on the analysis.

A driver condition estimation device includes an estimation unit configured to trigger an event that a webbing of a seat belt device is retracted, and to estimate a condition of a driver based on an amount of retraction of the webbing in the event.

The invention relates to a sensor (310), in particular for triggering a vehicle safety device (301), having a movable inertia body (350) which is movable relative to a carrier element (340) of the sensor (310), wherein the inertia body (350) is moved by inertia in relation to the carrier element (340) in the event of an abrupt change in speed or an inclination of the sensor (310) beyond a predetermined extent, and is brought from its inoperative position into its triggering position, through which a triggering position of the sensor (310) is brought about. According to the invention, it is provided that the sensor (310) is provided with a deactivation device (700) which is suitable, in its deactivating state, to force the inoperative position of the inertia body (350).

The vehicle system includes an output device, a plurality of rear seats, a plurality of belt buckle sensors provided on each of the plurality of rear seats, a plurality of seat belt reminder (SBR) sensors provided on each of the plurality of rear seats, and a controller. The controller is configured to determine one rear seat on which a passenger or an object having a weight equal to or less than a predetermined weight is located based on an output value of the SBR sensor, determine whether a seat belt corresponding to the determined rear seat is worn based on an output value of the belt buckle sensor, and control the output device to output a warning message when the vehicle is turned off and a door of the rear seat is not opened or closed in a state in which the seat belt is worn.
