A system for determining seatbelt routing. The system includes a seatbelt retractor, a guide loop, a seatbelt latchplate, a seatbelt buckle, a seatbelt buckle sensor, a first RFID tag, RFID reader, and a control module. The seatbelt retractor stores a length of seatbelt webbing. The guide loop changes a routing direction of the seatbelt webbing. The seatbelt latchplate is engaged with the seatbelt webbing. The seatbelt buckle is secured to the motor vehicle and engages the latchplate. The seatbelt buckle sensor for detects the presence of the latchplate in the seatbelt buckle. The first RFID tag is attached to the seatbelt webbing of the seatbelt. The RFID reader detects the presence of the first RFID tag. The control module determines the seatbelt routing based on whether the seatbelt is buckled and the detection of the first RFID tag by the RFID reader.

An alert device alerts a driver sitting on a driver's seat in a vehicle by winding a seat belt on the driver's seat with a retractor. The alert device includes a seat position information acquisition unit configured to acquire seat position information relating to a position of the driver's seat, a height estimation unit configured to calculate art estimated height that is an estimated value of the driver's height based on the seat position information, a winding strength setting unit configured to set a winding strength that is a strength for winding the seat belt with the retractor based on the estimated height, and a retractor control unit configured to operate the retractor to wind the seat belt with the winding strength.

In one embodiment, a system of detecting seat belt operation in a vehicle includes at least one light source configured to emit a predetermined wavelength of light onto structures within the vehicle, wherein at least one of the structures is a passenger seat belt assembly having a pattern that reflects the predetermined wavelength at a preferred luminance. At least one 3-D time of flight camera is positioned in the vehicle to receive reflected light from the structures in the vehicle and provide images of the structures that distinguish the preferred luminance of the pattern from other structures in the vehicle. A computer processor connected to computer memory and the camera includes computer readable instructions causing the processor to reconstruct 3-D information in regard to respective images of the structures and calculate a depth measurement of the distance of the reflective pattern on the passenger seat belt assembly from the camera.

A vehicle occupant restraint device includes a three point seatbelt device that includes shoulder webbing running from one seat width direction end side of an upper section a seatback toward a buckle at another seat width direction end side of a lower section of the seatback, a shoulder webbing anchor that is provided on the one seat width direction end side of the upper section of the seatback, and through which the shoulder webbing is inserted, and a mover device that moves the shoulder webbing anchor toward a seat width direction outer side of the seatback when the seatback, which is configured so as to be capable of reclining from an upright state, has been reclined by at least a predetermined angle or greater with respect to a vertical direction.

A guide ring sensor has a fixing seat, a guide ring, an elastic member, and a sensing element. The guide ring is pivoted on the fixing seat by a positioning member. The elastic member is mounted on the body of the fixing seat, is connected to the guide ring, and provides resilience to the guide ring. The sensing element is mounted on the fixing seat to detect a pivoting angle change of the guide ring and generate a signal corresponding to the pivoting angle change of the guide ring. The sensing element may detect whether a webbing is correctly fastened or not by the pivoting angle change of the guide ring.

A seat belt routing sensing system for a seat belt of a vehicle is provided. The seat belt includes a latch plate. The seat belt routing sensing system includes a seat belt buckle mounting assembly and a sensor. The seat belt buckle mounting assembly includes a first bracket or a first strap. The first bracket or the first strap is configured to connect to a seat belt buckle. The sensor is attached directly or indirectly to the first bracket, the first strap, or the seat belt buckle and is configured to detect changes in a parameter. The changes are indicative of (i) at least one of a bending moment, a force, an angular position, or an angular movement of the first bracket or first strap, and (ii) routing of the seat belt.

Systems, vehicles, and methods for seatbelt assistance. A system may include a sensor. The sensor may be configured to detect a physical property of a user sitting on a seat. The system may further include a motor. The motor may be configured to extend a seatbelt part towards a body center of the user. The system may further include an electronic control unit (ECU). The ECU may be coupled to the sensor and the motor. The ECU may be configured to receive the detected physical property of the user. The ECU may be further configured to prompt the motor to extend the seatbelt part towards the body center of the user based on the detected physical property of the user.

A system to locate seat controls and belt buckles includes a vehicle having at least one seat. A seat belt system is provided with the at least one seat having a seat belt, a belt latch and a seat belt buckle. A haptic device is provided with the seat belt system, the haptic device generating a haptic signal.

The techniques of this disclosure relate to a vehicle occupancy-monitoring system. The system includes a controller circuit that receives occupant data from an occupancy-monitoring sensor of a vehicle. The controller circuit determines an occupancy status of respective seats in a cabin of the vehicle based on the occupancy-monitoring sensor. The controller circuit indicates the occupancy status of the respective seats on a display located in a field of view of occupants of the vehicle. The display is integral to one of a roof light module, a door panel, or a headliner of the cabin. The system can improve passenger safety by alerting the operator and other occupants about the occupancy status of the passengers.

A system that determines a condition of wearing of a seat belt, including: a marker provided on at least a part of the seat belt; an image capture processing unit that emits electromagnetic waves of the prescribed wavelength band toward a predetermined range and that creates an image indicating intensity distribution of electromagnetic waves of the prescribed wavelength band, based on reflected waves reflected in the predetermined range; a shape estimating unit that estimates a shape of an occupant based on the image, detects the marker from the image, and estimates a shape of the seat belt based on the marker detected; and a determining unit that determines the condition of wearing of the seat belt by the occupant, based on a positional relationship between the occupant and the seat belt.
