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.

A device (10) for detecting a belted condition for a seat belt system (12) of a motor vehicle (14) is presented. The device (10) comprises at least one transceiver (24) for electromagnetic waves as well as a transponder (28) and a controller (30). The first transceiver (24) is disposed, when viewed in the vehicle longitudinal direction (L), in front of or behind the sitting position of a vehicle occupant (16) and is connected to the controller (30) so as to transmit signals. The transponder (28) is arranged on webbing of the seat belt system (12) associated with the vehicle seat (19) and is configured to receive and automatically respond to scanning signals of the transceiver (24). The controller (30) is configured to detect, based on output signals of the first transceiver (24), whether the vehicle occupant (16) has correctly fastened the seat belt (18). Furthermore, a method for detecting a belted condition is suggested.

An occupant restraint belt webbing forms an occupant restraint belt to restrain a vehicle occupant, and includes a plurality of warp yarns and a plurality of weft yarns. The plurality of warp yarns and the plurality of weft yarns are woven so as to extend orthogonally to each other. The warp yarns include an infrared light absorption yarn, and a thickness of the infrared light absorption yarn differs from a thickness of each yarn of the plurality of wrap yarns other than the infrared light absorption yarn.

Apparatus for detecting a proper wearing status of a safety belt of a safety belt assembly in a motor vehicle includes a sensor device which is at least partially disposed in or on the safety belt and configured to output a sensor value as a function of a dependency on a disposition of the safety belt. An evaluation device determines in response to the sensor value output by the sensor device, whether an occupant of the motor vehicle properly wears the safety belt.

According to one embodiments, a wearing detection apparatus includes a restraint device, an imaging device, a control unit, and an output device. The restraint device is to restrain a passenger seated in a seat, and includes a strap an exposed area of which changes when the strap is being worn and not worn. The imaging device captures an image of the restraint device including the strap. The control unit detects from the image captured by the imaging device, a recognition image corresponding to a recognition member provided in an area that is exposed when the strap is worn. The output device outputs a result of detection of the recognition image.

A system for detecting seatbelt routing includes: a state module configured to, based on a series of images over a period of time from a camera of a vehicle facing a seat, determine and output a routing state of a seatbelt of the seat; and a remediation module configured to, based on the routing state of the seatbelt of the seat, selectively perform at least one remedial action.
