The invention relates to a belt retractor comprising a signal transmitter ring (6) for a magnetic sensor (34). comprising a hub (14) which is connected to the belt reel in a rotationally fixed manner and comprising a signal transmitter portion (20) exhibiting periodically varying material properties when viewed in the circumferential direction, wherein the signal transmitter portion includes a stop (30) by which it abuts against a contact surface (32) associated therewith, and comprising a spring portion (18) acting on the signal transmitter portion relative to the hub so that the stop abuts against the contact surface.

System and method for obtaining and recording information about cargo includes a frame defining a cargo-receivable compartment, a position determining system at least partly on the frame and that allows for determination of position of the frame, an identification system on the frame that obtains information about cargo when present in the compartment, a memory component that receives and records information about position and movement of the frame, and the obtained information about cargo when present in the compartment in association with a unique identification of the frame, and a communications system on the frame to enable communication of information to and from the memory component.

Systems and method are provided for controlling a vehicle. In one embodiment, a method for determining the state of a restraint system provided within a vehicle includes incorporating one or more marker components into a restraint system component located within the vehicle, then receiving sensor data associated with the position of one or more of the marker components. The method further includes determining, with a processor, a state of the restraint system based on the sensor data.

A retractor assembly includes a housing; a spool rotatably coupled to the housing and defining an axis; a webbing coiled about the spool; a disc in contact with the webbing and movable parallel to the axis; and a linear variable differential transformer including a core movable parallel to the axis with the disc.

a seat belt wearing encouragement apparatus includes a wearing state detecting unit to detect a wearing state of a seat belt; a wearing determination unit to determine whether the seat belt is worn, based on the wearing state; a vehicle speed detecting unit to detect a vehicle speed of the vehicle; a warning unit to warn the passenger; a warning command unit to issue a command to the warning unit to execute warning if the vehicle speed detecting unit has detected the vehicle speed exceeding a setting speed, and the wearing determination unit has determined that the seat belt is not being worn properly; and a vehicle speed limiting unit to limit the vehicle speed in a case where even after a predetermined time has elapsed since the warning was executed, the wearing determination unit still determines that the seat belt is not being worn properly.

The present disclosure relates to a method for controlling a time of activation of a restraint system in a vehicle, the vehicle comprising a seat belt associated to a seat, the restraint system being a reversible restraint system, the method comprising the steps of a) determining a current length (L) of pulled out seat belt, b) detecting a collision or an imminent collision involving the vehicle, c) predicting a time (T.sub.0) when the collision is predicted to affect a user of the seat belt, d) activating the reversible restraint system a selectable time period (.sub.1) before the time (T.sub.0) when the collision is predicted to affect the user of the seat belt, wherein a length of the selectable time period (.sub.1) is a function of the determined current length (L) of pulled out seat belt. The disclosure further relates to a safety arrangement of a vehicle.

A method and system for determining whether a seatbelt of a vehicle is fastened is provided. The system may be configured to detect markers on a seatbelt, engage seatbelt tensioners, and determine whether the markers have moved. The system may then be configured to determine whether the seatbelt is fastened based on movement of the markers.

A computer that may be programmed to: in response to receiving an indication that a vehicle is approaching a geofence boundary, retract slack in a webbing associated with a seat in the vehicle by actuating a seatbelt retractor; then receive measurement data from one or more sensors associated with the seat; using the data, determine whether an occupant occupies the seat; and when no occupant occupies the seat, then transmit an instruction to stop the vehicle.

A seatbelt assembly includes webbing elongated along a length, a clip slidable along the length of the webbing, an indicator extending along the length of the webbing, and a sensor coupled to the clip and sensitive to the indicator. The seatbelt assembly measures a length of a lap band stretched across an occupant. Safety features may be tailored to the body type of the occupant.

A plus-two-point belt system is disclosed. The plus-two-point belt system includes a longitudinal webbing anchored at a first end to a seat and fixed at a second end to a retractor. The webbing is extendable from the retractor to allow an occupant to slip their arm under the webbing to provide a supplemental restraint. The webbing includes first and second portions where the second portion is retractably coiled on the retractor and the second portion has at least one conductive marker. A sensor is provided to sense the marker and a processor is provided to set an alarm when the marker is not detected.
