A method for sensing the webbing extension of a seat belt (12) from a webbing retractor (10) of a vehicle includes sensing the position of the magnet (18) by means of the magnetic field sensor (20) by the control unit (22). The control unit (22) detects when the magnet (18) has completed a full turn. The control unit (22) deposits the number of the full turns in a memory (26). The control unit (22) determines the webbing extension by way of number of the full turns and the position of the magnet (18). A webbing retractor (10) for a seat belt (12) has a magnet (18).

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.

In the webbing winding device, the rotation of the output shaft of the motor is transmitted to the spool via the first gear train. In this state, when the rotation speed of the spool decreases and the rotation of the slider base of the first clutch decreases, the coupling pawl of the second clutch is pressed by the slider provided on the slider base to mesh with the ratchet gear, and the rotation of the output shaft of the motor is transmitted to the spool via the second gear train.

A protection system comprises at least one inflatable safety structure, each associated with a gas generator that can be activated by an external command, wherein the external command comprises an electrical signal from an automated system that is responsible for the critical safety functions of a vehicle, corresponding to predictive information about an impact. The gas generator is configured to generate a gas over a time period such that the total inflation time of the inflatable structure is greater than 50 milliseconds. The inflatable structure may be waterproof.
