Abstract
A passive seat belt system for an automotive vehicle has a webbing which takes a passenger restraining position or a passenger releasing position. Impact detecting means is provided to detect impact applied to the vehicle. Door state change detecting means is provided to detect change in closing and opening states of a vehicle door. When the change is detected, signal output regulating means selectively outputs closing and opening signals for a predetermined time. Additionally, the signal output regulating means is adapted to prohibit the closing and opening signals from being output when the impact signal is output from the impact detecting means. Webbing driving means is provided to move the webbing to the passenger restraining and releasing positions respectively in response to the closing and opening signals output from the signal output regulating means. The system allows vehicle escape in an emergency, if the door is opened.
