1. Field of the Invention
The present invention relates to a webbing supporting structure for supporting an occupant restraining webbing on a door for use in a seatbelt system for protecting an occupant.
2. Description of the Prior Art
There has been proposed a so-called passive seatbelt system in which one end of an occupant restraining webbing is secured to a door, whereby the webbing is caused to approach or recede from a vehicle seat in accordance with a door opening or closing action, so that the webbing can be automatically fastened to or unfastened from the occupant.
In this type of passive seatbelt system, when one end of a lap webbing for restraining a lap of the occupant is engaged with the door, the engaging portion is disposed as high as possible on the door, so that a space for actions of legs of the occupant can be secured when the door is opened. However, in this case, when the webbing is fastened to the occupant upon his closing the door, an anchor point of the lap webbing is disposed high, so that the lap webbing cannot satisfactorily display the occupant restraining performance, thereby presenting such disadvantages that the movement of the occupant in the direction of a collision may cause a secondary collision or damages may be caused to the abdominal region of the occupant.
