Device for stopping an airbag unfolding in a motor vehicle
First Claim
1. A system for stopping the deployment of an airbag in a vehicle, comprising a detector for detecting a position of said airbag with respect to an occupant of the vehicle and an airbag operating device, said detector being located on said airbag in an area which, on deployment of the airbag, is facing said occupant of the vehicle, said detector generating a position signal which is sent to said airbag operating device, and said airbag operating device stopping the deployment of the airbag when said position signal indicates a preset position of the airbag in relation to the occupant, wherein said detector is a contact detector for detecting a contact between the airbag and the occupant;
- wherein said contact detector is a force sensor, said force sensor detecting the pressure exerted by said airbag on said occupant; and
wherein the force sensor comprises at least two electrode structures located on said airbag at a certain distance from each other and a layer of semi-conducting material located in an active area of said force sensor, above said electrode structures, said layer of semi-conducting material being in close contact with said electrode structures, and said layer of semi-conducting material having an internal resistance varying with the deformation of said layer.

Abstract
A system for stopping the deployment of an airbag in a vehicle includes a detector for detecting a position of the airbag with respect to an occupant of the vehicle and an airbag operating device. The detector is located on the airbag in an area which, upon deployment of the airbag, is facing the occupant of the vehicle. The detector generates a position signal which is sent to the airbag operating device such that the airbag operating device stops the deployment of the airbag when the position signal indicates a predetermined position of the airbag in relation to the occupant.
