A vehicle occupant position sensor is mounted on the front of an airbag which is deployed toward a vehicle occupant. The sensor comprises a capacitance sensor constructed by rendering portions of the airbag which face the vehicle occupant conductive. The airbag on which the sensor is placed is also constructed to allow venting of the airbag before it is fully deployed. The distance between the sensor and the vehicle occupant is continually determined with respect to the sensor. The output of the capacitive sensor is processed by a control system and is used to predict the interaction between the airbag and the vehicle passenger and to cause the airbag to be vented if that interaction is predicted to be more harmful than beneficial to the vehicle occupant. A system which prevents airbag venting once the airbag is inflated or nearly inflated can also be employed.

Airbag with bag mounted sensor

A system for detecting the position of a seat within an automobile in which a selected number of discrete sensors S is used to detect (2xS) seat positions. This is accomplished by using an actuator which, when positioned over three sensors, activates three sensors and when positioned over two sensors, activates both sensors and when positioned over a single sensor, activates only the single sensor. A simple algorithm or logic determines position by the rule that, if a single sensor is activated the seat is positioned over the single sensor, but if two sensors are activated, the seat is positioned between those two sensors, and if none of the sensors is activated, the seat is not positioned over any of those sensors.
