Airbag deployment control based on contact with occupant
First Claim
1. A method for controlling outflow of fluid from a vehicular airbag, comprising:
- deploying the airbag toward an occupant prior to or during an accident involving the vehicle;
thendetecting contact between the airbag and the occupant by means of a sensor system after the airbag has been deployed toward the occupant; and
controlling outflow of fluid from the airbag by means of an airbag fluid controller based on the detected contact between the airbag and the occupant by the sensor system.

Abstract
Method for controlling outflow of gas from an airbag includes deploying the airbag toward an occupant prior to or during an accident involving the vehicle, detecting contact between the airbag and the occupant by means of a sensor, and controlling outflow of gas from the airbag based on the detected contact. Contact between the airbag and the occupant may be detected by analyzing deceleration of the airbag, e.g., via an accelerometer arranged on a surface of the airbag, a pressure sensor arranged to sense the pressure in the airbag which is correlatable to the deceleration of the airbag and tension sensors arranged on tethers between opposed inner surfaces of the airbag. Outflow of fluid from the airbag may be controlled by arranging an exit control valve or vent in, on or in connection with the airbag and which is adjustable to provide variable outflows of gas from the airbag.

12. A system for controlling outflow of fluid from a vehicular airbag, comprising:
-
an airbag arranged to deploy toward an occupant prior to or during an accident involving the vehicle; a sensor system that detects contact between said airbag and the occupant; and a fluid outflow control system that controls outflow of fluid from said airbag based on the contact between said airbag and the occupant as detected by said sensor system. - View Dependent Claims (13, 14, 15, 16, 17, 24, 25)

18. A method for controlling deployment of a vehicular airbag, comprising:
-
detecting an accident involving the vehicle by means of a sensor system; deploying the airbag toward an occupant prior to or during the accident at initial deployment conditions by means of an airbag deployment system; detecting contact between the airbag and the occupant by means of a sensor system; determining adjusted deployment conditions based on the detected contact by means of a processor; and adjusting the deployment of the airbag via the airbag deployment system to provide the adjusted deployment conditions. - View Dependent Claims (19, 20, 26, 27)
