Abstract

An air bag safety system for cushioning restraint of a vehicle occupant during an impact event. The safety system includes a variable depth inflatable air bag cushion having at least one vent opening. A cover element of substantially pliable material is located in overlying relation to the vent opening. The cover element is selectively displaceable relative to the vent opening in response to the inflation depth of the air bag cushion so as to adjust venting characteristics.

Description

TECHNICAL FIELD [0001] This invention relates to an air bag assembly, and more articularly to an air bag assembly including an inflatable air bag cushion and one or more selectively actuated vents across the surface of the air bag cushion. The vents are selectively actuated in conjunction with control of the inflated profile of the air bag cushion such that venting is properly matched to the inflated profile characteristics of the air bag cushion. The venting characteristics of the air bag cushion and the profile of the air bag cushion may be controlled by the selective adjustment of tethering elements based upon the measured size and / or position of the vehicle occupant to be protected. BACKGROUND OF THE INVENTION [0002] It is well known to provide an air bag assembly including an inflatable air bag cushion for protecting the occupant of a transportation vehicle. In an automotive vehicle such air bag assemblies are typically located within the hub of the steering wheel and in a rece...
