Abstract
A guide device for directing the deployment of an automotive air bag cushion toward the torso of an occupant by means of a tether which is folded and attached to itself at a number of locations by rupturable seams. As the air bag cushion deploys the truncated tether or tethers cause the cushion to rotate about a point where the cushion is attached to the canister thereby moving the cushion in a downward direction. The cushion is thereby moved into position in front of the occupant's torso more quickly than an air bag cushion equipped with a tether without tearseams.
