Airbag deployment trajectory control mechanism and method
First Claim
1. A passive restraint system, the system comprising:
- an airbag that is capable of deploying upon impact to restrain a body of at least one occupant;
at least one trajectory control tube adhered to the airbag, the at least one trajectory control tube capable of guiding a deployment trajectory of the airbag;
a compartment that initially houses the airbag and the at least one trajectory control tube, wherein the compartment is configured to be breached by inflation of the at least one trajectory control tube and/or inflation of the airbag; and
a diffuser plate having a first set of holes configured to channel gas to the airbag and having a second set of holes configured to channel gas to the at least one trajectory control tube, wherein a cross-sectional area of the first set of holes is smaller than a cross-sectional area of the second set of holes.

Abstract
A system and method of inflating an airbag and trajectory control tube are disclosed. The system and method include detecting application of a force at at least one of a plurality of sensors, initiating an inflation system to cause inflation of the airbag and the trajectory control tube responsive to the detecting, inflating the trajectory control tube based on the initiating, inflating the airbag, and breaching the airbag and the trajectory control tube compartment. The system and method include guiding the airbag deployment trajectory via the trajectory control tube guides the airbag deployment trajectory. The system and method include the guiding occurs as the airbag begins to inflate, as the airbag inflates, after the airbag has inflated or before the airbag inflates.
