Patent 7748730 was granted and assigned to Takata Corporation on July, 2010 by the United States Patent and Trademark Office.
Deployment performance of an airbag may be improved by improving an air tightness of an leg airbag system that includes a knee airbag for restraining occupant's legs and a gas generator that generates a jet of gas to inflate the knee airbag. An end of the gas generator is connected to a gas generator ignition control cable and passes through an insertion opening. The insertion opening has an area smaller than a cross section area of the end of the gas generator.
