Filed:

May 27, 2008

Appl. No.:

12/154750

Inventors:

Scott Jackson - Centerville UT, US
Robert E. Lewis - West Haven UT, US
Kevin Smith - Bountiful UT, US
Gary Smith - Layton UT, US
Gregory J. Lang - South Ogden UT, US

Assignee:

Autoliv ASP, Inc. - Ogden UT

International Classification:

B60R 21/26

US Classification:

280736

Abstract:

An airbag inflator that includes a pyrotechnic material capable of producing a quantity of gas during deployment. The inflator also includes a filter. The filter may be an expanded metal filter that is wrapped about the pyrotechnic material. When this filter is wrapped about the pyrotechnic material, the filter forms a plurality of layers having holes that are a different size. This filter also includes a first set of barriers and a second set of barriers that are positioned exterior of the first set of barriers, the second set of barriers being offset from the first set of barriers. Gas passing through the filter will encounter the first set of barriers, be re-directed, encounter the second set of barriers, be re-directed, and then flow out of the filter.

Morton International, Inc.

International Classification:

B60R 2126

US Classification:

280741

Abstract:

Featured in an air bag inflator in respect of which, during assembly, there is a requirement for the ignition train to be installed last, along with a need to hermetically seal both the gas generant material and the ignition train from the environment, is the use of two independent pressure vessels, one of which contains the gas generant material, filtering and cooling elements and a separate pressure vessel having an open end into which is inserted a squib capable of being activated by an appropriate signal and which contains all of the primary and secondary ignition pyrotechnics, the open end of the pressure vessel being closed by the presence of the squib, the pressure vessel having a necked region in its length which forms a plenum chamber when mated to the second pressure vessel containing the gas generant material, etc. , the circumferance of the pressure vessel containing the squib being ported in such a way as to allow the squib, when fired, to shear out, the effluent of the squib being transferred out through the breaches created at the ported locations into the plenum, the effluent in the plenum then breaching similar ports incorporated into the second pressure vessel containing the gas generant material, the effluent then dispersing into the cavity of the second pressure vessel igniting the gas generant material.

International Classification:

B29C 4120

US Classification:

264254

Abstract:

A flexible sensor, such as a membrane switch, is molded into a plastic automotive panel by a low temperature, low pressure, method which avoids damage to the switch while insuring its placement at a desired depth below the surface of the panel. This is achieved by a process which includes a first step of spraying a mold with a rapid gelling liquid plastic to a preselected thickness. After the plastic has firmed, the sensor is placed thereon and is encapsulated by spraying with a second layer of the plastic. The resulting shell with the embedded sensor may then be provided with a backing, such as a plastic foam.
