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.

Description

Background technique [0001] Airbags and airbag systems have been known for many years. These systems are designed to inflate air bags toward the interior of the vehicle during a crash. Airbags are designed so that occupants come into contact with the airbag rather than the steering wheel, dashboard, side of the vehicle, and / or other parts of the vehicle. Air bags have been credited with saving many lives and are now standard on all new motor vehicles in the US, Europe and elsewhere around the world. [0002] In order to deploy airbags during a crash, inflators are often used. An inflator is a device capable of generating and / or delivering a quantity of inflation gas into an airbag during a crash. The inflow of gas to the airbag acts to deploy the airbag and position the inflated airbag within the vehicle interior. One type of inflator known in the art is the "pyrotechnic" inflator. This type of inflatable device includes a gas generant or other pyrotechnic material that i...
