Patent ID: 8840140

Claim:
An airbag module for a motor vehicle, comprising: an airbag cushion including at least one panel surrounding an inflatable interior portion; an inflator configured to provide inflation gas for inflating the airbag cushion; and an inflation control device located in the interior portion of the airbag cushion, wherein the inflation control device includes a first member coupled to a coupling member, and wherein the first member is connected to the at least one panel; wherein the inflation control device is configured to allow the airbag cushion to inflate generally unrestrained until each of the first and coupling members are subjected to a tensile force; wherein the inflation control device is configured to reduce a rate at which the airbag cushion expands after the first and coupling members are subjected to the tensile forces; wherein the first member includes a plurality of apertures, and the coupling member is elongated and extends through the plurality of apertures; and wherein when a sufficient tensile force is applied to the first member due to the inflation of the airbag cushion, the position of the coupling member relative to the plurality of apertures of the first member changes and the resulting friction between the first member and the coupling member reduces the rate at which the airbag cushion expands.
