Abstract
An inflatable curtain for protecting the occupants of a vehicle during a collision is provided. The inflatable curtain may include an inflatable portion. The inflatable portion may include a plurality of inflation chambers. The inflatable curtain may also include a non-inflatable portion. The non-inflatable portion may include one or more expandable sections disposed between adjacent inflation chambers. Deployment of the inflatable curtain typically causes the inflation chambers to contract in a horizontal direction. Deployment of the inflatable curtain also causes each of the expandable sections to expand horizontally, compensating for the contraction that occurs in the inflation chambers.
