Abstract
A housing for storing an inflatable airbag includes a first portion and a second portion that cooperate to at least partially define a chamber for storing the inflatable airbag. A hinge portion connects the first portion to the second portion such that the second portion is pivotable about the hinge portion from a closed position for retaining the inflatable airbag within the chamber to an open position for deployment of the inflatable airbag from the chamber. A sacrificial seam connects the first portion and the second portion when the inflatable airbag is stored within the chamber. The sacrificial seam includes a plurality of connection members breakable in response to a pressure from within the chamber from initial inflation of the inflatable airbag. The connection members each extend across the sacrificial seam in a first direction between the first and second portions of the housing and are configured to have a predetermined failure area adjacent one of the first portion and the second portion.
