ABSTRACT:
The invention relates to a fabric part for arranging in the interior of a gas bag of a vehicle occupant restraint system.
BACKGROUND OF THE INVENTION
Such fabric parts are used, more particularly, to deflect in a desired direction the flow of hot compressed gas entering the interior of the gas bag following activation of an inflator. This prevents the hot compressed gas from directly impinging the wall of the gas bag and damaging it. In addition, steering the deflection of the flow of compressed gas enables the deployment response of the gas bag to be greatly influenced, e.g. that the gas bag first deploys laterally before then deploying in the direction of the vehicle occupant towards the end of deployment, depending on the inflow direction of the compressed gas into the gas bag.
BRIEF DESCRIPTION OF THE INVENTION
The invention provides a fabric part which may be arranged in the interior of the gas bag and excels by being particularly simple to fabricate. The fabric part, when spread out flat, comprises a generally rectangular middle section with shorter and longer outer edges as well as four fastening sections. The fastening sections are disposed at the shorter outer edges of the middle section such that each thereof extends starting from the longer outer edges along the shorter outer edges toward a longitudinal centerline of the middle section. Each of the fastening sections ends at a distance away from the longitudinal centerline, thus enabling the fabric part to materialize from a flat blank. Since this blank is rectangular, no waste materializes in cutting it to size.
