1. A method for modeling an inflatable supplemental restraint device for a vehicle, comprising the steps of:

  • modeling the restraint device in a fully inflated state, using a finite element model;

    reconfiguring the modeled restraint device from a fully inflated to a fully deflated and flattened configuration using data from the model of the fully inflated state in the implicit finite element model; and

    using the results corresponding to the fully deflated and flattened configuration, including the finite element mesh data and the geometry data corresponding to the fully deflated and flattened configuration, as an input to a finite element model to simulate folding of the restraint device from a fully deflated and flattened configuration to a folded configuration.
