Safety restraint design system and methodology
First Claim
1. A system for controlling the design of a safety restraint system so that a predetermined desired level of an occupant'"'"'s response is produced, the controller comprising:
- a multi-domain occupant restraint factor response model, the model interrelating at least one predetermined restraint configuration with the occupant response, the restraint configuration having a first set off variable restraint control parameters which are indicative of an first set of adjustable control values of at least one component of a safety restraint system, said model being configured to simulate a crash event by conducting a series of calculations which describe the event over a discrete time domain;
a solver module configured to receive data from the occupant restraint factor response model at a predetermined interval which is coupled to the occupant restraint model so as to generates a second set of restraint control parameters which are indicative of an second set of adjustable control values that are then passed back to multi-domain restraint simulation code; and
whereby the safety restraint design is controlled based upon the determined second level of the restraint factors which produces the desired level of the safety response.

Abstract
Disclosed is a safety restraint design controller for controlling the design of a safety restraint system so that a predetermined desired level of an occupant'"'"'s response is produced. The controller has a database for storing a occupant restraint factor response model. The model interrelates at least one predetermined restraint factor with the occupant response; the restraint factors having a level which is indicative of setting values for controlling the safety restraint design. A database engine connected to the database determines a level for the occupant response based upon the model and upon a first level of the restraint factors. A solver is connected to the database engine for determining a second level of the restraint factors which produces the desired level of the occupant response based upon the desired level of the occupant response from the database engine whereby the safety restraint design is controlled based upon the determined second level of the restraint factors which produces the desired level of the safety response.

8. A computer implemented method for designing a safety restraint system so that a predetermined desired level of occupant responses produced, comprising the steps of:
-
storing an occupant restraint factor response model in a computer storage medium, the model interrelating at least one predetermined restraint factor with the occupant response, the restraint factors having a level which is indicative of setting values for response output for components within the design of the restraint system;
determining a level for the occupant response based upon the model and upon a first level of the restraint factors;
determining a second level of the restraint factors which produces the desired level of the occupant response based upon the determined level of the occupant response;
providing a solver configured to receive signals from the occupant response model and determining if changes should be made to the response factors are needed; and
a coupling software operatively disposed between the solver and the occupant restraint response model. - View Dependent Claims (9, 10, 11)
