A method to manipulate the belt of a safety restraint system is outlined. The goal of the method is to design a controller that is able to minimize the maximum value of the chest acceleration, if the vehicle deceleration is a priori known. The method roughly consists of an system identification and controller design part. From the identification part, it can be concluded that the dynamical behavior from belt force to chest acceleration is linear, for small perturbations around an operating point in the original trajectory of the belt force. The assumed time invariancy of the dynamical behavior from belt force to chest acceleration does not have disturbing influence on the controller performance. From the controller design part, it may be concluded that simple linear and time invariant controllers may be used. In general, it may be concluded that although the operating points at which system identification is performed do not equal the operating points at which the controlled system operates, does not influence controller performance. The outlined method is applicable for the manipulation of the chest acceleration with the belt force for one crash test, dummy and vehicle only. Further research should focus on the applicability of the method for other cases, i.e. another dummy, crash and/or vehicle. Besides that, the constraints on the belt force have to be taken into account. Finally, the interaction between the belt, the airbag and the occupant has to be investigated, such that simultaneous manipulation of the belt and the airbag is possible.
