Abstract
A restraint system and method is adaptive to the size of the occupant, and adapts both pretensioning and load limitation characteristics to the occupant. The adaptive restraint system generally includes a retractor, a belt anchorage pretensioner, and a retractor pretensioner. The system is operable in at least a first mode and a second mode. In the first mode, both the belt anchorage pretensioner and the retractor pretensioner are activated when the occupant is estimated to be above a predetermined size, thereby providing a first load limitation characteristic. In the second mode, only the belt anchorage pretensioner is activated when the occupant is estimated to be at or below the predetermined size, thereby providing a second load limitation characteristic.
