摘要：A vehicle occupant restraint system includes an airbag system and a seat beltharness with pretensioner and retractor mechanisms. Multiple sensors are mountedwithin the vehicle to measure and monitor various occupant and vehicle characteristics,which are entered into a central processing unit (CPU). These sensors include an occupant

presence sensor for determining whether there is an occupant present within the airbagdeployment area, a child seat sensor for determining whether a child seat is properlyinstalled in the airbag deployment area, and a seat belt usage sensor for determiningwhether a seat belt is in an engaged position. The occupant presence, child seat, and seatbelt usage sensors generate system modifier signals that can disable the airbag systemor seat belt mechanisms if certain predetermined conditions are not satisfied. Othersensors include an occupant weight sensor, an occupant proximity sensor for determiningoccupant position relative to the airbag deployment area, a crash severity sensor, and apre-crash sensor for providing vehicle speed and orientation characteristics prior to thecollision. All of these sensors provide input signals that are received by the CPU. The CPUprocesses these multiple input signals with a hizzy logic control system to generatemultiple output signals for controlling the airbag and seat belt mechanisms. The multipleoutput signals can include a multi-stage airbag inflation signal, a variable venting signal, aseat belt pretensioner signal, and a seat belt retractor signal.
