A passenger restraint system for a vehicle having a plurality of seats, each seat having a seatbelt, a retractor from which the seatbelt is extendable, and a receiver used to latch the seatbelt. Each retractor includes a first pneumatic locking element and a second pneumatic locking element for limiting movement of the seatbelt and each receiver includes a receiver pneumatic locking element for locking the seatbelt within the receiver. A controller controls the operation of a plurality of first valves for supplying air to the first pneumatic locking element of a corresponding one of the plurality of retractors, a second valve for supplying air to each of the second pneumatic locking element of the plurality of retractors, and a plurality of third valves for supplying air to the receiver pneumatic locking element of a corresponding one of the plurality of receivers. Control decisions may be made based upon feedback received from sensors within the receiver that sense a state of the seatbelt with respect to the receiver.
