Abstract: An apparatus for restraining a mobility aid in the interior of a vehicle includes two or more retractor spools contained within a common housing. The retractor spools carry flexible webbed belts, and are operated by common actuator mechanism having a direct mechanical attachment to the spools. The various elements of the apparatus are contained within a common housing which is easily mounted to a bulkhead or under a foldable seat. A third retractor is mounted in opposition permitting both the front and rear of the mobility aid to be easily secured by the occupant of the mobility aid without assistance of the operator of the vehicle. The operative portions of the retractor are designed to be positioned so as not to present an obstacle to other users of the vehicle in which the apparatus may be installed. A timing mechanism is provided for at least one of the retractor spools to allow at least one of the retractor spools to be freely manipulated during a predetermined time interval.
