A vehicle seat assembly includes a vehicle seat, a first retractable restraint system for the vehicle seat and a second retractable restraint system for the vehicle seat. The first restraint system is in the form of a retractable, three-point shoulder harness. The second restraint system includes a first strap designed to resiliently retract onto a first take-up reel located within the back rest of the vehicle seat, a second strap designed to resiliently retract onto a second take-up reel located within the back rest of the vehicle seat, and a buckle assembly located within the seat support of the vehicle seat which is designed to lockably receive a tongue affixed onto each of the first and second straps. In operation, the first and second retractable restraint systems operate independently of one another and provide the vehicle seat with two separate means for safely restraining a passenger therein, the first restraint system being designed to restrain passengers in the vehicle seat who weigh over 100 pounds and the second restraint system being designed to restrain passengers in the vehicle seat who weigh between 40 and 100 pounds.
