PROBLEM TO BE SOLVED: To suppress forward tilting of a seat back due to the operation of a pretensioner mechanism in a retractor-in-type seat. SOLUTION: In this vehicle seat system, a first seat belt device and a second seat belt device are provided with a first pretensioner mechanism and a second pretensioner mechanism, respectively. The first pretensioner mechanism and the second one are configured to operate the first retractor and the second one so that they pull in the first seat belt and the second one respectively when a collision is detected or predicted. In the first seat 1, a prescribed region receiving a pull-in load by the first seat belt when the first pretensioner mechanism is operated is reinforced more than a corresponding region in the second seat.
