Claims

[Claim for Utility Model Registration] Using a guide rail that extends in the width direction of the vehicle and is curved downwardly as a guide, when receiving lateral G that occurs during a turn, the outer side of the seating surface when turning. In a vehicle seat device that is swung so that a portion of the guide rail is high and a portion on the inner side of the turn is low, the amount of change in lateral G is reduced by partially varying the radius of curvature of the guide rail in the longitudinal direction of the guide rail. A vehicle seat device characterized in that the ratio of the amount of change in the seat swing angle relative to the lateral G is set to be small when the lateral G is small and to be large when the lateral G is large.
