A finite element model for the aviation seat/seat belt is established and validated based on typical triple passenger seats, and the influence of seat belt parameters such as seat belt anchor position, seat belt stiffness and seat belt type on the dynamic response of the seat system is invistigated. Under horizontal impact loading, the position of belt’s anchor has significant effect on the occupant’s motion trajectory and loads on seat legs. The load on the rear left leg and front left leg in the Z direction decreases with the increase of the seat belt angle. Meanwhile, the position of the belt’s anchor has small influence on the seat belt load. Seat belt stiffness has significant effect on the occupant’s motion trajectory, seat belt load and seat leg load. As the stiffness increases, the seat belt load increases, while the occupant's forward movements and seat leg load decrease. Besides, compared with the two-point seat belt, the Y-belt restraint the occupant better, and can reduce the maximum displacement of the head by 63 mm in the X direction. Y-belts can be installed in the front seats to decrease the front row seat setback distance.
