A vehicle seat assembly includes a frame member, a seat bottom and a buckle assembly. The seat bottom is coupled to the frame member for pivotal movement within a movement range defined between a seating position and a retracted position in which the seat bottom angles upward. The buckle assembly includes a buckle arm and a seatbelt buckle. The buckle arm includes a first end coupled to the frame member for pivotal movement between a seating position corresponding to the seating position of the seat bottom and a retracted position corresponding to the retracted position of the seat bottom. The seatbelt buckle is coupled to a second end of the buckle arm. The buckle assembly is configured to pivot in response to pivoting movement of the seat bottom with the majority of the seatbelt buckle being maintained within the cutout throughout all of the movement range of the seat bottom.
