a vehicle seat connected in a vehicle;
a seat belt assembly of the vehicle seat having an extending seat belt shoulder strap portion, a lap belt section, and a buckle releasably connected to a first buckle connector, the first buckle connector defining a first anchor connected by a first pin to a seat structural member, the first pin and the first buckle connector together displacing during a vehicle collision event from an initial first buckle connector position to a final first buckle connector position forward of the initial first buckle connector position to mitigate against a submarining motion of an occupant of the vehicle seat; and
the lap belt section fixed to a second buckle connector, the second buckle connector defining a second anchor connected by a second pin to the seat structural member, the second pin and the second buckle connector together displacing during the vehicle collision event from an initial second buckle connector position to a final second buckle connector position forward of the initial second buckle connector position,
wherein a seat cushion of the vehicle seat includes a first bolster and a second bolster opposed to the first bolster, the first bolster and the second bolster being individually angled inward toward each other and downward;
a first curved slot created in the first bolster; and
a first seat belt link connected to the first buckle connector and displaced within a first slot portion of the first curved slot initially in a forward direction until the first seat belt link reaches an inward curving portion of the first curved slot, after which the first buckle connector displaces both in an inward direction and a downward direction pulling the lap belt section downward into contact with the hip portion of the occupant of the vehicle seat.
