A vehicle seat comprising:

• a seat cushion configured to support the buttocks of an occupant;
• a pair of left and right side frames that each configure part of a framework of the seat cushion and that are spaced apart from each other in a seat width direction;
• a webbing that includes a lap webbing portion configured to pass across the waist of the occupant seated on the seat cushion, in the seat width direction;
• a buckle configured to engage with a tongue through which the webbing is inserted;
• a first link bracket that is supported by one of the side frames so as to be tiltable about an axial direction running in the seat width direction and that is connected to one side end portion of the webbing;
• a second link bracket that is supported by the other of the side frames so as to be tiltable about the same axis as the tilt axis of the first link bracket and that is connected to an opposite side of the buckle to the side with which the tongue engages, and that is tilted toward a seat upper side together with the first link bracket by the waist of the occupant pulling on the lap webbing portion during sudden vehicle deceleration;
• and
• a restriction member that links the first link bracket and the second link bracket together in the seat width direction, that is moved toward the seat upper side by tilting of the first link bracket and the second link bracket toward the seat upper side, and that restricts movement of the occupant seated on the seat cushion toward a seat front side.
