VEHICLE SEAT

A vehicle seat includes a seat main body and a hinge member. The seat main body is disposed in a state facing to a vehicle rear side. A seat back of the seat main body is attached to a vehicle body side vertical wall portion of a passenger compartment front portion. An end portion at the vehicle rear side of a seat cushion of the seat main body can be flipped up. One end portion of the hinge member is fixed to an end portion at the vehicle front side of the seat cushion and another end portion is rotatably coupled to a passenger compartment floor portion. The hinge member is provided with a weakened portion that, during a vehicle front collision in a state in which the seat main body is unfolded, plastically deforms and allows movement of the seat cushion toward the vehicle front side.
