PROBLEM TO BE SOLVED: To efficiently transmit a load input to a head rest during a rear end collision of a vehicle to a connection part in a seat back frame formed into a plate shape.SOLUTION: In a vehicle seat 10, a vertical wall bead 40 is integrally formed with a seat back frame 14. The vertical wall bead 40 is coupled to a bracket fixing part 20 and a connection part 46 to connect the bracket fixing part 20 with the connection part 46 in a seat vertical direction. The structure allows the vertical wall bead 40 to directly transmit a load, which is input from a head rest 60 to the bracket fixing part 20 during a rear end collision of a vehicle, to the connection part 46. Thus, in the seat back frame 14 formed into the plate shape, the collision load input to the head rest 60 during the rear end collision of the vehicle is efficiently transmitted to the connection part 46. |
