PROBLEM TO BE SOLVED: To properly change a state in response to a physical constitution of an occupant, in a constitution where the state is changed when inputting a rear load to a vehicle.SOLUTION: A vehicle seat for changing a state when inputting a rear load to a vehicle, comprises a rotary member 20 for moving from an initial position by being accompanied by a change in the state and a locking pin 22 for restricting the movement of the rotary member 20. When the load applied to the vehicle seat from an occupant of the vehicle changes in response to a physical constitution and body weight of the occupant according to input of the rear load, when the rotary member 20 reaches a first position by moving from the initial position when the load is less than a predetermined value, the locking pin 22 detains the rotary member 20 in a first position. While, when the load is the predetermined value or more, the rotary member 20 escapes from movement restriction by the locking pin 22 after reaching the first position, and further moves toward a second position separated from the initial position more than the first position.SELECTED DRAWING: Figure 5 |
