Abstract:
A vehicle seat installed in a vehicle includes a seatback, a seat cushion, a seat frame, a movable part, a first spring, a second spring, and a preloading device. The first spring is capable of, when the movable part has shifted in a first direction, generating such an elastic force as causes the movable part to shift toward the neutral position. The second spring is capable of, when the movable part has shifted in a second direction, generating such an elastic force as causes the movable part to shift toward the neutral position. The preloading device is configured to change at least one of the elastic force exerted on the movable part by the first spring and the elastic force exerted on the movable part by the second spring.
