Abstract: A headrest is provided including an upper pillow section that configures a front side of an upper portion of the headrest, and a lower pillow section that configures a front side of a lower portion of the headrest. A front-rear position of the lower pillow section with respect to the upper pillow section is adjustable by swinging the lower pillow section about a shaft extending along a seat width direction at an upper edge side of the lower pillow section, and a protrusion amount by which respective seat width direction side portions of the lower pillow section protrude toward a seat front side being adjustable with respect to a seat width direction intermediate portion of the lower pillow section by swinging the two seat width direction side portions about a shaft extending in a seat vertical direction.

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.

Abstract: A vehicle seat includes a seat cushion, and a seat back that is connected to the seat cushion in a manner so as to be able to be raised and reclined. The seat back has a cushion that supports an occupant. The cushion includes a main portion that opposes a torso of the occupant, and a side portion that is arranged on an outside of the main portion in a seat with direction and that protrudes toward a seating side of the seat back. The side portion includes a first portion that is arranged on an upper portion of the side portion and opposes a shoulder of the occupant when the seat hack is in an upright position, and a second portion that forms the side portion other than the first portion. The first portion and the main portion are configured to elastically compress easier than the second portion.
