Abstract:
1. A headrest to be attached to a seat back of a seat for an automobile, comprising: a headrest body; and an attachment member adapted to be attached to the seat back to allow the headrest body to be moved in an upward-downward direction with respect to the seat back when the seat back is in a standing posture while allowing the headrest body to be rotated about a pivot shaft so as to move a lower end of the headrest body in a frontward-rearward direction of the automobile, wherein the headrest body has an expanded portion formed on a rear portion thereof to expand rearwardly, the expanded portion being formed in a shape so that a distance between a surface of the expanded portion and the pivot shaft gradually decreases toward an upper edge of the expanded portion, the expanded portion including a lower surface and a rear inclined surface extending from the lower surface while curving rearwardly and upwardly, wherein the expanded portion is arranged to be opposed to an upper surface of the seat back when the seat back is in the standing posture, and a contact position between the expanded portion and the seatback is frontward of the pivot shaft when the seat back is in the standing posture, and wherein the headrest body is configured to be rotated so that a lower end of the headrest body is moved frontward due to a contact between at least a part of a region extending from the lower surface to the rear inclined surface of the expanded portion and a region including at least a front end of the upper surface of the seat back in a position frontward of the pivot shaft during an operation of pushing the headrest body downwardly in the standing posture of the seat back.
