Abstract
Abstract A child seat is provided wherein the distance between shoulder belts can be adjusted in accordance with the adjustment of the height of a seat plate. The seat plate formed of a front seat plate and a rear seat plate is supported to a seat body attached to a seat back such that the seat plate can be moved up and down. The seat plate is supported by a front link and a rear link. As the seat plate is moved up and down, an interlocking member is also moved up and down so that shoulder belt guides engaged with elongated holes of the interlocking member slide closer to and apart from each other, thereby adjusting the distance between the shoulder belts.
