Abstract
A booster seat has a seat member (14) and armrests (12a, 13a), and the distance between the armrests (12a, 13a) can be automatically changed according to the height of the support portion (14a) of the seat member (14). The armrests (12a, 13a) are formed on side members (12, 13) extended on the opposite sides of the support portion (14a) of the seat member 14 on a base (11) mounted on a seat of a vehicle. Tapered, wedge-shaped blocks (17, 18) are arranged on the inner side surfaces of the side members (12, 13) so as to extend toward a middle portion of the support portion (14a). When the side members (12, 13) and the wedge-shaped blocks (17, 18) are moved on the base (11) in directions along the width of the support portion (14a), the seat member (14) is moved vertically relative to the base (11) by the cooperative action of the upper surfaces (17a, 18a) of the wedge-shaped blocks (17, 18) and the bottom surface (14b) of the seat member (14) and, at the same time, the distance between the armrests (12a, 13a) is adjusted.
