Abstract
A safety car seat for a child has a headrest vertical moving device, a shoulder belt position control device, a sleeping support position control device, a crotch belt position control device, a footrest step position control device and a moving device for changing the size or capacity of a support space for protecting the child. The shoulder belt position control device includes two holding plates that slide along two inclined elongated holes and are connected by two pivotable control arms to a control pin that slides along a vertical guide slot in the seat backrest. Upper portions of the shoulder belts pass through slit holes in the holding plates. The upper ends of the belts can be adjusted higher, wider apart and less inclined, or lower, closer together and more inclined.
