Who Should Use It?
A booster seat should be used by children who weigh at least 18 kg (40 lbs).
There is no age limit for using a booster seat, only a weight limit. It is therefore important to ensure that your child does not exceed the weight limit indicated on the seat.
Why?
A booster seat raises the child and allows a seat belt to be properly adjusted over the middle of the shoulder (on the collar bone) and on the hips.
Position of a Seat and Child in a Vehicle
The safest location in a vehicle to place a booster seat is the rear seat.
If the back of the seat is low or does not have a headrest, a booster seat with a built-in backrest is required so that the child's head is supported in the event of a rear-end collision.
The vehicle's seat belt (lap and shoulder belts) is all that is required to hold the seat and child in place. No additional straps are necessary.
When the seat belt is buckled, it should come over the middle of the shoulder (on the collar bone) and on the hips. The collar bone and pelvic bones are among the body's strongest and must absorb the impact in the event of an accident.
Be especially careful in making sure the belt is adjusted properly if the child is wearing winter clothing. Make sure the belt lies across the pelvic bones and on the collarbone. When a seat belt is buckled, it should be snug and have no slack.
A seat belt should never be placed behind a child's back or under the arm because crash forces can cause serious injury to vital organs such as the heart and lungs.
