A child safety seat, sometimes called a infant safety seat, child restraint system, child seat, baby seat, car seat, or a booster seat, is a seat designed specifically to protect children from injury or death during vehicle collisions. Most commonly these seats are purchased and installed by car owners, but car manufacturers may integrate them directly into their vehicle's design and generally are required to provide anchors and ensure seat belt compatibility. Many jurisdictions require children defined by age, weight, and/or height to use a government-approved child safety seat when riding in a vehicle. Child safety seats provide passive restraints and must be properly used to be effective. However, research indicates that many child safety restraints are often not installed or used properly. To tackle this negative trend, health officials and child safety experts produce child safety videos to teach proper car seat installation to parents and caregivers.
