Child safety seats (sometimes referred to as an infant safety seat, a child restraint system, a restraining car seat, or ambiguously as car seats) are seats designed specifically to protect children from injury or death during collisions. Car manufacturers may integrate child safety seats directly into their vehicle's design. Most commonly, these seats are purchased and installed by consumers. Many regions 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, many child safety restraints in countries such as Canada and the United States are not 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. Baby car seats are legally required in many countries, including the United States, to safely transport children up to the age of 2 or more years in cars and other vehicles. Other car seats, also known as "booster seats," are required until the child is large enough to use an adult seat belt. This is usually, but not always, when the child is 1.45m (4 ft 9 in) tall. The child needs to meet five criteria before moving out of the booster seat, including the child's seating position, shoulder belt position, lap belt position, knee position, and ability to sit properly for the length of the trip. Generally, countries that regulate passenger safety have child safety laws that require a child to be restrained appropriately depending on their age and weight. These regulations and standards are often minimums, and with each graduation to the next kind of safety seat, there is a step down in the amount of protection a child has in a collision. Some countries, such as Australia and the United States, forbid rear-facing child seats in a front seat that has an airbag. A rear-facing infant restraint put in the front seat of a vehicle places an infant's head close to the airbag, which can cause severe head injuries or death if the airbag deploys. Some modern cars include a switch to disable the front passenger airbag for child-supporting seat use. In 2003, the American Academy of Pediatrics (AAP) suggested that infants “should spend minimal time in car seats (when not a passenger in a vehicle) or other seating that maintains supine positioning” to avoid developing positional plagiocephaly ("flat head syndrome").〔John Persing, MD, et al., American Academy of Pediatrics Committee on Practice and Ambulatory Medicine, Section on Plastic Surgery and Section on Neurological Surgery, "Prevention and Management of Positional Skull Deformities in Infants," Pediatrics 112, no. 1 (July 2003): 199-202.〕 In 1990, the ISO standard ISOFIX〔International Standard ISO 13216. Anchorages in vehicles and attachments to anchorages for child restraint systems. International Organization for Standardization, Geneva.〕 was launched in an attempt to provide a standard for fixing car seats into different makes of car. The standard now includes a top tether; the U.S. version of this system is called LATCH. Generally, the ISOFIX system can be used with Groups 0, 0+ and 1. In 2013, a new car seat regulation has been introduced: “i-Size” is the name of a new European safety regulation that affects car seats for children under 15 months of age. It came into effect in July 2013 and provides extra protection in several ways, most notably by providing rearward facing travel for children up to 15 months instead of 9 to 12 months, which the previous EU regulation advised. == History == Since the first car was manufactured and put on the market in the early 1900s, many modifications and adjustments have been implemented to protect those that drive and ride in motorized vehicles. Most restraints were put into place to protect adults without regard for young children. Though child seats were beginning to be manufactured in the early 1930s, their purpose was not the safety of children. The purpose was to act as booster seats to bring the child to a height easier for the driving parent to see them. It was not until 1962 that two designs with the purpose of protecting a child were developed independently. British inventor Jean Ames created a rear-facing child seat with a Y-shaped strap similar to today's models.〔(【引用サイトリンク】url=http://www.madehow.com/Volume-5/Child-Safety-Seat.html )〕 American Leonard Rivkin, of Denver Colorado, designed a forward-facing seat with a metal frame to protect the child.〔United States Patent and Trademark Office.
