<P> 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"). </P> <P> In 1990, the ISO standard ISOFIX 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 . </P> <P> In 2013, a new car seat regulation was 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 . </P> <P> 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 . American Leonard Rivkin, of Denver Colorado, designed a forward - facing seat with a metal frame to protect the child . It is noted that seat belts for adults were not standard equipment in automobiles until the 1960s . </P>
