System prevents kids from potentially slipping down the ski lifts. A permanent magnet is attached to the seat of the ski lift. A back protector with a metal plate is worn by the child. The back protector only weighs 200g. The magnets on the seat is activated when the child gets on the seat. It deactivates when it reaches the top. Even if safety bar is lifted too early, magnet system prevents child from slipping of seat.
