What is a Top Tether?
Top Tether are additional anchorage points located in different positions in the car (usually on top of the car seat or behind the rear seat) and used for the additional belt at the back of the child restraint system. In general, Top Tether systems are not required by law which is why not all car seats are equipped with this system. However, the additional belt at the top of the child restraint system reduces the forward displacement of the seat during a head-on collision offering additional safety in case of an accident. Therefore, Top Tether systems are frequently used, especially in newer car seat models from various car seat manufactures.
