What is the SIP+ for?

The additional side impact protection SIP+ can be placed onto the side of the iZi Flex FIX i-Size facing the vehicle door to further enhance the side impact protection, yet the iZi Flex FIX i-Size has already passed the demanding crash test criteria of the UN R129-02 regulation without the SIP+. Its main function is to reduce the distance between the seat and the vehicle door, thereby enabling an earlier contact in a side impact that leads to less movement.
