How does a side impact protection system work?
A side impact protection system (SIPS) is a safety system that protects the occupants of a car against injury in the event of another vehicle crashing into the side of it.
The side of the car body is reinforced, with energy-absorbing honeycomb materials being used inside the doors. The idea is to distribute the energy of the impact more widely across the whole side of the car, rather than having one area absorb it all.
