ndeed, a rear-facing child restraint is also safe in the event of a rear impact.
On the one hand, we must bear in mind that seats with ECE R44/04 or R-129 approval have passed a rear-collision crash test. For R-129 this also includes a lateral crash-test. Both approval standards are currently in force. Therefore, every chair that is currently approved has exceeded this safety minimum.
We know that rear-facing seats are especially safe in front impacts. However, they are also safe in the event of other collisions. In this sense, we must take into account the differences between front and a rear crashes.
