The “gap” near the red release buckle allows a child to get sufficient leverage to remove the straps off the shoulders. Otherwise, the five point car seat harness offers the best protection to your child as it is a bespoke fit every time you buckle up. The same cannot be said for other child restraint systems (CRS)
Car seats fitted with a five point harness offer unparallelled levels of safety. The five point harness is used by racing drivers and pilots who understand the reasons for wearing the harness!
No matter how well behaved children are, they are NOT dummies!
Children on the other hand, do not understand the importance of car seat safety.
They are not content to be fastened back if there is an easy option to wriggle and be unrestrained.
Standard five point harnesses have a design flaw when used in the environment of children, there is a gap immediately above the red release button that enables a child to slide their hands easily through and remove their shoulders. In a manufacturing environment such hazards would have a shield or guard to help prevent misuse. Watch what happens in the event of a frontal impact when a child escapes from their car seat harness.
The “5 point plus”, simply shields the gaps through which children escape from the harness. So even when children pull in their stomach to create more room between harness and body to enable slipping the harness of their shoulders, it is still not possible to escape!
Crash testing was central to the design of the 5 point plus and was subjected to crash tests as specified by ECE R44 regulations.
The “5 point plus” can be fitted retrospectively by parents, in around 20 seconds. See it in action.
