A child safety harness is NOT an inbuilt harness: it is an additional product to purchase.

A child safety harness is attached to a child restraint anchorage point and is sometimes used with a booster seat or lap-only seatbelt.

A child safety harness is difficult to fit correctly. Do not use a child safety harness where a lap-sash seatbelt is available. Research recommends using a child safety harness only in situations where it is not possible to replace your lap-only seatbelt with a lap-sash seatbelt.

If you are not able to replace your lap-only seatbelt with a lap-sash seatbelt you will need to use a child safety harness with a booster seat. In this case, it is recommended to use a booster seat with an anti-submarining feature to hold the lap part of the seatbelt down low on the child’s hips. Examples of anti-submarining features are displayed below.


An anti-submarining feature

If you must use a child safety harness, ensure that the shoulder straps are not too tight and that the lap part of the seatbelt is very low across the thighs, otherwise it may ride up into the child’s stomach area. This may cause serious injury or death to a child in a crash.

The harness must be checked for correct fit every time it is used.
