  • Up until the joint Australian Standard for Child Restraints was revised in 2013, child restraints could only use an in-built harness for children up until approx. 4 years of age. After that the child had to use a booster seat using the car's lap sash seat belt. Unfortunately there is a chance that children are not wearing their seatbelts correctly with booster seats which can be fatal in a crash. The use of a 6-point harness, as used on the Maxi Guard PRO, is an ideal harnessing system and is used on all child restraints in Australia for children up to 4 years of age. This harnessing system has been extended to suit older & larger children in the Maxi Guard PRO and has been extensively tested for strength.

  • As cars are designed for average adult sizes, children in child safety restraint are often not positioned in these active safety zones (e.g. curtain airbag zone) in the vehicle. Maxi Guard PRO has a revolutionary dual side impact protection system (SICT™) to provide superior protection in case of a side crash. In the headrest there is a cushion that surrounds the head on 3 sides which protects the head against crash impact forces. The larger air cushion on the outside of the seat moulding is designed to reduce the crash forces on the child's torso, the chest and the child's heart. The SICT™ system is patented by Britax.

  • One of the problems in restraining a larger occupant in a child restraint is that the loads within the seat belt and the tether strap are increased. The seat belt has extra capacity but the tether strap anchorage fitting or anchorage point in the car may not have sufficient strength. As such, AS/NZS 1754:2013 has nominated a maximum load of 7 kN that can be applied to the anchor fitting in the required simulated crash testing. This required significant design challenges to keep the tether strap loads below the 7 kN maximum. The Maxi Guard PRO uses a structure in the top of the seat moulding where the tether strap is attached that flex sufficiently to ensure that the load remains below the 7 kN.

  • One of the problems when a child gets into their seat or they are placed in to the seat they sit on the buckle making it annoying to pull out from under the child. The seat is fitted with a patented flip forward buckle pad (called EZ-Buckle system) which flips the buckle forward when the buckle tongues are released. Next time that the child gets in to the seat the buckle is still fitted forward and can be easily found to then engage the harness straps.

    The internal dimensions of the seat will fit 95th percentile of 8 year olds thus the Maxi Guard PRO will continue to fit some children within the seat shoulder height marking system until 10 or 11 years of age.
