Schuberth's A.R.O.S. System Brief Explanation
So why is the AROS an important addition to the motorcycle helmet? As its very name says, the AROS will not allow the properly locked in helmet to roll off the wearer's head. While the chin strap secures the helmet in place and will oppose any lift action, the same does not apply to other helmets.
The ECE testing standards requite that a properly locked helmet does not pivot forward more than 30 degrees. This limitation has to do with both helmets coming off the head and injuries sustained as the chin of the lid hits the rider/ passenger's throat or chest. Limiting the pivoting action significantly reduces this type of injuries.
Schuberth's AROS helmets come with dual extra straps linking the rear portion of the shell to the chin straps, reducing the freedom of movement in case the helmet is pulled towards the front. ECE tests have to be make with a 10kg (22 lbs) weight attached to the back of the helmet and dropped from a height of 75cm (29”), just as you can see in the pictures after the jump.
Luckily for the owners of Schuberth helmets, the forward pivoting is restricted to 15 degrees, so in this respect, the AROS helmets are way more secure.
