How have we adapted to the new BSI proposed changes?
« on: August 30, 2013, 08:46:34 AM »

The answer to this question is we haven’t.

With our research carried out with Loughborough we are confident that the entire AdiPower range will conform and excel when the new BSI standard is introduced later in 2013.

With our research that was carried out back in 2007/8 we foresaw the issues at hand after speaking to Dr Andy Harland at The Sports Technology Institute at Loughborough University, as a result of this visit we were made aware of where injuries were occurring within the game surrounding helmet safety. The majority of these were around the frontal area where the grille and peak were highlighted as an area of weakness as they were still letting the ball through to strike the wearers head, or forcing the grille upon to the face causing laceration injuries.

With this in mind we set about designing a shell shape that optimised peak strength and significantly reduced sideways deformation upon frontal impact. The most effective way we could see of achieving this was to design a shell that had a rib running down the central section of it that would avoid having a 90 degree (or close to) at the peak section which mean flexion occurred more readily. By inserting this rib and creating a ramp shape it meant we could have a flat under-peak to increase the field of vision when wearing the helmet as well.

The flared arches on either side of the helmet are present to help reduce any sideways deformation, a lot like the arches on a car that add structural strength to these areas.

We realise the shape of our helmets may divide opinion as some people don’t realise or appreciate why the shape is designed as it is and snap judgements are made due to this. However when we set out to innovate and evolve the cricket helmet design we embraced the fact that we have a clean slate and could address the issues that older more traditional designs faced with regards to the safety provided by them.

We hope that now the ICC and BSI are being proactive in moving the safety standards forward we can continue to provide the safest possible helmet to the players wearing them be it at International or amateur level of the game.

We will continue to innovate and work at this as the materials available for use in the products moves at a rapid pace and we are more than happy to embrace these developments.

Following on from our Blog post about the shell shape and design, heres a couple of short video putting the theory into practice about the deflective qualities.

Excellent read, cheers for the info.

Are the videos 60mph at impact? If so what would the equivalent bowling speed be?

Tom,

From my (limited and recent) exposure to helmets and the like as well as reading the history I think you have done a great deal to drive forward helmet safety.

You have to think that without ayrtek presence on the scene, other companies would have just maintainedttheir status quo. I'd hazard a guess that the icc/bsi changes are at least partly driven by ayrtek showing what can be done!

The speed is 60mph when fired from the cannon which is 0.6m from the headform. This is where the impact speed of 67mph has been calculated for the ball penetration test taking into acount that when a bouncer hits the pitch is will decelerate by approx 12-15mph to the point of impact. i.e. 80mph bounder- 12mph when hitting pitch and travelling distance to batsmen = 67mph at point of impact.

More on this shortly when looking at the ball penetration testing.....
