I'm afraid not David, it isn't designed to do so. Here's a link to some findings about head protection that
was introduced to protect against concussion:

"Although some boxers wear head protection, in a bid to prevent injury, they might not guard against brain damage."

"Boxing head-guards do not prevent Cerebral Trauma"
"Boxing bouts are often stopped because of facial cuts, which have little impact on neuro-cognitive performance, but look horrific because of the sight of blood."
As you see, they fail to do so, because protecting the outer layers of the head against cuts (which cycle helmets can do, in the right circumstances, in the same way as padded knee supports can protect your knees) does not stop the sudden deceleration of the brain in the skull (which is what causes concussion).
If you or your kids ever fall so as to crush your helmet, please get checked for concussion, because helmets do prevent the immediate signs that indicate the possibility of this, such as bleeding scalp wounds.
Oh dear...
So over all playgrounds (which are relatively safe compared to other risks that children are exposed to), including those spongy-surfaced ones 11% of accidents!

"
Professor Ball's report confirms that the risk of injury in UK playgrounds is low in comparison to the other risks to which children are exposed and have changed little in the period covered by the research. The report identifies the major risk factors in playgrounds as behaviour, equipment height, and body orientation in falls to the ground. Professor Ball notes that despite the introduction of playground safety measures such as IAS (impact absorbing surfacing), playground injuries are not decreasing. IAS is a surfacing material designed to reduce the risk of head injuries by absorbing the impact of a fall. Professor Ball found that the scientific evidence of the effectiveness of IAS as a risk reduction measure is mixed and he raises doubts as to whether the costs of IAS are proportional to the resulting reduction in injuries to children."
You are misinformed again here David I'm afraid!
