Many's a true word spoken in jest BFG.
Given that across the Big Pond they wear helmets that'd protect a scooter rider from head injury, yet the sport of Americian Football has far more serious problems with concussion and serious head/neck injuries than Rugby Union has. The introduction of such safety gear into the game of Rugby would create more problems than it would solve.
:knuppel2: The rise in serious injury in our sport is due to a rise in cynical foul play
in the Professional game
Players must be made responsible for the safety of their opponent. Rather than any additional safety gear, why not make players liable to civil/criminal prosecution for acts of foul play outside the laws of the game? If you punch somebody and go to court for it, I suggest that player won't do that repeatedly. Once or twice maybe, but a career change (or prison sentence) would come along time before for example - Dylan Hartley's run of 7 suspensions. Doesn't Health and Safety at work apply to Professional rugby player? If not, why not? If one is guilty of deliberately inflicting injury to a colleague at his place of work - that is surely gross misconduct and valid reason for getting one's walking papers.
Rugby Unions are at a loss as to how to deal with the issue for years now, the law of the land(or health and Safety people) would put and end to such acts fairly swiftly. If you think that's far fetched, consider Racing Metro are taking South African to court for quitting his job.

The notion that it is a Sport and so opposition players accept the risks, doesn't wash when it comes to deliberate/cynical acts of foul play. Yes accidents can happen, but enough is enough with deliberately ending an opponents career (tetraplegia for example) with dangerous foul play.
