Low viscosity liquid (12) is trapped in between members (10 and 11) and on impact of member (10) with an obstacle a frangible membrane (13) can burst causing a high velocity liquid jet to be expelled through channel (11a) thus dissipating the impact energy.

Why it's free to use
- Filed November 4, 1996 and granted April 22, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 4, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 4, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
