Open the CIPO recordAbstract From the Canadian patent
A method and an apparatus for absorbing the energy of shock impact loads are disclosed. In accordance with the method, an elastomeric member is axially advanced along a friction surface and into a confined condition upon impact loading to simultaneously provide friction and resilient deformation reaction forces having a substantially constant additive total. The elastomeric member is preloaded in an axial direction and the friction interface developed is of controlled lubricity to assure efficient energy absorption and uniform reaction forces independent of temperature and impact velocity. If velocity sensitivity is desired the, friction surface and preload can be modified to provide direct …
