Shock absorbers for protective body gear

摘要

Shock absorbers for integration into protective structures generally take the form of hollow, fluid-filled, compressible cells. In various embodiments, the cell enclosure includes one or more orifices, or vents, through which a fluid (such as air or water) can escape from the inner chamber formed by the enclosure.

主权项

1. A compressible cell for attenuating impact forces imparted thereto, the cell comprising:
an enclosure defining an inner chamber for containing a fluid, the enclosure comprising a non-corrugated bottom wall, a top wall including at least one corrugation defining a periphery around a central portion of the top wall and being spaced from the bottom wall, and a side wall extending between the top and bottom walls, the side wall and the at least one corrugation of the top wall resistively yielding in response to an impact imparted to the top wall so as to attenuate impact forces while allowing the cell to compress, the enclosure further comprises at least one orifice for resistively venting fluid from the inner chamber so as to at least partially attenuate the impact.
