Abstract
A shock absorbing system for impact energy dissipation employs removable unitary cells of compressible members in communication with a reservoir and containing a first working fluid. Resilient structural members may be placed intermediate the compressible members to deform responsive to compression to provide both energy dissipation and resilient recovery of the compression cylinders to their uncompressed state.
Claims17
A shock absorbing system for impact energy dissipation comprising:
- a surface;
- a least one unitary cell having a plurality of compressible cylinders extending substantially perpendicular to the surface each compressible cylinder containing a first working fluid;
- a reservoir connected to the plurality of compressible members through a plurality of fluid conduits, said first working fluid transferred by at least one compressible member to the reservoir responsive to compression of the at least one compressible member induced by an impact, wherein plurality of compressible cylinders and reservoir are enclosed within an envelope and wherein the envelope forms a cavity surrounding the compressible cylinders and reservoir;
- a second working fluid contained in said cavity and transmissible intermediate said the compressible members;
- a plurality of transverse tubes extending intermediate the unitary cells and,
- wherein each unitary cell is removably affixed to the surface.
3 more elements
A shock absorber comprising:
- at least one compressible cylinder containing a first working fluid and having an axis of compression, said compressible cylinder compressed from a first expanded position to a second depressed position responsive to an impact;
- at least one resilient accumulator expandable perpendicular to said axis of compression;
- and
- a conduit interconnecting the at least one compressible cylinder and the at least one accumulator, said first working fluid received by said resilient accumulator through said conduit upon compression of the compressible cylinder and returning from said resilient accumulator urging the compressible cylinder from the compressed position to the expanded position.
1 more element
A unitary cell shock absorber comprising:
- a plurality of pairs of compressible cylinders mounted in a unitary cell, each pair having a first cylinder uniquely connected to a second cylinder with a conduit, each first cylinder distal from the second cylinder in the unitary cell whereby an impact on one of the first or second cylinder will not create an impact on the other of the first or second cylinder.
