Shock absorbing devices using rheopexic fluid
First Claim
1. A shock absorbing device using rheopexic fluid comprising:
- means defining at least one deformable sealed chamber which is subjected to externally applied shock forces; and
rheopexic fluid having an original viscosity and being filled in said at least one deformable sealed chamber such that when said at least one deformable sealed chamber is subjected to the externally applied shock forces, shear stress is exerted on said rheopexic material in said at least one deformable sealed chamber due to deformation of said at least one deformable sealed chamber to cause said rheopexic fluid to increase its viscosity from its original viscosity and to thereby increase its shock absorbing characteristics with increasing shear stress applied thereto, said rheopexic fluid reverting back to its original lower viscosity after abatement of said shock forces and resultant shear stress.

Abstract
Shock absorbing devices utilize rheopexic fluid contained in a deformable sealed chamber which is subjected to external shock forces. Upon application of the shock forces to the deformable sealed chamber, the rheopexic fluid filled therein is exerted with shear stress which causes the rheopexic fluid to increase its consistency and shock absorbent characteristics as a function of increasing shear stresses applied thereto. Additionally, when used in an application wherein the device is placed against a body part of a user, the rheopexic material "molds" itself to the body portion of the user. When left at rest, the rheopexic material returns to its initial fluid, low-consistency state.
