First Claim
Patent Images
1. An ergonomic antifatigue device for moving the hips and lower midsection of a person seated in a seating apparatus, the device comprising:
- a first support having a support element positioned under the hips of the seated person, said support element comprising a left side and a right side;
a central point located substantially within said support element;
a second support structure connected to said support element at said central point for maintaining said central point in a substantially non-moving position while allowing movement of all portions of said support element other than said central point; and
a motor and coupling connected to said first support;
said motor and coupling automatically and alternately pivoting said left side of said support element up and down about said central point, and automatically and alternately pivoting said right side of said support element up and down about said central point, thereby automatically and alternately lifting one hip of the seated person and then the other hip;
said motor and coupling also automatically and alternately rotating said support element back and forth about said central point as a series of cyclical rotations and counter-rotations, thereby cyclically moving backward and forward the hips of the seated person;
whereby motion and stimulation are translated to the seated person in a similar fashion to the motion and stimulation imparted to a person through walking.
