Abstract

A chair is stabilized in two orthogonal axis, pitch and roll, can hold a person stable in relation to the horizon. This solution to motion sickness is effective because the fluid in the inner ear no longer moves in relationship to the vehicle motion upon which the person is located. Therefore a main cause of motion sickness is substantially reduced or eliminated. Additionally, the invention can be a table, a bed, or even an entire room that is isolated from the rolling, pitching and jolting imparted by the host vehicle. Additionally, some applications such as a chair and table, may be stabilized in a third orthogonal axis, azimuth.
