Movement inducing module

A module for use with a chair having a seat portion supported by a support portion, for triggering movement of a person sitting thereon, the module being adapted to be attached to the chair between the seat portion and the support portion, the module comprising:

• a driving motor;
• a base platform adapted for fixed attachment to the seat portion;
• and
• an angled axis system (AAS) having a main rotary element having a main axis, and an auxiliary rotary element having an auxiliary axis coupled with the main rotary element so that the auxiliary axis and the main axis form an angle therebetween of 0.25-6 degrees, so that when the main rotary element rotates about its main axis, the auxiliary rotary element also rotates about the main axis main axis together with the main rotary element as a single body, the base platform being coupled to the auxiliary rotary element so that the rotation of the auxiliary axis moves the base platform entailing the seat portion to perform an oscillating combined rotary-tilting motion having an amplitude A defined by the angle, the motor is adapted to rotate either of the main rotary element and auxiliary rotary element to provide desired oscillation frequency f of 0.2-2 Hz so that the person seated on the seat portion is triggered to operate their joints and muscles to compensate for the movement in order to remain focused on a target, the frequency and the amplitude being such that the compensation of the movement by the person allows the person to remain focused on the target,
• wherein the AAS is formed of a top and bottom cylindrical portions which are integrally formed at an angle with one another, the bottom cylindrical portion constituting the main rotary element and its rotary axis constituting the main axis, and the top cylindrical portion constituting the auxiliary rotary element and its rotary axis constitutes the auxiliary axis, the main axis being substantially perpendicular to the seat portion, and
• wherein the base platform comprises a fixed unit and a moveable unit adapted for respective attachment to the support portion and the seat portion of the chair, and a retention member, adapted to prevent rotation of the fixed unit with respect to the moveable unit, while still allowing the oscillating combined rotary-tilting, and the module further comprises a top and a bottom bearing each having a respective inner ring and an outer ring, wherein the fixed unit, movable unit, top cylindrical portion and bottom cylindrical portion constitute a first group of four elements, and the inner rings and the outer rings of the respective top and bottom bearing constitute a second group of four elements, and wherein each element from the first group is adapted for coupling to exactly one element of the second group, and each element of the second group is adapted for coupling to exactly one element of the first group, so long as the fixed unit and the movable unit are not attached to the rings of the same bearing.

• the motor is adapted to rotate either of the main rotary element and auxiliary rotary element to provide desired oscillation frequency f of 0.2-2 Hz so that the person seated on the seat portion is triggered to operate their joints and muscles to compensate for the movement in order to remain focused on a target, the frequency and the amplitude being such that the compensation of the movement by the person allows the person to remain focused on the target.
