Chin Guard Assembly for Restricting Downward Head Tilt

Instead of blocking vision with glasses (conventional approach), this invention uses a chin guard that physically prevents the head from tilting downward. The approach is inverted from occluding the visual field to mechanically constraining the head position, thereby preventing looking down without creating visual distortion or forcing players to adapt by developing new negative tendencies.

The chin guard acts as an intermediary mechanical device between the player's intent to look down and the actual head movement. By placing a physical barrier (chin guard with shaft and chin support) that contacts the chin and neck, it mediates and restricts the downward tilting motion without requiring visual obstruction, thus preventing the harmful behavior directly rather than through visual manipulation.

The chin guard incorporates dynamic elements including a telescoping shaft with adjustable length and a flexible neck securing assembly that can accommodate natural head movements. The device transitions from a completely rigid structure to a dynamically adjustable one, allowing lateral rotation and natural head motion while maintaining restriction on excessive downward tilting through the angular geometric constraint.

The geometric constraint uses asymmetric angular configuration (shaft at an angle to the chin support) that selectively restricts movement in one direction (downward tilting) while permitting movement in other directions (lateral rotation). The asymmetric angle creates a mechanical advantage that blocks downward motion but allows sideways movement, thus achieving directional selectivity in movement control.
