This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,084.

Summary of the Inventive Concept

The present invention relates to an intelligent ergonomic chair that incorporates advanced technologies to provide optimal user comfort and support. The chair features dynamically adjustable hinging axes, self-leveling mechanisms, and dynamic lumbar support systems, ensuring a tailored fit for each user.

Background and Problem Solved

The original chair with pivoting seat and backrest, as described in Italian Patent Application No. 102021000006467, has limitations in providing optimal ergonomics for users of varying weights and preferences. The present invention addresses these limitations by integrating sensors, controllers, and advanced mechanisms to create a highly customizable and adaptive seating solution.

Detailed Description of the Inventive Concept

The intelligent ergonomic chair comprises a frame with dynamically adjustable first and second hinging axes, which are adjusted based on user weight and ergonomic preferences detected by integrated sensors. The chair also features a self-leveling mechanism to maintain the seat and backrest in a horizontal plane, ensuring optimal support and comfort. Additionally, the dynamic lumbar support system adjusts to the user's back curvature, providing tailored support and reducing fatigue. The chair's advanced systems are controlled by a central controller, which receives input from the sensors and adjusts the chair's settings accordingly.

Novelty and Inventive Step

The present invention's novelty lies in the integration of advanced technologies, such as sensors and controllers, to create a highly customizable and adaptive seating solution. The inventive step is in the dynamic adjustment of the hinging axes, self-leveling mechanism, and dynamic lumbar support system, which provides a tailored fit for each user and addresses the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the intelligent ergonomic chair could include variations in the type of sensors used, the design of the self-leveling mechanism, or the implementation of the dynamic lumbar support system. Additionally, the chair could be integrated with other technologies, such as AI-powered ergonomic analysis or wearable devices, to further enhance its functionality and user experience.

Potential Commercial Applications and Market

The intelligent ergonomic chair has significant commercial potential in various industries, including office furniture, healthcare, and gaming. The chair's advanced features and customizable design make it an attractive solution for companies seeking to improve employee comfort and productivity, as well as for individuals seeking a premium seating experience.
