Seat with Adjustable Dynamic Joint
WiSys: T07027US

Inventors: Hans Jensen, Robert Jensen

In today’s increasingly sedentary and technology-dependant culture, people spend long hours sitting every day. Prolonged sitting has an extensive and well-documented list of negative health effects upon the human body. Next to the common cold, lower back pain is the biggest reason for worker absenteeism. Although sitting requires less physical effort than standing or walking, it puts a great deal of stress upon the lower body. Simply put, the human body is not physiologically suited for extended inactivity.
The Invention
The Adjustable Dynamic Joint is a dynamic solution to a static problem. The ability of the ADJ to continuously redistribute stress across muscles and ligaments provides a revolutionary way to significantly reduce the effects of prolonged sitting upon the human frame. The joint, which provides motion in 360 degrees, allows the user to exercise core muscles with natural daily movements. The ADJ can be fitted into seating in a wide range of environments, such as the home, office or car.
Key Benefits
  • Enables the body to make small, constant movements to eliminate static strain and provide light exercise.
  • Makes movement intuitive and natural.
  • Readily integrates with other industry standard chair components, such as the height adjuster mechanism, gas lift, star base, etc.
  • Promotes core stability and strengthens core muscles, including back and abdominals.
  • Provides a controlled seating alternative to the inflatable balance ball.
  • Improves balance and posture.
  • Allows for hands-free posture flexibility and controlled freedom of movement.
  • Is user-friendly and easily adjusted to achieve desired range of motion.
  • Is less expensive to produce than current market options
  • Uses a unique system of inexpensive elastomeric discs that can be customized for specific applications.
