Latest Patents
Fred C. Liebertz holds a patent for a tilt mechanism specifically designed for knee-tilt chairs. This mechanism features a unique design where the seat and pedestal of the chair are connected by a knee-tilt mechanism. The first support is fixed to the underside of the seat, while the second support is attached to the pedestal, incorporating a sidewardly extending support tube arrangement. The design allows for a horizontal tilt axis, with a restoring mechanism that exerts a torque to return the seat to its horizontal position.
