摘要： The object of the invention is a convertible, dual function chair for sitting and kneeling, which gives the possibility of changing the position and relieving the spinal column during a prolonged work in a sitting position.
The dual function chair for sitting and kneeling is equipped with a movable backrest and headrest support, shaped in the lower part in such a way that its displacement changes the size of the chair simultaneously vertically and horizontally. It is also equipped with a sliding-rotating-returning or a sliding-returning backrest device, which makes it follow the user's back and support it accurately at every angle of inclination of the backrest when tilting the backrest. It is also equipped with a headrest connected to the headrest arm through a rotary-sliding mechanism, which rotationally connects with the backrest support, and has a specially shaped five-star base, in which the arms, apart from the fragment above the wheels, are maximally flattened and located as low as possible above the ground.-

摘要： The adjustable headrest mechanism for a chair comprises a pair of sliding rails; an upper driving rod and a lower driving rod, the upper driving rod being attached to the sliding rails and the lower driving rod being attached to a back frame of the chair; and a headrest actuator pivotally connected between the upper driving rod and the lower driving rod for operably driving the upper driving rod to move between a first position and a second position, thereby driving the sliding rails to pivotally move in an upward direction or a downward direction relative to the lower driving rod. When the upper driving rod is in the first position, the sliding rails is in a complete close state. When the upper driving rod is in the second position, the sliding rails is in a complete open state.

摘要： A reversible adjustable lumbar support and headrest tilt mechanism is provided for installation on a chair. A side bracket is coupled to each side of the back frame, and a back bracket is pivotably coupled to each side bracket. An actuator is pivotably coupled to the back frame that has an extendable and retractable shaft. In a first orientation, with the actuator shaft extending toward the upper end of the back frame, a headrest back insert is couple-able to and between the back brackets, such that extension and retraction of the actuator shaft rotates the headrest back insert. In a second orientation, with the actuator shaft extending toward the lower end of the back frame, a lumbar push bar is couple-able to and between the back brackets, such that extension and retraction of the actuator shaft rotates the lumbar push bar.

摘要： An ergonomic workstation that includes a base; an effective hip axis affixed to the base; a seat bottom that rotates about the effective hip axis; a seat back that rotates about the effective hip axis; an effective shoulder axis positionally fixed to the seat back; an effective elbow axis positionally fixed to the seat back; a monitor support having a monitor mount that rotates about the shoulder axis; and an input device tray support configured such that an input device tray on the support rotates about the elbow axis. As the workstation moves through a broad range of operational zones, it maintains a fixed eye-to-monitor distance and fixed angle between the user's head and the monitor throughout a significant portion of the range of motion, and a fixed distance from the user's elbow to an input device throughout the entire range of motion.

摘要： The invention provides an article of adjustable furniture (10), preferably an adjustable chair or bed, comprising a floor standing base section (16), adjustable seat (18), backrest (20) and headrest (130) sections and actuator means (100) for moving the backrest and headrest sections. The seat section is movably mounted with respect to the base section. The backrest is movably mounted with respect to the seat section and the headrest is movably mounted with respect to the backrest section. The actuator means includes a single actuator (102) for co-ordinated movement of the adjustable backrest and headrest sections for selectively altering the configuration of the article of furniture. The actuator has a first range of movement for moving the headrest with respect to the backrest, and a second range of movement for moving the backrest with respect to the seat section to provide a recliner function. The invention also provides an article of adjustable furniture comprising a backrest (20) and an adjustable headrest (130) pivotally mounted with respect to the backrest, actuator means (100) for moving the headrest between raised and lowered positions, and guide means arranged between the headrest and the backrest for rotating the headrest with respect to the backrest as it moves between said raised and lowered positions. The guide means includes first (138) and second (140) guides, each associated with one of the backrest and the headrest and having at least one follower (142, 144) associated with the other of the backrest and headrest. The first and second guides are inclined with respect to each other such that a turning moment is generated on the headrest when the headrest is raised or lowered.

摘要： A seat back recliner is revealed. A seat back is pivotally connected to and positioned on a rear end of a seat part of a chair while a cylinder is disposed between the seat part and the seat back. A reclined angle of the seat back is adjustable under control of the cylinder. Thereby a user sitting on the chair can directly adjust the seat back to the reclined angle required. The reclined seat back allows a user to lie back and have the greatest level of comfort and relaxation while sitting on the chair.

摘要： An item of seating furniture, including a base, a seating unit, a backrest unit having a back contact surface, and a headrest unit with a head contact surface. The headrest unit is movable between a storage position and an operating position. The headrest unit is arranged in the storage position in such that the head contact surface is fully behind the back contact surface and below the top edge thereof. The headrest unit is pivotable about a headrest rotation axis along a nonlinear movement path, or is movable along a linear movement path opposite the base. The backrest unit is movable along a second movement path deviating from the movement path of the headrest unit, wherein the movement of the backrest unit is coupled to the movement of the headrest unit via a movement mechanism of the headrest unit.

摘要： The present disclosure describes a seat. The seat may include a stationary support frame at least partially defining a cavity. The seat may also include a backrest cushion, a headrest, and a motion mechanism. The motion mechanism has a headrest assembly allowing movement of the headrest between a retracted position and an extended position. When the headrest is in the retracted position, the headrest is hidden from view within the cavity of the support frame. When the headrest is in the extended position, the headrest is visible above the backrest cushion.
