A pivot fitting for moveable furniture parts on upholstered furniture has a first lever and a second lever that are mounted to as to pivot relative to each other about a common axis from a basic position through a predetermined angle. The pivot fitting also includes a clamping mechanism with which the two levers can be fixed relative to each other at different angular positions within the predetermined angle, the clamping mechanism has a toothing attached in a rotationally fixed manner on the second lever, at least one catch that is pivotally mounted on the first lever and loaded in the direction of the toothing, the catch engaging with the toothing in a detent position. A first control disc is mounted so as to pivot about the common axis, with which the at least one catch is disengageable from the toothing when the predetermined angle has been passed from the basic position into an adjusting direction, such that when the catch is disengaged from the toothing, the two levers can be pivoted back into the basic position when the predetermined angle is passed in a resetting direction. The first control disc can be carried by the toothing, resting thereon with a friction fit, and is mounted so as to pivot about a switching angle relative to the first lever and wherein a second control disc mounted so as to pivot about the common axis can be carried by the toothing and is mounted so as to pivot about a switching angle relative to the toothing.

Furniture seats, in particular relate to an electric sofa frame, comprising a bottom frame assembly, a sofa mounting frame, a leg assembly, a back assembly, a linkage mechanism and a first driving electric motor for driving the movement of the linkage mechanism. The movement of the linkage mechanism may cause the leg assembly and/or the back assembly to expand or contract; and further includes a fixing frame, a headrest assembly, a waistrest assembly, a second drive electric motor for driving rotation of the waistrest assembly, and a third driving electric motor that drives the headrest assembly to rotate; the headrest assembly and the waistrest assembly are connected to the back assembly via a mount. The utility model has the advantages of simple and compact structure, stable and reliable operation and can be used for providing the user with the head support and the waist support massage.

A computer cockpit including a cockpit body, a driving module, a sensing module and a controlling module. The cockpit body includes a seat, a backrest and a display interface all movably disposed on the cockpit body. The display interface and the backrest are respectively located at two opposite sides of the seat. The driving module and the sensing module are disposed to the cockpit body, and the sensing module is configured to provide sensing data. The sensing data includes a seat pressure sensing value and a backrest pressure sensing value. The controlling module is electrically connected to the driving module and the sensing module, and configured to send an adjusting command according to the sensing data. The driving module is configured to receive the adjusting command to synchronously rotate the seat, the backrest and the display interface to a working angle and reduce a difference between the backrest pressure sensing value and the seat pressure sensing value.

A system and computer implemented method for controlling an actuator in a reclining seat. A plurality of actuators are provided in a reclining seat, each actuator moving at least one portion of the reclining seat. Voltage spike pulses are generated as each actuator moves the at least one portion of the reclining seat. Voltage spike pulses of each actuator motor are counted as each actuator moves, and a configuration of the reclining seat is stored in a memory associated with the reclining seat.

Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided. Electrical systems for use in the powered chairs, and components for use in the electrical systems are provided. Control systems and methods for operating powered chairs are also provided. Any given chair may be locally and/or remotely controlled.

A headrest tilt mechanism is provided for installation on a chair. The mechanism includes a back insert that frames an area of the chair to be independently pivoted. A pair of spaced headrest tilts are coupled to the back insert, and pivotally coupled to the back frame of the chair. A lower connector tube is coupled to the back frame of the chair below the back insert. A linkage coupler is pivotally coupled to an upper member at an upper pivot point and is pivotally coupled an actuator at a lower pivot point. The upper member has a secured leg secured to the pair of spaced headrest tilts and a pivotal leg pivotally coupled to the linkage coupler. An actuator is pivotally coupled between the linkage coupler and the lower connector tube that can be actuated to pivot the headrest tilts from a closed to an open position.

A seat structure comprises a base configured to be a chair base assembly; a seat support located above the base, wherein a front part of the seat support has rotary connection with the front part of the base through a transition link; a chair back assembly having rotary connection with a rear part of the base through a pivot; a lever driving member linked between the chair back assembly and the seat support, and having rotary connection with a rear part of the seat support, wherein the lever driving member and the seat support are approximately on the same surface. When the chair back assembly rotates rearward around the pivot from the initial position, the rear part of the seat support is raised diagonally to the rear through the lever driving member, meanwhile the transition link and the front part of the seat support are pulled up.

This is directed to a smart ergonomic chair and mobility system. The system can be used as a working station, a working chair, a mobility device, a personal care device, or a combination thereof. The system is designed to provide ergonomic seating posture for a person who is seated on the chair. The system is also designed to reduce body stress by providing automatic movements of parts of the chair at predefined time points.
