Provided are a chair frame and a chair. The chair frame supports a human waist and back by using a waist support assembly and supports human legs and feet by using a footstool assembly. Meanwhile, when the waist support assembly is unfolded, driven by a second support rod, a second end of a first support rod can swing toward the footstool assembly with a junction between a first end of the first support rod and the second support rod as a rotation center to increase an included angle between a waist support bracket and a seat cushion bracket, that is, increasing an unfolded angle of a backrest and achieving the zero gravity effect. The chair can improve the chair comfort by applying the preceding chair frame.

Provided are an elderly chair support and an elderly chair. A support assembly of the elderly chair support includes a support plate () and an anti-torsion tube () fixedly connected to the support plate (); two ends of a first lifting rod () are pivoted to the support plate () and a base () respectively, and two ends of a second lifting rod () are pivoted to the support plate () and the base () respectively; and a first drive assembly is capable of driving a power rod () to rotate relative to the support plate () to have a first position and a second position, in the case where the power rod () is at the first position, a leg assembly () stretches and the anti-torsion tube () abuts against the base (), in the case where the power rod () is at the second position, the leg assembly () retracts and the anti-torsion tube () has a first distance from the base (), and in the case where the power rod () is at the second position, the first drive assembly is capable of driving the power rod () to drive the support plate () to move synchronously so that the support plate () has a second distance from the base (). The elderly chair support and the elderly chair have high stability and are simple in structure.

Provided are an adjustable bracket and a high-feet sofa. In the adjustable bracket, the transmission rod is in a straight rod structure. A first end of the transmission rod is connected to the fourth connection rod. A second end of the transmission rod is connected to the pedal rod group. The present disclosure provides an adjustable bracket. In the case of the same sitting height, the adjustable mechanism of a sofa has a more compact structure so that the cleaning work of a mop, a vacuum cleaner, or a floor-sweeping robot is facilitated. Moreover, the height of the sofa from the ground is higher, making the sofa more attractive.

Adjustable bracket and high-feet sofa

A seat frame includes a base, a driving member and a stretching member. The driving member and the stretching member are disposed on the base. The stretching member includes backrest assemblies, cushion support assemblies and leg rest plate assemblies which are positioned on left and right sides of the base and set in pairs. A front end and a rear end of the cushion support assembly are hinged with one end of the backrest assembly and one end of the leg rest plate assembly respectively. When the seat frame is in a television (TV) posture and a lying posture, and the leg rest plate frame is inclined upward with respect to a horizontal plane.

Seat frame

In a sofa seat stretching device, one end of a second support facing away from a first support, and a second leg rest plate connector are hinged at a fourth hinge point, so that the stretching assembly's stretching speed is reduced in a process of switching from a sitting position state to a lying position state when a driving assembly acts in the same way, and the weightlessness feeling can be effectively avoided. Moreover, the driving assembly drives the stretching assembly so that the process of switching the stretching assembly from the lying position state to the sitting position state is smoother.

Sofa seat stretching device

Provided are an ottoman linkage device, a frame body, and a seat. The ottoman linkage device includes an upper link, a lower link, a middle ottoman link, a first front ottoman link, a second front ottoman link, a first connection link, a second connection link, a front ottoman bracket, and a middle ottoman bracket. The upper link or the lower link is rotatable under a driving force to make the ottoman linkage device unfold or fold. By changing the length of the first connection link and the length of the second connection link, the magnitude of the driving force of the first connection link can be adjusted.

Ottoman linkage device, frame body, and seat

The present application provides an intelligent sofa mechanical extension device, including a base, a driving component and an extension component, where the driving component and the extension component are disposed on the base. The driving component includes a motor and a motor guide rail that are disposed on the base. The motor guide rail is provided with a motor moving slider in a slidable manner. An end of the motor is connected to the moving slider. The moving slider is connected to a driving rod through a drive connector. The driving rod is disposed on the seat cushion support assemblies on the left and the right side. The extension component is driven to stretch or retract with back-and-forth movement of the motor moving slider along the motor guide rail.

Intelligent sofa mechanical extension device

A mechanical extending linkage is configured to be mounted in a seating unit capable of being moved between a retracted position and an extended position and comprising a seat, a backrest and extendable primary and secondary footrests. The mechanical extending linkage comprises a footrest assembly for extending and retracting the primary footrest and the secondary footrest, the footrest assembly comprising a primary footrest link, a secondary footrest link, and an intermediate link set having a first intermediate link, a second intermediate link, a third intermediate link and a fourth intermediate link. The footrest assembly is configured in such a manner that the secondary footrest link, the first intermediate link and the second intermediate link are arranged substantially parallel with the seat when the seating unit is in the retracted position.

Mechanical extending linkage and seating unit comprising the same

A sofa () having adjustable backrest position, and including a seat frame (), a backrest frame (), a guide-rail frame () and a driving device (); the guide-rail frame () includes a guide-rail () which is fixedly connected to the seat frame () and which extends in the front-back direction of the sofa (); a first end of a support frame () is connected to the backrest frame (); a second end of the support frame () is connected to the guide-rail () so as to be able so slide relative thereto; the driving device () is arranged so as to be linked-motion connected to the support frame () in order to lead the second end of the support frame () to slide relative to the guide-rail ().
