Technical Field

[0001] The utility model relates to the technical field of office furniture, in particular to an office chair with the function of correcting sitting posture. Background Art

[0002] Office chairs are widely used in various office spaces. At present, more and more attention is paid to comfort, functionality and height adjustability.

[0003] Sitting in an office chair for a long time will cause muscle soreness due to incorrect sitting posture. Existing office chairs with corrective sitting posture usually limit the user's sitting position and correct the sitting posture by limiting the position of the backrest. The position of the user's hunchback is not fixed, so there is a need for a corrective sitting posture office chair that is suitable for different users. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an office chair with a sitting posture correction function, which solves the problems raised in the background technology.

[0006] Preferably, the chair back is composed of three sections of articulated rods, wherein the articulated rod connected to the chair frame is a telescopic articulated rod.

[0007] Preferably, a limiting sleeve is fixedly installed on the upper and lower sides of the rear end of the backrest, an extension rod is slidably connected inside the limiting sleeve, and a side support is fixedly installed on one end of the extension rod.

[0008] Preferably, the shape of the iron core is a "diamond" and the thickness of the iron core is smaller than the diameter of the sliding rod.

[0009] Preferably, a limit nut is provided at the hinged end of the hinged rod, and the limit nut is a quick locking nut.

[0010] Preferably, a motor for generating vibration is embedded inside the seat cushion, and the motor is controllably connected to the induction coil.

[0011] The utility model has the following beneficial effects:

[0012] 1. The office chair with the function of correcting sitting posture adjusts the height of the chair back so that the fixing plate is located below the bending point of the user's spine and makes the fixing plate perpendicular to the seat cushion. The user sits on the seat cushion in a standard sitting posture. When the user bends over and no longer maintains the standard sitting posture, the sliding rod is squeezed to drive the iron core to move backward. The iron core slides in the induction coil to generate an induced current, which controls the vibrating seat cushion to remind the user to maintain a good sitting posture.

[0013] 2. The office chair with the function of correcting sitting posture has a chair back composed of three sections of hinged rods, among which the hinged rod connected to the chair frame is a telescopic hinged rod. Through such a setting, the height of the fixed plate can be adjusted to adapt to spines with different degrees of curvature. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The present invention provides an office chair with a posture correction function:

[0021] Embodiment 1, as Figure 1-4 As shown, it includes a chair frame 1, a vibrating seat cushion 2 is arranged above the chair frame 1, a motor for generating vibration is embedded inside the seat cushion 2, and the motor is control-connected to the induction coil 402.

[0022] The rear end of the chair frame 1 is provided with a chair back 3 with adjustable height, which is composed of three sections of hinged rods, wherein the hinged rod connected to the chair frame 1 is a telescopic hinged rod. The hinged end of the hinged rod is provided with a limit nut, which is a quick locking nut.

[0023] A fixing plate 4 which is perpendicular to the seat cushion 2 is arranged at one end of the chair back 3 away from the chair frame 1, a backrest 5 which generates an extrusion signal is arranged at the front end of the fixing plate 4, a limiting sleeve 501 is fixedly installed on the upper and lower sides of the rear end of the backrest 5, an extension rod 502 is slidably connected inside the limiting sleeve 501, and a side support 503 is fixedly installed at one end of the extension rod 502.
