Description

Technical Field

[0001] This application relates to the field of seating, and more specifically, to an ergonomically designed seating. Background Technology

[0002] Ergonomic chairs are a new type of environmentally friendly and healthy chair widely used in modern homes, entertainment venues, internet cafes, hotels, leisure facilities, conference rooms, and office computer desks. The backrest of an ergonomic chair can often rotate around the seat to accommodate the user's need to lie down and rest. However, because the neck support is not adjustable, these chairs cannot effectively support the necks of people of different body types. Furthermore, since many parts of these chairs are fixed, they lack dynamic support and cannot adjust to the user's movements.

[0003] Now an ergonomic chair has been developed. Utility Model Content

[0052] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] Reference Figures 1-6 An ergonomic chair includes: a seat body, a mounting shaft 21, an arc-shaped rod 22, a mounting column 23, and a neck cushion 25;

[0054] The seat body includes: seat cushion 11, backrest 12, armrest 17, base 13, casters 14, reinforcing ribs 18, first reinforcing support plate 19, and second reinforcing support plate 20;

[0055] Two armrests 17 are symmetrically positioned and fixedly connected to both sides of the seat cushion 11. A pulley 14 is mounted on the base 13, a gas spring 15 is fixedly connected to the base 13, and an adjustment handle 16 is mounted on the gas spring 15. The upper end of the telescopic rod inside the gas spring 15 is fixedly connected to the bottom wall of the seat cushion 11. One end of a reinforcing rib 18 is bent and fixedly connected to the bottom wall of the seat cushion 11. The reinforcing rib 18 is made of elastic plastic and is elastic. A first reinforcing support plate 19 is rotatably connected to the reinforcing rib 18, and its end wall is fixedly connected to the side wall of the backrest 12. A second reinforcing support plate 20 is rotatably connected to the upper end of the reinforcing rib 18, and its end wall is fixedly connected to the side wall of the backrest 12.

[0056] The mounting shaft 21 is fixedly connected to the reinforcing rib 18, the arc-shaped rod 22 is rotatably connected to the mounting shaft 21, and the mounting column 23 is fixedly connected to one end of the arc-shaped rod 22. A limiting groove 26 is provided in the side wall of one end of the mounting column 23.

[0057] In order to adjust the tilt angle of the neck cushion 25, two sets of adaptive components are provided. The adaptive components are symmetrically located at both ends of the mounting column 23. The adaptive components include: a rotating shaft 24, a limiting block 27, a telescopic rod 30, a return spring 29, and a universal ball 31.

[0058] One end of the rotating shaft 24 is inserted into the mounting column 23 and rotates relative to the mounting column 23. A limiting block 27 is fixedly connected to a portion of the rotating shaft 24 inserted into the mounting column 23 and is slidably connected to the limiting groove 26. One end of the rotating shaft 24 has an adjustment groove 28, and the telescopic rod 30 is slidably connected to the adjustment groove 28. One end of the return spring 29 is fixedly connected to the groove wall of the adjustment groove 28, and the other end of the return spring 29 is fixedly connected to the end wall of the telescopic rod 30. A universal ball joint 31 is fixedly connected to one end of the telescopic rod 30, and a neck cushion 25 is ball-jointed to the universal ball joint 31. The side wall of the neck cushion 25 away from the curved rod 22 is curved.

[0059] Work or installation process:

[0060] The user sits directly on the seat cushion 11 and leans back against the chair back 12. By turning the arc rod 22, the user can rotate the arc rod 22 around the mounting axis 21. The user can then adjust the height of the neck cushion 25 in front of the chair back 12 by rotating the arc rod 22 around the mounting axis 21, keeping the height of the neck cushion 25 the same as the height of the user's neck. This is suitable for users of different body types.

[0061] Because the reinforcing rib 18 is made of elastic plastic, it can deform and is elastic. When the user rests their neck on the neck cushion 25, the tilt angle of the neck cushion 25 can be adjusted according to the user's own comfort. Since the telescopic rod 30 is slidably connected in the adjustment groove 28, when the head tilts to one side, the universal ball 31 is in ball contact with the neck cushion 25, and one side of the neck cushion 25 receives more pressure and tilts. The telescopic rod 30 slides into the adjustment groove 28 and compresses the return spring 29. The neck cushion 25 can tilt and deflect, making the seat more ergonomic.

[0062] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
