Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a seat. Background Art

[0002] Most public chairs are composed of four parts: seat, backrest, armrest and footrest. In general, the footrest and armrest are integrated into a firmly installed armrest frame. The structure is generally steel-wood structure or steel-plastic structure, which is widely used in major auditoriums and theaters.

[0003] Since domestic small-space seats require the overall shape of the seat to be relatively light and thin, this can save return space and reduce the front-to-back distance after returning to its original position, thereby achieving a truly small row spacing. However, the current domestic return mechanism is mainly based on gravity return, or requires a torsion spring + damping return mechanism with an inner iron frame, but the overall size is relatively thick and does not save space.

[0043] On the one hand, referring to Figure 1-Figure 5 , according to the seat of the embodiment of the utility model, comprising:

[0044] The bottom plate 100 includes an inner plate 110 and an outer plate 120, wherein the outer plate 120 is disposed below the inner plate 110;

[0045] The connecting member 200 includes a first surface 210 and a second surface 220, the first surface 210 and the second surface 220 are connected, and the first surface 210 is disposed between the inner plate 110 and the outer plate 120;

[0046] The rotating shaft 300 is rotatably disposed on the second surface 220;

[0047] The torsion spring 400 includes a spiral portion 410 and a torsion rod 420 extending from the spiral portion 410 . The spiral portion 410 is sleeved on the rotating shaft 300 , and the torsion rod 420 abuts against the first surface 210 or the bottom plate 100 .

[0048] The damper 500 is disposed between the connecting member 200 and the rotating shaft 300 .

[0049] According to the embodiments of the present invention, by such a configuration, at least the following effects can be achieved: the base plate 100 includes an inner plate 110 and an outer plate 120; the connecting member 200 is disposed between the inner plate 110 and the outer plate 120; the inner plate 110 and the outer plate 120 clamp and fix the first surface 210, so that the connecting member 200 is stably installed on the base plate 100.

[0050] In some embodiments, it also includes:

[0051] The rotating shaft 300 is rotatably disposed on the second surface 220;

[0052] The torsion spring 400 includes a spiral portion 410 and a torsion rod 420 extending from the spiral portion 410 . The spiral portion 410 is sleeved on the rotating shaft 300 , and the torsion rod 420 abuts against the first surface 210 or the bottom plate 100 .

[0053] The damper 500 is disposed between the connecting member 200 and the rotating shaft 300 .

[0054] Under this setting, the rotating shaft 300 is fixedly arranged on the seat, and the rotating shaft 300 is rotatably arranged on the second surface 220. The base plate 100 and the connecting member 200 can rotate relative to the rotating shaft 300. The torsion rod 420 of the torsion spring 400 abuts against the first surface 210. When the base plate 100 is driven to rotate by an external force, the connecting member 200 rotates together with the base plate 100, so that the torsion rod 420 rotates together. The torsion spring 400 is deformed by the external force. After the external force is removed, the torsion spring 400 restores the driving base plate 100 to its original position due to its deformation recovery ability. The damper 500 is a device that provides resistance to movement and consumes movement energy. It can effectively slow down the rotation speed of the connecting member 200 and avoid excessive rotation speed.

[0055] In some embodiments, the outer plate 120 is provided with a plurality of through holes 121. The through holes 121 can effectively reduce the volume of the chair and save materials. At the same time, the transportation cost can be reduced, the materials used are reduced, the chair becomes lighter, and it is convenient to carry. The through holes 121 increase the surface area, which can effectively increase the fluidity of the airflow, improve the thermal conductivity of the seat, and play a role in heat dissipation.

[0056] In some embodiments, the outer side of the rotating shaft 300 is provided with a locking surface, and the locking surface is parallel to the axis of the rotating shaft 300. The rotating shaft 300 is fixedly connected to the seat, and the corresponding structure of the locking surface and the seat abuts to ensure that the rotating shaft 300 and the seat are relatively fixed, thereby improving the installation stability.

[0057] In some embodiments, a seat cushion 600 is further included, and the seat cushion 600 is arranged on the bottom plate 100. The seat cushion 600 is arranged above the bottom plate 100. The bottom plate 100 has a relatively hard structure, and the overall structure of the seat cushion 600 is relatively soft. The seat cushion 600 is arranged on the bottom plate 100, which can improve the user's riding experience and make it more comfortable.

[0058] In some embodiments, an installation gap 230 is provided between the second surface 220 and the inner panel 110, and the seat cushion 600 is inserted into the installation gap 230. During installation, the connector 200 is inserted between the outer panel 120 and the inner panel 110, so that the connector 200 can be stably installed on the bottom panel 100, and then a part of the structure of the seat cushion 600 is inserted into the installation gap 230, reducing the gap between the internal space and the outside world, so that the seat cushion 600 can be better installed on the bottom panel 100; secondly, the seat cushion 600 can cover the side of the bottom panel 100, and the user will not directly contact the hard bottom panel 100, thereby improving the riding comfort.

[0059] In some embodiments, the seat cushion 600 is provided with an active cavity, and the torsion spring 400 and the connecting member 200 are arranged in the active cavity. The connecting member 200, the damper 500, and the torsion spring 400 are all installed in the active cavity, which facilitates the installation and fixing of the components in the corresponding positions during installation, and is convenient for use.

[0060] In some embodiments, the seat cushion 600 includes a seat cover 610 and seat cotton 620 . The seat cotton 620 is disposed on the bottom plate 100 , and the seat cover 610 is sleeved on the seat cotton 620 .

[0061] In some embodiments, the angle between the first surface 210 and the second surface 220 is set at a right angle. The rotation axis 300 is perpendicular to the second surface 220, and the first surface 210 and the second surface 220 are set at a right angle, so the first surface 210 is parallel to the axis of the rotation axis 300, and the bottom plate 100 structure connected to the first surface 210 is also parallel to the axis of the rotation axis 300, which is convenient for design and installation.

[0062] In some embodiments, a limiting shaft 240 is further included, and the limiting shaft 240 is disposed on the connecting member 200, and the limiting shaft 240 extends along the axial direction of the rotating shaft 300. During the rotation process, the limiting shaft 240 abuts against the seat, which can prevent the seat from continuing to rotate, so that the seat can maintain a flat state, see the overall schematic diagram of the seat.

[0063] The above are only preferred embodiments of the present utility model. The present utility model is not limited to the above implementation modes. As long as the technical effects of the present utility model are achieved by the same means, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles disclosed in the present utility model shall be included in the scope of protection disclosed in the present utility model. They shall all belong to the protection scope of the present utility model. Within the protection scope of the present utility model, its technical scheme and / or implementation mode may have various modifications and changes.
