In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0038] According to a first aspect of the present invention, a dental chair bearing kit is provided, which includes an elastic component and a supporting component.

[0039] Hereinafter, the specific structures of the above components of the dental chair carrying kit according to this embodiment will be described.

[0040] In this embodiment, if Figures 2 to 4 As shown, the elastic component is connected to the support component. The elastic component ensures the patient's comfort when lying down, while the support component provides the patient with a certain degree of support. Specifically, the elastic component includes a stacked elastic member 10 and a protective member 20. The elastic member 10 can be a shaped sponge, and the protective member 20 can be a PU leather. The protective member 20 is arranged on the side facing the patient, that is, the protective member 20 is arranged on the top of the dental chair support kit. The protective member 20 covers the surface of the elastic member 10 facing the patient and conforms to the shape of the elastic member 10 to protect the elastic member 10 and extend the service life of the dental chair support kit.

[0041] More specifically, if Figures 2 to 4As shown, the support assembly includes a first bearing member 30, a second bearing member 40 and an inflatable member 50. The first bearing member 30 and the second bearing member 40 are both formed into a plate-like structure. The inflatable member 50 can be an airbag. The first bearing member 30 is arranged on the side of the support assembly away from the elastic component, that is, the first bearing member 30 is arranged at the bottom of the dental chair bearing kit, and the second bearing member 40 is arranged on the side of the support assembly close to the elastic member 10. An extrusion position 41 is formed on the second bearing member 40. The inflatable member 50 is installed on the first bearing member 30. The inflatable member 50 is inflated to compress part of the elastic member 10 through the extrusion position 41. The patient lies on the dental chair bearing. After the kit is put on, since the elastic part 10 has been compressed under the action of the expansion of the inflatable part 50, the degree of depression at the compression and extrusion position 41 when the patient lies down is smaller than the degree of depression at the positions around the extrusion position 41, that is, the force applied to the dental chair support kit after the patient lies down has little effect on the deformation of the elastic part 10 at the extrusion position 41, thereby relatively improving the hardness of the extrusion position 41, thereby providing effective support to the position where the patient needs support; in addition, the support height can be adjusted by adjusting the degree of expansion of the inflatable part 50 to meet the usage needs of different patients, thereby improving the comfort of patients when lying for a long time.

[0042] It should be noted that the inflatable member 50 can be connected to an air supply device such as an air pump to adjust the inflation or deflation of the inflatable member 50. It should be further noted that after the inflatable member 50 is inflated, the protrusion height of the side of the dental chair support kit where the protective member 20 is located is actually not very high before the patient lies down. However, the inflated inflatable member 50 inside the dental chair support kit has compressed the elastic member 10, making the hardness of the compression position 41 of the dental chair support kit relatively harder than other positions outside the compression position 41. As a result, the compression position 41 can provide stronger support for the patient after the patient lies down.

[0043] In a preferred embodiment, the squeezing position 41 is arranged at a position corresponding to the patient's waist, so as to support the patient's waist when the patient lies down, thereby improving the patient's comfort when lying down for a long time.

[0044] Preferably, if Figure 1 As shown, the protective member 20 is fixed to the first supporting member 30, thereby protecting all components arranged inside the dental chair supporting kit, improving the aesthetics of the dental chair supporting kit and the comfort of patients.

[0045] Preferably, the first support member 30 is a rigid member, such as a high-strength metal material, such as cast iron, to provide excellent load-bearing properties, allowing it to support the weight of the patient when leaning or sitting, while ensuring that the dental chair support assembly does not deform. The second support member 40 can be a plastic member, which not only provides reliable support and fixation for the elastic component but also facilitates injection molding. It should be noted that plastic also has a certain strength and is difficult to deform under normal pressure.

[0046] In this embodiment, the inflatable member 50 is made of a combination of TPU (thermoplastic polyurethane) and nylon to provide excellent wear resistance and extend the service life of the inflatable member 50. Preferably, the inflatable member 50 is a plate-like structure when not inflated to avoid occupying the thickness of the dental chair support kit.

[0047] In a first alternative embodiment, as Figure 4 As shown, the second carrier 40 is an integrally formed injection molding structure. The main body of the second carrier 40 is the structural part of the second carrier 40 excluding the extrusion position 41. The extrusion position 41 is installed with a supporting plate 411 and a connecting rib 412. There is a gap between the supporting plate 411 and the main body of the second carrier 40. The connecting rib 412 connects the supporting plate 411 and the main body of the second carrier 40 respectively. The supporting plate 411 is a plate-like structure and the connecting rib 412 is a strip-like structure. Since the connection area between the supporting plate 411 and the main body of the second carrier 40 is small and the second carrier 40 is formed by injection molding, the supporting plate 411 can be relatively close to the second carrier. 40 is movable, and the inflatable part 50 is in contact with the supporting plate 411, so that after the inflatable part 50 is inflated, it can push the supporting plate 411 to move in the direction close to the elastic part 10, thereby squeezing the elastic part 10 and compressing the elastic part 10. The number of connecting ribs 412 can be one or more. When the number of connecting ribs 412 is more than one, the multiple connecting ribs 412 are arranged around the circumferential interval with the supporting plate 411. It should be noted that the number of connecting ribs 412 needs to ensure that the supporting plate 411 can apply a force to the elastic part 10 when the inflatable part 50 is inflated, so as to ensure that the elastic part 10 is compressed and deformed.

[0048] In a second optional embodiment, the extrusion position 41 is provided with a through hole. After the inflatable member 50 is inflated, at least part of the inflatable member 50 passes through the extrusion position 41 to extrude the elastic member 10, thereby achieving direct extrusion deformation of the elastic member 10 by the inflatable member 50.

[0049] In a third optional embodiment, the extrusion position 41 is provided with a through-hole structure, and the dental chair bearing kit further includes a support member embedded in the through-hole of the extrusion position 41. The support member may be a plate-like structure. Preferably, the mechanical structure strength of the support member is greater than the mechanical structure strength of the second bearing member 40. The support member may be a rigid plate, such as a steel plate, to ensure that the elastic member 10 forms an effective compression amount after the inflatable member 50 is expanded. There is no connection between the support member and the second bearing member 40, that is, the support member is not connected to the second bearing member 40. The extrusion position 41 only serves to limit the support member. The inflatable member 50 abuts against the support member, so that the inflatable member 50 can push the support member to squeeze the elastic member 10 after inflation to achieve compression deformation of the elastic member 10.

[0050] Furthermore, if Figures 2 to 4 As shown, a support platform 31 is formed on the first carrier 30, protruding toward the extrusion position 41. The support platform 31 can be a block-shaped structure or a plate-shaped structure spaced apart from the first carrier 30. The surface of the support platform 31 facing the inflatable member 50 is flat, facilitating the installation of the inflatable member 50 on the support platform 31. This allows the inflatable member 50 to be positioned closer to the elastic member 10, facilitating the compression of the elastic member 10 by the inflatable member 50 after expansion. In this embodiment, the inflatable member 50 can have an inflation area formed in the middle and openings provided around the periphery to facilitate fastening to the support platform 31 with fasteners such as screws.

[0051] In this embodiment, if Figures 2 to 6 As shown, the dental chair support kit also includes a heater 60 sandwiched between the elastic member 10 and the protective member 20 to prevent the protective member 20's surface temperature from being low and affecting the patient's comfort. Specifically, the heater 60 can be a heating pad with an internal heating wire. The heater 60 is flexible and conforms to the elastic member 10, preventing discomfort to the patient while lying down. Furthermore, an electrical circuit is connected to the end of the heater 60 to enable heating. Preferably, the heater 60 includes a circuit board to facilitate control of heating and the heating temperature.

[0052] Furthermore, in this embodiment, Figure 5 and Figure 6 As shown, a vibration module 70 is provided on the heating element 60. The vibration module 70 can be one or more small sheet-shaped vibrators, or a vibration motor, to provide a massage effect, thereby relieving the patient's tension during treatment. Preferably, the vibration module 70 includes multiple vibrators or vibration motors arranged in an array. The vibration module 70 can be connected to the circuit board described above to facilitate control of activation and vibration frequency.

[0053] Furthermore, in this embodiment, a flexible layer is provided between the protective member 20 and the heating member 60. The flexible layer may be a cotton layer, so that the vibration module 70 can be flattened, preventing protruding marks from being seen on the surface of the protective member 20, and further improving the patient's comfort.

[0054] In this embodiment, the dental chair support kit includes a back cushion for back support and a seat cushion for buttocks support. Specifically, the dental chair support kit comprises a two-part structure: a back cushion and a seat cushion. The back cushion and the seat cushion can be separated or integrated. In a preferred embodiment, both the back cushion and the seat cushion include the elastic component, heater 60, vibration module 70, first support member 30, and second support member 40 as described above. However, the inflatable member 50 is only located in the back cushion, ensuring effective lumbar support while reducing costs.

[0055] Furthermore, in this embodiment, Figure 5 and Figure 6 As shown, the area of ​​the heater 60 in the seat cushion is larger than that in the back cushion, allowing the heater 60 on the seat cushion to extend from the patient's buttocks to the legs, thereby achieving comprehensive heating and ensuring the patient's overall comfort. Optionally, the heater 60 in the back cushion is a rectangular structure measuring 320mm x 300mm, while the heater 60 in the seat cushion is a rectangular structure measuring 700mm x 330mm.

[0056] According to the dental chair bearing kit of the present invention, the second bearing member is arranged on the side of the bearing assembly facing the elastic member, and an extrusion position is formed on the second bearing member. The inflatable member is clamped between the extrusion position and the first bearing member. The inflatable member is inflated and expanded to increase its volume to compress part of the elastic member. After the patient lies on the dental chair bearing kit, the elastic member has been compressed under the action of the expansion of the inflatable member, so that the force applied by the patient after lying down has less effect on the deformation of the elastic member at the extrusion position, thereby relatively improving the hardness of the extrusion position, thereby providing effective support to the position where the patient needs support; in addition, the support height can be adjusted by adjusting the expansion degree of the inflatable member to meet the usage needs of different patients, thereby improving the comfort of the patient when lying for a long time.

[0057] A dental chair provided by the present invention includes the dental chair bearing kit described above, and thus has all the beneficial effects of the dental chair bearing kit, which will not be described in detail here.

[0058] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
