A self-adaptive dental chair seat and rest kit comprises a chair body, a chair back and a head support which are assembled together, wherein the chair body, the chair back and the head support are respectively provided with a skin; the chair is characterized in that the chair body, the chair back and the head supporting piece are both in a sunken shape with high two sides and low middle, each skin is corresponding the chair body, the chair back and the head supporting piece are enclosed to form an inflatable airbag, an inflation hole and an exhaust hole which are communicated with the inflatable airbag are respectively arranged on the lying and leaning surface of the chair body, the chair back and the head supporting piece, and an inflation valve and an exhaust valve are respectively connected to the inflation hole and the exhaust hole.

More preferably, each of the inflatable air bags is correspondingly connected with at least one inflation valve and one exhaust valve respectively; or, the three inflatable air bags are connected to the same inflation valve and the same exhaust valve.

More preferably, the skin is a PU piece.

More preferably, the number of the air-filling holes and the number of the air-discharging holes are plural.

More preferably, the inflation hole and the exhaust hole both include a plurality of holes having different sizes, and the sizes of the inflation hole and the exhaust hole at the middle position are larger than the sizes of the inflation hole and the exhaust hole at the both side positions.

More preferably, a pressure sensor is arranged in the inflatable air bag, and a controller is in signal connection with the pressure sensor, the inflation valve and the exhaust valve.

More preferably, the pressure sensor includes a plurality of pressure sensors positioned on the middle and sides of the reclining surface of the seat body, the seat back, and the head support.

The utility model has the advantages that: the skin and the corresponding kit component form an inflatable air bag with inflation and exhaust holes; during the actual work, open and close and aerify inflation valve, the discharge valve that hole and exhaust hole are connected respectively through the operation button, can aerify and adjust each atmospheric pressure of aerifing in the gasbag for aerifing the gasbag for the shape of gasbag and different patients' weight, size match can provide a softer more, more comfortable lying for different patients and lean on, and human parcel nature is better, effectively improves patient experience. Particularly, after the pressure sensor is additionally arranged in the inflatable air bag, the automatic adjustment of the air pressure in the inflatable air bag can be realized, and the use is more convenient.

Detailed Description

The following description will be further made in conjunction with the accompanying drawings of the specification, so that the technical solution and the advantages of the present invention are clearer and clearer. The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.

Additional aspects and advantages of the invention will be set forth in part in the description which follows, or may be learned by practice of the invention.

As shown in fig. 1, an adaptive dental chair seat and back kit comprises a chair body 1, a chair back 2 and a head support 3 which are assembled together, wherein skins are respectively arranged on the chair body 1, the chair back 2 and the head support 3; its characterized in that, chair body 1 the back of the chair 2 with head support piece 3 all is the sunken form that the high centre in both sides is low, each the covering with corresponding chair body 1 the back of the chair 2 with head support 3 encloses into inflatable airbag chair body 1 the back of the chair 2 with head support piece 3 lie on the face of leaning on be equipped with respectively with corresponding inflatable air bag intercommunication inflate hole 4, exhaust hole 5 inflatable air hole 4 with be connected with respectively on the exhaust hole 5 inflate valve 6 with discharge valve 7.

During the actual work, open and close inflation valve 6, discharge valve 7 through the operation button, and then aerify and adjust each atmospheric pressure of aerifing in the gasbag for aerifing the gasbag for the shape of gasbag and different patients' weight, size match, can provide a softer more, more comfortable lying for different patients and lean on, and human parcel nature is better, effectively improves patient experience.

In this embodiment, it is preferable that each of the inflatable air bags corresponds to at least one of the inflation valve 6 and the deflation valve 7, so as to adjust the air pressure. Preferably, the skin is a PU part, so that the elasticity is good and the leather-like design is convenient to carry out. In other embodiments, three of the inflatable bladders are controlled by the same inflation valve and the same exhaust valve; the present embodiment is not limited.
