Description

Technical Field

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

[0002] Generally, a seat includes a backrest, a seat cushion and a base. Some seats also include a headrest and a lumbar pad. In order to adjust between the components of the above-mentioned seat so that the seat can adapt to users of different body types, the seats in the prior art usually use the seat cushion as the installation basis, adjustably install the backrest on the seat cushion, and adjust the connection method to install the headrest and the lumbar pad on the backrest, so that the height or angle of the headrest is adjustable, the angle of the backrest is adjustable, and the lumbar pad moves with the backrest.

[0003] For example, the patent application document with the publication number CN115177112A discloses a seat stretching frame and a seat stretching device with arbitrarily adjustable postures, and the connection relationship between the headrest, the backrest and the seat cushion is a sequential connection relationship; the patent with the publication number CN217447135U discloses a chair with a double-fold sunshade structure, and its sunshade part, headrest, backrest and seat cushion are sequentially connected; the patent with the publication number CN217592366U discloses a seat that can be adjusted multifunctionally, and the connection relationship between the headrest, the backrest and the seat cushion is a sequential connection relationship; the patent application document with the publication number CN114587103A discloses an armrest structure and a chair, in which the headrest is installed on the backrest, the backrest is installed on the armrest suspension beam, the armrest suspension beam is installed on the seat cushion, and when the armrest suspension beam moves, the backrest, the headrest and the armrest move simultaneously.

[0004] Since the connection relationship between the headrest, the backrest and the seat cushion is a sequential connection, when the backrest changes its angle, the position of the headrest will also change following the backrest, and the position of the lumbar pad on the backrest will also change with the backrest. The headrest, the backrest and the lumbar pad cannot independently change their positions or angles relative to the seat cushion or the base. Therefore, the adjustment methods of the adjustable components at various positions of the seats in the prior art are relatively limited. Summary of the Utility Model
