Example Embodiment

[0078] Example 1: The present invention provides a dynamic seat, such as Figure 1-18 Shown, including:

[0079] The first base 2 is configured to be connected to the seat support assembly 1. The first base 2 includes a bottom plate 21 and a front plate 22 and a rear plate 23 extending upward from the front and rear ends of the bottom plate 21. The front plate 22 , The rear plate 23 plays a supporting role; the seat support assembly 1 includes a support rod 11 and a support foot (not shown), a socket 12 is correspondingly provided on the bottom plate 21, and the support rod 11 is arranged in the socket 12 , The support rod 11 and the support feet are standing on the ground, so in addition to rotating in the circumferential direction, the first base 2 is horizontally fixed relative to the ground, that is, it cannot swing left and right or tilt back and forth.

[0080] It also includes a second base 3 that is separated from the first base 2. The second base 3 is configured to rotate ...

Example Embodiment

[0101] Example 2: The difference from Example 1 is that Figure 19 As shown, the two elastic transfer connectors 51 in this embodiment are independent components, so that the design is convenient for layout, and on the basis of meeting requirements, materials are saved and costs are reduced.

Example Embodiment

[0102] Embodiment 3: The difference from Embodiment 1 is that the second base 3 rotates around the first base 2 through a rotating shaft 33, which is a whole long shaft. The swing reset mechanism in this embodiment is a sleeve There are two torsion springs (not shown) on the shaft 33. One torsion arm of the torsion spring is connected to the base, and the other torsion arm of the torsion spring is connected to the left or right side of the top plate 31; this is achieved by a torsion spring. The rotation of the second base 3 is reset.

Abstract

The invention relates to a dynamic seat. The dynamic seat comprise a first base; a second base that turns to left or right relative to the first base; a seat support member configured to support a human body when sitting; a first crank of which one end is hinged to the first base and the other end is rotatably connected to the seat support member, wherein a rotatable connection between the first crank and the seat support member is flexible; a second crank of which the two ends are hinged to the second base and the seat support member respectively; and a rocker configured to connect a seat back assembly and integrate with the second crank. The first crank, the seat support member, the second crank, the first base and the second base constitute a four-link mechanism. When the seat support member and the second base jointly turns to left or right around the first base, the rotatable connection between the first crank and the seat support member is deformed under action of a torsional force transmitted by the seat support member, and restored to an original state in case of disappearance of the torsional force. A user can swing left and right or lean forward and backward, so that thedynamic seat meets different postures of the user.

Description

technical field [0001] The invention relates to the field of seats, in particular to a dynamic seat. Background technique [0002] Seat is a kind of seat, which is widely used in people's work and life, and is generally recognized and loved by people. It is one of the indispensable furniture in modern office and home environment; the traditional seat back is generally One, and most of them are fixed, that is, the position of the chair back is fixed, and the position will not change as the user's sitting posture changes. [0003] Since the human body will change various postures when sitting, it is necessary for the back of the chair to move back and forth following the back of the human body to make the back of the human body feel more comfortable; Adaptive seat. [0004] For example: Patent No. CN201620938636.5 discloses "an adaptive backrest seat", including a backrest, the backrest includes a shoulder resting part and an arc-protruded waist resting part, and also includ...
