In places such as auditoriums, movie theaters, auditoriums, reporting halls, the cushion 2100 that generally needs the chair can kick-back to personnel's admission and evacuation can also conveniently clean ground. In the related art, there is an auditorium chair 2000 whose seat cushion 2100 is automatically rebounded to be reset in a manner of a spring, and the seat cushion 2100 is reset to a vertical state by elastic deformation of the spring. However, this spring-loaded approach may cause the seat pad 2100 to generate a loud noise during the rebound process, which may be a poor user experience.

In order to solve the above problem, referring to fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides a swiveling device 1000, where fig. 1 is a schematic view of the swiveling device 1000 used in cooperation with a seat, fig. 2 is a schematic view of an overall structure of the swiveling device 1000, and fig. 3 is a schematic view of the swiveling component 200 located at another position. The swivel device 1000 is used for seating furniture, in particular an auditorium chair 2000, which will be illustrated later by way of example as auditorium chair 2000. The swivel device 1000 can reposition the seat 2100 of the auditorium chair 2000. In the embodiment of the present invention, the term "reset" refers to returning the seat cushion 2100 to the folded state when the auditorium chair 2000 is not used by the user, that is, the seat cushion 2100 is in the substantially vertical state (refer to the state shown in fig. 1). In the embodiments of the present invention, the term "substantially vertical" may be interpreted as vertical, nearly vertical, or having a predetermined angle.

Referring to fig. 3 and 4, in some embodiments, the swivel device 1000 includes a base 100, a rotation member 200, a torsion spring 300, and a damper 400. The base 100 is fixedly coupled to the seat back 2200 to determine the relative position of the swivel device 1000 and the auditorium chair 2000. The rotatable member 200 is rotatably coupled to the base 100, and the rotatable member 200 is also fixedly coupled to the seat cushion 2100, such that the seat cushion 2100 is rotatably coupled to the base 100 via the rotatable member 200. The rotation member 200 has a support state and a folded state, and when the user sits on the seat cushion 2100, the rotation member 200 is in the support state, for example, the state shown in fig. 3; when the seat cushion 2100 needs to be folded for other persons to exit after the user is out of the seat, the rotating member 200 is in a folded state, such as the state shown in fig. 1 and 2.
