Description

Technical Field

[0001] The utility model relates to an office chair, in particular to a multifunctional chair which can be electrically controlled. Background Art

[0002] An office chair refers to a chair that is equipped for the convenience of work in daily work and social activities. Nowadays, office chairs must not only meet the normal use of users during work, but also because of the limited space in the office, when taking a lunch break or needing a rest, most people lie on the table to rest, but this will affect digestion, and the blood circulation in the buttocks and legs will be poor, resulting in numbness in the feet.

[0003] Although some manufacturers have produced manual sitting and lying office chairs, the disadvantages are:

[0004] 1. A manual sitting / lying office chair requires the user to pull out the foot pad and adjust the chair back angle separately, which is more complicated to operate.

[0005] 2. Based on the above, since the foot pad and the chair back are operated separately, sometimes the center of gravity is unstable and it may cause overturning.

[0006] 3. The office chair has only two functions: sitting and lying down, and has no other functions. Utility Model Content

[0007] The main purpose of the utility model is to provide a multifunctional seat that can be electrically controlled, using an electric control device to drive a connecting rod mechanism installed at the lower end of the seat, so that the seat foot pad and the seat back can move at the same time, achieving the effect of synchronous adjustment of sitting and lying.

[0008] To achieve the above-mentioned purpose, the structure of the utility model comprises a rotating foot frame 1, a seat 2, a chair back 3 and a foot pad 4 which can be tilted and unfolded from the lower end of the seat 2;

[0009] The rotating footstand 1 is connected under the seat 2, and the rotating footstand 1 allows the seat 2 to rotate;

[0010] The seat 2 provides a component for the user to sit on;

[0011] A driving device 5 is provided under the seat 2;

[0012] The seat 2 and the foot pad 4 are connected via a connecting rod set 6, and the driving device 5 is used to drive the connecting rod set 6 so that the foot pad 4 can be tilted and unfolded from the seat 2;

[0013] The aforementioned chair back 3 is disposed on one side of the chair seat 2, and the chair back 3 is pivotally connected to a sliding plate 31, and the sliding plate 31 is also connected to the driving device 5;

[0014] Accordingly, the driving device 5 is controlled by a controller 7 so that the foot pad 4 is driven by the driving device 5 to be flipped from under the seat 2, and the driving device 5 simultaneously drives the sliding plate 31 to move, so that the chair back 3 can simultaneously produce a tilted lying effect.

[0015] Through the above description, the features and effects of the utility model are briefly described as follows:

[0016] 1. The structure provided by the utility model can adjust the inclination angle of the chair back 3 when the foot pad 4 is unfolded, so that the user can quickly adjust the seat angle when taking a rest.

[0017] 2. The structure provided by the utility model can adjust the inclination angles of the chair back 3 and the foot pad 4 simultaneously, which can avoid the problem of the chair tipping over due to the unstable center of gravity. BRIEF DESCRIPTION OF THE DRAWINGS
