Description

Multifunctional seats with electric control

The present invention relates to an office chair, and more particularly to a multifunctional chair which can be electrically controlled.

An office chair refers to a chair that is used for the convenience of daily work and social activities. Nowadays, an office chair must not only meet the normal use of users during work. Due to 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.

Although some manufacturers have made manual sit-and-lean office chairs, their shortcomings are:

1. A manual sit-and-lie office chair requires the user to pull out the footrest and adjust the chair back angle separately, which is more complicated to operate.

2. As mentioned above, since the footrest and the chair back are operated separately, sometimes the center of gravity is unstable and it may tip over.

3. The office chair has only two functions: sitting and lying down, and no other functions.

The main purpose of the present invention is to provide a multifunctional seat that can be electrically controlled. The electric control device drives a connecting rod mechanism installed at the lower end of the seat to allow the seat footrest and the seat back to move simultaneously, thereby achieving the effect of synchronous adjustment of sitting and lying.

To achieve the above purpose, the structure of the present invention comprises a swivel leg frame 1, a seat 2, a seat back 3 and a footrest 4 which can be tilted and unfolded from the lower end of the seat 2;

The swivel foot frame 1 is connected under the seat 2, and the swivel foot frame 1 provides the seat 2 with rotation;

The seat 2 is a component for the user to sit on;

A driving device 5 is provided below the seat 2;

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

The aforementioned chair back 3 is disposed on one side of the 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;

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 synchronously produce a tilted lying effect.

Through the above description, the features and effects of this new type are briefly described as follows:

1. The structure provided by the present invention can adjust the tilt angle of the chair back 3 while unfolding the foot pad 4, so that the user can quickly adjust the seat angle when taking a rest.
