Benefits of technology

[0004]A primary object of the present invention is to provide a chair structure, which includes movably connected parts and can be converted into a lounge having a curved configuration in compliance with human body's back curve to meet the requirements of body engineering, allowing a user to comfortably lie on the lounge.

Problems solved by technology

Moreover, in the conventional chair, the backrest and the seat are not formed with a curved configuration in compliance with human body's back curve to meet the requirements of body engineering, and there would be a gap existed between the backrest and the seat.
Therefore, even if the backrest of the conventional chair can be angularly adjusted to a fully horizontal position relative to the seat to convert the chair into a lounge, the fully stretched seat and backrest could not provide a curve meeting the requirements of body engineering to comfortably support the waist of a user lying on the lounge.
The user may have a sore waist after lying on the lounge over a long time.
Therefore, the conventional chair is not comfortable in practical use thereof.

Embodiment Construction

[0018]Please refer to FIGS. 1 and 2 that are exploded and assembled perspective views, respectively, of a chair structure according to a first embodiment of the present invention. As shown, the chair structure in the first embodiment of the present invention includes a seat unit 1, a connecting unit 2, a backrest unit 3, and at least two armrests 4.

[0019]The seat unit 1 includes a support leg assembly 11 and a seat 12 connected to a top of the support leg assembly 11. The seat 12 of the seat unit 1 can be a one-piece padded seat.

[0020]The connecting unit 2 is movably connected to the seat unit 1, and includes at least a first linking member 21 and a second linking member 22. The first linking member 21 and the second linking member 22 are movably connected at a first end to each other via two pivot shafts 221. The first linking member 21 is movably connected at a second to a rear edge of the seat 12 via two pivot shafts 211. The first and the second linking member 21, 22 can be two ...

Abstract

A chair structure includes a seat unit having a support leg assembly and a seat; a connecting unit having two linking members and movably connected at one linking member to the seat; a backrest unit movably connected to another linking member of the connecting unit and having a supporting member; and at least two armrests movably connected to two lateral sides of the seat and the backrest units. Each of the armrests has a first and a second movable arm, which are pivotally connected at one end to each other, and at the other end to one lateral side of the seat and the backrest unit, respectively. A stop member is connected to at least one of the two armrests. The chair with movably connected seat unit, connecting unit, backrest unit, and armrests can be converted into a lounge providing a curved configuration in compliance with human body's back curve.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a chair structure, and more particularly to a chair structure which can be converted from a chair into a lounge having a curved configuration in compliance with human body's back curve to meet the requirements of body engineering, so that a user can comfortably lie on the lounge on his back.BACKGROUND OF THE INVENTION[0002]Generally, a conventional chair includes a seat, a backrest movably connected to a rear edge of the seat, and four legs perpendicularly connected to a lower side of the seat. A user can sit on the seat with his or her back leaning on the backrest. The backrest can be adjusted in an inclination angle thereof to convert the chair into a lounge for the user to lean thereon.[0003]While the conventional chair allows a user to sit thereon or convert it into a lounge for leaning, the backrest can usually be adjusted to be half inclined relative to the seat because the backrest is directly movably connected to t...
