- 1. Field of Invention
- The present invention relates to a chair and, more particular, to a reclining apparatus provided between a backrest and a seat.
- 2. Related Prior Art
- As disclosed in Taiwanese Patent Publication No. 526737, a conventional reclining apparatus is provided between a seat and a backrest of a chair. The conventional reclining apparatus includes a
seat support 1, backrest support 2, anadjustment element 3, two links 4 and a lever 7. Theseat support 1 is installed on a post 9 of the chair. The post 9 is a hydraulic cylinder. The backrest support 2 is pivotally connected with theseat support 1. A backrest (marked with “B”) is installed on the backrest support 2. Theadjustment element 3 is provided in theseat support 1 for adjustment of the reclining of the backrest support 2 relative to theseat support 1. The links 4 are provided on two sides of the backrest support 2. A seat (marked with “A”) is installed on the links 4. The lever 7 is partially inserted in theseat support 1. When the lever 7 is operated, the synchronous reclining of the seat and backrest is allowed because of the links 4 and the backrest support 2. - Some problems are encountered with the use of the conventional reclining apparatus. Firstly, the synchronous reclining of the seat and backrest entails the rising of the front edge of the seat. The front edge of the seat presses a user's legs, thus hindering the circulation of blood through the legs. This causes an uncomfortable feeling for the user. The synchronous reclining of the seat and backrest makes the user feel like tumbling backwards. This causes the user panic.
- The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
- According to the present invention, a reclining apparatus is disclosed for a chair that includes a backrest and a seat. The reclining apparatus includes a frame and a linkage installed on the frame in order to support the backrest pivotally and the seat movably so that the seat is kept substantially horizontal when the backrest is reclined.
- The primary advantage of the reclining apparatus of the present invention is the ability to allow the reclining of the backrest while keeping the seat substantially horizontal.
- Other advantages and novel features of the invention will become more apparent from the following detailed description in conjunction with the attached drawings.
- The present invention will be described through detailed illustration of the preferred embodiment referring to the drawings.
