BACKGROUND OF INVENTION [0001] 1. Field of Invention [0002] The present invention relates to a chair and, more particular, to a reclining apparatus provided between a backrest and a seat. [0003] 2. Related Prior Art [0004] 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, an adjustment element 3, two links 4 and a lever 7. The seat 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 the seat support 1. A backrest (marked with "B") is installed on the backrest support 2. The adjustment element 3 is provided in the seat support 1 for adjustment of the reclining of the backrest support 2 relative to the seat 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 the seat 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. [0005] 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. [0006] The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art. SUMMARY OF INVENTION [0007] 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. [0008] 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. [0009] Other advantages and novel features of the invention will become more apparent from the following detailed description in conjunction with the attached drawings. BRIEF DESCRIPTION OF DRAWINGS [0010] The present invention will be described through detailed illustration of the preferred embodiment referring to the drawings. [0011] FIG. 1 is a side view of a chair equipped with a reclining apparatus according to the preferred embodiment of the present invention. [0012] FIG. 2 is a perspective view of a backrest and a seat of the chair detached from the reclining apparatus shown in FIG. 1. [0013] FIG. 3 is an enlarged exploded view of the reclining apparatus shown in FIG. 2. [0014] FIG. 4 is a cross-sectional view of the chair shown in FIG. 1. [0015] FIG. 5 is a top view of the reclining apparatus shown in FIG. 4. [0016] FIG. 6 is similar to FIG. 4 but shows the chair in a different position. [0017] FIG. 7 is a top view of the reclining apparatus shown in FIG. 6. [0018] FIG. 8 is similar to FIG. 1 but shows the chair in a different position. [0019] FIG. 9 is similar to FIG. 8 but shows the chair in a different position. DETAILED DESCRIPTION OF PREFERRED EMBODIMENT [0020] Referring to FIG. 1, a chair includes a post 61, a backrest 62 and a seat 63. The post 61, the backrest 62 and the seat 63 are all connected with a reclining apparatus according to the preferred embodiment of the present invention. The reclining apparatus includes a frame 10, a linkage 20, an adjusting device 30 and a positioning device 40. The frame 10 is installed on the post 61. The linkage 20 is installed on the frame 10 in order to support the backrest 62 pivotally and the seat 63 movably. The adjusting device 30 is provided between the frame 10 and the linkage 20 in order to adjust resistance against the reclining of the backrest 62. The positioning device 40 is provided between the backrest 62 and the seat 63 in order to determine the position of the backrest 62 relative to the seat 63. Continue reading about Chair...
