A reclining chair system with a standard assembly supporting seat and backrest assemblies, which are pivotally mounted to each other and capable of providing a rocker effect to a user. A strut assembly provides substantially a bounce free shock absorbing function by using two coaxially disposed compressible and resilient members that are compressed sequentially. A headed shaft with a step limits the compression of the first member. The arrangement permits a volumetrically efficient operation while preventing excessive fatigue of the member. An adjustment mechanism permits a user to readily set the relative angular position of backrest and seat with respect to the standard (and consequently the horizontal plane) depending on the location of the chair system.

1. A reclining chair system, comprising:A) a seat assembly having front, rear and two lateral sides each of said lateral sides including a perpendicularly mounted rocker pin;B) an L-shape backrest assembly having lower and upper portions substantially perpendicular to each other and said backrest assembly being pivotally mounted to said seat assembly, said lower portion cooperatively coacting with said rocker pin to cause said seat assembly to move angularly in proportion with a backward angular movement of said upper portion thereby achieving a rocker effect;C) a standard assembly;D) supporting means including an L-shape member having first and second perpendicularly disposed arms, said first arm being pivotally mounted to said seat assembly and to said lower portion, said first arm being rigidly mounted to said standard assembly, and said second arm having a distal end mounted to said standard assembly, said supporting means further including first and second stopper means for limiting the rotation between two extreme positions of said seat and backrest assemblies, respectively, with respect to said supporting means; andE) a strut assembly having first and second ends, said first end being pivotally mounted to said lower portion at a point separated a predetermined distance from the pivoting point of said supporting means with said seat and backrest assemblies, and said second end being mounted to said second arm.2. The reclining chair system set forth in claim 1 wherein said strut assembly includes first and second compressible and resilient members, abuttingly and coaxially disposed with respect to each other wherein the distal ends of said first and second compressible and resilient members define said first and second ends of said strut assembly.3. The reclining chair system set forth in claim 2 wherein said strut assembly includes first and second spacers at said distal ends.4. The reclining chair system set forth in claim 3 wherein said strut assembly includes a central spacer between said first and second resilient members.5. The reclining chair system set forth in claim 4 wherein said first and second spacers, first and second compressible and resilient members and said central spacer include each a coaxially aligned central through opening and said strut assembly further includes an elongated shaft having a headed end and a distal termination, said shaft being receivable through said coaxially aligned central through opening and said headed termination being cooperatively disposed to coact with said first spacer and said header termination defining said first end of said strut assembly.6. The reclining chair system set forth in claim 5 wherein said shaft includes a step defining first and second shaft portions, said first shaft portion being adjacent to said distal termination and having a smaller diameter than said second shaft portion, and said central spacer having a diameter smaller than said second shaft portion but larger than the diameter of said first shaft portion, said step cooperatively coacting to prevent further compression of said first compressible and resilient member beyond a predetermined magnitude.7. The reclining chair system set forth in claim 6 wherein the compression of said first and second compressible and resilient members cause the latter to expand laterally and coact with said first and second shaft portions, respectively, thereby providing a gripping action that stabilizes the relative position of said shaft.8. The reclining chair system set forth in claim 1 further including adjusting means for changing the relative position of said supporting means with respect to said standard assembly thereby adjusting the angular position of said backrest and seat assemblies with respect to said standard assembly.9. The reclining chair system set forth in claim 8 wherein said adjusting means includes a plate with third and fourth ends and first and second surfaces, including at least two through holes positioned adjacent to said third end and a first pin perpendicularly mounted on said first surface adjacent to said fourth end and a second pin perpendicularly mounted to said second surface at a predetermined distance between said through holes and said first pin, said first pin being mounted to said standard assembly said second pin cooperatively coacting with said supporting means and further including fastening means that cooperate with said through holes to set said adjusting means at selected predetermined positions so that the relative position of said supporting means with respect to said standard is adjusted.
