Patent ID: 7735923

Claim:
A low-profile tilt control mechanism for a chair having a seat assembly and a back assembly interconnected by said tilt control mechanism such that said back assembly and said seat assembly are rearwardly reclinable from a normal tilt position, said tilt control mechanism comprising a control body and a chair frame member which is pivotally connected to said control body so as to pivot about a horizontal pivot axis during reclining of said seat assembly and said back assembly, said control body including a bottom wall, and said frame member including a control plate which moves in unison with said frame member wherein said control plate includes a plate surface extending in opposing relation with an opposing bottom wall surface of said bottom wall of said control body, said control plate including stop parts which move with said control plate along said bottom wall surface and said tilt control mechanism further including first and second stop mechanisms which are longitudinally elongate so as to lie along said bottom wall of said control body and each respectively having a low-profile engagement section which cooperates with a respective said stop part to selectively confine movement of said control plate and thereby limit movement of said seat assembly and said back assembly; Said first stop mechanism defining a forward tilt control to limit forward tilting of said seat and back assemblies relative to the normal tilt position thereof; and Said second stop mechanism defining a rearward tilt control to limit rearward tilting of said seat and back assemblies relative to the normal tilt position thereof.
