ABSTRACT:
A positioning device includes a clamping seat having two clamping members having clamping portions mounted around a fixed rod of a chair having an inclinable seat to which one of the clamping members is fixed. An adjusting rod includes a coupling seat and a handle fixed to the coupling seat. The coupling seat includes a positioning groove having a low-profile section and a high-profile section. A positioning block is mounted to the other clamping member and includes a protrusion received in the positioning groove. When the protrusion is engaged with the low-profile section, the clamping portions are not clamped on the fixed rod, allowing movement of the clamping seat along the fixed rod. When the handle is moved to a clamping position, the protrusion is engaged with the high-profile section, the clamping portions are clamped on the fixed rod, not allowing movement of the clamping seat along the fixed rod.
