ABSTRACT:
A headrest includes an L-shaped board and a casing, both of which pivotally clamp a shaft extending transversely between the board and the casing. Two tubular members are movably mounted on the shaft and each has a tube, which extends through the bottom of the board. Each of the tubes has a positioning rod connected thereto, which extends into the seat and is engaged with the engaging device in the seat. Each of the positioning rods has a plurality of notches defined therein and is connected to one of the two respective tubes by bolts extending through the tubes and contacting against the positioning rods. The distance between the positioning rods can be adjusted by moving the tubular members, and the two positioning rods can be rotated by releasing the bolts so as to engage with different engaging devices.
