Abstract
An improved headrest with adjustable connecting tubes is disclosed. The improved headrest comprises a main body, two connecting tubes, a socket unit and several pairs of intermediate connecting tubes. A plurality of threaded insertion holes are provided on the lower side of the main body, and the two connecting tubes may be inserted into these holes. The threaded insertion holes are spaced apart. The rectangular holes allow the adjustment in the distance between the two connecting tubes. The intermediate connecting tubes have several different diameters so that the intermediate connecting tubes may be connected with the bolts provided on the backrests of a seat for different models of automobiles. Hence, by adjusting the distance between the connecting tubes and selecting intermediate connecting tubes with a suitable diameter, the main body may be connected to the backrest of a seat for different models and makes of automobiles.
