ABSTRACT:
A joint for adjustably mounting a backrest support on a stroller frame. The joint consists of a first element and a second element. The first element has (a) an arc-shaped edge, (b) a hole formed transversely through the first element, (c) two bosses formed on a side of the first element, for which the hole is the middle point, (d) a flange formed along the arc-shaped edge, (e) a number of teeth formed on the flange and (f) a pocket for receiving the backrest support. The second element has (a) a tubular body for receiving a handle, (b) a clamp formed below the tubular body, for receiving a rear wheel leg, (c) a plate with an arc-shaped rim, being formed on a side of the tubular body, (d) a passage formed transversely through the plate and the tubular body, (e) two slots formed in the plate and (f) a number of recesses formed in the arc-shaped rim. A rivet penetrates a hole in a seat support, the hole in the first element, the passage in the second element and a hole in the handle. The teeth are received in corresponding recesses, for retaining the backrest support in a desired position. The bosses are received in the slots, for restraining rotation of the first element with respect to the second element within a certain degree.
