ABSTRACT:
A folding linkage, especially for a folding chair, has four pivoting bars. In the open position the first bar forms one side of a triangle. The second and third bars are colinear to form a second side of the triangle and the fourth bar forms the third side of a triangle in the closed position the four bars are substantially aligned. The fourth bar is joined to the first bar by a pivot which moves along a curved path.
