Hinge joint for use in the seats of motor vehicles and the like

摘要: A hinge joint for use between the body supporting portion and pivotable back rest of a seat has first leaf which is affixed to portion, second rest, pintle pivotably connects leaf. In order reduce friction during pivoting leaf, latter provided with sleeve-like central surrounded by an antifriction bearing installed in cylindrical cupped motion transmitting member pintle. smaller-diameter two wedge-like arcuate sections are biased torsion spring against internal surface radial play leaves. Friction external surfaces can be reduced coating some or all these lubricant. Such lubricant also used annular centering element within axially adjacent sections. addition, providing and/or facets recesses.
