ABSTRACT:
A hinge joint for use in the seat of a motor vehicle to pivotally connect the back rest to the body supporting portion has first and second leaves which are affixed to the body supporting portion and to the back rest, respectively, and a pintle which can be rotated by a wheel or by a motor and carries an eccentric installed in an opening of one of the leaves. The eccentric is assembled of two spring-biased arcuate mirror symmetrical sections and a sickle-shaped centering section. The other leaf is rotatably mounted on the pintle. When the pintle is rotated, an arm or a lobe of a motion transmitting member which is affixed to the pintle first disengages the two mirror symmetrical sections from the one leaf so that the one leaf is thereupon engaged only by the centering section while the teeth of an internal gear on one of the leaves roll along the teeth of a spur gear on the other of the leaves.
