ABSTRACT:
A hinge joint wherein a first component is affixed to the body supporting portion and a second component is affixed to the back rest of a seat, particularly in a motor vehicle. The two components are articulately connected to each other by a pintle having a cylindrical portion journalled in a sleeve of the second component, and an eccentric conical portion journalled in a complementary hole of a spur gear forming part of the first component. A spring biases the conical portion into the hole, and the conical portion has an eccentric recess for a cylindrical portion of the sleeve. Such design of the pintle contributes to simplicity and to a reduction of space requirements of the hinge joint. The conical portion can move the spur gear of the first component radially relative to an internal gear of the second component when the pintle is rotated by a hand wheel or by a motor.
