ABSTRACT:
The adjustable hinge mount for seats having a reclinable backrest includes a pivot axle rigidly connected at one end thereof to the hinge mount member assigned to the seat proper and supporting for rotation an eccentric disk which in turn supports the tiltable hinge mount member assigned to the backrest and being formed with a spur gear which engages the inner gear of the wobble gear assembly formed on the seat hinge mount. The threaded pin of the pivot axle engages a locking nut controlled by a spring biased and hand operated lever which normally brings the locking nut into engagement with the face of the eccentric disk and rigidly connects the same to the pivot axle so that the reclinable backrest is arrested in its adjusted angular position.
