A hinge assembly for supporting the back part of a motor-vehicle seat on the fixed seat part comprises two hinges. Each of these hinges comprises a first hinge element pivotal on the seat part about a first axis between a rest position and a pivoted position and a second hinge element on the back part and pivotal on the respective first hinge element about a second axis through a plurality of angularly offset adjustment positions. Each second hinge element is provided with a plurality of teeth and each first hinge element has a pivotal pawl with teeth engageable with the teeth of the respective second element so as to hold the second element when these teeth are engaged in any of a plurality of angularly off-set adjustment positions. Mechanism is provided connected to both of these pawls for displacing the teeth thereof into and out of engagement with the respective teeth of the second formation. In addition a cam is provided which serves to lock out the adjustment means when the back part of the seat and the corresponding second hinge elements have been pivoted from the rest position, so that when the seat back has been pivoted forwardly the adjustment mechanism cannot be operated to maladjust the seat.
