Abstract: A vehicle seat having at least one hinge fitting, the upper fitting element (10) of which is associated with the backrest (11) and the lower fitting element of which is associated with the seat frame, has a hook (14) which is arranged so as to be pivotable in a suspended manner, runs parallel to the hinge axle in its locked position, and securely engages behind lock bolts (29) to be connected with the floor of the vehicle. The upper fitting element (10) has a detent (28) in a surface (27) that extends in its pivot direction. A counter detent (22') is provided at one end of a double-armed pivot lever (20), which is pivotably mounted on the lower fitting element and is spring-loaded in the sense of moving the counter detent (22') toward the detent (28). The detent (28) and the counter detent (22') are in engagement in an angular position of the upper fitting element (10) that lies outside of the use position of the backrest ( 11), and form a form-fitting pivot block for the upper fitting element (10).
