摘要

Motor-vehicle door lock (1) having a rotary latch (3) rotatable about a rotary-latch bolt (2) and a blocking-pawl arrangement (5, 6) pivotable about a bearing bolt (4), in which, in the closed state of the motor-vehicle door, a lock holder (7) fastened to the door post engages into a lock-holder recess of the rotary latch (3), and in which, in the closed state of the motor-vehicle door, the blocking-pawl arrangement (5, 6) engages with fitting-surface contact by means of a blocking surface (8) behind a counter blocking surface (9) on the rotary latch (3) in the blocking position of the blocking-pawl arrangement (5, 6). The blocking-pawl arrangement (5, 6) is designed as a lever mechanism having a lever (5), located on the same side as the bearing bolt and pivotable about the bearing bolt (4), and a lever (6) carrying the blocking surface (8). The two levers (5, 6) are combined so as to be foldable relative to one another by means of a blocking-pawl joint (10) having a joint axis parallel to the bearing bolt (4). The lever (6) carrying the blocking surface (8) has a blocking-surface lever arm (11), a lever arm (12) located on the same side as the bearing bolt and, on the lever arm (12) located on the same side as the bearing bolt, a bearing-bolt receptacle (13) with switching play between a blocking-position stop (14) and a folding stop (15). During an opening movement of the blocking-pawl arrangement (5, 6), with the motor-vehicle door closed, the lever (6) carrying the blocking surface (8) folds relative to the lever (5) located on the same side as the bolt. The blocking-position stop (14) comes free from the bearing bolt (4). The folding stop (15) comes to bear on the bearing bolt (4). The fitting-surface contact can thereby be changed over to a linear contact (16). ……
