Abstract

The present invention relates to a door lock device for a motor vehicle door, comprising: a door retaining bar mounted on the door or the body to be pivotable, and including one first side and a profiled section formed on the first side; a first braking element arranged respectively on the other part (door or body), which is applied by sections on the first side of the door retaining bar under the effect of a preload, and which, with the profiled section of the first side, defines retaining positions. The inventive door lock device, which enables the door to be selectively opened via defined retaining positions, in particular by a specific stop, is produced according to the present invention such that an actuating device is associated with the first braking element, and so that the actuating device enables the first braking element to be moved against the preload to be no longer in contact with the first side of the door retaining bar.
