US Patent 11643852 Motor-vehicle door lock

A motor vehicle door lock, more particularly a flap lock or a hood lock includes a locking mechanism substantially consisting of a rotary latch and a pawl. There is also a motorized closing aid which has a motor and also a first lever, which is acted upon by the motor, and a second lever. The two levers are hinged to each other. During the lowering of a flap or hood, the second lever first of all carries out a movement, which is controlled by the rotary latch, while simultaneously freewheeling in relation to the first lever. Only following the freewheeling does the first lever, which is then driven, act upon the second lever, in order to close the rotary latch.
