  • Patent number: 10407951
    Abstract: The invention relates to a motor vehicle lock, comprising a lock housing, a lock case, a locking mechanism and an operating device, wherein at least one component of the operating device extends through an opening in the lock housing and said opening is designed with at least one reinforcing insert. The main area of the plate or the metal sheet from which the lock case is made is basically relatively large. In light of this, it has proved advantageous to form the reinforcing insert from the lock case. Waste is thus avoided.

  • Patent number: 9551172
    Abstract: The invention relates to a motor vehicle door lock comprising a locking mechanism, at least one locking lever (3) and an electric drive (5, 6, 7) for the locking mechanism. In normal operation, said electric drive (5, 6, 7) acts upon the locking mechanism for an electric opening. Additionally, the electric drive (5, 6, 7) allows the locking mechanism to be mechanically opened at least for an emergency operation. According to the invention, said locking lever (3) remains, in the normal operation, in the ‘locked’ position, also when opened electrically.
