The invention relates to a motor vehicle door lock which is equipped with a locking mechanism (1, 2) consisting of essentially a rotary latch (1) and a pawl (2), in addition to an actuating lever chain (4) and a locking unit (5, 6). Said motor vehicle door lock also comprises a security device (8, 9, 10) which can optionally set the actuating lever chain (4) and/or the locking unit (5, 6) in a non-functioning state/functioning state. According to the invention, said security device (8, 9, 10) is designed as a retrofitted module (8, 9, 10) which can be connected, according to requirements, to a base module (1-6 and 11), said module surrounding the largest part of the locking mechanism (1, 2), the actuating lever chain (4) and the locking unit (5, 6).
Motor vehicle door lock which is equipped with a locking mechanism (1, 2) consisting of essentially a rotary latch (1) and pawl (2) in addition to an actuating lever chain (4) and a locking unit (5, 6) as well as an optional security device (8, 9, 10) selectively setting the actuating lever chain (4) and/or the locking unit (5, 6) in a non-functioning/functioning state, characterized in that the security device (8, 9, 10) is designed as a retrofitted module (8, 9, 10) which can be connected according to requirements to a base module (1 to 6 and 11), said module surrounding the largest part of the locking mechanism (1, 2), the actuating lever chain (4) and the locking unit (5, 6).
Method for selectively operating a motor vehicle door lock with or without security device (8, 9, 10), in which a base module (1 to 6 und 11) contains at least one locking mechanism (1, 2) essentially compromising a rotary latch (1) and pawl (2), an actuating lever chain (4) and a locking unit (5, 6), and in which the security unit (8, 9, 10) selectively setting the actuating lever chain (4) and/or the locking unit (5, 6) in a non-functioning state/functioning state, is a retrofitted module (8, 9, 10) connected to the base module (1 to 6 und 11) where required.
Motor vehicle door lock according to 7, characterized in that the centering elements (12, 13, 14) are formed on the respective module housing (10, 11) and/or on built-in elements (12) in or on the module housing (10, 11).
