Embodiment Construction

[0033] The drawing shows a motor vehicle door lock, which is equipped in a conventional manner with a locking mechanism (not shown), which essentially consists of a rotary latch and a pawl. In practice, the locking mechanism is usually perpendicular to figure 1 The lock housing 1 of the motor vehicle door lock shown is extended. To actuate the locking mechanism, a trigger lever 2 is provided, which lifts the pawl away from the rotary catch and is in the unsecured position when the locking mechanism is closed, so that the rotary catch can be opened by means of spring force. This is a common function for opening locking mechanisms as well as motor vehicle door locks.

[0034] Of particular importance to the invention is that a safety element 3 is also provided and acts on a safety bar 4 which will be described in more detail below. The safety element 3 is a transmission rod 3 which can move substantially linearly. The linear motion of the transmission rod 3 is figure 1 is sh...

Abstract

The invention relates to a motor vehicle door lock provided with a locking mechanism. The locking mechanism basically comprises a rotating lock fork and a lock claw, and a safety element (3) is provided. In addition, driving units (5, 6 and 7) are provided for the safety element (3), the safety element (3) is moved through the driving units to at least a safe position and an unsafe position, and the safety element (3) is maintained at the two stable positions with the aid of an elastic element (15). According to the motor vehicle door lock provided with the locking mechanism, the elastic element (15) is constructed to be a part of an actuating hole (10) of the safety element (3) and allows relative movement of the driving units (5, 6 and 7).

Description

technical field [0001] The invention relates to a motor vehicle door lock with a locking mechanism consisting essentially of a rotary fork and a pawl, with at least one safety element and a drive unit for the safety element, which moves the safety element into at least one A secured position and an unsecured position, wherein the securing element is held in both of the stable positions by means of the elastic element. Background technique [0002] There are many known designs of motor vehicle door locks with at least one security element. For example, the security element can generally be a locking element or also an intermediate locking element, as described in the prior art according to DE 195 30 726 A1 and US 5 802 894A. In this case, the drive unit is in the form of a locking drive unit or a central locking drive unit. In addition, however, the security element can also be in the form of an anti-theft system or an anti-theft element. At this time, the drive unit is an...
