In a further embodiment, the component is designed to be moved by a delay of at least 10 · g by its self-inertia, where g = 9.81 m / s ^{2 is} the gravitational constant. Such delays occur in severe head-on collisions, with delays of less than 10 · g usually do not bring such serious vehicle damage that an additional mechanical unlocking in the sense of the present invention seems necessary, especially in these deceleration values encountered in normal driving behavior unlocking by the component undesirable and unnecessary.

In a further embodiment are the unlocking mechanism and the component via a connecting means interconnected and are the mass of the component and the mass of the connecting means chosen such that the component at a Frontal impact of the motor vehicle by the inertia relative to the vehicle door is moved.

For the success the mechanical unlocking, it is important that the component mass inertia is moved and the unlocking mechanism is activated, for. B. on pull or push him. In the embodiment the last paragraph will be added considered, that also the connecting means, for. As a rope, between the component and the unlocking mechanism has an inertial mass and in the case of corresponding delay can contribute to unlocking.

These it is the connecting means, for example, a rod, the as well as the component absolutely in the vehicle longitudinal direction and relative to associated Motor vehicle door is movable, so the unit may be component / rod or general the unit component / connecting means is a component in the sense of the first embodiment represent.

According to one another embodiment is a rope between the unlocking mechanism and the component or a rod provided.

In a further embodiment It is suggested that the door lock on a vertically movable rod is unlocked, and that transfer means to transfer a in the vehicle longitudinal direction taking place component movement in a vertical movement of the rod available.

A such embodiment allows the use of the invention in such vehicles in which the Unlocking mechanism one end with a release button provided unlocking bar, the unlocking vertically after must be moved above. In such vehicle models is thus the force necessary for unlocking force direction perpendicular to the vehicle longitudinal direction. The transfer means ensure, that takes place at least in the vehicle longitudinal direction component movement is converted into a movement of the rod vertically upwards.

The transfer agent can be a pulley for a rope between the unlocking mechanism and the Component is stretched. The rope can then z. B. via an eye with the lower end of be connected to the above-mentioned rod.

In an alternative embodiment is instead of the pulley as a transfer agent on the rod fixed carrier selected, the one with a slope is assigned equipped component.

at this embodiment moves in a frontal impact, z. B. a in the vehicle longitudinal direction movable and, for example, movable component, eg. B. in shape a carriage, towards the front of the vehicle. The slope runs here to the rear part of the vehicle upwards, so that the driver the slope led upwards becomes. At the end of the component movement or at the end of the frontal impact For example, a locking secures the unlocking, so afterwards the driver does not just slide down the slope and that Locks is locked again. The unlocking mechanism can therefore in principle be used several times.

A another embodiment provides that as a slope a structurally easily realizable ramp is provided on the the driver slides in a frontal impact upwards.

A another embodiment Provides that the door lock can be unlocked by a vertically movable rod, on the rod a driver is provided, the component to a vehicle transverse direction lying axis is rotatably mounted and this has an area which raises the driver from below when turning the component. at this embodiment will not be a separate means of transfer needed with which a component movement is converted into a vertical movement of the (unlocking) rod. Location and shape are chosen so that the component with his Area B pushes from below against the driver and thereby lifts him. The area B can be chosen as edge or groove, which when swinging takes the driver with him.

Further sees an embodiment before that the component is integrated in the lock, z. B. as a pivoting Part. This construction is very compact and leads to reduced assembly time in vehicle production.

One second aspect of the invention relates to a motor vehicle with a vehicle door according to one of the previous embodiments.
