Abstract

The object of the invention is the mechanical unlocking, for example, of door locks on motor vehicles following the end of an accident. For this purpose, the necessary mechanical energy is obtained by means of the release of a pre-tensioned spring. Release is carried out as a result of severing a fusible point by means of a short electrical fusing current surge, which is taken from an electrical store. Vibration sensor, retriggerable switching electronics, store and reverse flow diode can be assigned individually to each fusing point and thus to each door lock, since these parts are of small construction and are cheap. As a result, in the case of failure of the on-board power supply, caused by an accident, each door lock can be unlocked independently of the others. This is only possible since only very short-term low electrical energy is needed for the fusion process, while the energy released in the pre-tensioned spring effects the mechanical unlocking actuation.

Description

Known

For unlocking vehicle doors in particular In the event of an accident, there are several procedures and orders have become known to those usually have considerable disadvantages. The The main disadvantages are premature unlocking still during the course of movement, failure of the Unlocking due to electrical system failure and unfounded Unlocked by shocks that are not by Accident.

Invention idea

The release must be done individually and with each door system assigned to each door without the failure of the electrical system on board the Ent locking process can interfere. The release must not already be during the accident-related movement process, but only after the final rest position.

To this end, the invention names the following components and functions:

The mechanical unlocking must be done by means which due to their simplicity, the minimum of sturgeon vulnerability from both time-related influences, such as corrosion, such as for accident reasons realize. For this purpose, a mechanical Tension the spring so that the stored in it Performance is sufficient, any type Release latch when locking the cocked Spring is released electrically. The easiest The intended effect of the release is by means of a Target melting point provided. The spring is in the tense position held by a melting point, which is designed so that the short-term strong discharge current of an electrical storage the melting and thus simply the release causes. As electrical storage is - depending on  Expense framework and desired lifespan - a chemical condenser, a non-chemical condenser sator or a rechargeable array of cells known type provided. Because of optimal constancy an MP capacitor is preferable.

For the electrical release of the spring is also the Application of an actuating by the discharge current surge Pawl provided. However, there are several defects not adhering to the target melting point swell inevitable, for example clamps, Corrosion, sticking, bending.

Since the release must not take place prematurely, an electrical arrangement is provided, the first by a few seconds after the end of the accident Movement sequence provides the unlock signal. This is a so-called retriggerable electri cal arrangement provided that causes for example several within the intended Delay time of successive impacts each cause the delay time to restart and thus the release of the unlock signal as long prevent until there is no further impact is. This ensures that not during of the course of the accident, he likes it for a long time can be unlocked. The electric one Storage supplies the operating current for this electrical arrangement. So that's it Independence from electrical system failure.

The summary of the described components also with one sensor each in a closed assembly is intended because of the high level of functional reliability. Each with such a compact assembly Unlocking secured door works like this regardless of possible system destruction on others Door or central location.  

The components named for the invention are in State of the art so well known that a detailed illustration for the relevant educated Expert is not required. Since already one A large number of so-called crash sensors are known their principles of spatially small piezoceramic element to simple ball contact, the sensor is not the subject of the invention.

With the multitude of known locking systems the invention only covers the provision the mechanical energy for unlocking in the simple and fail-safe design.

Because it can be cheap for several reasons Storage capacitor with a higher than the board charging the mains voltage is the application of electronic voltage doubling as well Integration of the same is provided in the assembly. This is - especially with regard to EMC - electromagnetic compatibility - as a requirement significant.

Claims (6)

The method and arrangement according to claim 1 further characterized in that an electrical Memory, a capacitor or a rechargeable Cell, via a reflux diode from the vehicle electrical system is charged that the stored electrical Energy the electrical system and the delay feeds and the melting of the target melting point causes, and that this stored electrical Safe energy even if the on-board electrical system fails dimensioned sufficiently.
3. Method and arrangement according to the preceding claims, further characterized in that the performance the mechanically preloaded spring from the short-term Discharge current surge of the electrical storage means released an electromagnetically operated jack becomes.
4. Method and arrangement according to the preceding claims, further characterized in that preferred as the unlocking of motor vehicle doors in Damage trap is executed.  
5. The method and arrangement according to the preceding claims, further characterized in that voltage doublers are provided, the electrical Store on a higher voltage than the board charge mains voltage and that the electrical and electronic components with this higher Voltage operated.
6. The method and arrangement according to the preceding claims, further characterized in that the target melting point is formed by a wire, the one hand on the tensioned spring and on the other hand attached to an insulated clamp is, and if necessary from a reserve role after a random melting and unlocking is tightened and jammed.
