Definitions

• the invention relates to a motor vehicle door lock, with a locking mechanism, and with a closing / opening device with drive, wherein the closing / opening device operates on the locking mechanism.
• Zuzieh- / opening devices for motor vehicle door locks have been used mainly in high-priced cars.
• a particularly convenient approach is achieved because an operator only has to spend the associated door or flap in the pre-locking position and then ensures the closing device for the complete closing operation.
• opening aids that ensure that an associated locking the motor vehicle door lock is opened by a motor.
• An example of such an opening aid is described in DE 10 2004 052 599 A1.
• the primary aim is to achieve greater comfort.
• the known Zuzieh- / opening devices usually attack directly on the locking mechanism, which in turn is generally stored in a lock case of the motor vehicle door lock. Since the lock case is regularly bolted directly to an associated motor vehicle door, any noise from the drive of the closing / opening device on the motor vehicle door is usually transmitted by structure-borne noise. Since such a motor vehicle door regularly has more or less large cavities, There is a risk that the above-mentioned noises are amplified by any resonances. This is disadvantageous in that one usually wants to achieve increased ease of use with the closing / opening devices. However, if this ease of use is associated with an additional or disturbing noise level, this is classified by potential customers despite the achieved ease of operation as a total negative. This is where the invention starts.
• the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that, with constant ease of use, an improvement in acoustics is achieved at the same time.
• the closing / opening device has an intermediate (acoustic) attenuator.
• this damping element within the closing / opening device first of all ensures that an acoustic decoupling usually takes place between a mandatory motor of the closing / opening device and the other components. It has proved to be favorable when the attenuator is made predominantly of an elastomer or contains at least one such elastomeric plastic for acoustic decoupling.
• the said attenuator or the elastomer used at this point is or is designed so that in particular generated by the already mentioned engine respectively electric motor frequencies are effectively suppressed.
• said motor operates at 3000 revolutions per minute, this corresponds to a frequency of 50 Hz, which in the example case is particularly significant to dampen is. That is, the elastomer must be selected and designed so that, in particular, frequencies generated by the engine are effectively damped.
• other interpretations are conceivable.
• the design is such that the attenuator transmits rotational movements of the said motor of the drive to a downstream actuator.
• the transmission of rotational movements with the help of the attenuator can be done directly or indirectly.

• the attenuator generally connects two components of the output train of the engine together.
• Coupling elements together of which at least one is made of an elastomer.

• the attenuator is designed as a drive belt.
• the actuator is preferably around a linear actuator.
• the drive is composed at least of the already mentioned motor or electric motor and the actuator or the linear actuator.
• a particularly compact and functional embodiment is characterized in that the motor and the actuator are arranged at an angle, in particular at right angles, to one another.
• the output train of the engine or its output shaft usually has a non-rotatably connected worm, which in turn meshes with a worm wheel, which drives the actuator or linear actuator.
• a non-rotatably connected worm which in turn meshes with a worm wheel, which drives the actuator or linear actuator.
• the actuator or linear actuator is generally composed of a spindle and a spindle element. By rotating the spindle can be achieved that the spindle element located thereon is moved back and forth in the linear direction depending on the direction of rotation. This linear movement of the spindle element is now used for the closing / opening movement, as will be explained in more detail in the context of the description of the figures.
