Spezo GmbH - Car privacy curtains - Electric drives for curtains

Curtains, as many other car interior components, became the application object of the technical progress aimed to increase the comfort of use. Why should you try and reach the curtains on the rear window from the front seat manually when you can entrust this simple yet tiresome work to an electric drive.

The main advantages of the car privacy curtains equipped with electric drives:

comfort and ease of operating: you just press the button or use the remote control.
operating safety: electric drive control system can terminate the curtains movement immediately in case if any obstacles occur.
a considerable component of one’s image: it’s always nice to impress on the people around you.

The SPEZO company gives a lot of consideration to the designing and manufacturing of the curtain sets with electric drives for the stock cars. The main area of our activities is designing of off-the-shelf solutions for the best selling sedans, business-class minibuses, and also jeeps.

Curtains with electric drives are usually assembled in following ways:

Sedans: rear passenger doors, rear window;
Jeeps: rear passenger doors, rear door;
Minibuses: sliding doors, rear windows, rear door.

Usually the operation of electric drives in the SPEZO curtains sets is implemented by the standard car controls – control buttons of a window raiser or a sunroof. Besides the manufacturing of the car privacy curtains sets with electric drives for the stock cars the SPEZO company designs and manufactures custom-made sets. In this sector electric drives for curtains on saloon dividing partitions are in high demand.

Main advantages of the SPEZO electric drives:

Modular design: the possibility to assemble an electric drive of any shape using a number of reducing modular units.
Quality: we manufacture our electric drives using BOSCH (Germany) car washdown and dustproof electric motors.
Safety: the SPEZO electric drives have successfully passed the endurance tests – 10000 cycles of open-close at the temperatures varying from -30 up to +40 Centigrade. And this fact corresponds to 5 years of day-to-day operation.
Unique design: we have succeeded in producing a totally unique design. At present we are working on patenting it.

The SPEZO electric drives can be classified by the following factors:

a number of reducing modules; a number of driving cables; velocity properties

Electric drives are divided into two types according to design:

standard; compact

The design distinction is in that a body of compact electric drives is located parallel to the driving cables. Due to this fact in many cases the compact electric drives are more easily installed in the door lining\paneling or into the luggage rack lining. The SPEZO electric drives can consist of one or two reducing modules. Therefore, the dimensions of the drives also vary according to the number of reducing modules.

The SPEZO electric drives can be produced with a different number of driving cables (a driving cable is a part of mechanism which actuates the curtain):

1 driving cable;
2 driving cables;
4 driving cables.

The number of driving cables depends on the purpose of an electric drive. Electric drives with 2 and 4 driving cables can be of two types:

One-speed: linear speed of travel of all driving cables is equal. This way upper and lower parts of a curtain travel at an equal speed.
Two-speed: in this case one half of the driving cables travel at one speed and the rest travel at a rather lower speed. This way one part of a curtain travels a bit slower than the other (usually the upper part travels slower).

We have composed a small table for you to get a better understanding of all SPEZO curtains electric drives:

Electric drives with a standard design:

One reducing module, one driving cable, one-speed

Low price due to minimum number of parts.

Easy installation.

The shifting of the curtains is carried out through only the lower part of the fabric (sometimes it is done through the upper part of the fabric).

As a result of this there arises a chance that the curtain will shift unevenly, i.e. the upper part of the fabric falls behind the lower part a bit. This way there is a chance of sunlight appearing between the curtain and the window opening frame.

Electric drives of such type are generally used when installing the automatically driven curtains on side doors in the case if the door frame design doesn’t let you lay the driving cable to the upper part of the curtain.

With one reducing module, with two driving cables, one-speed

	The shifting of the curtain is carried out through the upper and lower parts of the fabric simultaneously. Low price – only one reducing module is used.
	Long driving cables. As a result you need to carefully lay the cables (without the twisting).
	Electric drives of such type are generally used when installing the automatically driven curtains on side doors and side windows if there is a place for laying the ‘long cables’.

With two reducing modules, with two driving cables, one-speed.

The shifting of the curtain is carried out through the lower and upper part simultaneously. As a result it is easier to lay the driving cables.

The price goes up as the two reducing modules are used. The overall thickness increases as the two reducing modules are used.

Electric drives of such type are generally used when installing the automatically driven curtains on side doors and side windows.

Electric drives of such type can also be used for installing the automatically driven curtains on saloon dividing partitions and rear windows in case if, due to design, it is not possible to use one electric drive with four driving cables. In this case you have to use two electric drives for one window or the dividing partition.

With two reducing modules, with two driving cables, two-speed.

The possibility to shift the upper and lower parts of the curtain at different speeds.

The shifting of the curtain is carried out through the lower and upper part simultaneously.

Electric drives of such type are generally used when installing the automatically driven curtains on side doors and side windows in case if you want the upper part of the curtain to travel slower than the lower one.

With two reducing modules, with four driving cables, one-speed

	The shifting of the curtain is carried out through the lower and upper part simultaneously. Low price due to the use of only one reduction gear for one window.
	Electric drives of such type are generally used when installing the automatically driven curtains on the saloon dividing partitions, rear windows and doors.

With two reducing modules, with four driving cables, two-speed

	It is possible to shift the upper and lower part of the curtain at different speeds. The shifting of the curtain is carried out simultaneously by the upper and lower parts. Low price due to the use of only one reduction gear for one window.
	Electric drives of such type are generally used when installing the automatically driven curtains on the saloon dividing partitions, rear windows and doors in case if you need to move the upper part of the curtain at a slower speed than the lower one.

Electric drives with a compact design:

With one reducing module, with one driving cable, one-speed:

Low price due to the use of the minimum number parts.

Easy installation.

The possibility to install in places with a limited capacity.

The shifting of the curtain is carried out only through the lower part (sometimes through the upper). As a result of this there arises a chance that the curtain will shift unevenly, i.e. the upper part of the fabric falls behind the lower part a bit. This way there is a chance of sunlight appearing between the curtain and the window opening frame.

The electric drives of such type are generally used when installing the automatically driven curtains on the side doors in case if the door frame design doesn’t let you lay the driving cable to the upper part of the curtain. Such electric drives, compared to the ones of type 1, are easier installed under the door paneling or the luggage rack fabric.

With two reducing modules, with two driving cables, one-speed

The shifting of the curtain is carried out simultaneously by the lower and upper part.

You can install it in the places of limited capacity.

The price goes up due to the use of two reducing modules. Overall thickness increases due to the use of two reducing modules.

Electric drives of this type are generally used to install the automatic driven curtains on the side doors and side windows. Electric drives of this type, compared to the ones of type 3, are better installed under the door paneling or the luggage rack fabric.

Electric drives of type 8 can be used to install the automatically driven curtains at the saloon dividing partitions, rear windows and doors if due to the design it’s impossible to use one electric drive with four driving cables. In this case you will have to use two electric drives for one window or dividing partition.

With two reducing modules, with two driving cables, two-speed

The possibility to move the upper and lower parts of the curtain with different speeds.

The shifting of the curtain is carried out by the lower and upper parts simultaneously.

The possibility of installation in the places of limited capacity.

Electric drives of such type are usually used when installing the automatically driven curtains on the side doors and rear windows in case if you want the travel of the upper part of the curtain to be slower than that of the lower one.

Electric drives of this type, compared to the ones of type 4, are better installed under the door paneling or the luggage rack fabric.

Electric drives of type 9 can be used to install the automatically driven curtains at the saloon dividing partitions, rear windows and doors if due to the design it’s impossible to use one electric drive with four driving cables. However, in this case you will have to use two electric drives for one window or dividing partition.
