Double guided cable window regulator from Brose for the BMW 7series
Power window regulators from Brose
As the worldwide technological and market leader with more than 70 years of
experience, we equip every fifth vehicle worldwide with our window regulator
Brose was the first manufacturer to supply power controlled units for window
regulators in series production. This window regulator electronic system
provides additional convenience as well as protecting passengers against
sustaining severe injuries if, for example, fingers get caught in the closing
window. Trend-setting innovations in mechanics, electrics and electronics have
shaped our success.
Brose has over 70 years' experience in the window regulator business. In the
twenties, the automotive supplier produced window crank equipment which even at
that time was very future-oriented. Furthermore, the company's founder, Max
Brose, purchased the patent for "wrap sling brake" from the Detroit company,
Ternstedt, which was later to become General Motors. The wrap spring brake make
in possible to hold a car window in an open position. The folding-side window
was a thing of the past. At that time, competitors were only able to supply a
As there was an ever-increasing demand for the wrap spring brake, Brose soon
held the leading market position in window regulators, the brand name of which

Coburg/Germany. From the many years of experience and close
cooperation with Brose, BMW is once again with its 7 series model pinning high
hopes on the automotive supplier’s efficiency. Brose’s power window regulators
contribute greatly to the comfort provided in the new BMW luxury segment.

BMW 7 series (E65/E66)
With the new window regulators, integrating technical developments made since
the predecessor model in the previous 7 series, Brose is continuing the
development BMW wishes to pursue toward a light-weight construction. By using
aluminum, Brose has succeeded in reducing weight substantially: despite an
increase in technical comfort and detail, the complete window regulator set in
the front and rear doors generates extraordinary savings in weight of about 2.5
kg per vehicle.
Like in the previous model, the Brose power window regulator is located
between the door outer panel and glass, thus maximizing the space in the door.
The door trim, for example, provides enough space for large storage pockets,
loudspeakers and soundboxes.
Double guided cable window regulators are to be found in the front doors. In
the rear area, there are single guided variants. An additional compression
spring integrated into the window regulator ensures additional safety. It
optimizes the reaction time of the window regulator electronics and provides
indirect anti-trap protection, thus meeting all international legal requirements.

The second special feature of the new Brose window regulator in BMW 7 series is
the semi-conductor bridge integrated into the window regulator motor. It
improves the comfort of the window regulator by generating a non-jarring noise
when active as well as reducing noise at the bottom limit stop. It also ensures
there are no harsh starts or stops.
