Audi Q7 with comfort-enhancing Brose technology

Coburg (April 13, 2006). Innovative door and seat systems from Brose enhance the comfort of every car driver. The system supplier's products are also on the list of features to be found in the Audi Q7. In addition to the window regulators for all four car doors, Brose also supplies power seat adjusters and the lumbar support for the latest SUV from the VW Group.

The Audi Q7 provides drivers with both the comfort of a premium class car and the fun of driving an SUV. Brose seat adjusters, for example, make this possible. One particular highlight is the lumbar support integrated into the backrest. Audi has already used the comfort system developed by Brose in its A4 and A6.

The Brose lumbar feature evenly supports the car occupant's iliac crest and the lower spine, alleviating the pressure on the intervertebral discs, at the same time preventing fatigue and a faulty sitting posture. This means the Q7 pilot has a more relaxed, literally fatigue-free and, subsequently safer ride. Other advantages of the system: compact electrical drive units allow the support of the lumbar area of the back to be adapted with regard to the horizontal and vertical adjustments, thus meeting the indivdual requirements of the car occupants.

Its good acoustic quality on account of the barely audible electro-motors and its low weight are further benefits. The automakers appreciate the quick assembly of the lumbar support whose easy installation in the backframe saves costs.

Brose's 6-way power seat adjuster also enhances the ride comfort in the Audi Q7: the length, height and tilt adjustments of the seat can be easily made at the touch of a button - or optionally by means of the memory function. Different seat positions can be memorized via a seat control-unit and accessed, whenever required. In addition to the "normal seat", Brose also supplies a sports variant: compared to the basic design, this seat provides improved side support on twisty roads and thus increased safety.

The automaker primarily benefits from the use of leading edge developments and manufacturing methods. Lightweight profiles made out of high-strength steel are used for the length adjuster guide rails. Other components are laser-welded. By using this joining technology first implemented by Brose for the industrial large-volume production of seat structures, it is possible to achieve an optimal mix of costs, weight and strength.

Apart from the seat components, the Coburg system supplier also delivers the car's window regulators, the so-called double-guided window regulators which have proved to be successful in previous Audi car models. This window regulator concept is also used for the rear doors. Brose can supply a steel or aluminum version. Due to the weight-saving benefits, aluminum rails are currently used in the Audi Q7.

Costs for the automaker and ultimately the car buyer have also been considered. A new kind of system, for example, has reduced assembly costs with regard to fixing the glass to the window regulator. Instead of being screwed in as previously, the glass is simply clipped into the window regulator with no further assembly effort in the door required, saving valuable time and using fewer parts.

Brose produces the window regulators at its Slovakian plant in Bratislava. They are then deliverd to the final assembly facilities of the Audi Q7, just a few kilometers away. The Coburg system supplier also produces the door systems for the two Q7 sister cars, the VW Touareg and Porsche Cayenne, at the same location.
