Opel Meriva

Flexible Allrounder

In the spring of 2003, Adam Opel AG launched the "baby brother" of the Zafira onto the German market the Meriva, which was developed on the basis of the Opel Corsa. Bertrandt’s Rüsselsheim branch was commissioned by the OEM as well as by various system suppliers to develop some aspects of the new minivan.


Insulation and carpets
The company was given the go ahead in the spring of 2001. Based on European requirements with regard to acoustics and ergonomics as well as crash behaviour, Bertrandt developed the engine compartment components and carpets. Special emphasis was placed, for example, on developing the complete insulation package. Among other things, this involved covering specific acoustic weak points with insulating material. It also included a consideration of the manufacturability and assembly of some insulation components.


The on-board electrical system
The wiring layout and the on-board electrical system were designed and installed in cooperation with Delphi. For example, this included the wiring layout around the body, the wiring of the doors and the engine compartment wiring. Since Bertrandt was also responsible for the insulation package, the short communication distances within the company were a major advantage that allowed them to supply high quality on schedule.

The feature box offers new functionalities

Also included in the scope of the project for Bertrandt Rüsselsheim was the development of the double floor in the boot the so-called feature box. The idea of utilising the space between the body and the floor of the luggage compartment set new challenges for the engineers. After all, the empty space also had to provide enough room for the warning triangle, a removable tow bar and the first aid kit, without however impairing access to the spare wheel. At the same time, the closure for the spare wheel had to be easily accessible. For this reason, extensive package investigations were carried out in the run-up to the start of development. Concepts for dividing up the luggage compartment using various manufacturing techniques were developed and implemented based on Opel’s decisions.


The development of the glove box was carried out in cooperation with a system supplier. The company, which is located in Strasbourg, had been commissioned to develop the tools and components for the glove box as well as to manufacture the tools themselves. On behalf of the supplier, Bertrandt took on the complete development work from the initial concept right up to series production readiness. In the concept phase, emphasis was placed above all on meeting the crash and safety requirements. A good deal of creativity was called for in the design of the opening mechanism. For the European version, Opel wanted a special catch that had to pass the Misuse Test: Lid Open.

Bertrandt would like to thank Adam Opel AG, the system suppliers and all partners for their trust that they showed in awarding this contract. The excellent and close cooperation made it possible to complete the project within a very tight schedule. Bertrandt Rüsselsheim was able to provide its customers in this project with a particular benefit due to its interdisciplinary development work in the field of insulation and electrical system development. Internal synergies and short communication distances within the Rüsselsheim facility as well as the Bertrandt Engineering Network ensured that the project ran smoothly. The provision of innovative services in whole vehicle development are a guarantee that Bertrandt will continue to be a competent and reliable partner for its customers.
