Seatbelt and airbag manufacturer Autoliv has acquired global supplier Delphi’s pyrotechnic safety switch (PSS) assets in Europe.

The deal will see Autoliv acquire assets related to the Delphi PSS business in Europe. The transaction includes intellectual property and physical assets for supplying key customers such as Daimler, Audi and Porsche.

Delphi’s European assets are expectd to book about US$10m in sales this year.

In the event of an accident, the PSS or battery disconnect is activated by the deployment of the airbag. The PSS isolates the battery from the vehicle starter and alternator, which helps prevent short circuits and reduces the likelihood of a resulting fire.

The PSS technology is based on existing airbag technologies.

Applications for electric and hybrid vehicles include crash protection of vehicle wiring circuits and associated battery storage systems, which can be applied in most light models and heavy commercial vehicles.

“This acquisition supplements our efforts to grow in the passive safety market and in particular supports our focus on improving safety in vehicles using not only traditional combustible engines, but alternative fuel technologies such as hybrids or batteries,” said Autoliv president and CEO Jan Carlson.

“With the trend towards smaller vehicles and alternative energies in many light vehicles, the demand for products such as the PSS will likely become more important in the future.”

This transaction is expected to close by 30 April, subject to regulatory approvals and customary closing conditions.
