英国婴儿和儿童汽车安全座椅制造上布雷泰克斯公司，自1998年以来开始以Dassault Systemes的CATIA V5来开发座椅系列产品。
该公司工程部经理伊恩.鲍威尔说：“CATIA V5作为一个很优秀的产品数据开发平台，使得我们能够在汽车安全座椅这个行业内不断推出新的产品。”
伊恩继续说： "为了保持不断变化的市场上领先地位，我们不但要考虑父母及照顾者的需求，而且还要考量到那些OEM整车座椅的舒适性。所以工程开发人员必须能够熟练的操作CATIA平台，而且还要理解即将到来的NPACS儿童座椅法规。

“Catia is the perfect data repository for the rule-based regime under which we work because it allows us the creative freedom that we need to innovate while providing the ideal framework within which to operate at optimum efficiency in all departments.”
Testing moments
Britax car seats are highly engineered with European Standard and CREST testing carried out in-house and finite element analysis (FEA) performed by specialist external contractors. The Andover facility is equipped with two deceleration sleds, the larger of which incorporates a decelerator capable of simulating a pulse of up to 80g – well beyond the 20 to 28g pulse corridor legislated at European standards level that equates to a 50kph impact. Further, Britax has the capability to do full body in white testing using this sled, which is also used for the company’s testing work for the aircraft and helicopter seating business.

Iain Powell comments, “We use Catia V5 to retain the information and design parameters that allow us to exceed the brand expectations of our customers. This means that we can design exactly what the market desires, and will buy, while ensuring that throughout the design to manufacture process we always comply with the required engineering and safely constraints.” Shaun Clark, managing director of system supplier, Applied adds, “The business benefits that Britax derives from its five seats of V5 R17 technology lead to accelerated time to market because it is the same software developed for and deployed by the world’s leading aerospace, automotive and innovation enterprises. Catia allows Britax to take full advantage of the benefits of parametric methodology allowing it to iterate and upgrade designs to boost sales, while at the same time, according with and exceeding the stringent safety standard that govern the child seat industry. Applied works with Britax to ensure that its designers and engineers make the best use of V5 technology and are able to take advantage of the most appropriate Catia modules for their needs through training, upgrade implementation and support.”
Rules and tools
One example of this is found in the way that Applied helped Britax integrate phases of its design to manufacture processes using Catia to communicate designs and related data to those in the production chain. Iain explains, “We use 3D to design and validate our products and as this progresses from concept through production to shipping, we communicate the results at each stage, often using rendered images or other representations of the data in the form most appropriate to the recipient.
“Throughout this process test results, fixing techniques, overall design and consumer feedback are validated with results coming back to Catia for iteration. Meanwhile, Bills of Materials (BOM) are automatically updated and NC programme or tool design data modified. The parametric features of Catia allow us to design with maximum efficiency with the application of rule based methodology”
Extended family
The Britax product range is extensive with pushchairs and travel systems covering virtually any need from all terrain travel systems to chic town models that can convert to prams. Britax ensures optimal communication with its expert supply chain using the design and production data generated and maintained within Catia. In this way Britax is able to add brand value, continue to innovate and achieve greater market share together with enhanced customer satisfaction.
Iain Powell concluded, “Catia allows our designers to work faster and more efficiently than with other systems that we have tried because the interface is very intuitive and the system allows us to order our production methodology and practices so that there is no gap between what we design and what we manufacture. This is crucial in a business where safety is so important but customer appeal, utility and brand value also sell products.
“By creating our product ranges digitally in 3D using Catia V5, sharing the vision with those that need to see it and communicating that data from a single system, we have developed the ability to be innovative, flexible, safe, efficient and to maintain our position as the UK’s premier car seat, push chair and travel system brand.”(end)
