Our Crash Test Research Centre
If car engineers use crash tests to ensure maximum safety for their occupants, why not do the same with child seats?
If you have ever wondered how we do it to have the safest car seats on the market, here we explain all our secrets.
A Unique Laboratory
The Jané Crash Test Research Centre was built in 2003 when, as a result of our commitment to child safety, we decided to create our own crash test tunnel where we could test our seats to the limit to achieve a level of safety that goes beyond the legal requirements.
All the Jané seats are created in the JANÉ CRASH TEST RESEARCH CENTER, the only private crash tunnel in Spain for researching child safety.
As it is situated beside our factory in Palau-Solità i Plegamans (Barcelona), we can use the Crash Test facility as much as is necessary (and then some more). And that's how we can offer you the most tested seats on the market with the strictest certification of Europe.
Going Beyond Legal Requirements
Our car seats can be tested up to 250 times before being put on the market.
We stage crashes equivalent to 85 km/h (53 mph) in the car - much higher than the European Safety Regulations of 30 mph or ADAC crash tests at 40 mph.
All of our car seats meet and exceed the ECE R44.04 Safety Standard, and/or the ECE R129 Safety Standard for i-Size versions
Are Jane interchangeable eg can a crosswalk seat go on a trider base?
Johnston Prams Replies:
No, Each pushchair seat unit is designed for their particular chassis. This is so they can fold with the chassis and are also stable, as some chassis and pushchair on the Jane range are higher off the ground than others.
The Jane car seats can go on different jane chassis or pushchair, but not the pushchair seat units.
hope this helps.
