Bailey crash tests motorhomes to improve safety
Bailey, which entered the motorhome market just two years ago, has made important advances in motorhome safety
Bailey has completed a series of crash tests of its coachbuilt motorhomes aimed at improving passenger safety, especially of those travelling in the rear seats.Through 2011 and 2012, the company carried out five crash tests at the Millbrook Vehicle Proving Ground in Bedfordshire, which simulated a full frontal crash at 30mph.
For the tests, Bailey used a life-like motorhome made from a dummy cab (it had no engine or front seats for most of the tests) with an Al-Ko chassis upon which was built a motorhome structure that included within it both forward and rear-facing seats with three-point seatbelts, a full motorhome kitchen, including oven, hob, microwave and fridge, as well as cupboards, doors, lockers and light fittings.
Four crash tests dummies – both adult and child size – were positioned and secured using the seatbelts into the rear seats of the test motorhome.
The first crash test, which was carried out early 2011, revealed that the rear seat passengers, despite being secured, were subjected to life-threatening conditions after the seats collapsed and both the rear facing passengers were thrown free.

As soon as the first test was complete, Bailey modified its motorhomes.
While it found that throughout the testing, its Alu-Tech bodyshell stood up well, it was found that Al-Ko chassis outriggers were needed to reinforce the floor underneath the rear passenger seats and kitchen area.
These outriggers are now included on all Bailey motorhomes.
During the first test, both the fridge and the oven came free and flew out of the front of the motorhome.
Bailey now anchors ovens and the fridges in all of its motorhomes to the floor.
The furniture also needed significant modification and dedicated storage was made for the table after three of the four rear seat passengers were hit by the flying table after it came loose. The table leg also broke and the table’s rail broke free and flew out of the window. The manufacturer has also now relocated its under-locker lighting after it was found the lights could injure the passengers.

However, it was the motorhome’s bulkhead, which separates the rear passenger seats from the cab, that proved the toughest nut to crack and took a further three tests to get right.
In a motorhome built using Bailey’s Alu-Tech, the bulkhead is already a structural component of the shell, making it much more solid than a standard furniture panel used in some other motorhomes. However, even this required extra strengthening with a steel frame support and a steel brace mounted through the floor before it met the final test targets.
The bulkhead protects the rear-facing passengers and supports their backs. If it gives way, the passenger’s body can twist and he can be thrown free from the seatbelts. Indeed, during the first of the Bailey tests, the rear-facing passenger closest to the aisle ended up in the cab.
Despite its importance in protecting rear passengers, some motorhome manufacturers currently only use a standard furniture panel for the bulkhead.
Following the completion of its crash tests, Bailey has now made its findings and the engineering changes it has made as a result of the crash tests available free and without patent protection to other motorhome manufacturers through the National Caravan Council (NCC). It is hoped that other manufacturers will adapt their own production processes to make their motorhomes safer using Bailey’s findings.
Another British manufacturer, Swift, is also now carrying out similar crash tests on its coachbuilt motorhomes.
