I haven't seen anything on this particular issue and most of the research I am aware of is on seat belt use or non use and its effects in a collision. I did a paper some time ago when we had a similar issue in a particular type of LGV not directly related I know but principles are the same. But from memory there were so many variables that it could not be put down to one particular cause age and sex being just a couple of the issues. I will come back to you.....:)

We operate a number of these vans and as far as I know without any complaints, will check though and if any issues will come back to you.

have you got someone who can do an ergonomics assessment along the lines of a DSE assessment only for vehicles. Phil

Found my presentations... Back pain is common amongst drivers and there are several reasons for this: driving forces prolonged sitting in a fixed posture; transference of vibration and loss of spine support due to a poorly fitting seat. Recommendations (in addition to those for general seating): •Good visibility of the road should be possible, together with a good view of all the instruments. •The driver should be able to reach all of the controls (pedals and hand controls) without stretching. •The body should be supported and muscular effort minimised to allowing the driver to concentrate on the driving task. •Shaping and padding should allow good distribution of body weight over the seat. •Vibration and shock transfer should be minimised. In order to minimise discomfort, the driver's seat should also offer as many adjustable features as possible. The most important ones are: •Backwards and forwards adjustment of the seat, •Backrest angle adjustment, •Seat height adjustment – ideally independently adjustable at the front and rear of the seat, •Seat angle adjustment, •Adjustable lumbar (lower back) support - up/down and in/out, •Headrest adjustment - vertical, horizontal and tilt. The more adjustable features within the car (e.g. steering wheel adjustment in/out, up/down and tilt), the greater the likelihood of the driver achieving good and comfortable postures. But any posture, no matter how good it is, can lead to discomfort if it is held for too long. Therefore, it is important to adopt a range of comfortable driving positions and to make frequent stops to avoid, or help delay, the onset of discomfort. Ease of use of any adjustable feature is therefore crucial.
