Megabusa restoration: Seats crotch and Hans

I have been considering a safety upgrade to the Megabusa. I decided to invest in a set of seats that were more substantial than the GRP shells fitted and fit an additional crotch strap to the seat belts and Hans device for my neck.

If you want to know what a Hans device is then there is a very good explanation on Wiki (*).

The crotch strap is a simple addition to the existing Willans seat belts. It stops you sliding under the harness in extreme conditions.

The seats were ordered while at Stonleigh and are made by a company called Intatrim (*) and the product is called Endeavour. Although still a GRP seat it is a much more substantial product than the basic shell seats and they have thought about the crotch strap void in the design.

Hans adapter

A Hans device was purchased from JJC earlier in the year at significant cost. However I was never able to use it in the Westfield as the seat belt straps need to be precisely aligned with the seat apertures and the Hans device. This requires the attachment points in the Westfield to be radically altered. After some discussions with various scrutinisers at the track and after even more thought I designed and fabricated a Hans adapter using the existing Westfield seat belt attachment points. You can see not only have the attachments been aligned horizontally with the Hans device but a 50mm elevation to the attachment has been applied because of the Hans thickness resting on your shoulders.

The adapter was fabricated out of 4mm sheet steel and bright steel studs taped and welded in place on both sides of the plate.

I propose to submit this for scrutinising soon at Kames.
