I wonder where does the 136x53 size come from... It must be some everyday object the testers used as the source of a reference point.... An offcut of some timber, a box of their favourite biscuits, or something.
Measuring from the base of the seat it seems I can acheive a height greater than 45cm including the 53mm but is it Ok for the harness to anchorage point to be lower than your shoulder...
I could possibly make a spacer from solid round bar and move the anchorage point higher if needed but would this be neccessary if above 45cm as stated??
