NTSEL reviewed seatbelt anchorage and test bench seat cushion dimensions. Comparison test were performed to compare movable and fixed ISOFIX anchorage using two different CRS. Dummy readings with fixed or movable anchorages were almost similar. With fixed anchorages, the removal of the seat from the bench was sometime difficult.
Using seat belt anchorages, this difficulty doesn’t exist. It is suggested for an easier bench construction to keep the belt anchorages fixed.
To easily determine T0, NTSEL suggests repositioning the centre of the CRS 350 mm from the cushion limit.
