Analysis of Modification and Costs for Child Seat Anchorages

摘要

The study examined the impact of proposed child seat tether anchorages on vehicle design, weight and per unit cost. Improved child seat designs being offered by motor vehicle manufacturers to reduce unrestrained child and infant injuries has led to an examination of the adequacy of tether strap anchorages on current vehicle models. The tether strap restrains the top of the child seat from pitching forward and anchorages would be required on all passenger cars, multi-purpose vehicles (vans) and light trucks (under 10,000 lbs. GVWR). The study surveyed selected 1980 passenger cars and light trucks, determined the vehicle modification required, and reestimated weight and cost impact.
