초록

The rear center-hinge bracket is designed for supporting and folding the rear-seat backrest. This bracketneeds to be strong enough to be able to rigidly hold the rear-seat backrest and to withstand luggage loads from the cartrunk that are generated when a vehicle is driving on the roads. Particularly, current accident studies report that manyserious occupant injuries occurred when the rear-seat back easily folded inward toward the car interior, driven by theluggage loads in the trunk. Given this fact, the robust design of the rear center-hinge bracket that mainly supports therear backrest has become more important for providing customer safety and preventing high warranty and durabilityproblems. However, none of the studies have emphasized its significant role and considered its robust optimization.
Therefore, this paper presents how the hinge-bracket design is optimized based on an application of the finite-elementmethod coupled with the parameter design using Taguchi’s design experiment. Finally, Taguchi method’s applicationoptimizes a robust center-hinge bracket that shows more rigid performance although it has lighter weight and thinnerthickness.
