Abstract
Trunk lid stopper mechanism and method for controlling rotational speed of a trunk lid to slow down and halt its movement, and to hold the trunk lid at the halted position. The stopper mechanism comprises hinge arms for supporting the lid, torsion bars for applying biasing force to the lid, and link arms for transmitting biasing force from torsion bars to the hinge arms. Either each hinge arm or link arm is equipped with a stopper member that brakes the rotation movement of the trunk lid and halts the trunk lid fully-open. The stopper member has tapered surfaces for reducing relative rotational speed between the hinge and link arms by being forced therebetween during their relative rotational movement, and a stopper surface(s) for abutting against the other arm and halting the arms' relative rotational movement at the fully open position of the trunk lid.
