ABSTRACT:
In the combination of headrest stay holder and holder bracket for use with a vehicle seat, an improved arrangement is provided, which comprises a force accessible part defined in the headrest stay holder, a releasable rotation-preventive part defined between the headrest stay holder and holder bracket, and a disengagement guide part defined between the holder and a lower end of the bracket. Normally, under a resistance of the releasable rotation-preventive part, a pair of hook-like end parts of the headrest stay holder are engaged with an engagement end portion of the holder bracket , but a great force of rotation can be accessed and applied via the force accessible part, using a wrench or the like, to that holder, sufficient to overcome the resistance, so as to disengage the two hook-like end parts from the holder bracket lower end via the disengagement guide part. In this way, the headrest stay holder can easily be removed from the holder bracket, without troublesome and dangerous processes.
