Abstract:
A method for forming an armrest of a rotatable type with a rotation means, comprising the steps of:providing an incomplete armrest unit pre-assembled by: a trim cover assembly of three-dimensional configuration formed in a shape conforming to an outer shape of said armrest; and said rotation means which is attached to said trim cover assembly; providing a hinged foaming die means comprising a stationary die and a movable die rotatably connected via a hinge means with said stationary die; providing a core die means to be accommodated between said stationary and movable dies so as to cover and retain said rotation means of the incomplete armrest unit therebetween; providing a location pin adapted to locate and retain said rotation means at a predetermined point in said stationary die; placing said incomplete armrest unit in said stationary die; retaining said rotation means of the incomplete armrest unit at the predetermined point in the stationary die by means of said location pin; setting said core die means on said stationary die so as to cover and support said rotation means of the incomplete armrest unit; causing said movable die to rotate about said hinge means toward said stationary die, thereby closing both said movable and stationary dies; then, injecting a liquid foaming material into the inside of said trim cover assembly; and subjecting said incomplete armrest unit to foaming by curing said liquid foaming material into a foam padding filled in the trim cover assembly, whereby said armrest of a rotatable type with said rotation means is formed.
