Abstract:
An attachment member for fixing a perforated component having a through hole to a support by means of a fastener having a shank and a head formed at an end of the shank, said attachment member comprising an integral body having a through bore formed therein to define a passage for the shank of the fastener;said body having a first deformable portion, a substantially undeformable central portion, and a second deformable portion arranged in that order along an axial direction of said through bore; said first deformable portion being sized to form a crushable stop for the head of the fastener, when the fastener is forced in the axial direction toward the perforated component and the support, and adapted to be axially compressed between said central portion and the head of the fastener; and said second deformable portion being sized to be insertable in the through hole of the perforated component and adapted to be axially compressed between said central portion and the support when the fastener is forcedly driven in the axial direction, whereby said attachment member functions as a dual impact-absorbing mechanism to prevent the perforated component from cracking as a result of the axial forced movement of the fastener.
