Welding arrangement for plastic components

A welding arrangement for plastic components, comprising:

• a base member comprising a base body at least partly made of thermoplastic material;
• a primary attachment member abutting onto the base member, the primary attachment member being provided with a first positioning feature that engages a corresponding first positioning feature provided on the base member, and
• a secondary attachment member at least partly made of thermoplastic material and vibration welded to the base member so as to at least partly interpose the primary attachment member between the secondary attachment member and base member, and so as to couple the primary attachment member, via being attached to the secondary attachment member, to the base member;
• wherein the first positioning feature of said primary attachment member comprises:
• a pair of spaced-apart engagement portions extending outwardly proximate respective lateral end portions of the primary attachment member, said engagement portions being substantially parallel to one another;
• and
• a lateral projection extending laterally outwardly on each of said respective lateral end portions of the primary attachment member, said lateral projections being substantially opposed to one another;
• wherein the first positioning feature of said base member comprises a pair of spaced-apart openings formed in the base body and configured to respectively receive said engagement portions therein;
• and a pair of spaced-apart openings formed in the base body facing toward one another, and configured to respectively receive said lateral projections therein;
• and
• wherein the primary attachment member engages the secondary attachment member so as to permit sliding positional adjustment therebetween in a prescribed direction corresponding to a direction of movement of the vibration welding.
