Problems solved by technology
In automated assembly plants, retainers with missing seals cannot be detected and will be installed on unfavorably used articles
Loose retainers of this type rattle or squeak, can provide a path for moisture to penetrate, and do not adequately secure secondary products or items as desired
If the seal is attached to the skirt of the retainer, the seal will not function optimally when the retainer is not seated exactly against the panel
Additionally, the position of the seal relative to the skirt of the retainer limits the range of panel thicknesses over which the retainer can be effectively used to provide a seal against moisture intrusion
[0010] Those skilled in the art will appreciate that the pull-down force provided by the flexible wings is partially misaligned due to the application of a compressive force that results in an upward reaction against the application of the head, so remains in the retainer head. The seal between the head and the support panel can occur in structural stacking conditions

Embodiment Construction
[0020] Referring now more particularly to the drawings, and in particular figure 1 with figure 2 , it can be seen that the present disclosure provides a retainer 10 adapted to secure a molding 12 or other surface element to a sheet metal support panel 14 or other underlying support element made of metal or the like . As shown, in the illustrated exemplary construction, the retainer 10 includes a retainer head 16 and a snap-fit clip portion 18 . It will be appreciated that the retainer head 16 and clip portion 18 may be formed as a unitary monolithic unit by injection molding or other suitable molding or fabrication process. The material used for the retainer 10 can be optimally selected as suitable for its particular installation and use. Accordingly, retainer 10 may be made of a suitable plastic, such as nylon, polypropylene, acetal resin, etc., as are well known to those skilled in the art. In some use environments, acetal resins and nylon 6.6 may be preferred. Of c...

A connection assembly is adapted to connect a surface element (12) to an underlying support structure (14) while maintaining a substantially zero-gap abutment relationship between the surface element (12) and the underlying support structure (14). The connection assembly includes a press-in retainer (10) having a circumferential seal (50) with a sealing foot (54). The sealing foot flexes about a living hinge (56) while maintaining continuous sliding contact with the support panel without interfering with downward movement of the retainer.
Description
[0001] Cross references to related patent applications [0002] This non-provisional application claims the benefit of and priority to US Provisional Application 61 / 739,604, filed December 19, 2012. The contents of this provisional application and all other patent documents mentioned in this provisional application are incorporated by reference in their entirety into this application as if fully set forth herein. technical field [0003] The present disclosure generally relates to retainer-incorporated connection assemblies, which may also be referred to as fasteners. More specifically, the present disclosure pertains to connections incorporating a push-in retainer having a downwardly deflected wing feature that secures the retainer in place after insertion through a hole, and The holder has a seal for creating a barrier against moisture, dust and noise passing through the hole in which the holder is secured. Background technique [0004] Push-on W-base retainers are used...
