Benefits of technology

The present patent describes a single-piece fastener that combines a clip and a sealing member for securely attaching a panel to a frame and forming a seal against the frame. The fastener is designed to accommodate varying thicknesses of the frame and can be used to secure automotive door panels to the doorframe. The sealing member is attached to the clip and includes an axially extending rib that forms a seal around the opening in the frame. The fastener also includes a post that helps limit the deformation of the clip legs when it is being inserted into an opening. The technical effects of this invention include improved sealing and retention, reduced assembly steps, and compatibility with different frame thicknesses.

Problems solved by technology

Additionally, the use of two separate pieces may result in the pieces being separated or lost during the assembly process, requiring rework or resulting in a door panel attached to a doorframe without the desired sealing against the doorframe.
Additionally, the use of differing fasteners may result in the wrong fastener being inadvertently inserted into a portion of the doorframe for which it is not designed.

Embodiment Construction

[0053]The following description is merely exemplary in nature and is not intended to limit the present teachings, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals (e.g., 20, 20′, 20″, etc. and 20, 120, 220, etc.) indicate like or corresponding parts and features.

[0054]Referring to FIGS. 1-8, a single-piece fastener 20 according to the present teachings is shown. Fastener 20 includes a clip 22 and a seal 24 attached thereto. Clip 22 is a relatively hard and rigid piece while seal 24 is a relatively soft and flexible piece. Fastener 20 is operable to retain a panel, such as a door panel 26, to a frame or support member, such as doorframe 28, as shown in FIG. 8. Seal 24 is operable to seal against doorframe 28 to inhibit moisture, liquids, debris, and noise from entering into the interior of the automotive vehicle through doorframe 28.

[0055]Clip 22 includes a generally-circular head 30 and a generally-circular collar 32 with a...

Abstract

A single-piece fastener includes a relatively hard clip and a relatively soft seal. The seal can be overmolded onto the clip. A thermal bond is formed between the seal and the clip to inhibit removal of the seal from the clip. The flexible nature of the umbrella of the clip and the seal can accommodate sealing openings in panels of varying thicknesses.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 841,640, filed on Aug. 31, 2006, and U.S. Provisional Application No. 60 / 919,675, filed on Mar. 23, 2007. The disclosures of the above applications are incorporated herein by reference.FIELD[0002]The present disclosure relates to fastener clips and more particularly to fastener clips with a seal.BACKGROUND AND SUMMARY[0003]The statements in this section merely provide background information related to the present teachings and may not constitute prior art.[0004]Fastener clips can be used to retain two components together. For example, fastener clips can be used to retain an automotive door or trim panel to an automotive doorframe or support surface. The fastener clips can engage with a doghouse assembly in or on the door panel and can be inserted through an opening in the doorframe to retain the panel on the doorframe. To reduce liquid, debris, and noise from enter...
