U-base fastener with folded barb and multiple spring arms

A resilient U-base fastener for coupling a first component having a rib to a second component having an aperture therethrough, the resilient U-base fastener comprising:

• a U-shaped body defining a rib receiving cavity between a first side and a second side, the first side connected to the second side at an insertion end, the central rib receiving cavity being designed to receive the rib;
• a first rib retention barb connected to the first side of the body and bending inwardly into the central rib receiving cavity and toward the insertion end, the first rib retention barb being positioned and designed to retain the rib within the central rib receiving cavity;
• a first aperture retention spring arm connected to the first side of the body and bending outwardly away from the central rib receiving cavity and away from the insertion end, the first aperture retention spring arm being positioned and designed to engage a periphery of the aperture to retain the resilient U-base fastener within the aperture;
• a second aperture retention spring arm connected to the first side of the body adjacent the first aperture retention spring arm, the second aperture retention spring arm bending outwardly away from the central rib receiving cavity and away from the insertion end, the second aperture retention spring arm being positioned and designed to engage the periphery of the aperture to retain the resilient U-base fastener within the aperture;
• and
• wherein an inner lateral edge of the first aperture retention spring arm and an inner lateral edge of the second aperture retention spring arm define opposite sides of a gap in the first side that continuously extends from respective free distal ends of the first and second aperture retention spring arms toward the insertion end to separate the first aperture retention spring arm from the second aperture retention spring arm from one another, and the inner lateral edge of the first aperture retention spring arm has an inner vertical height that is longer than an outer vertical height of an outer lateral edge of the first aperture retention spring arm.

• a U-shaped body defining a central rib receiving cavity between a first side and a second side, the first side connected to the second side at an insertion end;
• the first side of the body including a first aperture retention spring arm and a second aperture retention spring arm that each bends outwardly away from the central rib receiving cavity, the first and second aperture retention spring arms being positioned and designed to engage a periphery of the aperture to retain the resilient U-base fastener within the aperture;
• the first side of the body including a first rib retention barb and a second rib retention barb that each bends inwardly into the central rib receiving cavity and toward the insertion end, the first and second rib retention barbs being positioned and designed to retain the rib within the central rib receiving cavity;
• the second side of the body including a third aperture retention spring arm and a fourth aperture retention spring arm that each bends outwardly away from the central rib receiving cavity, the third and fourth aperture retention spring arms being positioned and designed to engage the periphery of the aperture to retain the resilient U-base fastener within the aperture;
• and
• wherein an inner lateral edge of the first aperture retention spring arm and an inner lateral edge of the second aperture retention spring arm define opposite sides of a first gap in the first side that continuously extends from respective free distal ends of the first and second aperture retention spring arms toward the insertion end to separate the first aperture retention spring arm from the second aperture retention spring arm, and wherein an inner lateral edge of the third aperture retention spring arm and an inner lateral edge of the fourth aperture retention spring arm define opposite sides of a second gap that continuously extends from respective free distal ends of the third and fourth aperture retention spring arms toward the insertion end to separate the third aperture retention spring arm from the fourth aperture retention spring arm.
