Plastic J-hook retainer with rubber
View Patent ↗A J-hook retainer includes a rigid structural component shaped with a hooked end. A soft rubber section is applied to or molded with the rigid structural component. The J-hook retainer holds a trim fabric in place over a vehicle component frame. Advantageously, the soft rubber section minimizes free play and rattling as well as assisting in avoiding sliding and detachment in case of partial contact between the J-hook retainer and vehicle component frame.
1. A J-hook retainer for attaching interior trim to a vehicle component, the J-hook retainer comprising:
a rigid structural component shaped with a hooked end, the hooked end defining a curved section for receiving a vehicle structural component, the rigid structural component including a shank side and a bite side with a protrusion extending from the shank side, the protrusion being a retainer feature that holds the J-hook retainer to a retainer component that is integrated with the vehicle structural component; and
a soft rubber section is disposed over a portion of the rigid structural component.
2. The J-hook retainer of claim 1 wherein the rubber section is molded to the rigid structural component.
3. The J-hook retainer of claim 1 wherein the rigid structural component has a flexural modulus greater than 0.5 GPa.
4. The J-hook retainer of claim 1 wherein the rigid structural component has a flexural modulus from 0.5 GPa to 5 GPa.
5. The J-hook retainer of claim 1 wherein the rigid structure component comprises a component selected from the group consisting of thermoplastic polymers.
6. The J-hook retainer of claim 1 wherein the rigid structure component comprises a component selected from the group consisting of acrylonitrile butadiene styrene (ABS), polypropylene, polyethylene, acetal copolymer, acrylic, nylon, polycarbonate, polyamide, polystyrene, and combinations thereof.
7. The J-hook retainer of claim 1 wherein the rubber section has a Young's Modulus that is less than 0.5 GPa.
8. The J-hook retainer of claim 1 wherein the rubber section has a Young's Modulus from about 0.01 GPa to about 0.1 GPa.
9. The J-hook retainer of claim 1 wherein the rubber section comprises an elastomer.
10. The J-hook retainer of claim 1 wherein the rubber section comprises a component selected from the group consisting of natural polyisoprene rubbers, synthetic chloroprene rubber, polyisoprene rubber, butadiene rubber, butyl rubbers, halogenated butyl rubbers, styrene-butadiene rubber, nitrile rubbers, ethylene propylene rubber (EPM), ethylene propylene diene rubber (EPDM), polyacrylic rubber, silicone rubbers, fluoroelastorners, ethylene-vinyl acetate, and combinations thereof.
11. The J-hook retainer of claim 1 wherein the rubber section is disposed on the shank side.
12. The J-hook retainer of claim 1 wherein the rubber section is disposed on the bite side.
13. The J-hook retainer of claim 1 wherein the rigid structural component includes a barbed that interlocks with a barbed end of a vehicle component for holding the J-hook retainer in place.
