  • Patent number: 6702347
    Abstract: An integrated mounting system for mounting the bumper, recovery rings and a selectively removable winch to the frame of a motor vehicle. Left and right mounting plates are attached to the front ends of the left and right frame rails, wherein each mounting plate has a plate aperture. Left and right mounting brackets each have a bracket aperture formed in a planar base and a clevis perpendicularly upstanding in relation to the base. The front bumper also has a pair of bumper apertures. With the apertures aligned, the left and right mounting brackets are attached, respectively, to the left and right mounting plates, the bumper being sandwiched therebetween. Recovery rings are attached pivotally by a connector to each clevis. Removing a recovery ring allows a winch stinger to be received into the bracket, bumper and plate apertures at the selected mounting bracket, and be secured thereto via the connector at the clevis.
