Abstract: A uni-brace mechanism is provided which allows a vehicle seat to be attached to the vehicle seat slide adjusters made by various manufacturers. A front bracket and a rear bracket are spaced apart and attached to the underside of a vehicle seat. Each bracket includes two pairs of receiving holes, with each receiving hole having at least one corresponding engagement hole spaced apart from the receiving hole. The various engagement holes combined to form various generally rectangular patterns, spaced at distances to correspond to the bolt patterns found on vehicle seat slide adjusters. A pal nut is inserted into a receiving hole and into engagement with the proper corresponding engagement hole. Pal nut includes a hub with an internal thread which is positioned within the engagement hole. The bolt on the vehicle seat slide adjuster are threaded through the engagement hole and into the hub, attaching the vehicle seat slide adjuster to the bracket.
