Abstract: Disclosed herein are apparatus for attaching covering material to interior components of a vehicle. One embodiment is a speaker grille for concealing a speaker in the interior of a vehicle. The speaker grill comprises a first surface and a second surface opposite the first surface. At least one projection extends from the second surface. The projection has a base at the second surface and a distal end opposite the base and a retention member extending directly from the projection at a location proximate to the base and spaced apart from the distal end. The retention member has a retention surface spaced apart from and substantially parallel to the second surface. A covering overlies the first surface and defines an aperture through which the projection extends. A portion of the covering is positioned between the second surface of the substrate and the retention member.

Abstract: Apparatus and method for attaching a covering material to interior components of a vehicle, such as a speaker grille, seat or other substrate. The interior component has a first side configured to face the interior of the vehicle and second side facing away from the interior of the vehicle. One or more anchor members project from the second side of the substrate, each of the anchor members having at least one retention member. The covering material has apertures disposed about a central portion. The covering material is wrapped around the substrate so that the central portion of the covering material overlays at least a portion of the first side, and each of the anchor members and its retention member are inserted through one of the apertures to secure the covering material to the substrate.

Abstract: For use with sporting equipment having a handle shaft, such as golf clubs and baseball bats, a new and useful underlay material is self adhered to the area of the handle shaft designated for grasping, and used in conjunction with an external handle grip. The underlay material has self adhering surfaces and comes in stacks having a release paper sheet separate the individual underlays. The underlay materials come in a wide array of thicknesses and densities whereby each handle shaft can be custom fitted to its user, and can receive any standard overlay grip. The underlay materials are pre-cut to a designated handle size whereby one can choose the circumference of the handle shaft affording the greatest ergonomic value by first applying the self adhering underlay material to the handle shaft, then applying a small amount of solvent to its outer self adhering surface to act as a lubricant, a common handle grip is stretched over the underlay material until firmly seated thereto.
