Abstract: Described are crossbeam assemblies for installing a furnishing to a passenger compartment. The crossbeam assemblies can include a first structural member configured to span two floor-mounted channels in a passenger compartment, and at least two attachment elements that are slidingly connected with the first structural member. The attachment elements are repositionable along the first structural member to mate with the floor-mounted channels, and lockable to retain the first structural member with respect to the two floor-mounted channels when the first structural member is attached.

Abstract: An apparatus and a system are disclosed for protecting the side doors of an automobile when it is parked. The apparatus includes an elongated pad having two opposing ends and a central portion disposed between the two endings, and a protrusion extending from the central portion of the elongated pad and formed of a material sufficiently compressible to be shut within the door of an automobile. The system includes an elongated pad having two opposing ends and a central portion disposed between the two endings, and an adjustable protrusion extending from the central portion of the elongated pad, the adjustable protrusion movable to different locations along the length of the elongated pad, the protrusion is formed of a material sufficiently compressible to be shut within the door of an automobile.

Abstract: An apparatus, system, and method are disclosed for protecting the side doors of an automobile when it is parked. Dings, scratches, and dents are common in parking lots where multiple cars are parked within close proximity to one another. The current invention protects the sides of a car from those dings, scratches, and dents that occur when a neighboring car's door is opened too wide. The current invention is easy to use and several embodiments offer methods of quick and easy storage. All embodiments of this invention are made primarily out of pliable, soft foam that is weather resistant and smooth enough as to not damage the surface of the car. Rather than using straps or clamps to attach this invention to the car door, this invention features a centrally located protrusion from the foam protection pad that can be shut in the car door.
