  • Patent number: 9752542
    Abstract: A vehicle includes an air cleaner box assembly disposed within an engine compartment. The air cleaner box assembly includes a moveable shell portion and a stationary shell portion. The moveable shell portion includes an upper surface disposed adjacent a hood, and defines a filtered air chamber. The stationary shell portion is attached to a structure, and defines an unfiltered air chamber. A filter element is attached to and supported by the moveable shell portion. The filter element separates the filtered air chamber and the un-filtered air chamber. Each of a plurality of spring loaded guide members slideably connect the moveable shell portion and the stationary shell portion, and guide the moveable shell portion along a path relative to the stationary shell portion, between an expanded position and a compressed position.

  • Patent number: 5577649
    Abstract: An article carrier includes spaced longitudinal rails, at least one of the rails having an upper arm coupled by a hinge to a lower arm. A crossbar having an end portion adapted to be entrained between the upper and lower arm portions includes a conformingly shaped mating surface to one of the members of the longitudinal rail. Preferably, both ends of each crossbar include conforming surfaces that mate with corresponding configurations on the rail to fixedly position the crossbar along the longitudinal rail. The position of the crossbar is easily adjusted by opening the upper member of the longitudinal rail by displacement about the hinge, and the hinge axis may be transversely, longitudinally or vertically aligned as desired. Preferably, two upper arms are provided on a longitudinal rail, hinged at opposite ends of the longitudinal rails, and include overlapping portions retained by a single latch mechanism.
