Abstract: A ventilated support structure for a vehicle, such as a bicycle, comprising an upper side having a seat surface which is supported on a rigid or semi-rigid frame on which is anchored elastically flexible padding there between. The support structure may further comprise an aperture in an anterior portion of the frame. The aperture may be oriented at least partly in a direction of forward travel of the vehicle. An air distribution channel is connected to the aperture and is also connected to a plurality of air discharge openings to ventilate the seat surface.

Abstract: A toothbrush includes a handle, a head extending from the handle, and a plurality of tooth cleaning elements, such as tufts of bristles, extending from the head. Each tooth cleaning element is supported for rotation about primarily only one axis. Each tooth cleaning element is rotatable independent of the other tooth cleaning element(s).

Abstract: A screen apparatus includes a perimeter frame with a notch and arcuate foot in one of the bottom corners that are adapted to receive a raised floor device, such as a raised power outlet. A covering covers the frame but the notch is not covered. The covering is preferably a light-passing translucent sheet of performance fabric which is adapted to pass light sufficient for a viewer to see a person behind the screen, but which scatters and blocks sufficient light to provide privacy by hiding details of the person's work from the viewer. The screen apparatus also includes bowed frame members extending horizontally between some of the outer frame members.

Abstract: A chair includes a seat with male snap connectors thereon and a back. A cushion assembly has female snap connectors shaped to engage the male snap connectors for securement. The cushion assembly includes a dimensionally-stable fabric that holds the snap connectors in a stable pattern, and the male and female snap connectors engage in a manner that locates and secures the cushion assembly on the seat. The cushion assembly is easily and quickly removed from the seating unit, and can be quickly dry-cleaned, washed, or repaired, and reattached to the chair. A back cushion assembly is provided that can be pulled downwardly onto the back, and stretch-attached along its bottom edge. A removable seet through fabric vest can also be pulled downwardly over the back and releasably attach to a bottom edge of the back. A hanger is provided for supporting extra vests, back cushion assemblies and seat cushion assemblies.

Abstract: The present invention is directed to a support structure for a vehicle, such as a bicycle. Specifically, the support structure of the present invention comprises an upper side having a seat surface which is supported on a rigid or semi-rigid frame. An elastically flexible padding is positioned between the seat surface and frame. The support structure of the present invention further comprises an aperture in an anterior portion of the frame. The aperture is oriented at least partly in a direction of forward travel of the vehicle. An air distribution channel is connected to the aperture. The air distribution channel is also connected to a plurality of air discharge openings positioned on the upper side of the seat surface, so that while the vehicle moves forwardly, air flows from the aperture to the discharge openings, thereby ventilating the seat surface.
