  • Patent number: 6394867
    Abstract: A vehicle seat comprising a seating substrate, an outer seat covering, and a housing containing an integrated self-inflating floatation device. The self-inflating flotation device includes one or more inflatable flotation bladders and an inflator that is activated to automatically inflate the one or more inflatable flotation bladders when the seat or a vehicle to which it is attached is immersed in water. The one or more inflatable flotation bladders are releasably received and secured within the housing when the bladders are deflated. The housing is received within the vehicle seat such that upon activation of the inflator the one more inflatable flotation bladders inflate and are completely released and detached from the housing and from the vehicle seat.

  • Patent number: 6382531
    Abstract: A shower head generally comprising a backing plate, a diaphragm and a cover plate. The rear surface of the backing plate includes a receptacle for receiving a conduit through which pressurized water may be directed to an aperture extending through the backing plate. The front surface of the diaphragm has a plurality of nipples extending outwardly therefrom with each nipple having longitudinal bore extending therethrough. The cover plate has a plurality of holes extending therethrough for receiving the nipples on the diaphragm such that the cover holds the diaphragm against the front surface of the backing plate. Pressurized water delivered through the aperture causes an outward deflection of the diaphragm away from the backing plate allowing water to be expelled through the bores in the nipples.

  • Patent number: 6328130
    Abstract: An accessory for releasably securing to a ladder. The accessory has at least one stabilizing arm for stabilizing and supporting the ladder when leaned against a building or structure. The stabilizing arm has a generally U-shaped configuration with a pair of generally parallel leg members that are spaced apart by a distance approximating the distance between the centers of adjacent ladder rungs. Each of the leg members ends in a ladder rung engaging member having a fore and an aft end, and is receivable within the hollow interior of a ladder rung. The ladder rung engaging members are oriented in a convergent configuration such that inserting them the hollow interiors of a pair of ladder rungs causes the fore and aft ends of the ladder rung engaging members to bind against opposite sides of the interior surfaces of the ladder rungs, and to releasably secure the stabilizing arm to the ladder.
