  • Patent number: 5868465
    Abstract: A child's seating restraint is removably anchorable to a stationary article of furniture, such as a couch, sofa, or similar furniture typically found in the household. The restraint in turn provides for the removable securing of an infant, toddler, or small child thereto, to prevent the child from falling from furniture inadvertently. The seating restraint includes a belt secured to the back portion thereof. A continuous, unitary seat bottom and seat back portion is formed of a soft, pliable, resilient and washable material such as a closed cell foam plastic. A washable fabric cover may be provided for the seat bottom and/or seat back portion of the device. A crotch strap may be attached to the belt (or beneath the seat bottom), to extend from the back of the belt (or from the seat bottom) to a front loop through which the belt portions are passed.

  • Patent number: 5715546
    Abstract: A bathtub cushion is formed of a resilient material, such as a closed cell plastic foam. The cushion covers the interior of the bottom of the tub, extending upwardly to cover the interior walls of the tub and the edges or rim of the tub. The cushion may be formed as a sheet of uniform thickness, on the order of one to two inches thick, or may alternatively be formed with a thinner bottom portion and thicker upper walls and upper edge, to better cushion any impact of a bather who might slip in the tub. The cushion is removably secured within the tub by suction cups disposed about the entire tub contact surface of the cushion, and includes drainage grooves formed in the upper surface of the bottom portion to facilitate drainage. The cushion may also include a head rest, which may include a radio, cassette deck, or other audio system therein, as desired.
