  • Patent number: 7416248
    Abstract: The adjustable configuration seating has a pair of opposed lateral rigid frame members with seat and back panels extending therebetween. In some embodiments, the chair includes flexible panels secured in place between the two frame members by crossmembers extending between the frame members, with a single adjustably positionable tension crossmember also extending between the frame members to hold the seat and back panel taut. Conversion between relatively upright and reclining configurations is accomplished by repositioning the tension crossmember between the frames, and turning the assembly ninety degrees to position the selected seating surface to face generally upwardly. Other embodiments have rigid seating and back panels, with the backrest panel articulating between the frame members to allow the seating configuration to change. The backrest panel may be secured to the seating panels by a rigid or flexible intermediate panel.

  • Patent number: 4839934
    Abstract: The invention is an improved bed covering multiple component comforter formed with a container-cover unit containing removable and interchangeable insulator pad units enclosing heat insulating material such as down. The pads are each held in place in compartments or channels of the container-cover. The pad units may be removed prior to washing or dry cleaning of the container-cover. Similarly, the pad units may be washed independently of the container-cover, when removed. The container-cover may be made of one of a number of different decorative fabrics, with the user applying the pads units into the particular container-cover that is to be used at the moment. Each compartment opening through which a pad unit is to be inserted may be fitted with a flap that overlaps the opening of the compartment to prevent inadvertent removal of the pad. A flexible tape device may also be employed to fasten the openings of the compartments in use.
