  • Patent number: 5469591
    Abstract: It is the object of the present invention to present a bottom structure which allows a bed bottom to be bent at desired curvatures. This is achieved using a bendable bottom component 6 located between the back and waist portions and/or waist and leg portions of a bed bottom 2 which is comprised of parallel rigid strips 7 and flexible strips 8 located between the respectively adjacent rigid strips 7. The flexible strips 8 are formed as bendable sheets 9 connecting the respectively adjacent rigid strips 7 on the side to form the inside curve of the bottom. Guard rails 10 are provided longitudinally to cover both the ends, in the width direction of the bed, of the bendable bottom component 6. End contacts 11 of the guard rails 10 are engaged with the rigid strips 7, and have end caps 12 attached. The end contacts 11 are adjustable and connected with each other by connecting rods 15. The end caps 12 are formed to be thinner at the overlapped portions than the other portions.

  • Patent number: 4995926
    Abstract: In a seat for use in an automotive vehicle, a trim cover is bonded at least at its seat base partly only to a molded polyurethane foam functioning as a seat cushion member and is not substantially bonded at its flap and side parts to the molded polyurethane foam, so that an internal defect can be easily repaired by merely stripping off a corresponding portion of the trim cover. The trim cover may consist of a cover member only, or a filler pad may be only locally bonded to the cover member. The molded polyurethane foam may be formed by foaming and molding a polyurethane resin solution or may be supplied in the form of a slab.
