Abstract: An upholstered seat system for use on legless leisure chairs. The seat system has features that make it particularly useful on legless leisure chairs having cushioned backrests. The seat system has a seat cushion made of an upholstery fabric filled with a soft resilient material, and further having a flap extending from the back of the seat cushion for attachment to the front lower cross member of a legless leisure chair. The flap provides a flexible means of attaching the seat cushion to the backrest that enables the seat cushion to be folded for storage or transport. The seat system also provides two lower leg support options. One option is to have a two piece seat system including the seat cushion and an ottoman cushion. The other option is to extend the seat cushion to provide continuous support from a user's buttocks to the user's heels. The ottoman cushion can be made with a slip resistant underside. Also disclosed is how the seat system can be made with a multi-layer foam filling, or other fillings.

Abstract: Disclosed is a method for providing various supports in cushions suitable for chairs sofas, and pillows. The method comprises piercing a previously manufactured cushion (86) with injecting needles (84) to inject a firming solution into the cushion (86) to provide the internal lumbar support (88). The needles (84) can be placed at a variety of different heights to product various effects. Also disclosed are a number of products that can be produced using the method, with explanations as to how the method can be adapted to produce each variation.

Abstract: A number of variations of a simple structure for leisure chairs appropriate for both serious indoor use as well as outdoor use. The structure comprises a backrest or occupant supporting member (2) that intersects with and is attached to a countersupporting member (4) in a manner that results in each bearing on the other. Embodiments are disclosed that include armrests (A.P.) as an integral part of the countersupporting member (4). The backrest member (2) is disclosed as straight, with a convex curve in the lower portion (L.P.) of the backrest member (2) to support an occupant's lumbar curve, with a bend between the upper and lower portion to orient the upper portion (U.P.) of the leisure chair at a higher angle than the lower portion (L.P.). A variety of methods of attaching the backrest member (2) to the countersupporting member (4) are disclosed, as are a number of ways of securing the leisure chair in an open position.

Abstract: Upholstery systems for use on chair frames, comprising a support sheet (24) sewn to finished upholstery fabric (30) with a cushion (26) inside the envelope formed by the support sheet (24) and the finished upholstery material (30). The support sheet (24) has ends that are suitable for attaching to cross members (70 & 71) in a manner that will securely hold the upholstery system in place. Additionally, inside the upholstery system there is a securing rod (23) that can be positioned on the support sheet (24) to secure the upholstery system in a desirable position between the sides (72) of a chair frame in a manner that enables the upholstery system to be stretched in a preferred shape. The securing rod 23 is secured to either the sides of the frame (72) or to a cross member (20A) that is secured to the sides (72) of a chair frame. The upholstery system eliminates elements traditionally found in upholstery systems such as fabric on the back of cushions which is normally used in addition to a support sheet (24).

Abstract: Cushions for chairs and the like, having a firm internal support member to support key parts of the user's body such as the lumbar region of the back. These cushions are comprised of: a relatively soft cushion material on the body contacting portion of the cushion, which may or may not be part of; an elastic polyurethane foam type cushion material having a generally tubular cavity or hollow of a predetermined size, shape, and location; and a generally firmer elastic polyurethane foam type internal support member strategically shaped and located in the cavity or hollow of the cushion mentioned above. The cushions are designed for maximum user comfort with the body contacting surface of the cushion being relatively soft, but at the same time the cushions for the back, support the lumbar region so that the user's spine will be in the proper position to minimize strain and discomfort. Essentially the cushions more evenly distribute the load of the person sitting on them in such a way that the back etc.

Abstract: A number of generally wedge shaped backrests and legless leisure chairs for sitting on the floor or on a bed, which orient the user's upper back at a higher angle than the user's lower back. These are ideally suited for people who want to be in a reclining type position, but yet want to do something like watch television. Most of the backrests/leisure chairs described also have a way of maintaining the lumbar region of the user's back in a relatively natural lordotic curve, some through a lumbar support member (28), and others through making a convex contour on the lower portion of the backrest/leisure chair. All of the leisure chairs for sitting on the floor have a seat cushion (34) to prevent the user from slipping down out of place and most have a pillow (32) for a headrest.
