     FIELD OF THE INVENTION  
       [0002]     The present invention relates to child-seat liners. Specifically, the present invention provides protective articles comprising child-seat liners, systems comprising child-seat liners, methods for using child-seat liners (e.g. with a shopping cart), and methods for making child-seat liners. The present invention also provides child-seat liner cut-pieces and patterns.  
       BACKGROUND OF THE INVENTION  
       [0003]     Shopping cart child seats/baskets and shopping cart handles tend to be unclean and dangerous for children. Many types of bacteria, mold, and yeast have been found on shopping cart baskets and handles, including  Coliform, E. coli , and  staphylococcus . Dust, dirt, soil and fecal matter has also been found on shopping cart handles and baskets. Furthermore, the national SAFE KIDS campaign has reported dramatic statistics regarding the dangers of shopping carts for children, such as the fact that at least five children since 1985 have died as a result of shopping cart accidents. Also, in 1998, nearly 25,600 children were treated for shopping cart injuries, with eighty-three percent of the injuries accounted for by children under four years old (according to the national SAFE KIDS campaign).  
         [0004]     Many parents use child-seat liners positioned in the shopping cart basket of a shopping cart in an attempt to protect their child and make their child more comfortable while sitting in the shopping cart basket during a shopping trip. While many child-seat liners are known, many of these are hard to use, don&#39;t satisfactorily protect the child, or may fall out of the shopping cart basket. What is needed is a child-seat liner that is easy to secure to the child seat and that protects the child from contact with unclean shopping cart handles and baskets.

     GENERAL DESCRIPTION OF THE INVENTION  
       [0061]     The present invention relates to child-seat liners. Specifically, the present invention provides protective articles comprising child-seat liners, systems comprising child-seat liners, methods for using child-seat liners (e.g. with a shopping cart), and methods for making child-seat liners. The present invention also provides child-seat liner cut-pieces and patterns. In preferred embodiments, the child-seat liners of the present invention comprise a flap that may be moved between an open and closed position. In preferred embodiments, the open position forms a safety strap opening in the back panel of a child-seat liner. In other preferred embodiments, the child-seat liners of the present invention comprise a safety strap opening (e.g. a single safety-strap opening) that allows at least two safety straps to be pulled through and secured around a child.  
         [0062]     The child-seat liners of the present invention have many advantages over other child-seat liners. For example, in some embodiments, the child-seat liners of the present invention allow a single pair of straps (e.g. that are already attached to a shopping cart or high chair) to be easily retrieved by a user through the safety strap opening. This type of configuration allows the straps attached to a shopping cart basket (or other child seat) to be used to secure both the child-seat liner and the child to the shopping cart basket (or other child seat). In this regard, a user will be much less likely to forget to secure the child-seat liner to the child seat (e.g. since it would be obvious if no straps were around the child). This is advantageous as prior child-seat liners have required a user to secure the child in the child-seat liner with one set of straps (e.g., attached to the child-seat liner), and then secure the child-seat liner to the cart with a second pair of straps (e.g. attached to the child-seat liner or present in the child-seat itself). Having to secure a second pair of straps (e.g. while coping with a child) is less than ideal and may be dangerous. A user may forget to secure the second pair of straps, thus risking that the child-seat liner will fall out of the child seat (e.g. shopping cart basket), along with the child. This unnecessarily risks injury or death for the child. Furthermore, trying to secure a second pair of straps in the back of child-seat liner wastes time and is difficult as a user usually has to maneuver around to see the straps in order to connect them. This may become even more difficult if a user is attempting to hold a child while securing a second set of straps in the back of the child-seat liner. The child-seat liners of the present invention avoid these problems and allows, in certain embodiments, a user to simply reach through a safety strap opening and retrieve a single pair of straps that may be used to secure both the child-seat liner and child to a child seat (e.g. shopping cart basket). In this regard, in certain embodiments, safety straps attached to a child-seat may be used to simultaneously secure the child and child-seat liner to child-seat.  
         [0063]     In certain embodiments, the child-seat liners of the present invention do not contain attached safety straps. This is an improvement over many previous child-seat liners. For example, manufacturing is simplified and costs are reduced since safety straps do not need to be included. Also, as mentioned above, manipulating a single set of straps saves time and energy for a user.  
         [0064]     The child-seat liners and child-seat liner cut-pieces of the present invention are not limited to any particular configuration. Exemplary configurations are shown in  FIGS. 1-5  (described in more detail below). Any type of child-seat liner may be modified in accordance with the present invention. For example, child-seat liners may be modified by the addition of a flap in the back (e.g. placing a flap over existing safety strap openings, or cutting a safety strap opening such that a flap is generated). Also, child-seat liners may be modified by creating a single safety-strap opening in the back large enough for two safety straps to pass through. Child-seat liners may also be modified, for example, by removing the safety straps that may be attached to them (i.e. since they would not be necessary if a flap and/or safety strap opening is used in accordance with the present invention). Examples of commercially available child-seat liners (e.g. that may be modified with the teachings of the present invention) include: BUGGYBAGG seat liners available for sale on the internet (that also converts into a diaper bag, see also U.S. Pat. No. 5,829,835 to Rogers et al., herein incorporated by reference for all purposes); FLOPPY SEAT seat liners sold by Floppy Products Inc., Scottsdale, AZ, see also, U.S. Pat. Nos. 5,967,606 and 6,129,418, both to Bergh et al., and both of which are herein incorporated by reference for all purposes; CLEAN SHOPPER seat liners sold by Babe Ease, LLC, Pelham, HH, (See, also, U.S. Pat. No. 6,129,417, to Cohen-Fyffe, herein incorporated by reference for all purposes).  
         [0065]     Additional child-seat liners (e.g. that may be modified according to the present invention), are found in U.S. Pat. Nos. 5,678,888; 6,206,471; 6,164,721; 4,416,462; 5,967,607; 5,547,250; 6,237,998; 4,204,695; 6,129,417; 6,036,264; 5,897,165; 4,655,502; 4,666,207; 5,330,250; and 4,805,937, all of which are herein incorporated by reference for all purposes.  
         [0066]     The present invention also provides methods of making child-seat liners, and in particular, high volume methods of making child-seat liners. Generally, a child-seat liner pattern is employed (e.g. the pattern serves as a guide for a cutting device to cut a cut-piece). One method of cutting out the cut-piece employs a steel rule die and a steel rule die press. The steel rule die is configured into the shape of the pattern (See, e.g.  FIG. 5B  for an exemplary shape of steel rule die for a child-seat liner). About 10-12 layers of fabric may be laid on a press and the press brought down such that the steel rule die cuts through all of the layers (resulting in 10-12 child-seat liner cut-pieces in the shape of the steel rule die). Another method for cutting out the cut-pieces from layers of fabric (or other material) employs a system called Gerber cutting. Gerber cutting is a system where about 3-5 layers of fabric (or other material) are laid on a table like component and a sheet of plastic is put over the textile (or other material). The plastic is then vacuum shrunk or compressed to remove air. Then a cutting knife driven by a computer program cuts out the various cut-pieces from the fabric (or other material). Another method for cutting out cut-pieces employs laser cutting. In this method, the pattern is programmed into a computer, and then the computer controls the laser as it cuts the fabric (or other material) into various cut-pieces.  
         [0067]     The present invention also provides methods for constructing child-seat liners from various cut-pieces. For example, three child-seat liner cut-pieces may be cut-out. One of the cut-pieces may be a softer material, and be used on the interior of a child-seat liner. One of the cut-pieces may be a durable material and be used for the exterior of a child-seat liner. The third cut-piece may be a filler material, and be used between the other two components in order to cushion the finished child-seat liner. The child-seat liner may be constructed, for example, by combining the softer material cut piece with the filler material (e.g by sewing these two together) to create a composite. The durable material cut-piece may then be sewn to itself in the shape of a child-seat liner, but be inside-out. The composite may then be placed on top (or inside) of the sewn durable fabric piece, and then sewn on three sides (e.g. along the seams). The durable fabric piece in then turned right side out, and further sewing completed (e.g. attaching a handle cover, or rear pouch, or simply sew up any remaining seams).
