     FIELD OF THE INVENTION 
     The present system relates to a child carrier, and more specifically, to a child carrier which enables a child to be carried in the posture of sitting in a chair, on the users back and to also be useable with the child on the front of the user, facing the user. The system enables transport of Infants/children between 8 pounds and 40 pounds in weight. The system also relates to the choice of construction materials and construction methods of this carrier that enable it to to be rolled and compressed into a small storage sack for efficient storage and transport when not in use. 
     BACKGROUND OF THE INVENTION 
     In general most soft child carriers are constructed of somewhat stiff and/or highly padded materials. In addition most provide highly padded shoulder straps and a wide and highly padded waist belt to support a portion of the child&#39;s weight. Such carriers provide adequate support and comfort but are not conducive to compressibility and portability due to their large size and bulky construction. 
     BRIEF SUMMARY 
     The system incorporates a child carrier worn on the back of the user for supporting and transporting a child including a child seating and back support portion, an adjustable waist belt portion, two adjustable padded shoulder straps, a dual-adjustable cross-chest sternum strap, and two infant/child leg restraint straps. The child carrier is compliant to support the child from bottom, rear and side. The carrier preferably uses shoulder and waist straps constructed of 3d air mesh fabric to provide adequate support and comfort, which enables the child carrier to be compressed into a small sack for stowage and transport in a pocket or other location.

     DETAILED DESCRIPTION 
     To solve the limitation as described in the Background section, it is an object of the system to provide a child carrier that is designed to be highly compressible and portable. 
     It is another object of the present system to provide a child carrier that enables a child to sit be comfortable and close to the caregiver, allowing freedom of movement for the arms of the child 
     It is still another object of the present system to provide a child carrier that alternately carries a younger child on the caregiver&#39;s front, with the child and caregiver facing one another. 
     To accomplish this and other objects, the child carrier, best referenced in  FIG. 1 ,  FIG. 2 , and  FIG. 3 , according to the present system includes a flexible fabric body panel ( 5 ) that supports the child from the rear and bottom. In the preferred embodiment, the body panel is constructed of one layer of strong support fabric of ripstop nylon or equivalent, and one layer of breathable lightweight mesh fabric for comfort. 
     Body panel ( 5 ) includes two separate portions. The first portion is upper portion ( 10 ), which includes an upper edge ( 10   a ), right edge ( 10   b ), and left edge ( 10   c ). The second portion of body panel  10  includes a lower hip portion ( 15 ). Lower hip portion ( 15 ) is approximately trapezoidal in shape, with a taper that gradually creates a narrow width than the full width of body panel ( 5 ). The narrowest part of lower hip portion ( 15 ) is at lower edge ( 10   d ). 
     Upper portion ( 10 ) and lower portion ( 15 ) are preferably constructed from a single piece of fabric, however multiple pieces may be joined together to create the entire body panel, with joints either at the junction ( 18 ) of the upper and lower portions, or elsewhere. In the preferred embodiment, the lower portion curves relative to the upper portion at approximately 180 degrees along fold ( 20 ). 
     The child carrier includes a right shoulder strap ( 30   a ) and a left shoulder strap ( 30   b ). The upper end of each shoulder strap is attached to the upper edge of the body panel ( 5 ), near the intersecting point with right edge ( 10   b ) and left edge ( 10   c ) respectively. The lower end of each shoulder strap connects to right edge ( 10   b ) and left edge ( 10   c ) respectively. The shoulder straps are formed in an S-curve shape and are primarily constructed of 3d air mesh type fabric, which preferably is slightly stretchable. The shoulder straps include length adjustability, and also a sliding and adjustable sternum strap ( 35 ) that connects the shoulder straps together in the front of the caregiver, across the upper sternum, or across the back for the front carry position. 
     The child carrier further includes a hip belt ( 40 ), which attaches to body panel ( 5 ), and is preferably constructed of 3d air mesh type fabric. Each end of hip belt ( 40 ) is connected around the user with adjustable narrow straps and a buckle ( 45 ), with the buckle adjustable and separable. Belt ( 40 ) and body panel ( 5 ) preferably connect at fold ( 20 ); specifically, the belt is attached to the lower portion ( 15 ) of body panel ( 5 ), immediately adjacent to fold ( 20 ). Thus, body panel ( 5 ) does not end at belt ( 40 ), but rather continues past belt ( 40 ) in the form of lower portion ( 15 ). This configuration creates a load path (which will be further described later) that pulls down on the bottom of the hip belt ( 40 ), and also maintains a flat hip belt against the body of the adult. Thus, a more comfortable hip belt is created without the use of wide, stiff, or heavily padded materials. 
     In the preferred embodiment, belt ( 40 ) is sewn to body panel ( 5 ), though other means known in the art such as riveting, bonding, etc. could be used. Belt ( 40 ) is not sewn edge-to-edge to the full width of body panel ( 5 ), rather the belt is sewn only to a fraction of the full width of body panel ( 5 ). This can be seen in  FIG. 1 , where the dashed lines, forming a rectangular shape, represent the stitching of belt ( 40 ) to the body panel ( 5 ). Here, the vertical side stitches are clearly seen as creating a union more narrow than the full width of body panel ( 5 ), even as the sides of lower portion ( 15 ) is tapering in its trapezoidal shape. 
     Further features of the system include left restraint strap ( 60   a ) and right restraint strap ( 60   b ). As seen in  FIG. 4 , the carrying system may be configured detached to body panel ( 5 ). In this arrangement, an enlarged sized opening (as compared to the restraint straps configured attached to body panel ( 5 ), as will be further explained) is created for a child&#39;s legs. When right and left restraint tabs are configured attached to body panel ( 5 ), as seen in  FIG. 5 , a reduced sized opening is created for a child&#39;s legs. Thus, when carrying a younger, smaller child, the straps may be attached to create a smaller leg opening. When the child is older and larger, the system may be configured with the restraint straps detached, to create a larger opening, corresponding to the larger size of an older child&#39;s legs. 
     Restraint straps  60   a  and  60   b  bridge between the shoulder straps and the mid portion of the body sheet via adjustable buckles. Here, the size of the leg opening for a child is further enabled by lower hip portion ( 15 ). With the restraint straps attached, as seen in  FIG. 1-3 , lower hip portion ( 15 ) is positioned between the body of the child and the body of the adult, wrapping between the child&#39;s legs. With the restraints straps detached, as seen in  FIG. 5 , the lower hip portion ( 15 ) unobtrusively tucks underneath the child&#39;s bottom, with its exact position not relevant in this configuration. 
     The pack is configured to be used either on the back or on the chest of an adult, where an adult means any appropriately aged and sized person suitable to give care to a child who may appropriately fit in the carrying system. The child system may be used by various shapes and sizes of caregivers, and children, with a stated age limit and weight limit, through adjusting attachment straps. The system being convertible between front and back carrying positions creates additional benefits compared to a front-only or back-only system. A front carry position may be best suited to babies and small children, which provides better parent-child interaction, and also may enable breastfeeding during wear. As a child ages and is more suited to carrying on the adult&#39;s back, which is typically more comfortable than carrying on the adult&#39;s front, there is no need to purchase a new carrying system. 
       FIG. 4  also shows optional hood ( 90 ), an approximately trapezoid shaped sheet with a top edge, a bottom edge and two side edges. The side edges include elastic sewn in to provide gentle support for a child&#39;s head. The bottom edge has two tabs of lightweight webbing which are attached via snaps through either of two sets of attachment loops to an optional pocket on body panel ( 5 ). Different Loops may be used depending on the size of the child (upper loops being for larger children, lower loops for smaller children). The top edge has attached two lengths of lightweight webbing with snap sides along its length, and attach to the snap sides installed in the shoulder straps  30   a  and  30   b .l A number of snaps along its length provide for adjust ability. The hood can be stowed inside the pocket when not in use. The hood may serve to give the child added comfort, light head support, or shelter from the elements. 
     The system is of a minimalist design, and along with the choice of fabric materials and construction techniques, allows the child carrier to be rolled and compressed into a small state, allowing convenient and efficient packing and storage. This enables the child carrier to be carried at present within a purse, basket or diaper/travel bag. When rolled into a compact form, the carrying system may be placed inside a cylindrical sack ( 80 ), as seen in  FIG. 10 , that measures seven inches long by three inches in diameter, or seven inches by three inches by three inches. 
     The system also creates a preferred load path along the length of body panel ( 5 ). A child&#39;s weight, or load, slightly stretches the fabric material of body panel ( 5 ) to distribute load forces across the child&#39;s back and hips, and pull the child close to the parent, for closeness, comfort, and stability. The system also creates a load path, between the right and left shoulder straps and the hip belt, that does not coincide with the edge of body panel ( 5 ). This is accomplished with a wide body panel ( 5 ), which places the load path on the inward portion of body panel ( 5 ), away from right edge ( 10   b ) and left edge ( 10   c ). There is also evidence that the configuration better distributes the pressure on a child&#39;s legs, thereby reducing red marks caused by a tensioned fabric edge “digging-in” to the child&#39;s legs as with to other carriers. Further, the system provides knee-to-knee support for infants, and may reduce hip dysplasia and uncomfortable pressure in a child&#39;s groin area. 
       FIGS. 6, 7, 8, and 9  provide additional views of the carrying device.
