Abstract:
A carrying device for transporting an infant child is disclosed. The carrier may be worn on the user&#39;s back or may alternately be fitted to the user so that the infant is carried in front. The carrier includes a pair of adjustable shoulder straps to be worn by the user and also has an adjustable waist band. The outer jacket of the carrier is formed of heavy fabric such as canvas or twill and has an adjustable head support at its upper end. Inside the carrier is a seat-member which may be lowered as the baby grows taller so that the child&#39;s head is always in a position for proper support.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to infant carriers in general and more particularly those providing head support and which are adjustable to compensate for changes in body size as a child grows. 
     3. Description of the Prior Art 
     Numerous child-carrying devices exist in the prior art. Some simply comprise a rigid plastic seat with handles. These are used primarily for carrying very small infants in automobiles or over very short distances. They are generally unsuited to carrying larger children. Others have a rigid metal frame and are designed to be worn on the mother&#39;s back. The baby is carried in a fabric or plastic seat mounted on the metal frame. The seat has a pair of holes through which the infant&#39;s legs extend. Still others are made entirely of fabric and have a pouch in which the infant is carried. Some of these carriers may be worn on the front or back of the user&#39;s body. Support is provided by a pair of shoulder straps. One such carrier is shown in U.S. Pat. No. 3,780,919. 
     SUMMARY OF THE INVENTION 
     A principle object of the invention is to provide a carrier having an adjustable head-support member which provides physical support for the infant&#39;s head from its shoulders along its neck to the base of its skull and up to the back of the head near the child&#39;s ears. 
     A further object of the present invention is to provide a carrier having an inner seat which is adjustable and removable to compensate for changes in a child&#39;s body size as it grows. 
     A further object of the present invention is to provide a carrier having an inner seat which will provide full support for an infant from its buttocks to its shoulder blades when the child is secured in the carrier. 
     Other objects and advantages of the present invention will be apparent to those skilled in the art.

     DETAILED DESCRIPTION 
     Referring now to the drawings, FIG. 2 shows a plan view of the carrier which is composed of a front member (2) and a back member (3). The front member (2), back member (3) and the single piece waist band (33) are sewn together to form a floor (4). On the inside surface of the front member (2) is fastened an inner seat (5). The inner seat (5) is made of heavy fabric and is nominally hour-glass shaped; being wide at the top and bottom and having a narrow section (7) in the middle. The narrow section (7) and outwardly tapering wide bottom (8) of the seat (5) are secured to the inside of the front member (2) with a plurality of stitched seams (9), (10) and (11). A support strap (13) is sewn to the upper end of inner seat (5). Retaining rings (14) are sewn to the inner surface of front member (2) to provide adjustable fastening means used in conjunction with strap (13). A left underarm strap (17) and a right underarm strap (19) are connected at opposite edges in approximately the middle of the front member (2). A left shoulder strap (21) having a fixed shoulder pad (23) and a right shoulder strap (25) having a fixed shoulder pad (27) are sewn to and extend from the upper end of front member (2). Shoulder straps (21) and (25) are sewn to the front member (2) so as to cross each other and form an &#34;X&#34; configuration. This adds strength and eliminates rip-out in this area when the pack is being put on by the user. The two straps (21) and (25) form a &#34;V&#34; where they cross and are joined to front member (2). Underarm strap retaining rings (29) are mounted at the outer ends of shoulder pads (23) and (27). Head strap retaining rings (31) are mounted on the shoulder straps (21) and (25) near the upper end of front member (2). A single piece waist band (33) is stitched into and integral with the seam which joins front member (2) and back member (3) to form the pack floor (4). It will be recognized to those skilled in the art that a two-piece waist band might be chosen as an alternate construction. A left arm strap loop (35) is mounted on the left edge of back member (3) normally half way between the top and bottom of the back member (3). A similar right underarm strap loop (37) is mounted in a similar position along the right edge of back member (3). A head support (39) is joined to the upper end of back member (3) at seam (41). Head support (39) is formed of a single piece having a straight bottom edge (43). Support (39) is cut to form a thin left head support strap (45) and a right head support strap (47). Head support (39) gradually widens the outer ends of strap (45) and (47) toward the middle to form a broad center section (49) having a symmetrical curved upper edge (51). The head support (39) is interfaced with strong, but pliable, material for added support. 
     USE OF THE CARRIER 
     FIG. 2 illustrates the use of the carrier with a small, very young infant. The carrier is placed on a flat surface, unfolded and spread out. The infant is placed on front member (2) and the inner seat (5) folded over the child&#39;s body. The support strap (13) is positioned across the infant&#39;s upper back; in the figure, just below the arm pits. Strap (13) is now fastened to retaining rings (14). It will be appreciated that because of the nature of this construction, rings (14) and straps (13) may be adjusted to accommodate both large and small infants securely and confortably. It is contemplated that the back and buttocks of a small infant will be supported by the narrow section (7). However, as the infant grows larger, seams (9), (10) and (11) may be progressively removed so that an increasingly wide portion of the bottom section (8) becomes available to support the child&#39;s buttocks and back as the child increases in size. As the child grows taller, this ability to adjust the seating position downward allows the head to always be properly supported by the cup-like head support (39). It will be appreciated that eventually the inner seat (5) may be completely removed and the child will sit on the floor (4). With the infant securely positioned in the inner seat (5), the back member (3) is folded up over the child. Head support (39) is positioned about the child&#39;s shoulders so that center section (49) extends upward along the child&#39;s neck and the base of the skull. As illustrated in FIG. 1, curved edge (51) is then at the back of the head near the level of the infant&#39;s ears. This will vary somewhat with infant size and the position of the carrier on the user. Left and right head support straps (45) and (47) respectively are then joined to head support rings (31) and adjusted to a length suitable to provide proper support for the child&#39;s head. 
     When properly positioned, head support (39) provides a strong, pliable cup-like structure which will support the child&#39;s head from his neck up the base of the skull to the lower back of the head. Lateral support of the head is also provided by center section (49) and straps (45) and (47). Head support (39) may be adjusted to bring the child&#39;s head close to the user&#39;s back. For larger children, support (39) may be adjusted away from the user&#39;s back to provide for extra freedom of movement. 
     The shoulder straps are operatively connected as follows. Left underarm strap (17) is passed through left underarm loop (35) and joined to shoulder strap retaining rings (29) located at the end of the left shoulder strap (21). Right shoulder strap (19) is similarly passed through right underarm loop (37) and joined to retaining rings (29) at the outer end of right shoulder strap (19) as illustrated in FIG. 4. Underarm straps (17) and (19) in conjunction with loops (35) and (37) and shoulder straps (21) and (25) now form a pair of strong supporting members for the carrier. When straps (17) and (19) are drawn up they pull back member (3) in toward front member (2) to form a secure outer pouch. The user simply slips his arms through the harness formed by these loops in the same manner as one slips on a jacket. Shoulder straps (21) and (25) may be adjusted by repositioning underarm straps (17) and (19) and retaining rings (29). When the carrier is comfortably in place, pads (23) and (27) will bear against the user&#39;s shoulders and distribute the load evenly across the shoulder areas. With the carrier in place on the user&#39;s back, waist strap (33) is tied around the user&#39;s hips or upper waist and helps to transfer some of the weight of the carrier to the user&#39;s hips. 
     The position of the infant on the user&#39;s back may be adjusted by shifting the infant&#39;s weight and lengthening or shortening the underarm straps (17) and (19) to elevate the position of the infant. Straps (17) and (19) are pulled further out through retaining rings (29). To position the infant lower on the user&#39;s back, the reverse is true. 
     It is readily apparent that the carrier may be worn in front of the user&#39;s body. To accomplish this, the user merely passes his arms through the loops formed by joining shoulder straps (21) and (25) to underarm straps (17) and (19) respectively. The carrier is then lifted into place against the user&#39;s chest and the waist strap (33) is tied behind the user&#39;s back at the hips or waist. 
     Having described the preferred embodiment of the invention it will be apparent to those skilled in the art that other modifications and arrangements may be made without departing from the true scope and spirit of the invention. For example, it would be readily apparent that the various retaining rings herein described could be replaced with buckles or other clasps and devices. Also, although the carrier is preferably made of a heavy fabric, it might alternately be made of plastic or have a mesh insert for warm climates. I claim as my invention all those modifications as come within the true spirit and scope of the appended claims.
