TECHNICAL FIELD
The present invention relates generally to the field of children's accessories, and more particularly to an ergonomic support system for children that is reconfigurable by an adult caregiver to allow adjustment and variation of the system's support structure and support position.
BACKGROUND
As children develop, they typically not only grow physically larger, but also undergo various anthropometric and developmental changes. These changes result in differing needs for physically supporting a child, for example during rest and play, at different stages of their development.
For example, when a baby is first born, their spine will typically have a convex curve in the shape of a C. Newborn infants (for example 0-3 months of age) typically do not yet have the muscle strength to hold up the head, and therefore need head and neck support. Over the next few months after birth (for example 3-6 months), a child begins developing muscle strength in the neck and back, and typically develops a secondary curve of the upper spine (the cervical curve). As the child continues to grow and develop (for example 6-12 months), the child begins to crawl, and the lumbar curve develops in the lower back. Because the child's size and physical support needs change over time, different types of support devices are commonly used for children of different ages.
Different seating and support positions may also be desirable, depending on the child's activity, even for children of the same age. For example, a more flat horizontal support structure may be desired for a child while sleeping on their back, whereas a more upright support structure may be desired during play time for interaction with toys and other persons. And a different support structure may be desirable for tummy time, when a child is positioned on their stomach and learning to push up and raise their head. Various different support devices are commonly used for these different activities.
As a result of these different support needs, parents commonly purchase multiple support devices for children at different stages of a child's development and for different activities. Accordingly, it has been found that needs exist for improved support systems for children that can be reconfigured to fit a growing child, to provide appropriate physical support across a range of developmental stages, and to allow for use in a variety of activities. Needs further exist for continuing improvements to comfort, fit and design in support systems for children. It is to the provision of improved support systems for children meeting these and other needs that the present invention is primarily directed.

With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIG. 1 shows a children's support system 10 according to an example embodiment of the present invention. The system 10 generally comprises a base 20, a child support portion 50, and a toy bar 90. The base 20 comprises first and second side lower support legs 22, 24, a rear lower support cross-member 26, and first and second side upper support legs 28, 30. The first and second side upper support legs 28, 30 optionally comprise extensions of the first and second side lower support legs 22, 24, coupled thereto by intermediate leg portions 32, 34. In example embodiments, at least the intermediate leg portions 32, 34 are flexible and elastically resilient, for example having the form of leaf springs or torsion springs, allowing the support system 10 to function as a bouncer. In particular embodiments, the resilient portions of the base 20 are formed from a shape-memory polymeric elastomer such as for example DuPont Hytrel™. Alternatively, the support base 20 is substantially rigid, and/or includes other motion elements.
The child support portion 50 comprises a support yoke 52 for mounting the child support portion to the base 20, optionally including detachable coupling means allowing the support portion to be removed from and reattached to the base. A support frame 54 is repositionably coupled to the support yoke 52 by pivotal or rotational mounting hubs 56 at each side of the yoke. A positional adjustment mechanism including release actuator 57 allows the support portion 50 to be repositioned between two or more support positions by an adult caregiver. In example forms, the support frame 54 comprises a generally rectangular molding having first and second sides 58, 60, a lower or foot-end cross-piece 62, and an upper or head-end cross-piece 64, defining a central opening within the frame.

The support panel 70 comprises a network of openings for ventilation, temperature modulation, moisture release, and comfort, for example providing larger (about ¼″ to ½″) openings through the lower layer mesh 72 and smaller (⅛″ to ¼″, or smaller) openings through the upper layer mesh 74. The upper layer 74 may be at least partially transparent or translucent, allowing visibility or light passage through the upper layer and through the openings of the lower layer. The multi-layer arrangement of the support panel 70 is optionally configured to be semi-rigid, wherein it is sufficiently flexible and compactable to be collapsed and pressed flat for compact storage and transport, but to retain a three-dimensional architecture and provide shape support for when expanded and mounted to the frame 54. In this manner, the support panel 70 conforms to the size and shape of the child as the child grows, and its contour automatically changes to match postural support needs at different developmental stages and in different activity positions of the child. The child support portion 50 optionally further comprises a harness 80 for retaining a child in position supported on the child support portion. Optionally, repositionable attachment points are provided for attaching an adjustable harness at different locations to accommodate children of different sizes.
The toy bar 90 is attached to the base 20 and/or the child support portion 50, for example by arms of the toy bar coupling with mounting hubs 56 positioned along opposite sides of the support portion. The toy bar 90 is optionally repositionable and/or detachable, allowing for adjustment depending on the size of the child and/or the activity state, or to be removed for cleaning, access or interaction with the child. The toy bar 90 includes one or more toys 92 suspended from or otherwise attached to the upper crossbar. The toys 92 are optionally interchangeable to provide variety and to provide toys suited to the child's developmental stage. For example, large-pattern black and white toys may be more suited to a child in early developmental stages, while more detailed multi-colored toys may be more suited to later developmental stages. Optionally, the toy bar 90 has sufficient structural integrity to also function as a carrying handle, for example supporting about 50 lbs. or more for a sustained duration without detachment. Further optionally, the system 10 includes one or more storage compartments for storing toys not being used.
