Similarly, any steps described herein may be interchangeable with other steps, or combinations of steps, in order to achieve the same or substantially similar result.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of exemplary embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that many embodiments of the present disclosure may be practiced without some or all of the specific details. In some instances, well-known process steps have not been described in detail in order not to unnecessarily obscure various aspects of the present disclosure. Further, it will be appreciated that embodiments of the present disclosure may employ any combination of features described herein.

One representative embodiment of a collapsible seat, generally designated 20, constructed in accordance with the present disclosure is illustrated in FIGURE 1. Generally described, the collapsible seat 20 comprises a bottom 24, sides 26 that upwardly extend from around the perimeter of the bottom 24, and a top 28. The top 28, in cooperation with the sides 26 in some embodiments form a concavity 32 suitably dimensioned and configured for receiving and supporting an infant and/or the like. An optional restraint 36 and a headrest 40 may be provided to secure the infant while placed in the cavity 30 and to support the head of the infant, respectively. As will be described in more detail below, the collapsible seat 20 is configured so as to obtain a relatively compact unit for convenient storage and easy transportation during periods of non-use, as shown in FIGURE 7.

Turning now to FIGURES 2 and 8-15, one example of the collapsible seat 20 will be described in more detail. As best shown in FIGURE 2, the seat 20 may comprise an inflatable seat structure 46 and an outer covering 50. The inflatable seat structure 46 may be formed by an inflatable base section 54 mountable below an inflatable upper section 56. The inflatable base section 54 in one embodiment is generally oval, as shown in the bottom view of FIGURE 11 , and is generally symmetrical about its longitudinal axis. The inflatable base section 54 may be formed with rounded side walls 60 that interconnect generally flat, parallelly disposed bottom and top walls 62 and 64. The flat bottom wall 62 includes a bottom surface configured to be supported by a support surface, such as a floor of a room, a top of a table, etc. The bottom wall 62, side walls 60, and top wall 64 are constructed of an impermeable, flexible material, such as polyethylene or plasticized polyvinyl chloride (PVC) film, and are glue bonded, adhesive bonded, heat sealed, or otherwise connected in order to form an air tight cavity 68 (See FIGURE 14). The inflatable base section 54 is sized and configured for having the strength and stability to support the weight of the inflatable upper section 56 and infant when in use. An air valve 74 is provided for inflating and deflating the air tight cavity 68 of the inflatable base 54.

The inflatable upper section 56 is glue bonded, adhesive bonded, heat sealed, or otherwise connected to the inflatable base 54. The upper section 56 is comprised of a bottom wall 76 (optional), side walls 78, a front wall 80, a back wall 82, and an upper or top wall 84. The walls 76-84 are formed of an impermeable flexible material, such as polyethylene or plasticized polyvinyl chloride (PVC) film, and can be easily fabricated and joined by glue bonding, adhesive bonding, or heat sealing techniques known in the art, among others, in order to form an air tight cavity 88 (See FIGURE 14). The inflatable upper section 56 includes a resealable air valve 86 disposed in fluid communication with the cavity 88. Alternatively, the upper section 56 and the base 54 may be interconnected in such a way as to permit inflation of via one of the resealable air valves 74 or 86.

As best shown in FIGURES 2 and 8, 14 and 16, the walls 78-82 of the inflatable upper section 56 upwardly extend from an outer perimeter region of the base section 54. In the embodiment shown, the outer perimeter region of the base section 54 is generally oval. The outer surfaces of the walls 78-82 each have an outward or somewhat convex curvature, the back wall 82 extending higher than the front wall 80, and with a generally wider curve. As shown in FIGURES 15 and 16, the upper section 54 is symmetrical about its longitudinal axis.

The top ends of the walls 78-82 define an oval or egg-shaped opening 92 of a concavity or well 90 when inflated. In the embodiment shown, the well 90 is somewhat shaped like an oval bowl, formed by the concave top wall 84. In that regard, the outer perimeter of the top wall 84 is generally oval or egg-shaped, and is cooperatively sized to interface with top ends of the walls 78-82, thereby forming the opening of the well 90. As shown in the cross sectional view of FIGURE 16, the top wall 84 generally curves in a concave manner from side wall 78A to side wall 78B as the top wall 84 extends from the front wall 80 to the back wall 82. In some embodiments, the top ends of the side walls 78A and 78B, along with the front wall 80 and top wall 82, contiguously connect to the outer, oval perimeter of top wall 84 via a top surface 94. As the top wall 84 extends from the front wall 80 to the back wall 82, the top wall 84 forms a shorter, frontwardly inclined front inner wall section 96 (curved from side wall to side wall as shown, for example, in FIGURE 16) that supports the infants legs, and a longer, generally backwardly inclined, inner wall section 98 (curved from side wall to side wall as shown, for example, in FIGURES 16-18) that supports the infants back, as shown in the longitudinal cross-section view of FIGURE 14. The inner wall sections 96 and 98 join at the bottom 100 of the well with a general curvature for supporting the buttocks region of the infant. In one embodiment, the curvature has a radius of between about 120mm and 180 mm along the longitudinal center line or axis, designated 104 in FIGURE 10, of the upper section 56.

As inflated, the well 90 is suitably dimensioned and configured for receiving and supporting an infant and/or the like while lying in a somewhat prone to inclined, forwardly facing position. In some embodiments, the back inner wall section 98 of the well 90 supports the infant at an inclined angle of between about ten (10) degrees and about 60 degrees, although other angles of inclination are within the scope of the disclosed subject matter. As best shown in FIGURES 1, 8, and 9, the well 90 is sized and configured to somewhat cradle and ensconce the infant in a somewhat seated but inclined, supporting position when placed therein. FIGURES 20A-20B illustrate another embodiment of the inflatable seat structure 146. The inflatable seat structure is substantially similar to the inflatable seat structure 46 except for the differences that will now be explained. As shown in FIGURES20A-20B, the upper or top wall 84 of upper section 56 described above is optional. In that regard, the top wall 164 of base section 154 may form the bottom surface of the concavity 190. As such, the front, back, and side walls 178-182 have a somewhat tubular shape, defining cavity 188. In this embodiment, the cavity 188 is generally shaped as an oval ring.

Referring now to FIGURES 1-7, the inflatable seat 20 may optionally include the outer covering 50. The outer covering 50 is sized and configured to overlay at least the upper section 56 is a somewhat snug fashion so as to be somewhat secured to the upper section 56 when the upper section 56 is generally inflated, and in some embodiments, when the upper section 56 is fully inflated. In one embodiment, the outer covering 50 is lace locked to the upper section 56. Alternatively or additionally, snaps, hook and loop fasteners, etc., may be used in other embodiments to releasably secure the outer covering 50 to the upper section 56. As best shown in the rear view of FIGURE 6, the covering 50 may provide access to the resealable valve 86. In other, embodiments, the outer covering 50 may be sized and configured to overlay both the base section 54 and the upper section 56. In some embodiments, the outer covering 50 overlays both the upper section 56 and base section 54, as shown in FIGURE 19.

Preferably, the outer covering 50 may be generally soft to the touch and aesthetically pleasing to the infant and/or the like. In one embodiment, the outer covering 50 is constructed from a durable fabric, such as Cordura®. Other materials may be additionally or alternatively employed, including fleece, Polar fleece or other microfiber material, wool, lambs wool, cotton, nylon, polyester, etc. The outer covering 50 may be designed with patterns, such as stripes, Polka dots, among others, or may be themed, such as with general characters, such as a mouse, cat, dog, etc., or with branded themes such as Disney® characters and the like.

Referring now to FIGURES 1-3, the collapsible seat 20 may include additional features, such as a restraint 36 and/or a head rest 40. In the embodiment shown, the head rest 40 is a pillow or other head support structure capable of supporting the infant's head when the infant is placed in the well 90. The head rest 40 is stitched or otherwise secured to the covering 50 at a position on the back wall 92. In some embodiment, the head rest 40 can be an inflatable body, foam padding, and/or the like, and covered, for example, with a soft fabric covering.

The restraint 36 may be any restraint currently employed in infant, baby, and or toddler seats, for restraining the infant in the seat 20 when placed therein. The restraint 36 may also support the infant in a generally inclined position, among others. In some embodiments, the restraint 36 may include a harness system of the three point type or the five point type. In the embodiment of FIGURES 1-4, the restraint 36 includes leg openings and straps that are positionable around the infant's waist or stomach. The restraint 36 may be stitched or otherwise secured to the outer covering 50 at a proximal portion of the well 90. In other embodiments, the restraint 36 and the head rest 40 are releasably secured to the outer covering 50 in any of a variety of connection techniques known in the art.

Using the collapsible seat 20, which is constructed in accordance with aspects of the present disclosure, will now be described with reference to FIGURES 1-19. When the collapsible seat 20 is not in use, the collapsible seat 20 can be stored in a deflated condition. In the deflated condition, the collapsible seat 20 can be folded, rolled, or otherwise manipulated into a compact, stowable, condition, including, floor example, as shown in FIGURE 7. If desired, the collapsible seat 20 in the compact, stowable, condition can be placed within a storage bag for easy transport, etc. In embodiments where the headrest 40 and/or the restraint 36 are removable, these features may be removed prior to deflating and placed within the storage bag for subsequent use. In some embodiments, the collapsible seat 20 includes straps 108 or other structure that maintains the collapsible seat 20 in the compact, stowable, condition. In these embodiments and others, the straps or other structure may either be attached to the seat 20, or detached from the seat 20.

When the collapsible seat 20 is needed for supporting an infant or the like, the base 54 and the upper section 56 are inflated via the valves 74 and 86. This can be readily accomplished by manually exhaling into the valves 74, 86 or by using an auxiliary air system, such as an air pump or with the exhaust port of a wet/dry vacuum. The inflation of the base 54 and upper section 56 will cause the collapsible seat 20 to expand, thereby erecting the walls and forming the well 90. The optional cover 50 may then be placed over at least the upper section 56, and in some embodiments, over both the base section 54 and the upper section 56. The infant may then be placed within the well 90, and if employed, the infant may be positioned so as to be restrained by the restraint 36 and/or have its head supported by the headrest 40.

After use of the collapsible seat 20 and the infant is removed from the collapsible seat 20, the collapsible seat 20 may be deflated by opening the air valves 74 and 86, permitting air within the cavities 68 and 88 to be released. After the collapsible seat 20 is deflated, the collapsible seat 20 may then be folded, rolled or otherwise manipulated into a relatively compact unit for convenient storage and transport during periods of non-use. Prior to storing the collapsible seat 20, the collapsible seat 20 may be cleaned and/or sanitized, as desired.
