DETAILED DESCRIPTION
The disclosed technology is a car seat specifically designed for infants and young children with acid reflux. In embodiments of the disclosed technology (as shown in FIGS. 1A-E) the car seat includes a wedge frame 1 and a removable rectangular frame 2 with a flat surface 2S to support and secure a child, wherein the removable rectangular frame is received by and positioned within the wedge frame so that the child support surface of the removable rectangular frame is at an angle of inclination α of 20-40 degrees relative to the bottom plane P of the wedge frame; in some embodiments the angle of inclination α is between 25-35 degrees, and in some embodiments between 28-32 degrees relative to the bottom plane of the wedge frame. The wedge frame is formed to include front and back ends 1A, 1B and right and left sides 1C, 1D, which ends and sides extend perpendicularly from the bottom plane of the wedge frame. In some embodiments of the disclosed technology the right and left sides of the wedge frame have a height increasing from the front end to the back end at an angle of 20-40 degrees, or 25-35 degrees, or 28-32 degrees; in these embodiments the front end 1A of the wedge frame has a height less than the height of the back end 1B corresponding to the height of the sides 1C, 1D at the points the sides join with the respective end.
As shown in FIG. 3A-C, the wedge frame further includes a support structure 1S to support the removable rectangular frame. The support structure may be positioned on the interior surfaces of the sides of the wedge frame at an angle of inclination α of 20-40 degrees, or 23-35 degrees, or 28-32 degrees relative to the bottom plane P of the wedge frame. The angle of inclination of the support structure may be less than 20 degrees if the angle of inclination β of the child support surface 2S of the removable rectangular frame relative to the plane of the base of the removable rectangular frame is greater than zero, as hereinafter described.
The support structure 1S may be affixed to the opposing interior side surfaces of the wedge frame, or the opposing ends of the frame, or both. The support structure may be structure protruding from the side/end into the interior of the wedge frame a sufficient distance (e.g., 1⁄2′′) to support the removable rectangular frame 2 within the wedge frame 1. The support structure 2S may also be a support surface affixed to all sides of the interior of the wedge frame. In some embodiments the support structure is positioned about 1⁄2′′ below the top edge of the sides of the support wedge.
As shown in FIGS. 2A-D, the removable rectangular frame 2 is sized and configured to be received within the wedge frame 1 and supported by the support structure 1S of the wedge frame. The support structure of the wedge frame may support perimeter portions of the removable rectangular frame, or the entire base of the removable rectangular frame. A latch mechanism may be incorporated on the underside of the rectangular frame and a corresponding portion of the wedge frame to removably secure the rectangular frame to the wedge frame. Latch mechanisms suitable for securing an infant carrier to its base are known in the art, such as found on the Graco Snap ‘N’ Go car seats, and many of such mechanisms are suitable for use in the present invention. A small notch may be provided near the lower third of the right and left top sides of the removable rectangular frame to secure a car lap belt over the seat when the vehicle is not L.A.T.C.H. equipped. The interior surfaces of the rectangular frame may be covered in expanded polystyrene.
In some embodiments of the described technology the child support surface 2S of the removable rectangular frame is positioned within such frame at an angle of 0-32 degrees, whereby the sum θ of (i) the angle β of the child support surface of the removable rectangular frame relative to the plane of the bottom of the rectangular frame and (ii) the angle α of the support structure of the wedge frame relative to the bottom plane of the wedge frame, when the removable rectangular frame is positioned within the wedge frame, is between 20-40 degrees, or 25-35 degrees, or 28-32 degrees.
As shown in FIGS. 4 and 5, the infant car sear of the described technology further includes adjustable child securing means 3 for securing the infant to the child support surface 2S of the rectangular frame 2. In some embodiments the child securing means includes a plurality of exposed straps 3A extending through apertures in the seat and adjustably secured to the underside of the rectangular base by means of rollers and metal loops, controlled by a push button on a spring release (all as known in the art). The straps may be secured to the rectangular frame by other means used in the art to secure straps or other child securing means in an infant carrier. The exposed length of the straps may be adjusted by means of the adjustable securing means to accommodate different sized infants. The child securing means may be affixed to the removable rectangular frame at several different locations.
In some embodiments the straps may be positioned both vertically and horizontally over the child support surface so that a pair of vertical straps 3V form opposing shoulder straps for the infant, which may be removably and adjustably securable to each other by means of a paperclip chest clasp 3C engaged along the vertical straps. When an infant is positioned within the seat, the chest clasp should be adjusted so that it is positioned at the infant's chest. One or more horizontal straps 3H of the child securing system may form a lap belt, with one or more hip clip systems 3S movably positioned on the horizontal straps, at or about one or both of the hips of an infant when the infant is positioned in the seat. Suitable hip clip systems 3S for the child securing system of the present technology include child-size seat belts, such as rectangular seat belts with a clip on one side, and a receiving means with a pressure button on the other, to receive and secure, and to allow release of, the clip. A crotch belt 3B may be affixed to the center of the lap belt 3H, and be adjustably secured to the underside of the removable rectangular frame.
As shown in FIGS. 1A-E and 2A-C, the removable rectangular frame 2 may further include a carrying support system 4 affixed to opposing sides of the removable rectangular frame. The carrying support system may include a pair of arm support bars rotatably affixed to opposing sides of the rectangular base, using known or hereinafter developed methods and technology. Soft, flame retardant foam grip pads may be affixed around a central segment of the circumferential surface of each horizontal bar.
In embodiments of the disclosed technology the wedge frame, the rectangular frame, the support bars and other rigid components may be constructed from polypropylene plastic or other suitable materials. To increase the strength of the wedge frame without significantly increasing the weight thereof, the portion of the base below the support structure may be hollow or honeycombed, or may have any similar structure that supports the integrity of the wedge frame, but adds limited weight to the product. Exposed edges of both the wedge frame and the removable rectangular frame may be rounded.
The wedge frame of the disclosed technology also includes a latching mechanism (not shown) designed and configured to engage with a vehicle seat belt, allowing and securing the wedge frame to a vehicle; latching mechanisms for this purpose are known in the art.
In embodiments of the disclosed technology the removable rectangular frame may include a fabric covering, lining the interior of the removable rectangular frame and extending over the sides of the rectangular frame. The fabric covering may include flame-retardant padding, covered in fabric. The fabric covering may be removably secured to the removable rectangular frame by means of elastic bands positioned about the fabric covering to allow the bands to be stretched and secured about hooklets secured to and positioned about the exterior of the removable rectangular frame. In some embodiments of the disclosed technology the hooklets are positioned about the exterior of the removable rectangular frame about 1⁄2-3⁄4′′ from the top of the frame.
Components of the disclosed technology may be described independently herein, but molded together as a single unit when manufacturing systems derived from the present invention. Furthermore, the present invention is described by various embodiments of the disclosed technology, which are not intended to limit the invention as claimed in the following claims.
