Each of the seat sides 88 is engaged at a rear edge to an edge portion of seat back 86. At a medial portion of its lower edge, each of the seat sides 88 is engaged to seat bottom 84. Such an engagement, which terminates short of the front edge of seat bottom 84 and short of the front edge of seat side 88, permits the front portion of seat side 88, having pocket 104, to be lifted up such that pocket 104 can catch the top of hub post or extension 96 such that hub post or extension 96 can slide into pocket 104. It should be noted that each of the seat sides 88, when folding child booster seat 10 is in the open position, is relatively fully extended and resides in a plane generally at a right angle to seat bottom 84 such that seat sides 88 extend in generally a vertical plane. Each of seat sides 88 further includes a piece of mesh stitched to the outside of the right side seat side 88 so as to form a pocket 106 therewith.
Seat portion 14 further includes a removable washable cover 108. Cover 108 is generally a rectangular piece of fabric, such as nylon. A front edge portion of cover 108 is engaged by a hook and loop engagement 109 such as Velcro® or other quick connect, to a front edge portion of seat bottom 84 such that cover 108 is removable and washable separately from the seat bottom 84, seat back 86 and seat sides 88. A rear end portion of cover 108 includes a pocket 110 to removable receive an upper edge portion of seat back 86 drawn taut by virtue of the back seat support members 18 being drawn fully apart by the opening of the pivoting support member arrangement 16. Such pocket 110 also indirectly receives upper end portions of the back seat support members 18. Cover 108 has sufficient length to lay upon the upper face of seat bottom 84 and to lay against the front face of seat back 86.
It should be noted that the perimeter of each of seat bottom 84, seat back 86, seat sides 88, and cover 108 includes a reinforced fabric edge, with the exception of the lower edge of seat back 86 that meets with and engages the seat bottom 84.
Seat portion 14 further includes a child restraint arrangement 112. Restraint arrangement 112 includes a pair of first straps 114 extending from the seat back 86 and a central strap 116 extending from seat bottom 84. Each of straps 114 includes a respective buckle portion 117 that couples with buckle portion 118 of central strap 116. Each of straps 114 includes a buckle portion 120 that provides for length adjustment of its respective strap 114.
First fastener 20 includes a pair of straps having buckle portions or quick connect portions at their distal ends for coupling with each other to anchor the folding child booster seat 10 to a seat back 122 of chair 34.
Second fastener 22 includes a pair of straps having buckle portions or quick connect portions at their distal ends for coupling with each other to anchor the folding child booster seat 10 to a seat bottom 78 of chair 34.
As shown in FIG. 6, a kit for the folding child booster seat 10 can include a bag 124 for receiving the folding child booster seat 10 in a closed position.
In operation, the folding child booster seat 10 is withdrawn from bag 124. Then a hand may be placed on the seat bottom 84 (or cover 108 on the seat bottom 84) to open, in a scissors like fashion, the pivoting support member arrangement 16 until stops 66 confront rear seat hubs 27. Then the folding child booster seat 10 may be placed on a seat bottom 84 of chair 34. Then flaps 100 are engaged to their respective seat back support members 18. Then fasteners 20 and 22 are respectively engaged to the seat back 122 and seat bottom 84 of chair 34. Then a child may be placed in the seat portion 14 and buckled in with restrain arrangement 112. After dinner, the child can be removed from the seat portion 14, whereupon fasteners 20 and 22 can be disengaged from chair 34. Then flaps 100 are disengaged from their respective seat back support members 18 so as to permit the seat back support members 18 to be drawn inwardly toward each other. Then opposing portions of the pivoting support member arrangement 16 can be pushed together so as to collapse, in a scissors like fashion, the pivoting support member arrangement 16, which operation folds the seat portion 14. If desired, the seat sides 88 can be tucked inwardly, the flaps 100 can be tucked inwardly, and the upper end of cover 108 having pocket 110 can be tucked downwardly such that seat sides 88, flaps 100, upper end of cover 108 and the seat portion 14 as a whole can generally be disposed within four posts defined by seat back support members 18 and hub extensions 96 as the frame portion 12 collapses. Such four posts are drawn together as the frame portion 12 collapses and such a drawing in also draws in the seat portion 14 such that folding child booster seat 10 is a compact structure for insertion into bag 124.
