Definitions

• the present invention relates to a booster seat for children with a folding tray and a supporting rod therefor.
• booster seats for children allow children to sit on normal chairs at a table, in case a child is too small to use a normal adult chair but has grown enough to find the high chair too narrow and uncomfortable, or when the use of the high chair is not practical. Furthermore, most booster seats have a tray as a replacement for the table top. Certain booster seats have a rod engaged in the center of the bottom surface of the tray to be situated between the child’s legs as he/she sits.
• Booster seats are folded to a more compact closed form for storage when not in use and for easier transport.
• the booster seat can be only folded to the closed position after removing the tray.
• the tray with the rod In booster seats of the prior art, in order to fold, store and carry the booster seat, the tray with the rod must be first separated from the frame, the latter must be moved to a closed position by folding down the backrest onto the seat portion and collapsing the legs. Since the rod overhangs the tray, the backrest cannot be folded down onto the seat without first removing the tray with the rod. This requires an additional operation when folding and requires in certain cases two separate parts to be carried, the frame with the backrest and the seat, and the tray with the rod. Therefore, the booster seat 1 in the closed configuration is not very practical to carry and store.
• the frame is redeployed for the tray and the rod to be reconnected to the booster seat.
