[0017] This invention provides a growth-adjustable child seat, such as... Figures 1-5As shown, it includes a seat 1 and a backrest 2 mounted on it. Armrests 3 are provided on both sides of the backrest 2. Four support legs 4 are provided at the bottom of the seat 1. The lateral length of the seat 1 and the backrest 2 is adjustable, the height of the armrests 3 is adjustable, and the length of the support legs 4 is adjustable.
[0018] like Figure 1 As shown, the seat 1 includes two sets of supports 11. Each support 11 has several insert rods 12 arranged longitudinally at equal intervals. The width of the slot 13 between two adjacent insert rods 12 is slightly larger than the insert rod 12. Figure 5 As shown, the insertion rods 12 on the two sets of brackets 11 can be inserted into each other's slots 13. The bottom of the bracket 11 is provided with a support plate for supporting the insertion rods 12. The bottom of the support plate of the bracket 11 is threaded with a fixing bolt 10 for locking the insertion rods 12.
[0019] The two brackets 11 on both sides can be adjusted laterally to extend the lateral length. During adjustment, the insertion rods 12 on the two brackets 11 slide in the slots 13 on the opposite brackets 11.
[0020] Because a space will appear between the ends of the insertion rod 12 and the slot 13 when the lateral length of the seat plate 1 is adjusted, in order to fill this space, such as Figure 2 and Figure 5 As shown, the seat 1 also includes a vertical plate 14, several airbag strips 15, and springs 18. The vertical plate 14 is vertically arranged at the bottom of the bracket 11. When the airbag strips 15 are fully inflated, their cross-sectional dimensions are the same as those of the insert rods 12. The vertical plate 14 has a receiving cavity 16 for accommodating the several airbag strips 15. A guide block 17 is vertically slidably fitted inside the receiving cavity 16. The guide block 17 is connected to the bottom of the receiving cavity 16 through the springs 18. One end of each airbag strip 15 is connected to the guide block 17, and the other end is connected to the opposite insert rods 12.
[0021] When the insertion rod 12 pulls the airbag strip 15 outward, the airbag strip 15 will be pulled out of the receiving cavity 16. The airbag strip 15 is used to fill the space between the insertion rod 12 and the slot 13, thereby improving the sitting comfort.
[0022] When the airbag strip 15 is pulled out of the receiving cavity 16, it will stretch the spring 18. When the insertion rod 12 is adjusted in the opposite direction, the airbag strip 15 will be pulled back into the receiving cavity 16 by the spring 18.
[0023] An inflation port 19 is provided on the outer side of the upright plate 14. The inflation port 19 is connected to the airbag strip 15 through a hose 20. The hose 20 is relatively long and is located at the bottom of the guide block 17. As the guide block 17 rises, the hose 20 has sufficient slack to rise with it, so as not to affect the inflation.
[0024] like Figure 1As shown, the backrest 2 includes two uprights 21, several sets of crossbar sleeves 22, and telescopic crossbars 23. The two uprights 21 are vertically mounted on two supports 11, and the telescopic crossbars 23 are telescopically mounted on the crossbar sleeves 22. The ends of the crossbar sleeves 22 and the telescopic crossbars 23 are respectively connected to the two uprights 21. When the width of the two supports 11 is adjusted laterally, the two uprights 21 will move accordingly, and the telescopic crossbars 23 can slide telescopically on the crossbar sleeves 22.
[0025] like Figure 1 and Figure 4 As shown, the handrail 3 includes a handrail plate 31. A vertical groove 32 is formed on the upright 21, and a slider 33 connected to the handrail plate 31 is slidably fitted within the groove 32. Positioning holes 34 are formed vertically at equal intervals on the back of the upright 21, passing through the groove 32. A fixing bolt 35 corresponding to the slider 33 is threaded onto the positioning hole 34. A screw hole matching the fixing bolt 35 is formed on the back of the slider 33. After the height of the handrail 3 is adjusted, the handrail plate 31 is locked by passing the fixing bolt 35 through the corresponding positioning hole 34 and locking it in the screw hole of the slider 33.
[0026] like Figure 1 As shown, the support leg 4 includes a vertical rod sleeve 41 and a telescopic column 42 telescopically disposed at the bottom of the vertical rod sleeve 41. The vertical rod sleeve 41 is vertically fixed to the bottom of the upright plate 14. The telescopic column 42 is provided with vertically spaced fixing holes 43. The vertical rod sleeve 41 is connected by a horizontal thread to a fixing bolt 44 that matches the fixing hole 43.
[0027] When the length of the support leg 4 needs to be adjusted, first loosen the fixing bolt 3 44, then extend and retract the telescopic column 42 until the appropriate height is reached, and then screw the fixing bolt 3 44 into the corresponding fixing hole 43. Locking is now complete.
