Example Embodiment

[0047] Example 1: Such as Figures 1 to 7 As shown, a rotary adjustment of a baby seat, including the seat 1 and the backrest group 2. The backrest group 2 extends backward from the rear end of the seat 1, and the backrest group 2 forms a carrier region, the backrest group 2 including a support frame 3 and a variable extended height backrest support. 4. The support frame 3 is disposed at the rear end of the seat 1, the support frame 3 comprising a lower shaft tube 31 and an upper shaft tube 32, and the lower shaft tube 31 extends from the seat 1 rear endward and upward. The upper shaft tube 32 is pivotally coupled to the upper end of the lower shaft tube 31, and the backrest support portion 4 can be provided with the lower shaft tube 31, and one side of the backrest support portion 4 and the The upper shaft tube 32 is connected, and when the upper shaft pipe 32 is pivoted with respect to the lower shaft pipe 31, the backrest support portion 4 can be rotated against the lower shaft ...

Example Embodiment

[0058] Example 2: Figure 8 to 10 As shown, the present embodiment differs from the embodiment that the top stroe 5 is connected to the backrest support portion 4, and when the upper shaft tube 32 rotates to change the angle of the angle with respect to the lower shaft pipe 31 When the top stroe 5 can move with the backrest support portion 4. The top stroe 5 can move with the back support, which allows the top strut 5 to hit the child in the most suitable location.

[0059] Specifically, for the convenience of the top archery, the top beam 5 is slid to be coupled to the support frame 3, and the top trapection 5 is pivoted between the backrest support portion 4. The brake rod 7 can be rotated with the angular angle of the angle, which in turn urges the top strip 5 to slide along the support frame 3. In order to actically move the top arbitrarier 5, the link rod 7 is pivoted between the top trapez 5 and the lower back plate 41. Simple structure, good connection effect.

Example Embodiment

[0060] Example 3: Figure 11 with Figure 12 As shown, the present embodiment differs from the first example, the backrest support portion 4 is a resilient software that rotates to change the stretch height with the upper shaft pipe 32. With elastic software, the height of the backrest support can be achieved, and the structure is simple and easy to use.

Abstract

The invention provides a baby seat capable of rotatably adjusting the height of a backrest. The baby seat comprises a seat and a backrest group, the backrest group extends backwards and upwards from the rear end of the seat, the backrest group and the seat form a bearing area, and the backrest group comprises a support frame and a backrest support part with variable extension height. The support frame is arranged at the rear end of the seat and comprises a lower shaft connecting pipe and an upper shaft connecting pipe, the lower shaft connecting pipe extends backwards and upwards from the rear end of the seat, and the upper shaft connecting pipe is pivoted to the upper end of the lower shaft connecting pipe; and the backrest support part and the lower shaft connecting pipe can form an included angle, one side of the backrest support part is connected with the upper shaft connecting pipe, and when the upper shaft connecting pipe pivots relative to the lower shaft connecting pipe, the backrest support part can be driven to rotate relative to the lower shaft connecting pipe so as to change the included angle, and meanwhile, the height change of the backrest support part is linked. The backrest support part is driven by the rotation angle difference between the lower shaft connecting pipe and the upper shaft connecting pipe to change the extension height, the effect of adjusting the height of the backrest is achieved, and operation is easy.

Description

【Technical field】 [0001] The present application relates to the field of baby products, in particular to a baby seat with a rotating backrest height adjustment. 【Background technique】 [0002] Infant seats are a very common nurturing product and some existing baby seat backs do not allow the height adjustment of the backrest as the child grows, and if the backrest is too long, the backrest does not provide enough coverage for smaller children If the backrest is too short, it will be uncomfortable and inconvenient for older children to use. 【Content of invention】 [0003] In order to adjust the height of the backrest of the baby seat conveniently, the present application provides a baby seat with a rotationally adjustable backrest. [0004] The application is realized by the following technical solutions: [0005] Infant seat with swivel backrest height adjustment, including: [0006] seat; [0007] a backrest set extending backward and upward from the rear end of the s...
