[0023] like Figure 1 , Figure 2 and Figure 3 , Figure 4As shown, this utility model provides a backrest tilt support frame, including a backrest connecting arm 11, a fixed base 12, and an adjusting arm 13. The upper part of the backrest connecting arm 11 is hinged to a first position 121 of the fixed base 12. One end of the adjusting arm 13 is hinged to a second position 122 of the fixed base 12, with the first position 121 located above the second position 122. The other end of the adjusting arm 13 is connected to the backrest connecting arm 11. The adjusting arm 13 is movable, and the backrest connecting arm 11 rotates around the first position 121. This utility model allows users to easily adjust the backrest angle. Users can operate from the lower part or bottom of the backrest, lifting it to change the tilt degree, thereby increasing the functionality and ergonomics of the product and providing users with a more comfortable bed-sitting experience. Moreover, this utility model has a simple and stable structure.

[0024] Furthermore, in the backrest tilting support frame provided by this utility model, the other end of the adjusting arm 13 is connected to the lower part of the backrest connecting arm 11. The backrest connecting arm 11 is provided with a sliding hole 14. The other end of the adjusting arm 13 is connected to the sliding hole 14 through a pin 15. The adjusting arm 13 or the backrest connecting arm 11 can move, and the other end of the adjusting arm 13 moves in the sliding hole 14 through the pin 15. This utility model realizes the movable connection between the adjusting arm 13 and the backrest connecting arm 11 through the sliding hole 14, so that the backrest connecting arm 11 can be flipped from bottom to top, and the adjusting arm 13 moves with the backrest connecting arm 11, which can be used to limit the range of motion of the backrest connecting arm 11.

[0025] Furthermore, in the backrest tilting support frame provided by this utility model, the sliding hole 14 can be any combination of two or three of the following: a straight strip hole, an arc strip hole, a wavy strip hole, or a combination of straight strip holes, arc strip holes, and wavy strip holes. In this embodiment, a vertical straight strip hole is used. This utility model can even use wavy or other irregularly shaped sliding holes 14 to achieve the effect of fixing the pin 15 at a certain position. Furthermore, in the backrest tilting support frame provided by this utility model, an angle adjuster 16 is provided at the hinge joint between the adjusting arm 13 and the fixed seat 12. One end of the adjusting arm 13 is hinged to the second position 122 of the fixed seat 12 at an adjustable angle via the angle adjuster 16. The angle adjuster 16 can adjust the angle between the adjusting arm 13 and the fixed seat 12, and it can have multiple adjustable positions. The angle adjuster 16 is prior art and will not be described in detail here.

[0026] Furthermore, in the backrest tilting support frame provided by this utility model, the top end of the backrest connecting arm 11 is hinged to the first position 121 of the fixed seat 12, and the other end of the adjusting arm 13 is connected to the sliding hole 14 at the lower part of the backrest connecting arm 11. This makes the product structure simple and compact. Furthermore, in the backrest tilting support frame provided by this utility model, the fixed seat 12 includes a main arm 17 and a fixed angle seat 18. The fixed angle seat 18 is fixed to the main arm 17, and the main arm 17 is connected to the backrest connecting arm 11 and the adjusting arm 13. The main arm 17 mainly provides support during the main angle adjustment, while the fixed angle seat 18 is used to fix the main arm 17 to the headboard or headboard frame. Furthermore, in the backrest tilting support frame provided by this utility model, the main arm 17 is L-shaped, and the top end of the main arm 17 has a short side arm extending towards the side where the backrest connecting arm 11 is located. The first position 121 is located at the tail end of the short side arm. The top end of the adjusting arm 13 is hinged to the bottom end of the main arm 17, and the bottom end of the adjusting arm 13 is connected to the slider of the backrest connecting arm 11. The fixed angle seat 18 is provided with multiple mounting holes (not labeled in the figure), and the fixed angle seat 18 and the main arm 17 are fixedly connected by bolts or pins.

[0027] Furthermore, in the backrest tilting support frame provided by this utility model, the maximum change angle of the backrest connecting arm 11 does not exceed 40°. Preferably, in the backrest tilting support frame provided by this utility model, the maximum change angle of the backrest connecting arm 11 is 28°. This maximum change angle refers to the change angle of the backrest connecting arm 11 from its initial slightly upright state to its tilted maximum state, reflecting the adjustable range of motion of the backrest.

[0028] In other preferred embodiments, the adjusting arm 13 of the backrest tilt support frame provided by this utility model can be a telescopic arm, which is another form of implementation. In this case, the adjusting arm 13 and the backrest connecting arm 11 only need to be hinged, and there is no need to slide them together through an additional slider. The telescopic arm can be an adjustable telescopic arm or a gas spring. By extending and retracting, the backrest connecting arm 11 can be lifted or pulled back so that the headboard can switch between an upright state and a tilted state.

[0029] In summary, this utility model allows users to easily adjust the backrest angle. Users can operate from the lower part or bottom of the backrest to lift it up and change the tilt of the backrest, thereby increasing the functionality and user-friendliness of the product and providing users with a more comfortable sitting experience in bed. Moreover, this utility model has a simple and stable structure.
