Description

Technical Field

[0001] The utility model relates to the technical field of back or cushion technology, in particular to an adaptive pneumatic lumbar support assembly. Background Art

[0002] An adaptive pneumatic lumbar support assembly is a lumbar support system designed to provide support and comfort. It usually consists of a pneumatic lumbar support, an adjustable support structure, and a sensor that can sense the user's posture and activity and adjust the position and pressure of the lumbar support as needed to provide optimal support and comfort. This system is often used in car seats, office chairs, and other occasions where long periods of sitting are required to reduce lumbar pressure and improve sitting comfort.

[0003] After searching, a pneumatic lumbar support assembly with the announcement number CN206231266U is found, which relates to the technical field of the backrest or cushion of the car. The lumbar support assembly includes a backrest frame, a backboard, a limiting rod, an airbag and a buckle. The limiting rod is fixed to the backrest frame, and a U-shaped clamping part is provided on the limiting rod. The buckle is fixed to the backboard. The buckle is clamped into the U-shaped clamping part and is limited to the left and right through the U-shaped clamping part. The airbag is clamped to the backboard, and the backboard is located as a whole in the frame surrounded by the backrest frame. The position of the buckle corresponds to the position of the U-shaped slot on the positioning rod, and the buckle can be quickly and conveniently clamped into the U-shaped slot. The U-shaped slot can realize the positioning of the buckle to prevent it from shaking left and right, thereby preventing the backboard provided with the airbag from shaking during use, making it more stable to use.

[0004] The above patent mentioned that "the backboard with the airbag is prevented from shaking during use", but in actual use, although the backboard can be prevented from shaking during use, the pipeline cannot be sealed and docked. If the lumbar support assembly cannot effectively seal the docking pipeline, gas or liquid leakage may occur. This may affect the performance and efficiency of the system, and may even cause system failure or unstable operation. Therefore, in response to the above problems, an adaptive pneumatic lumbar support assembly is proposed. Utility Model Content
