Technical Field

[0001] This utility model relates to the field of automotive seat back technology, specifically to a lumbar support structure for automotive seat backs. Background Technology

[0002] Car seats are installed in cars to provide support for drivers and passengers. The back of the car seat provides support for the occupants. To reduce the strain on the lower back caused by long periods of sitting and driving, a support structure is usually installed in the lumbar region to support the lower back.

[0003] Patent document CN220447715U discloses a lumbar support structure for a car seat backrest. It states that "this utility model uses a rotating torsion block, which causes a screw to rotate during the rotation of the torsion block. During the rotation of the screw, the mounting rod and connecting rod move forward or backward, thereby moving the support frame back and forth. This adjusts the support device's support force on the user's lumbar region, adapting it to different environments and the needs of different users, thus improving the practicality of the support structure."

[0004] However, the support structure described in the aforementioned published documents mainly considers how to adjust the support force when the support structure supports the waist, but the support structure has limited functionality in use and cannot massage the user's waist as needed.

[0005] In view of this, it is necessary to develop a lumbar support structure for car seat backrests that can massage the user's lower back according to the user's needs. Utility Model Content

[0006] The purpose of this utility model is to provide a lumbar support structure for a car seat back, so as to solve the technical problem mentioned in the background art that the support structure has limited functionality and cannot massage the user's waist as needed.
