[0002] Car seats are an essential component of a car, and their comfort plays a crucial role in the driving and riding experience. Car seat cushions typically contain spring assemblies, which are the core components of the seat system responsible for supporting the human body, cushioning and absorbing shocks, and improving comfort. They absorb the weight of the human body through elastic deformation, reducing the impact force transmitted to the human body from road bumps.

[0003] Existing car seat cushion spring assemblies have poor plasticity and poor longitudinal tensile performance. During use, longitudinal vibrations cannot be effectively buffered, resulting in very limited shock absorption and reduced comfort, failing to meet usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive seat cushion spring assembly to solve the problems mentioned in the background art, such as poor plasticity, poor longitudinal tensile performance, inability to effectively buffer longitudinal vibrations during use, very limited shock absorption effect, reduced comfort, and failure to meet usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car seat cushion spring assembly, comprising four serpentine spring units arranged side-by-side at equal intervals, an L-shaped crossbeam between one end of each of the four serpentine spring units, the L-shaped crossbeam being plastic-coated and connected to the serpentine spring unit, a rectangular crossbeam between the other ends of each of the four serpentine spring units, the rectangular crossbeam being plastic-coated and connected to the serpentine spring unit, and an elastic connecting plate between two adjacent serpentine spring units, the two ends of the elastic connecting plate being plastic-coated and connected to the serpentine spring unit.
