[0037] Embodiment 1:

[0038] Example 1 of the present application discloses an asymmetric sponge cushion. Figure 3The asymmetric sponge cushion comprises a cushion body 1, the material of the cushion body 1 is sponge, and the cushion body 1 is used to be installed on a seat frame produced by stamping and welding processes, so as to ensure the riding comfort of passengers.

[0039] Reference Figure 3 The cushion body 1 is integrally provided with a first side wing 2 and a second side wing 3, and the first side wing 2 and the second side wing 3 are respectively located on both sides of the cushion body 1. The corners of the first side wing 2 and the second side wing 3 are chamfered to reduce the occurrence of the corners of the first side wing 2 or the second side wing 3 being worn.

[0040] Reference Figure 4 The first side wing 2 and the second side wing 3 are both inclined from top to bottom in a direction close to each other, and a cushion groove 101 is formed between the first side wing 2 and the second side wing 3. The cushion groove 101 is located at the top of the cushion body 1 to ensure the comfort of the passenger when sitting on the cushion body 1. The inclination angles of the first side wing 2 and the second side wing 3 are both 20°-40°. Specifically, for the first side wing 2 or the second side wing 3, the inclination angle refers to: the angle between the surface of the first side wing 2 or the second side wing 3 and the horizontal plane.

[0041] Reference Figure 5 The first side wing 2 is provided with an escape groove 201, which is used to escape the safety belt. When the seat cushion body 1 is installed on the seat frame (not shown in the figure), the second side wing 3 is covered on the seat frame. When two seat cushion bodies 1 are arranged side by side on the seat frame of the bus, the second side wings 3 of the two adjacent seat cushion bodies 1 are close to each other and cover the seat frame together, making it difficult for passengers to see or touch the seat frame, thereby ensuring the aesthetics on the one hand and reducing the occurrence of passengers' hands being scratched by the burrs of the seat frame on the other hand.

[0042] The implementation principle of an asymmetric sponge seat cushion in Example 1 of the present application is as follows: through an asymmetric designed first side wing 2 and a second side wing 3, while ensuring the normal use of the safety belt, the seat frame is covered by the second side wing 3, so that it is not easy to form a gap when the two sponge seat cushions are arranged side by side, thereby reducing the possibility of scratches on the passengers' hands caused by the seat frame with burrs.

[0043] Embodiment 2:

[0044] Embodiment 2 of the present application discloses an asymmetric sponge cushion, which is mainly different from Embodiment 1 in that the specific configuration of the second side wing 3 is different.
