Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a novel seat cushion foam positioning structure. Background Technology

[0002] The conventional design of seat cushion foam uses the outer contour to match the seat frame for positioning. Considering that the foam is polyurethane foam with a hardness value of 10-15KPA, although this hardness value can ensure riding comfort, it is prone to deformation. When there are high precision requirements for the matching structure, the amount of deformation of the foam under the pressure of the cover will be greater than 5mm, which cannot meet the precision requirements and affects the appearance. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a new type of seat cushion foam positioning structure to overcome the shortcomings of inaccurate positioning.

[0004] This utility model provides a novel seat cushion foam positioning structure, including a seat cushion foam. The improvement is that it also includes a rigid molded foam and a snap-fit ​​protrusion fixed to the seat frame. The hardness value of the seat cushion foam is 10-15 kPa, and the hardness value of the rigid molded foam is greater than 200 kPa. The rigid molded foam is located at the connection position between the seat cushion foam and the seat frame. The snap-fit ​​protrusion is welded or bolted to the seat frame. The rigid molded foam has a positioning groove corresponding to the position of the snap-fit ​​protrusion. The rigid molded foam is snapped onto the snap-fit ​​protrusion on the seat frame through the positioning groove. The seat cushion foam is fixed to the seat frame through the rigid molded foam.

[0005] As a preferred embodiment of this invention, the rigid molded foam is foamed at the bottom edge of the seat cushion foam.

[0006] The beneficial effects of this utility model are as follows:

[0007] 1. This utility model uses rigid molded foam with a hardness value greater than 200kpa and foam integrally formed. The rigid molded foam works in conjunction with the seat frame to fix the position, so as to achieve accurate positioning of the seat foam and improve the appearance and abnormal noise problems.

[0008] 2. This utility model has the advantages of simple and reliable structure and strong stability. Attached Figure Description

[0014] The attached reference numerals include: 1. seat cushion foam; 2. rigid molded foam; 3. seat frame; 4. snap-fit ​​protrusion. Detailed Implementation

[0015] See Figure 1-4 As shown, this embodiment provides a novel seat cushion foam positioning structure, including a seat cushion foam 1, a rigid molded foam 2, and a snap-fit ​​protrusion 4 fixed to a seat frame 3. The seat cushion foam 1 has a hardness value of 10-15 kPa, and the rigid molded foam 2 has a hardness value greater than 200 kPa. The rigid molded foam 2 is located at the connection position between the seat cushion foam 1 and the seat frame 3. The snap-fit ​​protrusion 4 is welded to the seat frame 3. A positioning groove is formed on the rigid molded foam 2 corresponding to the position of the snap-fit ​​protrusion 4. The rigid molded foam 2 is snapped onto the snap-fit ​​protrusion 4 on the seat frame 3 through the positioning groove, and the seat cushion foam 1 is fixed to the seat frame through the rigid molded foam 2. The rigid molded foam 2 is foamed and molded at the bottom edge of the seat cushion foam 1.

[0016] Working principle: Rigid molded foam 2 with a hardness value greater than 200kpa and seat cushion foam 1 are produced together. The rigid molded foam 2 works in conjunction with the seat frame 3 to fix the position, so as to achieve precise positioning of the seat foam and improve the appearance and noise problems.

[0017] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
