The bottom plate 401, the left side stop 402 and the right side stop 403 are integrally formed, and the intersection of the bottom plate 401 and the left side stop 402, as well as the intersection of the bottom plate 401 and the right side stop 403 are smoothly transitioned to ensure the overall strength of the seat basin body 4. The bottom plate 401 includes a transverse tube installation area 4011 and an anti-submergence transverse rib area 4012. The transverse tube installation area 4011 is located at the front end of the bottom plate 401, and the anti-submergence transverse rib area 4012 is located at the rear side of the transverse tube installation area 4011.

The above dimensions have been verified by theoretical calculation and simulation analysis, and the dummy does not dive during a frontal collision, and its H-point displacement is optimal under this dimension. In addition, a row of raised longitudinal rib structures 4013 are evenly arranged along the left and right directions on the anti-diving transverse rib area 4012, which not only improves the rigidity of the seat basin body 4, but also plays a certain role in anti-diving.

[0030] This embodiment provides a new seat basin tilt adjustment structure. Figure 3 and Figure 4As shown, it includes a transverse tube 1, a left side plate 2, a right side plate 3, a driving mechanism 9 and a seat basin body 4 provided in Example 1.

The front end of the left side plate 2 is hingedly mounted with a left front link bracket 6 and a motor mounting bracket 8 through a first step bolt 10, a first bushing 11 and a second bushing 12. The left end of the transverse tube 1 is welded to the motor mounting bracket 8. One end of the left front link bracket 6 is hinged to one end of the motor mounting bracket 8, and the other end of the left front link bracket 6 is hinged to the seat support structure. The front end of the right side plate 3 is hingedly mounted with the right front link bracket 5 and the right front tilt bracket 16 through the second step bolt 19, the third bushing 17 and the fourth bushing 18, and the right end of the cross tube 1 is welded to the right front tilt bracket 16.

When adjusting the inclination angle, the motor drives the nut to rotate, and then drives the screw to move forward and backward. When the screw moves forward and backward, it drives the cross tube 1 to rotate through the screw connection bracket 7. When the cross tube 1 rotates, it drives the right front tilt bracket 16 and the motor mounting bracket 8 to rotate, and then drives the seat basin body 4, the left panel 2, and the right panel 3 to achieve angle adjustment.

[0031] The working principle of the utility model is: by rationally designing the size of the basin body 4, such as Figure 3 and Figure 5As shown, the transverse tube installation area 4011 at the front end of the seat basin body 4 can be located in a reasonable submersible tube arrangement area 23, and the transverse tube 1 is installed in a reasonable submersible tube arrangement area 23, which can prevent collision diving. The seat basin body 4 is provided with an anti-submersible transverse rib area 4012. The structure and size of the anti-submersible transverse rib area 4012 are verified by theoretical calculation and simulation analysis. The dummy does not dive during a front collision, and its H-point displacement is in an optimal state under this size. In addition, a row of raised longitudinal rib structures 4013 are evenly arranged along the left and right directions on the anti-submersible transverse rib area 4012, which not only improves the rigidity of the seat basin body 4, but also plays a certain role in anti-submersible. Therefore, although the utility model is only provided with one transverse tube 1, by reasonably arranging the installation position of the transverse tube 1 and reasonably designing the structure and size of the seat basin body 4, the goals of energy saving, environmental protection, simplified structure and lightweight are achieved without changing the performance of the car seat frame, saving material costs and assembly costs.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
