[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a foldable front seat frame for an automobile, comprising a backrest frame 14, a seat cushion frame and an adjustment mechanism, wherein the adjustment mechanism is used to enable the backrest frame 14 and the seat cushion frame to be linked and folded forward at the same time.

[0027] The adjustment mechanism includes an unlocking handle 1, an unlocking rod 2, an angle adjuster 3, a cable 4, a cable connecting rod 5, a front seat connecting rod 6, a reinforced lock hook connecting spring 7, a reinforced lock hook 8, a reinforced lock rod 9, a cushion connecting screw 10, a seat foot 11, a seat foot support 12 and a seat foot support connecting screw 13. Among them, the unlocking handle 1 can be movably connected to the front end of the unlocking rod 2, the end of the unlocking rod 2 is connected to the axis position of the angle adjuster 3, one end of the cable 4 is fixed to the middle position of the unlocking rod 2, and the other end is fixed to the front end of the cable connecting rod 5. The end of the cable connecting rod 5 is welded to the front seat connecting rod 6, and the reinforced lock hook 8 is welded to the front seat connecting rod 6. One end of the reinforced lock hook connecting spring 7 is hung on the reinforced lock hook 8, and the other end is hung on the seat cushion connecting screw 10. The reinforced lock rod 9 is fixed on the seat foot support 12. One end of the seat foot 11 is connected to the crossbeam 15 of the seat cushion frame through the seat cushion connecting screw 10, and the other end of the seat foot 11 is connected to the seat foot support 12 through the seat cushion connecting screw 13.

[0028] When the seat is in the sitting state, the reinforced lock hook 8 is in the state of hooking the reinforced lock rod 9, and is connected to the seat cushion connecting screw 10 by the reinforced lock hook connecting spring 7 applying tension, so as to maintain the seat sitting posture. At the same time, the seat position can be maintained in the event of a collision, thereby improving safety performance and reducing passenger injury value.

[0029] When the seat needs to be folded forward to release space, the unlocking handle 1 is pulled, which acts on the recliner 3 through the unlocking rod 2 to fold the seat back 14 forward; at the same time, the unlocking rod 2 rotates upward to drive the cable 4 to pull the zipper connecting rod 5, so that the reinforced lock hook 8 rotates and unlocks; a force is applied forward and downward manually to make the seat foot 11 rotate forward and downward around the seat foot support connecting screw 13, driving the seat to fold forward and downward.

[0030] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the seat frame also includes a base 16, an auxiliary connecting plate 17, a slide rail 18, a strip slider 19 and an armrest 21. The strip slider 19 is installed on the slide rail 18, and the strip slider 19 can slide on the slide rail 18. The seat foot support 12 and the base 16 are respectively installed at both ends of the strip slider 19. The base 16 is connected to the backrest frame 14 through the auxiliary connecting plate 17, and the end of the crossbeam 15 is connected to the slide groove 22 of the armrest 21 and can slide in the slide groove 22. The armrest 21 is installed on the auxiliary connecting plate 17. The ends of the two strip sliders 19 are connected to push-pull rods 20, and the synchronization rod 23 is connected between the two seat feet 11. The recliner 3 is installed at the upper position of the base 16, and the two recliners 3 on both sides of the seat frame are connected by a rotating shaft 3-1.
