[0026] As Figure 1 、 Figure 2 and Figure 3 shown, an embodiment of the present invention provides a foldable front-row seat frame for an automobile, including a backrest frame 14, a seat cushion frame, and an adjustment mechanism. The adjustment mechanism is used to link the backrest frame 14 and the seat cushion frame to fold flat forward simultaneously.

[0027] The adjustment mechanism includes an unlocking handle 1, an unlocking rod 2, a recliner 3, a cable 4, a cable connecting rod 5, a front seat link 6, a reinforcement lock hook connecting spring 7, a reinforcement lock hook 8, a reinforcement lock rod 9, a seat cushion connecting screw 10, a seat leg 11, a seat leg support 12, and a seat leg support connecting screw 13. Among them, the unlocking handle 1 is 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 recliner 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 link 6, and at the same time, the reinforcement lock hook 8 is welded to the front seat link 6. One end of the reinforcement lock hook connecting spring 7 is hung on the reinforcement lock hook 8, and the other end is hung on the seat cushion connecting screw 10. The reinforcement lock rod 9 is fixed to the seat leg support 12. One end of the seat leg 11 is connected to the cross beam 15 of the seat cushion frame through the seat cushion connecting screw 10, and the other end of the seat leg 11 is connected to the seat leg support 12 through the seat leg support connecting screw 13.

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

[0029] When the seat needs to be folded forward to release space, pull the unlocking handle 1, act on the recliner 3 through the unlocking rod 2 to make the backrest frame 14 fold flat forward; at the same time, the unlocking rod 2 rotates upward to drive the cable 4 to pull the cable connecting rod 5, so that the reinforcement lock hook 8 rotates to unlock; manually apply a forward and downward force to make the seat leg 11 rotate forward and downward around the seat leg support connecting screw 13, driving the seat to fold forward and downward to be flat.

[0030] As 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 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. 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.
