Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The embodiment of the present application provides a seat mounting bracket and a car seat connected to a car restraint system, which can solve the problem that the seat belt buckle fixing structure in the related art adopts a split design of a seat belt buckle bracket and a link bracket, which is insufficient in terms of space utilization and assembly difficulty.

[0045] See also Figure 1 and Figure 2 As shown, a first aspect of an embodiment of the present application provides a seat mounting bracket connected to a vehicle restraint system, the seat mounting bracket 100 comprising:

The height difference between the guide rail connecting section 11a and the avoidance protrusion section 11b is 16 mm, which can effectively avoid other components on the seat rail 205 and reduce the contact area with the seat rail 205. At the same time, it can also effectively increase the tensile strength of the bracket body 10.

[0057] In some alternative embodiments: See Figures 3 to 7 As shown, an embodiment of the present application provides a seat mounting bracket connected to a vehicle restraint system, wherein the first threaded hole 21 on the link bracket mounting plate 20 of the seat mounting bracket 100 is extracted into an M9 threaded hole by a tapping process, the tapping height of the first threaded hole 21 is 3 mm, and the thread depth in the hole is 5 mm.
