The shape of the fixed steel wire 104 is inverted U-shape and corresponds to the shape of the first limiting steel wire group 101, the second limiting steel wire group 102 and the third limiting steel wire group 103 after welding. The fixed steel wire 104 is fixedly connected to the first limiting steel wire group 101, the second limiting steel wire group 102 and the third limiting steel wire group 103. The first limiting steel wire group 101 and the third limiting steel wire group 103 are located on both sides of the second limiting steel wire group 102.

[0033] The foam assembly 3 includes: a foam support block 301 arranged on the front seat back frame assembly 1, and an avoidance groove 302 is opened on the foam support block 301. The shape of the avoidance groove 302 corresponds to the shape of the inverted U-shaped avoidance frame.

[0034] The face guard assembly 2 includes: a first panel 201, a second panel 202, a third panel 203, a fourth panel 204, a fifth panel 205, a sixth panel 206, a seventh panel 207, an eighth panel 208, and a non-woven fabric tightening strip 209. The first panel 201 is laid on the inner surface of the avoidance groove 302, the second panel 202 is laid on the side of the avoidance groove 302, the third panel 203 and the fourth panel 204 are symmetrically laid on both sides of the outside of the avoidance groove 302 of the foam support block 301, and the fifth panel 205 is laid above the avoidance groove 302 of the foam support block 301.
