Drawings

The following describes the present invention in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. The lightweight automobile rear seat cushion framework is used for bearing foaming materials and is arranged on a seat frame, and comprises a framework body, wherein the framework body comprises a U-shaped outer steel wire 1, a U-shaped inner steel wire 2, an inverted U-shaped steel wire 3, a first cross brace steel wire 4, a second cross brace steel wire 5 and a hanging steel wire 6, the U-shaped inner steel wire 2 is arranged inside the U-shaped outer steel wire 1, the upper ends of the U-shaped inner steel wire 2 and the U-shaped outer steel wire 1 are welded with each other, a first bending section 7 and a second bending section 8 which are upwards bulged are respectively arranged on the transverse steel wires of the U-shaped inner steel wire 2 and the U-shaped outer steel wire 1, the first cross brace steel wire 4 is flush with the first bending section 7 and the second bending section 8, the two ends of the first cross brace steel wire 4 are welded to the lower parts of the longitudinal steel wires at the two sides of the U-shaped outer steel wire 1 downwards, the hanging steel wires 6 are bilaterally symmetrical two groups, and the hanging steel wires 6 are formed by folding back, the reverse end of the hanging steel wire 6 forms a hook 9 and is hooked on the first cross brace steel wire 4, and the other end of the hanging steel wire 6 is respectively welded on the U-shaped inner steel wire 2 and the U-shaped outer steel wire 1; the lower ends of the inverted U-shaped steel wires 3 are respectively welded to the upper parts of longitudinal steel wires on two sides of the U-shaped inner steel wire 2 and the U-shaped outer steel wire 1, third bending sections 10 which are sunken inwards are arranged on the longitudinal steel wires on two sides of the inverted U-shaped steel wires 3, the upper ends of the longitudinal steel wires on two sides of the inverted U-shaped steel wires 3 are bent upwards, and the transverse steel wires of the corresponding inverted U-shaped steel wires 3 are flush with the first cross brace steel wires 4; the both ends of second stull steel wire 5 are equipped with down kinking section 11, and kinking section 11 is crooked towards the horizontal steel wire arc of the U-shaped steel wire 3 down, and the lower extreme of kinking section 11 is equipped with inflection section 12 down, and the outer end of inflection section 12 welds on falling U-shaped steel wire 3.
