Specific embodiment
The present invention is described further in conjunction with accompanying drawing.
The present invention is a kind of side curtain airbag guiding trestle, including main body, mounting surface and spigot surface.The two ends difference of main body 1-6Mounting surface 1-1 is extended laterally to, spigot surface 1-9 is provided with front side of main body 1-6, main body 1-6 is by tree-like screw 4 and side curtain airbag 5Connection, mounting surface 1-1 is fixed and is formed pre- arrangement by bolt 8, anti-rotation folder 7 and locking packing ring 6 with side curtain airbag 5, prepackage groupPart presss from both sides 7 and is arranged on vehicle body sheet metal 2 across after ventilation duct 3 by bolt 8 and anti-rotation.
Main body 1-6 is sequentially connected the master of the folding surface structure for constituting, left side and right side by three sections of main surface 1-5 from left to rightHonorable 1-5 is connected with mounting surface 1-1 respectively.Tree-like screw mounting hole 1-10 is respectively equipped with the main surface 1-5 on left side and right side,The tree-like screw mounting hole 1-10 on right side is located between waling 1-11.The length of middle main surface 1-5 and ventilation duct 3Length matching.
In order to increase the intensity of guiding trestle 1, it is to avoid it is received the impact of side curtain airbag 5 and deforms, and main body 1-6 is provided with fiveWaling 1-11, wherein three are located on middle main surface 1-5, two are located on the main surface 1-5 on right side, and longitudinal direction addsStrong muscle 1-11 extends to spigot surface 1-9.Two cross reinforcing 1-12 are provided with the bending structure of main body 1-6.
