Embodiment

[0012] An airbag folding method of a driver's airbag is characterized in that it is first folded along the X-axis of the dotted line in the figure, and then folded along the Y-axis of the dotted line in the figure. The steps are:

[0013] Step 1. Fold in the X-axis direction:

[0014] figure 1 It is a top view of the airbag 5 of the driver's airbag, and the folding line 1 below the X-axis indicates the folding position of the airbag 5,

[0015] a) first fold the air bag 5 upwards along the folding line 1 to obtain the following figure 2 the shape shown;

[0016] b) Next, fold the upper folded part of the air bag 5 down along the fold line 2 to obtain the following image 3 the shape shown;

[0017] c) Fold the folded part of the air bag 5 upward along the folding line 1 again to obtain the following Figure 4 the shape shown;

[0018] d) Finally, fold the upper folded part of the air bag 5 down along the fold line 2 to obtain the following Figure 5 the shape shown;

Abstract

The invention relates to an airbag folding method for driver airbag. The method of the invention is characterized in that the airbag is folded symmetrically along X axis direction and then is non-symmetrically folded along Y axis. As for the U type or n type tearing line form cover, the folding method can ensure the cover tearing line breaks along the designed path with a better expansion effect of airbag.

Description

technical field [0001] The invention relates to an air bag folding method of a driver's air bag, which can be used for folding an air bag decorated with a '∪' or '∪' tear line and belongs to the technical field of automobile air bags. Background technique [0002] At present, the stacking method of the air bag of the driver's airbag usually adopts a double symmetrical structure in the X direction and the Y direction. This folding method is suitable for the air bag whose 'H'-shaped tear line of the steering wheel trim is in the middle of the trim. For the cover in the form of '∪' or '∩' tear line, the double symmetrical air bag folding method will affect the splitting of the tear line and the unfolding effect of the air bag. Contents of the invention [0003] The purpose of the present invention is to provide a kind of airbag folding method suitable for the driver's airbag of '∪' type or '∪' type tear line form decorative cover. [0004] In order to achieve the above objec...
