Manual folding method and folding device for air bag

Abstract

The invention discloses a manual folding method for an air bag, which comprises the following steps of: longitudinally folding the horizontal spread air bag at one time; overlapping the left air bag twice along the central line for folding, overlapping the right air bag for folding, and dividing the air bag folded into an oblong into an upper piece and a lower piece along the longitudinal direction, wherein the longitudinal length of the upper piece is lower than that of the lower piece; winding the air bag upper piece folded in the third step for two circles to form a first air bag reel, andplacing the first air bag reel beside a gas generator in a shell; winding the air bag lower piece folded in the third step for two circles to form a second air bag reel; and placing the second air bag reel above the first air bag reel and the gas generator in the shell. A manual folding device for the air bag comprises a frame body, a guide rail, a main folding mechanism, a left folding mechanism, a right folding mechanism, a locking block, a positioning piece and a folding ruler; the main folding mechanism can move linearly front and back along the guide rail; and the left folding mechanism and the right folding mechanism can move linearly left and right along the guide rail. The move linearly has the advantages of simple structure, small floor area, light weight and convenience for operation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of automobile safety and tooling, and relates to a manual folding method and a folding device for an airbag, and is particularly suitable for folding the passenger airbag of an automobile. Background technique [0002] The existing automobile airbag assembly equipment is expensive, occupies a large area, is complicated to operate, and is difficult to maintain. [0003] The known embracing airbag folding machine, the notification number CN101654092A, discloses an airbag folding method and a folding device different from the present invention, including a frame, a workbench, a pushing assembly, a lifting mechanism and a control device. The mechanism is driven by a servo motor. The lower mold assembly is composed of a detachable lower mold set on the worktable, a lower mold base, and a detachable lower mold installed on the lower mold base. The lower mold is embedded in the workbench. Its disadvantages are com...
