The present invention relates to a device for flipping an airbag, and more specifically, as the airbag cushion is turned over by suction of the suction blower while the air inlet of the airbag cushion is mounted on the inlet side of the outside of the housing and flows into the airbag suction space part inside the inlet. The present invention relates to an airbag flipping device in which the airbag cushion can be quickly and easily turned over.

In general, an airbag is a device that prevents an occupant from hitting an internal structure of a vehicle body such as window glass due to inertia when a vehicle crashes.

An airbag cushion is provided in the airbag, and in the event of a vehicle collision, the airbag cushion is instantaneously inflated by receiving compressed air. The inflated airbag cushion prevents the occupant from directly colliding with the vehicle body structure.

In the airbag cushion, various types of independent sewing materials are sewn and completed by a sewing machine. When the sewing is completed, the airbag cushion is turned over to complete the airbag cushion production.

At this time, in order to turn over the airbag cushion in which the sewing is completed, the operator puts his hand toward the air injecting side of the airbag cushion and pulls the inner opposite side toward the air injecting side to pull out the airbag cushion.

However, since the air injection portion of the airbag cushion is not formed with a large diameter and is not highly elastic due to the material characteristics of the airbag cushion made of a fiber material, there is a problem in that a considerable amount of work time and difficulty are caused for an operator to manually turn the airbag cushion over.

Accordingly, it is urgent to develop a device for automatically flipping the airbag cushion.

In addition, a discharge door 60 is formed to carry out the airbag cushion introduced to one side, and the discharge door 60 may be configured to be opened and closed by the air cylinder 70.

At this time, a driving button unit 71 for controlling the driving of the air cylinder 70 is formed on an external side of the housing 10 so that opening and closing is interrupted by a button operation of an operator.

Also, the airbag suction space portion 20 is preferably formed with a see-through window 21 so as to check whether the airbag cushion flows into the space in an inverted state.

After driving the suction blower 40 through the see-through window 21, the operator can check the quantity of the airbag cushion introduced and whether it is normally turned over, and then open the discharge door 60 at an appropriate time so that the airbag cushion can be taken out. do.

On the other hand, the inlet 30 is provided with a communication space so that the airbag cushion is mounted on the outside and the airbag suction space portion 20 and the housing 10 communicate with each other, so that the airbag cushion mounted from the outside of the suction blower 40 It is provided to flow inside when driving.

The inlet 30 is composed of a flat end portion 30b on which the air injection portion side of the airbag cushion is mounted, and an inclined portion 30a extending from the flat end portion 30b to guide the inflow of the airbag cushion.

The inclined portion 30a is preferably formed with an inclined surface such that the diameter gradually decreases toward the flat end portion 30b from the airbag suction space portion 20.

In addition, the suction blower 40 is formed on one side of the housing 10 and is provided to suck air in the airbag suction space portion 20, and the suction blower 40 is provided with an airbag suction space portion 20 on one side. It is connected to the connection pipe 50 to be connected to the communication and the discharge pipe 51 to discharge the air sucked outward from the housing 10 to the other side, and the housing through the discharge pipe 51 by introducing the outside air into the inlet 30 (10) Air flow is induced through a path discharged to the outside.

In order to increase the air intake amount and intensity, the drawing of the present invention shows a pair of suction blowers 40, but it can be formed in one or three or more places as necessary.

In addition, the present invention may be configured to also control the rotational direction of the suction blower 40 when controlling the driving control unit 80. When the airbag cushion is mounted, the rotational direction of the suction blower 40 is the same as the air transport path described above. It can be rotated to be conveyed in the opposite direction and can be rotated to be immediately conveyed in the forward direction when the mounting is completed.

The reason for controlling the rotational direction of the suction blower 40 in the reverse direction and the forward direction is that when the airbag cushion is mounted, only the air injection unit is mounted on the inlet 30, so the large size airbag cushion is loaded on the opposite side of the mounted air injection unit. By this, the airbag cushion is forced to be lowered and mounted.

When the suction blower 40 is driven in this state, the suction force is not properly transmitted to the entire airbag cushion and is turned over so that the airbag cushion is not sucked into the airbag suction space part 20.

Therefore, in order to release the bent state, the operator mounts the air injection unit at the inlet 30 and simultaneously expands the airbag cushion while driving the suction blower 40 while flattening and unfolding the work. Cause discomfort.

Accordingly, as described above, when mounting in the rotational direction of the suction blower 40, it rotates weakly at a constant pressure in the reverse direction, and when the mounting is completed, when it rotates through strong pressure in the forward direction, the suction force of the suction blower 40 in the state where the airbag cushion is extended As this is transmitted, the operation of opening the airbag cushion by the operator one by one may be omitted.

FIG. 5 is a view showing an inlet according to another embodiment of the present invention, and FIG. 6 is a cross-sectional view taken along line A-A 'in FIG. 5.

Referring to the drawings, the inlet 30 of the airbag flip device according to the present embodiment is configured such that the sub-inlet 31 extends to the inlet 30 as necessary.

The sub-inlet 31 is coupled to the inner edge of the flat end 30b of the inlet 30 made of the inclined portion 30a and the flat end 30b, and the sub-inlet 31 according to an embodiment of the present invention And the inlet 30 are screwed.

To this end, a thread is formed on the inner edge of the flat end 30b of the inlet 30, and a thread is formed on the outer edge of the engaging surface of the sub-inlet 31.

Such a sub-inlet 31 is a coupling portion (31a) for engaging the flat end portion 30b of the inlet (30), a sub-slope portion (31b) for reducing the inlet diameter, and the end of the sub-slope portion (31b) It consists of a sub-flat portion 31c extended to the side and the airbag cushion mounted from the outside.

The reason for adjusting the diameter of the inlet 30 through the sub-inlet 31 is that the type of airbag cushion is various and the volume in which air is injected is also varied, so in the case of a large volume airbag cushion, the diameter of the inlet 30 must be large. When the suction blower 40 is inhaled, it can be smoothly turned over to the side of the air bag suction space 20 and introduced.

In addition, in the case of a small-volume airbag cushion, the air injection portion is formed in a small size, so it is difficult to be smoothly mounted on the flat end portion 30b of the inlet 30 having a large diameter, and if the worker does not properly mount it, the airbag suction space portion is flipped over. A defect that does not flow into the (20) side may occur.

Therefore, it is preferable to be configured to enable the use of airbag cushions of various sizes through at least one sub-inlet 31 according to the present invention.
