Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a side air bag cover and a side air bag cover using the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing method and a manufacturing apparatus for a side airbag cover and a side airbag cover using the same and, more preferably, to a side airbag cover which improves the deployment performance of a side airbag and a side curtain airbag, The present invention is to provide a side airbag cover for promoting the productivity of the airbag cover as well as promoting the recycling of the broken airbag cover by using a sewing method which is an ultrasonic welding process.

Generally, a side airbag is deployed to protect an occupant when a side collision occurs on the side of the vehicle while the vehicle is running or stopping.

The deployment principle of the airbag deploys the airbag when it recognizes a certain acceleration value in the airbag control unit to control the airbag system while controlling the side collision detection sensor and the airbag system which senses the side impact acceleration to the side body of the vehicle.

At this time, the airbag deployment time depends on the characteristics of the vehicle. The actual collision speed and the mode of collision are experimentally determined by the actual vehicle, and the collision data is used for each collision test to determine the airbag deployment condition of the vehicle through the CALIBRATION (airbag deployment threshold and deployment time decision).

In a vehicle equipped with a side airbag, a lateral collision detection sensor for detecting a side collision acceleration is disposed on the left and right sides of the vehicle, respectively.

In other words, it is mounted on the INNER PANEL or SIDE SILL of B-PILLAR. Such a conventional airbag system is configured as shown in Fig. 1 described in the prior art of Patent No. 10-0552196.

As shown in FIG. 1, the ACU (AIR BAG CONTROL UNIT 1) is a unit having a SAFING SENSOR incorporated therein for controlling an air bag system and preventing morning opening. The DAB (Driver Airbag) 2 is a driver's seat airbag (airbag mounted on the driver's seat handle), the PAB (PASSENGER AIRBAG) 3 is a front passenger's seat airbag To the driver's seat and the passenger's seat to protect the passenger's side of the passenger seat (passengers only protect passengers).

The CAB (SIDE AIRBAG; 5) is equipped with a curtain airbag from the A-PILLAR to the C-PILLAR in the driver's seat and the passenger's seat to protect all passengers in the rear seats, while the SIS (Side IMPACT SENSOR) It measures the acceleration and sends it to the ACU.

The conventional airbag system as described above is configured to detect the acceleration value of the airbag control unit (ACU) 1 sensed by the side impact sensor (SIS) 6 and the acceleration value of the direction sensed by the SAFING sensor The deployment of the airbag is determined.

The airbag is deployed only when the acceleration value of the SIS 6 mounted on the B-PILLAR portion of the vehicle exceeds a certain threshold THRESHOLD and exceeds the SAFING THRESHOLD in the SAFING SENSOR of the ACU 1 in the event of a vehicle collision.

Conventionally, the SIS 6 may be mounted only on the B-PILLAR portion to protect the passengers of all seats in a side collision of the entire seat portion of the vehicle.

However, in a vehicle equipped with a side curtain airbag, only one of the SIS (6) is attached to the B-PILLAR portion at LH / RH to deploy the side airbag and the side curtain airbag at the side collision, The seal line of the cover is broken and the occupant is protected.

The configuration disclosed in "Airbag cushion fixing nonwoven cover and an airbag system including the same " in relation to the airbag cover is made of a polypropylene (PP) nonwoven fabric of 60 gsm type, (Stiffness) of 0.5 to 1.0 Kgf as measured by the method of ASTM D 4032, a tear strength of 1 to 10 Kgf as measured by the method of American Society for Testing and Materials (ASTM) D 2261, A nonwoven cover for fixing an airbag cushion having a sealing strength of 1 to 6 kgf / inch measured by the method of Test Association Standard (ASTM) D 5034. ", the material of the airbag side cover and the configuration of the slit of the sealing line , And a configuration disclosed as "a nonwoven cover for fixing an airbag" of Patent Registration No. 10-0904849 is a printing method for the type and model of the airbag on the surface of the airbag cover, A sewing thread (sewing thread) sewn on one side of the bur is not separated or the configuration for the sewing technique is not disclosed at all.

That is, in the conventional sewing technique of sewing the seal portion of the airbag cover, when sewing the seal portion of the airbag cover for covering the airbag as shown in Figs. 2 (a) and 2 (b) (Such as cotton yarn), it is very inconvenient to separate and remove the sewn thread from the airbag cover in order to recycle the airbag cover that has been broken after the airbag deployment.

The technique for separating and reusing the broken airbag cover after the deployment of the airbag from the sewn sewing material made of different materials is still lacking in research.
