Description

Seat side air bag fastening structure {Structure for Side Air-Bag of Seat for Vehicle}

The present invention relates to a seat side airbag fastening structure, and provides a technology for a side airbag fastening structure capable of integrally supporting a frame, a covering part and an airbag module through one anchor unit.

In general, an airbag is a typical occupant protection device together with a seat belt. The airbag system consists of a detection system and an airbag module. The detection system is composed of a sensor, battery, and diagnostic device, and the airbag module is composed of an airbag and an operating gas expansion device. That is, when a collision is detected by the sensor, the operating gas device is exploded, and the airbag is inflated instantaneously due to the explosion gas.

As such, the time for the airbag to be fully activated from a collision usually has a short time of about 50/1,000 seconds. The gas used in the airbag is a high-pressure gas generated by rapid combustion of a solid or a gas stored in a high-pressure gas container.

Side airbags, which are generally installed in vehicles, operate on the same principle as the driver's side airbag, and sensors that detect side impact are built into the left and right airbags of the vehicle.

These side airbags are installed in the driver's seat and passenger's seat, and when a collision with the vehicle is detected, they may deploy simultaneously with the driver's seat airbag or only the side airbags.

That is, the side airbag installed inside the side of the seatback of the vehicle is deployed when a sensor detects an impact due to a vehicle accident, and is configured to protect the occupant from the impact generated from the side of the vehicle.

At this time, the side airbag installed on one side of the seatback pad inside the seatback is deployed to the side of the seatback through the sewing part of the seatback covering part while the airbag is deployed by a sensor.

However, in the case of the prior art, one end of the covering part and one end of the airbag module could not withstand the pressure when the airbag was deployed, resulting in damage to the covering part and the airbag module when the airbag was deployed. In addition, the airbag module was not supported by the frame, causing the airbag to collapse. There was a problem that could not be developed in the direction in which it should be developed.

In addition, there was a problem that the hook fastened to the frame was damaged and scattered when the airbag was deployed.
