Problems solved by technology

[0010] However, when the driver in the off-position posture has an unexpected accident such as a frontal collision, the deployment speed of the air cushion is too fast, and in the initial stage of deployment, the front surface of the air cushion quickly pops up to the driver's side
Therefore, the deployment pressure of the air cushion is transferred directly to the driver to deliver a severe blow to the driver's swinging torso, causing serious injury to the driver's chest

[0028] figure 1 are a front view and a rear view of an air cushion front surface and an air cushion rear surface in a driver's airbag according to a first embodiment of the present invention; figure 2 is a sectional side view of the air cushion in the driver's airbag according to the first embodiment of the present invention.

[0029] refer to figure 1 and 2 , the driver's airbag according to the first embodiment of the present invention includes an inflator 10 for generating gas when a vehicle collides;

[0030] Exhaust holes (not shown) for exhausting gas are formed on one side of the air cushion 20 . The vent hole prevents the rapid deployment of the air cushion 20 in the initial stage by discharging the high-pressure gas introduced from the inflator 10 to the air cushion 20 when the air cushion 20 starts to expand, and is introduced from the inflator 10 to the air cushion 20 by continuous discharge after the air cushion 20 is fully deployed. The gas in the air cushion...

Abstract

The present invention discloses a driver's air bag which can prevent a driver from being injured by a shock applied to the driver's chest at an initial stage of deployment because a portion corresponding to the chest of the driver is not fully deployed at an initial stage of the deployment of an air cushion by comprising: a cushion front surface to be brought into contact with a driver upon inflation of an air cushion; a cushion rear surface disposed at an opposite side of the cushion front surface, and having an inflator hole formed thereon; and first and second tethers which are disposed, spaced apart from each other, with respect to the inflator hole, and within the air cushion, with first ends thereof being fixed to the cushion front surface and second ends thereof being fixed to the cushion rear surface.

Description

technical field [0001] The invention relates to an automobile safety air bag, in particular to a driver air bag. Background technique [0002] Usually, in a car collision, due to the inertial force of the moving vehicle, the driver's body swings forward rapidly, and the upper chest hits the steering wheel, and serious injuries may occur. [0003] In order to prevent such injuries, generally, an airbag is installed at the center of the steering wheel, and the airbag is deployed in a frontal collision to ensure the safety of the driver. [0004] The airbag includes an inflator and an air cushion, the inflator contains explosives, and the air cushion is inflated and deployed by the gas generated by the explosion of the explosive in the inflator, thereby protecting the driver. [0005] The air cushion includes an air cushion front surface in contact with the driver and an air cushion rear surface disposed on the opposite side of the air cushion front surface. [0006] Also, in...
