1. A side airbag device, comprising:
- an inflator;
an airbag including an upper cushion to be deployed by a gas pressure supplied from the inflator;
an upper guide connected at a first end thereof to the upper cushion of the airbag to lead deployment of the airbag; and
a medial unit coupled to a second end of the upper guide to provide an actuating force to the upper guide using the gas pressure from the inflator;
wherein the airbag is configured to pivotally unfold into a sectorial shape with respect to the medial unit, a first portion of the upper cushion moving relatively away from a second portion thereof around the medial unit;
wherein the upper guide radially extends from the second end thereof to the first end thereof and leads the pivotal deployment of the airbag, the first end of the upper guide rotating around the second end thereof using the actuating force provided from the medial unit; and
wherein the medial unit comprises;
a slider moving linearly using the gas pressure; and
a gear assembly coupled with the upper guide and engaged with the slider to convert a linear motion of the slider into a rotational motion of the gear assembly and transmit the rotational motion to the second end of the upper guide.
