Airbag support device and control method thereof

Abstract

The present disclosure relates to an airbag support device and a control method thereof. The airbag support device includes an airbag cushion embedded in a side surface of a seatback and configured to be inflated and deployed forward from the seatback; a pop-up tether having one end connected to the seatback, and configured to be deployed in a direction in which the airbag cushion is deployed and to penetrate the airbag cushion; and a pop-up tether module provided on a side surface of a seat cushion, having the other end of the pop-up tether connected to an end of a tether pole, and configured so that the pop-up tether between the seatback and the tether pole is pulled while the airbag cushion is deployed to support the airbag cushion by the pop-up tether in a portion penetrating the airbag cushion.

Description

technical field [0001] The present invention relates to an airbag support device which supports a side of the airbag while a pop-up tether is fixed to the front of the airbag to ensure a lateral support force of the airbag and a control method thereof. Background technique [0002] In the case of conventional seats, the center box can be supported by the vehicle's center console to prevent occupants from leaving the seat in the event of a side collision. [0003] However, since the self-driving vehicle employs a rotatable swivel seat and thus does not have a support such as a center console, it is difficult to support passengers. [0004] In addition, since various occupant postures may occur, it is difficult to stably support the occupant when the occupant's sitting position and posture are not in the upright sitting posture on the seat. [0005] Therefore, although an airbag system capable of restraining an occupant regardless of the collision direction has been proposed,...

Problems solved by technology

[0003] However, since the self-driving vehicle applies a swivel seat that can rotate, it does not have a support such as a center console, so it is difficult to support passengers

[0004] In addition, since various occupant postures may occur, it is difficult to stably support the occupant when the occupant's sitting position and posture are not in the upright sitting posture on the seat

[0005] Therefore, although an airbag system capable of restraining a passenger regardless of the collision direction has been proposed, there is a problem of limiting the restraining force of the passenger
