Selectively deployable airbag apparatus for vehicle and control method thereof

Abstract

A selectively deployable airbag apparatus for vehicles includes: an impact detection sensor; a seat belt sensor; a first inflator and a second inflator; an airbag supplied with gas emitted from the first inflator and the second inflator and having a base chamber and a chest chamber separated from each other by a partition with at least one inner vent hole such that the base chamber and the chest chamber fluidly communicate with each other; and a controller receiving signals from the impact detection sensor and the seat belt sensor and operating the airbag to deploy, and determining whether to deploy the chest chamber or not based on whether the passenger has fastened the seat belt or not and an impact force.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Applications 10-2006-0041221 and 10-2006-0066928 filed at the Korean Intellectual Property Office on May 8, 2006 and July 18, 2006, the entire contents of which are hereby incorporated by reference as refer to. technical field [0003] The invention relates to a selectively deployable vehicle airbag device and a control method thereof. Background technique [0004] Generally, an airbag module is installed in a steering wheel or a bumper to protect a driver or a passenger in a vehicle collision. [0005] The airbag module deploys the airbag at the time of a vehicle collision, thereby preventing a driver or passenger from colliding with a bumper or a windshield, thereby reducing injuries caused by the vehicle collision. [0006] FIG. 1 is a view showing a conventional airbag system, showing collisions related to occupant body regions (head, chest, lower bo...

AI Technical Summary

Problems solved by technology

However, in this case, the head of the passenger cannot be protected

[0009] In addition, in a situation where the movement of the chest is restricted by the seat belt, the deployed airbag hits the chest again, which may cause serious chest injury to the occupant

[0010] If the airbag is deployed with an infant or child seated in the passenger seat, the airbag is deployed in the same manner as it is for an adult, and the infant or child directly collides with the airbag 1, so that the collision energy due to the vehicle collision cannot be softly absorbed absorbed, and passed directly to passengers, which could cause serious injury
