ABSTRACT:
The airbag of the vehicle according to the present invention can suppress initial deployment of a cushion and minimize injury of an occupant caused by a pressure upon deployment of the cushion since outer tethers covering the outer side of the cushion are sewn and coupled to the cushion at a plurality of positions and a plurality of sewing portions are adapted to be sequentially broken according a deployment pressure of the cushion. Therefore, injury of an occupant in an OOP (Out-of-Position) condition can be prevented. Furthermore, the airbag can optimally cope with various collision modes because the outer tethers are formed in plural number and the sewing strength of the plurality of outer tethers can be adjusted. Furthermore, deviation in the performance of the outer tethers can be decreased compared to a tear line because the outer tethers are sewn to the cushion and the sewing portions are broken by a deployment pressure of the cushion. Furthermore, deviation in the performance of the outer tethers can be decreased since the outer tethers are sewn and fixed to the cushion.
