FABRIC KNEE AIRBAC FOR HIGH INTERNAL PRESSURES

摘要

A fabric knee airbag (110) that is capable of withstanding high internal pressures is provided. The knee airbag (110) is formed from one continuous fabric sheet. The knee airbag (110) has a plurality of loops (125) formed in the walls of the airbag. Internal tethers are disposed within the airbag cushion and are attached to oppositely facing loops (125). The internal tethers (136) enable the airbag to withstand the high internal pressure by maintaining the airbag (110) at a constant volume and shape upon activation by an inflator. The knee airbag further includes an external tether (142) attached to the exterior of the airbag wall to control the direction of the deployment of the knee airbag.
