IPC: B60R21/232
Filed: 2018-10-03
Abstract: To provide a vehicular curtain airbag device capable of obtaining occupant restraint performance both in a state where a center pillar garnish and a seat back overlap each other in the vehicle side view and other states.SOLUTION: When a curtain airbag 16 is inflated and deployed, an independent part 54 is inflated and deployed to a vehicle lower side toward a space between a seat back 58A and a center pillar garnish 50, and the independent part 54 interferes with the seat back 58A and thus is lifted so as to become a state of bending in a vehicle width direction. In contrast, portions other than the independent part 54 of the curtain airbag 16 can be relatively displaced to the independent part 54 due to a slit part 52 and thus can be inflated and deployed to the vehicle lower side without being affected by the position of the independent part 54. Therefore, the positional change of the curtain airbag 16 between a comfort state and other states can be suppressed. As a result, occupant restraint performance can be obtained both in the comfort state and other states.SELECTED DRAWING: Figure 5
