Wearable airbag device

A wearable airbag device adapted to be worn by a wearer for protecting the hip of the wearer, the airbag device comprising an airbag that is adapted to be put on a circumference of the pelvis of the wearer and configured to be inflated with an inflation gas, the airbag including:

• an inner wall that is configured to face the wearer at airbag deployment, the inner wall having a circumferential edge;
• an outer wall that is configured to face away from the wearer at airbag deployment, the outer wall having a circumferential edge jointed with the circumferential edge of the inner wall;
• a contact portion that is disposed in a vicinity of an upper end of the airbag as deployed and configured to be deployed at least at a side of the pelvis;
• and
• at least one protecting portion that is configured to be deployed in such a manner as to extend downward from the contact portion for covering an outer side of the trochanter of femur of the wearer at airbag deployment,
• wherein the airbag has a folded form that has a reduced width in an up and down direction compared to that of the airbag in an unfolded state in which the inner wall and outer wall are laid flat one over another;
• wherein the folded form of the airbag is configured to allow the contact portion to be inflated prior to the protecting portion,
• wherein the wearable airbag device further comprises an outer cover that covers an outer circumference of the airbag, such that at an initial stage of airbag deployment,
• the outer cover pushes the contact portion, thereby causing the contact portion to deploy downward, and
• the contact portion pushes the protection portion, thereby causing the protection portion to deploy downward;
• and
• wherein at airbag deployment, an upper end side of the contact portion is covered by the outer cover entirely.
