Abstract
A head protection device includes an air bag and a guiding bracket, and the guiding bracket includes an attachment surface that has an attachment portion attached to a body panel, a guiding wall that has a support portion for supporting the air bag, and a contact portion that is coupled to an end of the guiding wall in the vehicle cabin side and contacts a ceiling material. A weak portion deformed toward the vehicle cabin outer side by a load of a passenger's head at a collision causing no activation of an inflator is formed between the support portion of the guiding wall and the contact portion.
Claims5
A head protection device comprising:
- an air bag covered with a ceiling material arranged above a pillar of a vehicle, the air bag pressing the ceiling material from between the pillar and the ceiling material to open the ceiling material and expanding and inflating downward when an inflator is activated to flow a gas into the air bag;
- and
- a guiding bracket covered with the ceiling material above the pillar, the guiding bracket guiding the air bag expanded and inflated by the inflator to a vehicle cabin side, wherein the guiding bracket includes:
- an attachment surface extending along a body panel in a vehicle vertical direction, and the attachment surface having an attachment portion attached to the body panel;
- a guiding wall extending from a lower end of the attachment surface toward the vehicle cabin side, the guiding wall having a support portion for supporting the air bag;
- and
- a contact portion coupled to an end of the guiding wall in the vehicle cabin side, the contact portion contacting the ceiling material, and
- a weak portion deformed toward a vehicle cabin outer side by a load of a passenger's head at a collision causing no activation of the inflator is formed between the support portion of the guiding wall and the contact portion.
A guiding bracket that is covered with a ceiling material above a pillar of a vehicle, and guides an air bag expanded and inflated by an inflator to a vehicle cabin side, the guiding bracket comprising:
- an attachment surface having an attachment portion attached to a body panel;
- a guiding wall extending from an lower end of the attachment surface in a predetermined direction, the guiding wall having a support portion for supporting the air bag;
- and
- a contact portion coupled to a front end of the guiding wall, the contact portion contacting the ceiling material, wherein a weak portion deformed toward a vehicle cabin outer side by a load of a passenger's head at a collision causing no activation of the inflator is formed between the support portion of the guiding wall and the contact portion.
