VEHICULAR PEDESTRIAN PROTECTING AIRBAG DEVICE

摘要

A vehicular pedestrian protecting airbag device that is capable of suppressing increases in weight and cost accompanying reinforcement measures, and capable of maintaining good pedestrian protection performance of an upper face of a hood. An automobile pedestrian protecting airbag device is installed at a vehicle lower side of a rear end section of a hood at a vehicle rear side of a protruded portion. A pedestrian protecting airbag and an inflator are installed inside a module case. The inflator is attached to a bottom wall of the protruded portion by inflator attachment brackets each formed with an excess length portion at an intermediate portion. Accordingly, when the inflators attempt to move toward the vehicle front side due to deployment reaction force of the pedestrian protecting airbag, the excess length portions are compressed and deform to enable the deployment reaction force to escape.

主权项

1. A vehicular pedestrian protection airbag device comprising:
an inflator that is installed at a lower side of a rear end section of a hood capable of being raised toward a vehicle upper side at the rear end section, and that ejects gas on actuation; a pedestrian protection airbag that is stowed in a folded state at the lower side of the rear end section of the hood, and that inflates and deploys from between the rear end section of the hood and a windshield glass toward a vehicle upper face side and a vehicle rear side by being supplied with gas from the inflator; and an inflator attachment bracket configured including a first fixing portion fixed to a lower face side of the rear end section of the hood, a second fixing portion to which the inflator is fixed, and a deformation portion that is provided between the first fixing portion and the second fixing portion and that plastically deforms by stretching or compressing so as to permit movement of the inflator toward an opposite direction from an inflation and deployment direction of the pedestrian protection airbag.
