Patent ID: 8262129

Claim:
An occupant protection device comprising: an airbag bag body for protecting the occupant, the airbag bag body having a vent hole formed in the airbag bag body; a ventilation mechanism for adjusting an internal pressure of the airbag bag body, the ventilation mechanism having a lid member and a strap, the lid member covers the vent hole; a first gas generator that generates gas for deploying the airbag bag body; a second gas generator that generates gas for actuating the ventilation mechanism, the second gas generator is connected to the lid member by the strap, the actuation of the second gas generator actuates the ventilation mechanism such that the vent hole is opened by pulling the strap connected to the lid member so as to uncover the vent hole due to the gas generated by the second gas generator; and a control portion that performs control such that the first gas generator is actuated if a condition for actuating only the airbag bag body is fulfilled, and the control portion performs control such that the second gas generator is actuated at a timing after a lapse of a predetermined time from a timing when the first gas generator is actuated such that the actuation of the second gas generator is uninfluential on deployment of the airbag bag body, and wherein the predetermined time is different from a preset timing for actuating the ventilation mechanism.
