Pedestrian protection airbag system
First Claim
1. A pedestrian protection airbag system mounted on a vehicle comprising:
- a control unit which receives signals from a sensor capable of detecting a pedestrian;
an airbag for thrusting out from an airbag storage portion by inflation so as to deploy between said pedestrian and said vehicle;
an inflator for supplying inflation gas to said airbag; and
a thrust assist for facilitating said airbag to thrust out from said airbag storage portion;
wherein said control unit receives the signal from said sensor to perform a touch detection in which said control unit anticipates that said vehicle will touch said pedestrian, and an approach detection in which said control unit detects said pedestrian approaching said vehicle;
wherein said control unit actuates said thrust assist when the approach detection is performed; and
said control unit actuates said inflator when the touch detection is performed.

Abstract
A pedestrian protection airbag system includes a control unit, an airbag, an inflator, a movement unit for moving a cover member to thereby allow the airbag to thrust out from an airbag storage portion smoothly, and a drawing unit for drawing out the airbag. The control unit receives signals from sensors, and can perform detection in two stages. In one of the stages the control unit performs touch detection such that the control unit can anticipate that a vehicle will touch a pedestrian, while in the other stage the control unit performs approach detection before the touch detection such that the control unit detects the pedestrian approaching the vehicle. The movement unit and the drawing unit are actuated by the control unit detecting a pedestrian approaching the vehicle. The inflator is actuated by the control unit detecting calculated touch to the pedestrian.
