Passenger protection apparatus
First Claim
1. A passenger protection apparatus mounted on a vehicle, comprising:
- a detecting device for foreseeing and detecting a collision of the vehicle,a passenger protection device to be situated between a passenger and the vehicle for protecting the passenger upon the collision, said passenger protection device comprising an expandable/contractible airbag,a driving device attached to the passenger protection device for driving the passenger protection device reversibly in a direction approaching the passenger and a direction away from the passenger, anda control device for controlling the driving device according to information of the detecting device, said control device controlling the driving device to partially expand the airbag prior to the collision from a first position to a second position toward the passenger when the detecting device foresees the collision, and to contract the airbag from the second position to the first position when the collision is avoided,wherein said driving device includes a gas supply device capable of feeding gas to the airbag, a gas discharge device capable of discharging the gas in the airbag, and an urging device for urging the airbag toward the first position.

Abstract
A passenger protection apparatus is mounted on a vehicle, and includes a detecting device for foreseeing and detecting a collision of the vehicle; a passenger protection device to be situated between a passenger and the vehicle for protecting the passenger upon the collision; a driving device for driving the passenger protection device reversibly in a direction approaching the passenger and a direction away from the passenger; and a control device for controlling the driving device according to the detecting device. The control device controls the driving device to move the passenger protection device prior to the collision from a first position to a second position closer to the passenger than the first position when the detecting device foresees the collision. The control device controls the driving device to move the passenger protection device from the second position to the first position when the collision is avoided.

7. A passenger protection apparatus, comprising:
-
a passenger protecting device attached to a seat in a vehicle for protecting a passenger in the seat upon a vehicle collision, and including an expandable/contractible airbag, a driving device attached to the passenger protecting device for reversibly driving the passenger protecting device between an ordinary housed state and a collision-preparing state, said driving device including a gas supplying device for feeding gas to the airbag and a gas discharging device for discharging the gas in the airbag, and a control device connected to the driving device for controlling the driving device to partially expand the airbag from the ordinary housed state as the collision-preparing state prior to the vehicle collision when the vehicle collision is foreseen, said control device controlling the driving device to return the airbag from the collision-preparing state to the ordinary housed state when the vehicle collision is avoided. - View Dependent Claims (8, 9, 10, 11, 12)
