Abstract
A portable airbag system including a portable airbag mechanism which may be carried and moved by a vehicle occupant. The airbag system includes an impact sensor operated independently from or in cooperation with at least one fixed airbag mechanism mounted in a motor vehicle. The portable airbag mechanism has arranged therein an airbag which is inflated and deployed upon occurrence of a vehicle collision. A controller applies an actuating signal to the portable airbag mechanism when the vehicle collision is sensed, thereby allowing the bag arranged in the portable airbag mechanism to be inflated and deployed.

wherein actuation and an operational status of the portable air bag mechanism are adjusted depending upon at least one of a posture and a physical condition of an occupant, existence of a child seat and a hardness of a colliding object. -
8. The portable air bag system as set forth in claim 1, wherein the portable air bag mechanism comprises:
-
an air bag body;
an air bag arranged in the air bag body, for being inflated and deployed by gas flowed therein through an inflator;
a transmitter/receiver unit positioned on a side of the air bag body, for wirelessly receiving an actuation signal upon occurrence of the collision and transmitting the actuation signal to an internal communication device so that the air bag is actuated under the control of the control means; and
a wired communication cable for wiredly connecting the internal communication device and the control means with each other, upon occurrence of the collision, so that the air bag is actuated under the control of the control means.
