    Abstract

    The invention is directed to a keyboard where the keys are raised up from a retracted position upon the initialization of usage of the keyboard. An embedded airbag mechanism is self-inflatable to raise keys to the normal operating heights. The keys will be retracted when the airbag is deflated. The rising and retracting of the keys can also be controlled by hinge-like structure. The close and open of the cover of a laptop computer will activate the mechanism to raise and retract the keys on the keyboard.
