Abstract: An air conditioner for a vehicle with an improved structure so that hot air is not directly discharged to a defrost vent in a floor mode or a mix mode, includes an air conditioning case in which an air flow path is formed, and a cooling heat exchanger and a heating heat exchanger provided sequentially on the air flow path of the air conditioning case in an airflow direction, wherein a defrost vent, a face vent, and a floor vent are formed on the air conditioning case, wherein the defrost vent includes a first defogging flow path allowing air passing through the heating heat exchanger to be discharged directly, and a second defogging flow path allowing air passing through the cooling heat exchanger or the heating heat exchanger to be mixed and discharged therethrough.

Abstract: A memory device for seat belt length in automobiles is fabricated in such a manner that bar codes having some location information are attached to the seat belt so that a bar code reader can detect said information and remember the preferred length of the seat belt for a particular user. Thus, when the user fastens the seat belt, the device automatically adjusts the seat belt length onto him with a comfortable length. By remembering the preferred length of a particular user, such remembered length allows him to quickly and easily fasten his seat belt at a more convenient length.
