SEE OR SEARCH THIS CLASS, SUBCLASS:
271+, for a motor vehicle which is provided with means for promoting the safety of the vehicle, or its occupant or load, or an external object. (Inasmuch as this subclass 133 was not within the scope of the classification project which established subclass 271, principally from former subclasses 82+, there is no assurance that this subclass does not presently contain art which is within the scope of subclass 271).
