DEFINITION

Classification: 267/2

(under the class definition) Spring devices under the class definition which includes a spring element to cushion relative movement between parts of a vehicle and which do not involve in their application to such use any substantial modification of the vehicle structure.

(1) Note. Generally, those patents which have no disclosure for vehicular use have not been cross-referenced to this and indented subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

113, through 182, appropriate subclass for a spring device of the nonsupport type useful in vehicles, or for supporting supplementary vehicle equipment (e.g., seat, motor, transmission).

SEE OR SEARCH CLASS

180, Motor Vehicles, appropriate subclasses for motor vehicles in which there is a special relationship between a spring element and parts peculiar to motor-vehicle construction.

244, Aeronautics, 104, for spring devices disclosed and claimed in combination with parts peculiar to airplane construction.

280, Land Vehicles,

5.5+, for a general utility land vehicle including an active suspension responsive to a force encountered while the vehicle is in surface traversing motion which usually involves a spring device or element; subclasses 6.15+ for a general utility land vehicle including means, interposed between a vehicle body, chassis, or frame and running gear thereof, for altering height or levelness of the vehicle body, chassis, or frame which may or may not involve a spring device or element; subclass 79 for a general utility wheeled land vehicle provided with springs between the wheel or wheels and the load-support, noting the search notes provided therein; subclasses 124.1+ for a general utility wheeled land vehicle running gear suspension arrangement; or subclasses 275+ or 283+ for a general utility occupant propelled-type land vehicle including yielding framework or running gear which may or may not involve a spring device or element (it is noted that in accordance with the (2) Note of Class 280,

subclass 200, motorcycle frames and running gear, without features causing classification in Class 180, Motor Vehicles, are included in these subclasses). Patents classified in this class (Class 267) as originals may include vehicle parts directly related to vehicle suspension (e.g., fluid damper, upper or lower control arm) and vehicle parts which are nominally recited as either a reference or mounting structure for the spring.

297, Chairs and Seats,

195.1+, for springs used in saddle seat construction; subclasses 285+ for springs used in chairs and seats so that a back is resiliently supported; subclass 312 for springs resiliently supporting independently movable sections of a seat bottom.
