SECTION I - CLASS DEFINITION

Devices for supporting the weight of a person in a seated position including chairs, seats, and ancillary devices not elsewhere classifiable.

(1) Note. A seat is a support for bearing the weight of a person in a sitting position. It comprises (1) a bottom contoured to conform to the shape of the buttocks of the occupant or (2) supports for two or more different areas of the occupant"s body or (3) any support surface disclosed as a buttocks support in combination with a means, such as a table, desk or an additional buttocks support, which limits the use of such surface to the disclosed use. As used in this class, the term "seat" is distinguished from the term "bottom" in that the bottom is the buttock supporting portion of a seat. For the location of the definitions of a chair, a bottom, and a back, see Subclass References To The Current Class below.

411.1,for a support engaging the armpit of a seated person.
445.1,for the definition of a chair.
452.1,for the definition of a chair back and bottom..

SECTION III - REFERENCES TO OTHER CLASSES

SEE OR SEARCH CLASS:

4, Baths, Closets, Sinks, and Spittoons,   subclasses 234+ for a closet seat with a cover or lid and subclasses 237+ for a closet seat, per se, especially subclass 239 for a detachable child"s seat. A bottom having an opening is retained in this class (297). To be classified in Class 4, additional commode structure must be present, such as a receiver, a plug for the opening, a deflector shield, means for attaching the seat to the opening, etc.
5, Beds,   subclasses 12.1+ for sofas convertible to beds, subclasses 600+ for beds having movable sections adjustable relative to each other to support an occupant in a reclining or sitting position, subclasses 131+ for cushioned supporting surfaces spaced from the floor and capable of supporting an occupant in either a recumbent or sitting position, and subclasses 652+ for cushions, per se, of general utility. The art in Class 5, especially in subclasses 12.1+ and 600+, is often structurally and functionally indistinguishable from that in this class (297).
52, Static Structures (e.g., Buildings),   appropriate subclasses for a panel of general utility even though disclosed or defined as being a component of a chair or seat.
56, Harvesters,   subclass 323 for a seat combined with a machine of that class.
70, Locks,   subclass 261 for locks for seats to prevent unauthorized use thereof.
104, Railways,   subclass 115 for a chair or seat mounted on a cable railway, e.g., a ski lift.
105, Railway Rolling Stock,   subclass 322 for railway cars having sleeping berth, wherein a seat back forms the upper berths, and subclasses 345+ for seats built in the forming parts of a car structure.
114, Ships,   subclass 194 for self-leveling chairs attached to a ship, and subclass 363 for a seat combined with a boat.
128, Surgery,   appropriate subclasses for a seat combined with a means to treat the body, particularly subclass 33 for a seat combined with a vibrating massager.
144, Woodworking,   subclasses 329+ for a process of making a chair or seat of wood.
160, Flexible or Portable Closure, Partition, or Panel,   appropriate subclasses, for a flexible or portable panel usable as a seat back or bottom, especially subclasses 87+ for plural panels; subclasses 327+ for a panel supported at opposite edges by elongated elements; subclasses 371+ for a panel mounted in a frame, and subclasses 383+ for means to fasten one edge of a fabric panel to an elongated supporting element.
172, Earth Working,   subclass 431 for a seat combined with a machine of that class.
244, Aeronautics and Astronautics,   subclass 122 for an aircraft fuselage having a seat.
248, Supports,   subclass 118 for a headrest or armrest not disclosed as used in conjunction with a device of this class (297) and subclasses 127+ for a stand comprising a generally horizontal article supporting surface combined with depending substructure to space the surface from the floor or ground.
267, Spring Devices,   subclasses 80+ for springs and their framework for bottom and back cushions. They may include diverse types of spring material such as rubber and metal, and spring structures having different coefficients of resiliency for different areas of the cushion. See, also, subclass 117 for the structure of a fluid spring for the same use; and subclasses 142+ for other types of spring elements in a spring device for such use.
280, Land Vehicles,   appropriate subclasses, for the combination of a vehicle of the type there classified and a chair or seat. The mere recitation of wheels or running gear on a chair or seat is insufficient to characterize that device as a Class 280 Vehicle; consequently patents having such structure have been classified in this class (297) on other features. However, additional vehicle features such as removable or retractable running gear, a push handle, means to propel the vehicle, a steering wheel or tiller, are examples of vehicle structure details which characterize the device as a vehicle for Class 280. Moreover, in the "baby walker" type of seat, a wheel-mounted bottom modified to enable the occupant to engage the floor or ground with his feet to move the vehicle (as by providing leg cut-outs, or by mounting the seat between the wheels) is a vehicle for Class 280. See especially subclasses 5.2+ for an invalid wheel chair having means for ascending and descending steps or similar obstructions; subclasses 7.1+ for a device convertible from a vehicle to a nonvehicle; subclasses 638+ for a seat having a running gear extensible relative to the seat to raise or lower the seat or to extend the wheels from an inoperative to an operative position; subclasses 200+ for a vehicle having occupant propelling means; subclasses 87.051+ for a vehicle propelled by the foot contact of an occupant with the floor (baby walker); and subclasses 47.38+ for a vehicle such as a baby carriage propelled by a handle.
296, Land Vehicles: Bodies and Tops,   subclasses 63+ for a seat combined with a land vehicle body, particularly subclass 64 for the arrangement of a plurality of seats within a vehicle.
446, Amusement Devices: Toys,   subclass 482 for toy chairs or seats.
606, Surgery,   subclass 242 for a seat having an orthopedic device designed to adjust unfractured bones into their normal position.

 This subclass is indented under subclass 116.  Device wherein the armrest is held in a vertical position of use by a disengageable means mounted on or connected to the back.
  
[List of Patents for class 297 subclass 118]    118CONVERTIBLE:
 This subclass is indented under the class definition.  Device wherein by removal, reorientation, or addition of one or more components, there is formed another and different structure, (1) which if claimed alone would be classifiable in another class, or (2) which if claimed separately would be classified in different subclasses in this class (297).
(1) Note. The mere adjustment of one or more body supporting parts of a seat relative to another either in body supporting range or to and from a storage position, has not been considered convertible for this and the indented subclasses unless such adjustment destroys the utility of such part as a body support. Such patents have been classified above or below with the particular adjustment claimed. See the search notes to this subclass for the loci of such art. However, if the relative adjustment destroys the utility of the device for supporting an occupant, the device is convertible and classified here. For example, if a back is moved to be coplanar with a bottom, such movement is considered mere adjustment; however, if both parts are then elevated to become a table, the elevation may be considered to destroy the utility of the device as a body support, and such art has been classified below.
(2) Note. In general, the addition or reorientation requirement of the definition of this subclass entails the employment of a member which has utility in one type of device but no utility in the other type of device to which it is converted. For example, as pointed out in (1) Note above, a back which is pivoted to move with respect to the bottom has been classified elsewhere. However, if the back pivots and moves forwardly of the bottom so that the previously unused rear surface of the back becomes a support surface such as a table, the device is considered convertible and is classified here.
(3) Note. A removably mounted body rest, although "converting", for example, an armchair to an armless chair has not been considered to render the device convertible within the scope of this and the indented subclasses. Such removable body rests have been classified with the particular rest. See the search notes below.
