Class 297
CHAIRS AND SEATS
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..
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, subclass 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, 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 subclass 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.

elsewhere, depending on the mode of use. Perfecting features
may result in classification elsewhere, as indicated by the
search notes below. The addition of a seat compels
classification in this class (297). However, see the Search

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.
