CARv SEAT,-

Appncanon inea March# 1o, 1922;- serial` No. 542,555.

To all whom t may concern Y Be it known thatl, CONRADAT. HAN EN, a',

citizen of the United States, residing` at Germantown, in the' city of Philadelphia,

county of Philadelphia, and- Sftate ofi Pennf sylvaniav, have inventedY certain newfy and useful Improvements inCar Seats, of y which the.` following is a` sp'eciication,

My invention Lrel ates to car se-ats -andgrnore f particularly toa carseatdesign`ed l sol as :to y be niade almost g entirely `of finetalj and-ofi the type :commonly referred: to as rever-sible!7 whereby accommodation f oi?- different, types oif cushions may be readily ands'easily secured .by 'changinthe vheight of the rochersupportingfinembers ratherthan by increasing the size ofl the :noclreror by loweringethe. rockerl to a. p oint where it extends be-lowvthe bottonrot` the endJplat-es and-i rails, as has usually been*thecasekheretorore- A'further obj ect` of niy invention is 'to so` construct.v the i seat that no partothelmechanism extends `belowfthe rails orr endI platesv and aclear Space isprovided under. the seat for electricy heating-devices or for... luggage, etc. AaiotherY oibj ect of`v my:` invention is to providey a seatwherein the throw-lever` is adapted togive a largeaniount oi'throw tothecu'shion` and thereby tol overcomev the ob]ectionablev feature off having the cushion proj ect! inthe' rear beyond the back, and also having-the advantage of' givinga widen seating spacey onthecushion. A furtherobject'offmy in'-l ifention-.isto provide aseat-'throwing` mechanism wherein the` throw-lever, \vlie1i-i1i linal position, liesat alv sharp angle to-y the standard, thus` giving a 'betterl bearing against the standard and holdinggthe back more firmly-in place, and; givingl the bac-lr` greater stability than lhas-- beenobtainedy byI constructions heretofore known.V A further object-lofli--iny invention is toY provideya seat lia-ving an easy, operable automatic foot rest, theconstructionbeing such that there is a minimum otflost;1notion in the operatingpartsl-of'ft-he; foot-rest andY a very firm and rigid! footrail is provided. l

.Similar reference `characters* designate` similan partsthroughout the several views ofi' the' drawings. Referring tothe rdrawings, the seat back l' islsupportedi upon a pain of: oppositely disposed` standards'Q, each' having'. a pair' of.I Insteat i ot forming a.grooved: orA channeled track` roller-si?)` at' their-lower ends.

or therollersin lai inemben separate from the endiplatefand riveting-or weldimrv4 the traclcl totheend plate, Iftorm a trackl in' the-end plate 5 by cut-tingen openingcthere# inand piressingfthe edges inwardlyV tov forni' the iang'esof the traclasat, il. This leaves anfiop'ening throughthe end plate at-` the wall endl ofA the sea-t,VV but as the plate' is secureditoitheside ofthe car, this is not obj ectionable: Attheaisle end the usual thin steel' coverrplate @may beused on the outside .of the main steel plate 5 ,to cover the opening. It desired, thel {ian-ges 4 whichV form the` track maybev reinforced by pieces of=angle-y is a 'vertical'A shaped steel 7 secured by suitable means, as by welding, over the upper flange 4 just over the place where the outer roller in the standard rests when the seat back is in position for use. A reinforcement 8 may also be welded or otherwise secured at the end of the flanges 4 to take the strain of the downward pressure of the outside roller when the back is in position for use. This construction of track saves several pounds in weight and is cheaper than the separate track construction ordinarily used heretofore.

Heretofore the seat rails were attached to the wall plates by attaching steel angle plates to the ends of the seat rails and bolting the angle plates through the end plates of the seat. In accordance with my invention an angle plate 9 is permanently riveted, as at 10, to the end plate itself and the rail 11 is bolted, as at 12, to the angle plate. The advantages of this method over the other are that the steel angle plate is formed with a flange 13 which fits over the rail 1l, giving a firm bearing, and further, it permits of shipping the wall plates, as 5, in advance, where so desired by the car builder, in order that they may be attached to the steel or wood side of the car during the construction of the same. Usually, the seat must be put together, including the bolting on of the wall plate, and then the entire seat secured to the side of the car. By means of my invention, the wall plate may be attached to the wall before theconnecting rails are attached and the rails need only be bolted to the angle plates carried on the wall'plates. Ordinarily the rocker is supplied with a flange at the bottom mounted to slide back and forth in a slot cut into the angle plate or the rail. According to my invention the angle plate 9 is'made with a projection 14 extending upwardly to any required height, and with a pin 15 projecting from the top of the same. The pin is adapted to extend through a slot or groove 16 formed in the lower part of the rocker 17 and has an enlarged head 42 adapted to abut against the rocker on the opposite side. The advantage of my improved construction is that it makes possible the use of thinner, narrower and lighter rockers, and the variation in the thickness of the cushion, as required by different types of seats, may be regulated, for the most part, by the height of the projecting part 14Vof the angleplate 9 rather than by increasing the size of the rocker or by lowering the rocker to a point where it'extends below the bottom of the end plates and rails, as is the case in the usual construction of seats of similar character. It is to beobserved that by means of my invention there is no part of the mechanism which extends below the rails or end plates even when the back is in the centre and the rocker in its lowest position, and thereby an abundance of clear space is provided under the seat for the installation of electric heating devices or for the storage of luggage or other articles.

The rocker 17 is preferably of pressed steel and is adapted to support seat cushion 18 upon a horizontally extending flange 19, the cushion being held in place by the usual dowel pins 20. The rocker 17 is adapted to be operated by movement back and forth over the pin 15 projecting through the slot 16. The slot is preferably flanged as at 21, and is so shaped as to lower the rocker as it passes under the back when the latter is in a central position (see Fig. 2) and gives an end bearing on both sides when the rocker is in its final position and the seat ready for occupancy. If desired, the .end of the slot 16 may be provided with a slight depression, as at 22 (Fig. 7) in the upper part thereof thus locking the seat to a slight extent when in position for use. The central portion of the rocker slot 16 may be provided with a larger opening, as at 23, which permits the head 42 of the pin 15 to pass therethrough. Thus, the rockermay be removed by moving the back into central position which brings the enlarged portion 23 of the rocker slot 16 opposite the pin 15 and permits the head 42 to pass through the slot in the rocker.

The numeral 24 designates a double throwlever, which is pivotcd as at 25 intermediate its ends to the end plate 5, instead of having its pivotal point on the cross-rod as is usually the case. The upper end of the throw-lever 24 has a pin 27 slidably mounted in the vertical slot 26 in thc supporting standard 2, and the opposite end of the lever 24 is widened out as at 28 and carries two pins 29 and 30, respectively, in separated relation. Two flanged slots are provided on the rocker 17 adapted to cooperate with the pins 29 and 30 to effect the movement of the cushion when the seat back is moved. As shown, the flanged members may comprise channel pieces secured to the rocker, one of said ,pieces 31 being provided for the pin 29 and the other 32 being provided for the pin 30. Pins 29 and 3() and the slots 31 and 32 are So arranged that when the seat back is in position for use (see Fig. 1) one of the pins, such as 30, will be in the slot of the member 32 provided therefor, the pin 29 being separated from its cooperating slot member 31. When the seat back is moved toward the central position, pins 29 and 30 rotate about 'the pivot point 25 of the lever and the pin 30 will cooperate with the flanged slot member 32 to push the rocker 17 and the seat cushion 18 in the reverse direction, pin '29 meanwhile approaching its slotted member` 31. VVh-en the seat back is in central position (see Fig. 2) the construction is so designed that both the pins 29 and 30 will be seated in their respective flanged slot members 31 and 32. Then when the seat back is to leave its slotted flange member 32 but causes the cooperation between the pin 29 and 1ts slotted fiange member 3l to continue the movement of the rocker 17 and the seatcushion 18 in the reverse direction to the n'iovement of the seat back 1.

It is to be noticed that one of the. pins, 29 or 30, Ais at all times in one of the flanged slot members 3l or 32 of the rocker 17 and a continual positive and firm connection is n'iaintained between the throw-lever 2li, the seat standard 2 and the rocker 17. The cushion 13 is moved a considerable distance and a sufficient distance to overcome the objectionable feature of having the cushion project in the rear beyond the seat back, and moreover has the advantage of giving wider seating space on the cushion. lt is also to be noticed that by means of my construction the throw-lever 2li, when in final position, lies at an angle which is less obtuse than -is usual in s of this character. Thus, my in\f*ention secures a better bearing at the upper portion of the lever 241 against the standard 2, the result being, that while the back 1 may be moved with sufficient case, it 'is held' firmly in place when in position for use and greater stability is given to the back. The flat position of throw-lever 2a also increases the throw of the cushion.

iis a modification of my invention, instead of providing two pins, such as 29 and 3l), on the throw-lever 24 and two cooperating flanged slots, as provided by members 31 and 32 on the rocker 17 to cooperate, with theseA pins, l may provide a single pin or other element 33 which .is adapted to cooperate with a single 'flanged slot 34 in the rocker 17 to effect the reverse movement of the seat-cushion whenever the seat back is nioved. This modification is illustrated in Fig. (i wherein the throw-lever 24 is not widened at its lower end but carries an oscillating rod 33 which is continually seated in a vertical slot 3a formed in the rocker 17 and cooperates therewith to effect the desire-:l throw of the cushion. Although this single pin connection does not give quite as much throw to the cushion as the double pin arrangement above described, however, on account of the 'flat position of the throwlever 2e', a considerable amount of throw is obtained.

between the two ends of the seat, I provide an oscillating rod 33 extending from end to end of the seat, each end being mounted as at 35 to the lower end of the throw-lever 24. Formerly, this rod 33 was projected into an opening in the end plates of the seat and was attached thereto. By my construction it is easy to adapt an automatic foot rest for operation by the oscillating rod 33.- The foot rest comprises a foot rail 36, extending frc-m side to side under the seat. Each end of the rod 36 is supported by a metal lever arm or hanger 37 which is pivoted as at 33 to a light steel bridge 39 attached at each end and supported by connecting rails 11. The lever 37 has a portion 40 beyond its pivot point 33, which portion is provided with a flanged slot al in which the oscillating rod 33 is adapted to move and with which the oscillating` rod 33 cooperates to effect they desired movement of the lever 37 and the foot rail 36. This method does away with the usual cog and pinion members required to reverse the motion of the foot-rest and ordinarily found in seats of this character. lt is also to be noticed that the operating parts of the foot rest and the foot rail itself is very firm and rigid since the foot-rest hanger or lever 37 has its bearing at the tcp against the oscillating rod 33 which is attached to the ends of the throw-le\f'ers 2li, these levers 24 being pivoted as at 25 into the end plates 5 of the Seat.

This seat may be mounted .in a car in any one of a number of well known fashions. -For instance, a pedestal may be supplied and may be attached to the rails'll in the usual manner. Obviously, an arm rest may be attached to the aisle plate by bolts or other well known means, if desired.

As many changes could be made in the above construction and as many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all mattercontained in the above description, or .shown in the accompanying drawings shall be interpreted as illustrative and not in a lii'niting sense.
