9l Claims.

The invention relates to headrests and more particularly to a type of such device adapted for attachment to existing constructions of automobile, bus, railway car and similar seating arrangements whereby to provide an effective and comfortable means for the support of the head of a seat occupant when such occupant desires to' assume a position for either relaxation or sleep.

While' primarily intended as an attachment to existing constructions, the devicev may be incorporated in new constructions as a unitary portion thereof. To this end, the invention consists in the novel arrangement of parts shown in the accompanying drawings in which:

Figure 1 is a perspective view of the device applied to a seat back and in position for support ofthe head in relaxation;

Fig. 2 is a similar view showing the device in position entirely supporting'the head in sleeping position;

Fig. 3 is an enlarged detail showing in dotted lines certain positions of the actual' adjustment;

Fig. 4 is a side elevation;

Fig. 5 shows the device attached to a seat of an automobile;

Fig. 6 is a section on line 6 5 of Figure 3;

Fig. '7 is a section on line 'I-'I of Figure 6;

Fig. 8 is an enlarged section through the support for the device;

Fig. 9 is a section on line 9-8 of Figure 8;

Fig. 10 is a vertical sectional View showing the invention in connection with a different form of seat back; and

Fig. 11 is a front elevation of a modified form of the invention.

More specifically, numeral Ill represents a horizontal track which is preferably tubular, closed at each end by caps il, and has a horizontal slot I2 formed therein, said slot I2 being provided in its lower edge with a plurality of notches I3, I3 for purposes hereinafter to be explained. Such track is fastened in any suitable manner to andacross a seat back B.

Mounted'for horizontal travel within the track I is a slide I4 carrying ball bearing devices I5, I at each end and having an extension I5 projecting therefrom, and of the same diameter in cross section as the diameter of the notches I3. Carried by the extension I6 exteriorly of track I0 is an enlarged plate I1 having a central bore I8 terminating in a cut-out portion or recess I9 in the slide I4.

In the bore I8 is journalled a rod 2l) which is an integral extension of a head 2l. Located within the recess I9 of thefslide I4 is a coiled spring 22 surrounding therod '2U-and serving by means of a cotterpin or similar device 23 and washer 24 to normally retract or force the rod 2l) and the head 2I carried thereby rearwardly into the position shown in Figure 8. A suitable cover device 25 is applied over the'recess I9'.

The outermost face ofthe plate I'I is provided with a plurality of pins or projections 26, 26 adapted to engage, at the will of the operator, withY a series'of holes 2l, 21 cut in the rearward face ofthe head 2|.. Thehead 2I is further forwardly extended to provide an eye 28.

Attached to the eyev 28 isa suitable rest or support for the head which is generally designatedA. Such'rest A may be of any preferred construction and, for instance, has a frame member 29 therein, one end of which is of socket form as at 3i!r and in which the head 2l is disposed. Such socket 30 is relatively large with respect to the head 2l, andthe latter isv pivotally'connected thereto by a pin or the like 3I.

The frame 29' isrof skeletonized` form having for instance one or`more separated arms 32. A leather, mohair', rubber; textile fabric or other flexible exterior envelope-like covering 33 encloses the frame 29 and is fastened at 34 around the socket 3i! thereof. Within the covering 33' I. use suitable cushion structure which may consist of interconnected coil springs or other cushioning devices 35 positioned by arms 32, and between the devices 35 and in contact with covering33; I use padding of brous material, feathers, down or the equivalent 35.' Said springs 35, in addition`V to their cushioning function, aid greatly in maintaining the general shape and contour of the rest A.

It is to be understood that said rest A may be rendered flexible or upholstered in any suitablemanner as that described is but one example. For instance, I may resort to a body disposed about the frame 29, without the springs, and which body may be of sponge rubber or any equivalent thereof.

Arms 32 preferably terminate a distance above the lower end of the rest A in order to provide maximum softness by flexibility at such end as is desirable if the head of the passenger engages only that high. Also the outer convex portion of the rest A should have maximum softness of flexibility to engage the head when the latter merely rests thereon and to this end the arms 32 are located approximately centrally within the rest or otherwise spaced from such convex portion'.

Figures 1V and 2 make it clear that the rest may be engaged by the head at either the right or left. The rest A may be moved as a whole axially of the track I upon lifting the rest sufliciently to disengage the extension I6 from the adjacent'notch I3 and then sliding the rest with such extension moving in slot I2 to the desired position and permitting it to drop into the adjacent notch l3. The rest may be adjusted to and secured at any desired angle by pulling the rest outwardly against the tension of the spring 22 sufficiently to disengage head 2l from the projection 26, then turning the rest about the axis of rod 2D and releasing the rest so that the A openings 21 register with and receive the adjacent registering projections 26. In this manner,

the two angular adjustments of Figures 1 and 2 may be obtained and the rest may be adjusted from the normal full line position in Figure 3` to the dotted line positions at either side thereof shown in the same figure, particularly so that the rest will be disposed at such an angle that the head may engage the upper portion thereof without contact of the shoulders or the body with the same.

It will be realized too that the headrest may turn on the axis of rod a full 360 so that the headrest may be moved entirely above the back B out of the way or to be engaged by the head of an unusually tall passenger. It is to be understood that the rail I0 may be attached adjacent the top of the back B or at any desired elevation.

In Figure 10 the invention is used in connection with a back B' which is much higher than the back B. In connection with this back B the invention is located interiorly of the back and usually in spaced relation to the top, the same reference characters being applied to my improvements as in the preceding form with the exception that the laterally sliding movement of the extension I6 is accommodated in a transverse opening or slot 31 provided in the upholstery of the said back B', as shown.

Another modification is illustrated in Figure 11 where the invention is used at both sides of a back B" of the general type shown in Figure 1U. In this form of Figure 11 the invention is used at both the right and left hand sides of the back with the rail I0 extending completely across the back interiorly thereof or with separate rails relatively short, with the extensions I6 extending through relatively short openings or slots 38 in the back B.

If desired the invention in the form of Figure 11 need not provide for sliding movement of the headrests but such headrests are mounted for the swinging movement or angular adjustment as in all of the preceding forms'.

When it is desired to rest the head against the device merely for relaxation, as best suggested in Figure 1, the side of the' head will engage the rest and at the same time the back of the head will engage the upholstery at the top of the back of the seat. For sleeping purposes, as best shown in Figure 2, the rest is adjusted to the most advantageous angle and the side of the head reposes thereon and the entire weight of the head is usually imposed on the rest.

Attention is called to the fact that themovement or play permitted by the pin 3l and head 2| within the socket 30 enables the rest to be moved slightly independently of the remainder of the structure, so that the rest will accommodate itself to uneven'backs and will enable upa headrest member, and

holstery protectors to be disposed and accommodated beneath the same.

It is obvious that when the rest A is not in use, it may be located at either end of the slot l2 and tilted to the left or right as the case may be to clear the seat back.

Minor changes may be made in the physical embodiments of the invention within the scope of the appended claims without departing from the spirit of the invention.
