PATENTED MAN 1 I971 3578.383




PILLOW UNIT FOR A SEAT This invention relates to a pillow unit for use with a seat or chairback and particularly to a pillow unit for use with a hack of a passenger seat in a vehicle.

Passengers often desire to sleep, particularly during long trips, on vehicles such as automobiles, buses, trains and airplanes. While conventional small pillows are sometimes available for passengers on public conveyances, such pillows do not provide transverse support for ones head, thereby making sleep particularly difficult and especially so if the vehicle is moving.

The present invention provides a pillow unit which is removably attached to the back of the seat of the vehicle at the level of the passenger's head and provides transverse support for the head of the passenger when he is in a relaxed sitting position and is attempting to sleep.

The custom of sleeping in a chair while watching television is becoming more and more established. The pillow unit embodying the invention also facilitates this practice and at the same time minimizes stiff necks due to improperly supported heads.

The pillow unit according to the invention includes a pillow which preferably is of truncated triangular shape in a generally vertical cross section taken generally parallel to the seat back. This provides a supporting surface for the head located at an angle to more fully contact and support the side of the head and the cheek of the passenger and also forms a lower corner which fits comfortably between the shoulder and cheek, adjacent the neck. The pillow preferably is attached to a base sheet which-provides a semirigid supporting base for the pillow when attached to the seat back. The attachment to the seat back can be by means of elastic straps or by hooked patches or strips affixed to the back of the pillow unit and mating with looped pile portions suitably stitched or otherwise affixed to the seat. Other means, such as adhesive strips, snaps, zippers or brackets can also be used to attach the pillow unit to the seat back.

In a preferred form, the pillow unit includes a cover with a removable pillow insert which can be removed when the cover and the base member or sheet, if used, are to be cleaned. The pillow unit also can employ two pillows which are spacedapart a distance sufficient to accommodate the head of the person therebetween and provide transverse support for each side of the head.

It is, therefore, a principal object of the invention to provide a pillow unit for supporting the head of a person resting in a seat.

Another object of the invention is to provide a pillow unit which can be easily attached to and removed from the back of a chair or seat of a vehicle.

A further object of the invention is to provide a vehicle pillow unit for a passenger's head which more fully transversely supports the head.

Still another object of the invention is to provide a pillow unit having a removable pillow insert facilitating cleaning of the cover of the unit.

Many other objects and advantages of the invention will be apparent from the following detailed description of preferred embodiments thereof, reference being made to the accompanying drawings, in which:

FIG. 1 is a fragmentary view in perspective of a seat to which is attached a pillow unit according to the invention;

FIG. 2 is a fragmentary front view of a pillow unit with a modified seat back and showing a person in a resting position;

FIG. 3 is a plan view with parts broken away, of the pillow unit of FIGS. 1 and 2;

FIG. 4 is a rear view in elevation of the pillow unit of FIGS. 1 and 2;

FIG. 5 is an enlarged, fragmentary view in generally horizontal cross section of a slightly modified pillow unit;

FIG. 6 is a front view in perspective of a further modified pillow unit;

FIG. 7 is a rear view in elevation of the pillow unit of FIG. 6',

FIG. 8 is a rear view in perspective ofa modified pillow unit; and i FIG. 9 is a view in vertical cross section, taken along line 9- -9, of FIG. 8.

Referring to FIG. I, a seat and specifically a chair It) has a back 12 to which a pillow unit 14 embodying the invention is removably attached. The pillow unit 14 basically includes a pillow l6 and means 18 to attach the pillow to the back 12 in a substantially fixed and rigid position so as to be effectively support the head of one sitting in a chair, when relaxed.

The pillow 16 is positioned relative to the back 12 to one side of the center thereof and generally at the level of the head of the person in the seat. Preferably, the pillow is of a generally truncated, triangular shape as viewed in cross section taken in generally vertical plane which is generally to the back of the seat. The pillow thereby forms an angular headsupporting surface 20 and a lower flat surface 22 meeting at an acute angle so that the meeting edge can fit comfortably with the neck of the person, between the shoulder and the cheek, as particularly shown in FIG. 2. The surface 20 extends outwardly generally perpendicularly to the seat back but can be at anangle of as small as 45 and still provide effective support for the head of the person. Preferably, this angle is from about 60 to The surface 20 also preferably is located at an angle to the vertical of from about 45 to about 75 to provide full and yet comfortable support for the head.

The area of the surface 20 is approximately the same as the area of the profile of an average persons head, the height of the surface 20 being from about 8 to about 12 inches, approximating the distance from the chin to the top of the head, and the width of the surface 20 being from about 4 to about 7 inches, approximating the distance from forehead to the occipital area of the head. A lesser area of the surface 20provides a too concentrated and uncomfortable support while a larger area adds nothing to the effective support of the pillow and further tends to obstruct side vision of the person as well as increase the cost of the pillow and the storage space requirement, which is particularly important on public transportation.

The size of a base 24 (FIG. 5) of the pillow 16 also is of importance to the extent that it must be sufficiently wide to provide rigid support for the pillow and the surface 20 with respect to the seat back. In this regard, the base against the seat back 12 should have an average width of at least equal to that of the surface 20, The top, front, and side of the pillow opposite the surface 20 are not of critical size or shape and can be, of any suitable configuration. The overall pillow size, however, should be such that the surface 20 will be located to one side of the center of the back 12 of the seat and not extend appreciably beyond the edge of the seat, particularly for use in public transportation.

The pillow 16 preferably includes a removable pillow insert 26, as shown in FIG. 5, located within a cover 28 and removable through a slit opening 30 which can be closed by a zipper 32, snaps, Velcro, or other suitable means. With the removable pillow insert 26, the pillow unit can be more easily cleaned as is necessary from time to time.

The pillow 16 can be rigidly yet detachably affixed to the seat back 12 in a number of ways. As shown, the attaching means 18 includes a base member or sheet 34 to which the pillow 16 and specifically the cover 28 is affixed at all edges thereof so that the base sheet 34 will firmly support the pillow 16 when the base-sheet is in turn attached to the seat back 12. The base sheet 34 preferably has a height about equal to that of the pillow 16 and is of a width sufficient to extend to or near the edges of the seat back 12,

The base sheet 34 can be attached to the seat back 12 in a a number of ways. As shown in FIGS. 3 and 4, in particular, the ends of the sheet 34 each have a pair of diagonal-webs or straps 36 and 38 which join together and are connected by an elastic web or strap 40 which stretches approximately to the position shown in dotted lines in FIG. 3 to enable the straps and base sheet to be placed over the seat back 12 and firmly held in position, yet be easily removed.

A modified form of attachment is shown in FIG. 5. Here, Velcro is used, with the hook or male portion 42 of the Velcro being attached to the back of the base member 34 and with the looped pile or female portions 44 of the Velcro suitably affixed to a surface of a seat back 46, The looped pile strips 44 can be affixed to the side edges or to the front of the seat back 46, as is shown. In an automobile, for example, the looped pile portion 44 toward the drivers seat will be on the front of the seat back when a single seat back extends across the vehicle. This will be true also with any other seat backs which extend between the backs of two or more persons. The looped pile portions 44 can be stitched to the seat back, held by adhesive, or snapped on, by way of example. Further, snaps can be directly used between the base sheet 34 and the seat back 46 or zippers can be used, with one strip of the zipper attached to the base sheet 34 and the other attached to the seat back.

The use of the straps 36-40 or the Velcro portions 42 and 44 are preferred to snaps and zippers in most instances, however, because the former two means of attachment enable the pillow unit 14 to be infinitely adjustable over a vertical portion of the seat, whereas the snaps and zippers are more limited to a particular vertical position. Consequently, no adjustment can be made for people of different heights. A plurality of snaps can be used for limited vertical adjustment, however.

Particularly when the pillow unit 14 is to be used in public transportation, removable face sheet 48 for the surface 20 can be employed which can be easily removed for cleaning. The face sheet, as shown in FIG. 3, can be attached to the top of the pillow 16 by a Velcro strip 50. Also, when the pillow is used on many airplane or train seat backs, these already have a detachable head sheet or doily 52 thereon and this doily, as shown in FIG. 2 can be raised and placed over the base sheet 34 so that all surfaces contacted by the person s head are protected by removable and washable protective covers.

It will be understood that the base member 34 can be eliminated entirely with the straps 36-40 or other attaching means being affixed directly to the base portion 24 of the pi]- low 16. This is particularly true where the head doily 52 in employed, which can be placed over the straps 3640 to substantially eliminate any discomfort such straps might otherwise impart to the person sitting in the seat.

In some instances, an example of which is when a seat and seat back are narrow, a two-pillow unit 54, as shown in FIG. 6 and 7, may be preferred to the single pillow unit 14. In the two-pillow unit 54, two individual pillows 56 and 58 are employed. These pillows have surfaces 60 and 62 which support the head either simultaneously or individually when the head is rolled slightly from side to side, depending upon the spacing of the pillows 56 and 58. The surfaces 60 and 62 can flare outwardly so that they form more acute angles with the seat back than is true of the surface 20 although the angles will preferably still be more than 45. However, whereas the surface 20 is preferably positioned close to an angle of 90 with the seat back, the maximum angle for the surfaces 60 and 62 preferably is in the order of 75. Otherwise, the pillows can be similar to the pillow 16.

A base member or sheet 64 in this instance has two back slits or openings 66 and 68 through which pillow inserts can be removed. Also, rather than continuous strips of hook portions of Velcro, several patches 70 can be used to reduce the overall material need. These in turn can be detachably connected to either patches or continuous vertical strips of the looped pile portion of the Velcro fastening material on the seat back.

Referring to FIGS. 8 and 9, a pillow unit 72 is designed particularly for use in automobiles or for other seats in which the back terminates at approximately the level of the shoulders. A base member 74 is rigid, in this instance, shown being made up of a plurality of metal straps, as shown in FIG. 8. A pillow 76 extends forwardly with an angular head-supporting surface 78 positioned similarly to the supporting surface 20 of the pillow 116. A flat, base pillow 80 is employed in this instance on the rigid base member 74 to cushion the head.

The base member 74 can be removably attached to the seat back and for this purpose has two inverted U-shaped brackets 82 and 84. In this instance, the brackets are sim ly placed over the top edge of a seat back 86 to hold the pil ow unit in place adjacent the seat back, but with a portion extending thereabove. The pillows 76 and 80 can be attached to the base member 74 by any suitable means, such as snap straps 88. Rather than employing the U-shaped brackets 82 and 84, particularly with later model automobiles having built-in headrests, the pillow unit can employ a post extending downwardly and designed to fit into the track which otherwise carries the conventional headrest.

Numerous modifications of the above-described embodiments of the invention will be apparent to those skilled in the art, and it is to be understood that such modifications can be made without departing from the scope of the invention, the embodiments shown and described being primarily for purposes of illustration and not limitation.
