Preferred embodiments of the invention will now be described in conjunction with the accompanying drawings in which:
As a result of the resiliency of the rubber bushing 30 and the empty lower portion of the mounting bracket bore that is left unoccupied by the bushing 30 to provide clearance between the upper shaft section 12a and the inner wall of the mounting bracket, the pole 12 is allowed to tilt relative to the longitudinal axis of the mounting bracket in any radial direction therefrom. In other words, even while frictionally retained in the bushing in the axial direction, the pole 12 is free to pivot about two perpendicular axes, each lying normal to that the of the mounting bracket bore. The bushing provides resistance to this relative titling between the pole and headrest so that it doesn't feel too loose or wobbly, and the resilience of the rubber bushing also provides some shock absorption during use of the headrest. Under sufficient tilting out of the default concentric position into which the pole is biased by the resilient bushing, the pole will eventually come into contact with the peripheral wall of the mounting bracket's bore, which thus limits the attainable angular range of tilt a in any direction to a predetermined amount, which may for example be in order of 10-degrees to 15-degrees in some embodiments.

As a result of the resiliency of the rubber bushing 30′ and the empty upper portion of the mounting bracket bore that is left unoccupied by the bushing 30′ to provide clearance between the lower shaft section 12d and the inner wall of the mounting bracket 26′, the pole 12 is allowed to tilt relative to the longitudinal axis of the base plate mounting bracket in any radial direction therefrom. In other words, even while frictionally retained in the bushing in the axial direction, the pole 12 is free to pivot about two perpendicular axes, each lying normal to that the of the base plate mounting bracket 26′. The bushing provides resistance to this relative titling between the pole and base plate 14 so that the pole doesn't feel too loose or wobbly, and the resilience of the rubber bushing also contributes to the aforementioned shock absorption during use of the headrest. As described above for the headrest, under sufficient tilting out of the default concentric position into which the pole is biased by the resilient bushing, the pole will eventually come into contact with the peripheral wall of the mounting bracket's bore, which thus limits the attainable angular range of tilt in any direction to a predetermined amount. As for the headrest, the base plate's tilt limit relative to the pole 12 may be in order of 10-degrees to 15-degrees in some embodiments.
With reference to
When the headrest is in use, the rubber bushing allows the top-plate assembly to tilt slightly in all directions, but with a limited range, which again may be in the order of approximately 10 to 15 degrees, depending on the flexibility of the rubber bushing used and the selected clearance measurement between the centered position of the pole and the surrounding confines of the bracket. The tilting feature of the top-plate assembly allows the user to suit the angle of top-plate and pillow to the user's head height and body position. The easy-to-deploy telescoping support pole is height adjustable, allowing the user to find a precise height for the top-plate assembly, which best fits their particular body type and preference.
In one embodiment, ABS plastic is employed for the headrest plate, headrest mounting bracket, stabilizing base plate, base plate mounting bracket, and the pole is formed of lightweight aluminum pipe or tubing. The hard ABS top-plate ensures that there is enough resistance beneath the pillow for the user to find comfortable angles to position their head while resting on the device. The tethering straps may be made of nylon webbing or other flexible strap material, and aluminum carabiners may be employed to provide strong, but lightweight coupling members.
The tethering straps are used for added support and stability. The flexible tethered connection allows the device to be secured in many fashions. For example, the support straps can be secured together around the user's back, like a harness; clipped to pant pockets or belt loops of clothing worn by the user; fastened to the arms or bases of seats; fastened to seat-belts; or fastened to any structure which is rigidly secured in place in the passenger cabin of the vehicle concerned.
The forgoing device has been designed to support the head and upper body in a variety of situations, though its primary intended use is to assist with resting and sleeping while traveling on planes, trains, buses, and cars while seated. It has been designed to be light-weight, compact, and stable in operation; to occupy minimal space when deployed and be easily set up and subsequently packed away after use. Combined, these features make the device an ideal sleep-aid product for frequent travelers.
Particularly unique and advantageous features of the forgoing embodiments of the invention described above are briefly summarized as follows:
The stability straps provide additional and improved device stability, and are particularly useful when deployed in environments where the user may encounter turbulence or unexpected jarring movement. Some common examples might be when travelling on trains, airplanes, or cars, though this list is certainly not exhaustive.
The straps allow for the weight of the device to be counterbalanced by the user's upper torso weight, when the user is leaning forward with their head pushed against the top-plate assembly.
The straps prevent the device from falling over or slipping out from beneath the user when they are asleep, where self-movement is most likely to occur.
Device is constructed from durable, light-weight materials.
Adjustable telescoping pole allows the device to compact in size.
Device is easy to assemble and disassemble in confined spaces, and once assembled can easily be moved about, which minimizes disturbance to neighboring passengers and allows passage in confined spaces.
Top-plate assembly can be quickly and easily removed from the pole.
Compact pillow does not require a large volume of valuable luggage space.
Device and all components attach and detach easily.
Device can be packed away neatly into a compact travel case.
The lower base plate receives the end of the telescoping pole, and provides additional stability.
The rubber bushing which is found in both the upper and lower mounting brackets, not only provides flexibility, but also provides some shock-absorbing capacity. This would help to reduce vibrations at the top-plate assembly.
Turning to
The fixed bracket 50 features a flat mounting plate 52 with fastener holes 52a by which it can be fastened to the front edge of the seat frame or to another suitable support structure or object in the passenger cabin of the vehicle concerned. A pair of lugs 54 project perpendicularly from the mounting plate 52 in parallel vertical planes at horizontally spaced positions from one another. The mounting plate and lugs may be welded together, as shown at 56, and in one example, may be formed of stainless steel to provide suitable strength and resistance to corrosion, but it will be appreciated that other materials may alternatively be employed. A swivelling block 58 is pivotally suspended between the pair of lugs 54 by a pair of aligned pivot pins 60 each passing through a respective one of lugs to pivotally connect a respective side of the block 58 thereto, whereby the block 58 suspended between the two lugs can swivel about a horizontal axis shared by these pivot pins 60. The swivel block 58 has cylindrical bore therein, which, like that of the headrest mounting bracket 26, contains a cylindrical rubber bushing 30″ that resides at one end of the bore and occupies less than a full axial length thereof. The swivel block may be identical to either of the mounting blocks 26, 26′ described above for the embodiment of
Referring to
It will be appreciated that select features of the inventive headrest may employed in combination with, or independently of, one another. For example, the use of flexible tethers to allow connection of the headrest device to any of a variety of other objects for stabilization purposes, regardless of the particular environment in which the headrest is used, can be employed regardless of whether the same headrest device also employs the described multi-axis joint between the support pole and the headrest and/or base plate. Likewise, the swivelling bracket for fixed or permanent mounting solutions may be employed regardless of whether the connected headrest device features flexible tethers and/or multi-axis joints. The same headrest device may be used either with a removable base plate or a permanently mounted swivel bracket simply by inserting the bottom end of the pole into a selected one of either a compatible base plate or swivel bracket in cases where a simple friction fit connection allows such simple connection and detachment.
In embodiments that include a base plate, it may be circular, or any one of a number of possible other shapes. Although nylon straps have been found to be suitable stabilization tethers, other materials and other shapes could also be used, such as flexible cords, ropes, strings, or cables. It will also be appreciated that while use of ABS or other plastic of suitable strength has been described for the headrest and base plates, and the mounting brackets of the associated joints, in order to minimize the weight of the device, metals or other materials may alternatively be employed.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the scope of the claims without departure from such scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
