Definitions

• the present invention focuses on improvement of head-support function of pillows and chairs; it is intended to enhance the convenience for everyday use with application of ergonomic figure, proper utilization of materials and advanced structure.
• the cervical vertebrae consists of seven bones around neck area and joins skeleton to the spine. It looks a curve having a "C" shape of c in a sectional view. It plays an important role of sustaining head and regarded as one of the most important and delicate part of human body because spinal cord (assembled group of various neurons) penetrates through this cervical vertebrae.
• the human cervical vertebrae has a 'C shaped curve when standing straight, while it floats in the air when lying down on the bed or leaning against the chair. When sleeping in the chair, it is also wrenched and tilted to the left/right or forward/backward due to the relaxation of neck-muscle as well as round-shape of back of the head.
• the meaning of natural head-fix(place) is to insert head deeply into 'ergonomic shape hole.
• the main concept of this invention is to use the method of head- fix and head- support in stable and comfortable manner on pillows and chairs by comprising deep 'ergonomic shape hole of head-insert' that copies the back shape of head and neck.
• the present invention is to add 'ergonomic shape hole of head-insert' to the pillow/ headrest combined with applicable objects (such as pillows, chairs and sofas). For its proper usage, it should be remodeled by the concept of combining the pillow/headrest with applicable objects. For its multipurpose and compatibility, the joint-dimension between applicable objects and the pillow/headrest is unified and standardized. Also, its portability will be increased by minimizing the size and weight of the pillow/ headrest. Accordingly, this invention furnishes more comfortable way of living by facilitating the multi-use of the product.
• the pillow/headrest can be utilized for variety of environments; bedrooms, sofas, reclining chairs and office head-back chairs and also for outdoor places such as camping zones and picnic areas, including passenger seats of airplanes, ships, trains, buses, automobiles.
• the purpose of this invention is to maintain the best comfort position of head and neck in any circumstances and environments.
• the technological conditions are as follows:
• the pillow/headrest should be combined with and separated from the body of applicable objects easily and simply for the effective usage.
• the external size should be standardized (expected to be about 26-28 centimeters width) for properly compatible use with all kinds of applicable objects in any time. It also provides adjustment function of pillow/headrest position according to the user's sitting head height.
• the chairs can not be reclined backward enough and need various aids function of keeping comfortable posture of head by supplements because the interval space of equipped chairs in long-distance transportations such as airplane, ship, train and bus is narrow.
• existing chairs have only flat ground and a part of jutted component near by both sides of head for simply avoiding the head's movement, instead of providing ergonomic shape insert hole on the head part of chair body where human head is placed.
• this kind chairs can not release pains and stress of neck and shoulder mainly because it has not improved support function for head and cervical vertebra without providing essential solution to the wrenched neck.
• This present invention can provide solution to long standing problem by adding the deep 'ergonomic shape hole of head- insert' and by remodeling the chair body for assembly of 'pillow/headrest', which has not been tried for chairs yet (Fig. X).
• Embodiment of figure for 'ergonomic shape hole of head- insert' is required in advance of commercialization and manufacturing of 'forming of head shape- hole'(called 'pillow/headrest' after this).
• Embodied figure looks after the 'shape of half- sphere'(drawing code 1) like the back of human head and the 'shape of half-cylinder' (drawing code 2) like the back of human neck as Fig.l & Fig.3.
• the application idea of combined figure with 'shape of half- sphere' and 'shape of half-cylinder' for pillows and chairs is a simple concept as 'the egg of columbus' but practically there has not been any instances to apply such ideas to pillows and chairs so far.
• the first method is 'forming & expansion molding system' with materials of latex- form, memory-form and sponge. It is a normal production method with existing skills, which does not seem difficult to proceed the production of this invention.
• the second method is 'drilling cutting system' which uses a drilling machine
• basis forming products is drilled for making 'ergonomic shape hole of head-insert' and is cut for size of height and each piece one by one moving along the conveyor belt.
• hole of air- flow can be made on pillow/headrest by drilling of small diameter as much as necessary.
• Latex-form, memory-form and sponge are used for manufacture of pillow (but memory-form is excepted for main pillow in bed especially due to easy variation according to the temperature, for example, distorted by weight of human head in warm temperature and hard hand- feel in cold temperature).
• Latex-form, memory-form are used for headrest function of sofa and chairs. (Sponge is excepted due to poor hand- feel)
• 'extension model' (code 4 of Fig. 4) are manufactured one by one as separated structure instead of all-in-one and are inter-combined automatically by exterior shell during the usage. Later they can be divided after opening the zipper and exterior shell can be removed for washing.
• Some exceptional height and external size of 'basic & extension model' of 'pillow/headrest' can be adjusted in various according to special requests during the process of production. For some cases, size of 'basic model' can be enlarged without 'extension model' for following of wide requirement of consumers.
• 'ear recess' (drawing code 5 of Fig. 4) is provided for comfortable sleeping without crooking of ear during side turning of body and face. We often move body when sleeping if we do not feel comfortable on our head and neck but we enjoy deep sound sleep for long period of time in straight posture with little movement, if head and neck are in comfortable condition.
• [50] - Extension model (code 4 of Fig. 4) : this area is used during body movement to right and left, and may be useful in relieving pain of neck and shoulder because height of 'extension model' is close to height of shoulder.
• the pillow of 'standard model' of pillow/headrest' (drawing code 3) can be used under back of the neck/head in normal way and the height of pillow can be adjusted with attached 'triangle shape panel' (drawing code 34 of Fig.7) with a velcro tape (drawing code 35 of Fig.7), if necessary.
• 'Standard model' of 'pillow/headrest' (drawing code 3) can be used under neck and head when we sleep or rest on existing reclining chair and automobile seats after reclining backward. If necessary, 'triangle shape panel' can be used for adjustment of height of 'pillow/headrest'
• the drawing code 'b' indicating the length of 'pillow/ headrest', is adjustable portion of 18 to 20cm depending on the applicable objects and sometimes, on circumstances.
• the drawing code 'c' indicating the height of 'pillow/headrest', categorizes the size of 'ergonomic shape hole of head- insert' into the size group of S/M/L that is classified based on survey of standardized head size. Exceptionally for bedroom pillows, the height and external size can be changed under the adjustment of production procedure as per consumer requirement.
• This installation method of 'pillow/headrest' on chair body is an indirect insert method using box-shaped 'aid frame' components (drawing code 9 of Fig. 12).
• This 'aid frame' can install 'pillow/headrest' and is inserted into the 'square shape insert hole' of chair body.
• Metal or strong synthetic resin will be used as its material and the size of 'aid frame'(drawing code 12) will be less than 'pillow/headrest' so that it should not touch the human head when sitting on chair.
• Insert pole' (drawing code 8) is inserted into 'hole' of tube shape (drawing code 13) for assembly and position adjustment of 'pillow/headrest' with chair body. This method can be used for new production only and for seats of trains and buses due to the low risk of theft.

• 'ergonomic shape hole of head-insert' should be produced in three size groups of S/M/L based on survey on standard size of human head ( For bedroom pillows, production may be separately made for infants and children, if necessary).
• cutting knife (drawing code 18 of Fig. 13) can be used for classification of 'ergonomic shape hole of head-insert' into the size group of 'S/M/L' in 'drilling cutting system' as shown in drawing code 19 of Fig. 13.
• the concept of dimension resolution for 'ergonomic shape hole of head-insert' is based on the fact that centre of gravity of human head and neck is placed on one point as shown in Fig. 19.
• the insert hole size for head and neck are fixed according to the same diameter (estimated to be 20CM for head and 14CM for neck) and to each different circle length of S/M/L size group.
• size of 'ergonomic shape hole of head-insert' varies according to the size group of S/M/L under the principle that the bigger the size of head is, the thicker the width of the neck is (drawing code 40 for size 'L' , drawing code 39 for size 'S').
• Bigger head size means longer length of head circle and high cutting position (drawing code 42 & 43 of Fig. 19) by placing closer to the centre of circle because the length of circle varies according to the cutting position of circle instead of difference in diameter.
• the height of "pillow/headrest' is fixed naturally at size groups of S/M/L.
• diameter of drilling tool should change according to the size of
• one size mold can produce necessary size selectively among whole size group of S/M/L depends on necessity of different size by adjustment of mold inside-unit, of course although it can proceed different diameter of drilling tool and different diameter of mold for each size group of S/M/L in general way.
• [164] - cutting hole type it provides accurate 'square shape insert hole' on body of chair for assembly with 'pillow/headrest'. And 'square shape insert hole' is covered with same exterior shell fabrics as chair body (such as synthetic leather, textured fabrics, etc), it is basic method and is suitable for only new production of chair (drawing code 41 of Fig. 10 and Fig. 12)
• [165] - Tray insert type It adds the 'aid component tray-insert' (drawing code 20 of Fig. 14) to 'square shape insert hole'. It is useful for both new production of chairs and recycling of existing chairs.
• 'Aid component tray-insert' as one type of plastic injection molding products with the shape of tray, plays a role as a linking-device between '"pillow /headrest' and chair body. (Refer to Fig. 14). More details will be specified in next column, as this is one of the most important items in this invention.
• drawing code 22 of Fig. 17 to the head part of chair body (drawing code 21 of Fig. 17), made by the 'injection molding' system or 'forming expansion molding' system with synthetic resin of somewhat harder material than sponge to preserve the shape of chair without affecting the soft hand-feel.
• it can be covered with special fabrics. It is particularly useful for new production of chairs. It can also be combined with chair body as method of poll- insert (drawing code 32 of Fig. 17). For the low/high position adjustment of 'pillow/headrest', it adopts type A
• [167] 2) Direct type For more another type of chair, it provides an 'ergonomic shape hole of head- insert' on head part of chair body (drawing code 24 of Fig. 18) directly by 'forming expansion molding' system or 'drilling cutting' system with materials of latex- form, memory-form and sponge. It is useful for new production of chair. For function of both low/high position adjustment and assembly with chair body, it adopts 'aid frame' enlarging type B (drawing code 33 of Fig. 18).
• the aims of this invention are to reinforce (i)the assembly function and compatibility (ii) the efficiency and neat look of remodeled chair (iii) the adjustment function of tray-insert's depth (height), (iv) the locking of 'tray-insert' on chair body, (v) the low/high position adjustment function of 'pillow/ headrest'.
• border piece which is just depth/height of 'tray-insert', can be made in each requested size as one piece (without separation of bottom and border), and also can be controlled by combination and separation of injection mold inside.
• general method need many injection molds for production of 'tray-insert' on high cost and within limited process, while this invention can produce many kinds of 'tray-insert' of different depth/height because it combines bottom piece (drawing code 29 of Fig. 16) together with many kinds of border piece which is cut as per requested size of depth/height after injecting one kind deepest/highest size of border piece. Remainder pieces can be used for next injection production to save wasted materials.
