Multipurpose & compatible pillow/headrest

Abstract

This invention with improvements in external figure and structure based on new and different concept for pillow and chairs is intended to create practical convenience in daily life and to minimize the neck and shoulder pain created from usage of uncomfortable pillows in bed and inconvenient chair during long-distance travel. In an aspect of external figure, the invention adopts the concept of ‘ergonomic shape hole of head-insert’ which they never tried so far. As for the structure, this invention provides insert space hole on the body of applicable objects which ‘pillow / headrest’ (it has an ‘ergonomic shape hole of head-insert’) combines with, for easy process of assembly and separation between body and pillow / headrest. Additionally it is designed to maximize the portability and to accommodate the multiple usage by unifying the shape and size of ‘pillow / headrest.’ This invention promotes the convenience and practicality for everyday use of the pillow and chair. Applicable objects are: 1) bed pillows for sleeping on and pillows for leaning 2) portable pillows in outdoor camping area 3) head cushions on existing reclining chairs 4) headrest on passenger seats of long distance transportations including airplane, ship, train, bus 5) headrest on office chairs and reclining chairs 6) headrest on drivers' seats and assistant drivers' seats of automobile during rest and sleeping after reclining backward 7) headrest function of back seats of the car 8) headrest on sofas In particular, they can reuse the existing chairs by simply remodeling the product; this will be a valuable attempt to benefit both in economic aspects (saving natural resources) and eventually to increase the convenience of customers.

Description

TECHNICAL FIELD[0001]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.aa) Concept of Ergonomic Figure[0002]Among human spinal column, 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-...

AI Technical Summary

Benefits of technology

[0063]1) For sleeping and watching TV in bed (using it as main and aid pillow)

[0064]2) For sleeping in outdoor camping areas (hand-carrying in rucksack and separating from pillow / headrest’-installed back seat of private car)

[0065]3) For sleeping on passenger's seat of long distance transportations such as airplanes, ships, trains and buses

[0066]4) For relaxing and sleeping on reclining chairs and office chairs with head-back support

[0067]5) For relaxing and sleeping on sofa or on back seat of automobile

[0068]6) For relaxing and sleeping on driver's seat of private car after reclining backward (simply by laying the neck and the head on ‘pillow / headrest’. Existing driver's seats are not suitable to relax on or sleep on due to the uncomfortable shape and hard texture).

Problems solved by technology

It is not easy for human head and neck to be fixed straight and comfortable on flat ground and hard surface of pillow because the human head is round-shape.

Another example is modern pillows filled with materials of normal sponge, padding and midair-yarn; while it has soft texture, it is difficult to fix the head in a stable manner and we tilt our head left / right or forward eventually creates pain in neck and shoulder.

Recently, latex-form and memory-form have been used for pillows to provide solution to problems of tilted head and wrenched-neck, it has been improved much but not solved completely.

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.

Thus 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.

Somebody may worry if deep hole of ‘ergonomic shape of head-insert’ would give any inconvenience when sat on chairs.

However, it now became comparatively easier to implement this into variety of products due to the advance in technology, nobody has tried it until present.
