Description

Cushion with a Honeycomb Structure The following embodiment relates to a cushion having a honeycomb structure. Generally, cushions are intended to provide comfort for sitting or leaning, and can be placed on or inside seats, chairs, beds, etc. Cotton cushions absorb shock and provide users with a comfortable seating experience. However, cotton cushions require a large amount of cotton to provide a good seating experience, and there is a problem where the comfort level easily deteriorates as the thickness decreases with use. Furthermore, there is also the problem of reduced breathability. To compensate for this, cushions containing elastic materials such as rubber and polyethylene have been proposed. Cushions containing such materials can also prevent slipping by providing sufficient friction. However, due to the characteristics of the materials, such cushions may have the disadvantage of reducing seating comfort and being heavier than cushions made of cotton. The aforementioned background technology is one that the inventor possessed or acquired in the process of deriving the contents of the disclosure of the present application, and it cannot be considered as prior art disclosed to the general public prior to the filing of this application. FIG. 1 is a perspective view of a cushion having a honeycomb structure according to one embodiment. FIG. 2 is a plan view of a cushion having a honeycomb structure according to one embodiment. FIG. 3 is a plan view of a cushion having a honeycomb structure according to one embodiment, which is an enlarged view of I in FIG. 2. FIG. 4 is a perspective view of a rib formed in a through hole according to one embodiment. FIG. 5 is a cross-sectional view of a bulkhead according to one embodiment, obtained along A-A' in FIG. 3. FIG. 6 is a cross-sectional view of a bulkhead according to one embodiment, obtained along B-B' in FIG. 3. Hereinafter, embodiments are described in detail with reference to the attached drawings. However, various modifications may be made to the embodiments, and thus the scope of the patent application is not limited or restricted by these embodiments. It should be understood that all modifications, equivalents, and substitutions to the embodiments are included within the scope of the rights.
