Description

  The present invention relates to a cushion that can be attached to and detached from a chair and a waist.

  Conventionally, various cushions for preventing back pain when sitting on a chair have been devised.

  For example, in Patent Document 1 (Japanese Patent No. 5466332), the object is to “provide a cushion for preventing back pain that can be easily attached and detached not only to car seats and office chairs but also to chairs of various designs”. A cushion for preventing back pain has been proposed.

  More specifically, “a back pain prevention cushion having a back support body and a lower back cushion body, wherein the upper end portion of the back support body forms a ring structure by an engaging and disengaging engagement piece. A lower end portion of the back support body is provided with a locking portion for locking a back surface portion of the lower end portion to the back surface portion of the back support body, and the waist cushion body is provided in the back support body with the waist portion. The above-mentioned cushion for preventing low back pain is proposed, which includes a connecting portion that enables the cushion body to move and connects the waist cushion body to the back support.

  Further, for example, Patent Document 2 (Japanese Patent Application Laid-Open No. 2011-218008) proposes an air cushion for the purpose of “providing an air cushion capable of correcting the right / left inclination of the human body”.

  More specifically, “flattened from the flat shape to the thickness direction by being filled with the gas through the gas introduction / exhaust portion that is arranged in parallel in the left-right direction and introduces or exhausts the gas provided in each of the support portions. An air cushion having a right side support part and a left side support part that support the vicinity of the buttocks and thighs of a seated person has been proposed.
