Description

  The present invention relates to a pillow for forming a right tilted supine position in which a user can easily form a right tilted supine position with little physical load.

  Pillows are used when sleeping on futons. The pillow rests your head when you lie down. Conventional pillows generally have a main purpose of sleeping with their heads facing upward, that is, forming a so-called supine position. For this reason, when a normal pillow is used, the user is in a supine position at bedtime. However, the supine position is not always a good sleeping position depending on the physical condition of the user. In addition, when sleeping, it sometimes turns into a recumbent position because it turns over. Depending on the combination of these positions and the user's physical condition, the user may not be able to sleep comfortably. In addition, it is said that blood pressure is slightly higher in a supine sleeping that maintains a normal horizontal position than in a standing position.

  Many pillows have been proposed, for example, JP-A-2006-198210 (Patent Document 1). In this document, a side-by-side pillow that can be semi-forcedly returned to the lateral position even when the body is placed in the supine position by sleeping by attaching the pillow body so as to sandwich the head is proposed.

Japanese Patent Laid-Open No. 2001-112599 (Patent Document 2) discloses that a gap generated in a part of the body that is curved or deformed when lying on its side is closed to relax the tension of the pectoral muscles and facilitate the respiratory movement of the chest. There has been proposed a posture-stabilizing pillow that makes it possible for an elderly person or a long-term care person who is curved or the like to be in a supine position and is adjusted according to the body shape.
Furthermore, in the registered utility model No. 3025484 (Patent Document 3), the cervical vertebrae is supported in the supine position, the occipital region is stably stored, and the temporal and cervical vertebrae are supported in the lying position. A pillow for lying on the back and lying down that can maintain the sleeping posture of the child has been proposed.
