Adjustable pillow

Abstract

An adjustable pillow is designed for use by a user lying flat and on their side, and includes a central section and two side sections. The central section extends horizontally and is used for the user lying flat. The central section defines a first recess that tapers downwards in diameter for the user's head to rest in. The central section includes a first placement portion and two first abutment portions for the user's neck to rest against. The side sections extend horizontally and connect to both sides of the central section, and are used for the user lying on their side. Each side section defines a second recess that tapers downwards in diameter for the user's head to rest in. Each side section includes a second placement portion and two second abutment portions for the user's neck to rest against.

Claims

1. An adjustable pillow suitable for a user to lie flat and on their side, comprising: a central section extending in a horizontal direction for accommodating the user lying flat; a reference surface defining a perpendicular surface through the central section and dividing the central section equally; the central section defining a first recess that is recessed downwards with a tapering diameter relative to the reference surface for accommodating the user's head; the central section including a first placement portion located below the first recess; and two arc-shaped first supports spaced apart on both sides of the first placement portion in the horizontal direction and defining the first recess together with the first placement portion, for accommodating the user's neck. The backrest is defined by a first vertical height where the first placement part intersects with the reference surface, a horizontal plane parallel to the horizontal direction, and a first tangent line passing through one of the first backrest parts, the user's neck and back. The first tangent line has a first tangent point with the first backrest part. The vertical length from the first tangent point to the bottom surface of the central block is 2 to 2.5 times the first vertical height. The length of the bottom surface of the central block along the horizontal direction is 6 to 11 times the first vertical height. The diameter of the top of the first groove along the horizontal direction is 3 to 5 times the first vertical height. The system includes two side sections, made of a harder material than the central section, extending horizontally and connecting to both sides of the central section along the reference surface, for the user to lie on their side. Each side section defines a second recess that tapers downwards relative to the reference surface, for the user's head to rest in. Each side section includes a second placement portion located below the second recess, and two arc-shaped sections spaced apart horizontally on both sides of the second placement portion, which together define the second recess for the user to rest in. The second abutment portion rests against the neck, defining a second vertical height at which the second placement portion intersects the reference surface, and a second tangent point located at the junction of one of the second abutment portions and the user's neck and back. The second vertical height is greater than the first vertical height. The vertical length from the second tangent point to the bottom surface of the corresponding side block is 1 to 2 times the second vertical height. The length of the bottom surface of each side block along the horizontal direction is 3.5 to 7 times the second vertical height. The diameter of the top of the second groove along the horizontal direction is 2 to 3 times the second vertical height.

2. The adjustable pillow as claimed in claim 1 further includes an adjustment member having thickness that is detachably disposed below the central section and the side sections.

3. The adjustable pillow as described in claim 2, wherein, The adjustment member includes a pad portion disposed below the central block and the side blocks and defining an accommodating space, and an inflation portion communicating with the accommodating space and used to inflate the accommodating space.
