Description

Ergonomic pillow The present invention mainly discloses an ergonomic pillow, especially an ergonomic pillow that can provide good comfort. Please refer to Chinese Patent No. M646539, "Pillow," which is a pillow comprising a supine support part, a chest and neck support part, and two side-lying support parts. The supine support part has a concave arc segment extending in a front-back direction, and a concave arc-shaped fitting groove is formed at the center of the concave arc segment. The chest and neck support part extends forward from the middle section of the supine support part, and the two side-lying support parts are respectively formed on the left and right sides of the supine support part. However, the support provided by the aforementioned pillows or other traditional pillows is limited to the user's head and neck area. The difference in height between the pillow and the mattress will result in a lack of support for the area below the cervical spine, preventing proper relaxation. In view of the shortcomings of the above-mentioned conventional structures, the inventors have designed an ergonomic pillow that can overcome all the disadvantages of the above-mentioned conventional structures. The main objective of this ergonomic pillow is to provide an ergonomic pillow comprising a pillow body. The pillow body has a headrest portion, a neck portion, a back portion, and two recesses along its vertical upper edge surface. The headrest portion supports the user's head and has a first width extending from left to right. One end of the neck portion is connected to the headrest portion, and the neck portion has a second width extending from left to right. The back portion is connected to the end of the neck portion opposite to the headrest portion and supports the user's back. The back portion has a third width extending from left to right. The two recesses are respectively located on the left and right sides of the neck portion, such that the second width is smaller than the first and third widths. This ergonomic pillow provides excellent comfort through its structure. The pillow body has a bottom surface along its upper vertical edge, and the headrest has a lying area adjacent to the neck. The distance from the end of the lying area near the neck to the bottom surface forms a first height, and the distance from the end of the lying area opposite to the neck to the bottom surface forms a second height, which is less than the first height. The distance from one end of the back adjacent to the neck to the bottom surface forms a third height, which is less than the first height. The distance from one end of the back opposite to the neck to the bottom surface forms a fourth height, which is less than the third height. The headrest is provided with two side-lying areas, which are respectively located on the left and right sides of the flat-lying area and adjacent to the two recesses. The distance from the end of the side-lying area near the neck to the bottom surface forms a fifth height, which is greater than the third height. The distance from the opposite end of the side-lying area to the bottom surface forms a sixth height, which is greater than the fifth height. The back can elastically deform between a contracted state and an extended state. In the contracted state, the distance from the end of the back adjacent to the neck to the opposite end of the back forms a first length. In the extended state, the distance from the end of the back adjacent to the neck to the opposite end of the back forms a second length, which is greater than the first length. The back panel has several expansion joints, several left side joints, and several right side joints. These expansion joints, left side joints, and right side joints are all elongated and connect the surface and bottom of the back panel. The expansion joints extend along the left-right direction of the back panel. The left side joints are connected to the left side of the back panel and extend towards the right side of the back panel. The right side joints are connected to the right side of the back panel and extend towards the left side of the back panel. When the back panel is in an extended state, the expansion joints, left side joints, and right side joints are stretched and unfolded. When the back panel is in a contracted state, the expansion joints, left side joints, and right side joints return to their elongated shape. Other objects, advantages, and novelty of the invention will become more apparent from the following detailed description and the accompanying drawings. 10: Ergonomic pillow 20: Pillow body 21: Back of head 211: Flat-lying area 212: Side-lying area 22: Neck 23: Back 231: Expansion joint 232: Left side seam 233: Right side seam 24: concave part 25: Bottom H1: First Height H2: Second Altitude H3: Third Height H4: Fourth Height H5: Fifth Height H6: Sixth Height L1: First Length L2: Second Length LH: Head Length W1: First width W2: Second width W3: Third width Figure 1: A three-dimensional view of the ergonomic pillow of the present invention.
