Description

  The present invention relates to a cushion, and more particularly to a cushion for straightening a user's spine, supporting ischial tuberosities, and releasing stress on the upper body, buttocks and legs of the user.

  As modern life has progressed, many modern people have to work sitting for quite a while. People are used to using cushions to enhance support and comfort, in many situations such as resting, meditation, or working on a desktop computer. Due to the cushioning effect on the support and the pressure release, the stress on the upper body, buttocks and legs of the user can be released and consequently the energy consumption of the human body can be reduced.

  Furthermore, it is known that the load on the human lumbar spine comes mainly from the weight of the upper body, the movements of the upper limbs, and other external forces or weights applied to them. As long as the body is not sitting in a straight-up posture, the weight of the upper body is unevenly distributed, resulting in curling of the spine so that pressure can not be effectively transferred to the cushion. Partial pressure from the upper body causes damage to the lumbar spine and causes physical pain such as pain, pain, and pain. Stimulus and pain are mental neglect and carelessness, that is, in the modern era, it is a waste of time.

  Conventional cushions are said to be effective by providing a cushion with a good covering shape to disperse the weight of the upper body of the user. However, the user has not been able to straighten the spine effectively for a long time, resulting in distortion of the spine. The spine becomes distorted, and the force on the sacral vertebrae and tail bone causes poor circulation and reduced nerve conduction, resulting in irritation and pain.

  In the prior art, the cushion is paired with the seat to straighten the trunk of the user, and the shape and size of the seat must match the cushion. Despite the prior art cushioning effect of straightening the user's spine and preventing compression of the sacral vertebrae and coccyx, the cushion can not be used alone, and as a result it is not only difficult to use but also for meditators It can not be used for

  Thus, the above techniques still have many drawbacks and are not good designs. Therefore, it needs to be improved. In conclusion, the present invention provides a cushion for everyday use or for meditation. The cushion allows the user to comfortably take a natural straight posture of the spine in order to prevent compression of the user's sacral vertebrae and coccyx.

  Therefore, the inventor who has been engaged in manufacturing and developing related products for many years and has design experience has made a detailed design of the present invention and carefully evaluated and finally confirmed that it can actually be used. .

  The main object of the present invention is to provide a cushion. According to one embodiment of the invention, the cushion comprises a support and a seat layer. The support is used to support the user. The sheet layer is formed on a support that supports the user, and the hardness of the sheet layer is lower than the hardness of the support. Further, the cushion of the present invention includes a base layer that supports the support portion and the seat layer, and the cushion is used when the user's waist, back or neck leans.

  Another object of the invention is to provide a cushion for use by the user when sitting. According to another embodiment of the invention, the cushion comprises a base layer, a seat layer and a support. The seat layer is formed on the base layer for the user to sit down. The support is formed between the base layer and the sheet layer to not only support the ischial tuberosity of the user but also to prevent compression of the sacral spine and coccyx. The hardness of the sheet layer is less than the hardness of the support.

  The width of the support is wider than the distance between the user's two ischial tuberosities, and the width of the seat layer is wider than the width of the user's buttocks.

  The support comprises a central pressure release and a support ring, the central pressure release being provided in the support ring, the user's ischial tubercle being supported by the support ring, the hardness of the central pressure release being that of the support ring Lower than hardness. The width of the central pressure opening is less than the distance between the user's two ischial tubers.

  According to another embodiment of the invention, the cushion comprises a base layer, a support layer, and a sheet layer. The support layer is formed on the base layer and includes a support and a pressure relief aid. The support is used to support the ischial tuberosity of the user, the pressure relief aid has a central bore and the support is provided in the central bore. The seat layer is formed on the support layer for the user to sit down. The hardness of the sheet layer is less than the hardness of the support.

  The width of the support is wider than the distance between the user's two ischial tuberosities, and the width of the seat layer is wider than the width of the user's buttocks.

  The support comprises a central pressure release and a support ring, the central pressure release being provided in the support ring, the user's ischial tubercle being supported by the support ring, the hardness of the central pressure release being that of the support ring Lower than hardness. The width of the central pressure opening is less than the distance between the user's two ischial tubers.

  In conclusion, the seat layer of the cushion of the present invention is soft and even cushioning, providing a good covering shape for the user to sit on. In addition, most of the weight of the user's upper body can be transmitted through the user's ischial tubercle, and pressure can be evenly released by the rigid support. To that end, the cushion can prevent the user's buttocks and legs from doing some of the physical pain, such as pain, pain, pain, etc. due to partial stress, especially for a long time on a person meditating or sitting.
