CUSHION
The present invention discloses a cushion for providing a user to sit on. The cushion includes a base layer, a seat layer and a supporting portion. The seat layer is configured on the base layer for providing the user to sit on. The supporting portion is configured between the base layer and the seat layer for supporting the user's ischial tuberosity. The seat layer is made with the material of the good covering shape, thus it can release user's upper body, hips and legs. Furthermore, by using the hard supporting portion for supporting the user's ischial tuberosities, the cushion makes the weight of the user's upper body be transmitted uniformly to the seat layer. Therefore, the cushion can prevent the user's hips and legs from some physical pains such as sore, ache, and pain due to long period of partial stress.
The present invention relates to a cushion, more particularly, to a cushion for making the user's spine straight, supporting ischial tuberosity, and releasing user's upper body, hips, and legs stress.
2. Description of the Prior ArtDue to the development of modern life, many people in modern times have to work in a way of remaining sitting for a great length of time. In many situations, such as resting, meditation, or work with the desktop, people are used to utilizing cushions to provide increased support and comfort. Due to the cushion's effect on supporting and pressure-releasing, the user's upper body, hips, and legs can be released and thus the energy consumption of human body can be reduced.
Furthermore, it is known that human lumbar spine's load comes mainly from the weight of the upper body, upper limb movements, and other external force or weight applied thereto. As long as the body is not sitting in a straight posture, the upper body's weight will be dispersed unevenly and thus leads to hump so that the pressure cannot be effectively passed to the cushion. Partial pressure from upper body leads to damage on lumbar spine and causes physical pains such as sore, ache, and pain. The irritation and pain further lead to the spirit of lax, inattention, which means a waste of time in the modern era of efficiency.
The conventional cushion used to be in good effect on cushioning good covering shape for dispersing the weight of the user's upper body. However, the user cannot effectively straighten the spine for a long period of time and thus causes spine's distortions. The spine will be in a distortion state, and the force on the sacral vertebrae and coccyx causes poor blood circulation and slow nerve conduction, which results in irritation or pain.
In conventional technique, the cushion used to be in pairs with a seat in order to straighten the user's trunk, and the seat's shape and size must match the cushion. In spite of the conventional technique cushion's effect on straightening the user's spine and preventing sacral vertebrae and coccyx from compression, the cushion cannot be used alone, which results in not only the use of inconvenience but also the unavailability for the mediators.
Thus, the above-mentioned technology still has many disadvantages, and it is not a good design. Therefore, it needs to be improved. In conclusion, the present invention provides a cushion for daily normal usage or for meditation. The cushion enables a user to achieve a spine naturally straight posture with comfort in order to prevent the user's sacral vertebrae and coccyx from compression.
