Abstract

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 to support the user's ischial tuberosity. The hardness of the seat layer is smaller than the hardness of the supporting portion. The present invention uses the seat layer made by the material with a good covering shape and can release user's upper body, hips and legs stress properties for a user to sit, and uses the hard supporting portion to support the user's ischial tuberosity, makes the weight of the user's upper body to be supported by the user's ischial tuberosity with transmits the stress uniformly to the seat layer and the supporting portion, thereby preventing the user has feeling about sore, ache, and pain from releasing the user's hips and legs stress.

Description

cushion

The present invention relates to a seat cushion, and more particularly to a seat cushion for straightening the spine, supporting the ischium, and uniformly releasing the upper body, the hips, and the leg pressure.

With the change of life style, many people must maintain their sitting posture for a long time to use computers, watch TV or work in the field. When the human body adopts the sitting posture while resting, meditating or working on the tabletop, the support of the seat cushion and the uniform pressure release function can reduce the pressure of the hips and the legs, thereby reducing the burden on the body and the heart, thereby reducing the energy consumed by the human body.

Furthermore, since the lumbar load of the human body mainly comes from the weight of the upper body, the amount of movement of the trunk and upper limbs, and any external force or weight applied thereto. Therefore, when the body is in a sitting position, if the sitting posture is not correct, the upper body weight distribution will be uneven, and the hunchback will not be able to effectively transmit the pressure to the seat cushion. The lumbar vertebrae and the trunk supporting the upper body weight of the human body are prone to damage, which in turn causes acid, numbness, swelling, pain, etc., and even the spirit is distracted and the concentration is not concentrated. The era of efficiency for modern people represents a waste of time.

Traditional cushions often have a comfortable cushion so that the user can effectively disperse the weight of the upper body when riding, and can support the body in a large area, so that the body is effortless. However, for a user who is riding for a long time, in order to enable the seat cushion to support the body in a large area, the user cannot effectively straighten the spine, and the spine is deformed and deformed, thereby pressing the vertebral body and The tailbone causes poor blood circulation and poor nerve conduction, thus causing symptoms such as acid, numbness, swelling, and pain, and it is also unable to achieve effective relaxation.

In the prior art, a seat cushion having a function of allowing the user to straighten the trunk is often required to be used with the seat, and a seat matching the shape and size of the seat cushion must be found to have its function. Although it has the effect of straightening the spine and not pressing the vertebral and caudal vertebrae, it cannot be used alone, thus causing inconvenience in use and causing regrets that the sitter cannot use it.

It can be seen that there are still many shortcomings in the above-mentioned conventional techniques, which is not a good design and needs to be improved. In view of this, the present invention will provide a seat cushion that can be used by ordinary daily and meditation people, and has a seat cushion that allows the user to naturally straighten the spine and avoid the effect of pressing the vertebral and tail bones.

One aspect of the invention is to provide a seat cushion. According to one embodiment of the invention, the seat cushion of the present invention includes a support portion and a carrier layer. The support portion is for supporting a user. The carrier layer is disposed on the support portion for carrying the user. Wherein the hardness of one of the carrier layers is less than the hardness of one of the support portions. In addition, the seat cushion of the present invention further includes a base for carrying the support portion and the carrier layer, the seat cushion being provided for the user to ride or lean against the waist and the neck.

Another aspect of the present invention is to provide a seat cushion that provides a user ride. According to another embodiment of the present invention, the present invention provides a seat cushion comprising a base, a carrier layer and a support portion. The carrier layer is placed on the base to provide a user ride. The support portion is disposed between the base and the carrier layer to support the user's ischium to prevent the vertebral and tailbone from being compressed. Wherein, the hardness of the carrier layer is less than the hardness of the support portion.

The width of the support portion is greater than the distance between the two ischiets of the user; the width of the ride layer is greater than the width of the user's buttocks.

The support portion includes a central pressure release portion and a support ring. The central pressure release portion is disposed in the support ring, and the ischial bone is supported by the support ring, and the hardness of the central pressure release portion is smaller than the hardness of the support ring. The width of the central pressure relief portion is less than the distance between the two ischial bones of the user.

In still another embodiment of the present invention, the present invention provides a seat cushion including a base, a support layer, and a carrier layer. The support layer is disposed on the base, and includes a support portion and a pressure release auxiliary portion. The support portion supports the user's ischium. The pressure relief auxiliary portion has a central hole, and the support portion is disposed in the central hole. The carrier layer is disposed on the support layer to provide a user ride. Wherein, the hardness of the carrier layer is less than the hardness of the support portion.

The width of the support portion is greater than the distance between the two ischiets of the user; the width of the ride layer is greater than the width of the user's buttocks.

The support portion includes a central pressure release portion and a support ring. The central pressure release portion is disposed in the support ring, and the ischial bone is supported by the support ring, and the hardness of the central pressure release portion is smaller than the hardness of the support ring. The width of the central pressure relief portion is less than the distance between the two ischial bones of the user.

In general, in the seat cushion of the present invention, the carrier layer provides a soft, overall uniform pressure release and a good covering property for the user to ride, while supporting the user's ischium with a hard support portion to support the upper body. Partial weight and overall uniform pressure release, to avoid partial pressure on the hips and legs and hinder the smooth flow of nerves and blood, causing acid, numbness, swelling and pain.
