The present invention relates to a foldable seat cushion for effective correction of a user's poor posture, carrying and storage with ease owing to its small volume in a folded state.
A person staying at home or working in an office usually sits on a chair with poor posture for a long time, which possibly leads to a range of adverse health effects. If siting on a chair with poor posture for a long time, it will put people at a higher risk of developing and causing low back pain, lower limb numbness and permanent health issues such as spine flexion and kyphosis. In addition, a conventional chair cushion is usually made of foam material stuffed within a surface cloth to improve comfort while sitting. However, body heat of a user is diffused to and absorbed by the foam material within the surface cloth and is not easily dissipated. Therefore, the user will feel hot, stuffy and uncomfortable after sitting on the chair for a period of time.
The present invention discloses a foldable seat cushion for effective correction of a user's poor posture as well as improvement on health issues, such as spine flexion and kyphosis caused by poor posture. The present invention is also easy to carry and store due to its small volume after being folded. In addition, the present invention also prevents the user from lower limb numbness and feeling hot and stuffy.
The foldable seat cushion of the present invention comprises a first cushion body, a second cushion body, at least one third cushion body and at least one folding member. The first cushion body is disposed at a front region of the foldable seat cushion, the second cushion body is disposed at a back region of the foldable seat cushion opposite to the first cushion body, and the at least one third cushion body is disposed at each of two lateral regions of the foldable seat cushion and between the first cushion body and the second cushion body. The at least one third cushion body is connected to the first cushion body and the second cushion body by the at least one folding member. In addition, the second cushion body has a lower spine supporting portion. Accordingly, when a user is sitting on the foldable seat cushion of the present invention, the spine including the sacrum of the user is supported by the lower spine supporting portion of the second cushion body which straightens the spine of the user naturally. Therefore, the user has a correct sitting position by using the present invention so as to prevent low back pain and health issues such as spine flexion and kyphosis. Furthermore, the at least one third cushion body and the first cushion body can be sequentially folded and disposed under the second cushion body for storage when the present invention is not in use, so the effects of saving space, carrying and storing with ease are achieved.
First, the words “front” and “back” in the description of the present invention are used for describing the specific structure of the present invention more clearly and are not used to limit the direction of the present invention.
Referring to
The at least one third cushion body (3) is disposed at each of the two lateral regions of the present invention for connecting the first cushion body (1) and the second cushion body (2), and a hollow area (5) is defined by the first cushion body (1), the second cushion body (2) and the at least one third cushion body (3). In a preferred embodiment of the present invention, two of the third cushion bodies (3) are disposed at each of the two lateral regions of the present invention, and the two third cushion bodies (3) are connected by a folding member (4). The two third cushion bodies (3) have a symmetric shape with respect to an axis (X) of each of the two lateral regions where the at least one folding member (4) is located.
In addition, each of the first cushion body (1), the second cushion body (2) and the at least one third cushion body (3) has a soft pad (6) on a top thereof, and the soft pad (6) is made of a rubber material or a silicone material. Each of the first cushion body (1) and the at least one third cushion body (3) is provided with at least one first through hole (7), and each of the soft pads (6) on the first cushion body (1) and the at least one third cushion body (3) is provided with at least one second through hole (61) corresponding to the at least one first through hole (7). The second through hole (61) has a larger diameter than the first through hole (7) has. The present invention further comprises at least one massage element (8). The at least one massage element (8) is inserted into the at least one first through hole (7) of the first cushion body (1) and the at least one third cushion body (3) respectively. Each of the at least one massage element (8) has a block (81) at a top thereof protruding from the first though hole (7) and the second through hole (61).
Referring to
Furthermore, the user's lower limbs including the thigh are pressed on the block (81) of the at least one massage element (8) protruding from the first cushion body (1) and the at least one third cushion body (3) when sitting on the present invention in which the user's lower limbs are massaged by the at least one massage element (8). So the present invention also prevents the user from lower limb numbness. The soft pads (6) disposed on the first cushion body (1), the second cushion body (2) and the at least one third cushion body (3) can improve comfortability of the user sitting on the present invention. In addition, the user's hip and thighs are also insulated by the present invention from the chair seat (91) of the chair (9) to prevent diffusing of the user's body heat to a foam material within the chair seat (91) directly. Then, the user's body heat is not adsorbed by the foam material so as to decrease a hot and stuffy feeling caused by the body heat. The user's body heat is dissipated by the hollow area (5) defined by the first cushion body (1), the second cushion body (2) and the at least one third cushion body (3). The user's body heat is also dissipated by plural gaps at the connection regions of the first cushion body (1), the second cushion body (2) and the at least one third cushion body (3). Therefore, the present invention increases coolness and comfortability to the user sitting thereon.

According to the embodiments above, the present invention has advantages as follows:
1. The second cushion body of the present invention has a lower is spine supporting portion gradually inclined upwardly from a first side to a second side of the second cushion body which supports the sacrum of the user sitting thereon and straightens the spine of the user naturally. So the user has a correct sitting position by using the present invention so as to prevent low back pain and health issues such as spine flexion and kyphosis.
2. The foldable seat cushion of the present invention comprises at least one massage element which is inserted into the at least one first through hole of each of the first cushion body and the at least one third cushion body randomly as needed. The user's thighs are pressed on and massaged by the massage element when sitting on the present invention to avoid limb numbness caused by sitting for a long time.
3. The first cushion body, the second cushion body and the at least one third cushion body of the foldable seat cushion of the present invention are connected by a folding member, and the at least one third cushion body and the first cushion body can be folded under the second cushion body when the present invention is not in use. So the present invention achieves effects of saving space, carrying and storing with ease.
4. The foldable seat cushion of the present invention is laid on the chair seat of the chair and insulates the user's hip and thighs from the chair seat. Thus, the present invention prevents the user feeling hot and stuffy since the user's body heat is not diffused directly to a foam material stuffed within the chair seat. Furthermore, the user's body heat is dissipated by the hollow area defined by the first cushion body, the second cushion body and the at least one third cushion body and by the plural gaps at the connection regions of the three cushion bodies to improve comfortability.
5. The foldable seat cushion of the present invention also comprises soft pads on the first cushion body, the second cushion body and the third cushion body which improve comfortability of the user.
6. The foldable seat cushion of the present invention can be placed directly on a floor, a tatami and a lawn when a chair in not available, and the user can sit on the present invention as sitting on a chair.
