Description

Seat back thoracic sacral support

This creation is related to a chair back device, especially a thoracic sacral support

The backs of office chairs, gaming chairs, and waiting chairs are all one-piece backs. At first glance, they can provide support for the human body’s torso. However, in reality, each person’s torso height, leg length, and sitting posture are different. Improper sitting posture leads to the failure of the chair back to provide ideal trunk support and body feedback, resulting in skeletal muscle pain in the trunk when sitting.

Therefore, in order to solve the appeal problem, the purpose of this creation is to provide a chair back device that can respond to different torso heights, different leg lengths, improve sitting posture, provide support for the thoracic spine, and remind the sitting person to avoid hunchback postures. The support of the sacrum stabilizes the pelvis and reminds the sitting person to avoid forward movement of the pelvis.

The technical means used in this creation to solve the problems of conventional technology is to provide a chair back support device, including: back frame, seat fixing frame, thoracic support rod, sacral support rod, chair surface, thoracic support, Sacral support. The upper and lower two-piece seat back design provides strong support for the protrusions on the back of the torso. The back frame and support rods can be moved on the back frame to accommodate different heights and protrusions on the back of the torso. For users with different heights, use the seat fixing frame and support The strut can be moved back and forth to cope with users with different leg lengths and different degrees of hunchback. The thoracic spine support and the sacral spine support that can be tilted back and forth are used to cope with users with different spine curvatures. Use an adjustable tilt chair surface to prevent users from moving excessively toward the front edge of the chair.

Fig. 1 is a schematic side view showing a thoracic sacral support for a chair back according to an embodiment of the present invention.

Fig. 2 is a front schematic diagram showing the thoracic sacral support device of the chair back according to an embodiment of the invention.

The following describes the implementation of this creation based on Figure 1 and Figure 2. This description is not intended to limit the implementation of this creation, but is a kind of creation embodiment.

As shown in Figure 1, the thoracic sacral vertebra support device 100 implemented in the first creation of the present invention is a two-stage upper and lower back support, including: back frame 1, seat fixing frame 2, thoracic spine support rod 3, sacral spine Support rod 4, chair surface 5, thoracic support 1a, sacral support 2a.

As shown in Fig. 1, the thoracic sacral vertebra support device 100 implemented in the first creation of the present invention is a chair back supported by two upper and lower sections. The thoracic sacral vertebra support device 100 has two upper and lower supports, and the thoracic spine support 1a Compared with the sacral support 2a, the support can provide good support for the thoracic and sacral spine of the torso when in a sitting posture, and avoid hunchback posture.

As shown in Figure 1, the thoracic sacral spine supporter 100 implemented in the first creation of the present invention is a chair back that supports up and down in two sections. The thoracic sacral spine support 100 has a back frame 1 that can move up and down. Moving the back frame 1 when sitting can provide users with different heights and different heights of the protrusions behind the torso can have a good chest Vertebral support effect.

As shown in Figure 1, the thoracic sacral vertebrae supporter 100 implemented in the first creation of the present invention is a chair back that supports up and down in two sections. The thoracic sacral spine supporter 100 has a thoracic spine that can move up and down on the back frame 1. The support rod 3 and the sacral vertebra support rod 4, moving the support rods 3 and 4 in a sitting posture can provide users with different heights and different heights of the back of the torso to have a good thoracic and sacral support effect.

As shown in Fig. 1, the thoracic sacral spine supporter 100 implemented in the first creation of the present invention is a chair back that supports up and down in two stages. The thoracic sacral spine support 100 has a seat fixing frame 2 that can move forward and backward. , The seat holder 2 can move forward and backward when sitting in a sitting posture to adjust the depth of the chair surface to adapt to users with different leg lengths to prevent people with short legs from being unable to lean the pelvis against the sacral support 2a or the back edge of the lower leg to the chair The front edge of face 5 produces a poor sitting posture.

As shown in Fig. 1, the thoracic sacral spine support 100 implemented in the present invention is a two-stage support back and the thoracic sacral support 100 has a thoracic spine support rod 3 that can move forward and backward. The thoracic spine support rods 3 that can be stretched back and forth in a sitting posture can produce a good thoracic spine support effect for users with different degrees of hunchback.

As shown in Figure 1, the thoracic sacral spine supporter 100 implemented in the present invention is a two-stage support back, and the thoracic sacral spine support 100 has a sacral support rod 4 that can move forward and backward. , The sacral support rod 4 that can move back and forth when sitting in a sitting posture can prevent users with different leg lengths from being unable to lean the pelvis against the sacral support 2a or the back edge of the calf to the front edge of the chair surface 5. Sitting position.

As shown in Figure 1, the thoracic sacral spine support 100 implemented in the present invention is a two-stage support back and the back thoracic sacral support 100 has a thoracic spine support 1a and The sacral spine support 2a, the thoracic spine support 1a and the sacral spine support 2a that can be tilted back and forth when in a sitting posture, can respond to different spine curvatures so that the user can produce good thoracic and sacral support.

As shown in Fig. 1, the thoracic sacral vertebra support device 100 implemented in the present invention is a two-stage support back and forth. The thoracic sacral vertebra support device 100 has a seat surface 5 that can adjust the tilt angle. The seat surface 5, which can adjust the inclination angle when in a sitting posture, can prevent the buttocks from excessively sliding toward the front edge of the seat surface 5.

As shown in Fig. 1, the thoracic-sacral vertebral support device 100 implemented in the present invention is a two-stage support for a chair back, a back frame that can move the chair back up and down 1, and a seat fixing frame 2 that can move back and forth. , The thoracic spine support rod 3 and the sacral spine support rod 4 that can be moved forward and backward, the thoracic spine support 1a and the sacral support 2a that can be tilted back and forth, and the chair surface 5 that can adjust the tilt angle are examples. The user adopts a sitting posture and adjusts the height of the back frame 1 according to his own height so that the height of the thoracic spine support rod 3 is the same as the most protruding part of the back thoracic spine; and the seat holder 2 and the sacral support rod are adjusted according to their leg length 4 Adjust to your desired chair surface 5 depth; and adjust the thoracic support rod 3 and the sacral support rod 4 according to the curvature of your torso spine to support the force of the spine; and adjust the thoracic support 1a, The sacral support 2a is adjusted to fit and support the torso; and the inclination angle of the chair surface 5 is adjusted according to the pressure state of the hips and the back of the thighs to achieve a state where the chin is retracted, the head is not nodded, the shoulders are not shrugged, and the pelvis is neutral.
