Description

Technical Field

[0001] This invention relates to the field of lumbar support technology, specifically a chest wrap-style lumbar support sling that connects to a car seat. Background Technology

[0002] A lumbar support is a piece of fabric used to protect the waist, also called a lumbar pad. With the development of science and technology, the materials used for lumbar supports are no longer limited to ordinary fabrics, and their function is no longer limited to keeping warm.

[0003] As people's living standards improve, they are paying more and more attention to health and safety. Some people need to sit in a car for long periods of time for various reasons. Without any assistance, the user's upper body weight will be entirely on their lower back. Maintaining this relatively fixed posture for a long time can easily lead to the lower back muscles being in a state of tension for a long time, which may cause symptoms such as lumbar muscle strain. Furthermore, it will increase the burden on the lumbar spine and intervertebral discs, excessively stretching the muscles and ligaments of the lower back, and ultimately leading to lumbar disc herniation. Secondly, if the user's waist cannot be supported to strengthen the lumbar support points, it will also increase the user's fatigue.

[0004] Therefore, there is an urgent need for a chest-wrap lumbar support strap that connects to car seats to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a chest wrap-style lumbar support sling that connects to a car seat, which has the advantage of protecting the waist and solves the problems mentioned in the background art.

The back surface of the chest wrap second is fixedly connected with several buttons that match the buckle straps first.

[0009] The fastening structure includes two binding straps (first) fixedly connected to the waist support belt. Each binding strap (first) has a housing on its surface. The housing works in conjunction with two breast wraps (first and second). Two symmetrically arranged sliding grooves are formed at the bottom of the inner cavity of the housing. A spring is fixedly connected to one side of each groove, and a slider is fixedly connected to one end of each spring, forming a sliding connection between the groove and the slider. A toothed plate is fixedly connected to the top of each slider. Two symmetrically arranged rotating rods are rotatably connected to the inner cavity of the housing. Gears are fixedly connected to the surface of each rotating rod, meshing with the toothed plate. A positioning rod adapted to the binding strap (first) is fixedly connected to one side of the gear surface, and a connecting plate is fixedly connected to one side of the toothed plate.

[0010] The connecting assembly includes a second binding strap that is fixedly connected to the binding strap one on the right side. The second binding strap has several positioning holes on one side, and a buckle is engaged in the inner cavity of the positioning hole. One side of the buckle is fixedly connected to the binding strap one on the left side.

[0011] Furthermore, as a preferred embodiment of the present invention, the top of both the first and second breast wraps are fixedly connected to a plurality of second buckle straps, the surface of each second buckle strap is fitted with a hook, and a cotton pad is fixedly connected to one side of each hook.

[0012] Furthermore, as a preferred embodiment of the present invention, the front surface of the waist support belt is provided with a second type of hook and loop fastener, the front side of the waist support belt is provided with two symmetrically arranged pads, and the back surface of the pads is provided with a second type of hook and loop fastener that is compatible with the second type of hook and loop fastener.

[0013] Furthermore, as a preferred embodiment of the present invention, both the first and second breast wraps have adjustment holes on their front surfaces, and an adjustment block is slidably connected to the inner cavity of the adjustment hole, with one side of the adjustment block being fixedly connected to the shell.

[0014] Furthermore, as a preferred embodiment of the present invention, the inner ring of the spring is provided with a round rod, both ends of which are fixedly connected to the sliding groove, and the slider is located on the surface of the round rod and is slidably connected to the round rod.

[0015] Furthermore, as a preferred embodiment of the present invention, one side of the linkage plate extends to the outside of the housing and is fixedly connected to a push plate.

[0016] Furthermore, as a preferred embodiment of the present invention, a positioning strap is fixedly connected to the back surface of the second chest wrap, and the positioning strap is used in conjunction with the connecting strap.

[0017] Furthermore, as a preferred embodiment of the present invention, the waist support belt is provided with extension portions at both the top and bottom, and the through holes are located on the extension portions.

[0018] A method for using a chest-wrapping lumbar support sling that connects to a car seat, the method comprising the following steps:

[0019] Step 1: Place the second restraint strap on the top of the car seat surface, then pull the second restraint strap so that the buckle engages with the appropriate positioning hole and is fastened, thereby positioning the second restraint strap and adding support points for the lumbar support belt.

[0020] Step Two: Place the lumbar support belt behind the user, using the through holes for ventilation and heat dissipation. The lumbar support should be in close contact with the user's back. Next, wrap the second chest wrap around the user's chest, and then wrap the first chest wrap around the user's chest from the other side. At this time, the second chest wrap will cause the first female Velcro to attach to the first female Velcro, thus positioning the second chest wrap. Then, attach the first chest wrap to the second chest wrap and use the connecting strap to pass through the inner cavity of the positioning strap. Finally, use the buckle to select the appropriate button to fasten it. This process positions the first chest wrap and achieves the purpose of supporting the user's waist.

[0021] Step 3: Move the first restraint strap from the back to the front of the user. Then, press the push plate with both hands. The push plate moves the connecting plate, which in turn moves the gear plate. As the gear plate moves, it causes the slider to slide in the inner cavity of the groove. This process limits and guides the gear plate. Then, as the gear plate moves, it drives the gear to rotate. When the gear rotates, it drives the two positioning rods to rotate in opposite directions. Further, pass the first restraint strap through the inner cavity of the shell until the second restraint strap is adjusted to the appropriate position. At this point, the first restraint strap passes through the user's shoulder. Finally, release the pressure on the push plate. The elastic potential energy of the spring will drive the gear plate, gear, positioning rods, connecting plate, and push plate back to their original positions. This positions the first restraint strap, strengthening the support point of the lumbar support belt and preventing the user's upper body weight from being entirely on the waist.

[0022] Beneficial effects: The technical solution of this application has the following advantages: This invention has the advantage of protecting the waist. In actual use, the chest wrap structure is wrapped around the user's chest. At this time, the lumbar support increases the sturdiness of the back of the chest wrap structure. The position of the chest wrap strap 1 and chest wrap strap 2 on the user's chest is adjusted by using the first and second Velcro straps. Then, the chest wrap strap 1 is positioned by using the combination of the buckle and the button, which also helps to improve the stability of the chest wrap structure. Secondly, the binding strap 1 passes over the user's shoulder. By adjusting the position of the binding strap 1 through the structure, the binding strap 1 contacts the user's shoulder and helps to position the chest wrap structure, thus providing a support point for the chest wrap structure and preventing the user's upper body from pressing entirely on the user's waist, which helps to protect the user's waist. Finally, by using the setting of the connecting component, the chest wrap structure and the fastening structure can be connected to the car seat, which further increases the support point and helps to relieve the user's fatigue.

[0023] It should be understood that all combinations of the foregoing concepts and the additional concepts described in more detail below can be considered part of the inventive subject matter of this disclosure, provided that such concepts do not contradict each other. Attached Figure Description

[0052] Step 1: Place the second restraint strap 21 on the top of the car seat surface, then pull the second restraint strap 21 so that the buckle 23 selects the appropriate positioning hole 22 and engages and fastens, thereby positioning the second restraint strap 21 and adding support points for the lumbar support belt 1.

[0053] Step 2: Place the lumbar support belt 1 behind the user, using the through hole 3 for ventilation and heat dissipation. The lumbar support 2 is in close contact with the user's back. Next, wrap the chest wrap 2 5 around the user's chest, and then wrap the chest wrap 1 4 around the user's chest from the other side. At this time, the chest wrap 2 5 will cause the female Velcro 7 to fit with the female Velcro 6 on the chest wrap 1 4, thereby positioning the chest wrap 2 5. Then, attach the chest wrap 1 4 to the chest wrap 2 5, and use the connecting strap 8 to pass through the inner cavity of the positioning strap 34. Then, use the buckle strap 1 9 to select the appropriate button 10 to fasten it. This process positions the chest wrap 1 4 and achieves the purpose of supporting the user's waist.

[0054] Step 3: Move the restraint strap 11 from the back to the front of the user. Then, press the push plate 33 with both hands. The push plate 33 moves the connecting plate 20, which in turn moves the toothed plate 15. As the toothed plate 15 moves, it causes the slider 14 to slide within the inner cavity of the groove 13. This process serves to limit and guide the toothed plate 15. Next, the movement of the toothed plate 15 causes the gear 17 to rotate. The rotation of the gear 17 causes the two positioning rods 18 to rotate in opposite directions. Further, the restraint strap... The first strap 11 passes through the inner cavity of the housing 12 until the second strap 21 is adjusted to the appropriate position. At this time, the first strap 11 passes through the user's shoulder. Finally, the pressure on the push plate 33 is released, and the elastic potential energy of the spring 19 drives the toothed plate 15, gear 17, positioning rod 18, linkage plate 20 and push plate 33 back to their original positions. This achieves the function of positioning the first strap 11, thereby strengthening the support point of the waist support belt 1 and preventing the user's upper body weight from being entirely pressed on the waist.

[0055] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
