Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a flexible pressure-sensing pad for automotive seats and an automotive seat. Background Technology

[0002] The car seat is equipped with a flexible pressure-sensing pad that can detect the pressure distribution of passengers on the car seat in real time, so that the car seat can make corresponding comfort adjustments (such as surface adjustment). It can adjust the seat surface according to the passenger's body contour to ensure a better fit between the car seat and the passenger's body, thereby reducing the fatigue of passengers sitting for long periods of time, and can evenly distribute the pressure brought by the passenger's body weight, reducing concentrated pressure on specific parts of the passenger.

[0003] Existing flexible pressure-sensing pads for car seats are typically rectangular, laid flat across the seat back and cushion. However, in actual use, most detection points on these pads are invalid, as passengers don't actually press on them. This design fails to consider human anatomy, resulting in numerous invalid detection points and excessively high costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a flexible pressure sensing pad for car seats and a car seat with low cost, which is designed with pressure detection points according to human body structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a flexible pressure-sensing pad for a car seat, wherein the car seat includes a backrest, and the flexible pressure-sensing pad includes:

[0006] The backrest is arranged in a shoulder sensing area, a back sensing area, and a waist sensing area from top to bottom. Rib sensing areas are arranged on both sides of the waist sensing area. The shoulder sensing area, back sensing area, and waist sensing area are all located close to the middle of the backrest. Detection blind spot areas are formed on both sides of the shoulder sensing area and the back sensing area.

[0007] Several pressure sensing elements are provided in the shoulder sensing area, back sensing area, waist sensing area, and rib sensing area.

[0008] Furthermore, the flexible pressure sensing pad includes a flexible pad sheet body, and the shoulder sensing area, back sensing area, waist sensing area and rib sensing area are all located on the flexible pad sheet body;

[0009] The flexible pad body has cutouts on both sides of the shoulder sensing area and the back sensing area, and the cutouts are detection blind spot areas.

[0010] Furthermore, the pressure sensing elements are arranged in a matrix in the shoulder sensing area, back sensing area, waist sensing area, and rib sensing area.

[0011] Furthermore, two rows of pressure sensing elements are arranged at intervals in the shoulder sensing area, back sensing area, and waist sensing area.

[0012] Furthermore, a row of pressure sensing elements is arranged in the rib sensing area on one side of the waist sensing area, and a row of pressure sensing elements is also arranged in the rib sensing area on the other side of the waist sensing area.

[0013] Furthermore, multiple fixing points are arranged on the flexible pad sheet body, and the flexible pressure sensing pad is fixed to the backrest through the multiple fixing points.

[0014] Furthermore, fixed points are arranged near the shoulder sensing area, back sensing area, waist sensing area and rib sensing area, and the fixed points are set as suspension points.

[0015] Furthermore, through grooves are provided between the shoulder sensing area and the back sensing area, and between the waist sensing area and the rib sensing area, and the through grooves are set as suspension points.

[0016] Furthermore, the main body of the flexible pad is non-woven fabric, and the pressure sensing element is a pressure sensing sheet.

[0017] This utility model also proposes a car seat, characterized in that it includes a backrest, the outer surface of which is covered with a cover, and the inner surface of the cover is provided with the aforementioned flexible pressure-sensitive pad.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In this invention, the flexible pressure sensing pad includes a shoulder sensing area, a back sensing area, and a waist sensing area arranged sequentially from top to bottom, as well as rib sensing areas arranged on both sides of the waist sensing area. Detection blind spot areas are formed on both sides of the shoulder sensing area and the back sensing area. Detection points are only set at important detection positions, that is, the detection points are arranged according to the human body structure to accurately identify the pressure distribution. This eliminates many invalid detection points on existing flexible pressure sensing pads and can effectively reduce the cost of flexible pressure sensing pads.

[0020] In this invention, the flexible pressure-sensing pad includes a flexible pad sheet body, which is made of non-woven fabric, making it easy to place on the back of a car seat cover without affecting the basic comfort function of the car seat. Hollowed-out areas are provided on both sides of the flexible pad sheet body near the shoulder sensing area and the back sensing area. These hollowed-out areas are blind spot areas, which can reduce the material cost of the flexible pressure-sensing pad.

[0021] In this invention, fixed points, i.e., suspension points, are arranged near the shoulder sensing area, back sensing area, waist sensing area, and rib sensing area. The flexible pressure sensing pad is fixed in the car seat through these suspension points, which can ensure reliable fixation and does not affect the ventilation and heating functions of the car seat.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] like Figure 1 As shown in this embodiment, a flexible pressure-sensing pad for a car seat is provided. The car seat includes a backrest and generally also includes a seat cushion, with the backrest rotatably mounted on the seat cushion. The flexible pressure-sensing pad of this embodiment includes, from top to bottom, a shoulder sensing area 110, a back sensing area 120, and a lumbar sensing area 130. Rib sensing areas 140 are respectively provided on both sides of the lumbar sensing area 130. The shoulder sensing area 110, back sensing area 120, and lumbar sensing area 130 are all located near the center of the backrest. When a passenger sits in the car seat with their back against the backrest, the central area of ​​the backrest is generally the effective detection area. Therefore, in this embodiment, the shoulder sensing area 110, the back sensing area 120, and the waist sensing area 130 are all located near the center of the backrest. The detection areas are arranged according to the structure of the human body and the actual usage scenario. The shoulder sensing area 110 can detect the shoulder pressure of the passenger, the back sensing area 120 can detect the back pressure of the passenger, and the waist sensing area 130 can detect the waist pressure of the passenger. Detection blind spots are formed on both sides of the shoulder sensing area 110 and the back sensing area 120. These detection blind spots cannot detect the pressure exerted by the passenger on the car seat, as these areas are mostly invalid detection areas. Therefore, setting these areas as detection blind spots can effectively reduce material costs.

[0032] A plurality of pressure sensing elements 200 are provided in the shoulder sensing area 110, back sensing area 120, waist sensing area 130 and rib sensing area 140. Preferably, the pressure sensing element 200 in this embodiment is a pressure sensing sheet, which is an electronic component that can sense and respond to changes in external pressure and belongs to a type of pressure sensor.

[0033] In practical use, the flexible pressure sensing pad of this embodiment includes a shoulder sensing area 110, a back sensing area 120, and a waist sensing area 130 arranged sequentially from top to bottom, as well as rib sensing areas 140 arranged on both sides of the waist sensing area 130. Detection blind spot areas are formed on both sides of the shoulder sensing area 110 and the back sensing area 120. Detection points are only set at important detection positions, that is, the detection points are arranged according to the human body structure to accurately identify the pressure distribution. This eliminates many invalid detection points on the existing flexible pressure sensing pads, which can effectively reduce the cost of the flexible pressure sensing pad.

[0034] Specifically, the flexible pressure-sensing pad in this embodiment includes a flexible pad body 100. The shoulder sensing area 110, back sensing area 120, waist sensing area 130, and rib sensing area 140 are all located on the flexible pad body 100. The flexible pad body 100 in this embodiment is made of non-woven fabric. It should be explained that non-woven fabric is a sheet-like material made by bonding oriented or randomly arranged fibers together through friction, cohesion, or adhesion. It does not require specific weaving. Non-woven fabric is lightweight, soft, and comfortable to the touch; it has a loose structure and good breathability and moisture resistance. It has advantages such as no warp or weft threads, easy cutting and sewing, short production process, high output, relatively low price, low cost, and recyclability. In this embodiment, the flexible pad body is made of non-woven fabric, which facilitates the placement of the flexible pressure-sensing pad on the inside of the backrest cover without affecting the comfort function of the car seat.

[0035] In this embodiment, the flexible pad body 100 has cutout positions 150 on both sides of the shoulder sensing area 110 and the back sensing area 120. The cutout positions 150 are detection blind spots. These cutout positions 150 do not require non-woven fabric or pressure sensing elements 200, which can effectively reduce material costs.

[0036] In this embodiment, the pressure sensing elements 200 are arranged in a matrix in the shoulder sensing area 110, back sensing area 120, waist sensing area 130, and rib sensing area 140. Instead of a large-area coverage pressure sensing element 200, the matrix-distributed pressure sensing elements 200 are used to precisely sense only key points, thereby reducing manufacturing costs.

[0037] Furthermore, two rows of pressure sensing elements 200 are arranged at intervals in the shoulder sensing area 110, back sensing area 120, and waist sensing area 130, which matches the structure of the human shoulder, back, and waist, ensuring that the key detection locations are covered with pressure sensing elements 200. Additionally, a row of pressure sensing elements 200 is arranged in the rib sensing area 140 on one side of the waist sensing area 130, and another row of pressure sensing elements 200 is arranged in the rib sensing area 140 on the other side of the waist sensing area 130. When the flexible pressure sensing pad is placed in the back of a car seat, the rib sensing areas 140 on both sides of the waist sensing area 130 are located at the side wings.

[0038] In practical use, the flexible pressure-sensing pad of this embodiment includes a flexible pad body 100, which is made of non-woven fabric, making it easy to place on the back of a car seat cover without affecting the basic comfort function of the car seat. Hollowed-out positions 150 are provided on both sides of the flexible pad body 100 near the shoulder sensing area 110 and the back sensing area 120. These hollowed-out positions 150 are blind spot areas, which can reduce the material cost of the flexible pressure-sensing pad.

[0039] When a flexible pressure-sensing pad is placed in the backrest of a car seat, the issue of fixing the pad needs to be addressed. Therefore, in this embodiment, multiple fixing points 10 are arranged on the main body 100 of the flexible pad. These fixing points 10 secure the flexible pressure-sensing pad to the backrest, ensuring reliable fixation. Specifically, fixing points 10 are arranged near the shoulder sensing area 110, back sensing area 120, waist sensing area 130, and rib sensing area 140. These fixing points 10 are used as suspension points to fix the various parts of the flexible pressure-sensing pad, preventing displacement during use. Further specifically, through grooves are provided between the shoulder sensing area 110 and the back sensing area 120, and between the waist sensing area 130 and the rib sensing area 140. These through grooves are used as suspension points. The use of these suspension points ensures stable installation of the flexible pressure-sensing pad, and allows the car seat to accommodate suspension, heating, and ventilation functions.

[0040] When the flexible pressure-sensing pad of this embodiment is placed on the back of a car seat, a cover is wrapped around the outer surface of the backrest, and the flexible pressure-sensing pad of this embodiment is disposed on the inner surface of the cover.

[0041] When the flexible pressure-sensing pad of this embodiment is installed in the back of a car seat, it can adjust its shape according to the curves of the human body, evenly distributing body pressure, reducing localized pressure, and avoiding soreness and discomfort caused by prolonged sitting. The flexible pressure-sensing pad can fill the gap between the car seat and the human body, providing effective support for the shoulders, back, waist, and ribs, maintaining the natural curve of the spine, and reducing muscle fatigue.

[0042] In this solution, the pressure detection points on the flexible pressure sensing pad are designed according to the structure of the human body, and some invalid pressure detection points are eliminated, which can effectively reduce the manufacturing and configuration costs of the flexible pressure sensing pad.
