[0003] In terms of head and neck comfort, soft pillows are generally installed to support the human body. However, during the use of the same vehicle, different passengers or the same passenger may have different needs for soft pillows under different circumstances. In this case, if it is necessary to lower the height of the soft pillow or remove the soft pillow, the soft pillow needs to be removed, which is time-consuming and laborious. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a car seat soft headrest and a car seat.

[0005] This invention provides a car seat soft headrest, disposed on a car seat, comprising: An elastic support body, wherein the elastic support body is made of a porous elastic material, and the elastic support body is used to provide support for the human body; A soft pillowcase covers the elastic support body and is made of a non-breathable material.

A controller is used to control the operating status of the gas source.

[0006] According to the technical solution provided in the embodiments of the present invention, the air source also has an inflation function, used to inflate the soft pillow cover.

[0007] According to the technical solution provided by the embodiments of the present invention, a first air pressure sensor is also included, which is used to detect the air pressure inside the soft pillow cover.

[0008] According to the technical solution provided in the embodiments of the present invention, the material of the elastic support is at least one of memory foam, natural latex, bio-fleece, and PP cotton.

[0009] According to the technical solution provided in the embodiments of the present invention, a noise-absorbing and anti-clogging component is provided at the connection position between the vent and the vent pipe.

[0010] According to the technical solution provided in the embodiments of the present invention, a constraint layer is provided between the elastic support body and the soft pillow cover, and the constraint layer is breathable.

[0011] According to the technical solution provided in the embodiments of the present invention, a covering layer is provided between the elastic support body and the soft pillow cover, the covering layer completely covers the elastic support body, and a connecting hole is provided thereon, the connecting hole is connected to the air pipe, the air pipe is connected to the air source, and the air source is also used to extract the gas in the covering layer.

[0012] According to the technical solution provided in the embodiments of the present invention, a second pressure sensor is further included, which is used to detect the pressure inside the coating layer.

[0013] According to the technical solution provided in the embodiments of the present invention, the soft headrest cover is provided with a connector for connecting to the car seat.

[0014] According to the technical solution provided by the embodiments of the present invention, the soft pillow surface is fitted onto the side of the headrest body protective cover of the car seat that is close to the human body, and is fixedly connected to the headrest body protective cover.

[0015] On the other hand, a car seat is provided, including a car seat cushion and a receiving space disposed on the car seat back or headrest, the receiving space being used to store the car seat cushion.

[0018] This invention uses an air source with a suction function to extract gas from the non-breathable material of the soft headrest cover. Because the elastic support is a porous elastic structure, it is compressed as the gas is extracted, thus reducing the height of the car seat headrest and allowing for shape adjustment. When the gas is extracted to its maximum value, the car seat headrest is flattened, eliminating the need for passengers to use it. The flattened headrest can be stored back into the car seat through a storage space on the seat back or headrest. This solution satisfies passengers' adjustment needs for the car seat headrest, avoids the complex operation of repeated disassembly and reassembly, and also meets the aesthetic requirements of the car seat.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. Similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0023] Please refer to Figure 1 , Figure 2 , Figures 10-12 As shown, the present invention provides a car seat soft pillow, disposed on a car seat, comprising: Elastic support 1, which is made of porous elastic material, is used to provide support for the human body. Soft pillowcase 2, which covers the elastic support body 1, is made of non-breathable material, and has ventilation holes 3 on it, which are connected to ventilation pipes 4. Air source 5 is connected to ventilation pipe 4 and has at least an air extraction function to extract the gas inside the soft pillow cover 2. Controller 6 is used to control the working status of gas source 5.

[0024] Specifically, such as Figure 1As shown, the elastic support 1 is made of a porous elastic material that can hold gas. When a person compresses the soft headrest of the car seat, the elastic support 1 deforms to conform to the curves of the body, improving comfort. The headrest cover 2 is made of a non-breathable material, which can be a dense material, such as high-density synthetic fiber, or a coated material, such as a waterproof membrane (e.g., TPU, PTFE) or coating on a fabric base to block gas flow. The elastic support 1 is located inside the headrest cover 2, which has ventilation holes 3 connected to the ventilation pipe 4. Simultaneously, the air source 5, connected to the ventilation pipe 4, is connected to the ventilation holes 3. Figure 2 As shown, the air source 5 has at least a suction function, which can extract the gas from the soft pillowcase 2 and the elastic support 1, thereby reducing the air pressure inside the soft pillowcase 2 and the elastic support 1, compressing the soft pillow of the car seat, and lowering its height. The controller 6 is used at least to turn the suction function of the air source 5 on or off, controlling the working state of the air source 5.

[0025] Furthermore, the air source 5 also has an inflation function, used to inflate the soft pillow cover 2.

[0026] Specifically, such as Figure 3 , Figure 4 As shown, the air source 5 can also be used to inflate the soft headrest cover 2, either passively or actively. The air source 5 may include a valve body connected to the environment. When the valve body is open, the vent 3 connects to the environment, and the air pressure inside the soft headrest cover 2 balances with the ambient air pressure, restoring the car seat soft headrest to its natural height; this is called passive inflation. The air source 5 may also include a compression component, which increases the gas pressure to inflate the soft headrest cover 2; this is called active inflation. Inflating the soft headrest cover 2 with the air source 5 can change the height and / or firmness of the car seat soft headrest, making the adjustment options for the car seat soft headrest more versatile.

[0027] Furthermore, it also includes a first air pressure sensor 7, which is used to detect the air pressure inside the soft pillowcase 2.

[0028] Specifically, Figure 9 As shown, the first air pressure sensor 7 is electrically connected to the controller 6 and is used to detect the air pressure inside the soft headrest cover 2. On the one hand, it can serve as a protective measure. When the air pressure inside the soft headrest cover 2 exceeds the set threshold, air can be released through the air source 5 to reduce the air pressure inside the soft headrest cover 2 and prevent damage to the soft headrest cover 2. On the other hand, the controller 6 can be associated with the vehicle body control module and automatically adjust the air pressure inside the soft headrest cover 2 to the set value according to the instructions of the vehicle body control module.

[0029] Furthermore, the elastic support 1 is made of at least one of memory foam, natural latex, bio-fleece, and PP cotton.

[0030] Specifically, a single material can be used as the elastic support 1, or multiple composite materials can be used to make the elastic support 1.

[0031] Furthermore, a noise-reducing and anti-blocking component 8 is provided at the connection point between the vent 3 and the vent pipe 4.

[0032] Specifically, such as Figure 1 As shown, the noise reduction and anti-clogging component 8 has a porous structure, which prevents the elastic support 1 itself or the generated debris from clogging the vent 3. At the same time, it can reduce the noise generated when the airflow enters and exits the accommodating space and improve the NVH performance of the car seat.

[0033] Furthermore, a constraint layer 9 is provided between the elastic support 1 and the soft pillow cover 2, and the constraint layer 9 is breathable.

[0034] Specifically, such as Figure 5 As shown, the constraint layer 9 can be non-woven fabric. The constraint layer 9 covers the outside of the elastic support 1 to prevent the elastic support 1 itself or the generated debris from clogging the vent 3, thus preventing the air pressure regulation function inside the containment space from failing and improving the reliability of the product.

[0035] Furthermore, a covering layer 10 is provided between the elastic support 1 and the soft pillow cover 2. The covering layer 10 completely covers the elastic support 1 and has a connecting hole 11. The connecting hole 11 is connected to the air pipe 12, and the air pipe 12 is connected to the air source 5. The air source 5 is also used to extract the gas inside the covering layer 10.

[0036] Specifically, such as Figure 6 As shown, the covering layer 10 is made of a non-breathable material. When the air source 5 performs the air extraction function, the gas in the soft pillow cover 2 and the gas in the covering layer 10 are extracted simultaneously, thereby adjusting the height of the car seat soft pillow.

[0037] Furthermore, it also includes a second pressure sensor 13, which is used to detect the air pressure inside the covering layer 10.

[0038] Specifically, such as Figure 9 As shown, the second air pressure sensor 13 is electrically connected to the controller 6 and is used to detect the air pressure inside the covering layer 10. On the one hand, it can serve as a protective measure. When the air pressure inside the covering layer 10 exceeds the set threshold, air can be released through the air source 5 to reduce the air pressure inside the covering layer 10 and prevent damage to the covering layer 10. On the other hand, the controller 6 can be associated with the vehicle body control module and automatically adjust the air pressure inside the covering layer 10 to the set value according to the instructions of the vehicle body control module.

[0039] Furthermore, the soft headrest cover 2 is provided with a connector 14 for connecting to the car seat.

[0040] Specifically, Figure 10 , Figure 11 As shown, the soft headrest cover 2 can be installed and fixed to the car seat through a separately provided connector 14. The connector 14 can be a strap, elastic band, hook, etc. It can be tightened on the headrest body or headrest rod of the car seat through the elastic band, or it can be hooked to the headrest rod or other structures of the car seat for easy installation and fixation.

[0041] Furthermore, the soft pillowcase 2 is located on the side of the headrest body protective cover 15 of the car seat that is close to the human body and is fixedly connected to the headrest body protective cover 15.

[0042] Specifically, such as Figure 12 As shown, the soft headrest cover 2 can be sewn or welded to the headrest body protective cover 15 of the car seat to avoid loose installation and improve the stability of installation.

[0043] On the other hand, the present invention provides a car seat, including a car seat soft pillow, and also includes a receiving space disposed on the car seat back or headrest, the receiving space being used to store the car seat soft pillow.

[0044] Specifically, the foam of the car seat back or headrest can be provided with receiving grooves, which form receiving spaces. The receiving grooves can be cuts made in the foam, which can deform to form spaces due to the elasticity of the foam, or they can be grooves cut out to form a cavity with space inside. The cover of the car seat back or headrest is also provided with corresponding receiving openings. When the car seat soft pillow is in a flattened state, it can be stored in the receiving groove through the receiving opening, realizing the storage of the car seat soft pillow and avoiding the complicated operation of disassembly and assembly.

[0045] Furthermore, it also includes storage components installed on car seats.

[0046] Specifically, the storage components are located within the receiving space and can be elastic straps or mechanically driven telescopic mechanisms, such as linkages or rack and pinion drives.

[0047] One end of the storage component is fixed to the side of the accommodating space away from the seat surface, and the other end is connected to the car seat cushion. When the car seat cushion contains gas, it is held in place outside the accommodating opening due to its own volume, providing support for the occupant. When the car seat cushion is deflated to a flat state, the car seat cushion is pulled into the accommodating space through the accommodating opening due to the pulling force applied by the storage component, thus achieving automatic storage.

[0048] The above description is merely a preferred embodiment of the present invention and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention is not limited to the specific combination of the above-described technical features, but also includes other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this invention.
