[0038] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0039] A ventilated headrest assembly includes a headrest body, wherein a ventilation mechanism 4 is provided inside the headrest body; the present invention enables the headrest to have a ventilation function by installing a ventilation mechanism 4 inside the headrest, which facilitates airflow and cooling of the head of passengers and improves the comfort of the head area of ​​passengers in the vehicle.

[0040] The ventilated headrest assembly disclosed in this invention mainly includes a headrest body, which is the main structure of the headrest assembly. In this invention, a ventilation mechanism 4 is provided inside the headrest body. The ventilation mechanism 4 is mainly used for supplying air to facilitate the blowing of air onto the head of the person sitting in the headrest body area.

[0041] In this invention, the headrest body includes a headrest body; the headrest body is the main structure of the headrest body, which facilitates the head support of passengers during subsequent use. In this invention, the headrest body is provided with a ventilation channel 11; the ventilation channel 11 mainly serves as a connection, facilitating the air blown out by the ventilation mechanism 4 to pass through the headrest body and blow air onto the head of the passenger.

[0042] Meanwhile, in this invention, the ventilation mechanism 4 is connected to the headrest body; the ventilation mechanism 4 can supply air into the ventilation channel 11; the ventilation mechanism 4 has many types, and the ventilation mechanism 4 is detachably connected to the headrest body. The ventilation mechanism 4 can be a motor plus a fan, or it can be a conventional ventilation pump structure. After the mechanism is started, it can blow out gas, which is convenient for blowing air into the headrest body area.

[0043] Furthermore, the headrest body described in this invention includes a headrest frame 3 and a foam matrix connected to the headrest frame 3; the headrest frame 3 provides excellent support and ensures the overall structural strength of the headrest body, while the foam matrix is ​​made of soft material, which can provide soft support for the head of the passenger and ensure the passenger's comfort.

[0044] In this invention, the ventilation mechanism 4 is arranged on the headrest frame 3. This arrangement facilitates the installation and arrangement of the ventilation mechanism 4 on the headrest body.

[0045] Meanwhile, in this invention, the foamed substrate and the ventilation mechanism 4 are arranged on opposite sides of the headrest frame 3; the headrest frame 3 is provided with ventilation holes 31; the foamed substrate has a ventilation channel 11, and the ventilation holes 31 are connected to the ventilation channel 11; the gas provided by the ventilation mechanism 4 passes through the ventilation holes 31 and enters the ventilation channel 11 of the foamed substrate, and the gas can be discharged through the channel, thereby allowing the gas to pass through the headrest body and blow onto the head of the passenger.

[0046] Furthermore, the foamed substrate in this invention includes a headrest substrate 2 and a headrest foam 1. Both the headrest substrate 2 and the headrest foam 1 can be made of foamed material. The headrest substrate 2 has an overall arc-shaped block structure, while the headrest foam 1 has a rectangular block structure. This design facilitates contact with the head of the passenger, ensures the contact area between the foamed substrate and the passenger's head, and ensures the comfort of the passenger's head.

[0047] Furthermore, in this invention, the ventilation channel 11 is disposed on the headrest foam 1, which is connected to the headrest frame 3 via the headrest base 2. The headrest base 2 is provided with a through hole 21, which is connected to the ventilation hole 31. Based on the above design, this invention facilitates the connection of the headrest foam 1, the headrest base 2, and the headrest frame 3. In actual connection, the headrest base 2 is fixed to the headrest frame 3, and the connection methods are diverse and can be selected as needed, such as adhesive bonding. In addition, in this invention, the through hole 21 and the ventilation hole 31 are arranged opposite to each other, which facilitates the entry of the gas supplied by the subsequent ventilation mechanism 4 into the ventilation channel 11 on the headrest foam 1, thereby facilitating the subsequent air venting operation.

[0048] Furthermore, in this invention, the headrest foam 1 is embedded in the headrest base 2; the headrest base 2 is provided with an embedding groove 22, and the headrest foam 1 is arranged in the embedding groove 22; the embedding groove 22 provided on the headrest base 2 of this invention serves as a storage function, facilitating the placement and arrangement of the headrest foam 1 on the headrest base 2. In addition, in this invention, the embedding groove 22 is located in the central region of the headrest base 2; this allows the inner sidewall of the embedding groove 22 to define the circumferential position of the headrest foam 1, and in this invention, the headrest foam 1 can be bonded to the headrest base 2 with adhesive; based on this arrangement, the stability of the headrest foam 1 arranged in the headrest base 2 is ensured.

[0049] Furthermore, in this invention, the ventilation channel 11 includes a duct groove 101 and a through hole group 102 disposed on the headrest foam body 1; the duct groove 101 and the through hole group 102 are interconnected; the through hole group 102 is arranged on the side of the headrest foam body 1 away from the headrest base 2, that is, on the side closer to the passenger during subsequent use, while the duct groove 101 is close to the headrest base 2. During subsequent use, the ventilation mechanism 4 supplies gas into the duct groove 101, and the gas then flows from the duct groove 101 to the through hole group 102, and then is exhausted through the through hole group 102 to blow on the passenger's head; thereby achieving ventilation and cooling of the passenger's head.

[0050] In this invention, the depth of the air duct groove 101 is less than the thickness of the headrest foam 1. This arrangement makes the air duct groove 101 equivalent to being located on one side of the headrest foam 1, which can ensure the flatness of the headrest foam 1 on the side close to the passenger as much as possible, and ensure the comfort of the passenger.

[0051] In addition, the through-hole group 102 described in this invention includes a plurality of individual through holes 113. Each individual through hole 113 extends from the air duct groove 101 away from the air duct groove 101 on the headrest foam body 1. The plurality of individual through holes 113 ensures the ventilation of the headrest foam body 1. By using the air duct groove 101 in conjunction with the plurality of individual through holes 113, this invention can ensure that the air blown out by the ventilation mechanism 4 can pass through and reach the head area of ​​the passenger, thereby improving the comfort of the passenger.

[0052] Furthermore, the air duct trough 101 described in this invention includes multiple parallel and spaced individual troughs 111, each individual trough 111 being a part of the air duct trough 101. The individual troughs 111 are inclined, and adjacent two or more individual troughs 111 are connected by at least one connecting trough 112. This arrangement allows the headrest foam 1 to form a grid-like structure near the foam matrix, facilitating subsequent gas flow. In addition, the connecting trough 112 serves as a connection, allowing gas supplied by the ventilation mechanism 4 to diffuse through one or more individual troughs 111 after entering them, ensuring gas distribution in each individual trough 111 as much as possible. This arrangement increases the headrest's air outlet area, which is beneficial for cooling multiple areas of the passenger's head and achieving cooling of more areas of the passenger's head.

[0053] In this invention, the individual sink 111 is set at a 45-degree angle to the horizontal plane, and the connecting sink 112 is arranged intersecting with the individual sink 111. Generally, it is required that the connecting sink 112 and the individual sink 111 are set perpendicular to each other. This arrangement can achieve the connection between the individual sinks 111 with the shortest distance. At the same time, at the intersection of the connecting sink and the individual sink 111, a rounded surface is required for transition. This arrangement can reduce the running resistance of gas in the air duct sink 101 and help ensure the diffusion range of gas in the headrest body.

[0054] Furthermore, in this invention, the headrest foam 1 is provided with a wind-blocking layer 6 on the side near the headrest base 2. The wind-blocking layer 6 serves as a covering and blocking layer, primarily covering the air duct groove 101 during subsequent use to prevent air leakage on the side of the air duct groove 101 near the headrest base 2. In this invention, the wind-blocking layer 6 can be made of non-woven fabric. The wind-blocking layer 6 is attached to the headrest foam 1, and the two can be connected by adhesive bonding or other methods. In this invention, the wind-blocking layer 6 covers the air duct groove 101, making the air duct groove 101 equivalent to an internal trough structure, facilitating the regional limitation of gas entering the headrest foam 1 and ensuring the air output of the headrest.

[0055] In addition, the wind-blocking layer 6 in this invention is provided with ventilation holes 61; the ventilation holes 61, the connecting holes 21 and the ventilation holes 31 are connected in sequence; this arrangement facilitates the entry of the gas supplied by the ventilation mechanism 4 into the headrest foam body 1.

[0056] Furthermore, in this invention, the headrest frame 3 is a plastic frame; the plastic frame can reduce the overall weight of the headrest while ensuring the main body of the headrest.

[0057] In this invention, the headrest body also includes a headrest back cover 5; the headrest back cover 5 is hollow to form a placement cavity; the headrest back cover 5 serves as a shield and protection, and at the same time, it can form an internal cavity to facilitate the placement of the headrest body; in this invention, the headrest back cover 5 is connected to the headrest frame 3; the two can be connected by bolts or by snap-fit.

[0058] Furthermore, the ventilation mechanism 4 in this invention includes a ventilation pump, which can supply air to the headrest body. The ventilation pump includes a pump housing, which facilitates the installation of the ventilation pump on the headrest frame 3.

[0059] In addition, the ventilation pump described in this invention is connected to the headrest frame 3 via a fastening component. The fastening component facilitates the connection between the ventilation pump and the headrest frame 3. Specifically, the fastening component in this invention includes a support column provided on the headrest frame 3. The pump housing overlaps the support column. Subsequently, the pump housing is connected to the support column by bolts passing through it. This arrangement facilitates the installation and use of the ventilation pump on the headrest frame 3.

[0060] Furthermore, the ventilated headrest assembly described in this invention includes two ventilation mechanisms 4, which are spaced apart on the headrest frame 3. The ventilation pumps in the two ventilation mechanisms 4 are connected through the same wiring harness assembly 41. This arrangement reduces the use of the wiring harness assembly 41 while ensuring air supply. The two ventilation mechanisms 4 disclosed in this invention are symmetrically arranged on the headrest frame 3, and the wiring harness assembly 41 is arranged on the headrest frame 3 through wiring harness clips. The headrest frame 3 of this invention has an overall arc-shaped structure, so the two ventilation mechanisms 4 are arranged at the upper end of the headrest frame 3, and the air outlet directions of the two ventilation mechanisms 4 are intersecting. This arrangement can better ensure the diffusion of gas in the air duct groove 101.

[0061] A seat assembly including the ventilated headrest assembly. Specific implementation examples:

[0063] The ventilated headrest assembly disclosed in this invention mainly comprises a headrest foam body 1, a headrest base 2, a headrest frame 3, a ventilation mechanism 4, and a headrest back cover 5; the headrest foam body 1, headrest base 2, headrest frame 3, ventilation mechanism 4, and headrest back cover 5 are connected in sequence.

[0064] The ventilated headrest assembly disclosed in this invention can provide a ventilation system and a comfortable textured foam structure in addition to normal adjustment without affecting the normal function of the headrest, thereby increasing the comfort of the headrest area.

[0065] The headrest is similar in size to a regular headrest, and the ventilation mechanism 4 enhances the comfort and user experience of the seat.

[0066] In this invention, the headrest foam body 1 and the headrest base 2 are mainly made of foamed materials, and the headrest frame 3 is mainly supported by plastic. Generally, high-strength plastic materials are selected, which have the characteristics of being lightweight and high-strength. The headrest frame 3 is required to effectively support the headrest and its accessories to ensure structural stability.

[0067] In this invention, the headrest foam 1 and the headrest base 2 are made of foam material; the texture on the headrest foam 1 can take various shapes, such as wave shape, grid shape, honeycomb shape, etc., and the ventilation channel 11 can be arranged through the ingenious design of these textures, and different textures can be adopted according to different shapes.

[0068] The mesh-like pattern disclosed in this invention is mainly formed by ventilation channels 11, which is formed by the intersecting arrangement of multiple individual sinks 111 and connected sinks 112. The mesh-like pattern forms multiple small channels, increasing the air circulation speed and further improving the heat dissipation effect; while the textured foam helps to reduce the pressure points between the head and the headrest, increasing the amount of head intrusion of the occupant and improving comfort.

[0069] The mesh pattern possesses the following characteristics;

[0070] 1. Excellent ventilation: The grid pattern, with its multiple small channels arranged in an interlaced manner, forms an effective airflow path; hot air can be quickly exhausted through these small channels, achieving efficient heat dissipation.

[0071] 2. Uniform pressure distribution: The mesh structure can evenly distribute pressure on the head, reduce single-point pressure, and improve riding comfort; uniform pressure distribution can also reduce fatigue caused by long-term riding.

[0072] 3. High structural strength: The interlaced grid pattern has high strength and stability, which can provide sufficient support while ensuring ventilation and enhancing the overall durability of the headrest.

[0073] Adaptable to various head shapes: The grid pattern can adaptively adjust to different head shapes, providing a better fit and support, further enhancing passenger comfort.

[0074] Compared with other texture shapes:

[0075] Wavy texture: While wavy textures offer advantages in ventilation and comfort, they are inferior to grid textures in terms of uniform pressure distribution and structural strength. Furthermore, the manufacturing process for wavy textures is relatively complex, increasing costs.

[0076] Honeycomb pattern: Honeycomb patterns excel in strength and lightweight design, but their complex structure may increase manufacturing difficulty and cost. Additionally, honeycomb patterns are slightly inferior to grid patterns in terms of uniform pressure distribution.

[0077] Considering all the above factors, choosing a grid pattern as the preferred option not only significantly improves ventilation and riding comfort, but also ensures the structural strength of the headrest and the controllability of manufacturing costs, making it an ideal choice.

[0078] In addition, because the ventilation channel 11 is relatively wide, this invention also requires that a wind-blocking layer 6 be pasted on the headrest foam 1. The wind-blocking layer 6 is mainly non-woven fabric. In use, the non-woven fabric is pasted on the headrest foam 1 to seal the ventilation channel 11 to prevent air leakage. When installing the headrest foam 1, the two reserved 40mm ventilation holes 61 are aligned with the ventilation holes 31 on the headrest frame 3. Specifically, the non-woven fabric is required to have two 40mm diameter circular ventilation holes 61 at the ventilation mechanism 4 position.

[0079] Ventilation mechanism 4: Built-in small suction mechanism; the mechanism is fastened to the headrest plastic with screws, and features low noise and high efficiency; ventilation mechanism 4 is connected to the seat power supply through a wiring harness, and the user can control the ventilation effect through a switch.

[0080] During installation, the headrest frame 3 is first assembled with the ventilation mechanism 4 and the wiring harness to form the first small assembly. The non-woven fabric and the headrest foam 1 are then connected and glued onto the headrest base 2 to form the second small assembly. The first small assembly, the second small assembly, the cover, and the headrest back cover 5 are then assembled into the headrest assembly. The headrest is then installed on the seat and the wiring harness is connected. The occupant can start the ventilation mechanism 4 by turning on the switch to use the headrest.

[0081] Obviously, the specific implementation of this invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
