Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, and in particular to a vehicle seat. The utility model also relates to a vehicle equipped with the vehicle seat. Background Art

[0002] The comfort and versatility of vehicle seats are increasingly becoming a key concern for consumers. Traditional vehicle seat designs typically consist of a backrest, a seat cushion, and a headrest fixed to the upper portion of the backrest. These components primarily provide basic seating support and head protection for passengers. However, with the increase in long-distance driving and diverse travel demands, passengers are placing higher demands on seat flexibility and adaptability.

[0003] In order to meet the needs of rest and loading, most existing vehicle seats have a lie-flat function, that is, the angle of the backrest is adjusted so that the backrest and the rear seat cushion are roughly flush, allowing the driver and passenger to lie flat on the seat to meet the need for rest. Since there is a headrest on the top of the backrest, in order to prevent the headrest from interfering with the rear seat cushion when the backrest is laid flat, the headrest needs to be removed from the backrest. However, if the removed headrest is placed arbitrarily in the vehicle cabin, it will not only affect the cleanliness and aesthetics of the vehicle interior. At the same time, when normal driving and riding are required, the driver and passenger may easily forget to install the headrest back on the top of the backrest, resulting in the driver and passenger's head not being supported by the headrest. This makes the driver and passenger's head and neck vulnerable to injury when the vehicle brakes suddenly or encounters a collision, which in turn leads to a decrease in safety. Utility Model Content

[0004] In view of this, the present invention aims to provide a vehicle seat that improves riding comfort while preventing the headrest from being randomly placed, thereby improving the cleanliness and safety of the vehicle interior.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A first headrest mounting structure is provided at the top of the backrest, and a second headrest mounting structure is provided at the front end of the seat cushion;

[0008] When the vehicle seat is in a sitting position, the headrest can be set at the top of the backrest through the first headrest mounting structure to be in a headrest state. When the vehicle seat is in a lying position, the headrest can be set at the front end of the seat cushion through the second headrest mounting structure to be in a leg support state.

[0009] Furthermore, a headrest rod is provided on the headrest; the first headrest mounting structure and the second headrest mounting structure both include a headrest guide sleeve for inserting the headrest rod, and a locking assembly for locking the headrest rod.

[0010] Furthermore, there are two headrest rods arranged side by side; the headrest guide sleeves in the first headrest mounting structure and the second headrest mounting structure are both arranged in a one-to-one correspondence with the headrest rods, and the locking assembly is provided at at least one of the headrest guide sleeves.

[0011] Furthermore, the top of the backrest and the front end of the seat cushion are respectively provided with fixing tubes; the headrest guide sleeve in the first headrest mounting structure and the headrest guide sleeve in the second headrest mounting structure are both arranged in the fixing tubes at corresponding positions.

[0012] Furthermore, the fixing tube on the backrest is connected to the backrest frame in the backrest and is located at the upper end of the upper crossbeam bent tube in the backrest frame; and / or, the fixing tube on the seat cushion is connected to the bottom of the seat basin assembly in the seat cushion through a connecting bracket.

[0013] Furthermore, the first headrest mounting structure and / or the second headrest mounting structure is provided with a detection mechanism for sensing the headrest.

[0014] Furthermore, the detection mechanism includes a sensor arranged at the fixing tube; when the headrest rod of the headrest is inserted into the headrest guide sleeve, the sensor can be triggered and output a sensing signal.

[0015] Furthermore, a window is provided on the headrest guide sleeve, and an opening is provided on the fixing tube that is aligned with the window; when the headrest rod of the headrest is inserted into the headrest guide sleeve, the sensor senses the headrest through the opening and the window.

[0016] Furthermore, a connecting plate is provided on the fixing tube, and the sensor is clamped on the connecting plate.

[0018] The vehicle seat of the present invention, by providing a headrest, as well as a first headrest mounting structure and a second headrest mounting structure, allows the headrest to function as a leg rest, thereby improving riding comfort. Furthermore, the second headrest mounting structure prevents the headrest from being placed haphazardly. This prevents passengers from forgetting to attach the headrest to the backrest, thus preventing injuries to the head and neck due to lack of headrest support. This improves the cleanliness and safety of the vehicle interior.

[0019] Furthermore, the coordinated arrangement of the headrest guide sleeve and the locking assembly allows the headrest rod to be inserted into the guide sleeve and locked by the locking assembly, thereby securing the headrest. The two headrest rods are arranged side by side, improving the stability of the headrest. Furthermore, in both the first and second headrest mounting structures, only one headrest guide sleeve can be provided with the locking assembly, ensuring effective rod securement while reducing costs.

[0020] In addition, mounting tubes are provided at the top of the backrest and the front end of the seat cushion. These serve as the mounting base for the headrest guide sleeves, facilitating their attachment to the backrest and seat cushion via the mounting tubes, enhancing their securement. The backrest mounting tubes are connected to the backrest frame within the backrest, while the seat cushion mounting tubes are connected to the bottom of the seat pan assembly within the seat cushion via a connecting bracket, ensuring a stable connection between the mounting tubes and both the backrest and seat cushion.

[0021] Furthermore, a detection mechanism for sensing the headrest is provided at the first headrest mounting structure or the second headrest mounting structure, which can detect whether a headrest is installed at the first headrest mounting structure or the second headrest mounting structure, and limit the function of adjusting the backrest angle to avoid damage to the headrest due to adjusting the backrest angle.

[0022] The detection mechanism includes a sensor mounted on the mounting tube.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] Example 1

[0048] This embodiment relates to a vehicle seat, which has an overall structure and is combined with Figure 1 As shown, it includes a seat cushion 1 , a backrest 2 and a headrest 3 .

[0049] The backrest 2 is adjustable relative to the seat cushion 1, and a first headrest mounting structure A is provided at the top of the backrest 2, and a second headrest mounting structure B is provided at the front end of the seat cushion 1. Figure 1 and combined Figure 2 As shown, when the vehicle seat is in a sitting position, the headrest 3 can be installed on the top of the backrest 2 through the first headrest mounting structure A to be in the headrest 3 state. When the vehicle seat is in a lying position, the headrest 3 can be installed at the front end of the seat cushion 1 through the second headrest mounting structure B to be in the leg support state.

[0050] It is understood that when the vehicle seat is in the seating position and the driver and passenger are seated on the seat, the driver and passenger's head can rest against the headrest 3. When the vehicle seat is converted to the lying-flat position, the angle of the backrest 2 needs to be adjusted to make it flat, and the headrest 3 needs to be removed to prevent the headrest 3 from interfering with the rear seat cushion 1. After the backrest 2 is flat, the headrest 3 is installed at the front end of the seat cushion 1 to facilitate the driver and passenger to rest in the vehicle compartment.

[0051] As described above, by providing the headrest 3, as well as the first headrest mounting structure A and the second headrest mounting structure B, the headrest 3 can be used as a leg rest, thereby improving riding comfort. Furthermore, since the headrest 3 must be removed when the backrest 2 is laid flat, the provision of the second headrest mounting structure B prevents the headrest 3 from being arbitrarily placed. Furthermore, when the vehicle seat is converted from a lying position to a sitting position, the driver and passenger must reinstall the headrest 3 on the backrest 2 before being able to ride normally. This prevents the driver and passenger from forgetting to install the headrest 3 on the backrest 2, thereby preventing injury to the driver and passenger's head and neck due to lack of support from the headrest 3, thereby improving the cleanliness and safety of the vehicle interior.

[0052] Based on the above overview, specifically, this embodiment features an adjustment button 8 on one side of the seat cushion 1 for adjusting the angle of the backrest 2. Operating adjustment button 8 activates a corresponding drive motor within the seat to adjust the angle of the backrest 2. Furthermore, by combining the headrest 3 with a leg rest, the leg rest function is achieved without requiring an additional leg rest structure, thus reducing production costs.

[0053] As a specific implementation form, Figure 3 、 Figure 4 As shown, the headrest 3 of this embodiment is provided with a headrest rod 301. Both the first headrest mounting structure A and the second headrest mounting structure B include a headrest guide sleeve 4 for receiving the headrest rod 301 and a locking assembly 5 for locking the headrest rod 301. The cooperation between the headrest guide sleeve 4 and the locking assembly 5 allows the headrest rod 301 on the headrest 3 to be inserted into the guide sleeve 4 and locked by the locking assembly 5, thereby securing the headrest 3 and ensuring its stability between the backrest 2 and the front end of the seat cushion 1.

[0054] Specifically, there are two headrest rods 301 arranged side by side. The headrest guide sleeves 4 in the first headrest mounting structure A and the second headrest mounting structure B are both arranged in a one-to-one correspondence with the headrest rods 301, and a locking assembly 5 is provided on at least one of the headrest guide sleeves 4. The provision of two headrest rods 301 and two headrest guide sleeves 4 ensures that the headrest 3 will not rotate when mounted and fixed on the seat cushion 1 or the backrest 2, thereby further ensuring the support effect of the headrest 3 on the head or legs. At the same time, in the first headrest mounting structure A and the second headrest mounting structure B, only one headrest guide sleeve 4 may be provided with a locking assembly 5, thereby reducing the cost of the first headrest mounting structure A and the second headrest mounting structure B while ensuring the fixing effect on the headrest rod 301, or both headrest guide sleeves 4 may be provided with a locking assembly 5 to further improve the fixing effect on the headrest rod 301.

[0055] In specific implementation, Figure 5As shown in the figure, the locking component 5 of this embodiment includes a locking piece slidably disposed at the end of the headrest guide sleeve 4. A hole for the headrest rod 301 to pass through is provided on the locking piece, and an elastic member is provided between the locking piece and the end of the headrest guide sleeve 4. When the headrest rod 301 is inserted into the headrest guide sleeve 4, the elastic member can push against the locking piece to move, so that the locking piece is caught in the limiting groove on the headrest rod 301. In addition, the locking component 5 of this embodiment can also adopt other conventional locking structures for locking the headrest rod 301 on vehicle seats in the prior art.

[0056] In this embodiment, in order to facilitate the installation and fixation of the headrest guide sleeve 4, as Figure 1 , Figure 2 and Figure 3 shown, fixing tubes 6 are respectively provided at the top of the backrest 2 and the front end of the seat cushion 1. The headrest guide sleeve 4 in the first headrest mounting structure A and the headrest guide sleeve 4 in the second headrest mounting structure B are both arranged in the fixing tubes 6 at the corresponding positions. It can be understood that since the headrest guide sleeve 4 is mostly made of plastic material, the headrest guide sleeve 4 cannot be directly connected to the frame structures inside the backrest 2 and the seat cushion 1. By providing the fixing tube 6 as the installation base for the headrest guide sleeve 4, it is convenient to install and fix the headrest guide sleeve 4 on the backrest 2 and the seat cushion 1 through the fixing tube 6, and improve the fixing effect of the headrest guide sleeve 4.

[0057] Specifically, as Figure 3 shown, the fixing tube 6 on the backrest 2 of this embodiment is connected to the backrest 2 frame in the backrest 2 and is located at the upper end of the upper cross beam elbow 201 in the backrest 2 frame. In addition, as Figure 4 shown, the fixing tube 6 on the seat cushion 1 of this embodiment is connected to the bottom of the seat pan assembly 101 in the seat cushion 1 through the connecting bracket 102. Thus, by installing the fixing tube 6 on the backrest 2 frame and the seat pan assembly 101, the connection stability between the fixing tube 6 and the backrest 2 and the seat cushion 1 is ensured, thereby improving the installation and fixation stability of the headrest guide sleeve 4 on the backrest 2 and the seat cushion 1, and ensuring that the headrest 3 can effectively support the head or legs of the driver and passengers. In specific implementation, each fixing tube 6 is made of metal material and is welded to the upper cross beam elbow 201 and the connecting bracket 102 to ensure the connection strength between the fixing tube 6 and the backrest ² frame and the seat pan assembly 101.

[0058] In specific implementation, the connecting bracket 102 of this embodiment has a "C" - shaped structure, and the opening of the connecting bracket 102 faces the rear of the vehicle seat. Setting the connecting bracket 102 as a "C" - shaped structure makes the connecting bracket 102 have a certain elasticity, so that the headrest 3 in the leg rest state can form an elastic support for the legs of the driver and passengers, thereby improving the comfort of the legs of the driver and passengers.

[0059] When adjusting the angle of the backrest 2 to flatten it, the headrest 3 in its engaged position interferes with the rear seat cushion 1. As a result, passengers may forget to remove the headrest 3 when adjusting the angle of the backrest 2, causing the headrest 3 to be squeezed by the rear seat cushion 1, leading to damage to the headrest 3 and the first headrest mounting structure A. Therefore, in this embodiment, a detection mechanism for sensing the headrest 3 is provided at one or both of the first headrest mounting structure A and the second headrest mounting structure B. This detection mechanism can detect whether the headrest 3 is installed at the first headrest mounting structure A or the second headrest mounting structure B, limiting the angle adjustment function of the backrest 2. This prevents damage to the headrest 3 caused by adjusting the angle of the backrest 2 and prevents passengers from forgetting to install the headrest 3 on the backrest 2, further ensuring driving safety.

[0060] For example, the detection mechanism detects whether a headrest 3 is installed in the first headrest 3 installation mechanism. When the headrest 3 is installed, it can restrict the backrest 2 from being laid flat, which would otherwise damage the headrest 3. When the headrest 3 is not installed, it can restrict the backrest 2 from being erected, preventing the vehicle seat from returning to a sitting position. This prevents the headrest 3 from not being installed on the backrest 2, and prevents the driver and passenger's head from being injured due to lack of support from the headrest 3. In addition, the detection mechanism detects whether a headrest 3 is installed in the second headrest 3 installation mechanism. When the headrest 3 is not installed, it can restrict the backrest 2 from being laid flat, preventing the headrest 3 from being randomly placed in the vehicle. When the headrest 3 is installed, it restricts the backrest 2 from being erected, preventing the headrest 3 in the leg-rest position from affecting the driver and passenger's riding.

[0061] Among them, such as Figure 5 As shown, the detection mechanism of this embodiment includes a sensor 7 disposed on the fixing tube 6. When the headrest rod 301 of the headrest 3 is inserted into the headrest guide sleeve 4, the sensor 7 is triggered and outputs a sensing signal. Therefore, by detecting whether the headrest rod 301 is inserted into the headrest guide sleeve 4, it can be determined whether the headrest 3 is installed in the first headrest 3 mounting mechanism or the second headrest 3 mounting mechanism.

[0062] Specifically, as a specific implementation form, the headrest guide sleeve 4 of this embodiment is provided with a window 401, and the fixing tube 6 is provided with an opening 601 aligned with the window 401. When the headrest rod 301 of the headrest 3 is inserted into the headrest guide sleeve 4, the sensor 7 senses the headrest 3 through the opening 601 and the window 401. The provision of the opening 601 and the window 401 allows the sensing end of the sensor 7 to be as close as possible to the headrest rod 301, thereby ensuring that the sensor 7 accurately detects whether the headrest rod 301 is inserted. In a specific implementation, the sensor 7 of this embodiment can be a Hall sensor 7, an optical sensor 7, or a contact sensor 7, etc., capable of detecting whether the headrest rod 301 is inserted into the headrest guide sleeve 4. Furthermore, the sensor 7 of this embodiment can also adopt other types of sensors 7 and other installation arrangements and sensing methods to determine whether the headrest 3 is installed.

[0063] On this basis, to facilitate the fixing of sensor 7, a connecting plate 602 is provided on the fixing tube 6 of this embodiment. Sensor 7 is snapped onto connecting plate 602. A snap is provided on one side of sensor 7, and connecting plate 602 is provided with a slot for snapping with the snap. The snap connection between connecting plate 602 and sensor 7 facilitates installation and removal of sensor 7, thereby facilitating assembly and maintenance of sensor 7. In a specific implementation, connecting plate 602 is formed by bending the wall of fixing tube 6 outward. Due to the bending of connecting plate 602, the aforementioned opening 601 is formed on fixing tube 6 at a position corresponding to connecting plate 602.

[0064] In summary, the vehicle seat of this embodiment, by providing a headrest 3, as well as a first headrest mounting structure A and a second headrest mounting structure B, enables the headrest 3 to be used as a leg rest, thereby improving riding comfort. Furthermore, since the headrest 3 must be removed when the backrest 2 is laid flat, the provision of the second headrest mounting structure B prevents the headrest 3 from being arbitrarily placed. Furthermore, when the vehicle seat is converted from a lying position to a sitting position, the driver and passenger must reinstall the headrest 3 on the backrest 2 before being able to ride normally. This prevents the driver and passenger from forgetting to install the headrest 3 on the backrest 2, thereby preventing injury to the driver and passenger's head and neck due to lack of support from the headrest 3. This improves the cleanliness and safety of the vehicle interior and provides excellent practicality.

[0066] This embodiment relates to a vehicle, in which the vehicle seat described in the first embodiment is provided.

[0067] The vehicle seat arrangement of this embodiment allows the headrest 3 to function as a leg rest, improving passenger comfort and facilitating rest within the vehicle. Furthermore, the provision of the first mounting mechanism and the second headrest mounting structure B prevents the headrest 3 from being randomly placed within the vehicle, preventing passengers from forgetting to reattach the headrest 3 to the backrest 2, thereby improving vehicle interior cleanliness and safety.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
