Description

Technical Field

[0001] The invention belongs to the technical field of seat structures, and more specifically, relates to a car seat and a car. Background Art

[0002] Cars are not only a means of transportation, but also provide a good resting place for short-term parking and rest. Car seats should not only ensure the safety and comfort of drivers and passengers during driving, but also meet the needs of parking and resting.

[0003] When driving, the car seat can provide support and protection for the human body. The seat shape matches the normal sitting posture and can fit the human body surface well, allowing the driver and passengers to feel even pressure, soft and comfortable. However, when the seat back is folded down for rest (that is, when the driver and passengers are in a lying position), the existing curved surface of the upper part of the seat back and the headrest will be away from the back of the human body, which will not provide enough support for the back and head, causing the back to lean back too much, resulting in poor comfort for the driver and passengers after the seat is folded down, and it is difficult to meet the use needs in the lying state. Summary of the invention

[0004] The object of the present invention is to provide a car seat and a car, which can reliably support the lower part of the human body of the driver and the passenger when the driver and the passenger are resting, thereby improving the comfort of the driver and the passenger in a lying state.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a car seat, including a seat cushion, a seat back and a shoulder air bag embedded in the seat back, wherein the shoulder air bag has an open state after inflation and a folded state after deflation, and the shoulder air bag can be laid flat on the upper part of the seat back in the open state to support the head, neck and lower back of the driver and passenger, and can be embedded in the seat back in the folded state.

[0006] In a possible implementation, a first air pump connected to the shoulder air bag and used to inflate the shoulder air bag or release the gas in the shoulder air bag is provided on the seat back, and a first air valve is provided on the first air pump.

[0007] In a possible implementation, the car seat further includes a controller disposed on the seat cushion, wherein the controller is electrically connected to the first air valve and is configured to send an inflation command or a deflation command to the first air valve.

[0010] In one possible implementation, the seat cushion is provided with a second air pump that is connected to the hip air bag and is used to inflate the hip air bag or release the gas in the hip air bag. The second air pump is provided with a second air valve that is electrically connected to the controller, and the controller is used to send inflation instructions or deflation instructions to the second air valve.

[0011] In some embodiments, the seat cushion and the seat back are rotatably connected to form a mounting gap for accommodating a hip airbag between the seat cushion and the seat back. The hip airbag is disposed in the mounting gap and extends laterally along the rear side wall of the seat cushion.

[0012] In some embodiments, when the shoulder airbags and the hip airbags are respectively inflated, the thickness of the shoulder airbags gradually increases from bottom to top, and the thickness of the hip airbags gradually increases from front to back.

[0013] In a possible implementation, the seat back includes a backrest body and a headrest disposed above the backrest body, and an embedding hole for accommodating a shoulder airbag is provided between the headrest and the backrest body.

[0014] Compared with the prior art, the solution shown in the embodiment of the present application provides a car seat in which, after the driver and passenger lay down the seat back to rest, the shoulder air bag embedded in the seat back can be inflated to an open state and laid under the driver and passenger's head, shoulders and back, thereby effectively supporting the corresponding parts of the driver and passenger, meeting the support requirements for the human body in a lying position, improving the comfort of the driver and passenger when lying flat, and meeting the driver and passenger's daily needs for lying rest.

[0015] The present invention also provides a car, comprising a car seat. The car can meet the needs of the driver and passengers for lying down and resting by adjusting the seat profile, while meeting the safety of the driver and passengers' sitting posture, thereby improving the technological sense of the car and the comfort of the driver and passengers.

[0026] Please also read Figures 1 to 5The automobile seat and automobile provided by the present invention are now described. The automobile seat comprises a seat cushion 1, a seat back 2, and a shoulder airbag 3 embedded in the seat back 2, wherein the shoulder airbag 3 has an open state after inflation and a folded state after deflation. The shoulder airbag 3 can be laid flat on the upper part of the seat back 2 in the open state to support the head, neck and lower back of the driver and passenger 6, and can be embedded in the seat back 2 in the folded state.

[0027] Compared with the prior art, the car seat provided in the present embodiment has a shoulder air bag 3 embedded in the seat back 2 that can be inflated to an open state after the driver and passenger 6 lays down the seat back 2 to rest, and is laid under the head, shoulders and back of the driver and passenger 6, thereby effectively supporting the corresponding parts of the driver and passenger 6, meeting the support requirements for the human body in a lying state, improving the comfort of the driver and passenger 6 when lying flat, and meeting the driver and passenger 6's daily needs for rest in a lying position.

[0028] During actual use, when the driver and passenger 6 is in a sitting position, the shoulder airbag 3 is in a folded state and can be embedded in the seat back 2 to ensure the comfort of the driver and passenger 6 in the sitting position.

[0029] When the car stops running, the seat back 2 is adjusted to swing downward so that the driver and passenger 6 is in a lying position. The shoulder airbag 3 is inflated so that the shoulder airbag 3 expands and stretches on the upper part of the seat back 2, forming an effective support for the head, neck and back of the human body, so that the corresponding parts of the human body are reliably supported, thereby improving the comfort of the driver and passenger 6 in a lying position and improving the comfort during rest.

[0030] When the driver and passenger 6 needs to change from a lying position to a sitting position, the seat back 2 is adjusted to swing upward, and then the gas in the shoulder air bag 3 is discharged to the outside, and the shoulder air bag 3 with the gas discharged can be embedded on the seat back 2, which is simple, convenient and fast to operate. The above structure enables the car seat to meet the use requirements of different scenarios such as riding and parking and resting, improves the comfort of the driver and passenger 6, and provides a good driving experience for the driving heat source.

[0031] The above structure can ensure the safety of the driver and passenger 6 in a sitting state when driving and the comfort of the driver and passenger 6 in a lying state when parking. It not only meets the normal use requirements of the car seat during normal driving of the car, but also meets the comfort requirements of the seat when parking and resting, so that the user's rest experience is better, and at the same time it also improves the technological sense of the car.

[0032] In some possible implementations, the above-mentioned characteristic seat back 2 is adopted as follows Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The seat back 2 is provided with a first air pump 21 which is in communication with the shoulder air bag 3 and is used to inflate the shoulder air bag 3 or release the gas in the shoulder air bag 3 , and the first air pump 21 is provided with a first air valve 22 .

[0033] In this embodiment, a first air pump 21 capable of inflating the shoulder air bag 3 is provided, and the inflation and deflation of the shoulder air bag 3 is realized by opening the first air valve 22. The first air pump 21 is connected to the shoulder air bag 3 through a connecting pipe, and the first air pump 21 can be arranged in the seat back 2 to ensure the stability of the position of the connecting pipe and avoid the position displacement of the connecting pipe and the first air pump 21 caused by the opening or closing of the shoulder air bag 3.

[0034] It should be noted that the first air pump 21 is an integrated pump for inflation and degassing, which can perform two operations, namely, degassing or inflating the shoulder air bag 3, and is controlled by the first air valve 22 to meet the switching requirements of the shoulder air bag 3 between the opening and the closing. The above structure simplifies the inflation and deflation process of the shoulder air bag 3, improves the convenience of switching the car seat between the sitting and lying states of the driver and passenger 6, ensures the comfort of the driver and passenger 6 in different states, and meets the use requirements in different states.

[0035] Specifically, the first air valve 22 is used to control the opening and closing and the filling and deflation state of the first air pump 21. The first air valve 22 is preferably arranged on the side of the seat back 2, which is not only convenient for manual control, but also convenient for subsequent maintenance operations.

[0036] For some possible implementations, see Figure 1 , Figure 3 and Figure 5 The car seat also includes a controller 5 arranged on the seat cushion 1 , and the controller 5 is electrically connected to the first air valve 22 and is used to send an inflation command or a deflation command to the first air valve 22 .

[0037] In this embodiment, in order to realize the automatic opening and closing of the shoulder air bag 3, a controller 5 electrically connected to the first air valve 22 is also provided. The controller 5 can control the first air valve 22 according to a preset program, thereby realizing the operation of inflating or deflating the shoulder air bag 3.

[0038] Furthermore, the inflation time can be preset, and the controller 5 can control the opening time of the first air valve 22, so that the shoulder airbag 3 can reach the required amount of inflation during the inflation process. On this basis, a central control screen electrically connected to the controller 5 can be used to input the inflation amount on the central control screen to realize the controller 5's control over the first air valve 22.

[0039] On this basis, the controller 5 can also be made to automatically memorize the last inflation amount through a preset program, and the shoulder airbag 3 will be inflated to the last inflation amount the next time it is needed, and then manual input adjustment can be performed.

[0040] As a parallel embodiment, a pressure sensor (piezoelectric pressure sensor) can also be set in the shoulder air bag 3 to feedback the internal pressure parameters thereof, and transmit the pressure parameters to the controller 5. The controller 5 determines the difference between the actual pressure value and the preset pressure value according to a preset program, and then determines whether to send an inflation control instruction to the first air valve 22, until the actual pressure value fed back by the pressure sensor is consistent with the preset pressure value, and the inflation operation is completed.

[0041] In some embodiments, the above-mentioned characteristic seat cushion 1 can be used as follows Figure 1 , Figure 3 and Figure 5 See the structure shown. Figure 1 , Figure 3 and Figure 5 An angle sensor 12 electrically connected to the controller 5 is also provided on the side of the seat cushion 1 . The angle sensor 12 is used to monitor the pitch angle of the seat back 2 to generate angle parameters and send the angle parameters to the controller 5 .

[0042] In this embodiment, an angle sensor 12 is provided to detect the angle parameters of the seat back 2, and the angle parameters are then fed back to the controller 5 through the angle sensor 12, so that the controller 5 can determine whether to inflate the shoulder airbag 3 according to a preset program, thereby eliminating the tedious manual operation and realizing automatic adjustment.

[0043] Specifically, the seat back 2 is connected to the seat cushion 1 through a rotating shaft. When the seat swings downward around the rotating shaft to an angle greater than 60 degrees with the vertical plane, the controller 5 receives the angle parameter transmitted by the angle sensor 12, and can judge according to the preset program that it is necessary to switch to the lying state at this time and the shoulder air bag 3 needs to be inflated. At this time, the controller 5 sends an inflation control instruction to the first air valve 22, and the first air pump 21 inflates the shoulder air bag 3 to achieve automatic control, which is convenient for the driver and passenger 6 to use.

[0044] When the angle between the seat back 2 and the vertical plane is less than 50°, the controller 5 receives the angle parameter transmitted by the angle sensor 12, and can judge according to the preset program that it is necessary to switch to the sitting state at this time and the shoulder air bag 3 needs to be deflated. At this time, the controller 5 sends a deflation control instruction to the first air valve 22, and the first air pump 21 deflates the shoulder air bag 3, so that the driver 6 can fold and store the shoulder air bag 3.

[0045] It should be noted that, in order not to affect normal driving safety, the shoulder airbag 3 will be forcibly deflated and converted to a folded state during the driving of the vehicle. Specifically, the central control system of the vehicle can send a driving instruction to the controller 5, and the controller 5 determines that the shoulder airbag 3 needs to be forcibly folded according to a preset program, so it sends a deflation control instruction to the first air valve 22, and the first air pump 21 deflates the shoulder airbag 3, so as to ensure the safety of the driver and passenger 6.

[0046] Based on the above structure, see Figures 1 to 3 The car seat also includes a hip airbag 4 embedded between the seat cushion 1 and the seat back 2. The hip airbag 4 can be stretched to lie flat on the upper part of the seat back 2 in an inflated state to support the hips and lower waist of the driver and passenger 6.

[0047] In this embodiment, a buttocks airbag 4 is also provided on the seat cushion 1. The buttocks airbag 4 can effectively connect the seat cushion 1 and the seat back 2, so that a flat connecting surface is formed between the two, thereby avoiding step difference, thereby effectively supporting the buttocks and lower waist of the driver and passenger 6, thereby improving the comfort in the lying state.

[0048] In some possible implementations, the above-mentioned characteristic seat cushion 1 is adopted as follows Figure 1 , Figure 3 and Figure 5 See the structure shown. Figure 1 , Figure 3 and Figure 5 The seat cushion 1 is provided with a second air pump 41 which is connected with the buttocks air bag 4 and is used to inflate the buttocks air bag 4 or release the gas in the buttocks air bag 4. The second air pump 41 is provided with a second air valve 42 which is electrically connected with the controller 5. The controller 5 is used to send an inflation command or a deflation command to the second air valve 42.

[0049] Similarly, the hip airbag 4 is connected to a second air pump 41 which can inflate and deflate the hip airbag 4 . When the hip airbag 4 is folded, it can be embedded on the seat cushion 1 , or embedded between the seat cushion 1 and the seat back 2 .

[0050] When the driver and passenger 6 switches to a lying position, the hip airbag 4 and the shoulder airbag 3 are inflated synchronously until they are in the open state. At this time, the hip airbag 4 can be laid flat on the upper part of the seat cushion 1 near the seat back 2 to achieve the connection between the seat cushion 1 and the seat back 2. Combined with the use of the shoulder airbag 3, the comfort of the driver and passenger 6 in the lying state can be further improved. The combination of the hip airbag 4 and the shoulder airbag 3 can meet the needs of the driver and passenger 6 to rest in a lying position by adjusting the seat profile, thereby improving the comfort of the driver and passenger 6.

[0051] In some embodiments, the seat cushion 1 and the seat back 2 may be formed as follows: Figure 1 See the structure shown. Figure 1 The seat cushion 1 and the seat back 2 are rotatably connected, and an installation gap for accommodating a hip airbag 4 is formed between the seat cushion 1 and the seat back 2. The hip airbag 4 is arranged in the installation gap and extends laterally along the rear side wall of the seat cushion 1.

[0052] In this embodiment, when the driver and passenger 6 switch between the sitting and lying positions, the opening angle between the seat cushion 1 and the seat back 2 changes. An installation gap is formed between the seat back 2 and the seat cushion 1 that are rotatably connected to each other, and the hip airbag 4 can be installed in the above installation gap. At the same time, the hip airbag 4 extends laterally along the rear side wall of the seat cushion 1 to achieve the extension in the width direction of the seat cushion 1, so that the hip airbag 4 can be smoothly laid to the preset position when it is opened laterally, and it is also convenient to connect the second air pump 41 below with the hip airbag 4, so as to achieve reasonable use of space.

[0053] In some embodiments, the shoulder airbag 3 and hip airbag 4 described above can be used as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 When the shoulder airbag 3 and the hip airbag 4 are in the inflated state respectively, the thickness of the shoulder airbag 3 gradually increases from bottom to top, and the thickness of the hip airbag 4 gradually increases from front to back.

[0054] In this embodiment, in order to meet the support requirements of the head, shoulders, buttocks and waist of the human body in a lying state, the thickness of the shoulder airbag 3 and the buttocks airbag 4 is designed to a certain extent. The thickness of the shoulder airbag 3 gradually increases from bottom to top, so that the supporting height from the shoulders and neck to the head of the human body in the lying state is raised sequentially. At the same time, the thickness of the buttocks airbag 4 gradually increases from front to back, so that the supporting height from the buttocks to the waist of the human body in the lying state is gradually raised. The above thickness changes make the overall surface of the car seat form a relatively flat surface, which can effectively fit the human body and meet the comfort requirements of the driver and passenger 6 in the lying state.

[0055] In some possible implementations, the above-mentioned characteristic seat back 2 is adopted as follows Figures 1 to 4 See the structure shown. Figures 1 to 4 The seat back 2 includes a back body 23 and a headrest 24 disposed above the back body 23 , and an embedding hole 25 for accommodating the shoulder airbag 3 is provided between the headrest 24 and the back body 23 .

[0056] In this embodiment, the backrest body 23 and the headrest 24 form the entire seat back 2. There is an embedding hole 25 for installing the shoulder airbag 3 between the backrest body 23 and the headrest 24. This area forms a space for accommodating the shoulder airbag 3, avoiding structural changes to the seat back 2 caused by setting up another area for embedding the shoulder airbag 3, ensuring the safety and comfort of the driver and passenger 6 in the sitting state, and realizing the rational use of space.

[0057] Based on the same inventive concept, the embodiment of the present application further provides a car, the car comprising a car seat. The car can meet the needs of the driver and passenger 6 to lie down and rest by adjusting the seat profile, while meeting the safety of the driver and passenger 6 sitting posture, thereby improving the technological sense of the car and the comfort of the driver and passenger 6.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
