[0041] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0042] The ordinal numbers used in this article, such as first and second, are used to distinguish different parts with the same name and do not indicate a specific order or primary / secondary relationship.
[0043] The directional terms "front," "rear," "left," and "right" used in this document are defined based on the viewpoint of a user sitting in the rear seat of a car. Taking the car as a reference, the rear seats are generally arranged along the width of the vehicle; the front-rear direction can also be understood as the length direction, and the left-right direction can also be understood as the width direction. It is understood that the use of directional terms is merely for clarity and convenience in describing the technical solution and does not constitute a limitation on the scope of protection.
[0044] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the rear seats of a car in a first usage mode according to an embodiment provided in this application. Figure 2 This is a schematic diagram of the structure of the rear seats of a car in a second usage mode according to one embodiment of this application. Figure 3 The diagram illustrates the switching process of the rear seats of a car from a first usage mode to a second usage mode in a specific embodiment. The first usage mode can be understood as an adult usage mode, and the second usage mode can be understood as a child usage mode.
[0045] In this implementation plan, the rear seat of the car includes a seat frame 10, a seat cushion 30, an adult seat back 20, and a child seat back 40.
[0046] The adult seat backrest 20 is installed on the rear side of the seat frame 10, and the seat cushion 30 is located on the front side of the adult seat backrest 20. The seat cushion 30 can be supported by the seat frame 10.
[0047] The front side of the seat cushion 30 is rotatably connected to the front side of the seat frame 10, and the seat cushion 30 can be flipped away from or towards the adult seat back 20. In a specific configuration, the axis of rotation of the seat cushion 30 can extend in the left-right direction (i.e., the vehicle width direction).
[0048] The rear side of the child seat backrest 40 is rotatably connected to the rear side of the seat frame 10. The child seat backrest 40 can be flipped away from or towards the adult seat backrest 20 to switch between a hidden position and a used position. In the hidden position, the child seat backrest 40 is located under the seat cushion 30. In the used position, the child seat backrest 40 is upright and located in front of the adult seat backrest 20. In specific configurations, the axis of rotation of the child seat backrest 40 can also extend in the left-right direction (i.e., the vehicle width direction).
[0049] The rear side of the seat cushion 30 has a clearance notch 301, and in the use position, the child seat backrest 40 extends upward from the clearance notch 301.
[0050] When the child seat backrest is in the hidden position at 40 degrees, the rear seats of the car are in a position similar to... Figure 1The first usage mode shown is the adult usage mode. In this mode, the adult seat backrest 20 and seat cushion 30 form an adult seat for adult passengers. When the child seat backrest 40 is in the usage position, the rear seats of the car are in the position shown. Figure 2 The second usage mode shown is the child usage mode, in which the child seat backrest 40 and seat cushion 30 form a child seat that can be used by child passengers.
[0051] It should be noted that the upright position of the child seat backrest 40 in the usage position includes both the position where the child seat backrest 40 is parallel to the vertical direction and the position where the child seat backrest 40 is at a certain angle to the vertical direction. As long as the child seat backrest 40 and seat cushion 30 can form a seating position for a child in this position, it is acceptable. Alternatively, it can be understood as the child seat backrest 40 being in a roughly upright position in the usage position. (Reference) Figure 3 When switching from the first usage mode to the second usage mode, the rear seats of this car can be operated as follows:
[0052] like Figure 3 As shown in (a), the child seat backrest 40 of the rear seat of the car is in a hidden position. At this time, the seat cushion 30 and the adult seat backrest 20 are combined to form an adult seat.
[0053] like Figure 3 As shown in (b), the seat cushion 30 is flipped around its front axis of rotation, so that the seat cushion 30 is flipped forward, that is, flipped away from the adult seat back 20. At this time, the seat frame 10, which was originally covered by the seat cushion 30, is exposed, which makes it easy to flip the child seat back 40 located under the seat cushion 30. Figure 3 The curved arrow in (b) indicates the flipping direction of the seat cushion 30;
[0054] like Figure 3 As shown in (c), the child seat back 40, which was originally located under the seat cushion 30, is flipped backward so that the child seat back 40 is in an upright position. At this time, the child seat back 40 is close to the adult seat back 20. Figure 3 The curved arrow in (c) indicates the direction in which the child seat backrest 40 flips;
[0055] like Figure 3 As shown in (d), the seat cushion 30 is then flipped backward to the usage position supported by the seat frame 10. Since the rear side of the seat cushion 30 has an avoidance notch 301 that adapts to the child seat backrest 40, it can be combined with... Figure 2 Understood, so the repositioning of the seat cushion 30 will not interfere with the child seat backrest 40. At this time, the child seat backrest 40 and the seat cushion 30 cooperate to form a child seat. Figure 3The curved arrow in (d) indicates the flipping direction of the seat cushion 30.
[0056] When the back seat of the car needs to be moved Figure 3 (d) shows the second usage mode switching to Figure 3 In the first usage mode shown in (a), the operation process is as follows: flip the seat cushion 30 away from the adult seat back 20 to facilitate flipping the child seat back 40 to the hidden position, and then flip the seat cushion 30 towards the adult seat back 20 to restore it to the usage position.
[0057] The above solution integrates a flip-up child seat backrest 40 into the rear seat of the car, and the seat cushion 30 is also flip-up to facilitate changing the position of the child seat backrest 40. When the child seat is needed, simply flip the seat cushion 30 to flip the child seat backrest 40 from its hidden position to its usable position; when the child seat is not needed, simply flip the seat cushion 30 to flip the child seat backrest 40 from its usable position to its hidden position. This rear car seat functions as a child seat, and the child seat backrest 40 can be hidden under the seat cushion 30 when not in use, taking up little space, making it convenient to use and store, eliminating the need for users to purchase a separate child seat.
[0058] When the child seat backrest 40 is flipped to the hidden position, it is located under the seat cushion 30 and does not occupy the space of the seat cushion 30. It can be understood that the child seat backrest 40 is inside the seat frame 10 when it is in the hidden position.
[0059] Please refer to this as well. Figure 4 , Figure 4 This is an exploded view of the child seat backrest and child seat adjuster assembly in a specific embodiment.
[0060] In this embodiment, the rear seat of the car also includes a child seat adjuster assembly 50, and the child seat backrest 40 is rotatably connected to the rear side of the seat frame 10 through the child seat adjuster assembly 50.
[0061] In a specific implementation, the child seat backrest 40 includes a child seat backrest body 41 and a child seat backrest frame 42; wherein, the child seat backrest body 41 may include a backrest core and a backrest cover, the backrest core may be a foam material commonly used for backrests, and the backrest cover covers the outer periphery of the backrest core; the child seat backrest frame 42 is inserted into the child seat backrest body 41 and plays a supporting role.
[0062] In a specific implementation, the child seat adjuster assembly 50 includes two coaxially connected child seat adjusters 51. Each child seat adjuster 51 includes a first adjusting member and a second adjusting member that can rotate relatively coaxially. The first adjusting member and the second adjusting member are respectively fixedly connected to a first connecting member 52 and a second connecting member 53. One of the first connecting member 52 and the second connecting member 53 is fixedly connected to the child seat backrest frame 42, and the other of the first connecting member 52 and the second connecting member 53 is fixedly connected to the seat frame 10.
[0063] When the child seat backrest 40 is rotated by external force, the connector and corresponding adjustment piece connected to the child seat backrest frame 42 will rotate relative to another connector and corresponding adjustment piece, thereby realizing the rotation of the child seat backrest 40 relative to the seat frame 10.
[0064] It should be noted that, in addition to the first and second adjusting components, the child seat adjuster 51 also includes other structures such as locking teeth, unlocking cams, and locking cams. The child seat adjuster 51 uses a common seat adjuster structure, which is a mature and readily available design. The detailed structural components and connections of the seat adjuster itself will not be elaborated further. The seat adjuster can achieve angle adjustment within a relatively large range (e.g., 0°~180°), meeting the need for the child seat backrest 40 to flip between the hidden and usable positions.
[0065] The two child seat adjusters 51 of the child seat adjuster assembly 50 are located on both sides of the child seat back body 41 in the left and right directions. Since the force required to flip the child seat back 40 is relatively small, the child seat adjuster assembly 50 can provide a first elastic member 54 between the first connector 52 and the second connector 53 of only one of the child seat adjusters 51 to facilitate the reset operation of the child seat back 40.
[0066] Of course, in other embodiments, both child seat adjusters 51 of the child seat adjuster assembly 50 may be provided with a first elastic element 54.
[0067] In the illustrated example, the first connector 52 is used to fix the child seat backrest frame 42, and the second connector 53 is used to fix the seat frame 10.
[0068] Two child seat adjusters 51 are coaxially connected via a first connecting shaft 56. The first adjuster, which is fixedly connected to the first connecting member 52, can rotate with the first connecting shaft 56. The second adjuster, which is fixedly connected to the second connecting member 53, is only fitted over the first connecting shaft 56 and cannot rotate with the first connecting shaft 56.
[0069] The child seat adjuster assembly 50 also includes a child seat adjustment handle 57, a first mounting bracket 551 and a second mounting bracket 552 for facilitating the installation of the first elastic element 54, and two first thrust members 58 for limiting the axial position of the first connecting shaft 56. These are described below in conjunction with... Figures 5 to 9 This describes the assembly method of the child seat adjuster assembly 50 and its assembly method with the child seat backrest.
[0070] In the illustrated example, the first elastic element 54 is located at the child seat adjuster 51 on the right side.
[0071] like Figure 5 As shown, the right-side adjustment portion of the child seat adjuster assembly 50 includes a child seat adjuster 51, a first connector 52, a second connector 53, a first mounting bracket 551, and a second mounting bracket 552.
[0072] During assembly, the first mounting bracket 551 can be fixedly connected to the first connector 52, and the second mounting bracket 552 can be fixedly connected to the second connector 53. The fixed connection between the first mounting bracket 551 and the first connector 52, as well as the fixed connection between the second mounting bracket 552 and the second connector 53, can be achieved by welding, which provides a good fixing effect.
[0073] The child seat adjuster 51 is then positioned between the first connector 52 and the second connector 53, so that the first connector 52 is fixedly connected to the first adjusting member of the child seat adjuster 51, and the second connector 53 is fixedly connected to the second adjusting member of the child seat adjuster 51. It can be understood that since the first adjusting member and the second adjusting member can rotate relative to each other, the first connector 52 and the second connector 53 can also rotate relative to each other.
[0074] Finally, the first elastic element 54 can be installed. One end of the first elastic element 54 is connected to the first mounting bracket 551, and the other end is connected to the second mounting bracket 551, forming the right-side adjustable section. In a specific implementation, the first elastic element 54 can be a leaf spring. A slot can be provided on the first mounting bracket 551, and the end of the first elastic element 54 can be fitted into the slot of the first mounting bracket 551. A limiting groove for assembling the first elastic element 54 can be provided on the second mounting bracket 552.
[0075] like Figure 6 As shown, the left adjustment portion of the child seat adjuster assembly 50 includes a child seat adjuster 51, a first connector 52, and a second connector 53. During assembly, the child seat adjuster 51 is positioned between the first connector 52 and the second connector 53. The first connector 52 is fixedly connected to the first adjustment component of the child seat adjuster 51, and the second connector 53 is fixedly connected to the second adjustment component of the child seat adjuster 51, forming the left adjustment portion.
[0076] like Figure 7 As shown, the aforementioned right-side and left-side angle adjustment parts are coaxially connected by a first connecting shaft 56. The two ends of the first connecting shaft 56 pass through the child seat angle adjusters 51 on both sides, and the first connecting shaft 56 is limited by two first thrust members 58 to limit the relative positions of the first connecting shaft 56, the right-side angle adjustment part, and the left-side angle adjustment part in the axial direction of the first connecting shaft 56.
[0077] The first connecting shaft 56 is connected to the first adjusting member of the child seat adjuster 51 in the circumferential direction, so that the first adjusting member and the first connecting shaft 56 can rotate together.
[0078] The right end of the first connecting shaft 56 extends beyond the right-side adjustment section to facilitate the subsequent installation of the child seat adjustment handle 57.
[0079] like Figure 8 As shown, the child seat backrest frame 42 is fixedly connected to the first connector 52 of the right-side angle adjustment part and the first connector 52 of the left-side angle adjustment part, and the child seat adjustment handle 57 is circumferentially limited to the right end of the first connecting shaft 56 so that the child seat adjustment handle 57 can rotate together with the first connecting shaft 56.
[0080] In practice, the child seat backrest frame 42 can be U-shaped, and the two side arms of the child seat backrest frame 42 are fixedly connected to the two first connecting pieces 52 respectively.
[0081] The child seat backrest frame 42 and the first connecting piece 52 can be fixed by welding, which is reliable and simple.
[0082] like Figure 9 As shown, the child seat backrest body 41 can finally be connected to... Figure 8 The child seat backrest frame 42 and child seat adjuster assembly 50 are assembled, and the child seat backrest body 41 is fitted over the child seat backrest frame 42. To facilitate the flipping operation of the child seat backrest 40, the child seat adjustment handle 57 is exposed. To facilitate the installation of the child seat adjuster assembly 50 and the seat frame 10, a portion of the second connector 53 is also exposed. Here, "exposed" refers to the child seat backrest body 41.
[0083] For ease of description, the following text will... Figure 9 The child seat backrest 40 and child seat adjuster assembly 50, which are assembled together, are referred to as the child seat backrest assembly.
[0084] Please refer to this as well. Figure 10 , Figure 10 This is a schematic diagram of the installation structure of the child seat backrest assembly and seat frame in a specific implementation.
[0085] In one implementation, a support shaft 11 extending in the left-right direction can be provided on the rear side of the seat frame 10. The two ends of the support shaft 11 can be supported and fixed by two support seats 12, and two mounting plates 13 are fixedly sleeved on the support shaft 11.
[0086] The two second connectors 53 of the child seat backrest assembly are respectively fixedly connected to the two mounting plates 13. In a specific implementation, the second connectors 53 and the mounting plates 13 can be detachably fixedly connected by fasteners 90 to facilitate replacement of the child seat backrest assembly as needed. The fasteners 90 can be bolts or the like.
[0087] In practical applications, users can flip the child seat backrest 40 using the child seat adjustment handle 57. When the child seat adjustment handle 57 is turned, the first connecting piece 52 and the first adjusting piece on the right side of the adjustment part rotate together and drive the first connecting shaft 56 to rotate, thereby driving the first connecting piece 52 and the first adjusting piece on the left side of the adjustment part to rotate synchronously, so that the child seat backrest frame 42 fixed with the first connecting piece 52 and the cover on the child seat backrest body 41 of the child seat backrest frame 42 flip together.
[0088] Please refer to Figure 11 and Figure 12 , Figure 11 This is an exploded view of the seat cushion and seat cushion adjuster assembly in a specific embodiment. Figure 12 This is a schematic diagram of the assembly of the seat cushion assembly in a specific embodiment.
[0089] In this embodiment, the rear seat of the car also includes a seat cushion adjuster assembly 60, and the front side of the seat cushion 30 is rotatably connected to the front side of the seat frame 10 through the seat cushion adjuster assembly 60.
[0090] In a specific implementation, the seat cushion 30 includes a cushion body 31 and a cushion frame 32; wherein, the cushion body 31 may include a cushion core and a cushion cover, with the cushion cover covering the outer periphery of the cushion core; the cushion frame 32 can be inserted into the cushion body 31 to provide support.
[0091] In a specific implementation, the seat cushion adjuster assembly 60 includes two coaxially connected seat cushion adjusters 61. Each seat cushion adjuster 61 includes a third and a fourth adjusting member that can rotate relatively coaxially. The third and fourth adjusting members are respectively fixedly connected to a third connector 62 and a fourth connector 63. A second elastic member 64 is provided between the third connector 62 and the fourth connector 63. One of the third connector 62 and the fourth connector 63 is fixedly connected to the seat cushion frame 32, and the other of the third connector 62 and the fourth connector 63 is fixedly connected to the front side of the seat frame 10.
[0092] When the seat cushion 30 is rotated by external force, the connector and the corresponding adjustment piece connected to the seat cushion frame 32 will rotate relative to the other connector and the corresponding adjustment piece, thereby realizing the rotation of the seat cushion 30 relative to the seat frame 10.
[0093] It should be noted that the seat adjuster 61, like the aforementioned child seat adjuster 51, adopts the structure of a conventional seat adjuster, which will not be described in detail here.
[0094] The two seat cushion adjusters 61 of the seat cushion adjuster assembly 60 are located on both sides of the seat cushion 30 in the left-right direction. Since the seat cushion 30 requires a large force when flipping, a second elastic member 64 is provided between the third connector 62 and the fourth connector 63 of the two seat cushion adjusters 61.
[0095] In the illustrated example, the third connector 62 is used for fixed connection with the seat cushion frame 32, and the fourth connector 63 is used for fixed connection with the seat frame 10.
[0096] Two seat cushion adjusters 61 are coaxially connected via a second connecting shaft 66. The third adjusting member, which is fixedly connected to the third connecting member 62, can rotate with the second connecting shaft 66. The fourth adjusting member, which is fixedly connected to the fourth connecting member 63, is only fitted onto the second connecting shaft 66 and cannot rotate with the second connecting shaft 66.
[0097] The seat adjustment assembly 60 also includes a seat adjustment handle 67, a third mounting bracket 651 and a fourth mounting bracket 652 for facilitating the installation of the second elastic element 64, and two second thrust members 68 for limiting the axial position of the second connecting shaft 66.
[0098] The seat cushion 30 and seat cushion adjuster assembly 60 assembled together are referred to here as the seat cushion assembly.
[0099] Combination Figure 11 and Figure 12 (a) When assembling the seat cushion assembly, the right and left adjustment parts of the seat cushion adjuster assembly 60 can be assembled separately first. Then, the right and left adjustment parts are assembled together via the second connecting shaft 66, and the second connecting shaft 66 is limited by two second thrust members 68. A third mounting bracket 651 is fixedly connected to the third connecting member 62 of both the right and left adjustment parts of the seat cushion adjuster assembly 60, and a fourth mounting bracket 652 is fixedly connected to the fourth connecting member 63 of both the right and left adjustment parts of the seat cushion adjuster assembly 60 to facilitate the installation of the second elastic member 64. The assembly of the right and left adjustment parts of the seat cushion adjuster assembly 60 can be referred to the assembly of the right adjustment part of the aforementioned child seat adjuster assembly 50, and will not be detailed here.
[0100] In the illustrated example, the rear seat of the car is a two-seater structure, with the child seat backrest 40 positioned on the left side of the two-seater structure. The seat cushion body 31 has a clearance notch 301 on its left side for engaging with the child seat backrest 40. The seat cushion frame 32 includes a first frame 321, a second frame 322, and a connecting plate 323. Both the first and second frames 321 are U-shaped.

[0110] For reference Figure 2 When the child seat backrest 40 is in use, the shoulder safety belt 71 can be restricted by the limiting member 43, thereby facilitating the safety protection of the child sitting in the child seat.
[0111] In practical applications, the rear seats of cars can also be equipped with abdominal seat belts 72. Combined with shoulder seat belts 71 and abdominal seat belts 72, they can better restrain the children in the car and provide better protection.
[0112] Combination Figure 2 and Figure 10 In one possible implementation, the limiting member 43 includes an annular body having an opening slit 431 for the shoulder harness 71 to pass through in order to confine the shoulder harness 71 within the annular body.
[0113] The shoulder safety belt 71 is generally made of soft woven material and is relatively thin. When using a child seat, the shoulder safety belt 71 can be inserted into the ring-shaped body through the opening 431 of the limiting member 43. When not in use, the shoulder safety belt 71 can be removed from the opening 431. It is easy to operate and has a simple structure.
[0114] In practice, the limiting component 43 can be made of plastic and fixed to the child seat backrest 40 by means of adhesive or fastener connection.
[0115] In other embodiments, the limiting member 43 may also adopt other structures, such as a snap-fit structure. The snap-fit structure includes a first snap-fit part and a second snap-fit part. The first snap-fit part can be fixed to the child seat back 40, and the second snap-fit part can be engaged or disengaged from the first snap-fit part. When not in use, the second snap-fit part is engaged with the first snap-fit part. When in use, the engagement between the second snap-fit part and the first snap-fit part can be released first, the shoulder safety belt 71 can be placed between the first snap-fit part and the first snap-fit part, and then the second snap-fit part can be engaged with the first snap-fit part.
[0116] In this embodiment, the rear seat of the car may further include a cushion 80, which is adapted to the clearance notch 301 of the seat cushion 30, and the cushion 80 can be inserted into the clearance notch 301. (See reference) Figure 1 It is understood that when the child seat is not in use, the child seat backrest 40 is in a hidden position, and the insert 80 can be inserted into the clearance notch 301 to avoid affecting the use by adult passengers, and also to maintain the aesthetics of the rear seat in the first use mode. When the child seat needs to be used, the insert 80 can be removed to avoid affecting the use of the child seat.
