Abstract
Description
Technical Field
[0001] This application belongs to the field of child car seat technology, specifically relating to rear-facing child car seats. Background Technology
[0002] Rear-facing child seats generally consist of a seat body, a base, and a vehicle mounting structure. The base is reliably installed via child seat anchor points in the rear of the vehicle or the seat belt. The seat body works in conjunction with the base to meet the reclining angle and seating posture needs of different age groups.
[0003] In high-energy impact scenarios such as frontal collisions, child seats are subjected to significant inertial loads. Due to factors such as carpet compression, vehicle seat deformation, and gaps in connecting parts, child seats may tilt forward or pitch and rotate noticeably. This forward tilt weakens the restraint and occupant retention effect and increases the risk of contact or even collision with the front seat back when front space is insufficient.

[0006] In some embodiments, the base includes: A fixing system, wherein the first guide member is connected to the fixing system; The housing has a bearing surface and a guide surface opposite to the bearing surface, the guide surface having a guide hole, the fixing system passing through the housing, and the first guide member passing through the guide hole.
[0007] In some embodiments, the rear-facing child seat includes a plurality of first guides, at least a portion of which are spaced apart along a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.
[0008] In some embodiments, the rear-facing child seat further includes a plurality of second guide members connected to the side of the seat body facing the base, with the first guide member passing through the second guide member, and portions of the plurality of second guide members spaced apart along the extending direction of the first guide member.
[0009] In some embodiments, the rear-facing child seat further includes a sliding support member connected to the side of the seat body facing the base, and a second guide member connected to the side of the sliding support member facing the base.
[0010] In some embodiments, the rear-facing child seat further includes an elastic element connected to the base and the seat body, the elastic element being configured to produce elastic deformation when the seat body moves along the first direction.
[0011] In some embodiments, the elastic element is configured to be compressed as the seat body moves in the first direction toward a direction away from the backrest.
[0012] In some embodiments, the elastic element is disposed on the side of the first guide member opposite to the seat body; The rear-facing child seat also includes a connector, which includes a first connecting part and a second connecting part. The first connecting part is connected to the seat body and is located on one side of the first guide along a third direction. The second connecting part is located on one side of the first guide along a second direction and is connected to the first connecting part.

[0013] In some embodiments, the rear-facing child seat includes a plurality of said elastic elements, at least a portion of which are spaced apart along the extension direction of the first guide.
[0014] In some embodiments, the rear-facing child seat further includes a sliding support member connected to the side of the seat body facing the base, and a connector connected to the side of the sliding support member facing the base.
[0015] Beneficial Effects: Compared with the prior art, the rear-facing child seat provided in this application includes a base, a first guide member, and a seat body. The base has a bearing surface for connecting with the seat cushion; the first guide member is connected to the base; the seat body is connected to the first guide member and is movable relative to the base in a first direction. The seat body includes a backrest and a seat portion connected to each other, with the backrest having an end portion away from the seat portion. The first guide member is configured to guide the seat body, and when the seat body moves in the first direction away from the backrest, it rotates the seat body so that the end portion moves in a second direction away from the bearing surface. The first and second directions are perpendicular. By providing a first guide member and guiding and rotating the seat body when it moves in the first direction, this application makes the seat body's movement trajectory include a component movement in the second direction. This reduces the travel in the first direction while meeting movement requirements, thus reducing the possibility of the seat body contacting or colliding with the backrest of the front seat in the fore-and-aft direction. Simultaneously, the upward movement of the backrest end along the second direction causes the seat body to tend towards an upright or raised posture, making it easier for the backrest to be positioned in front of the child's body in the first direction to provide support and cushioning. This improves the restraint stability for the child and reduces the likelihood of significant separation between the child and the seat body. Furthermore, during the steering rotation and lifting process, the seat body system may generate some work and energy dissipation, resulting in a more gradual change in the collision response history, which helps reduce the transient impact response level.

[0022] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.
[0023] Rear-facing child seats generally consist of a seat body, a base, and a vehicle mounting structure. The base is reliably installed via child seat anchor points in the rear of the vehicle or the seat belt. The seat body works in conjunction with the base to meet the reclining angle and seating posture needs of different age groups.
[0024] In high-energy impact scenarios such as frontal collisions, child seats are subjected to significant inertial loads. Due to factors such as carpet compression, vehicle seat deformation, and gaps in connecting parts, child seats may tilt forward or pitch and rotate noticeably. This forward tilt weakens the restraint and occupant retention effect and increases the risk of contact or even collision with the front seat back when front space is insufficient.
[0025] Rear-facing child seats refer to child seats installed in the opposite direction to the normal driving direction of the vehicle, meaning that the child in the rear-facing child seat faces forward in the normal driving direction of the vehicle.
[0026] To address the aforementioned technical problem of forward-leaning child seats, the first embodiment of this application provides a rear-facing child seat. (See [link to relevant documentation]). Figure 1 The rear-facing child seat includes a base 100, a first guide 200, and a seat body 300. The base 100 has a bearing surface 121 for connecting to a seat cushion. The first guide 200 is connected to the base 100. The seat body 300 is connected to the first guide 200 and is movable relative to the base 100 along a first direction X. The seat body 300 includes a backrest 310 and a seat portion 320 connected to each other. The backrest 310 has an end portion 311 away from the seat portion 320. The first guide 200 is configured to guide the seat body 300 and, when the seat body 300 moves along the first direction X in a direction away from the backrest, rotates the seat body 300 such that the end portion 311 moves along a second direction Y in a direction away from the bearing surface 121. The first direction X and the second direction Y are perpendicular.
[0027] Specifically, the first direction X is the front-to-back direction, and the second direction Y is the up-and-down direction. Since this child seat is a rear-facing seat, the seat body 300 moves along the first direction X in a direction away from the backrest, i.e., the seat body 300 moves forward. Furthermore, since the base 100 is below the seat cushion, the seat body 300 can only be positioned above the base 100. Therefore, the end 311 moves along the second direction Y in a direction away from the bearing surface 121, i.e., the end 311 moves in a higher direction.
[0028] Specifically, the base 100 is equipped with an ISOFIX connection device, which is used to connect to the lower fixing point on the seat body 300 to connect the rear-facing child seat to the vehicle seat. The bearing surface 121 of the base 100 is connected to the seat cushion of the vehicle seat, and the base 100 is also connected to the backrest of the vehicle seat.
[0029] Please see Figure 2 and Figure 3 ,in Figure 2 This is a side view of the seat body 300 when it is not moved. Figure 3 This is a side view of the seat body 300 when it has moved to its limit position along the first direction X. Figure 3 The seat body 300 in the middle is compared to Figure 2 The seat body 300 is located further forward, and the distance between the end 311 of the backrest 310 and the base 100 in the second direction Y is greater, that is, in Figure 2 and Figure 3 During the forward movement of the seat body 300, under the action of the guide, the seat body 300 not only moves forward but also rotates counterclockwise.
[0030] The first guide member 200 drives the seat body 300 to rotate along a rotation axis extending in a third direction Z, specifically, the third direction Z is the left and right direction of the vehicle.
[0031] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The first guide member 200 extends in an arc shape in order to align with and rotate the seat body 300 during linear movement.
[0032] Firstly, in the above embodiment, the seat body 300 can move relative to the base 100 along a first direction X, and the first guide member 200 guides the seat body 300 and rotates the seat body 300 during this movement, thereby causing the end portion 311 to move away from the bearing surface 121 along a second direction Y perpendicular to the first direction X. Since this motion trajectory includes an upward component of the second direction Y, the displacement of the seat body 300 is jointly borne by the two directional components, and the stroke in the first direction X is relatively reduced, thereby reducing the possibility of the seat body 300 contacting or colliding with the backrest of the front seat in the front-rear direction.
[0033] Secondly, in the above embodiment, the upward movement of the backrest end 311 changes the posture of the seat body 300 from a reclining position to a more upright or raised position. This makes it easier for the backrest 310 to be positioned in front of the child's body in the first direction X, providing effective support and thus inhibiting the relative displacement between the child and the seat body 300 and reducing the possibility of separation. It is understood that when the seat body 300 is reclining, the backrest 310's restraint on the child mainly relies on the friction between the backrest 310 and the child. When the seat body 300 is upright, it can directly prevent the child from moving forward relative to the seat body 300. Simultaneously, during a collision, the backrest 310 provides effective support and relief to the child's torso, potentially reducing the tendency for spinal bending or stretching, thus having a potentially beneficial effect on reducing the risk of spinal-related forces during a collision. Similarly, it can be understood that when the seat body 300 is tilted towards a supine position, the child's head is located in front of the neck. During a collision, because the child's torso is restrained within the seat body 300 and relatively stationary, the head, due to its large mass and lack of external restraint in the forward / backward direction, will experience traction between the head and neck, and consequently, between the neck and chest, potentially leading to head and chest injuries. However, when the seat body 300 changes from a supine to an upright position, the head and neck's position changes from forward / backward to vertical. During a collision, the forward movement of the head is restricted by the backrest 310, reducing the likelihood of traction between the head and neck, and between the neck and chest. This lowers the risk of head, neck, and chest injuries, thus improving child protection.
[0034] In addition, in the above embodiments, the arc-shaped first guide member 200 can provide an arc-shaped trajectory. The continuity of the arc-shaped trajectory allows the seat body 300 to rotate continuously with displacement, making the rotation process smoother and the movement more predictable, which helps to reduce the tendency of the guide pair to be off-center and stuck.
[0035] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 6 The base 100 includes a fixing system 110 and a housing 120. A first guide member 200 is connected to the fixing system 110. The housing 120 has a bearing surface 121 and a guide surface 122 opposite to the bearing surface 121. The guide surface 122 has a guide hole 123. The fixing system 110 passes through the housing 120, and the first guide member 200 passes through the guide hole 123.
[0036] The fixing system 110 is ISOFIX, i.e., a child seat fixing system 110, through which the rear-facing child seat is connected to the vehicle seat. It is understood that the fixing system 110 is the primary load-bearing component.
[0037] In other embodiments, a portion of the seat body 300 passes through the guide hole 123 and is connected to the first guide member 200.
[0038] Specifically, the guide hole 123 extends along the first direction X.
[0039] In the above embodiments, the first guide member 200 is connected to the fixing system 110, and the guiding reference of the first guide member 200 is directly provided by the fixing system 110, so that the installation reference of the first guide member 200 is more directly related to the fixed path of the vehicle. Since the fixing system 110 is the main force-bearing component, it is beneficial to maintain the positional stability of the first guide member 200 under high load conditions, so that the guiding movement and posture change of the seat body 300 are closer to the preset relationship and the consistency is improved.
[0040] Meanwhile, the fixing system 110 passes through the housing 120 to form a more direct force channel, which can reduce the proportion of the main load borne by the housing 120 and reduce the adverse effects of the deformation of the housing 120 on the guiding accuracy.
[0041] In some embodiments, please refer to Figure 4 and Figure 5 The rear-facing child seat includes a plurality of first guide members 200, at least some of which are spaced apart along a third direction Z, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0042] In some embodiments, the rear-facing child seat includes two parallel first guide members 200 spaced Z-spaced along a third direction.
[0043] In the above embodiments, by setting multiple first guide members 200 and distributing them at least partially along the third direction Z, the guiding constraint of the seat body 300 relative to the base 100 is transformed from a single-point constraint to a multi-point, laterally expanded constraint. Multi-point guidance can collectively limit the lateral displacement and vertical deflection of the seat body 300 under motion or load, improving torsional resistance and reducing the possibility of jamming caused by off-center loading.
[0044] Meanwhile, the load is distributed among multiple guide members, which relatively reduces the peak load and contact pressure of a single guide member, thereby improving the load-bearing capacity and durability of the guide mechanism. Because yaw is suppressed, the coupling relationship between the displacement and rotation of the seat body 300 is closer to the preset value, and the consistency between the upward movement of the end 311 and the attitude correction is improved, thus making the reduction of the first direction X-stroke and the forward intrusion control effect more stable.
[0045] In some embodiments, please refer to Figure 4 and Figure 5The rear-facing child seat also includes multiple second guide members 400. The second guide members 400 are connected to the side of the seat body 300 facing the base 100. The first guide member 200 passes through the second guide member 400. Parts of the multiple second guide members 400 are spaced apart along the extension direction of the first guide member 200.
[0046] The second guide 400, which is inserted through the first guide 200, can move relative to the first guide 200 along the extension direction of the first guide 200.
[0047] In the above embodiments, multiple second guide members 400 are connected to the first guide member 200 and are arranged at intervals along the extension direction of the first guide member 200, so that the guiding constraint is changed from a single-point connection to a multi-point connection distributed along the length direction, thereby suppressing swaying, pitching and torsional swaying during the guiding process and improving the stability and repeatability of the guiding motion.
[0048] Furthermore, multi-point coordination makes it easier to distribute the guiding load, reducing the peak contact pressure and off-center load at a single mating point. This reduces the tendency for localized wedging, jamming, and abnormal wear, and improves smoothness and durability. Due to the improved guiding accuracy, the coupling relationship between the seat body 300 movement and posture changes is closer to the preset value, making the vertical movement more consistent, and thus making the effective travel control in the forward and backward directions more stable.
[0049] In some embodiments, please refer to Figure 4 and Figure 5 The rear-facing child seat includes multiple first guide members 200 spaced apart along the third direction Z. Each first guide member 200 is connected to multiple second guide members 400 that are simultaneously connected to the seat body 300, in order to further suppress yaw, pitch swing and torsional swing during the guiding process and improve the stability and repeatability of the guiding motion.
[0050] In some embodiments, please refer to Figure 4 and Figure 5 The rear-facing child seat also includes a sliding support 500, which is connected to the side of the seat body 300 facing the base 100, and a second guide 400 is connected to the side of the sliding support 500 facing the base 100.
[0051] Understandably, the seat body 300 needs to form a space that can accommodate and restrain a child, and also needs to accommodate cushioning components such as soft pads. The seat body 300 is relatively large. If the second guide 400 is directly connected to the bottom of the seat body 300, the large volume of the base 100 and the seat body 300 will limit the gap or space between the base 100 and the seat body 300. The entry angle, swing stroke and force direction of the assembly tool in the narrow space are limited, thereby reducing the flexibility of the assembly tool and increasing the difficulty of alignment and fastening, resulting in greater difficulty in assembling rear-facing child seats.
[0052] In the above embodiment, by providing a small sliding support 500 on the side of the seat body 300 near the base 100, the difficulty of connecting the sliding support 500 and the second guide 400 is reduced, and then the sliding support 500 is connected to the seat body 300, thereby improving the assemblability and assembly consistency of the rear-facing child seat.
[0053] In some embodiments, please refer to Figure 4 and Figure 5 The rear-facing child seat also includes an elastic element 600, which is connected to the base 100 and the seat body 300 respectively. The elastic element 600 is configured to produce elastic deformation when the seat body 300 moves along the first direction X.
[0054] Understandably, the elastic element 600 can convert at least part of the kinetic energy of the seat body 300 into elastic potential energy.
[0055] In the above embodiments, by setting elastic members 600 that connect the base 100 and the seat body 300 respectively, and by causing the elastic members 600 to undergo elastic deformation when the seat body 300 moves along the first direction X, the load process of the seat body 300 can be extended and made more gradual, and the peak impact force or peak acceleration shows a decreasing trend, thereby achieving a buffering effect.
[0056] In addition, in the above embodiments, the elastic member 600 can also achieve the restraint effect on the seat body 300 by applying elastic reaction force or tension to the seat body 300 when the load is small, thereby reducing the possibility that the seat body 300 moves too much along the first guide member 200 in non-collision situations and improving the riding comfort.
[0057] In some embodiments, please refer to Figure 4 and Figure 5 The elastic element 600 is configured to be compressed when the seat body 300 moves in the first direction X toward a direction away from the backrest.
[0058] Specifically, one end of the elastic member 600 connected to the base 100 is located in front of the other end of the elastic member 600 connected to the seat body 300, so that the elastic member 600 can be compressed when the seat body 300 moves forward.
[0059] Understandably, the elastic element 600 is configured to operate under pressure during a collision, making the mechanical response of the elastic element 600 more predictable when the seat body 300 moves forward, and the force at the connection point more stable, which can improve the reliability of rear-facing child seats.
[0060] In the above embodiments, by restricting the operation of the elastic element 600 when the seat body 300 moves forward after a collision, the force and connection state of the elastic element 600 can be made more stable, thereby improving the reliability of the action.
[0061] In some embodiments, the elastic element 600 is configured to be compressed when the seat body 300 moves away from the backrest along the first direction X, and the elastic element 600 is configured to be in a compressed state when no collision occurs. That is, the elastic element 600 is pre-compressed when no collision occurs, so that the seat body 300 can be subjected to the elastic force generated by the elastic element 600 when no collision occurs, thereby enabling the elastic element 600 to limit the seat body 300 along the second direction Y.
[0062] In some embodiments, the pressure exerted by the seat body 300 on the elastic member 600 is formed by the component of gravity of the seat body 300, the sliding support 500, the first guide 200, and the connector 700.
[0063] In some embodiments, please refer to Figure 4 and Figure 5 The elastic element 600 is disposed on the side of the first guide 200 away from the seat body 300; the rear-facing child seat also includes a connector 700, which includes a first connecting part 710 and a second connecting part 720. The first connecting part 710 is connected to the seat body 300 and is located on the side of the first guide 200 along the third direction Z. The second connecting part 720 is located on the side of the first guide 200 along the second direction Y and is connected to the first connecting part 710 and the elastic element 600. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0064] In some embodiments, please refer to Figure 4 and Figure 5 The connector 700 and the second guide 400 are spaced apart along the first direction X.
[0065] Firstly, in the above embodiments, by providing a connector 700 to connect the elastic member 600 and the seat body 300, the connection point between the elastic member 600 and the seat body 300 can be moved to a more advantageous spatial position and the distance between the two mounting points can be increased. This allows for an increase in the effective length of the elastic member 600 and a larger usable compression stroke. Due to the increased cushioning stroke, the elastic member 600 can complete energy conversion and gradually build up reaction force over a longer displacement range during the movement of the seat body 300 along the first direction X. In other words, it can increase the proportion of cushionable movement of the seat body 300, thereby improving the effect of the elastic member 600.
[0066] Secondly, in the above embodiments, the connector 700 includes a first connecting portion 710 located on the side of the first guide 200 and a second connecting portion 720 located below the first guide. This arrangement allows the elastic member 600 to be disposed below the first guide 200, thereby enabling the elastic member 600 to utilize the space between the fixing system 110 and the first guide 200, reducing the possibility of interference between the elastic member 600 and components such as the first guide 200, the second guide 400, and the sliding support 500 in a confined space.
[0067] In some embodiments, please refer to Figure 4 and Figure 5 The rear-facing child seat includes a plurality of elastic elements 600, at least some of which are spaced apart along the extension direction of the first guide 200.
[0068] In some embodiments, at least two elastic members 600 are disposed below each first guide member 200 and spaced apart along a first direction X.
[0069] Firstly, in the above embodiments, multiple elastic elements 600 are spaced apart along the extension direction of the first guide element 200, so that the buffer reaction force is distributed in the stroke direction and the multi-point sharing is achieved, thereby reducing the local peak load and stress concentration tendency caused by single-point bearing, and improving the structural reliability and durability.
[0070] Secondly, in the above embodiments, the distributed elastic action makes it easier to achieve gradual changes in the reaction force establishment process, so that the impact response exhibits a smoother buffering characteristic and has a trend effect of reducing the peak impact response. At the same time, it can reduce the adverse effects of off-center loading on the guide pair, improve the consistency of guide motion, and improve the stability and redundancy of the buffering effect under different working conditions.
[0071] In some embodiments, please refer to Figure 4 and Figure 5The rear-facing child seat also includes a sliding support 500, which is connected to the side of the seat body 300 facing the base 100, and a connector 700 is connected to the side of the sliding support 500 facing the base 100.
[0072] In the above embodiment, the connector 700 is disposed on the side of the sliding support 500 facing the base 100, so that the connector 700 has a clearer assembly reference and force reference, which makes it easier for the connector 700 and the sliding support 500 to form a sub-component and can reduce the assembly difficulty of directly aligning and fastening the large seat body 300 in a small space through pre-assembly, thereby improving assembly efficiency and assembly consistency.
[0073] The foregoing has provided a detailed description of a rear-facing child seat according to the embodiments of this application. Specific examples have been used in this application to illustrate the principles and implementation methods of this application.
