Description

Technical Field

[0001] In summary, this disclosure relates to child car seat systems and has particular (though not exclusive) practicality in providing child car seat systems with improved side-impact protection features. Background Technology

[0002] In some countries, laws require infants, toddlers, and children under a certain age, height, and / or weight to use supplemental car seats when traveling in vehicles. These car seats typically improve children's safety while in a vehicle, especially in the event of a collision, compared to using a typical seatbelt alone. The shape, size, and arrangement of car seats generally depend on the child's age and / or height. Children from birth to approximately 1 year old may require a so-called infant car seat, from approximately 1 year to approximately 4 years old they may require a so-called toddler car seat, and from approximately 4 years old until the child no longer needs a car seat, a so-called booster seat may be required.

[0003] Typical car seats and associated seatbelt systems are designed for adults and are therefore not ideal for children. A primary function of child car seats is to improve a child's safety and survival in a vehicle crash scenario, typically by protecting the child and reducing the peak impact force applied to them. Previously known car seat systems utilize significant amounts of engineered or high-performance foams and other padding, which can substantially increase the cost of such systems. Consequently, the use of these foams and padding reduces the accessibility of car seat systems.

[0004] Child car seat systems typically need to be compatible with a wide range of vehicles, including various car brands and models. To ensure broad compatibility, regulatory agencies may impose a three-dimensional space or box within which the child car seat must fit. An example of such regulation is UN ECE R129 / 03. However, due to the varying dimensions of vehicle seats and interiors, there is often extra space around the child car seat when it is installed. Deployable structures, such as folding wings, are known to be used to limit the distance between the child car seat and the vehicle interior (e.g., the inner surfaces of the doors). Deployable devices can allow the use of this extra space to reduce the number of collisions and can improve the vehicle's crash characteristics. However, deployable devices are generally not used in regulatory testing because their deployment would imply that the child car seat no longer fits within the three-dimensional space or box mandated by the regulator. Furthermore, installers and users of child car seats, such as parents or caregivers, may forget to deploy the deployable device or may deploy it incorrectly. Additionally, the shape, size, and spacing of the door interiors vary significantly between brands and models; therefore, the effectiveness of deployable devices depends on the vehicle brand and model.

[0005] Furthermore, it is not uncommon for children to experience so-called travel sickness or motion sickness, or other forms of discomfort, while traveling by car. Problems causing discomfort may be triggered and / or worsened when the vehicle is turning. Therefore, improved cornering characteristics are needed to increase comfort.

[0006] Various aspects of this disclosure seek to provide an automotive seat system to mitigate or reduce the severity of the aforementioned problems, and to provide a minor automotive seat system with improved cornering comfort and side impact protection features. Summary of the Invention

[0007] According to a first aspect of this disclosure, a child car seat system is provided, comprising: a docking module configured to be fixedly connected to a vehicle seat; a child carrier module configured to accommodate a child therein, the child car seat system being configured such that the child carrier module is rotatable about a rotation axis within the docking module; and a rotation stop selectively operable to restrict rotation of the child carrier module relative to the docking module about the rotation axis; wherein the rotation stop is compressible in the rotational direction about the rotation axis.

[0008] In this way, the rotation of the child-carrying module caused by cornering forces or side impacts is counteracted by a compressible rotation stop, thereby providing a more comfortable ride or reducing peak impact forces. This improves the comfort and / or safety of the minor.

[0009] The term “minor” as used in this article may refer to an infant, toddler, or child.

[0010] A child car seat system can be a system configured and designed to be secured to a vehicle and allow a child to sit in it. A child car seat system can be modified to resemble a typical vehicle seat designed for adult use to improve the suitability of the vehicle seat for child use.

[0011] The docking module being attached to the vehicle seat can mean that the docking module is detachably or non-detachably attached to the vehicle seat or vehicle so that the docking module can be placed on the vehicle seat.

[0012] The fact that the child carrier module can rotate about a rotation axis within the docking module means that the child carrier module can be rearranged relative to the docking module by rotating it relative to the docking module or a portion thereof. The docking module can be multi-part, with a first part, such as a bracket portion, attached to the child carrier module and rotatable relative to a second part (such as a base portion). The rotation axis can be arranged substantially perpendicular to the docking module attached to the vehicle seat. The child carrier module can rotate between a side-facing position and a front-and-rear position.

[0013] A rotation stop can be a component configured to engage or interconnect with a child carrier module and a docking module to limit relative rotation between the child carrier module and the docking module. The rotation stop may be located on the docking module and configured to selectively engage with the child carrier module. Alternatively, the rotation stop may be located on the child carrier module and configured to selectively engage with the docking module. Preferably, the docking module is multi-part, wherein a first part of the docking module is rotatable relative to a second part of the docking module, and the rotation stop is configured to limit rotation of the first part relative to the second part. The child carrier module may be attached to either the first or the second part, and the other of the first and second parts may be attached to a vehicle seat.

[0014] The selective operability of the rotary stop to limit the rotation of the minor carrier module relative to the docking module about the rotation axis means that the user can operate, engage, or drive the rotary stop to limit the rotation of the minor carrier module or not limit its rotation. Restricted rotation may mean that rotation is not completely stopped, but a smaller degree of rotation is allowed with the rotary stop compared to having no rotary stop. A compressed rotary stop allows for a relatively small amount of rotation.

[0015] A swivel stop can compress in the direction of rotation about its axis of rotation. This may mean that the swivel stop is configured to compress, bend, or otherwise allow relatively small rotation of the child carrier module relative to the docking module when a force or torque is applied to the child car seat system. Allowing relatively small rotation may mean that, in cornering or side-impact collision scenarios, the force applied to the child located in the child carrier module can spread over a longer timeframe, thus reducing the maximum or peak force applied to the child. Reducing the maximum or peak force applied to the child improves safety and comfort.

[0016] When a minor is placed inside, the center of gravity of the minor-bearing module can be spaced apart from the rotation axis. Thus, external forces applied to the system can cause torque and rotation of the minor-bearing module and the minor around the rotation axis. The torque and rotation of the minor-bearing module can ultimately be partially or completely offset by a rotation stop to reduce the peak force or multiple peak forces applied to or experienced by the minor. This reduces the severity of any injury suffered by the minor.

[0017] The minor carrying module may include a seat portion attached to the backrest portion via a locking hinge having two locking positions, such that the minor carrying module can be configured in an upright position and a reclining position, wherein in the upright position the seat portion and the backrest portion are tilted relative to each other at a first angle, and in the reclining position the seat portion and the backrest portion are tilted relative to each other at a second angle, the second angle being greater than the first angle.

[0018] In this way, the system can be used to transport minors in lying and sitting positions respectively, while the minor carrying module can be used to transport minors in an upright or sitting position while the vehicle is in motion.

[0019] A locking hinge with two locking positions can be any form of rotatable attachment, meaning that the two connected parts can rotate relative to each other while being secure in at least two relative tilts.

[0020] The first angle can be any angle that provides a standard sitting position. For example, the first angle can be in the range of 80° to 135°. The second angle can be any angle that provides a standard reclining position. For example, the second angle can be in the range of 135° to 180°. Other angles and ranges are also envisioned.

[0021] The seat portion may be part of a child car seat system, supporting the child's hips and legs. The backrest portion may be part of a child car seat system, supporting the child's back, arms, and head. As discussed herein, the backrest portion may or may not include a headrest.

[0022] The child car seat system can be configured so that the child-carrying module is adjustable within the docking module. The system's adjustability and flexibility mean that the car seat system can be used for children of various ages and heights. Furthermore, the child-carrying module can be adjusted within the docking module, such as reclining, to provide a more comfortable environment for the child. Additionally, the child car seat system can be sustainable. In particular, the child car seat system can adapt to the needs of growing children without requiring additional components or disposing of components as the child grows.

[0023] In this regard, adjustability can mean that the seat and backrest are relatively tiltable. Alternatively, adjustability can mean that the headrest portion of the child support module is adjustable in position relative to the backrest and / or the docking module. Alternatively, adjustability can mean that the child support module is tiltable within the docking module. Thus, the child support module can be adjusted within the docking module, especially as the child grows and increases in size. Accordingly, no additional components are needed to allow a growing child to continue using the system. Furthermore, no components need to be addressed as the child grows, thus providing a sustainable system. Additionally, the child support module can be the sole seat structure, providing a seat for the minor under all conditions of system use.

[0024] When the child-carrying module docks with the docking module, it prevents relative tilting between the seat and backrest. Thus, the child-carrying module can only dock with the docking module when positioned in an upright or sitting position. Therefore, during vehicle transport, the child can be positioned in a sitting position, which improves and enhances safety. Alternatively, when configured in an upright or reclining position, the child-carrying module is positioned to dock with the docking module.

[0025] The child support module is detachably secured in the upright and / or lying positions. Other and / or intermediate positions are conceivable. The locking hinge may include suitable locking positions as needed. This allows the child support module to be positioned at a comfortable tilt angle for the child. The locking hinge may include three, four, five, six, or any other number of locking positions to provide greater flexibility for the user to select the appropriate tilt angle. In particular, the locking hinge may have four locking positions, where the two locking positions described above relative to the upright and lying positions are the most extreme angles, and the other two are intermediate positions.

[0026] The child carrier module may also include a releasable locking mechanism configured to selectively secure the child carrier module in an upright or reclining position. The releasable locking mechanism may include an actuator for releasing the locking mechanism and allowing adjustment of the relative tilt of the seat portion and the backrest portion. The actuator may be incorporated into a seatbelt guide, which may be located behind the backrest portion.

[0027] The docking module may include a base portion and a housing portion rotatably attached to the base portion. The child carrier module may be configured to detachably dock to the housing portion. Thus, the child carrier module is rotatable relative to the base portion, and therefore rotatable relative to the vehicle seat, to which the base portion is attached. Accordingly, the child may be positioned facing forward, rearward, or somewhere in between. The child may be positioned forward or rearward for driving and may be moved to a lateral position to improve ease of placing or removing the child from the vehicle. The base portion may include an ISOFIX connector or ISOFIX assembly. The ISOFIX connector or assembly easily and securely connects the base portion to the vehicle. The ISOFIX assembly may include a telescopic arm with a ratchet and pawl system that can be fixed at multiple lengths. The telescopic arm may be biased towards an arrangement where the telescopic arm has a larger length. The ISOFIX assembly may include two vehicle locks configured such that both vehicle locks must be released to remove the ISOFIX assembly from the vehicle. An ISOFIX assembly may include one or more switches configured to operate when the ISOFIX assembly is connected to the vehicle, so that the connection state of the ISOFIX assembly is deterministic during use. An ISOFIX assembly may include two substantially identical arms positioned on either side of the vehicle seat. To install the system, the user positions one or more ISOFIX arms at their maximum length, secures one or more arms to the vehicle, and then pushes the child car seat system onto the vehicle seat, causing the length of one or more ISOFIX arms to decrease and be held at an optimal length by ratchet and pawl.

[0028] The child car seat system may also include a support leg. The support leg is rotatably attached to the docking module. The support leg can rotate between an extended position and a stored position, in which the support leg extends away from the docking module, and in the stored position, the support leg is adjacent to the docking module along its length. This allows the support leg to be extended and rested on the vehicle floor, or stored. The support leg can be extended when transporting a relatively young child in a rear-facing or forward-facing position. The support leg can be stored when transporting a relatively older child in a forward-facing position. The length of the support leg is adjustable and can be fixed at multiple lengths. The support leg may include a pressure sensor configured to determine the pressure applied to the free end of the support leg, so that the desired installation of the support leg can be determined during use. When the pressure measured by the pressure sensor is below a threshold pressure level, the system may be configured to provide visual and / or audible notification.

[0029] The support leg can be rotatably attached to the docking module via a retractable head. When the support leg is in the extended position, the retractable head can be configured to translate relative to the docking module along an axis substantially perpendicular to the longitudinal axis of the support leg. The retractable head can be positioned at the front of the docking module and can be rotated in and out of the front of the docking module. The child car seat system may also include a head lock configured to secure the retractable head relative to the docking module. The head lock can be configured to secure the retractable head in multiple extended positions. This allows the user to properly or preferably place the support leg in the vehicle's footwell. When the retractable head is fully retracted into the docking module, the outer housing of the retractable head can be flush with the outer housing of the docking module. Thus, the retractable head may be hidden or may not extend from the docking module when fully retracted. The retractable head may include a handle arranged such that a user can pull or push the handle to move the retractable head. The head lock may be incorporated into the handle. To extend the support leg, the support leg can be rotated to the extended position, and the retractable head is fully extended. The docking module can then be placed on the vehicle seat. The support leg can only be properly positioned when the retractable head is fully extended. The retractable head can be at least partially retracted to allow the support leg to be positioned in a selectable location within the vehicle's footwell. The length of the support leg can then be adjusted so that the foot of the support leg rests properly on the vehicle floor.

[0030] The minor support module may include one or more padded portions, protective straps and / or any other features known in the art or described in International (PCT) Patent Application No. PCT / GB2021 / 051393.

[0031] A child car seat system can be configured such that a child carrier module is detachably docked within a docking module. This allows the child carrier module to be separated from the docking module and used to transport a child out of the vehicle. The detachable docking of the child carrier module with the docking module means that the child carrier module can be selectively placed and / or secured to the docking module such that relative movement between the docking module and the child carrier module (when docked) is at least partially prevented, prohibited, reduced, or suppressed.

[0032] The system may also include a docking locking mechanism configured to selectively prevent the child carrier module from detaching from the docking module. This allows the user to securely dock the child carrier module within the docking module, ensuring that the module will not detach while driving and at other times. This arrangement enhances system safety. The docking locking mechanism may be configured to prevent the child carrier module from detaching from the docking module when the housing portion is fixed in a first or second rotational position. Thus, when positioned in the first and / or second rotational positions, the child carrier module may not detach. The child car seat system may further include a release actuator configured to operate to release the docking locking mechanism. The system may also include an emergency release device configured to allow the child carrier module to detach when positioned in any orientation, allowing for the removal of the child from the vehicle in an emergency. In use, the first and second rotational positions may relate to forward-facing and rearward-facing positions. Accordingly, when the child car seat system is configured for arrangements typically used during vehicle travel, the docking locking mechanism can provide an additional layer of safety between the child carrier module and the docking module. The child carrier module can only be separated from the docking module when it is rotated to a central rotation position (e.g., a side position facing the direction of travel). The docking locking mechanism provides additional strength and safety, which is especially important in vehicle collisions or other such scenarios.

[0033] The docking locking mechanism can be configured to release automatically when the housing portion is positioned between a first rotational position and a second rotational position. This allows the user to easily unlock the docking locking mechanism by rotating the child carrier module from the locked position, a situation typically occurring when a parent removes a minor from the vehicle. Alternatively, the docking locking mechanism can include a release actuator that the user can actuate to release the docking locking mechanism.

[0034] The child car seat system may further include an auxiliary safety lock configured to detachably secure the child carrier module to the housing portion when the child carrier module is configured in an upright position. The auxiliary safety lock is operable in all rotational positions of the housing portion relative to the base portion. When the vehicle is in motion, the child carrier module will typically be positioned in an upright position. Accordingly, the auxiliary safety lock provides additional attachment and securing between the child carrier module and the docking module, which is particularly important when the vehicle is in motion.

[0035] The child carrier module may include a seat portion attached to the backrest. The child carrier module may also include a removable bracket handle configured to be secured to the seat portion and / or backrest. When the child carrier module is not docked in a docking module, the bracket handle can be used to carry the child carrier module and the minor secured therein. When the child carrier module is docked, such as when the system is used as a car seat for a relatively large minor, the handle can be selectively removed. The bracket handle may be configured to be secured to the seat portion and / or backrest at multiple angles relative to the seat portion. The bracket handle may include an actuator, such as a button or a pair of buttons adjacent to the hinge point of the bracket handle, which the user can activate to release and reset the bracket handle. A total of two, three, four, or any other number of positions may be provided. The bracket handle is removable via a clamp and a release lever. The clamp can slide from a fixed position to a released position, where the release lever can open, for example, through 90°, to release the bracket handle. The bracket handle can then be removed from the child carrier module. The bracket handle may include components, such as molded seatbelt guides, for guiding and securing automotive seatbelts or lap belts. These components may allow the minor carrier module to be secured within the vehicle via an integral seatbelt without or except for docking modules or ISOFIX connectors.

[0036] The child-carrying module includes a seat portion attached to the backrest. The system may further include a headrest attached to the backrest and detachably attached to the docking module.

[0037] In this way, as the minor grows, the headrest can move upward along the backrest, away from the seat and connected to the docking module, thus providing a larger seating area for the minor while also providing safe and reliable support for the headrest.

[0038] The headrest can be attached to the backrest of the child support module. Alternatively, the headrest can be attached to the docking module. This allows the headrest to be positioned to provide optimal comfort and / or safety for the minor. Furthermore, as the minor grows, the headrest may move further away from the seat. The headrest may include a padded portion. This provides a more comfortable and secure headrest.

[0039] The headrest is slidably attached to the backrest. The docking module may include a headrest groove. When the child support module is docked in the docking module, the headrest can slide from the backrest into the headrest groove. The headrest may include protrusions configured to engage with the headrest groove. This allows the headrest to be positioned comfortably and safely for the minor, depending on the minor's size. Furthermore, the headrest may move as the minor grows. The headrest can be adjusted between multiple positions. This allows the headrest height to be adjusted according to the minor's size. Preferably, the headrest is adjustable between at least three positions. The headrest can be locked in at least three positions. The headrest can slide between at least three positions. The headrest can always remain attached to the child support module. This may provide a more convenient system when all arrangements provide only a single headrest. Furthermore, it can prevent the risk of permanent or accidental misuse, thus providing a safer system.

[0040] The rotary stop can be recoverable. Accordingly, the rotary stop can recoil or spring back to its original shape after the compressive force is removed. The rotary stop can impart or apply force to an object or component that applies compressive force to counteract or at least partially resist the compressive force. In this way, the rotary stop can at least partially repel the compressive force acting on it, thereby reducing the maximum or total peak force.

[0041] Alternatively, the spin stop can be configured to fold, shear, or otherwise resist rotation of the child carrier module relative to the docking module, thereby reducing maximum or peak forces, rather than returning to its original shape like an elastic member. Spin stops configured to fold, shear, or otherwise resist rotation in this manner are useful in vehicle collision scenarios. Typically, child car seats are replaced after a vehicle collision. In this respect, damage to the spin stop may not be a significant consideration. The spin stop is replaceable so that it can be replaced if damaged in a vehicle collision scenario.

[0042] A rotation stop may include: a fixed portion; a first movable portion configured to be movable relative to the fixed portion between a first position and a second position, wherein the movable portion is spaced a first distance from the fixed portion at the first position and a second distance, the second distance being less than the first distance, between the movable portion and the fixed portion at the second position; and a first reversible member located between the fixed portion and the first movable portion. The first reversible member may be configured to cause the first movable portion to move away from the second position and toward the first position. Thus, the rotation stop is compressible, meaning the first movable portion can move to a position closer to the fixed portion. Rotation of the child carrier module in a first direction causes the first movable portion to move from the first position to the second position, counteracting the action relative to the first reversible member. In this way, the rotation stop allows a certain degree of rotation in the first direction, and the first reversible member resists rotation. The action of the first reversible member can reduce the peak force experienced by a child located in the child carrier module in a turning or vehicle collision scenario. The movement of the first movable portion from the second position away from the first position can be prevented by the fixed portion or other means. Therefore, once the first movable portion is moved to the second position, further rotation in the first direction can be prevented.

[0043] A first movable portion may be positioned relative to a fixed portion at a first intermediate position between a first position and a second position. A first reversible member may be configured such that a greater force than is required to move the first movable portion from the first position to the first intermediate position is needed to move the first movable portion from the first position to the first intermediate position. The first reversible member may include a first sub-member and a second sub-member. The first sub-member may be configured to resist movement of the first movable portion from the first position to the first intermediate position, and the second sub-member may be configured to resist movement of the first movable portion from the first intermediate position to the second position. The second sub-member has a larger degree of force or requires a greater force to compress compared to the first sub-member. Alternatively, the first sub-member may be configured to resist movement of the first movable portion from the first position to the first intermediate position, and both the first and second sub-members may be configured to resist movement of the first movable portion from the first intermediate position to the second position. Thus, the first and second sub-members may be combined to resist movement of the first movable portion from the first intermediate position to the second position.

[0044] Therefore, the rotation stop can be configured to provide desired cornering comfort characteristics by moving the first movable portion between a first position and a first intermediate position, and to provide desired vehicle side impact characteristics by moving the first movable portion between a first intermediate position and a second position.

[0045] The rotary stop may further include: a second movable portion configured to be movable relative to a fixed portion between a third position and a fourth position, wherein the movable portion is spaced a third distance from the fixed portion in the third position, and a fourth distance, less than the third distance, is spaced from the fixed portion in the fourth position; and a second reversible member located between the fixed portion and the second movable portion. The second reversible member may be configured to cause the second movable portion to move away from the fourth position and toward the third position. The direction of movement of the first movable portion from the first position to the second position may be opposite to the direction of movement of the second movable portion from the third position to the fourth position. Therefore, the compressibility of the rotary stop means that the second movable portion can move to a position closer to the fixed portion. Rotation of the child-carrying module in a second direction, opposite to the first direction discussed above with reference to the first movable portion, may cause the second movable portion to move from the third position to the fourth position, counteracting the action of the second reversible member. Thus, the rotary stop may allow a certain degree of rotation in the second direction, and the second reversible member may resist rotation. The action of the second reversible member may reduce the peak force experienced by a child located in the child-carrying module in a turning or vehicle collision scenario. The movement of the second movable part away from the third position from the fourth position can be prevented by fixing the part or by other means. Therefore, once the second movable part is moved to the fourth position, further rotation in the second direction can be prevented.

[0046] The first and second recoverable components can be portions of a single spring, elastic member, or other known elastic member. In one example, a spring may be located between the first and second movable portions, passing through or along the fixed portion, thereby providing the first and second recoverable components.

[0047] The second movable portion can be positioned relative to the fixed portion at a second intermediate position between the third and fourth positions. The second reversible member can be configured such that a greater force than is required to move the second movable portion from the third position to the second intermediate position is needed to move the second movable portion from the third position to the second intermediate position. The second reversible member may include a third sub-member and a fourth sub-member. The third sub-member can be configured to resist movement of the second movable portion from the third position to the second intermediate position, and the fourth sub-member can be configured to resist movement of the second movable portion from the second intermediate position to the fourth position. Compared to the third sub-member, the fourth sub-member may have a larger degree of compression or require a greater force to compress. Alternatively, the third sub-member can be configured to resist movement of the second movable portion from the third position to the second intermediate position, and both the third and fourth sub-members can be configured to resist movement of the second movable portion from the second intermediate position to the fourth position. Thus, the third and fourth sub-members can be combined to resist movement of the second movable portion from the second intermediate position to the fourth position.

[0048] Therefore, the rotation stop can be configured to provide desired cornering comfort characteristics by moving the first movable portion between a first position and a first intermediate position, and to provide desired vehicle side impact characteristics by moving the first movable portion between a first intermediate position and a second position.

[0049] The rotation stop can be configured to be movable between an engaged position and a disengaged position. In the engaged position, the rotation stop is configured to restrict rotation of the minor carrier module relative to the docking module about a rotation axis, while in the disengaged position, rotation of the minor carrier module relative to the docking module about a rotation axis is unrestricted. Accordingly, the rotation stop can retract or otherwise move from the engaged position to the disengaged position to allow the minor carrier module to rotate freely relative to the docking module. Positioning the rotation stop in the disengaged position allows a user, such as a parent, to redirect the minor carrier module, for example, from a forward-facing position to a rearward-facing position, or to a side-facing position.

[0050] In one example, the rotary stop may be positioned on the docking module and configured to engage with the minor carrier module in the engagement position. The rotary stop may be removed from the minor carrier module and moved into a disengaged position, wherein the rotary stop may be spaced apart from the minor carrier module.

[0051] In another example, the rotary stop may be located on the minor carrier module and may be configured to engage with the docking module in an engaged position. The rotary stop may be removed from the docking module and moved into a disengaged position, wherein the rotary stop may be spaced apart from the docking module.

[0052] In another example, the docking module can be multi-part. A first part can be configured to rotatably relative to a second part. A minor carrier module is attached to or can be attached to either the first or second part. The other of the first and second parts can be attached to a vehicle seat. A rotation stop can be positioned on either the first or second part of the docking module and can be configured to engage with the other of the first and second parts in an engaged position. The rotation stop can move from the other of the first and second parts to a disengaged position, wherein the rotation stop can be spaced apart from the other of the first and second parts.

[0053] The rotary stop can be configured to be driven from a disengaged position to an engaged position. The child car seat system may further include an actuator that moves the rotary stop from the engaged position to the disengaged position. The rotary stop may include a resettable member, such as a spring, an elastic member, or any other known resettable member. The resettable member may be configured to cause the rotary stop into the engaged position. The actuator may be actuated against the action of the resettable member. Therefore, the rotary stop can be positioned in the disengaged position only when the actuator is actuated. Thus, the rotary stop can generally be positioned in the engaged position. This prevents the user from leaving the rotary stop in the disengaged position. When a minor is placed in the child carrier module, the actuator may be placed in a location away from or out of the minor's reach. For example, the actuator may be placed at the rear or below the child carrier module, or on the docking module. This prevents the minor placed in the child carrier module from actuating the actuator.

[0054] A child car seat system may include multiple rotary stops. These rotary stops are rotatably distributed about a rotation axis. Alternatively or additionally, the multiple rotary stops may be arranged at different lateral distances from the rotation axis. Each of the multiple rotary stops may be the same as or different from the others, for example, by having different spring characteristics. In one example, the child car seat system may include two identical rotary stops spaced laterally from the rotation axis and rotating 180° apart about the rotation axis. In this embodiment, one rotary stop may be arranged in the forward portion of the docking module, and the other rotary stop may be arranged in the rearward portion of the docking module. Alternatively, one rotary stop may be arranged in the left side portion of the docking module, and the other rotary stop may be arranged in the right side portion of the docking module.

[0055] As discussed in this article, rotary stops can be laterally spaced from the rotary shaft. The distance between the rotary shaft and the rotary stop can be considered when selecting the ideal characteristics of the rotary stop. For example, the desired or required spring rating and travel distance may depend on the distance between the rotary shaft and the rotary stop. A relatively large distance between the rotary shaft and the rotary stop means that a relatively weak spring with a relatively large travel can be expected or required. A relatively small distance between the rotary shaft and the rotary stop means that a relatively strong spring with a relatively small travel may be expected or required. Attached Figure Description

[0063] The following description provides exemplary embodiments, and is consistent with the accompanying drawings. Figure 1 The present invention is intended to explain the principles of this disclosure. However, the scope of the invention is not limited to the precise details of the embodiments, as variations will be apparent to those skilled in the art and are considered to be covered by the description. The terminology used herein should be given a broad interpretation, including equivalent functions and features. In some cases, alternative terms for structural features may be provided, but these terms are not intended to be exhaustive.

[0064] Descriptive terms should also be interpreted as broadly as possible; for example, the term "comprising" as used in this specification means "consisting of at least part of...", so that features other than those beginning with or including that term may also appear when interpreting each statement in this specification that includes the term "comprising". Related terms, such as "comprising" and "including", should be interpreted in the same manner. Directional terms, such as "vertical", "horizontal", "upward", "downward", "top", "bottom", "upper", and "lower", are generally used for ease of interpretation with reference to illustrations and are not intended to ultimately limit them if an equivalent function can be achieved with another size, orientation, and / or direction.

[0065] The description herein refers to embodiments with specific combinations of features; however, it is envisioned that further combinations and cross-combinations of compatible features between embodiments would be possible. In fact, isolated features can function as an invention independently of other features and do not necessarily need to be implemented as a complete combination.

[0066] The general descriptive term "child car seat" in relation to the technical field of this disclosure is not intended to be limiting. In the art, there are broad terms applicable to this disclosure and they may be used interchangeably to describe the device without affecting its scope and interpretation. For example, "child car seat" can be a term encompassing all safety devices used by infants, toddlers, or children for sitting and / or lying in a flat position, such as booster seats or carriers, respectively.

[0067] Figure 1 This is a perspective view of a child car seat system 100 having a child support module 200 and a docking module 300. A minor can be placed in the child support module 200. The child support module 200 includes a seat portion 210 and a backrest portion 220 rotatably or pivotally attached thereto. Relative rotation of the seat portion 210 and the backrest portion 220 can be achieved by a locking hinge discussed herein. A release actuator (not shown) can be provided, and actuation of the release actuator unlocks the hinge connecting the seat portion 210 and the backrest portion 220, allowing adjustment of the relative tilt between the seat portion 210 and the backrest portion 220. The release actuator may be incorporated into a seatbelt guide, located at the rear of the child support module 200, or in any other preferred location.

[0068] The child support module 200 also includes a headrest 230 and a bracket handle 240. A minor can be placed in the child support module 200, with their buttocks and legs supported by the seat portion 210, their back and arms supported by the backrest portion 220, and their head supported by the headrest 230. The headrest 230 is adjustable and can slide between at least a first lower headrest position, a second middle headrest position, and a third upper headrest position. The position of the headrest 230 can be adjusted as the child grows. The headrest 230 can be locked in place to prevent accidental height adjustment.

[0069] For comfort, a padded portion covering the seat portion 210, backrest portion 220, and headrest 230 can be provided. An integrated carrying strap can also be provided to secure the minor to the minor carrier module 200. This carrying strap can be stored within the minor carrier module 200 when not in use. The minor carrier module 200 and the minor placed within it can be carried via a bracket handle 240. The bracket handle 240 can be rotatably adjustable relative to the seat portion 210 and / or backrest portion 220.

[0070] The minor support module 200 can be detachably connected to the docking module 300, as detailed below. Figure 2 .

[0071] The docking module 300 includes a housing portion 305, a minor support module 200 that can be docked to the housing portion 305, and a base portion 310 that supports the housing portion 305. The housing portion 305 includes docking guides and / or mechanisms to ensure that the minor support module 200 is correctly positioned and aligned and securely attached to the docking module 300.

[0072] The housing portion 305 and the minor support module 200 attached to the housing portion 305 can surround relative to the base portion 310. Figure 1 The axis rotates approximately vertically in the view shown.

[0073] The base portion 310 includes an ISOFIX latch 320 to allow the base portion 310 to be securely connected to the vehicle. An ISOFIX mounting lever 330 is provided, which slides out when pressed. In some examples, the lever 330 may be replaced by a button. An ISOFIX slider 340 is provided to decouple the ISOFIX connector 320. During installation, the ISOFIX slider 340 indicates that the ISOFIX latch 320 is correctly installed and can be slid to decouple the ISOFIX latch 320.

[0074] The docking module 300 also includes a support leg 350 (partially shown) configured to extend from the base portion 310 to the vehicle floor. The support leg 350 is rotatably attached to the base portion 310 such that the support leg can... Figure 1 The extended position and the storage position shown (where the support leg 350 is located near the lower surface of the base portion 310) are movable. Because the support leg 350 can be retracted to a position near the base portion 310 as the child grows, this allows the docking module 300 to be reconfigured to accommodate larger or older children.

[0075] Figure 2 yes Figure 1 The diagram shows a perspective view of a child car seat system 100, in which a child support module 200 is nested in a housing portion 305 of a docking module 300, and the child support module 200 and housing portion 305 are detached from a base portion 310.

[0076] By lowering the child support module 200 into the housing portion 305, the child support module 200 can dock within the housing portion 305. A locking mechanism then allows the child support module 200 to be detachably attached to the housing portion 305. Attachment can be automatic or driven by a user (e.g., a parent). The base portion 310 includes a bracket 360. The bracket 360 shown includes two bent plate members that engage with the housing portion 305 at multiple locations on the rear side of the housing portion 305. The bracket 360 also includes a plate portion 361 with a substantially flat bottom. The bending of the bracket members substantially matches the bending of the rear portion of the housing portion 305. In use, the housing portion 305 is configured to be securely attached to the bracket 360.

[0077] The bracket 360, housing portion 305, and child support module 200 (when attached to housing portion 305) are rotatable relative to the remainder of base portion 310. The rotation of the child support module 200 relative to the base portion 310 of docking module 300 is described below. Figure 6 A more detailed discussion was held.

[0078] Figure 3 yes Figure 2 An enlarged view of the docking module 300 shown. The bracket 360 can rotate relative to the base portion 310 via the hub 370. The bracket 360, the housing portion (not shown), and the minor support module (not shown) attached thereto can be rotated around... Figure 3 The view shown depicts a substantially vertical axis of rotation, with the axis passing through the center of hub 370. The rotation of the minor support module relative to base portion 310 is shown below. Figure 6 A more detailed discussion was held.

[0079] The base portion 310 also includes a swivel stop 380 that is laterally offset from the hub 370. (See reference...) Figure 5 As discussed in detail, the rotation stop 380 can retract into and out of the base portion 310 to selectively engage with the bracket 360 and restrict the rotation of the minor carrier module attached to the bracket 360 relative to the base portion 310 of the docking module 300.

[0080] The bracket 360 includes holes 390 and 391 in the planar plate portion 361. The first hole 390 is positioned towards the rear of the bracket 360, and the second hole 391 is positioned towards the front of the bracket 360. A rotation stop 380 is positioned towards the rear of the base portion 310. When the bracket 360 and the child support module are arranged in a forward-facing position, the rotation stop 380 can be located within the first hole 390 to restrict rotation from the forward-facing position, and the rotation stop 380 engages with the planar plate portion 361. When the bracket 360 and the child support module are arranged in a rearward-facing position, the rotation stop 380 can be located within the second hole 391 to restrict rotation from the rearward-facing position, and the rotation stop 380 engages with the planar plate portion 361.

[0081] Figure 4 This is a front view of the rotation stop 380 of the docking module. The rotation stop 380 is configured to selectively restrict rotation of the bracket relative to the base portion. The rotation stop 380 is positioned in an extended position and a retracted position, as shown below. Figure 5 The discussion that took place.

[0082] With the bracket and the minor support module facing forward, the rotation stop 380 can be arranged within the first hole 390 of the flat plate portion 361 of the bracket. The rotation stop 380 is arranged relative to the holes 390 and 391, such that the rotation stop 380 is tightly fitted within the holes 390 and 391. Therefore, when the rotation stop 380 is arranged within the holes 390 and 391, a relatively small rotation of the bracket and the minor support module causes the rotation stop 380 to engage with the flat plate portion 361 of the bracket.

[0083] like Figure 4 As shown, the rotation stop 380 extends within the first hole 390 so that the bracket and the minor support module are arranged in a forward-facing direction. Therefore, any rotation of the bracket and the minor support module starting in the forward-facing direction will cause the rotation stop 380 to engage with the flat plate portion 361 of the bracket.

[0084] The rotary stop 380 includes a fixed portion 381, which is fixed relative to the remainder of the base portion to prevent lateral movement. Figure 4(The x and y directions shown). The only possible movement of the fixed part 381 relative to the remainder of the base part is to retract the rotation stop 380 back into the base part. Figure 4 (in the z-direction shown), see below for reference. Figure 5 The only possible motion is described.

[0085] The rotary stop 380 also includes a first movable portion 382 that is movable relative to the fixed portion 381. The first movable portion 382 is in a first position (e.g. Figure 4 The first movable portion 382 (shown in the diagram) and the second position (not shown) are movable relative to the fixed portion 381. At the first position, a first distance separates the first movable portion 382 from the fixed portion 381. At the second position, a second distance separates the first movable portion 382 from the fixed portion 381, and the second distance is less than the first distance. The first movable portion 382 can move along... Figure 4 The x-direction shown is translated relative to the fixed part 381.

[0086] A first spring 383 is located between the fixed portion 381 and the first movable portion 382. Other restorable components, such as elastic members, are conceivable. The first spring 383 is configured to cause the first movable portion 382 away from the second position (not shown) and away from the fixed portion 381 toward the first position (e.g., ...). Figure 4 (As shown).

[0087] When the rotary stopper 380 is located within the first hole 390, the minor support module is in a clockwise direction relative to the docking module (e.g., ...). Figure 4 (See view shown) Rotation of the forward-facing arrangement away from the minor support module will cause the first movable part 382 to engage with the flat plate portion 361 of the bracket. The action of the first spring 383 will pull the first movable part 382 away from... Figure 4 The indicated position moves toward the fixed part 381, thereby compressing the first spring 383. Therefore, the first spring 383 will exert a force to counteract the rotation of the minor-bearing module.

[0088] Therefore, the rotation of the minor-carrying module caused by cornering forces or side impact forces will be counteracted by the first spring 383 to provide a more comfortable ride or reduce peak impact forces. Thus, the comfort and / or safety of the minor is improved.

[0089] The rotary stop 380 also includes a second movable portion 384 that is movable relative to the fixed portion 381. The second movable portion 384 is in a third position (e.g., Figure 4The second movable portion 384 is movable relative to the fixed portion 381 between the third position (shown) and the fourth position (not shown). At the third position, a third distance separates the second movable portion 384 from the fixed portion 381. At the fourth position, a fourth distance separates the second movable portion 384 from the fixed portion 381, and the fourth distance is less than the third distance. The second movable portion 384 can move along... Figure 4 The x-direction shown is translated relative to the fixed part 381.

[0090] The movement of the second movable part 384 from the third position to the fourth position can be in the opposite direction to the movement of the first movable part 382 from the first position to the second position. The first distance can be equal to or different from the third distance. The second distance can be equal to or different from the fourth distance.

[0091] The second spring 385 is located between the fixed portion 381 and the second movable portion 384. Other restorable components, such as elastic elements, are conceivable. The second spring 385 may have the same or different spring constant as the first spring 383. The first spring 383 and the second spring 385 may have equal or different maximum travel distances. Preferably, the first spring 383 and the second spring 385 are identical. The second spring 385 is configured to cause the second movable portion 384 to move away from a fourth position (not shown) and away from the fixed portion 381 toward a third position (e.g., ...). Figure 4 (As shown).

[0092] Although the system 100 described herein has two springs 383 and 385, in one example, a single spring may be provided and located between the first movable portion 382 and the second movable portion 384, the single spring passing through or along the fixed portion 381. Thus, the first spring 383 and the second spring 385 may be part of a single, longer spring.

[0093] When the rotary stopper 380 is located within the first hole 390, the minor support module is in a counterclockwise direction relative to the docking module (e.g., ...). Figure 4 (See view shown) Rotation of the front-facing portion away from the minor support module will engage the second movable portion 384 with the flat plate portion 361 of the bracket. The action of the second spring 385 will disengage the second movable portion 384 from... Figure 4 The indicated position moves toward the fixed part 381, thereby compressing the second spring 385. Therefore, the second spring 385 will exert a force to counteract the rotation of the minor-bearing module.

[0094] Therefore, the rotation of the minor-carrying module caused by cornering forces or side impact forces will be offset by the second spring 385 to provide a more comfortable ride or reduce peak impact forces. Thus, the comfort and / or safety of the minor is improved.

[0095] like Figure 4 As shown, the first movable portion 382 and the second movable portion 384 are retractably coupled, but can be provided in any mutual or non-mutual arrangement. Furthermore, a single shared fixed portion 381 is shown; however, it is alternatively possible to provide two fixed portions, one each for fixed portions 382 and 384.

[0096] Figure 5 yes Figure 4 Side view of the rotary stop 380 shown. Figure 5 The rotary stop 380 is provided relative to Figure 4 Another view shown.

[0097] exist Figure 5 In the diagram, the rotary stop 380 is shown in the extended or deployed position. Therefore, the rotary stop 380 is located within the bore and engages with the planar plate portion, as shown in the reference. Figure 4 As discussed. Therefore, any rotation of the bracket and the minor support module will cause the rotation stop 380 to engage with the flat plate portion of the bracket.

[0098] The fixing portion 381 is shown extending below the first spring 383 and the second spring 385, and is laterally fixed relative to the remainder of the base portion so that lateral movement is impossible. Figure 5 (in the x and y directions shown). The only possible movement of the fixed part 381 relative to the remainder of the base part is to retract the rotation stop 381 back into the base part. Figure 5 (in the z-direction shown).

[0099] An unused space 386 is provided below the fixed portion 381. This is for moving the rotary stop 380 from the engaged position (e.g., ...). Figure 5 Move the fixed part 381 downwards (as shown) to the separation position (not shown). Figure 5 (As shown) into the space 386 below the fixed part 381. When the first movable part 382 and the second movable part 384 are attached to the fixed part 381, the first movable part 382 and the second movable part 384 are pulled out from the hole. Accordingly, the minor support module can rotate freely.

[0100] A lower spring 387 is provided together with the space 386 below the fixed portion 381. The lower spring 387 is configured and oriented to oppose the downward movement of the fixed portion 381 into the space 386 below the fixed portion 381. Therefore, the lower spring 387 can cause the fixed portion 381, together with the first movable portion 382 and the second movable portion 384 and the springs attached to the first spring 383 and the second spring 385, to move away from the space 386 and into an engaged position (e.g., Figure 5 (As shown). An actuator may be provided and is operable to move the fixed portion 381 downward into the space 386 against the action of the lower spring 387 to move the rotary stop 380 from the engaged position to the disengaged position. When the actuator is no longer driven, the lower spring 387 may cause the rotary stop 380 to move from the disengaged position to the engaged position.

[0101] Figure 6 for Figure 1 The diagram shows a side view of a child car seat system 100. The housing portion 305 is shown in a rearward-facing orientation, but it can be arranged in any orientation, such as forward or sideways. When the child carrier module is docked within the housing portion 305, the orientation of the child carrier module (not shown) will match the orientation of the housing portion 305. The housing portion 305 can be locked in either a rearward-facing or forward-facing orientation, as is typically used when in motion. A rotary release actuator 395 is provided as a button on the docking module 300, although other actuators, such as levers or sliders, are contemplated.

[0102] The housing portion 305 is shown attached to the planar plate portion 361 of the base portion 310 of the docking module 300. The planar plate portion 361 is rotatably attached to the remainder of the base portion 310 of the docking module 300 via a pivot pin 400. Although the pin 400 is shown, any suitable connecting mechanism, component, or device that allows rotation can be used. Accordingly, the housing portion 305 and the minor carrier module docked therein are rotatable relative to the base portion 310 of the docking module 300 about a rotation axis 410.

[0103] The rotation stop 380 is movable between an engaged position and a disengaged position along the rotation stop shaft 420. The rotation stop shaft 420 is laterally spaced by a distance d from the rotation shaft 410. Therefore, when the rotation stop shaft 380 is in the engaged position, the rotation of the housing portion 305 about the rotation shaft 410 results in a substantially linear force applied to the rotation stop 380. The force applied to the rotation stop can move the first movable portion 382 or the second movable portion 384 toward the fixed portion 381 to correspondingly counteract the action of the first spring 383 or the second spring 385, thereby compressing the springs 383 and 385. In this way, the rotation of the housing portion 305 and the minor support module mated therein about the rotation shaft 410 can be resisted. The maximum possible rotation of the housing portion 305 about the rotation shaft 410 is set based on the travel distance of the springs 383 and 385. Once the springs 383 and 385 are fully compressed, the housing portion 305 can no longer rotate about the rotation shaft 410 in the same direction.

[0104] Although not shown in the figures, the first spring 383 and the second spring 385 may have two strengths and / or levels, or in each example, a second, shorter spring may be provided to provide a first resistance for cornering comfort and a second resistance for vehicle crash performance, as discussed herein. Furthermore, although the rotary stop 380 is described herein as having two springs 383, 385, in one example, a single spring may be provided and located between the first movable portion 382 and the second movable portion 384, passing through or along the fixed portion 381. Thus, the first spring 383 and the second spring 385 may be part of a single, longer spring.
