DETAILED DESCRIPTION OF THE INVENTION

[0042] A detailed description of one or more embodiments of the disclosed apparatus and method is illustrated herein by way of example and not by way of limitation with reference to the figures.

[0043] Referring to Figure 1, a schematic diagram of a vehicle 100 and a child restraint system 102 that may incorporate embodiments of the present disclosure is shown. As shown in Figure 1, the vehicle 100 (e.g., a personal vehicle, a ride-hail or ride-share vehicle, etc.) includes a vehicle seat 104 in which a child restraint system 102 is installed. The child restraint system 102 includes an infant car seat 106 secured to the vehicle seat 104 of the vehicle 100 via an anchor system 108 (shown diagrammatically). The vehicle seat 104 has a vehicle seat back 110, a vehicle seat pan 112, and a seat bight (i.e., the area of ​​intersection of the vehicle seat back 110 and the vehicle seat pan 112). The anchor system 108 is configured to secure the infant car seat 106 to the vehicle seat 104. The anchor system 108 may help ensure that the infant car seat 106 is installed in a tight fit with the vehicle seat 104, thereby ensuring that the infant car seat system 106 is safely and securely attached and installed within the vehicle 100 when installed.

[0044] 1, the infant car seat 106 is secured to the vehicle seat 104 in a rear-facing orientation, with the front portion 114 of the infant car seat 106 facing the vehicle seat back 110 and the rear portion 116 of the infant car seat 106 positioned away from the vehicle seat back 110. Thus, when a child sits in the infant car seat 106, the child's feet are at the front portion 114 of the infant car seat 106 and the child's head is at the rear portion 116 of the infant car seat 106. Thus, the infant car seat 106 is a rear-facing infant car seat.

[0045] Although illustrated using a specific child car seat configuration, embodiments of the present disclosure may be applicable to a variety of different vehicle child car seats. For example, a child car seat of the present disclosure may be a convertible child car seat, an infant car seat, etc. As used herein, the term "convertible child car seat" refers to a seat that can be used in both rear-facing and forward-facing orientations and is suitable for use by children weighing 5 to 65 pounds and / or up to 49 inches tall. A convertible child car seat may also be referred to herein as an upright child car seat or a toddler car seat. As used herein, the term "infant car seat" refers to a seat as defined by those skilled in the art. For example, an infant car seat may be described as a seat used by infants or children who are too small to use a convertible child car seat and may include a carrying handle to allow the infant car seat to be transported outside of a vehicle.

[0046] When loading or unloading a child into or from a vehicle, a caregiver (e.g., a provider, parent, guardian, etc., generally referred to as a "caregiver") may find it difficult to load or unload a child into or from a child restraint system while the child seat is installed in the vehicle. This may be particularly true in rear-facing configurations. For example, it may be difficult for the caregiver to bend down and reach into the vehicle to position the child in the seat and buckle the seat belt. The space between the sides of the child restraint system and the roof / doors of the vehicle may create limited maneuvering space for the caregiver. The same obstacles arise when removing a child from a car seat while it is installed in the vehicle. For infants and toddlers, lift-out seats are common to address this issue. However, as a child grows, their weight increases, making it increasingly difficult to lift the seat out of the vehicle. Due to this difficulty, the caregiver may tend to leave the lift-out seat portion of the vehicle, thus requiring them to bend down and reach into the vehicle to properly secure the child. With this in mind, embodiments of the present disclosure aim to bring a child closer to the caregiver, thus limiting the bending and reaching required to get a child in and out of a car seat.

[0047] 2A-2C, an example of a child restraint system 200 is illustrated in accordance with one embodiment. The child restraint system 200 may be removably secured or supported to a vehicle seat 202, for example, via a latch or anchoring mechanism 204. This latch or anchoring system is sometimes referred to as a "Lower Anchors and Tethers for Children" (e.g., a LATCH system). Alternatively, or in addition, the child restraint system 200 may be removably secured to the vehicle seat 202 via a vehicle belt associated with the vehicle seat 202.

[0048] As shown, child restraint system 200 includes a child car seat 206 and a support base 208. In this exemplary configuration, support base 208 includes a positioning assembly 210 configured to allow adjustment or change of the position and / or orientation of child car seat 206 relative to support base 208 and / or vehicle seat 202. Support base 208 includes an anchoring mechanism 204 at an end thereof having a securing mechanism 212, such as a releasable hook or latch. Figure 2A illustrates child car seat 206 separated from support base 208, Figure 2B illustrates child car seat 206 installed on support base 208 in a first orientation (e.g., rear-facing), and Figure 2C illustrates child car seat 206 rotated to a second orientation (e.g., forward-facing) by positioning assembly 210.

[0049] In this exemplary embodiment, the positioning assembly 210 includes a positioning element 214 for connecting with the child car seat 206, which is movable relative to the structure of the support base 208. As shown in FIG. 2A , the child car seat 206 may be separable from the positioning element 214 of the support base 208. Such separability may be provided by a releasable pin, snap, clip, slot engagement, or the like. In other embodiments, the child car seat 206 and the positioning element 214 and / or the support base 208 may be assembled as a non-separable structure such that the child car seat 206 cannot be removed from the support base 208. However, in embodiments with a removable child car seat 206, the child car seat 206 may be configured to be removable from installation in a vehicle to installation on a stroller, or to be used independently of other structures or assemblies. In some embodiments, the child seat 206 may be inseparably coupled, e.g., if not detachable from the support base 208, but may be reclined or otherwise movable relative to the support base 208 (but not detachable).

[0050] As shown in FIG. 2A , the positioning element 214 of the positioning assembly 210 may include a recline structure 216 configured to allow adjustment of the recline of the child seat 206 relative to the support base 208. In FIG. 2A , the child restraint system 200 is shown partially installed in a vehicle seat 202. The vehicle seat 202 includes a vehicle seat back 218 and a vehicle seat pan 220. The support base 208 rests on the vehicle seat pan 220 of the vehicle seat 202 and is configured to support the child seat 206 thereon. In this exemplary configuration, the child restraint system 200 includes a rebound bar 222 extending from a portion of the support base 208 that rests on the vehicle seat pan 220, with the rebound bar 222 extending upward therefrom and resting on the vehicle seat back 218. The rebound bar 222 may provide stability to the child restraint system 200 in the event of a crash, etc.

[0051] In the illustrated non-limiting embodiment, a stabilization leg 224 having a fixed or adjustable length is connected to a portion of the support base 208. As shown, the stabilization leg 224 is located at the end of the support base 208 opposite the rebound bar 222. The stabilization leg 224 may be rotatable or foldable relative to the support base 208 between an extended configuration (shown in a partially extended state), in which the stabilization leg 224 may be configured to abut the vehicle floor and provide support to the child restraint system 200, and a stowed configuration, in which the stabilization leg 224 is stored below or within (e.g., below or within) the cavity of the child restraint system 200. In some configurations, the stabilization leg 224 may protrude slightly from the bottom of the support base 208 when in the stowed configuration to facilitate use of the stabilization leg 224 during installation of the child restraint system 200 in a vehicle.

[0052] According to embodiments of the present disclosure, the positioning assembly 210 may provide one or more degrees of movement and adjustment of the child seat 206 relative to the support base 208. For example, the positioning element 214 may provide a first degree of adjustment through the reclining structure 216 of the positioning element 214, which allows adjustment of the reclining orientation of the child seat 206 relative to the support base 208. A second degree of adjustment may be provided, for example, through interaction of the positioning element 214 with the support base 208 to which the positioning element 214 is coupled. For example, the positioning element 214 may be rotatably coupled to the support base 208 and rotatable about an axis 226. Thus, the child seat 206 may be rotatable relative to the support base 208 and / or the vehicle seat 202 about the axis 226. In some embodiments, the angle of rotation may be completely free to allow 360-degree rotation about the axis 226. In other embodiments, a limited angle of rotation may be set, such as 180 degrees. 2A and 2B illustrate the child car seat 206 in a rear-facing orientation (relative to the vehicle seat 202), and FIG. 2C illustrates the child car seat 206 rotated 180 degrees in a forward-facing orientation (relative to the vehicle seat 202). It will be appreciated that the child car seat 206 may be freely rotatable about the axis 226, even if the total rotation angle is limited and less than 360 degrees, so any angle between 0 degrees (FIGS. 2A and 2B) and 180 degrees (FIG. 2C) may be possible. For example, the child car seat 206 may be rotated 90 degrees so that it faces vertically in the fore-aft direction (e.g., toward the side vehicle door). Such a rotational orientation may improve ease of use and access for caregivers when placing a child in or removing a child from the child car seat 206.

[0053] In addition to providing rotation of the child car seat (e.g., between forward-facing and rear-facing positions and positions therebetween), some embodiments of the present disclosure also provide for additional rotation and / or translation of the child car seat. For example, according to some embodiments of the present disclosure, the child car seat and support structure may be configured to allow the child car seat to move toward the parent for easier access during child docking or removal. Such additional movement may include, for example, sliding, pivoting, translating, tilting, and / or a combination of movements.

[0054] According to a non-limiting embodiment, a child restraint system includes a rear-facing car seat that improves usability by allowing the child to move toward the caregiver, facilitating loading and unloading of the child. The child restraint system may include a lower stationary support base that may be securely secured to the vehicle using any available method, such as LATCH, road legs, tethers, vehicle belts, etc. The portion of the child restraint system that retains the child (e.g., a child seat) is positioned above and secured to the lower portion sufficiently to transfer all forces experienced in a vehicle collision. The child seat may include a five-point harness for retaining and restraining the child within the child seat and any adjustments necessary to accommodate the child's growth and / or adjustment between reclined and non-reclined positions.

[0055] According to some embodiments, there may be mechanisms and various intermediate portions between the child car seat (e.g., upper portion) and the support base (e.g., lower stationary portion) of the child restraint system. The child car seat may be connected to a positioning assembly that allows the child car seat to slide (e.g., forward, rearward, sideways, etc.) relative to the lower stationary portion or support base. In some embodiments, the positioning assembly may include a sliding layer and a pivoting layer. The pivoting layer may be configured to allow full rotation of the components attached to it (e.g., child car seat, other layers). The pivoting may be lateral relative to the support base, directing the foot end of the child restraint system (e.g., the end toward which the child occupant's feet point) toward the side of the vehicle. Thus, in some embodiments, adjusting the pivoting layer laterally may change the axis of movement of the sliding layer so that the axis of sliding direction is directed toward the side of the vehicle rather than the front or rear of the vehicle. Thus, sliding the child car seat moves the child toward the side of the vehicle, moving the child into a convenient position for a caregiver to place or remove the child from the child car seat.

[0056] 3A and 3B, schematic diagrams of a child restraint system 300 installed on a vehicle seat 302 are shown, according to one embodiment of the present disclosure. FIG. 3A illustrates the child restraint system 300 in a first state or position (e.g., sideways), and FIG. 3B illustrates the child restraint system 300 in a second state or position (e.g., extended sideways). The child restraint system 300 may be releasably secured to the vehicle seat 302 by an anchoring mechanism 304 and may include a child seat 306 movably mounted to a support base 308, which may be configured as described herein (e.g., as shown and illustrated above or below). The child restraint system 300 of FIGS. 3A and 3B is similar to the child restraint system shown and described with respect to FIGS. 2A-2C and includes a positioning assembly 310 disposed between the support base 308 and the child seat 306. In this configuration, the positioning assembly 310 includes a first positioning element 312 and a second positioning element 314 .

[0057] The first positioning element 312 of the positioning assembly 310 of FIGS. 3A and 3B may be similar in part to the positioning element 214 shown in FIGS. 2A-2C. That is, the first positioning element 312 of the positioning assembly 310 may be a rotatable base or structure that is rotatably mounted or configured relative to the support base 308. Accordingly, the first positioning element 312 may be referred to as a swivel or rotating base. The first positioning element 312 may provide a first degree of freedom in the form of rotation about an axis 316 (e.g., an axis similar to axis 226 through the child restraint system 300). A second degree of freedom may be provided through the second positioning element 314 of the positioning assembly 310. The second positioning element 314 is configured to provide translational or sliding movement of the child seat 306 relative to the first positioning element 312 and the support base 308. For example, as shown in FIG. 3B, child seat 306 and second positioning element 314 are translated into position relative to first positioning element 312 and the remainder of support base 308.

[0058] 3A and 3B , the first positioning element 312 of the positioning assembly 310 can provide rotation about an axis 316 to change the orientation of the child car seat 306 relative to the support base 308 (and the vehicle seat 302 when installed in a vehicle). In some configurations, the rotation angle provided by the first positioning element 312 can be limited to 90 degrees. Such rotation can be to transition from a use position (e.g., forward-facing or rear-facing) to a loading position (e.g., a sideways orientation, such as left-facing or right-facing). In other embodiments, the rotation can be limited to 180 degrees, allowing for a transition from forward-facing to rear-facing, and angles therebetween. Additionally, in some embodiments, a full 360-degree rotation can be provided, allowing for rear-facing, forward-facing, left-facing, right-facing, and angles therebetween. In some embodiments, the second positioning element 314 can provide for sliding or translational movement of the child car seat 306 relative to the first positioning element 312 in any angular or orientation direction. In other embodiments, sliding or translational movement may be locked relative to the first positioning element 312 and / or support base 308 except when the first positioning element 312 is in a particular predetermined position (e.g., only forward / backward and / or right / left orientations, excluding angles therebetween).

[0059] It will be understood that the right and left directions are toward the side of the vehicle and, therefore, toward the vehicle door. Thus, a child restraint system 300 with rotation capability allows a caregiver to rotate the child seat 306 from a transport position (e.g., forward-facing or rear-facing) to a loading position (e.g., sideways). The sideways orientation may provide the caregiver with improved ease of use and access for loading and unloading a child into and from the child seat 306. According to some embodiments of the present disclosure, a child restraint system is provided that allows the child seat to slide and rotate outward toward the vehicle door, thus improving loading and unloading a child into and out of the child seat.

[0060] 4, a schematic diagram of a child restraint system 400 according to an embodiment of the present disclosure is shown. The child restraint system 400 may be similar to the child restraint systems shown and described above. The child restraint system 400 includes a child seat 402 mounted to a support base 404. The child seat 402 may be a convertible child seat, an infant car seat, or other seat for providing a seat or space for securing a child within a vehicle, etc. The support base 404 of the child restraint system 400 may be configured to be securely attached to a vehicle seat 401 or other vehicle structure.

[0061] The child car seat 402 may be movable relative to the support base 404. For example, one or more reclining structures 406 may be provided at the interface between the child car seat 402 and the support base 404. The reclining structures 406 may be configured to fixedly, selectively fixedly, or movably connect and attach the child car seat 402 to the support base 404. In some embodiments, the child car seat 402 may be permanently but movably mounted to the support base 404 via the reclining structures 406. In other embodiments, the child car seat 402 may be removably installed to the support base 404 via the reclining structures 406 and may movably recline along the reclining structures 406. The reclining structures 406 may be brackets or similar structures having tracks, slots, etc. to enable reclining and tilting of the child car seat 402 relative to the support base 404. Referring to FIG. 4, the reclining mechanism 406 allows adjustment of the child seat 402 in the xz plane, providing reclining movement in the forward / backward (+x / -x) and up / down (+z / -z) directions.

[0062] In addition to the reclining structure 406, the support base 404, in this configuration, includes a positioning assembly 405. The positioning assembly 405 is configured to provide additional degrees of freedom of movement or adjustment of the child seat 402. The positioning assembly 405 includes a first positioning element 408, a second positioning element 410, and a third positioning element 412. While shown with three separate and distinct positioning elements, other configurations may provide fewer or more positioning elements that combine or separate the various functions described herein and / or provide additional functions. The positioning elements may be arranged in a plate-like structure as shown, or may take other forms or shapes without departing from the scope of the present disclosure.

[0063] In this exemplary, non-limiting embodiment, the reclining structure 406 is fixedly attached to or is part of (e.g., integrally formed with) the first positioning element 408. In other embodiments, the reclining structure 406 is selectively detachable from the first positioning element 408. The child seat 402 may be selectively movable relative to the reclining structure 406 to provide reclining or tilting movement for the child seat 402 relative to the support base 404 or the vehicle seat 401 (e.g., in the xz plane). In this exemplary configuration, the first positioning element 408 is a top layer to which the reclining structure 406 and / or the child seat 402 may be attached (e.g., permanently or removably). The first positioning element 408 may be configured to slide relative to the rest of the support base 404. For example, the first positioning element 408 may be slidable on and / or relative to the second positioning element 410. In the orientation of Figure 4, the first positioning element 408 may slide on or relative to the second positioning element 410 in the +x and -x directions.

[0064] The second positioning element 410 is disposed between the first positioning element 408 and the third positioning element 412. The second positioning element 410 may be configured to pivot or rotate relative to the other positioning elements 408, 412 and / or the support base 404. In one non-limiting example, the rotation provided by the second positioning element 410 may be rotation about a vertical axis (e.g., the z-axis in FIG. 4 ) passing through each of the positioning elements 408, 410, 412 (e.g., perpendicular to a plane (x-y plane) defined by the second positioning element 410). In one embodiment, when the second positioning element 410 rotates about the z-axis, the first positioning element 408 rotates therewith. Thus, the sliding direction of the first positioning element 408 may change based on the orientation of the second positioning element 410. As described above, in the configuration and orientation of FIG. 4 , the first positioning element 408 is slidable in the +x direction and the −x direction. However, when the second positioning element 410 is rotated 90 degrees, the sliding direction of the first positioning element 408 can change such that it is slidable in the +y direction and the −y direction.

[0065] The third positioning element 412 may be a stationary positioning element or may define one or more frames or tracks on which one or both of the first positioning element 408 and the second positioning element 410 may move (e.g., slide, rotate, etc.). In some embodiments, the second positioning element 410 may include a frame or track on which the first positioning element 408 may move (e.g., slide). In some embodiments, the third positioning element 412 may be integrally formed with or defined by the support base 404.

[0066] In this exemplary configuration, child restraint system 400 includes various other features. For example, child restraint system 400 may include a load leg 414 at a forward end of support base 404. In some configurations, load leg 414 may be pivotally or rotatably attached to a bottom surface of third positioning element 412. Child restraint system 400 may also include an anchoring mechanism 416. The anchoring mechanism 416 may be configured as a latch or anchor mechanism. This latch or anchoring mechanism is sometimes referred to as a "Child Lower Anchors and Tethers" (e.g., a LATCH system). Alternatively, or in addition, anchoring mechanism 416 may provide for releasable securement of child restraint system 400 to vehicle seat 401 via a vehicle belt associated with vehicle seat 401 or by other means or mechanisms. Anchoring mechanism 416 may be connected to child restraint system 400 at support base 404 (e.g., connected to a bottom surface of third positioning element 412). The support base 404 may also include an optional rebound bar 418, such as for use in a rear-facing orientation (eg, as shown in illustrative FIG. 4).

[0067] 5, a schematic diagram of a child restraint system 500 according to an embodiment of the present disclosure is shown. The child restraint system 500 may be similar to the child restraint systems shown and described above. The child restraint system 500 includes a child seat 502 mounted on a support base 504. The child seat 502 may be a convertible child seat, an infant car seat, or other seat for providing a seat or space for securing a child within a vehicle, etc. The support base 504 of the child restraint system 500 may be configured to be securely attached to a vehicle seat 501 or other vehicle structure.

[0068] In this configuration, the connection between the support base 504 and the child seat 502 includes a positioning assembly 505 for adjusting the orientation and position of the child seat 502 relative to the support base 504. The positioning assembly 505 includes a reclining structure 506 for tilting movement, a first positioning element 508 (e.g., for sliding), a second positioning element 510 (e.g., for rotating or pivoting), and a third positioning element 512 (e.g., a stationary positioning element). The support base 504 includes a load leg 514 and an anchoring mechanism 516. In this configuration, the rebound bar 518 is integrally formed with the material of the support base 504. In this configuration, the third positioning element 512 is an integral part of the support base 504.

[0069] 6A and 6B, a schematic diagram of a child restraint system 600 according to one embodiment of the present disclosure is shown. The child restraint system 600 may be similar to the child restraint systems shown and described above. The child restraint system 600 includes a child seat 602 mounted on a support base 604 having a positioning assembly 605. The child seat 602 may be a convertible child seat, an infant car seat, or other seat for providing a seat or space for securing a child within a vehicle, etc. The support base 604 of the child restraint system 600 may be configured to be securely attached to a vehicle seat or other vehicle structure.

[0070] The configurations of Figures 6A and 6B are similar to the configuration shown and described in Figure 4. For example, as shown, child restraint system 600 includes a positioning assembly 605 having a first positioning element 606, a second positioning element 608, and a third positioning element 610. While not labeled for clarity and brevity, child restraint system 600 and / or its support base 604 may include load legs, rebound bars, mounting brackets, etc. (e.g., for tilt / recline), and / or anchoring mechanisms. Figure 6A illustrates child restraint system 600 in a first position or state (e.g., a transfer position), and Figure 6B illustrates child restraint system 600 in a second position or state (e.g., a loading position). In this exemplary configuration, child seat 602 is in a non-removable configuration, where child seat 602 is not removable from support base 604. However, other embodiments contemplate configurations in which the child seat is removable from the support base 604 .

[0071] In this exemplary configuration, the first positioning element 606 may be configured to slide relative to the second positioning element 608 and support the child seat 602 such that the child seat 602 moves as the first positioning element 606 moves. The second positioning element 608 may be rotatable relative to the third positioning element 610, such that the first positioning element 606 and the child seat 602 rotate with the rotation of the second positioning element 608. The third positioning element 610 may be a fixed or stationary positioning element for supporting and securing the child restraint system 600 on a vehicle or vehicle seat.

[0072] In a first position (e.g., the transfer position (FIG. 6A)), the positioning elements 606, 608, 610 are stacked such that the first positioning element 606 is positioned above the second positioning element 608, which is positioned above the third positioning element 610. Furthermore, each positioning element 606, 608, 610 has a primary or long axis that is aligned with the other positioning elements 606, 608, 610 when in the first position, resulting in a relatively low or narrow profile. Such a low or narrow profile may result in a fit in or on a vehicle seat and may result in positioning and orienting an occupant within the child safety seat 602 so that it is securely secured within the vehicle.

[0073] To transition to a second position (e.g., a loading position; FIG. 6B ), the second positioning element 608 may be rotated relative to the third positioning element 610. As shown in FIG. 6B , as the second positioning element 608 rotates (e.g., 90°), the first positioning element 606 may also rotate therewith. That is, the first positioning element 606 may be positionally attached to the second positioning element 608 (e.g., the first positioning element 606 may be carried by the second positioning element 608 during rotation) such that rotation of the second positioning element 608 causes rotation of the first positioning element 606. As the second positioning element 608 rotates, the first positioning element 606 may then slide relative to the second positioning element 608. The sliding movement of the first positioning element 606 causes the child seat 602 to slide relative to both the third positioning element 610 and the second positioning element 608. Thus, the child car seat 602 can be rotated and translated from the transfer position (FIG. 6A) to the loading position (FIG. 6B), thus improving ease of use for the caregiver. When installed in a vehicle, the loading position (FIG. 6B) is an orientation in which the front of the child car seat 602 faces the vehicle door, providing the caregiver with access to the child car seat 602 without having to enter the vehicle (e.g., bend down inside the vehicle).

[0074] 7A and 7B, a schematic diagram of a child restraint system 700 according to one embodiment of the present disclosure is shown. The child restraint system 700 may be similar to the child restraint systems shown and described above. The child restraint system 700 includes a child car seat 702 mounted on a support base 704 having a positioning assembly. The child car seat 702 may be a convertible car seat, an infant car seat, or other seat for providing a seat or space for securing a child within a vehicle, etc. The support base 704 of the child restraint system 700 may be configured to be securely attached to a vehicle seat or other vehicle structure.

[0075] The configurations in Figures 7A and 7B are similar to those shown and described above. For example, as shown, child restraint system 700 includes a support base 704 having a positioning assembly with a first positioning element 706, a second positioning element 708, and a third positioning element 710. While not labeled for clarity and brevity, child restraint system 700 and its support base 704 may include load legs (e.g., for tilt / recline), rebound bars, mounting brackets, etc., and / or fastening mechanisms. Figure 7A illustrates child restraint system 700 in a first temporary position (e.g., transitioning between the transfer position and the loading position), and Figure 7B illustrates child restraint system 700 in a second position (e.g., the loading position). Figures 7A and 7B illustrate the relative positions of child seat 702 and child restraint system 700 with respect to a vehicle side 703 (illustrated as a dashed line).

[0076] In this configuration, the first positioning element 706 may be configured to slide relative to the second positioning element 708 and support the child seat 702 such that the child seat 702 moves as the first positioning element 706 moves. The second positioning element 708 may be rotatable relative to the third positioning element 710, such that the first positioning element 706 and the child seat 702 rotate with the rotation of the second positioning element 708. The third positioning element 710 may be a fixed or stationary positioning element for supporting and securing the child restraint system 700 on the vehicle or vehicle seat.

[0077] 7A , the child seat 702, the first positioning element 706, and the second positioning element 708 are rotated relative to the third positioning element 710 of the support base 704. In this configuration, the child seat 702 is a rear-facing seat with the foot end 712 of the child seat 702 and the head end 714 of the child seat 702 rotated to the transfer position and toward the loading position. In this intermediate position, the child seat 702 is still not moved relative to the first positioning element 706 and the second positioning element 708, but is rotated relative to the third positioning element 710. That is, the child seat 702 is rotated relative to the side of the vehicle 703 to provide improved access for a caregiver when loading or unloading a child into or from the child seat 702.

[0078] In Figure 7B, the child car seat 702 is moved in a sliding motion as the first positioning element 706 translates or slides relative to the second positioning element 708 (and relative to the third positioning element 710). As exemplarily shown in Figure 7B, compared to Figure 7A, the child car seat 702 extends outward to the side of the support base 704 (e.g., outward from the vehicle side surface 703). This extension to the side may provide improved accessibility and ease of use of the child car seat 702 (e.g., when placing a child in or removing a child from the child car seat 702). By allowing the child car seat 702 to extend outward from the side of the vehicle through the vehicle side surface 703, improved ease of access and use of the child car seat 702 is provided to the caregiver.

[0079] 8A-8D, a schematic diagram of a child restraint system 800 according to one embodiment of the present disclosure is shown. Child restraint system 800 may be similar to the child restraint systems shown and described above. Child restraint system 800 includes a child car seat 802 mounted to a support base 804. Child car seat 802 may be a convertible car seat, an infant car seat, or other seat for providing a seat or space for securing a child within a vehicle, etc. Support base 804 of child restraint system 800 may be configured to be securely attached to a vehicle seat or other vehicle structure.

[0080] The configurations in Figures 8A-8D are similar to those shown and described above. For example, as shown, child restraint system 800 includes a support base 804 having a positioning assembly 805 having a first positioning element 806, a second positioning element 808, and a third positioning element 810. While not labeled for clarity and brevity, child restraint system 800 and its support base 804 may include load legs (e.g., for tilt / recline), rebound bars, mounting brackets, etc., and / or securing mechanisms. Figures 8A-8B illustrate child restraint system 800 in a first position (e.g., a transfer position), and Figures 8C-8D illustrate child restraint system 800 in a second position (e.g., a loading position). In this configuration, the first positioning element 806 may be configured to slide relative to the second positioning element 808 and support the child seat 802 such that the child seat 802 moves as the first positioning element 806 moves. The second positioning element 808 may be rotatable relative to the third positioning element 810, such that the first positioning element 806 and the child seat 802 rotate with the rotation of the second positioning element 808. The third positioning element 810 may be a fixed or stationary positioning element for supporting and securing the child restraint system 800 on the vehicle or vehicle seat.

[0081] 8A and 8B , positioning assembly 805 includes or defines a first pivot axis 812 and a second pivot axis 814. First pivot axis 812 is defined between third positioning element 810 and second positioning element 808, or by interaction between third positioning element 810 and second positioning element 808, and second pivot axis 814 is defined between second positioning element 808 and first positioning element 806, or by interaction between second positioning element 808 and first positioning element 806. In this configuration, first pivot axis 812 defines an axis of rotation or pivot point about which second positioning element 808 can rotate relative to third positioning element 810. In this configuration, the second pivot axis 814 defines an axis of rotation or pivot point about which the first positioning element 806 can be rotated relative to the second positioning element 808. Thus, the orientation of the first positioning element 806 and the second positioning element 808 (as shown in FIG. 8B ) can be rotated as a single unit or structure about the first pivot axis 812 relative to the third positioning element 810. As a second action, or simultaneously, the first positioning element 806 can be rotated relative to the second positioning element 808 about the second pivot axis 814. In the second position ( FIG. 8D ), the child seat 802 can be slidably moved or translated relative to the first positioning element 806.

[0082] 9A-9C, a schematic diagram of the use of a child restraint system 900 according to one embodiment of the present disclosure is shown. The child restraint system 900 may be similar to the configurations shown and described above. In these exemplary embodiments, FIGS. 9A-9C represent a bottom view (e.g., looking upward from the vehicle seat in which the child restraint system 900 is installed). The child restraint system 900 includes a child seat 902 supported on a support base 904 that includes a positioning assembly 906 to allow adjustment of the position and orientation of the child seat 902 relative to a vehicle side 908. The vehicle side 908 may represent an opening door of the vehicle, allowing access to the child seat 902 and allowing removal of a child from the child seat 902. The positioning assembly 906, in this exemplary configuration, includes a first positioning element 910 and a second positioning element 912. The first positioning element 910 may be a rotating element rotatable about a swivel 914, and the second positioning element 912 includes a track 916 that allows the second positioning element 912 to slide relative to the first positioning element 910. The second positioning element 912 is rotatably coupled to the first positioning element 910 such that when the first positioning element 910 is rotated (e.g., by manually pivoting the child seat 902), the second positioning element 912 also rotates.

[0083] FIG. 9A illustrates a transfer position in which the track 916 is positioned in the fore-aft direction. By rotating the child seat 902 or the first positioning element 910, the child seat 902 can be rotated to face the vehicle side 908, as shown in FIG. 9B. As shown in FIG. 9B, the child seat 902 is closer to the vehicle side 908 than when in the transfer position (FIG. 9A). However, as shown in FIG. 9C, the child seat 902 can slide outward toward (or through) the vehicle side 908, further improving access and use of the child seat 902. As shown in FIG. 9C, the second positioning element 912 extends toward the vehicle side 908, thereby supporting the child seat 902, which also extends toward the vehicle side 908.

[0084] 10A-10C, schematic diagrams of a positioning assembly 1000 are shown, according to one embodiment of the present disclosure. FIG. 10A illustrates an isometric view of the positioning assembly 1000, FIG. 10B illustrates the positioning assembly 1000 in a first position or orientation (e.g., a transfer position), and FIG. 10C illustrates the positioning assembly 1000 in a second position or orientation (e.g., a loading position). The components of the positioning assembly 1000 may be used with child seats and / or child restraint systems, as described herein, or may be used with other types of child seats and / or configurations thereof.

[0085] The positioning assembly 1000, as illustrated, includes a stationary positioning element 1002 and a rotational positioning element 1004. In a non-limiting example, the stationary positioning element 1002 may be equivalent to the third positioning element described above, and the rotational positioning element 1004 may be equivalent to the second positioning element described above. In this exemplary configuration, a sliding or translating positioning element (e.g., the first positioning element described above) is omitted, although such a sliding or translating element may be configured to be attached to an upper surface of the rotational positioning element 1004 and disposed in a sliding or translating relationship with the rotational positioning element 1004. The stationary positioning element 1002 may be configured to seat on a vehicle seat when installed in a vehicle and disposed in a fixed relationship with the vehicle seat. While not illustrated, the first positioning element 1002 and the second positioning element 1004 may include, without limitation, load legs, rebound bars, mounting brackets, reclining structures, etc., or may be configured to be mounted on the positioning elements, and may be part of a support base for a child restraint system, as described herein.

[0086] In this configuration, the stationary positioning element 1002 includes two first tracks 1006a, 1006b, and the rotational positioning element 1004 includes two second tracks 1008a, 1008b. While shown with two tracks each, other embodiments may employ a single track, and other configurations may employ three or more tracks. In the exemplary configuration of FIGS. 10A-10C, the first pair of tracks 1006a, 1008a may be positioned or aligned such that the first post 1010a passes through each of the first track 1006a and the second track 1008a. Similarly, the second pair of tracks 1006b, 1008b may be positioned or aligned such that the second post 1010b passes through each of the first track 1006b and the second track 1008b. In some embodiments, posts 1010a, 1010b are not fixed within or to stationary positioning element 1002, but may be part of stationary positioning element 1002, allowing movement of posts 1010a, 1010b along each pair of tracks 1006a, 1008a, 1006b, 1008b. In other embodiments, posts 1010a, 1010b may be part of a slide or translation layer (e.g., the first positioning element described above) so long as slide / translation tracks or the like are provided to allow such a slide or translation layer to move relative to rotational positioning element 1004.

[0087] 11A-11E, schematic diagrams of the operation of the positioning assembly 1100 and child car seat 1101 are shown. FIG. 11A illustrates an isometric view of the positioning assembly 1100, FIG. 11B illustrates the positioning assembly 1100 in a first position or orientation (e.g., a transfer position), and FIG. 11C illustrates the positioning assembly 1100 in a second position or orientation (e.g., a loading position). FIGs. 11D and 11E illustrate the child car seat 1101 supported on a support base 1103 with the positioning assembly 1100 positioned between the child car seat 1101 and the support base 1103, and illustrate the orientation of the child car seat 1101 and the positioning assembly 1100.

[0088] The positioning assembly 1100, as shown, includes a stationary positioning element 1102 and a rotational positioning element 1104. In a non-limiting example, the stationary positioning element 1102 may be equivalent to the third positioning element described above, and the rotational positioning element 1104 may be equivalent to the second positioning element described above. In this exemplary configuration, a sliding or translating layer (e.g., the first positioning element described above) is omitted, although such a sliding or translating layer, which may be configured to be attached to an upper surface of the rotational positioning element 1104, may be disposed in a sliding or translating relationship with the rotational positioning element 1104. The stationary positioning element 1102 may be configured to seat on a vehicle seat when installed in a vehicle and be disposed in a fixed relationship with the vehicle seat.

[0089] In this configuration, the stationary positioning element 1102 and the rotational positioning element 1104 include overlapping or aligned tracks 1106, 1108. The tracks 1106, 1108 are arranged as a “cross” or “T” shape that allows one or more posts 1110 a, 1110 b to move along the tracks 1106, 1108, or the tracks 1106, 1108 to move along the posts 1110 a, 1110 b. This results in relative motion between the stationary positioning element 1102 and the rotational positioning element 1104. The change in orientation of the positioning elements 1102, 1104 and the change in the relative position of the posts 1110 a, 1110 b illustrate a change from a first position or orientation (e.g., a transfer position) to a second position or orientation (e.g., a loading position). It will be appreciated that another positioning element may be movably coupled to the rotational positioning element 1104 to provide sliding movement (eg, for a child seat 1101 attached to the support base 1103).

[0090] During rotation of the positioning assembly 1100, the rotational positioning element 1104 rotates about a pivot axis extending through the post 1110a. The position of the pivot axis translates along the track 1108, such that after the positioning assembly 1100 rotates from the first rotational position (FIG. 11B) to the second rotational position (FIG. 11C), the pivot axis of the positioning assembly 1100 in the second rotational position is spaced apart from the pivot axis of the positioning assembly 1100 in the first rotational position.

[0091] As shown in FIGS. 11D-11E, the child car seat 1101 can be rotated in orientation (e.g., rearward and sideward) relative to the vehicle configuration by operation and use of the positioning assembly 1100. In FIG. 11D, the child car seat 1101 is oriented in a travel position. In the travel position, the foot section 1112 of the child car seat 1101 is oriented toward the rear or rearward direction of the vehicle, and the head section 1114 of the child car seat 1101 is oriented toward the front or forward direction of the vehicle. By operation of the positioning assembly 1100, the child car seat 1101 can be rotated and extended to the side of the vehicle. For example, as shown in FIG. 11E, the head section 1114 and foot section 1112 of the child car seat 1101 are oriented toward the side and perpendicular to the fore-aft direction.

[0092] 12A-12E, schematic diagrams of the operation of the positioning assembly 1200 and child car seat 1201 are shown. FIG. 12A illustrates an isometric view of the support base 1203, FIG. 12B illustrates the positioning assembly 1200 in a first position or orientation (e.g., a transfer position), and FIG. 12C illustrates the positioning assembly 1200 in a second position or orientation (e.g., a loading position). FIGs. 12D and 12E illustrate the child car seat 1201 supported on the support base 1203 with the positioning assembly 1100 positioned between the child car seat 1201 and the support base 1203, and illustrate the orientation of the child car seat 1201 and the positioning assembly 1100.

[0093] The positioning assembly 1100, as illustrated, includes a stationary positioning element 1202 and a rotational positioning element 1204. In a non-limiting example, the stationary positioning element 1202 may be equivalent to the third positioning element described above, and the rotational positioning element 1204 may be equivalent to the second positioning element described above. In this exemplary configuration, a sliding or translating layer (e.g., the first positioning element described above) is omitted, although such a sliding or translating layer, which may be configured to be attached to an upper surface of the rotational positioning element 1204, may be disposed in a sliding or translating relationship with the rotational positioning element 1204. The stationary positioning element 1202 may be configured to seat on a vehicle seat when installed in a vehicle and be disposed in a fixed relationship with the vehicle seat.

[0094] In this configuration, stationary positioning element 1202 includes one or more posts 1206 a, 1206 b, and rotational positioning element 1204 includes track 1208. Track 1208 is arranged as an arcuate cross shape or channel that allows posts 1206 a, 1206 b to move along track 1208 or track 1208 to move along posts 1206 a, 1206 b, 1210 b, resulting in relative motion between stationary positioning element 1202 and rotational positioning element 1204. The change in orientation of positioning elements 1202, 1204 and the change in position of posts 1206 a, 1206 b within track 1208 illustrate a change from a first position or orientation (e.g., a transfer position) to a second position or orientation (e.g., a loading position). It will be appreciated that another positioning element may be movably coupled to the rotational positioning element 1204 to provide a sliding movement (eg, for a child seat attached to the positioning assembly 1200).

[0095] As shown in Figures 12D and 12E, the child seat 1201 can be rotated in orientation (e.g., rearward and sideward) relative to the vehicle configuration by operation and use of the positioning assembly 1200. In Figure 12D, the child seat 1201 is oriented in a travel position. In the travel position, the foot section 1212 of the child seat 1201 is oriented toward the rear or rearward direction of the vehicle, and the head section of the child seat 1201 is oriented toward the front or forward direction of the vehicle. By operation of the positioning assembly 1200, the child seat 1201 can be rotated and extended to the side of the vehicle. For example, as shown in Figure 12E, the foot section 1212 of the child seat 1201 can be extended vertically in the fore-aft direction, facing sideways.

[0096] The positioning assemblies 1000, 1100, and 1200 shown and described above can be configured to provide both rotation and translation simultaneously. For example, when two exemplary positioning elements are moved relative to one another, the arrangement of tracks and other features can be such that when rotation occurs, translation also occurs, or when translation occurs, rotation also occurs. As shown in each of FIGS. 10C, 11C, and 12C, portions of the positioning assemblies 1000, 1100, 1200 extend laterally and are rotated relative to the anterior-posterior direction. In the configuration of the positioning assemblies 1000, 1200, the tracks can be arranged such that the motion defined and enabled by the tracks is a curvilinear motion that provides both rotation and translation.

[0097] While shown with a post-and-track configuration, such a configuration is not intended to be limiting. The illustrated configuration provides a system with minimal moving parts, thus improving the simplicity of the system. However, according to some embodiments, additional components and mechanisms may be provided to assist in the movement of the various layers and / or the movement of the child car seat between the transfer position and the loading position. For example, in some configurations, a pulley system, a gear system, an arm-based system, a pinion-and-gear system, a pinion-and-track, or rails may be used in place of the post-and-track configuration.

[0098] As described above, the child car seat of the presently disclosed embodiments is configured to be movable relative to the support base. The support base of the child restraint systems described herein provides multiple degrees of freedom or movement. The movement of the child car seat relative to the support base (provided by elements of the support base) allows for improved loading and unloading of a child into and from the child car seat.

[0099] 13A-13D, schematic diagrams of a child restraint system 1300 are shown in accordance with one embodiment of the present disclosure. The child restraint system 1300 includes a child seat 1302 attached to a support base 1304 and movable relative to the support base 1304. FIG. 13A illustrates the child seat 1302 in isolation with a reclining structure 1303 attached. FIG. 13B illustrates the support base 1304 in isolation, including a positioning assembly 1305. FIG. 13C illustrates the child restraint system 1300 in a transfer position, and FIG. 13D illustrates the child restraint system 1300 in a loading position. The child seat 1302 may be releasably attached, connected, or mounted to the support base 1304 via the reclining structure 1303 and / or positioning assembly 1305, or may be permanently secured to the support base 1304. In some embodiments, the child seat 1302 (or a portion thereof) may be completely removable from the support base 1304 so that the support base 1304 may remain in the vehicle and a caregiver may place a child in the child seat 1302 or remove the child seat 1302 from the vehicle without removing the support base 1304 from the vehicle.

[0100] As shown in FIG. 13A , the child car seat has a first end 1306 and a second end 1308, and the support base 1304 has a first end 1310 and a second end 1312. The first end 1306 of the child car seat 1302 may be the foot or leg end of the seat (e.g., when a child is seated in the child car seat 1302), and the second end 1308 may be the head end of the child car seat 1302. In this exemplary embodiment, the child car seat 1302 is a rear-facing child car seat, as shown in FIG. 13B . The child car seat 1302 extends in a front-to-rear direction when in a travel position (e.g., as shown in FIGS. 13B-13C ), but generally defines a seat axis 1314 defined between the first end 1306 and the second end 1308.

[0101] 13B, the first end 1310 of the support base 1304 may be a forward end (e.g., an end aligned with the direction of vehicle motion), and the second end 1312 of the support base 1304 may be a rearward end. As a result, the support base 1304 (with its stationary portion) may define a base axis 1316 between the first end 1310 and the second end 1312.

[0102] FIG. 13C shows the child restraint system 1300 in a first position (e.g., a transfer position). In the first position, the seat axis 1314 and the base axis 1316 are aligned or parallel. As a result, the child restraint system 1300 has a relatively narrow profile to fit the vehicle seat. FIG. 13D shows the child restraint system 1300 in a second position (e.g., a loading position). In the second position, the seat axis 1314 is rotated relative to the base axis. In some embodiments, the angle between the seat axis 1314 and the base axis 1316 can be adjusted between zero (where "zero" is parallel or aligned, as shown in FIG. 13C) and a full 360° rotation. In other embodiments, the amount of relative rotation can be limited between zero and some angle less than 360°. For example, as shown in FIG. 13D, in the second position, the seat axis 1314 can be rotated 90° relative to the base axis 1316. That is, in the second position, the seat axis 1314 may be perpendicular to the base axis 1316 .

[0103] In some embodiments according to the present disclosure, the child seat 1302 may also be translatable relative to the support base 1304. Thus, in some embodiments, the child seat 1302 may be translatable or slidable along the seat axis 1314. In some configurations, the sliding movement may be limited to the loading position only (FIG. 13D). In other configurations, the child seat 1302 may be slidable relative to the support base 1304 in any position, but particularly in the first position (FIG. 13C) and the second position (FIG. 13D).

[0104] The child car seat 1302 includes or defines a seating area 1318 on which a child can sit and be held on the child car seat 1302. A seat axis 1314 passes through the seating area 1318 and defines the general orientation that a child seated in the child car seat 1302 faces. As shown in FIG. 13C , the seating area 1318 is generally axially aligned with the base axis 1316 (i.e., the seat axis 1314 and the base axis 1316 are parallel). When the child car seat 1302 is rotated from a first position ( FIG. 13C , e.g., the transport position) to a second position ( FIG. 13D , e.g., the load position), the seating area 1318 is rotated away from the base axis 1316. In this position, the seating area 1318 is located closer to (or extends further from) the vehicle door compared to the transport position. 13C-13D, the support base 1304 defines a base axis 1316 that extends from the rear end of the support base 1304 (e.g., end 1312) to the front end of the support base 1304 (e.g., end 1310). The positioning assembly 1305 is configured such that in a first rotational position (e.g., FIG. 13C), the center of gravity of the child car seat (e.g., center of the seating area 1318) intersects the base axis 1316, and in a second rotational position, the center of gravity of the child car seat (e.g., center of the seating area 1318) is offset from the base axis 1316. Furthermore, during rotation of the positioning assembly 1305 from the first rotational position to the second rotational position, the front end of the child car seat (e.g., end 1306) moves along a partial elliptical path.

[0105] According to some embodiments, as shown schematically in FIG. 13D , the child restraint system 1300 may include one or more locking mechanisms 1320. The locking mechanisms 1320 may be actuatable or operable elements that can selectively secure one or more elements of the child restraint system 1300 together. For example, a detent-type locking mechanism may be disposed between the positioning elements of the positioning assembly 1305 to selectively secure relative movement. That is, in a locked state, one or more of the positioning elements may be secured together and therefore move (or not move) together. When manipulation or movement of the child seat 1302 is desired, one or more of the locking mechanisms 1320 may be unlocked to allow relative movement, as shown and described herein. Thus, for example, when the child car seat 1302 is moved to the loading position ( FIG. 13D ), a locking mechanism 1320 can be used to lock the position of the child car seat 1302 relative to the support base 1304 so that the child car seat 1302 does not slide or rotate during loading or unloading of a child into or from the child car seat 1302. The locking mechanism 1320 can be a detent, spring lock, snap, cotter pin, lockable gear or track (e.g., for rotation or translation), etc. The locking mechanism 1320 can be used to both secure or lock the position of the child car seat 1302 relative to the support base 1304 (e.g., either or both of the transfer position and loading position). In some non-limiting embodiments, the locking mechanism 1320 can always be in a locked state unless activated by a user (e.g., a caregiver), such that the default state is to lock the position of the child car seat 1302 relative to the support base 1304 unless the locking mechanism 1320 is operated. In some non-limiting embodiments, the opposite may be true, with the locking mechanism remaining in an unlocked state except when used by a caregiver to secure the position of the child seat 1302 relative to the support base 1304.

[0106] Advantageously, embodiments of the present disclosure provide an improved child seat and / or child restraint system for use in a vehicle. The child restraint system includes a child seat movably mounted to a support base. The support base can provide multiple degrees of freedom or movement, including, but not limited to, rotation and sliding. The multiple degrees of movement can be provided by a multi-layer support base. Thus, even when the support base is fixedly attached to the vehicle (or vehicle seat), the child seat can be rotated and moved. Improved use and ease of use are therefore provided to caregivers when placing a child in or removing a child from the child seat. According to some embodiments of the present disclosure, the support base of the child restraint system can include multiple layers that are movable relative to each other. The layers can provide both rotational and translational movement, providing a wider range of movement compared to conventional child restraint systems.
