The first opening 320(1) has a dimension, such as a height, less than a dimension of the first belt hole 318(1) to provide an interference that restricts inadvertent removal of the restraining belt from the first belt hole 318(1).

    [0086] The at least one belt guide 304 includes a second belt guide 304(2). The second belt guide 304(2) is offset from the first belt guide 304(1) along the third direction D.sub.3. The second belt guide 304(2) is configured to be movably coupled to the second side 324 of the seat body 302 such that the second belt guide 304(2) is configured to transition between a deployed position (FIG. 16) in which the second belt guide 304(2) protrudes upward from the second seating surface 306, and a storage position (FIG. 17) in which the second belt guide 304(2) is stowed in at least one storage cavity 310 in the seat body 302. In some embodiments, the second belt guide 304(2) is configured to be pivotably coupled to the seat body 302 such that the second belt guide 304(2) is configured to rotate about an axis A.sub.P that extends along the first direction D.sub.1. The belt-positioning seat 300 includes a hinge 305 that couples the second belt guide 304(2) to the seat body 302. In some other embodiments, the second belt guide 304(2) is configured to be transitioned between the deployed and storage positions without rotating or by rotating and moving in another manner (e.g., translating).

    [0087] The second belt guide 304(2) is a rigid body that extends upward from the seat body 302 when in the deployed position. In some embodiments, the second belt guide 304(2) is configured to be attached to the seat body 302 along a middle portion of the seat body 302 between the front and rear ends 316 and 314 such that the second belt guide 304(2) is spaced from the front and rear ends 316 and 314. In some embodiments, the rigid body has a plate-like shape. The second belt guide 304(2) has a second belt hole 318(2) configured to receive a restraining belt, such as a lap belt of a vehicle seatbelt. The second belt hole 318(2) is spaced above the second seating surface 306 to position the retraining belt over a child's lap when the second belt guide 304(2) is in the deployed position. The second belt hole 318(2) extends through the second belt guide 304(2).

    [0088] In some embodiments, the second belt guide 304(2) has an inner side configured to face the child when in the deployed position, and an outer side opposite the inner side.

In some embodiments, the second belt guide 304(2) has a second opening 320(2) at the front end of the second belt guide 304(2) open to the second belt hole 318(2). The second belt hole 318(2) is closed at a rear end of the second belt guide 304(2). In some embodiments, the restraining belt is received through the second opening 320(2) and into the second belt hole 318(2) along a direction extending from the front end 316 of the belt-positioning seat 300 to the rear end 314. The second opening 320(2) has a dimension, such as a height, less than a dimension of the second belt hole 318(2) to provide an interference that restricts inadvertent removal of the restraining belt from the second belt hole 318(2).

    [0089] The seat body 302 has the at least one storage cavity 310, such as a pair of storage cavities therein. The at least one storage cavity 310 includes a first storage cavity 310(1). The first storage cavity 310(1) is configured to receive the first belt guide 304(1) to store the first belt guide 304(1) therein. The first storage cavity 310(1) extends into the bottom surface 308 of the seat body 302, although embodiments in this disclosure are not so limited. For instance, in other embodiments, the first storage cavity 310(1) extends into the first side 322 and is closed at the bottom surface 308. The first belt guide 304(1) is then configured to translate out of the storage cavity 310 and rotate to protrude upwards.

    [0090] The at least one storage cavity 310 includes a second storage cavity 310(2). The second storage cavity 310(2) is spaced from the first storage cavity 310(1) along the third direction D.sub.3. The second storage cavity 310(2) is configured to receive the second belt guide 304(2) to store the second belt guide 304(2) therein. The second storage cavity 310(2) extends into the bottom surface 308 of the seat body 302, although embodiments of the present disclosure are not so limited. For instance, in other embodiments, the second storage cavity 310(2) extends into the second side 322 and is closed at the bottom surface 308. The second belt guide 304(2) is then configured to translate out of the storage cavity 310 and rotate to protrude upwards. In alternative embodiments, the seat body 302 has a single storage cavity that stores both the first and second belt guides 304(1) and 304(2).

    [0091] The seat body 302 is configured to be removably coupled to the seat bottom 200 of the main seat 12 in the receiving space 204 of the seat bottom 200. In some embodiments, belt-positioning seats include at least two couplers 326 configured to fasten the belt-positioning seat 300 to the seat bottom 200. The at least two couplers 326 are spaced from one another to define two separate fastening points between the belt-positioning seat 300 and the seat bottom 200. Each coupler 326 is disposed at the first side 322, the second side 324, the rear end 314, or the bottom surface 308.

    [0092] Each coupler 326 is configured in any suitable matter to fasten the belt-positioning seat 300 to the seat bottom 200). Each coupler 326 includes a securing surface configured to engage a corresponding securing surface of the seat bottom 200 to create an interference between the securing surfaces that fastens the belt-positioning seat 300 to the seat bottom 200. The interference prevents the belt-positioning seat 300 and the seat bottom 200 from moving relative to one another along at least one direction, such as along at least one, up to all, of the first direction D.sub.1, the second direction D.sub.2, and the third direction D.sub.3. Each coupler 326 includes an attachment protrusion having an outer securing surface configured to engage with an inner securing surface of a recess in the seat bottom 200 to secure the belt-positioning seat 300 in the receiving space 204 of the seat bottom 200. Additionally, or alternatively, in some embodiments, each coupler 326 includes an attachment recess having an inner securing surface configured to engage with an outer securing surface of an attachment protrusion of the seat bottom 200 to secure the belt-positioning seat 300 in the receiving space 204 of the seat bottom 200. In some embodiments, the attachment protrusion is a pin, a bar, a hook, or any other suitable protrusion. Each coupler 326 is a rigid coupler positionally fixed relative to the seat body 302 of the belt-positioning seat 300, or is a movable coupler such as a latch configured to move (e.g., retract and extend) relative to the seat body 302.

    [0093] In some embodiments, at least one of the couplers 326 includes a rigid protrusion 312 rigidly attached to the first side 322, the second side 324, the rear end 314, or the bottom surface 308 of the seat body 302, and configured to engage with a corresponding attachment recess 214(1) (FIGS. 6A and 6B) defined in the seat bottom 200. The protrusion 312 is integral and monolithic with the seat body 302 or otherwise rigidly attached thereto. In some embodiments, the rigid protrusion 312 is in the shape of a handle. In some embodiments, the handle defines a u shape. In some embodiments, the protrusion 312 extends from the rear end 314 of the belt-positioning seat 300. In some other embodiments, the protrusion 312 extends from one of the first or second sides 322 or 324.

    [0094] In some embodiments, the at least one coupler 326 includes at least one latch 328(1) or 328(2) movably attached to the seat body 302, and configured to engage with a corresponding attachment recess (e.g., 214(2), 214(3) of FIGS. 6A and 6B) in the seat bottom 200. The at least one latch 328(1) or 328(2) is configured to be transitioned between a latched position (FIG. 15) so as to fasten the belt-positioning seat 300 to the main seat 12 when received in the receiving space 204 of the main seat 12, and an unlatched position (FIG. 16) to unfasten the belt-positioning seat 300 from the main seat 12. The at least one latch 328(1) or 328(2), in some embodiments, is configured to extend out further from the seat body 302 in the latched position than in the retracted position. In some embodiments, the at least one latch 328(1) or 328(2) extends from at least one of the first side 322, the second side 324, the rear end 314, the front end 316, or the bottom surface 308 of the seat body 302. In some embodiments, the at least one latch 328(1) or 328(2) includes a plurality of latches 328(1), 328(2).

    [0095] According to some embodiments, a belt-positioning seat 300 includes an actuator 330 configured to be engaged by a user so as to transition the at least one latch 328(1) or 328(2) between the latched and unlatched positions. The actuator 330 includes an actuation surface, such as a handle or button, configured to be engaged by the user to actuate the actuator 330. The at least one latch 328(1) or 328(2) and the actuator 330 are configured to be implemented in any suitable manner. In some other embodiments, the actuator and latches are carried by the seat bottom 200, rather than the belt-positioning seat 300.

    [0096] Turning more specifically to FIGS. 15, 19, and 20, the at least two couplers 326 and the actuator 330 according to some embodiments are shown. In some embodiments, the at least two couplers 326 include a protrusion 312 that extends from the rear end 314 of the seat body 302. The protrusion 312 is a rigid coupler positionally fixed relative to the seat body 302 of the belt-positioning seat 300. The protrusion 312 defines a handle. In some embodiments, the handle has an opening therethrough for receiving a user's finger(s) when carrying the belt-positioning seat 300. In some embodiments, the handle can have a u shape. In some other embodiments, the protrusion 312 need not define a handle and has other shapes (e.g., L shape or T shape). The protrusion 312 is configured to be received in an attachment recess 214(1) in the backwall 212 of the seat bottom 200 (see FIGS. 6A and 6B). The protrusion 312 has a securing surface, such as an outer surface of the handle, that engages an inner surface of the recess 214(1) along the second direction D.sub.2 to prevent the protrusion 312 from moving relative to the seat bottom 200 along the second direction D.sub.2.

    [0097] The at least two couplers 326 include at least one movable latch, such as a first movable latch 328(1). The first movable latch 328(1) has an inner end 328a coupled to the actuator 330 such that movement of the actuator 330 along a first select direction D.sub.S1 causes movement of the first latch 328(1) along a second select direction D.sub.S2. In this example, the first select direction D.sub.S1 is aligned with the first direction D.sub.1 and the second select direction D.sub.S2 is aligned with the third direction D.sub.3; however, alternative examples of the present disclosure are not so limited. The inner end 328a is configured to be inside the seat body 302. The first movable latch 328(1) has an outer end 328b configured to extend out from the first side 322 of the seat body 302 through an opening in the seat body 302. The outer end 328b defines a protrusion that extends out from the first side 322. The protrusion extends out further from the seat body 302 in the latched position than in the retracted position. In some embodiments, the protrusion is configured to be completely retracted into the seat body 302 in the retracted position such that no portion of the protrusion extends outside of the seat body 302. The first latch 328(1) is configured to engage the recess 214(2) of the seat bottom 200 to prevent the belt-positioning seat 300 from moving relative to the seat bottom 200 along at least one, up to all, of the first direction D.sub.1, the second direction D.sub.2, and the third direction D.sub.3.

    [0098] In some embodiments, the at least one movable latch includes a second movable latch 328(2). The second movable latch 328(2) has an inner end 328a coupled to the actuator 330 such that movement of the actuator 330 along the first select direction D.sub.S1 causes movement of the second latch 328(2) along the second select direction D.sub.S2. The inner end 328a is configured to be disposed inside of the seat body 302. The second movable latch 328(2) has an outer end 328b configured to extend out from the second side 324 of the seat body 302 through an opening in the seat body 302. The outer end 328b defines a protrusion that extends out from the second side 322. The protrusion extends out further from the seat body 302 in the latched position than in the retracted position. In some embodiments, the protrusion is configured to be completely retracted into the seat body 302 in the retracted position such that no portion of the protrusion extends outside of the seat body 302. The first latch 328(1) is configured to engage the recess 214(2) of the seat bottom 200 to prevent the belt-positioning seat 300 from moving relative to the seat bottom 200 along at least one, up to all, of the first direction D.sub.1, the second direction D.sub.2, and the third direction D.sub.3.

    [0099] The actuator 330 includes an outer end 330a that defines an actuation surface 334 configured to be engaged by a user. The actuator 330 includes a handle 332 that defines the actuation surface 334. The actuation surface 334, and hence the handle 332, is configured to be exposed outside of the seat body 302 such that the actuation surface 334 is configured to be engaged by a user. In some embodiments, the actuation surface 334 is configured to be disposed at the front end 316 of the belt-positioning seat 300, and is configured to be exposed along the second seating surface 306. The actuation surface 334 is movable along the first select direction D.sub.S1 to move the at least one movable latch 328(1), 328(2) between the latched and unlatched positions. The actuator 330 includes an inner end 330b disposed within the seat body 302. The inner end 330b is configured to be coupled to the at least one movable latch 328(1), 328(2) such that movement of the actuator 330 along the first select direction D.sub.S1 causes movement of the at least one latch 328(1), 328(2) along the second select direction D.sub.S2.

    [0100] In some embodiments, the actuator 330 is configured to be movably coupled to the at least one latch 328 using a suitable mechanism that converts movement of the actuator 330 along the first select direction D.sub.S1 to movement of the at least one latch 328(1), 328(2) along the second select direction D.sub.S2. In some embodiments, the inner end 330b of the actuator 330 has one of a protrusion or a ramped surface, and the at least one latch 328(1), 328(2) has another of the protrusion or the ramped surface. The ramped surface is configured to be angled relative to the first select direction D.sub.S1. In some embodiments, the ramped surface extends inward as the ramped surface extends along a direction that extends from the outer end 330a of the actuator 330 to the inner end 330b of the actuator 330. Movement of the actuator 330 is configured to cause the protrusion to be guided along the ramped surface to cause the at least one latch 328(1), 328(2) to move along the second select direction D.sub.S2.

    [0101] FIGS. 19 and 20 show some embodiments in which the inner end 330b of the actuator 330 includes, for each of the at least one latch 328(1), 328(2), a protrusion 330c, and each of the at least one latch 328(1), 328(2) includes a ramped surface 328c. In particular, the inner end 330b of the actuator 330 includes first and second protrusions 330c that are offset from one another along the second select direction D.sub.S2. The inner end 328a of the first latch 328(1) has a ramped surface 328c that receives a first one of the protrusions 330c, and the inner end 328a of the second latch 328(2) has a ramped surface 328c that receives a second one of the protrusions 330c. Movement of the actuator 330 back and forth along the first select direction D.sub.S1 causes the first and second latches 328(1) and 328(2) to move towards and away from one another along the second select direction D.sub.S2 between the latched and unlatched positions. In some embodiments, the belt-positioning seat 300 includes at least one spring (not shown) configured to bias the at least one latch 328(1), 328(2) towards the latched position.

    [0102] Referring generally to FIGS. 1, 15, and 16, in some embodiments, the seat body 302 of the belt-positioning seat 300 is configured to interface with the harness 400. For example, the seat body 302 of the belt-positioning seat 300 is configured to be removably coupled to the seat bottom 200 of the main seat 12 in the receiving space 204 such that, when the seat body 302 is positioned in the receiving space 204, the crotch buckle 406 is positioned above the second seating surface 306 to removably fasten to the first and second straps 402 and 404 of the harness 400. The belt-positioning seat 300 includes at least one crotch strap opening 336 that extends into the second seating surface 306 and configured to couple the crotch buckle 406 to the belt-positioning seat 300. The crotch strap opening 336 extends entirely through the seat body 302.

    [0103] The webbing 410 of the crotch strap 408 extends through the crotch strap opening 336 such that the belt-positioning seat 300 is positioned between the seat bottom 200 and the crotch buckle 406. In some embodiments, the webbing 410 is attached to the seat bottom 200 and the crotch strap opening 336 is sized to receive the crotch buckle 406 therethrough as the belt-positioning seat 300 is received in the receiving space 204 of the seat bottom 200. In these embodiments, the child safety seat 10 is configured such that, when the belt-positioning seat 300 is removed from the main seat 12, the crotch buckle 406 remains attached to the seat bottom 200. Thus, an inner end of the webbing 410 is configured to be constrained by the seat bottom 200 against removal from the seat bottom 200. In some other embodiments, the webbing 410 is attached to the belt-positioning seat 300, and not the seat bottom 200, such that removal of the belt-positioning seat 300 from the child safety seat 10 causes the crotch buckle 406 to be removed along with the belt-positioning set 300 from the main seat 12. Thus, an inner end of the webbing 410 is configured to be constrained by the belt-positioning seat 300 against removal from the belt-positioning seat 300. In some embodiments, the belt-positioning seat 300 is configured such that, when the at least one belt guide 304 is stowed in the storage position, the at least one belt guide 304 does not obstruct the crotch strap opening 336 to prevent insertion or removal of the crotch buckle 406 through the crotch strap opening 336.

    [0104] The belt-positioning seat 300 includes at least one lap belt opening configured to receive at least one of the first and second straps 402 and 404 of the harness 400. In some embodiments, the belt-positioning seat 300 includes a first lap belt opening 338(1) configured to receive a portion of the first strap 402 therethrough. Additionally, or alternatively, in some embodiments, the belt-positioning seat 300 includes a second lap belt opening 338(2) configured to receive a portion of the second strap 402 therethrough. In some embodiments, each lap belt opening is configured to be open at the rear end 314 or at one of the sides 322 and 324 of the belt-positioning seat 300 so as to facilitate installation of a respective one of the first and second straps 402 and 404 into the lap belt opening, and removal of the respective one of the first and second straps 402 and 404 from the lap belt opening.

    [0105] Referring to FIGS. 21 and 22, a belt-positioning seat 300 is shown according to some embodiments. The belt-positioning seat 300 is similar to the belt-positioning seat 300 of FIGS. 15 to 18, with a few notable exceptions. The features of the belt-positioning seat 300 that differ from those of the belt-positioning seat 300 will now be described. All other features of the belt-positioning seat 300 may be understood with reference to the description of those features above in relation to the belt-positioning seat 300. In some embodiments, the belt-positioning seat 300 is configured to be devoid of the first and second lap belt openings 338(1) and 338(2). Instead, the belt-positioning seat 300 is configured such that the first and second straps 402 and 404 route up the first and second sides 322 and 324 of the belt-positioning seat 300 between the belt-positioning seat 300 and the sidewalls 210(1) and 210(2) of the main seat 12. In some embodiments, the first and second straps 402 and 404 are configured to be routed through lap belt openings as will be discussed further below in relation to FIGS. 23 and 24.

    [0106] The belt-positioning seat 300 includes a rotatable actuator 330, rather than the translatable actuator of the belt-positioning seat 300. Like the belt-positioning seat 300, the belt-positioning seat 300 includes at least one movable latch, such as a first movable latch 328(1), and optionally, a second movable latch 328(2). Each movable latch 328(1), 328(2) has an inner end 328a coupled to the actuator 330 such that rotation of the actuator 330 about an axis of rotation A.sub.L causes movement of the latch 328(1), 328(2) along a select direction D.sub.S. In this embodiment, the select direction D.sub.S is aligned with the third direction D.sub.3, and the axis of rotation A.sub.L is aligned with the select direction D.sub.S. However, alternative embodiments are not so limited. The inner end 328a is configured to be disposed inside of the seat body 302. Each movable latch 328(1), 328(2) has an outer end 328b configured to extend out from the first side 322 of the seat body 302 through an opening in the seat body 302. The outer end 328b includes a protrusion that extends out from the first side 322. The protrusion extends out further from the seat body 302 in the latched position than in the retracted position. In some embodiments, the protrusion is configured to be completely retracted into the seat body 302 in the retracted position such that no portion of the protrusion extends outside of the seat body 302. Each latch 328(1), 328(2) is configured to engage a recess 214(2), 214(3) of the seat bottom 200 so as to prevent the belt-positioning seat 300 from moving relative to the seat bottom 200 along at least one, up to all, of the first direction D.sub.1, the second direction D.sub.2, and the third direction D.sub.3.

    [0107] The actuator 330 includes an outer end 330a that defines an actuation surface 334 configured to be engaged by a user. The actuation surface 334 is configured to be exposed outside of the seat body 302 such that the actuation surface 334 is configured to be engaged by a user. In some embodiments, the actuation surface 334 is disposed at the front end 316 of the belt-positioning seat 300, and is exposed along the second seating surface 306. The actuation surface 334 is movable about the axis of rotation A.sub.L so as to move the at least one movable latch 328(1), 328(2) between the latched and unlatched positions. The actuator 330 includes an inner end 330b disposed within the seat body 302. The inner end 330b is configured to be coupled to the at least one movable latch 328(1), 328(2) such that rotation of the actuator 330 causes movement of the at least one latch 328(1), 328(2) along the select direction D.sub.S.

    [0108] The inner end 330b of the actuator 330 has a protrusion 330c for each of the at least one latch 328(1), 328(2), and each of the at least one latch 328(1), 328(2) includes a ramped surface 328c. In some embodiments, the inner end 330b of the actuator 330 includes first and second protrusions 330c that are offset from one another along the select direction D.sub.S. The inner end 328a of the first latch 328(1) has a ramped surface 328c that receives a first one of the protrusions 330c, and the inner end 328a of the second latch 328(2) has a ramped surface 328c that receives a second one of the protrusions 330c. Rotational movement of the actuator 330 causes the first and second latches 328(1) and 328(2) to move towards and away from one another along the select direction D.sub.S between the latched and unlatched positions. In at least some embodiments, the belt-positioning seat 300 includes at least one biasing member (not shown), such as a spring or resilient material, configured to bias the at least one latch 328(1), 328(2) towards the latched position.

    [0109] Turning now to FIGS. 23 and 24, a belt-positioning seat 300 is shown according to some embodiments. The belt-positioning seat 300 is similar to the belt-positioning seat 300 of FIGS. 15 to 18, with a few notable exceptions. The features of the belt-positioning seat 300 that differ from those of the belt-positioning seat 300 will now be described. All other features of the belt-positioning seat 300 may be understood with reference to the description of those features above in relation to the belt-positioning seat 300.

    [0110] Like the belt-positioning seat 300, the belt-positioning seat 300 includes a first lap belt opening 338(1) configured to receive a portion of the first strap 402 therethrough, and/or a second lap belt opening 338(2) configured to receive a portion of the second strap 402 therethrough. However, rather than extending into the rear end 314 of the belt-positioning seat 300, the first lap belt opening 338(1) extends into the first side 322 of the belt-positioning seat 300, and the second lap belt opening 338(2) extends into the second side 324 of the belt-positioning seat 300. In some embodiments, as shown, the first lap belt opening 338(1) extends into the first belt guide 304(1), such as into a lower end or the hinge 305 of the first belt guide 304(1). Additionally, or alternatively, in some embodiments, the first lap belt opening 338(1) extends into the seat body 302 at the first side 322.

Additionally, or alternatively, in some embodiments, the second lap belt opening 338(2) extends into the seat body 302 at the second side 324.

    Object Holders

    [0111] Conventional booster and convertible child seats often includes one or more object holders, such as one or more cup holders. Each object holder often extends beyond an outer perimeter of the seat. For example, each object holder commonly projects outwardly from a side of the seat and/or from the front of the seat. Accordingly, the box or other packaging that houses the seat during shipping defines an envelope sufficiently large to accommodate the object holder(s). In order to limit the size of the packaging, various child seats in some embodiments of the present disclosure are configured such that the object holder(s) is configured to be transitioned between a stowed position in which the object holder(s) does not extend beyond the perimeter of the seat, and a use position in which the object holder(s) are positioned for use by a child seated in the child seat. The object holder(s) is configured to be implemented in any child safety seat, including any of the child safety seats described herein and child safety seats that are not described herein.

    [0112] As described above in relation to FIGS. 6A and 6B, a child safety seat 10 in some embodiments includes at least one object holder, such as a pair of object holders 220(1) and 220(2). In some embodiments, at least one of the object holders 220(1) and 220(2) is a cupholder. In some embodiments, at least one of the object holders 220(1) and 220(2) is an object holder other than a cupholder, such as a snack holder. Each object holder 220(1) and 220(2) is configured to be disposed forward of a corresponding one of the sidewalls 210(1) and 210(2). Turning to FIGS. 25 to 29, in some embodiments, the at least one object holder 220(1), 220(2) is configured to be coupled to the seat bottom 200 such that the at least one object holder 220(1), 220(2) is rotatable relative to the seat bottom 200 between an extended position (e.g., FIG. 28) and a stowed position (e.g., FIG. 29), wherein the at least one object holder 220(1), 220(2) extends further out from the seat bottom 200 along the third direction D.sub.3, when the object holder 220(1), 220(2) is in the extended position than when the object holder 220(1), 220(2) is in the stowed position. In some embodiments, the at least one object holder 220(1), 220(2) extends outwardly from a corresponding one of the sidewalls 210(1), 210(2) along the third direction D.sub.3 when in the extended position, and is configured to be retracted relative to the sidewall 210(1), 210(2) along the third direction D.sub.3 when in the stowed position.

    [0113] Each object holder 220(1) and 220(2) has an upper end 220a and a lower end 220b that are spaced from one another along the second direction D.sub.2. The lower end 220b is configured to be closed, and the upper end 220a is configured to be open to receive objects therein. Each object holder 220(1) and 220(2) has a recess 220d that extends into the upper end 220a and terminates at the lower end 220b. Each object holder 220(1) and 220(2) has at least one sidewall 220c that extends between the upper and lower ends 220a and 220b to define a closed shape about the recess 220d. Each object holder 220(1) and 220(2) has the closed shape when in each of the extended and stowed positions. An entirety of each object holder is configured to rotate between the extended and stowed positions.

    [0114] The child safety seat 1 includes a coupler for each object holder 220(1) and 220(2) that rotatably couples the object holder to the seat bottom 200 such that the object holder rotates relative to the seat bottom 200 at a pivot axis A.sub.O between the extended and stowed positions. In some embodiments, each object holder 220(1) and 220(2) includes at least one of a protrusion 220e and an opening configured to engage another of a protrusion and an opening 210a of the seat bottom 200 so as to rotatably couple the object holder to the seat bottom 200. The other of the protrusion and the opening 210a is configured to be implemented at the front end of the seat bottom 200, such as at a front end of a corresponding one of the sidewalls 210(1) and 210(2). In some embodiments, as shown, each object holder 220(1) and 220(2) includes a protrusion 220e shaped as a shaft 220e received in an opening 210a of the corresponding one of the sidewalls 210(1) and 210(2). In some other embodiments (not shown), each object holder 220(1) and 220(2) includes an opening that receives a shaft of a corresponding one of the sidewalls 210(1) and 210(2). The object holder 220(1) and 220(2) is configured pivot about the pivot axis A.sub.O, which can be defined by the protrusion and/or the opening. In some embodiments, the pivot axis A.sub.O extends upwards, such as along or at an angle to the second direction D.sub.2.

    [0115] The child safety seat 1 includes a fastener 220f for each object holder 220(1), 220(2) configured to affix the object holder 220(1), 220(2) to the seat bottom 200 so as to limit removal of the object holder 220(1), 220(2) along at least one, such as all, of the first, second, and third directions D.sub.1, D.sub.2, and D.sub.3. Each fastener 220f is configured to limit removal of a corresponding object holder 220(1), 220(2) along the pivot axis A.sub.O. In some embodiments, each fastener 220f has a spring finger. Each spring finger is configured to be pivotably coupled to an object holder 220(1), 220(2) or the seat bottom 200 and is configured to engage another of the object holder 220(1), 220(2) or the seat bottom 200 so as to limit removal of the object holder 220(1), 220(2) from the seat bottom 200. However, each fastener 220f is configured to be implemented as any other suitable fastener.

    [0116] The child safety seat 1 includes a guide 234 for each object holder 220(1), 220(2) configured to guide movement of the object holder 220(1), 220(2) between the extended and stowed positions. Each guide 234 is configured to be included by an object holder 220(1), 220(2) or the seat bottom 200. The other of the object holder 220(1), 220(2) and the seat bottom 200 is configured to include a follower 236 configured to ride along the guide 234. FIGS. 25 to 28 show an embodiment in which each guide 234 is included in the seat bottom 200 at a location below a corresponding object holder 220(1), 220(2), and each object holder 220(1), 220(2) includes a follower 236 configured to ride along the guide 234. In this embodiment, each guide 234 includes an internal track, such as a slot, and each follower 236 includes a protrusion received in and rides along the internal track. The protrusion of the follower 236 includes a pair of opposing spring fingers. In some other embodiments, each guide includes an external track, such as a T-track, and the follower includes a recess that receives the external track. Further, in some other embodiments, each guide is configured to be implemented by an object holder and each follower is configured to be implemented by the seat bottom 200.

    [0117] In some embodiments, each guide 234 is configured to selectively lock one of the object holders 220(1), 220(2) in the extended and stowed positions. The guide 234 has a first enlarged portion 234a that corresponds to the extended position, a second enlarged portion 234b that corresponds to the stowed position, and an intermediate portion 234c between the first and second enlarged portions 234a and 234b. The first and second enlarged portions 234a and 234b are spaced from one another along a direction DG, and the intermediate portion 234c includes a width along a direction perpendicular to the direction DG, less than a width of the first and second enlarged portions 234a and 234b along the direction DG. The follower 236 is configured to snap into the first and second enlarged portions 234a and 234b when moved to the extended and stowed positions, respectively. Although not shown, in some embodiments, each guide 234 has at least one intermediate position between the extended and stowed positions. For example, each guide 234 has at least one enlarged portion between the first and second enlarged portions 234a and 234b that corresponds to the at least one intermediate position.

    [0118] Each object holder 220(1), 220(2) is configured to be positioned in the extended position when used by a child. When in the extended position, the child can have more leg room, as the object holder 220(1), 220(2) protrudes further into the seating area when the object holder 220(1), 220(2) is in the stowed position than in the extended position. Each object holder 220(1), 220(2) is configured to be positioned in the stowed position to reduce the outer width of the child safety seat 1 along the third direction D.sub.3. This configuration is beneficial to limit the size of packaging, such as the size of a box, needed to store the child safety seat 1 for shipping. This configuration is also beneficial when more room is desired to position one or more child safety seats next to the child safety seat 1 in a seating row of a vehicle.

    [0119] Turning now to FIGS. 30 to 32, in some embodiments, each object holder 220(1), 220(2) is configured to be attached to the seat bottom 200 using a tether 238. Each object holder 220(1), 220(2) is configured to be transitioned between an unfixed position (e.g., FIGS. 30 and 32) and a use position (e.g., FIG. 31). In the unfixed position, the object holder 220(1), 220(2) is movable relative to the seat bottom 200, where motion of the object holder 220(1), 220(2) is constrained by the tether 238. In the use position, the object holder 220(1), 220(2) is positioned to be used by a child seated in the child safety seat 1. In some embodiments, in the use position, the object holder 220(1), 220(2) is configured to be positionally fixed relative to the seat bottom 200 such that movement of the seat bottom 200 causes a corresponding movement of the object holder 220(1), 220(2). In some embodiments, each object holder 220(1), 220(2) is configured to be positionally fixed to a corresponding sidewall 210(1), 210(2).

    [0120] Each tether 238 is a wire, string, plastic strip, or any other suitable tether. Each tether 238 has a first end 238a attached to the seat bottom 200, such as to one of the sidewalls 210(1), 210(2). Each tether 238 has a second end 238b attached to a corresponding object holder 220(1), 220(2). Each first end 238a is configured to be attached to one of the sidewalls 210(1), 210(2), such as to a front end of one of the sidewalls 210(1), 210(2). Each tether 238 is configured to be attached to the seat bottom 200 in any suitable manner. In some embodiments, the first end 238a of each tether 238 is configured to be received in an opening 210a in one of the sidewalls 210(1), 210(2), or otherwise attached thereto. The first end 238a of each tether 238 includes a tooth 238c configured to be received in the opening 210a of the seat bottom 200, and configured to create an interference with an inner surface of the seat bottom 200 to prevent the tooth 238c from being removed from the opening 210a. The tooth 238c is disposed closer to the first end 238a than the second end 238b.

    [0121] The child safety seat 1 includes a fastener configured to affix the object holder 220(1), 220(2) to the seat bottom 200 in the use position. The fastener can be any suitable fastener. FIGS. 30 to 32 show some embodiments in which the fastener is a locking tooth 238d disposed at the second end 238b adjacent a corresponding object holder 220(1), 220(2). The locking tooth 238d is configured to be received in an opening 210a of the seat bottom 200, and configured to create an interference with an inner surface of the seat bottom 200 to prevent the locking tooth 238d from being removed from the opening 210a. To transition an object holder 220(1), 220(2) to the use position, a corresponding tether 238 is received in an opening 210a of the seat bottom 200 until the locking tooth 238d is received in the opening 210a. A wall of the seat bottom 200 is then trapped between the locking tooth 238d and the object holder 220(1), 220(2). A distance between the locking tooth 238d and the object holder 220(1), 220(2) is configured to be substantially equal to a thickness of a wall of the seat bottom 200 that defines the opening 210a.
