`FORWARD AND REARWARD FACING
`CHILD SEAT WITH BELT TENSIONING
`MECHANISM FOR IMPROVED
`INSTALLATION
`
`TECHNICAL FIELD
`
`The present invention generally relates to the field of child
`safety seats, and more particularly, to a child safety seat that
`may be used in either a forward facing or rearward facing
`orientation and includes a tensioning mechanism for apply(cid:173)
`ing tension to a seat belt to more fully secure the child safety
`seat to a vehicle seat, thereby providing for easier installa(cid:173)
`tion of the child safety seat to the vehicle seat.
`
`BACKGROUND
`
`Child safety seating products are designed to protect
`children in vehicles from the effects of impacts or other
`sudden changes in motion ( e.g., sudden deceleration). Child
`safety seats, commonly referred to simply as child seats,
`may be used in a variety of vehicles with a variety of seating
`orientations. For example, it is often recommended for the
`youngest children to use rear-facing child seats for addi(cid:173)
`tional safety, while forward-facing seats can be used when
`the child reaches an appropriate size. It is important for a
`child seat to be properly secured to the vehicle seat to protect
`the occupant, particularly during an impact.
`
`SUMMARY
`
`Some child safety seats are secured to a vehicle seat with
`the seat belt of the vehicle. In such situations, securing the
`child seat may be awkward and difficult. Moreover, main(cid:173)
`taining a proper amount of tension in the seat belt can also
`be difficult. Indeed, an improper amount of tension is
`undesirable and may negatively affect the safety of the
`occupant secured within the child seat. It would be advan(cid:173)
`tageous to have an easy-to-use and secure child seat that may 40
`be used in either a forward-facing or rear-facing configura(cid:173)
`tion depending on the parents' needs.
`Example embodiments of the present invention include a
`child seat that may be secured to a vehicle seat in both a
`rear-facing and front-facing orientation. The child seat may 45
`define a seat base that may define a seat portion and a
`backrest portion. The seat base may be designed to receive
`a seat belt from a vehicle seat and secure the child seat to the
`vehicle seat in an untensioned configuration. The seat belt
`may secure the child seat to the vehicle seat by using a
`tensioning mechanism that is attached to the seat base. In
`some embodiments, the tensioning mechanism may be
`moved between a first position that is adjacent to the seat
`base and a second position that is displaced from the seat
`base. The second position of the tensioning mechanism may 55
`allow the seat belt to be received by the seat base, while the
`first position holds the belt in a tensioned configuration.
`Moving the tensioning mechanism from the second position
`to the first position may apply the tension to the belt. The
`child seat may be able to receive the belt and apply tension 60
`to it when the child seat is in either or both of a rear-facing
`and front-facing orientation.
`In some embodiments, the tensioning mechanism may
`rotate between the first and second positions. By receiving
`a substantially vertical force, the tensioning mechanism may 65
`rotate from the second position to the first position and apply
`tension to the belt.
`
`2
`In some embodiments, the seat base may define a first
`edge and a second edge. The first and second edges may be
`configured to receive the belt and thereby define a first belt
`path spanning the first and second edges. Additionally, each
`5 of the first and second edges may have an inlet and a
`retaining channel, such that each inlet channel may guide the
`belt into the respective retaining channel. In some embodi(cid:173)
`ments, the seat base may receive the belt so as to define the
`first belt path when the child seat is in the rear-facing
`10 orientation. The seat base may define a second belt path
`spanning the first and second edges when the child seat is in
`the front-facing configuration. In some embodiments, first
`belt path may be defined between the tensioning mechanism
`and the seat base at a position proximate an intermediate
`15 region of the seat portion. The second belt path may be
`defined between the tensioning mechanism and the seat base
`at a position proximate an intersection of the seat portion and
`backrest portion of the seat base.
`Additionally, in some embodiments, a force for moving
`20 the tensioning mechanism from the second position to the
`first position while the belt is in the first belt path is
`substantially similar to a force for moving the tensioning
`mechanism from the second position to the first position
`while the belt is in the second belt path. The resulting tension
`25 applied to the belt in the first belt path may be substantially
`similar to the resulting tension applied to the belt in the
`second belt path.
`the tensioning
`in some embodiments,
`Additionally,
`mechanism may comprise an engaging surface that is adja-
`30 cent a surface of the seat base when the tension mechanism
`is in the first position. A portion of the first belt path
`corresponding to the first and second edges may be posi(cid:173)
`tioned higher than a portion of the first belt path correspond(cid:173)
`ing to the engaging surface of the tensioning mechanism,
`35 such that a portion of the belt engaged by the engaging
`surface may be deflected substantially towards the seat base
`with respect to portions of the belt engaged by the first and
`second edges when the tensioning mechanism is in the first
`position.
`In some embodiments, the seat base may provide an open
`belt path, such that the seat base is configured to receive an
`edge of the belt when the tensioning mechanism is in the
`second position while the belt is in a buckled position with
`the vehicle seat.
`Additionally, in some embodiments, the child seat may
`comprise a harness defining a first harness portion and a
`second harness portion. The first harness portion and the
`second harness portion may each be configured to rotate
`with the tensioning mechanism between the first position
`50 and the second position, such that the harness may be
`displaced away from the first belt path when the tension
`mechanism is moved from the first position to the second
`position.
`In some embodiments, the seat base may define opposing
`side portions, where each side portion may comprise a lock
`receiving portion. The tensioning mechanism may further
`comprise a locking mechanism comprising two laterally(cid:173)
`opposing locking members configured to translate between
`an extended position and a retracted position. Each lock
`receiving portion may be configured to receive a respective
`locking member when the tensioning mechanism is in the
`first position and the locking members are in the extended
`position, thereby locking the tensioning mechanism in the
`first position. The locking members may also be configured
`to automatically translate to the extended position when the
`tensioning mechanism is rotated from the second position to
`the first position.

`In some embodiments, the belt may define a lap section
`and a shoulder section. The seat base may be configured to
`receive a portion of the lap section and a portion of the
`shoulder section of the belt in an untensioned state to secure
`the child seat to the vehicle seat in an untensioned configu-
`ration.
`In another example embodiment, a child seat may be
`configured to be secured to a vehicle seat. The child seat may
`comprise a seat base defining a seat portion and a backrest
`portion. The seat base may be configured to receive a belt of 10
`a vehicle seat in an untensioned state to secure the child seat
`to the vehicle seat in an untensioned configuration. The seat
`base may further define a first edge and a second edge. The
`seat base may be configured to receive the belt so as to define
`a belt path spanning the first and second edges. Additionally, 15
`each of the first and second edges may comprise an inlet
`channel and a retaining channel such that the belt path may
`extend from the retaining channel in the first edge to the
`retaining channel in the second edge. The inlet channels of
`the first and second edge may then guide the belt into the 20
`retaining channels.
`Some embodiments may include a tensioning mechanism
`attached to the backrest portion of the seat base. The
`tensioning mechanism may be rotatable between a first
`position substantially adjacent to the seat base and a second 25
`position displaced therefrom. Placing the tensioning mecha(cid:173)
`nism in the second position may allow the seat base to
`receive the belt, and the movement of the tensioning mecha(cid:173)
`nism from the second position to the first position may apply
`tension to the belt to secure the child seat to the vehicle seat 30
`in a tensioned configuration. The tensioning mechanism
`may be configured to rotate, in response to receiving a
`substantially vertical force, from the second position to the
`first position to apply tension to the belt to secure the child
`seat to the vehicle seat in a tensioned configuration. The belt 35
`path may be defined between the tensioning mechanism and
`the seat base at a position proximate the center of the seat
`portion, so as to position the child seat in a rear-facing
`orientation. Alternatively, the belt path may be defined
`between the tensioning mechanism and the seat base at a 40
`position proximate the intersection of the backrest portion
`and seat portions, so as to position the child seat in a
`front-facing orientation.
`The seat base may further define opposing side portions,
`each of which may comprise a lock receiving portion. The 45
`tensioning mechanism may further comprise a locking
`mechanism comprising two
`laterally-opposing
`locking
`members configured to translate between an extended posi(cid:173)
`tion and a retracted position. Each lock receiving portion
`may be configured to receive a respective locking member 50
`when the tensioning mechanism is in the first position and
`the locking members are in the extended position, thereby
`locking the tensioning mechanism in the first position. In
`some embodiments, the locking members may be configured
`to automatically translate to the extended position when the 55
`tensioning mechanism is rotated from the second position to
`the first position.
`In yet another example embodiment, a method may be
`defined for manufacturing a child seat configured to be
`secured to a vehicle seat in both a rear-facing orientation and 60
`a front-facing orientation. The method may comprise pro(cid:173)
`viding a seat base defining a seat portion and a backrest
`portion. In some embodiments of the method, the seat base
`may be configured to receive a belt of the vehicle seat in an
`untensioned state to secure the child seat to the vehicle seat 65
`in an untensioned configuration. The method may comprise
`attaching a tensioning mechanism to the seat base, and the
`
`4
`tensioning mechanism may be rotatable between a first
`position substantially adjacent to the seat base and a second
`position displaced therefrom. Placing the tensioning mecha(cid:173)
`nism in the second position may allow the seat base to
`receive the belt, and the movement of the tensioning mecha(cid:173)
`nism from the second position to the first position may apply
`tension to the belt to secure the child seat to the vehicle seat
`in a tensioned configuration. The seat base of the child seat
`may be configured to receive the belt in both a rear-facing
`and front-facing orientation. The seat base may define a first
`edge and a second edge. The seat base may be configured to
`receive the belt so as to define a first belt path spanning the
`first and second edges. Each of the first and second edges
`may further comprise an inlet channel and a retaining
`channel, and each inlet channel may be configured to guide
`a portion of the belt into the respective retaining channel.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`The present invention will now be described more fully
`hereinafter with reference to the accompanying drawings, in
`which some, but not all embodiments of the inventions are
`shown. Indeed, these inventions may be embodied in many
`different forms and should not be construed as limited to the
`embodiments set forth herein; rather, these embodiments are
`provided so that this disclosure will satisfy applicable legal
`requirements. The terms "first" and "second" are used for
`
`6
`reference purposes only and are not limiting. The disclosure
`of U.S. patent application Ser. No. 13/602,846 is incorpo(cid:173)
`rated herein by reference in its entirety.
`A child safety seat may be configured for installation in
`5 either a front-facing or rear-facing orientation with respect
`to the vehicle seat to accommodate children in the appro(cid:173)
`priate position based on the height and weight of a child,
`such as according to the guidelines and standards of the
`United States National Highway Transportation Safety
`10 Administration (NHTSA) and similar authorities in other
`countries.
`In order to protect an occupant, a child safety seat must be
`secured to a fixed location in a vehicle. The type of secure(cid:173)
`ment depends on the type of vehicle and may also depend on
`the standards for the particular region the vehicle is being
`operated in. For example, a child safety seat may be secured
`to a vehicle using a variety of methods, including using the
`seat belt of the vehicle seat or LATCH (Lower Anchors and
`Tethers for Children) attachments in the U.S.
`Proper installation and use of a child safety seat within a
`vehicle is necessary to achieve the maximum protection
`afforded by the seat. As noted above, some child safety seats
`are designed to secure to a vehicle seat using the seat belt of
`the vehicle seat. Often a seat belt can be positioned around
`25 the child seat and then fastened (e.g., latched, buckled, etc.)
`into a buckle attached to the vehicle to achieve secure
`attachment of the child seat to the vehicle. However, even
`when the seat belt is tightly fastened, slack in the seat belt
`may occur. Indeed, the seat belt may not be fully tensioned
`30 and the child seat may be loosely secured to the vehicle,
`which may be unsafe for an occupant. In some cases,
`multiple attempts to fully secure a child seat to a vehicle seat
`using a seat belt may be required. As such, installation of a
`child seat using a vehicle seat belt can be difficult and time
`consuming.
`Accordingly, some example embodiments of the present
`invention provide a tensioning mechanism for easy and
`intuitive securing of a child seat using a vehicle seat belt.
`The tensioning mechanism enables a user to easily apply
`40 tension to (e.g., remove slack from) a latched seat belt
`during installation of the child seat to the vehicle seat. This
`causes the child seat to become more fully secured to the
`vehicle seat (
