DETAILED DESCRIPTION OF THE DRAWINGS
It will be apparent to those skilled in the art that many uses and design variations are possible for the child seat disclosed herein. The following detailed discussion of various alternative and preferred embodiments will illustrate the general principles of the invention. Other embodiments will be apparent to those skilled in the art given the benefit of this disclosure.
FIGS. 1 through 14 illustrate various embodiments of the present invention. A primary aspect of this invention shown in the figures is for a child seat. The term “child” includes a baby, an infant, and a child. The terminology “child seat” includes, without limitation, child seats for use in vehicles which use a vehicle lap and/or shoulder belt to secure the child seat to the vehicle and which have a separate child harness to secure the child in the child seat, child seats (sometimes called booster seats because they raise a child to a proper seating height for the vehicle shoulder belts) which use the vehicle lap and shoulder belts to secure the child in the child seat and secure the child seat to the vehicle, and child seats which can be used with a separate child harness when the child is younger and which can be used without a separate child harness when the child is older. The terminology “child seat” includes forward and rearward facing child seats. Additionally, as used herein, child seat may refer to other types of seats designed for seating children including high chair seats and stroller seats.
FIGS. 1 through 5 depict one embodiment of the present invention. Specifically, these figures show various views of the child seat with adjustable headrest unit. Generally, the adjustable headrest unit includes a headrest section 10 having a base member 12, a backrest section 14 having a receiving channel 16 adapted to receive the base member 12, a plurality of channel teeth 18 coupled to the receiving channel 16, and an adjustment lever 20 pivotally coupled to the base member 12 at a pivot point 22, the adjustment lever 20 having a trigger end 24 and a locking flange end 26. The base member 12 can be inserted into the receiving channel 16 to couple the headrest section 10 to the backrest section 14. Upon inserting the base member 12 into the receiving channel 16, the locking flange end 26 of the adjustment lever 20 may be engaged to the channel teeth 18 such that the base member 12 can no longer move toward or away from the backrest section 14.
This aspect of this embodiment of the present invention may be adjusted by utilizing the adjustment lever 20. When the base member 12 is received by the receiving channel 16, the locking flange end 26 of the adjustment lever 20 is typically biased toward the channel teeth 18. This bias may be the result of a spring or bias flange providing forces on the adjustment lever 20. Such forces result in the locking flange end 26 tending to engage the channel teeth 18, thus statically locking the base member 12 with the receiving channel 16. Disengaging the trigger end 24 causes the adjustment lever 20 to pivot about the pivot point 22 and simultaneously causes the locking flange end 26 to engage at least one of the plurality of channel teeth 18, thereby restricting a user from adjusting the headrest section 10 relative to and in the same plane as the backrest section 14. Furthermore, engaging the trigger end 24 causes the adjustment lever 20 to pivot about the pivot point 22 and simultaneously causes the locking flange end 26 to disengage from the plurality of channel teeth 18, thereby allowing a user to adjust the headrest section 10 relative to and in the same plane as the backrest section 14.
This embodiment may be adapted such that the locking flange end 26 may engage the one of a plurality of channel teeth 18. By doing this, the headrest section 10 may be moved to various distances relative to the backrest section 14. When a user places the headrest section 10 in the desired position relative to the backrest section 14, the locking flange end 26 may engage the corresponding channel tooth 18 to restrict further travel between the headrest section 10 and the backrest section 14.
This first embodiment may also include a safety belt guide 30 coupled to the headrest section 10, the safety belt guide 30 adapted to receive an automobile safety belt for securing the child seat to an automobile seat. This safety belt guide 30 will typically (but not limited to) receive a shoulder belt of an automobile safety belt. In one example, a shoulder belt of an automotive safety belt will travel from the point of attachment in the automobile, through the safety belt guide 30, over a shoulder of a child seated in the child seat, and attach to the safety belt receiver in the automobile. In another example, the shoulder belt of the safety belt may not be utilized to secure the child. Further, a child or other user of the present invention may utilize the light source 32 within the safety belt guide 30. Such a light source 32 may be a light emitting diode (LED) powered by at least one battery. This light source 32 may also have a switch 34 designed to allow or restrict the light source 32 from providing light. This switch 34 may be a button, a toggle, or a trigger. Other types of switches may also be utilized.
It is further of note that the headrest section 10, the backrest section 14, and the adjustment lever 20 may be made from at least one plastic or composite such as polypropylene. This also includes any other plastic or composite material known in the art.
Another aspect of a first embodiment includes a softgoods attachment 36 removably coupled to the headrest section 10. This softgoods attachment 36 may be made of foam, such as a polystyrene foam, polyurethane foam, or polyethylene foam. In one example, this may include Styrofoam© brand name foam. Alternatively, it may be made of padding or fabric or any other material considered soft or comfortable for receiving a child. Another aspect of this embodiment includes a fabric covering 38 permanently or removably coupled to the softgoods attachment 36. This fabric covering 38 may be made from synthetic or natural fabrics including cotton materials. This fabric covering 38 may be coupled to the softgoods attachment 36 by means of glue, epoxy, Velcro© attachment, elastic material, or any other attachment materials known in the art. Alternatively, the fabric may be opened to cover the softgoods attachment using a zipper or the like. Such fabric covering 38 may also include a padding material.

Generally, the adjustable backrest unit includes a lower backrest section 40, an upper backrest section 42 having a receiving channel 44 adapted to receive the lower backrest section 40, a plurality of receiving notches 46 coupled to the lower backrest section 40, and an adjustment lever 50 pivotally coupled to the upper backrest section at a pivot point 42, the adjustment lever 50 having a trigger end 54 and a locking flange end 56. The lower backrest section 40 can be inserted into the receiving channel 44 to couple the lower backrest section 40 to the upper backrest section 42. Upon inserting the lower backrest section 40 into the receiving channel 44, the locking flange end 56 of the adjustment lever 50 may be engaged to the receiving notches 46 such that the lower backrest section 40 can no longer move toward or away from the upper backrest section 42.
This aspect of this embodiment of the present invention may be adjusted by utilizing the adjustment lever 50. When the lower backrest section 40 is received by the receiving channel 44, the locking flange end 56 of the adjustment lever 50 is typically biased toward the receiving notches 46. This bias may be the result of a spring or bias flange providing forces on the adjustment lever 50. Such forces result in the locking flange end 56 tending to engage the receiving notches 46, thus statically locking the lower backrest section 40 with the receiving channel 44. Engaging the trigger end 54 causes the adjustment lever 50 to pivot about the pivot point 52 and simultaneously causes the locking flange end 56 to disengage from the plurality of receiving notches 46, thereby allowing a user to adjust the upper backrest section 42 relative to and in the same plane as the lower backrest section 40. Further, disengaging the trigger end 54 causes the adjustment lever 50 to pivot about the pivot point 52 and simultaneously causes the locking flange end 56 to engage at least one of the plurality of receiving notches 46, thereby restricting a user from adjusting the upper backrest section 42 relative to and in the same plane as the lower backrest section 40.
This embodiment may be adapted such that the locking flange end 56 may engage the one of a plurality of receiving notches 46. By doing this, the upper backrest section 42 may be moved to various distances relative to the lower backrest section 40. When a user places the upper backrest section 42 in the desired position relative to the lower backrest section 40, the locking flange end 56 may engage the corresponding receiving notch 46 to restrict further travel between the upper backrest section 42 and the lower backrest section 40.
It is further of note that the upper backrest section 42, the lower backrest section 40, and the adjustment lever 50 may be made from at least one plastic or composite such as polypropylene. This also includes any other plastic or composite material known in the art.
Another aspect of this embodiment includes a softgoods attachment 36 removably coupled to the upper backrest section 42. This softgoods attachment 36 may be made of foam, such as a polystyrene foam, polyurethane foam, or polyethylene foam. In one example, this may include Styrofoam© brand name foam. Alternatively, it may be made of padding or fabric or any other material considered soft or comfortable for receiving a child. Another aspect of this embodiment includes a fabric covering 38 permanently or removably coupled to the softgoods attachment 36. This fabric covering 38 may be made from synthetic or natural fabrics including cotton materials. This fabric covering 38 may be coupled to the softgoods attachment 36 by means of glue, epoxy, Velcro© attachment, elastic material, or any other attachment materials known in the art. Alternatively, the fabric may be opened to cover the softgoods attachment using a zipper or the like. Such fabric covering 38 may also include a padding material.
In yet another aspect of this embodiment, the lower backrest section 40 is removably coupled to the seatrest section 48. In view of this aspect, a child can sit on the seatrest section 48 while having back support from the combination of the lower 40 and upper backrest sections 42.
FIG. 10 shows another embodiment of the present invention. Specifically, FIG. 10 depicts a view of the seatrest unit including the adjustable armrest unit and the coupling mechanism 94 of the adjustable lap depth. Generally, the adjustable armrest unit includes an armrest member 58, an adjustment lever 60 pivotally coupled to the armrest member 58 at a pivot point 62, the adjustment lever 60 having a trigger end 64 and a locking flange end 66, a seatrest section 68 having a side portion 70, a receiving channel 72, coupled to the side portion 70 of the seatrest section 68, adapted to receive the armrest member 58, and at least one receiving notch 74 coupled to the receiving channel 72.
This aspect of this embodiment of the present invention may be adjusted by utilizing the adjustment lever 60. When the armrest member 58 is received by the receiving channel 72, the locking flange end 66 of the adjustment lever 60 is typically biased toward the receiving notches 74. This bias may be the result of a spring or bias flange providing forces on the adjustment lever 60. Such forces result in the locking flange end 66 tending to engage the receiving notch 74, thus statically locking the armrest member 58 with the receiving channel 72. Engaging the trigger end 64 causes the adjustment lever 60 to pivot about the pivot point 62 and simultaneously causes the locking flange end 66 to disengage from the at least one receiving notch 74, thereby allowing a user to adjust the armrest member 58 relative to and in the same plane as the side portion 70 of the seatrest section 68. Further, disengaging the trigger end 64 causes the adjustment lever 60 to pivot about the pivot point 62 and simultaneously causes the locking flange end 66 to engage the at least one receiving notch 74, thereby restricting a user from adjusting the armrest member 58 relative to and in the same plane as the side portion 70 of the seatrest section 68.
It is further of note that the armrest member 58, the seatrest section 68, and the adjustment lever 60 may be made from at least one plastic or composite such as polypropylene. This also includes any other plastic or composite material known in the art.
FIGS. 11 and 12 specifically depict examples of the softgoods attachment 36, 78 found in the various embodiments of the present invention, as described throughout this disclosure. Note that the softgoods attachment 36, 78 is also depicted in the other figures.
Generally, the child seat with softgoods attachment includes a child seat shell 76, a softgoods attachment 78, and at least one connector 80 coupled to the softgoods attachment 78, the at least one connector 80 having a base end 82 and a threaded end 84 such that the base end 82 has a larger diameter than the threaded end 84. The softgoods attachment 78 includes at least one softgoods opening 86 adapted to allow the threaded end 84 of at least one connector 80 to pass through the softgoods attachment 78, while restricting the base end 82 of the at least one connector 80. Further, the child seat shell 76 includes at least one shell opening 88 adapted to receive the threaded end 84 of the at least one connector 80. The softgoods attachment 78 is removably coupled to the child seat shell 76 by means of the at least one connector 80 without engaging or covering any of the edges, corners, or outer portions of the seat shell.
It is of note that the child seat shell 76 and at least one connector 80 may be made from at least one plastic or composite such as polypropylene. This also includes any other plastic or composite material known in the art.
This softgoods attachment 78 may be made of foam, such as a polystyrene foam, polyurethane foam, or polyethylene foam. In one example, this may include Styrofoam© brand name foam. Another aspect of this embodiment includes a fabric covering 38 permanently or removably coupled to the softgoods attachment 78. This fabric covering 38 may be made from synthetic or natural fabrics including cotton materials. This fabric covering 38 may be coupled to the softgoods attachment 78 by means of glue, epoxy, Velcro© attachment, elastic material, or any other attachment materials known in the art. Such fabric covering 38 may also include a padding material.
The connector 80 provides a means of easily attaching softgoods 78 to a child seat shell 76. While a threaded connector 80 is specifically disclosed herein, any other connector which operates to specifically anchor and hold the soft goods attachment 78 directly to the seat to provide a clean look without hooking over or around the edges of the seat shell would be operative and are considered within the scope of the invention. When a user wishes to connect the softgoods attachment 78 to the child seat 76, she may place the softgoods attachment 78 proximate a child seat shell 76, aligning the at least one connector 80 coupled to the softgoods attachment 78 with at least one shell opening 88 of the child seat shell 76. Next the user can easily screw the at least one connector 80 until the at least one connector 80 engages the at least one shell opening 88. The user should continue tightening the at least one connector 80 until screwing of the at least one connector 80 and the at least one shell opening 88 can no longer occur. The twisting action may be done in a clockwise or counter-clockwise manner. The result may be tightening or loosening of the softgoods attachment 78 from the child seat shell 76, depending on the connector 80 design.
In any of the embodiments, softgoods attachments 78 may be coupled to various sections or members of the child seat 76 or child seat shell 76. This coupling provides comfort to a child using said child seat 76.
FIGS. 13 and 14 depict another embodiment of the present invention. Specifically, these figures show various views of the child seat with adjustable lap depth.
