DETAILED DESCRIPTION
(18) The subject innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It may be evident, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the present invention.

(22) Moreover, in an embodiment, the base 30 can include an adjustable member, such as, an angle-adjusting foot 140 that can compensate for variations in the shape of vehicle seats. The angle-adjusting foot 140 can be raised or lowered from a bottom surface 400 of the base 30. To adjust the angle and fit between the base 30 and a vehicle seat, the angle-adjusting foot 140 can be raised or lowered to one of multiple positions 142, and secured in a selected position 142 via a locking member 402. The locking member 402 can be actuated by a lever 23 (See
(23) Referring to
(24) In an embodiment, the tension arm 100 can be pivotally connected to the base 30, such that the tension arm 100 can be pivotally raised and lowered in and out of the base 30. The tension arm 100 can be configured to clamp the LATCH belt 40 (or vehicle belt 42) into the belt path 120 of the base 30, which tensions the LATCH belt 40 to secure the base 30 to a vehicle seat. During installation of the base 30 onto a vehicle seat, the tension arm 100 is raised upwards to expose the belt path 120. A vehicle belt 42 (or LATCH belt 40) can then be passed through the belt guides 50, 60 and across the belt path 120 and buckled to the vehicle seat. Once any slack in the vehicle belt 42 is removed, the tension arm 100 can be lowered into the base 30 and clamped down on the vehicle belt 42. This action forces the vehicle belt 42 into the belt path 120 in a convoluted configuration (i.e., from the vehicle seat, over the belt guide 50, under the tension arm 100, over the other belt guide 60, and back down to the vehicle seat) that tensions the base 30 into the vehicle seat. This action also retracts the tensioned vehicle belt 42 into the belt path 120, so that there is sufficient access for the carrier 20 to be installed into the base. In other words, the vehicle belt 42 is retracted and retained so that it does not obstruct the alignment and installation of the carrier to base.

(28) As the weight of the car seat 10, and potentially that of a child, bear down on an end of the vehicle seat 704, a downward force 712 and rotational force 710 may be forcing the base 30 to bend over the end of the vehicle seat 704. Some prior art car seat bases overcome this by using high sidewalls on the base and location of the latch points connecting the carrier to the car seat base.
(29) In contrast, in an embodiment, base 30 can include an internal frame of steel tubes for additional support. The tension arm 100 can also be made of steel and can resist the forces 710, 712 to prevent the base 30 from bending over the end of the vehicle seat 704. This configuration allows for the base 30 to have a low profile. The steel structure may also assist in transferring the forces from the front of the base (i.e., area being forced to bend over the end of vehicle seat 704) to the area where the LATCH belt 40 or vehicle belt 42 attaches the base 30 to the vehicle seat which may relieve stress in plastic parts of the base 30.
(30) In partial summary, in various embodiments, the present invention provides a rear-facing or forward-facing car seat 10 that can include a carrier portion 20 in which an infant or child can be harnessed in, and a base portion 30 that can be fastened to a vehicle seat with a vehicle belt 42 or a LATCH belt 40. The carrier portion 20 can be releasably attached to the base 30, allowing the carrier 20 and child to be removed from the vehicle without uninstalling the base 30. The base 30 has a bottom surface 400 that can be contoured in such a way as to bridge the vehicle seat bight and contact both the seat portion and backrest portion of the vehicle seat. This improves the installation of the base 30 and allows for variation in the shape of the vehicle seat. The base 30 can further include a belt tensioning device (i.e., tension arm 100) that can be used to tension the vehicle belt 42 or the LATCH belt 40, thereby securing and tensioning the base 30 onto the vehicle seat. The belt tensioning device enables the LATCH belt 40 or vehicle belt 42 to be easily routed across the base 30, and allows a user to tension the belt 40, 42 with minimal force.

(33) The detachable crotch belt 800 can include a strap 802 that can have a clip 804 on one end of the strap 802, and a buckle 803 or other fastener on the other end. The clip 804 can be used to attach the crotch belt 800 to the carrier 20 via one or more of the slots 805, 806. The buckle 803 can be used to releasably attach the crotch belt 800 to the harness 900.
(34) The position of the crotch belt 800 can be adjusted by connecting the belt 800 through one or more of the slots 805, 806. As shown in
(35) The length of the crotch belt 800 can be adjusted by passing the end of the strap 802 having the clip 804 through multiple slots 805, 806 and securing the clip on a selected slot. For example, as shown in

(37) Generally, the chest clip 1000 is a buckle device that can be used to position the harness 900 correctly on a child's chest so that in the event of a crash or other accident, the harness 900 can correctly restrain the child. The chest clip 1000 is not a crash device, but only a pre-crash positioner. The chest clip 1000, in an embodiment, can be threaded onto the harness 900 above the harness buckle, and positioned at the armpit level of the child. This configuration holds the harness webbing in a correct position over the child's chest. Chest clips come in varying sizes to be used with differing sizes of children.
(38) The chest clip 1000 can be sized appropriately for use with infants and children. Because the chest clip is a pre-crash positioner, it is important that it is positioned correctly, and that it cannot be disengaged or opened by the child while seated in the car seat 10. If the child opened the chest clip, the child could potentially pull the harness 900 down off its shoulders and compromise the safety function of the harness 900 in a vehicle crash or accident.
(39) The configuration of chest clip 1000 makes it difficult for a child to disengage and open the chest clip, due to the two interlocking portions 1002, 1006 having separate respective actuators 1004, 1008, which must be simultaneously selected to disengage and unlock the chest clip 1000. A young child may have difficulty figuring out that release requires pushing both buttons 1004, 1008 on the chest clip 1000 at the same time making unintended release less likely. In addition, even if the child figured out the solution, a young child may not have the strength or manual dexterity to accomplish the task.

(41) Carriers can be held and carried in a variety of ways. For example, some people grasp the top of the handle and carry the carrier like a bucket. Others place their arm under the handle and carry the carrier in the crook of their elbow. Utilizing the grip feature 1110 described above, the carrier 20 can also be carried by weaving an arm around the handle 12 and grasping the hub 1102 closest to the user, and curling one's fingers around the grip feature 1110. An advantage of the grip feature 1110 is that it makes carrying the carrier 20 easier, and prevents a user's hand from slipping off the hub 1102.
(42) Moreover, when holding the carrier 20 this way, a user's arm is extended straight down and the carrier 20 can be held close to a user's body near the hip. As shown in
(43)
(44) In general, to move the carry handle 12 of a car seat to various positions, both release buttons 1103 on the handle hubs 1102 need to be pressed. An exception is the laidback position that for purposes of parental convenience does not lock in place like the other available positions. In an embodiment, the handle 12 can be configured to move from the laidback position to a carry position without requiring the pressing of release buttons 1103 on the handle hubs 1102. This is a convenience feature for parents because it allows for singlehanded operation. For example, a parent may place the handle 12 in the laid back position (
(45) Referring to
(46) The handle latching mechanism 1300 can be housed in the hubs 1102, and coupled to the handle 12. The handle latching mechanism 1300 can enable the handle 12 to be moved or rotated to a selected position from multiple available positions. In an embodiment, there can be four possible positions that the handle 12 can be moved to. The handle latching mechanism 1300 can be configured to lock the handle 12 in a particular position. In an embodiment, the handle 12 and latching mechanism 1300 can be configured so that the handle 12 movement ratchets from position to position.

(54) In summary, the car seat shown includes two doors 1402 that pivot inward exposing a surface 1403 for a hook to catch on. The doors serve the purpose of closing off a hole when the attachment is not being used, and they also are the means by which the hook is pushed off the catch to release the car seat from a stroller. The doors are spring loaded to the closed position. Internally the doors are connected to the release handle on the back shell of the carrier 20. This is the same handle used to release the carrier 20 from the base 30. The stroller can have a post feature that extends into a receptacle behind the handle hub, and can also have a hook that is spring loaded to the extended position. When a car seat is lowered onto the posts of the stroller, the hooks on the posts push the doors 1402 open and catch on the shell of the carrier 20 so that the carrier cannot be released until the release handle 22 on the back of the carrier 20 is actuated. The spring loaded hook on the post is not connected mechanically to any actuator. It is only actuated by the carrier door 1402 when the release handle 22 on the carrier is actuated.
(55) Moreover, in an embodiment, the stroller to car seat interaction described above can be used in connection with modular type strollers, in which the child seat of the stroller is removed and the car seat 20 is attached. In other embodiments, the carrier 20 can be positioned into the child seat of the stroller. In such a configuration, the internal surface of the stroller child seat can have hooks (that may be covered by fabric but could be revealed for travel system use), which can engage in the same area (i.e., surface 1403) on the carrier 20 as the hooks on the stroller post.
