Description:
TECHNICAL FIELD 
       [0001]    The disclosed inventive concept relates generally to vehicle seats and safety systems. More particularly, the disclosed inventive concept relates to a method and system for concealing child safety seat anchors when not in use by the provision of one or more selectively removable inserts. 
       BACKGROUND OF THE INVENTION 
       [0002]    Various state and federal rules and guidelines specify that children of certain ages should be seated in Child Restraint Systems (CRS) or in a booster seat. For example, the National Highway Traffic Safety Administration recommends that children from birth to three years old be positioned in a rear-facing car seat, while children between the ages of one year to seven years be seated in a forward-facing car seat. Booster seats are recommended for children between the ages of four and 12 years. Age variations for these recommendations are due to such factors as height and weight for the individual child. 
         [0003]    As a consequence of such safety standards, today&#39;s vehicle includes CRS anchors strategically located on one or more of the vehicle&#39;s seats. Such anchors are typically positioned in such a way so as to minimize intrusion into the aesthetics of the vehicle interior. As a consequence, rear seat (or lower) CRS anchors are commonly difficult to directly see or access without applying force to compress or displace vehicle seat foam to expose anchors. Thus it can be difficult for consumers to access the anchors to install or remove child seats in the rear seat of a vehicle. The zone-driven location of the anchors in which the position sometimes may additionally be affected by both comfort and styling can lead to a small zone of acceptable anchor placement which is not necessarily ideal for consumer access. 
         [0004]    In addition, when anchors are recessed under or behind vehicle seat foam, more effort is needed by the consumer to install the CRS. For example, it can be difficult to attach and detach CRS web strap hooks that engage the anchors for tensioning the child seat to the vehicle seat, compared to an environment in which an anchorage is readily accessible, protruding from the vehicle seat foam or trim. It can be especially difficult to detach a tensioned anchor with limited finger clearance, visibility and a CRS tensioned close to the area of limited accessibility. 
         [0005]    Thus today&#39;s vehicle designers are challenged to enhance the ease of CRS installation which would, as a consequence, improve compliance with proper seat installation. The solution for improving accessibility to lower child restraint anchorages for parents without affecting seating comfort or anchor performance must be cost-efficient and simple while enhancing customer satisfaction. Importantly, such a solution must aid in overcoming the reality that many CRS are often incorrectly installed and positioned in vehicles. 
         [0006]    A simple and consumer-friendly solution to balancing the need for consumer access to CRS anchors with the need for maintaining a vehicle interior design that is free of unattractive functional elements is desired. 
       SUMMARY OF THE INVENTION 
       [0007]    The disclosed inventive concept provides a solution to the need for concealing CRS anchors while simultaneously making them readily accessible to the consumer. The inventive concept disclosed herein provides the use of concealing seat trim that can be removed, slid, or rotated to reveal the CRS anchor. Such a system fully satisfies the need to provide easy access to the CRS anchor while fully and aesthetically concealing the anchor when not in use. 
         [0008]    The disclosed inventive concept provides a small trimmed section of seat foam that is removable, slidable or rotatable to simply reveal the CRS anchor while also providing a substantial improvement in accessibility, finger and hand clearance to the in-zone, fixed position CRS anchor. The disclosed inventive concept reduces the complexity, installation and removal efforts experienced by the consumer. 
         [0009]    The concealing trim foam pieces of the disclosed inventive concept may be small and individual, one for each affected anchor, or may be a single insert that spans the distance between a pair or set of anchors. The size of the anchor concealing trim piece can vary based on anchor location and styling as well as on how much additional accessibility is desired. 
         [0010]    The anchor concealing trim pieces may be held in their concealing position in a number of ways. For example, the trim pieces may be secured to the seat by hook-and-loop fasteners in a pocket in the lower portion of the primary seatback or a rear portion of primary seat cushion. Alternatively, the trim pieces may be snapped or CRS web strap and clipped into position by a simple c-CRS web strap and clip, j-CRS web strap and clip, or other fastener that provides the same function for attachment to a retention member disposed within the seat foam or seat structure. For example, an existing rod or wire-like support member found within many rear seat cushions or seatback frame structures. If such a member is not already present, a relatively simple reshaping in the design phase could provide the needed access points. Alternatively, a small interfacing member could be inserted into the primary cushion foam mold and become a local attachment point to which the rotatable, removable or slidable anchor concealing trim piece could be positively located. 
         [0011]    It should also be noted the relationship could be reversed where a CRS web strap and clip-like feature is provided in the primary seat base or back cushion and an interfacing feature like a wire, rod or other feature providing the same function is molded into the secondary insert piece of foam or trim covering the anchorages. These principles could also be applied to top tether anchorages, in certain circumstances, if so desired. 
         [0012]    The disclosed inventive concept overcomes the problems of known arrangements. Particularly, use of the disclosed inventive concept requires no detectable impact on styling, function, comfort, appearance, interior spaciousness, vehicle weight or cost. No actuator or release mechanisms are required as the anchors remain in their fixed zone positions. By providing a system in which the anchors are simply revealed by movement of the anchor concealing trim piece, a wide range of possible visibility and accessibility enhancements are made to provide ease with which a consumer can attach or detach a CRS to vehicle anchors. Variations of the disclosed inventive concept include providing a mechanism for automated movement of the anchor concealing trim piece between its anchor-concealing position and its anchor-exposing position. 
         [0013]    Use of the disclosed inventive concept will improve consumer compliance with proper CRS attachment through ease of access to the CRS anchor, thus significantly reducing incorrect attachment to the anchor. The design, content, validation, misuse, and end-user complexity are all minimized by the disclosed inventive concept. Multiple optional considerations are described herein where existing vehicle seat hardware can provide dual functionality, providing interfacing surfaces to which the trim/foam segments shown can be attached or removed from. 
         [0014]    The above advantages and other advantages and features will be readily apparent from the following detailed description of the preferred embodiments when taken in connection with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0035]    In the following figures, the same reference numerals will be used to refer to the same components. In the following description, various operating parameters and components are described for different constructed embodiments. These specific parameters and components are included as examples and are not meant to be limiting. 
         [0036]    Referring to  FIG. 1 , a perspective view of a portion of a vehicle seat is shown and is generally illustrated as  10 . The vehicle seat  10  includes a seat back  12  and a seat base  14 . CRS anchors  16  and  16 ′ are shown generally positioned at the area where the seat back  12  and the seat base  14  meet, as illustrated. A greater or lesser number of CRS anchors may be provided as is known in the art. 
         [0037]    While  FIG. 1  illustrates known locations of CRS anchors, attachment areas vary from vehicle seat to vehicle seat. Non-limiting examples of anchor accessibility locations are illustrated in  FIGS. 2 through 5 . Referring to these figures, a perspective view of a portion of a vehicle seat is shown and is generally illustrated as  20 . The vehicle seat  20  includes a seat back  22  and a seat base  24 . 
         [0038]    In  FIG. 2 , access locations  26  and  26 ′ are illustrated in the lower portion of the seat back  22 . In this configuration, it is desired to position a anchor concealing trim piece over each of the access locations  26  and  26 ′. 
         [0039]    In  FIG. 3 , an elongated access location  28  is illustrated, also in the lower portion of the seat back  22 . In this configuration, it is desired to position a single, elongated anchor concealing trim piece over the entire access location  28 . 
         [0040]    In  FIG. 4 , access locations  30  and  30 ′ are illustrated in the rearward portion of the seat base  24 . In this configuration, it is desired to position a anchor concealing trim piece over each of the access locations  30  and  30 ′. 
         [0041]    In  FIG. 5 , an elongated access location  32  is illustrated, also in the rearward portion of the seat base  24 . In this configuration, it is desired to position a single, elongated anchor concealing trim piece over the entire access location  32 . 
         [0042]    The access locations shown in  FIGS. 2 through 5  are suggestive only and are not intended as being limiting. It is to be understood that other locations may exist in either or both of the vehicle seat back  22  or the vehicle seat base  24 . 
         [0043]    The disclosed inventive concept includes removable, slidable or rotatable anchor concealing trim pieces as will be described below. An advantage of the disclosed inventive concept is that it may be incorporated into existing vehicle seats with the least amount of modification, and thus the least amount of expense. For example, attachment of the anchor concealing trim piece to the vehicle seat may be made by using existing seat structures, as illustrated in  FIGS. 6 and 7 . 
         [0044]    Referring to  FIG. 6 , a vehicle seat  40  is generally illustrated having a seat back  42  and a seat base  44 . A wireframe rod, such as wireframe rod  46 , is conventionally provided in the seat back  42 . The wireframe rod  46  is separate from the cushion foam and is usable as an attachment point for the concealing trim piece. A pair of CRS anchors  48  and  48 ′ is provided. 
         [0045]    As the wireframe rod  46  (or some variation thereof) is conventionally provided as part of the vehicle seat  40 , the disclosed inventive concept avoids the need to add new content to achieve attachment. The wireframe rod  46  is conveniently and favorably located directly above the CRS anchors  48  and  48 ′. 
         [0046]    The provision of wireframe rods in the existing vehicle seat is not limited to the seat back of the vehicle seat. As illustrated in  FIG. 7 , the wireframe rod may also be provided in the seat base of the vehicle seat. Particularly, the underside of a seat base  50 . The seat base  50  typically includes a skeletal wireframe  52  that may be used for convenient attachment of the concealing trim piece. 
         [0047]    The concealing trim pieces of the disclosed inventive concept that may be used in conjunction with the seats are shown in various configurations and arrangements in  FIGS. 8 through 19 . The concealing trim pieces may be composed of a variety of materials, though conventional polyurethane foam is the material of choice. The heights, lengths, widths, depths and locations of the concealing trim piece can be varied to achieve the desired balance of anchor accessibility or visibility as well as styling and comfort. Thus the illustrated concealing trim pieces shown in  FIGS. 8 through 19  are intended as being suggestive only and are not intended as being limiting. 
         [0048]      FIGS. 8 and 9  disclose a first embodiment of the disclosed inventive concept. Referring to  FIG. 8 , a sectional view of a vehicle seat, generally illustrated as  60 , is shown. The vehicle seat  60  includes a seat back  62  and a seat base  64  attached to a seat frame  66 . CRS anchors, of which one, a CRS anchor  68 , is shown, are conventionally provided and are anchored to a portion of the vehicle such as, for example, the seat frame  66 . A CRS attachment element such as a web strap and clip  70  is provided for releasable attachment of the CRS (not shown) to the CRS anchor  68 . 
         [0049]    A concealing trim piece  72  is removably fitted into a trim piece pocket  74 . The trim piece pocket  74  may extend below the concealing trim piece  72  and above the CRS anchor  68 . The concealing trim piece  72  is releasably held in place by any of several releasable attachment structures, including, without limitation, first portions  76  and  76 ′ and second portions  78  and  78 ′ of a hook-and-loop fastening system. Other releasably attachable arrangements are possible. As a further variation of this and all embodiments of the disclosed inventive concept, the lower portion of the seat back  62  may have one or more openings that allow the consumer to have access to push out the concealing trim piece  72  if desired. 
         [0050]    In  FIG. 8 , the concealing trim piece  72  is shown in its concealing position fitted into the trim piece pocket  74  and held in place by the first portions  76  and  76 ′ and second portions  78  and  78 ′ of the hook-and-loop fastening system. Where the upper area of the outer surface of the concealing trim piece  72  meets the outer surface of the seat back  62  may be “shingled” for styling reasons, although this arrangement is not illustrated in  FIG. 8 or 9 . 
         [0051]    To reveal the CRS anchor  68 , the consumer removes the concealing trim piece  72  as illustrated in  FIG. 9  and attachment of the CRS web strap and clip  70  to the CRS anchor  68  is made. Concealment of the CRS anchor  68  may be achieved once the CRS web strap and clip  70  is released by the consumer from the CRS anchor  68  and the concealing trim piece  72  is returned to its concealing position as shown in  FIG. 8 . 
         [0052]      FIGS. 10 and 11  disclose a second embodiment of the disclosed inventive concept. This embodiment provides an alternative to the hook-and-loop fastening system of the first embodiment of the disclosed inventive concept shown in  FIGS. 8 and 9  and discussed in relation thereto. 
         [0053]    Referring to  FIG. 10 , a sectional view of a vehicle seat, generally illustrated as  80 , is shown. The vehicle seat  80  includes a seat back  82  and a seat base  84  attached to a seat frame  86 . CRS anchors, of which one, a CRS anchor  88 , is shown, are conventionally provided and are anchored to a portion of the vehicle such as, for example, the seat frame  86 . A CRS attachment element such as a CRS web strap and clip  90  is provided for releasable attachment of the CRS (not shown) to the CRS anchor  88 . 
         [0054]    The concealing trim piece  92  is releasably held in place by the releasable interconnection of the concealing trim piece  92  to a pair of transverse rods  94  and  94 ′ that are either locally embedded in the seat foam of the seat back  82  or are part of the skeleton of the vehicle seat. It is to be understood that while two transverse rods  94  and  94 ′ are shown, a greater or lesser number of transverse rods may be used. A trim piece pocket  96  is formed in the lower portion of the seat back  82 . 
         [0055]    As illustrated in  FIG. 11 , a pair of spaced apart channels  98  and  98 ′ are formed in the back side of the concealing trim piece  92 . Accordingly, the transverse rods  94  and  94 ′ are releasably locked into the pair of spaced apart channels  98  and  98 ′ to thereby hold the concealing trim piece  92  in the trim piece pocket  96 . It is to be understood that while the rods  94  and  94 ′ are illustrated as being transverse, it is possible that the rods could also be oriented vertically. 
         [0056]    While in  FIG. 10  the concealing trim piece  92  is shown in its concealing position fitted into the trim piece pocket  96  and held in place by the locking interrelationship of the transverse rods  94  and  94 ′ with the channels  98  and  98 ′ having embedded clips (such as C-clips made from a plastic or a metal), to reveal the CRS anchor  88 , the consumer removes the concealing trim piece  92  as illustrated in  FIG. 11 . With the concealing trim piece  92  thus removed, attachment of the CRS web strap and clip  90  to the CRS anchor  88  may be made. Concealment of the CRS anchor  88  may once again be achieved after the CRS web strap and clip  90  is released by the consumer from the CRS anchor  88  and the concealing trim piece  92  is returned to its concealing position as shown in  FIG. 10 . 
         [0057]    A variation of the second embodiment of the disclosed inventive concept is illustrated in  FIG. 12  in which the concealing trim piece  92  has a release tab  100 . The release tab  100  may include the requisite ISO and may be a cloth tag sewn into concealing trim piece  92  of the type that may be found on various vehicle seats. The release tab  100  may be attached to the concealing trim piece  92  to both identify anchor location and to provide a surface to grab onto to remove the concealing trim piece  92 . 
         [0058]    The disclosed inventive concept may have further variations related to removability of the concealing trim piece versus rotatability or movability of the concealing trim piece. Particularly, the embodiments shown in  FIGS. 14 through 19  provide alternatives to the need for the consumer to remove and store the concealing trim piece as is the case in the embodiments shown in  FIGS. 8 through 13 . 
         [0059]    Referring to  FIGS. 14 through 16 , a third embodiment of the disclosed inventive concept is illustrated. Referring to  FIG. 14 , a sectional view of a vehicle seat, generally illustrated as  110 , is shown. The vehicle seat  110  includes a seat back  112  and a seat base  114  attached to a seat frame  116 . CRS anchors, of which one, a CRS anchor  118 , is shown, are conventionally provided and are anchored to a portion of the vehicle such as, for example, the seat frame  116 . A CRS attachment element such as a web strap and clip  120  is provided for releasable attachment of the CRS (not shown) to the CRS anchor  118 . 
         [0060]    A rotatable concealing trim piece  122  is rotatably fitted in a trim piece pocket  124 . The trim piece pocket  124  may extend below the rotatable concealing trim piece  122  and above the CRS anchor  118 . The rotatable concealing trim piece  122  is rotatably mounted on a transverse rod  128  that is fitted into a channel  128  formed in the rotatable concealing trim piece  122 . The channel  128  may be defined by a C-clip or other retention element. The C-clip-lined channel  128  is shown in close-up in  FIG. 15 . A release tab  130  is preferably attached to the rotatable concealing trim piece  122 . 
         [0061]    In  FIG. 14 , the rotatable concealing trim piece  122  is shown in its concealing position rotated to its concealing position in the trim piece pocket  124  such that the CRS anchor  118  is concealed. To reveal the CRS anchor  118 , the consumer rotates the rotatable concealing trim piece  122  as illustrated in  FIG. 16  and attachment of the CRS web strap and clip  120  to the CRS anchor  118  is made. Concealment of the CRS anchor  118  may be achieved once the CRS web strap and clip  120  is released by the consumer from the CRS anchor  118  and the rotatable concealing trim piece  122  is rotated back to its concealing position as shown in  FIG. 14 . 
         [0062]    A variation of the third embodiment of the disclosed inventive concept illustrated in  FIGS. 14 through 16  and discussed in relation thereto is a fourth embodiment of the disclosed inventive concept illustrated in  FIG. 17 . Referring thereto, a sectional view of a vehicle seat, generally illustrated as  140 , is shown. The vehicle seat  140  includes a seat back  142  and a seat base  144  attached to a seat frame  146 . CRS anchors, of which one, a CRS anchor  148 , is shown, are conventionally provided and are anchored to a portion of the vehicle such as, for example, the seat frame  146 . A CRS attachment element such as a web strap and clip  150  is provided for releasable attachment of the CRS (not shown) to the CRS anchor  148 . 
         [0063]    A rotatable concealing trim piece  152  is rotatably fitted in a trim piece pocket  154 . The rotatable concealing trim piece  152  is rotatably mounted on a transverse rod  156  that is fitted into a channel  158  formed in the rotatable concealing trim piece  152 . The channel  158  may be defined by a C-clip or other retention element. 
         [0064]    The fourth embodiment of the disclosed inventive concept differs from the third embodiment in that a positive stop is provided to prevent unintended rotation of the rotatable concealing trim piece  152  about the transverse rod  156 . The positive stop is provided in the form of a second transverse rode  160  against which the rotatable concealing trim piece  152  rests when in its concealing position as illustrated in  FIG. 17 . 
         [0065]    A fifth embodiment of the disclosed inventive concept is illustrated in  FIGS. 18 and 19 . Like the third and fourth embodiments discussed above in relation to  FIGS. 14 through 17 , the fifth embodiment requires only movement and not removal of the concealing trim piece to reveal the CRS anchor. 
         [0066]    Referring to  FIG. 18 , a sectional view of a vehicle seat, generally illustrated as  170 , is shown. The vehicle seat  170  includes a seat back  172  and a seat base  174  attached to a seat frame  176 . CRS anchors, of which one, a CRS anchor  178 , is shown, are conventionally provided and are anchored to a portion of the vehicle such as, for example, the seat frame  176 .

The slidable trim piece pocket  184  may be of any shape including the shape illustrated. The slidable trim piece pocket  184 , which may be a friction contact path, allows the slidable concealing trim piece  182  to be moved upwards into the seat back  172 . 
         [0068]    In addition, a rearward-positioned portion of the seat base  174  may be movable to allow greater access to the CRS anchor  178 . This portion, a rotating concealing trim piece  186 , rotates on an optional pivot rod  188 . An attachment rod  190  is provided. A C-clip  192  is preferably fitted to the rotating concealing trim piece  186 . In their concealing positions as illustrated in  FIG. 18 , the slidable concealing trim piece  182  is moved downward and the rotating concealing trim piece  186  remains in its raised position. 
         [0069]    If the consumer desires to have access to the CRS anchor  178 , the slidable concealing trim piece  182  is moved upward into the seat back  172  and the rotating concealing trim piece  186  is rotated downward until the attachment rod  190  locks into the C-clip  192  as illustrated in  FIG. 19 . 
         [0070]    The system for concealing a CRS anchor according to the disclosed inventive concept may be employed in any vehicle seat conventionally fitted with a CRS anchor. While specific locations of the CRS anchor have been illustrated in the figures and described in relation thereto, it is to be understood that the CRS anchors may be provided in locations other than those shown and described. However, the concealing trim piece of the disclosed inventive concept would find application regardless of the location of the CRS anchors. 
         [0071]    One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims that various changes, modifications and variations can be made therein without departing from the true spirit and fair scope of the invention as defined by the following claims.
