Description

INTEGRATED SEAT FOR CHILDREN WITH RETRACTOR ASSEMBLY OF PERSONAL SECURITY Atü i PRNT f? PE THE INVENTION This invention relates to vehicle seats, and more particularly to integrated seats for motor vehicles capable of moving between an adult position and a child position. The integrated seats which contemplate both the child and adult position must contrast with the practice in which the seats provided are adult seats, and the separate child seat units are used to house children. The usual situation is one in which separate units of each contain their own seating belt or occupant immobilizer assemblies and the separate children's unit is fixed to the existing adult seat by attaching the separate child unit to the adult seat. by mounting safety belt for adult. The integrated seats are provided with a movable mattress construction, which can be moved between an adult position and a child position. In the adult position, the mobile mattress construction is usually folded so that the integrated seat REF: 23192 in its entirety provides an adult seat and an adult seat backrest. In most of the arrangements, when in adult position, the mobile mattress construction is part of the adult seat backrest, although in other arrangements the mobile mattress construction is part of the adult seat. In the children's position, the mobile mattress construction is unfolded and arranged to provide a cushioned or cushioned child seat in superposed relation to the adult seat. Integrated seats are also usually provided with either an adult seat belt assembly or a child seat belt assembly. When the integrated seat is in adult position, the child seat belt assembly is usually folded into the backrest of the adult seat with the mobile mattress construction. An advance in integrated seating is described in U.S. Patent No. 5,225,756 ("the '756 patent"). So far, the integrated seats have been mainly provided with two different types of mounting tension fixings for child safety belt. The first type uses a tension adjuster in which a portion of the belt or band is retained in a clamped manner between a transverse member and a serrated surface, as described in the '756 patent mentioned in the foregoing. The second type incorporates a retractor assembly having a deviated winding coil, which is normally deflected to wind the belt material so that a desired tension is obtained in the belt. Each of the arrangements mentioned in the above obtains its benefits and particular applications. Heretofore, deviated coiled coils provide child safety belt assemblies that are mounted on the lower portions of the seat frame assembly or on the lower portions of the child seat module. For example, U.S. Patent No. 5,280,995 to Elton ("the '995 patent") discloses a vehicle seat mount having a child seat integrated with a dual retractor assembly mounted on a bracket placed at the bottom of the panel rear of the child seat, adjacent to the floor of the vehicle. Providing retractor mounts or winding coils in such a position requires that the two shoulder belts of the child safety belt assembly extend from above from the coils and onto the fixed support bar and therefore extend forwardly over the back of the child seat and down on the shoulders of the occupant of the child seat. This can be seen from the '995 patent mentioned in the foregoing. It can also be seen that the movement of the belts on the support bar can cause undesirable wear to the belts. further, the friction between the belts and the support bar makes it somewhat difficult to manually pull the belts against the deflection of the winding coils which causes the coils to unwind sufficiently to hold the occupant of the child seat with the belt assembly of safety for children. It is desirable to provide winding coils in a manner that allows the belts to unwind with sufficient ease and convenience when an individual attempts to establish sufficient looseness in the belts to fasten and / or release the occupant of the child seat. In addition, because the belts are wound on the support, unless an additional accommodation is provided, such as vertically spaced grooves in the back of the child seat to receive and guide the belts as they extend forward of the seat backrest. children, the belts will extend forward and down from the back of the child seat from the same position (ie, from the top of the bar of fixed supports), regardless of the size of the child or the height of their shoulders .

It is an object of the present invention to solve the problems indicated above. To accomplish this goal, the present invention provides a seat mount that includes an integrated child seat mount for a motor vehicle. The seat assembly includes a frame mounting for attachment within the motor vehicle that includes a seat cushion frame and a seat back frame mounted with respect to the seat cushion frame in a fixed operative relationship. A mattress assembly is mounted on the seat frame assembly and includes a movable mattress construction mounted for movement between (1) an adult position, wherein the mattress assembly includes the mobile mattress construction and provides a seat cushion for adult placed in an operative position with respect to the seat frame assembly, and an adult seat backrest with mattress, to house the adult's back that sits on the adult seat mattress, and (2) a position for the child, wherein the mattress assembly includes the mobile mattress construction and provides a child seat positioned in a position above the operating position of the adult seat mattress, to allow a child to sit on it, and a cushioned child seat backrest that extends upward from the padded child seat, to allow a child's back to sit on top e the cushioned child seat. In addition, the adult seat belt assembly is assembled with respect to the seat assembly constructed and positioned to be placed in immobilization relation with respect to an adult sitting on the adult seat mattress with the mobile construction in the position for adult. A child safety belt assembly is connected with the built-in seat frame assembly positioned to be placed in a restraint relationship with respect to a child sitting in the child padded seat with the movable construction in the child seat. The padded child seat provides a fixing point constructed and positioned to allow the child seat belt assembly to be releasably attached between the legs of a child sitting on the child padded seat so that it holds the assembly of seat belts for children in a restraint relationship with respect to a child sitting in the child car seat, with a moveable construction in the position for children. The child safety belt assembly includes a pair of belts, a connector structure and a driver mechanism. The pair of belts extends, each from the respective winding coils connected with an upper portion of the seatback frame, forward of the backrest of the cushioned child seat, for extension over the shoulders of a child who feels on the padded seat for children, with the movable mattress assembly in the position for children. The connector structure is associated with the belts and is constructed and positioned to be releasably connected to the attachment point, to allow the child safety belt assembly to be releasably attached to the attachment point between a child's legs who sits in the padded seat for children. The belts each have upper portions thereof wound on the respective winding rollers in such a way that the belts are generally unwound from the lower portions of the spools when the belts extend forward of the seat back of the child seat. on the shoulders of a child who sits on the child padded seat, and the connecting structure is releasably connected to the attachment point so that the child seat belt assembly is releasably fixes to the point of attachment between the legs of a child sitting on the child seat. The belt assembly is manually released from between the legs of a child who sits on the child-restraint seat by a single hand of an individual releaser of the connecting structure from the attachment point in a manner that allows an individual to lift the belts and move them away from the shoulders of the child who is sitting on the cushioned child seat with the same hand, by moving the connecting structure with the same hand over the child's head. The unrolling of the belts is generally from the portions of the coils generally higher than the lower portions when an individual lifts the belts away from the shoulders of the child who is sitting on the child seat, when lifting the connecting structure on the head of the child. boy. The control mechanism is operatively connected to the winding coils and is constructed and positioned to control the unwinding and winding of the belts by the respective coils. It can be appreciated that the space availability for the adaptive winding coils in the upper portion of the seat back frame is limited. It can also be appreciated that there is always a need to reduce the number of parts associated with a belt assembly in order to reduce costs and re-assemble lighter in weight. Therefore, another objective of the present invention is to satisfy the needs expressed in the foregoing with an innovative arrangement which is simple, compact and relatively inexpensive construction. To accomplish this goal, the present invention provides a seat assembly that includes an integrated child seat mount for a motor vehicle.

When the integrated child seat assemblies provide spring-deflected winding coils, which unwind a pair of shoulder belts, for extension over the shoulders of a child seat occupant and for connection to a fastening point between the seats. legs of the occupant of the child seat, the simple presence and position of the belts often interferes with the placement and / or removal of the child from the child seat. In many arrangements it is necessary for an adult to use one hand to keep the belts in a position that will not interfere with the previous placement and / or removal, while using the other hand to help the child enter or exit the child seat. This is an annoying and annoying procedure. Therefore, it is an object of the present invention to provide a vehicle seat mount which solves the problems indicated above. To accomplish this goal, the present invention provides a seat assembly that includes an integrated child seat assembly for a motor vehicle. The seat assembly comprises a seat frame assembly for attachment within the motor vehicle that includes a seat cushion frame and a seat back frame mounted with respect to the seat cushion frame in a fixed operative relationship. A mattress assembly is mounted on the seat frame assembly and includes a movable mattress construction mounted for movement between (1) an adult position, wherein the mattress assembly includes the mobile mattress construction that provides a seat cushion for adult placed in an operative position with respect to the seat frame assembly, and a cushioned adult seat backrest, for accommodating the adult's back that sits on the adult seat mattress, and (2) a position for child, wherein the mattress assembly includes the mobile mattress construction and provides a child seat positioned in a position above the operating position of the adult seat mattress, to house a child who sits on it, and A cushioned child seat backrest that extends upward from the child padded seat, to accommodate a child's back feels on the seat or cushioned for children. The mattress assembly additionally includes a padded headrest or headrest with respect to the seat frame assembly for housing (1) the back of an adult's head that sits on the adult seat cushion when the Movable mattress construction is in the adult position and (2) the back of the back of a large child that sits on the movable mattress construction when the movable mattress construction is in the position for children. The adult seat belt assembly is mounted with respect to the built-in seat assembly positioned to be arranged in immobilization relation with respect to an adult sitting on the adult seat mattress, with the mobile construction in the adult position. A child safety belt assembly is connected with the seat frame assembly constructed and positioned so that it is disposed in immobilization relation with respect to a child sitting in the child seat cushioned with the movable construction in the position for children. The padded child seat provides a fastening point constructed and arranged to allow the child seat belt assembly to be releasably attached between the legs of a child sitting on the child padded seat so that it holds the assembly of safety belt for children in immobilization relation with respect to a child who sits in the padded seat for children, with a moveable construction in the position for children. The child safety belt assembly includes a pair of belts or bands, each extending from the respective winding coils to the front of the backrest of the child-restraint, for extension over the shoulders of a child who feels on the padded seat for children, with a movable mattress mount in the position for children. A connecting structure is associated with the belts and is constructed and arranged to be releasably connected to the attachment point to allow the child safety belt assembly to be releasably attached to the attachment point between the legs of a child who It sits on the padded seat for children. A spring assembly is operatively connected to the winding coils, and is constructed and positioned to deflect the winding reels with a predetermined deflection force to wind the belts and provide light tensioning of the belts on a child's shoulders when the connecting structure is releasably fixed at the attachment point between The legs of a child sitting in the padded seat for children. The belt assembly is manually releasable from between the legs of a child sitting on the child's padded seat, by a single hand of an individual who releases the connecting structure from the fixing point, so as to allow the individual to lift the belts , moving them away from the shoulders of a child who sits in the child restraint seat with the same hand by moving the connecting structure with the same hand on the child's head, the connecting structure is additionally movable to carry out the movement of the belts against the deflection of the winding coils to carry out the unwinding of the belts from the coils so as to generate a sufficient clearance or space in the belts to allow the connecting structure to be placed behind the headrest. The placement of the connector structure behind the headrest provides sufficient resistance against a predetermined deflection force of the spring assembly to prevent the winding coils from winding the belts to any significant extent which may cause the connecting structure to return forward on support for the head, without manual help. Integrated seats for children are known to be provided in bench seats, usually have a low backrest, such as that provided in a van and which allows two or more individuals seated in a side-by-side relationship. Because support for the back of a child's head in a vehicle is desirable, the integrated child seat mounts on the bench seats have been equipped with headrests that are deployed to house The head of a large and / or small child when the integrated child seat unfolds. It can be seen that the back of a small child's head (for example in the range of approximately 20 pounds) simply attaches to the backrest of the child-padded seat, which provides adequate support or support. , in these arrangements or arrangements, bench-type seats have not been provided with a headrest for adults, which extends over the back of the adult seat to accommodate the back of an occupant's head of the adult seat The omission of an adult headrest in a bench-type seat that has an infant seat for children is due, in part, to limited space to provide such head support, especially in light of the space required to accommodate a headrest that is cooperative with the integrated child seat, to hold the back of the head of a large child. to provide a bench-type seat which includes an integrated child seat, and which provides a headrest that can be used by both an adult sitting on the bench seat when the integrated child seat does not It is unfolded, and also for a large child who occupies the integrated child seat deployed. To meet this need, the present invention provides a bench seat assembly that includes an integrated pair of child seat assemblies, for a motor vehicle comprising a seat frame assembly for attachment within the motor vehicle that includes a seat cushion frame and a seat back frame mounted with respect to the seat cushion frame in a fixed operative relation. A mattress assembly accommodates at least two occupants who sit in a side-by-side relationship on it. The mattress assembly includes a pair of mobile mattress constructions side by side mounted on the seat frame assembly, each of the movable mattress constructions is mounted for movement between (1) an adult position, wherein the mattress assembly includes the mobile mattress construction that provides an adult seat mattress placed in a relative position with respect to the seat frame assembly, and a padded adult seat backrest, to accommodate the adult's back that sits on the adult seat mattress, and (2) a child's seat, where the mattress mount includes the mobile mattress construction that provides a cushioned child seat placed in a position above the operating position of the adult seat cushion, to accommodate a child sitting on it, and a cushioned child seat back extending up from the padded child seat, to attach the backrest of a child seat sits on the child padded seat. The mattress additionally includes a pair of padded headrests mounted on the seat frame assembly for extension above the backrest of the adult padded seat, each of the headrests being placed in operative relation with respect to to one of the associated movable mattress constructions. Each headrest and associated movable mattress construction is constructed and arranged so that (1) the headrest houses the back of an adult's head that sits on the adult seat cushion when the construction of the associated movable mattress is in the adult position, (2) the headrest houses the back of a large child's head that is felt in the associated movable mattress construction when the associated movable mattress construction is in position for children, and (3) the backrest of the padded child seat houses the back of a small child's head that sits on the associated moveable mattress construction when the associated movable mattress construction is in the child's position.

DESCRIPTION nT7T? T.T,? NA OF THE DRAWINGS Figure 1 shows a seat assembly , which is in the form of a bench seat, and includes a pair of child seat assemblies each preferably integrated in the form of a module 12, suitable to be installed in the seat assembly as a unit. The seat assembly 10 is shown in the child's position on the right hand side of figure 1, and in the adult position on the left hand side of figure 1. The seat assembly 10 includes a pair of upstanding columns 14 for mounting the seat assembly 10 on the floor 17 of a motor vehicle. The seat assembly 10 incorporates a seat frame assembly that includes a seat cushion frame assembly 16 and a seat back frame assembly 20, which are shown in dashed lines in FIG. 1. The seat cushion frame has a rectangular tubular peripheral frame structure, and supports a covered seat cushion 18 of conventional construction. As shown, the width of the seat cushion 18 is sufficient to allow two occupants of the adult seat to sit on it in side-by-side operative positions. However, it should be understood that many of the principles of the present invention also apply to a single seat assembly adapted to accommodate only one person, and also for seat mounts that can accommodate more than two people. The seatback frame assembly 20 includes an inverted U-shaped tubular frame member 21, positioned so that the lower free ends of the leg portions thereof are rigidly fixed to the rear sides of the frame assembly 16. of the main seat and so that the portion and the central inner portion extends along the upper extent of the seat backrest. A portion 23 of the upper rail extends along the central inner portion and is rigidly fixed with respect thereto, preferably by welding or by bolts, and facilitates the attachment of the child seat module and the mounting of the safety belt of the present invention to the backrest frame of the seat, as will be more fully described in relation to Figure 2. Typically a lower tubular horizontal frame member (not shown in Figure 1) can also be part of the 20 of the seat back frame and may be welded or otherwise fixed between the lower leg portions of the main U-shaped frame member 21 shown. In addition, the rail member 23 can be provided through the extension of the main U-shaped frame member to provide additional stiffness of the frame assembly 21, if desired. A mattress assembly, generally indicated with the numeral 22, includes the adult seat mattress 18 mentioned therein mounted on the frame assembly 16, and a cushioned adult seat backrest 24. The adult seat back 24 includes the seat back frame assembly 20 on which the outer and central side mattresses 26, 28 are mounted, and the cushion 30 is placed therebetween provided by a movable mattress construction, indicated generally with the number 32. The movable mattress construction 32 moves between an adult position and a child position. In the adult position, the movable mattress construction 32 is placed within the space 34 between the side mattresses 26 and 28, and provides the cushion 30 vertically for attachment by the center of the rear part of an adult seat occupant that is it sits on the mattress 18 of the seat, as shown in the operative position in figure 1 on the left. In the child's position, the movable mattress construction 32 extends from the bottom of the space 34 in support relationship superimposed on the seat cushion 18 so as to provide a cushioned child seat, as shown in the operative position of the side right in Figure 1. The padded child seat includes a removable cushion pad 40 having a seat portion 42 and a backrest portion 44.

A pair of manually movable head supports 43 are mounted and extend upwardly from the cushioned adult seat back 24. In the figures, only the upper padded portion of the head supports 43 is shown. However, it can be seen that the upper cushioned portions of the head supports are rigidly mounted in the central lower portion of a metal member in the form of inverted U The legs extending downward from the U-shaped member have a circular cross-section and are received in slots provided in the upper portions of the cushioned adult seat back 24. The legs have vertically spaced grooves or notches that cooperatively receive spring-biased detents associated with the grooves in the upper portions of an adult seat backrest 24. The detents slide along the legs of the U-shaped member as the height of the headrest is manually adjusted and received within the notches to allow the headrest to be selectively held in the desired vertical positions above the seat backrest 24 for adult padded. It is preferred for the lower ends of the legs that are slightly flared or housed in some other manner to prevent the head support 43 from being completely detached from the cushioned adult seat back 24. Each of the head supports 43 is placed in operative relation with respect to one of the associated movable mattress constructions 32. With the movable mattress construction 32 in the adult position, the associated head support 43 can accommodate the back of an adult's head that sits on the seat assembly 22. The vertical position of the head supports 43 can be manually adjusted to accommodate a particular adult size. When the movable mattress construction 32 is in the child's position, the associated headrest 43 is attached to attach the back of a large child's head for example approximately 27 kilograms, (eg, approximately 60 pounds) that sits on a movable mattress construction 32. In this case, the headrest 43 is optimally positioned in its lowest position. When a small child (e.g., about 20 pounds) sits on the movable mattress construction 32 in the child's position, the child seat cushion 44 supports the back of a small child's head. In this case, the position of the headrest 43 has little consequence, since, even in its lowest position, it is positioned outside the range of possible engagement with the back of the small child's head. Because the head supports 43 are adapted to accommodate both the back of an adult's head and a large child's head, they are placed in a longitudinal position which is the intermediate between an ideal position to house the head of an adult. adult sitting on an adult seat mattress when the associated movable mattress construction is in the adult position, and the ideal position to accommodate the head of a large child who sits on the associated movable mattress construction when the construction of associated movable mattress is in the position for children. The movable mattress construction 32 preferably includes a main reinforcement portion 46 and a second removable peripheral reinforcement portion 48, as shown. With the movable mattress construction 32 in the adult position, the forward facing surfaces of the primary and secondary reinforcing portions 46 and 48 provide the cushion 30, and the reinforcing portions 46 and 48 fill the entire space 34 between the mattresses. 26 and 28 and extend substantially along the entire length of the adult seat back 24. It is preferred that the seat portion 42 of the cushion pad 40 only covers the main reinforcement portion 46 of the movable mattress construction 32 to allow the peripheral reinforcement portion 48 to peel off without any excess of the cushioned seat portion 42 that extends over the adult seat mattress 18. Preferably, the connection between the two reinforcing portions 46 and 48 is in the form of a rack arrangement. A more detailed description of the detachable description between the main reinforcing portion 46 and the peripheral secondary reinforcing portion 48 of the movable mattress construction 32 is described in the US patent application serial number 08 / 287,728 filed on August 8, 1994, as a continuation of the application serial number 07 / 882,610 filed on May 13, 1992 for Czapski and incorporated herein by reference. A more complete appreciation of another possible construction contemplated for the main reinforcement portion 46 can also be obtained from the patent application mentioned in the above. The seat assembly 10 also includes an adult seatbelt assembly, the buckle or fastener portion of which is generally indicated with the number 50. The adult seatbelt assembly can be of any type, and is provided to immobilize an adult who sits in the seat assembly in the adult position. The child safety belt assembly of the present invention, generally indicated with the numeral 60, is connected to the seat frame assembly (for example with the seat back frame assembly 20). The child safety belt assembly 60 includes a pair of shoulder belts 62, each extending from the respective winding coils 64 (see Figure 2) connected to the upper portion of the seat back frame assembly 20. The shoulder belts 62 extend forward of the padded child seat backrest 44, for extension over the shoulders of a child sitting on the padded child seat 42, with the movable mattress construction 32 in the position for children . A connecting structure 70 is provided to retain the shoulder belts 62 in immobilization relationship with respect to the occupant of the child seat. The connector structure 7.0 includes a main cover portion 74, preferably made of a rigid moldable plastic material, which slidably receives the shoulder belts 62 through the slots 72 provided therein. The connector structure also includes a retaining or buckle mechanism 76 provided in a lower portion thereof for releasable connection with a connector member in the form of a metal connecting tab or a clasp 78 provided with the main reinforcing portion 46 of the cushioned seat. for children. The connector pin 78 provides a fastening point which allows the child seat belt assembly 60 to be releasably attached between the legs of a child sitting on the child padded seat. The latching mechanism 76 can be released from the connector pin 78 by depressing a release button 77 provided in the latch mechanism 76. Figure 2 is a side view schematically showing the child seat module 12 of the present invention. As shown, the peripheral reinforcement portion 48 of the movable mattress construction 32 has been removed. It can also be seen that the child seat module 12, which is to be mounted on the seat back frame assembly 20 between the side mattresses 26 and 28, includes a rigid structure which, in the broader aspects of the present invention can be considered as part of the seat back frame. The rigid structure is in the form of a backing panel 80 of rigid material such as, for example, a suitable moldable plastic material. This same moldable material can be used by the horizontal support member 82, which is placed in horizontal relation superimposed on the cushion 30 when the movable mattress construction 32 is in the child's position. Preferably, removable cushion pad 40 adheres to backer panel 80 and support member 82 through the use of a VELCRO fastener material in the manner described in the '728 and' 610 applications mentioned above. The metal connector clasp 78 is deflected by a spring, by means of a spring assembly 90 to a non-operative backward position, as indicated by the continuous line position of the clasp 78 in Figure 2. The connector pin 78 has a vertically extending portion 92, which extends upwards, through the opening 93 in the rigid support 82, adjacent to a downwardly sloping edge 94 of the support 82. To fix the child safety belt assembly 60, a person attaches the cover portion 74 or the retention mechanism 76 of the connector structure 70 and retains the retention mechanism 76 on the clasp 78 by urging the retention mechanism 76 on the vertical portion 92 of the clasp 78. The mechanism 76 of retention is provided with a slot 95 for receiving the clasp 78 in a conventional manner. It can be appreciated that when the clasp 78 is biased to its non-operative back position, the distance between the vertical portion 92 of the clasp 78 and the inclined edge 94 of the rigid support surface 82 is less than the thickness "T" between the slot. 95 receiver mentioned above and the outer housing of the retention mechanism 76, as can be seen in Figure 2. Therefore, the movement of the retention mechanism 76 to a retention coupling with the clasp 78 causes the tilting surface 97 forward, of the latching mechanism 76 to contact the upper edge 99 of the clasp 78. A continued downward forced movement of the mechanism 76 on the clasp 78 causes the thickness "T" thereof to wedge between the vertical portion 92. of the clasp 78 and an edge 94 inclined until the clasp 78 moves forward in the operative position with dashed lines, indicated generally with the number 96, which prevents the deflection of spring assembly 90. The rear portion of the clasp 78 is connected to one end of a cable member 100. The cable member 100 extends rearwardly from the clasp 78, from a flexible sleeve 101, an end of which is fixed below the rigid support 82. The cable member 100 and the surrounding flexible tube 101, which constitute a Bowdine wire assembly extends up behind the rear panel 80 for connection to a controller mechanism, indicated generally with the numeral 110 in a manner that will be more fully described in the following. When the latching mechanism 76 is attached to the clasp 78 so that the clasp 78 moves to the operative position, the cable member 100 causes the controlling mechanism 110 to secure the coils 64 and prevents unwinding of the belts 62. From this In a manner, when a child occupies the child seat in the child position, and the catch mechanism 76 is fixed on the clip 78, the belts 62 will not allow the child to move forward to a significant extent. Figures 3 and 4 are schematic views showing certain portions of the child seat module 12 of the present invention. More specifically, panel 80 is shown, along with coils 64 and controller mechanism 110 mounted on a metal mounting frame assembly 130. In Figure 4 it can be seen that the control mechanism 110 is protected by a front cover housing 113, which can be formed as part of the same assembly 130. The rear panel 80 is fixed to the mounting frame assembly 130 by fasteners 114 More specifically, the mounting frame 130 is positioned so that the portion 131 of the upper frame thereof is positioned below a flange portion 132 extending rearwardly of the back panel 80, and the appropriate fasteners 114 They extend through the openings 115 through the flange portion 132 and subsequently through the openings 118 aligned in the upper frame portion 131 to produce the fixation. With reference again to figure 2, it can be seen that the fasteners 114 are also used to secure the backing panel 80 and the mounting frame assembly 130 to the seat back frame 20. More specifically, a top rail portion 23 has a forwardly extending flange portion 119, which has openings therethrough (not shown) that align with the openings 115 and 118 and which receive lower portions of the openings. the fasteners 114 through them. Preferably, the upper frame portion 131 of the mounting assembly 130 slides upward to the upper portion of the forwardly extending flange portion 119, so that the seat back frame assembly 20 supports both the mounting assembly 130 as to the backing panel 80 without resting solely on the fasteners 114. However, it can be seen that the upper frame portion 131 and the flange 132 can be mounted and fixed below the flange portion 119, if desired In any case, the winding coils 64 are rigidly connected to the upper portion of the backrest panel 80 and the seatback frame assembly 20. Referring again to Figures 3 and 4, it can be seen that the coils 64 can be considered to include a common shaft or spool assembly 120. In the broader aspects of the invention, however, the bobbins 64 can be considered to be formed solely by the belt material itself which is wound or wound on the spool assembly 120. The ends of the belt material inside the coils 64 are fixed to the spool 120 in any conventional manner. The spool assembly 120 extends through the side apertures 104 in the frame assembly 130 so that they are rotatably transported by the mounting frame 130 and operatively connected to the controller mechanism 110. The spool 120 is rotatable in opposite directions around its own axis to carry out the unwinding and winding of the belts 62 to and from the coils 64. The controlling mechanism 110 is constructed to selectively allow and prevent rotation of the spool 120 to control the unrolling and winding of the belts 62 by the coils 64. Unlike a conventional belt retraction assembly, in which a controller mechanism is used for each coil, and in which each coil rotates around its own spool, the present invention allows a single controller mechanism to be used to control the two coils, insofar as the two coils share the same reel. As a result, each belt is wound and unrolled simultaneously and to the same extent as the other, so that it extends substantially to the same length of each belt from the respective reels at all times. This prevents an irregular distribution of the belts and reduces the cost and size of the components that are required in the assembly. The small size allows the coils and the driver mechanism to be mounted more simply on the upper portion of the seat back frame. In Figures 3 and 4 it can be seen that each coil 64 consists of belt material wound on itself around the spool assembly 120. Although the coils can be housed in housings having slots through which the belts 62 can be extended, it is preferred that such housings be omitted. It has been found that the contact between the belts and the edges defining the grooves mentioned above can generate undesirable friction on the belts and interfere with the unrolling and winding of the belts. The upper portion and the flange portion 132 extending rearwardly of the back panel 80 are provided with separate openings 134, which allow the belts 62 to extend forwardly of the rear panel 80 therethrough. The edges defining the separate openings 134 guide the belts 62 as they are unrolled from, and are wound onto the spool assembly 120. The lower portion of the back panel 80 is provided with holes 138 for attachment to the lower portions of the seat back frame 20. In addition, the separate openings 138 are formed on opposite lower sides of the back panel 80 to receive the appropriate fasteners 139. The fasteners 139 are used to mount the rear panel on the opposite rear sides of the movable mattress construction 32 and to connect the lower ends of the belt 62 to the opposite rear sides, as shown in Figure 2. It can be seen that the fasteners 139 serve as a fastener for the lower ends of the belts 62 and also as a pivot point for the movable mattress construction 32. Figure 5 is a plan view, partially in section, of a portion of the child safety belt assembly of the present invention. In Figure 5, certain elements (such as the front plate of the cover housing 113) have been omitted to better show others. The cover housing 113 has opposite side walls 150 having openings 152 therethrough to receive the spool assembly 120. A ratchet assembly 156 is positioned above the spool assembly 120 within the cover housing 113, the ratchet assembly includes a metal ratchet member 158 rigidly mounted on a plastic bearing member 160. The bearing member 160 rotates with the spool assembly 120 and has a peripheral annular groove provided in a portion 162 thereof. The peripheral groove provided within the portion 162 is adapted to receive the inner edges defining one of the openings 152 in the side walls 150 of the cover housing 113. Preferably, the bearing 160 is formed of plastic material. As also shown in Figure 5, the driver mechanism additionally includes a detent member 164, which is in the form of a metal plate having opposite bolt portions 166 extending from opposite sides thereof through the respective openings 167 on opposite parallel sides 150 of the cover housing 113. The bolt portions 166 extend through the respective openings in a manner such that they allow the detent member 164 to rotate about an axis generally defined by the portions 166. Bolt The driver mechanism additionally includes a leaf spring 170 for biasing the detent member 164 in a pivotal direction toward the ratchet member 158. However, in FIG. 5, the retainer is held out of engagement with the ratchet member 158 by engagement of the detent member 164 with a lever arm 174 mounted on a rotatable, plastic wheel 176. The metal detent member 164 has a plastic coupling member 196 fixed thereto and provided for contact with the arm 174. The wheel 176 is rotatably mounted on a bearing 178, which is fixed to the reel assembly 120 . This arrangement allows the wheel 176 to rotate independently of the reel 120. This is different from the arrangement of the ratchet member 158 and the bearing 160, wherein the ratchet 158 is fixedly mounted with respect to the bearing 160, and the bearing 160 is mounts in a fixed manner with respect to the spool assembly 120 so that the rotation of the ratchet 158 can be presented only with rotation of the spool assembly 120. The spool assembly 120 is normally biased in a rotational direction which will cause the coils to free-wind the belts 62 from a generally lower portion of the coils 64. Such deflection of the spool assembly is carried out by a conventional spring assembly , generally indicated with the number 200, which is connected on one side of the mounting frame assembly 130. Figure 6 is a view taken through line 6-6 in Figure 5, and shows the retainer member 164 retained in its released position, relative to the ratchet member 158, against a deflecting force of the leaf spring 170 by the sensing action of a lever arm 174. This can be seen more fully from Figure 7, which is a sectional view taken through line 7-7 in Figure 5. Figure 7 shows the detent member 164 out of engagement with the tooth 180 provided along the outer periphery of the ratchet member 158. Referring again to FIGS. 5 and 6, it can be seen that the lever arm 174 extends radially outwardly from an annular core portion 185 of the wheel 176. It can also be seen that the wheel 176 additionally has a portion thereof. 184 of radially extending, plate-like rim that partially encircles the core portion 185, and a spring-receiving portion 188 formed on the rim portion 184. The wheel also has a hook portion 186 extending radially from the core portion 185. Preferably, wheel 176 is integrally formed of a molded plastic material. Figure 6 shows the lever arm 174 in its position in which it is counterclockwise, limited by the action of the cable 100 and the most forward position it can assume by the connector 78 in the position not operational. Figure 6 also shows the connection of the Bowdine wire assembly with the control mechanism 110. As shown, the adjacent end of the flexible tube 101 is fixed to the frame assembly 130. The adjacent end of the cable member 100 is wound around and fixed to the hook portion 186. When the connector 78 moves to its operative position 96, the cable 100 will be tensioned to cause movement in the clockwise direction of the wheel 176 in FIG. 6 against a force of a helical spring 190 connected to the spring receiving portion 188 and a connecting portion 194 of the cover housing 113. This can be clearly seen in figure 8. As can also be seen from figure 8, the movement of the wheel so as to cause the lever arm 174 to be uncoupled from the plastic coupling member 196 of the retainer member 164 to allow the pivotal or rotary movement of the detent member 164 around the bolt members 166. The biasing force of the blade spring 170 drives the pivotal movement of the detent 164 until it engages with one of the ratchet teeth 180, as shown in FIG. 9. Once the detent member 164 engages a tooth 180, the spool 120 can not rotate in the clockwise direction in FIG. 9 and thus prevents the coils 64 from unrolling the belts 62.

In Figure 9, the deflection of the spool 120 by means of the spring assembly 200 (for example, see Figure 5) can move the ratchet member 158 in a counter-clockwise direction when an excess amount is present. The slack remains in the belts 62, even after the child seat belt assembly is secured between the legs of the child seat occupant. The detent member 164 will then engage the next tooth within the teeth 180 to retain the belts 162 slightly tensioned on the shoulders of the occupant of the child seat, at all times. It can be appreciated that the degree of tension can be controlled to some extent by the spacing between the tooth 180 and the degree of deflection force provided by the spring assembly 200. Figure 10 is a perspective view showing the child seat belt assembly in an operative operation, which extends over the shoulders of a child seat occupant and which is fixed at the point of attachment between the legs of the occupant . Because the shoulder belts 62 are wound or wound in a clockwise direction, in FIG. 10, around the spool assembly 120, the shoulder belts 62 are generally unwound from the lower portion of the belt. the coils 64. In figure 11, the child safety belt assembly is shown in its non-operative position where it has been manually released from the child's legs by a single hand of a person. This can be easily accomplished by an individual by using the thumb to press the release button 77 onto the retention mechanism 76, and lifting the belts away from the child's shoulders with the same hand when moving the connector structure 70 over the child's head It can be seen from Figure 11 that the belts 62 are unwound from the portions of the coils 64 generally superior to the previous lower portions (for example, compare the arrows in Figures 10 and 11) when a person lifts the belts away from the belts. The child's shoulders when lifting the connecting structure on the child's head. In Figure 11, the individual lifting of the connecting structure 70 can simply release the connecting structure so that the belts 62 rest on the head support 43 so that the connecting structure rests or hangs behind the head support. 43. The deflection force provided by the spring assembly 200 and the weight of the connector structure 70 are carefully chosen so that the weight of the connector structure 70 behind the headrest 43, together with the resistance provided by the belts 62 can slide over the headrest and provide sufficient resistance to the biasing force of the spring assembly 200 to prevent the spring assembly 200 from wrapping the belts 62. This leaves both hands of a person free to remove the child occupying the seat of the child seat. Because the belts 62 are wound on the coils 64 so that they are unwound from the lower portions of the coils, less friction is imposed on the belts 62 as they rise in the position shown in Figure 11. More specifically, if the belts 62 are unwound from the upper portions of the coils 64 (for example, when they are wound in a counter-clockwise direction in the spool assembly 120, as opposed to the direction in the direction of the clock hands shown in Figures 10 and 11), there could be more interference with other portions of the seat assembly 10 (e.g., the upper portions within the backrest 24 of an adult seat) to the extent that the shoulder belts 62 are unwound from the coils 64. In addition, because the belts 62 are unwound from the lower portions of the coils as mentioned above, the belts naturally tend to unwind from the relatively higher positions with respect to the coils as the material of the belts is lowered of the coils 64. Because relatively less belt material is required when holding a small child compared to a large child sitting on the movable mattress construction 32, the coils 64 retain more belt material when fastened to the belt. a small child by the belt assembly 60. With more material retained in the coils 64, the belts 62 will extend from a relatively low position from the coils 64. In contrast, when a large child occupies the child seat, more belt material is required and the coils 64 are more depressed , so that they unwind from a relatively higher position. This arrangement provides a slight adjustment of the position at which the belts 62 are unrolled in order to comfortably accommodate children of different sizes. Therefore, it will be noted that the objects of the invention have been carried out completely and effectively. However, it will be understood that the above preferred preferred embodiments have been shown and described for the purpose of this invention, and are subject to change without departing from such principles. Therefore, this invention includes all the modifications encompassed within the spirit and scope of the following claims. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
