Technical Field of Invention
This invention relates to vehicle seats and more particularly to vehicle seats integrated so as to provide an adult seat in an adult seat mode and a child's seat in a child seat mode.
Background of the Invention
The type of integrated vehicle seat herein contemplated is the type disclosed in commonly assigned copending U.S. application Ser. No. 07/699,375, filed May 14, 1991, entitled "Integrated Child Seat for Vehicle", a continuation of which issued Jul. 6, 1993, as U.S. Pat. No. 5,224,756.
As a lead up to the '756 patent subject matter, certain integrated child seats were made known to the public as prior art. These integrated child seats were constructed to include a vehicle seat comprising a frame assembly for securement within a vehicle including a seat frame assembly and a seat back frame assembly operatively connected with the seat frame assembly so as to be capable of being disposed in a fixed operative position with respect to the seat frame assembly. A seat cushion was carried by the seat frame assembly in a position to enable an adult occupant of the vehicle to sit thereon in an operative position. Side cushions were carried by the seat back frame assembly in positions to be engaged by opposite sides of the back of an adult seat occupant sitting on the seat cushion in the operative position with the seat back frame assembly in the fixed operative position. The side cushions were spaced apart a distance sufficient to define a child receiving space therebetween of a size to enable a child to be disposed therebetween. A plurality of cushion assemblies were mounted on the frame assembly including a movable cushion assembly mounted on the frame assembly for movement between (1) an adult mode position wherein the movable cushion assembly is disposed within the space between the side cushions and provides adult back cushions for engaging the back of an adult seat occupant sitting on the seat cushion, and (2) a child mode position wherein the movable cushion assembly extends from the space between the side cushions to provide a cushioned child's seat extending from the bottom of the space in overlying relation to the seat cushion and the plurality of cushion assemblies provides a cushioned child's seat back extending upwardly from the cushioned child's seat within the space between the side cushions, and a cushioned child's head support above the cushioned child's seat back. A child's seat belt assembly was disposed in operative relation with the seat back frame assembly and extended forwardly of the cushioned child's seat back for extension over the shoulders of a child sitting on the cushioned child's seat. The movable cushion assembly included a rigid seat structure and a structural connection between the rigid seat structure and the seat back frame assembly enabling the movable cushion assembly to be moved between the adult mode and the child mode positions. The rigid seat structure provided a rigid anchor point for the child's seat belt assembly between the legs of a child sitting on the cushioned child's seat.

Best Mode of Carrying Out the Invention
Referring now to the drawings in greater detail, FIG. 1 illustrates a vehicle bench seat 10 having a seat cushion assembly 12 and a seat backrest assembly 14. Either one or two side-by-side toddler or child seat modules 16, integrated with the backrest assembly 14, provides a retractable fold-down, articulated seat back section 18 adapted for swinging movement in and out of a recess provided in the backrest assembly 14. As best seen in FIGS. 2 and 11, the articulated seat back section 18 includes a first movable cushion assembly or bolster segment 19 and a second movable cushion assembly or bolster segment 20 which are articulated at their outer adjacent opposed edges by a suitable flexible and detachable hinge 21. The detachable hinge 21 may include suitable separable fastener means, such as a slide fastener (FIG. 23) or a zipper for detaching the second bolster segment 20. The zipper may be covered by a flap 25 (FIGS. 12 and 16). The first cushion segment 19 has one side adapted to serve as a back support in an adult seating mode and its other side as a seat bottom in a child seating mode. The second bolster segment 20 has one side adapted to serve as a upper back support in an adult seating mode and its other side as a leg support in a child seating mode.
With reference to FIG. 2, the articulated seat back section 18 may be pivoted downwardly from the backrest 14 about a transverse pivot axis "A" (FIG. 3) adjacent the first cushion segment 19 lower rear end thereof, to form a modular child seat 22 (FIG. 2), while leaving adjacent backrest sections 23 and 24 of the seat backrest 14 intact.
A back panel 26, formed of suitable structural plastic material, such as glass reinforced polypropylene for example, is secured to seat support means, such as a back wall 30 (FIGS. 12, 18 and 19), by suitable bracket means 32, as will be explained. The bottom end portion of the back panel 26 is secured to the front legs of a pair of substantially Z-shaped seat back 27 brackets (FIGS. 17 and 18) (one adjacent each lower corner of the back panel) by fasteners 28. The brackets 27, in turn, are secured in any suitable manner, such as by rivets or welding, to the front side of respective vertically oriented straps 29. The upper end portions of the straps 29 are secured in any suitable manner, such as by welding, to the back side of a J-shaped lower cross bar 34. The straps 29 are adjacent a vehicle floor pan 35 (FIG. 17). An adult seat belt 33a is secured to a clip 33b which, in turn, is secured by a fastener 33c to each strap 29.
The modular child seat assembly 22 is shown in FIG. 3 and includes the articulated seat back section 18 together with the back panel 26. As an initial step to forming the child seat of FIG. 2, the articulated seat back section 18 is withdrawn from the backrest 14. The articulated seat back section 18 is moved into its child supporting in-use FIG. 2 position by folding down the seat back section 18 from a generally rectangular shaped backrest recess defined by the child seat back panel 26 and a pair of rearwardly extending, recess side walls 36 and 38. The side walls 36 and 38 are formed by the inboard opposed sides of the respective backrest side cushions or sections 23 and 24.
With reference to FIG. 8, the back support first cushion segment or child seat bottom 19 includes a rectangular seat pad support platform 40, formed of suitable structural plastic material. As best seen in FIG. 9, the support platform 40 has a central planar portion 42 bordered by a peripheral downwardly offset frame-like ledge portion 44 extending therearound. An endless trough or slot 46 is formed in the top surface of the platform 40 located a predetermined distance inside the outer perimeter thereof, providing a continuous boundary between the central portion 42 and the ledge portion 44, for a purpose to be described.
As seen in FIGS. 6, 8 and 10, a pair of perpendicularly extending mounting flanges 45 are formed adjacent the rear corners of the plastic support pan 40 with axially aligned openings 47 formed therein. The openings 47 are adapted to having suitable fasteners 48 (FIG. 10) extended therethrough to pivotally secure the platform 40 to suitable mounting brackets 50 (FIG. 12) fixedly secured to extend from the module back panel 26.
A crotch belt 54 extends longitudinally beneath the seat pad support platform 40, and thence upwardly through openings 56 and 58 (FIG. 6) formed therein, to be secured at the rear end thereof by a suitable mounting bracket or plate 60. The bracket 60 is secured to the platform 40 by suitable fasteners 61 (FIG. 6). A conventional seat belt buckle 62 is secured to the exposed forward end of the belt 54.
As shown in FIG. 5, a single adjust belt 72 extends through a slotted opening 74 formed in the back panel 26 and is connected to a safety harness including a T-bar 76 and twin shoulder belts 78 and 80 extending through respective horizontally disposed restraint slots 82 and 83 in the back panel 26 and thence through a releasably interconnected guide member 84 and slotted ends of a pair of opposite hand connector members 85. The latter are adapted to be releasably connected to the buckle 62. The extensions 87 and 88 of the respective belts 78 and 80 are secured by brackets 89 to the mounting flanges 45. The extensions 87 and 88 serve to mount over the child's thighs.
A removable cushion pad assembly 90 (FIG. 4) having a suitable sheet cover formed from flexible material such as vinyl (FIG. 4), includes respective seat and back segments 92 and 94 connected by a flexible hinge 96 and is removably mounted against the support platform 40 and back panel 26, as shown in FIG. 3. A rectangular opening 100 is formed in the seat segment 92 for mounting around the crotch belt 54 out of the plastic seat support platform 40, and the upper edge 102 of the back segment 94 fits against the back panel 26 up to a point just above the openings 82 and 83. As shown in FIGS. 3 and 4, a strip of Velcro 140a, or other suitable hook or loop tape strips, is mounted on the back side of the pad 90, adapted to engage a mating Velcro or other suitable strip 140b mounted on the back panel 26 to retain the pad 90 in its upright position.
FIG. 28 shows an alternate pad 90' covered with suitable cloth or woven material wherein at least the backside portion has a pile-like outer surface adapted for engagement by a suitable hook-type Velcro strip.
As shown in FIG. 9, an outer cloth or other material, such as vinyl or leather, cover 106 is wrapped around the cushion segment 19. A plurality of spaced holes 108 are formed in the plastic seat pad support platform 40 intermediate the trough 46 and the edges of the ledge portion 44. A flat retainer 110 includes a flange 112 formed on the inner edge thereof, and suitable fasteners 114 extend through openings 115 formed at spaced intervals along the center line thereof, and thence through the cover 106 into the seat bottom 19. The fasteners 114 are aligned with, and snap into, the holes 108. The cover 106 is wrapped around the flange 112 and retained thereby when projected into the trough 46, as shown at the left side of FIG. 9.
Mating Velcro strips or other suitable hook and loop tape strips 116a (FIG. 4) and 116b (FIG. 6) are respectively secured to the underside of the seat segment 92 and the upper side of the plastic seat support platform 40, respectively, to hold the seat segment in place. In the case of pad 90', having a cover with a fabric-like pile outer surface, the strips 116a (FIG. 4) are not required, and the strip 116b is a hook-type strip.
After use, and when no toddler is on board, the leg support 20, the cushion segment 19, and the associated support platform 40 are folded up in an arcuate motion to resume the function of being a portion of a normal motor vehicle or aircraft seat back against the back panel 26 between the sides 36 and 38, to complete the seat back structure.
As shown in FIGS. 5-11, the belts 78 and 80 connect through the T-bar 76 (FIG. 6) to the belt 72. The latter extends beneath the plastic support platform 40 and through a front opening 122 and the rear opening 58. It passes through a flat bracket 124 (FIGS. 6 and 11) prior to exiting through the opening 122 (FIGS. 6 and 10), wherein it may be retained in position by a serrated surface 126 (FIG. 10), serving as a tension adjuster on a cross member 128 which is pivotally mounted on a pin 130 (FIG. 11) between oppositely disposed side walls 131 of the bracket 124. A coil spring 132 operatively connected between the cross member 128 and the pin 130 retains the serrated surface 126 in a gripping engagement against the adjust belt 72 until a shoulder adjustment pull strap 134 extending through the front opening 122 is pulled forward to pivot the cross member 128 and thereby release the adjust belt 72 and permit it to be pulled to tighten the shoulder belts 78 and 80 around the child. The pull strap 134 is mounted around a bar 136 connected to forward edges of the cross member 128 by levers 138. A belt tab 140 (FIG. 6) is secured at the end of the adjust belt 72 to facilitate the pulling-to-tighten process.
Referring now to FIG. 13 and once again to FIGS. 3 and 5, it is noted that the two restraint slots 82 and 83 communicate at their outwardly disposed ends with the lower ends of two vertical transfer slots 142 and 144 respectively. The vertical transfer slots 142 and 144 communicate at their upper ends with diagonally oriented, upwardly extending inversion slots 146 and 148 respectively and lateral transfer slots 150 and 152 respectively. The lateral transfer slots 150 and 152 extend to respective downward vertical transfer slots 154 and 156 which communicate with two belt restraint slots 158 and 160 respectively between the ends thereof. The two sets of slots are formed in the panel 26 and comprise two horizontally spaced and generally horizontally aligned pairs of vertically spaced belt receiving restraint slots 82 and 158 and 83 and 160 and a transfer slot extending between each pair of restraint slots. The transfer slot which extends between the pair of slots 82 and 158 is provided by the three communicating transfer slots 142, 150 and 154. The transfer slot which extends between the pair of slots 83 and 160 is provided by the three communicating transfer slots 144, 152 and 156. When it is necessary to accommodate a larger child, the twin shoulder belts 78 and 80 are moved out of the pair of restraint slots 82 and 83 respectively (FIG. 24), into the vertical transfer slots 142 and 144 and thence into the diagonal inversion slots 146 and 148 (FIG. 25). The trailing edges of the belts 78 and 80 are then moved progressively through into the lateral transfer slots 150 and 152 (FIG. 26) to the vertical transfer slots 154 and 156 for seating in the upper belt restraint slots 158 and 160 (FIG. 27).
As shown in FIG. 4, the back segment 94 of the pad 90 includes only horizontal slots 168 and 170 and horizontal slits 172 and 174 continuing from the respective slots 168 and 170, to accommodate the adjustment of the belts 78 and 80 into either the lower restraint slots 82 and 83 or the upper restraint slots 158 and 160.
A head support cushion assembly 175 (FIGS. 12 and 14) is pivotally mounted on an inverted J-shaped upper cross bar 176 (FIG. 14) overlying the upper portion of the back panel 26. The head supporting cushion assembly 175 includes foam material 177 covered on the back side thereof with a plastic backing 178 having a substantially C-shaped clamp 179 end portion adapted to flex so as to snap over the upper cross bar 176, as shown in FIG. 14.
