Abstract
A seating unit for accommodating an adult in a seated position and having a child restraint seat convertible from a position stored within the back of the adult seat to a position for holding and restraining a child. The child restraint seat has a generally U-shaped restraint bar member which extends horizontally from the seat back in the open position and which pivots about the ends of the legs to a vertical closed position, wherein the restraint bar lays flush with the forward surface of the seat back and the bight portion of the U shape forms the top edge of the seat back. The child seat also has a seat cushion portion which pivots about its lower edge to lay horizontally in the opened position upon the adult seat and which pivots vertically to lay flush in the seat back and nest between the legs of the restraint bar in the closed position.

Description
BACKGROUND OF THE INVENTION

The present invention relates to child restraint seats. Such seats are most widely known in use with automobiles. However, the present invention is also applicable to vehicles generally, such as busses, planes, trains and boats for example, and to theater seating and the like.

In typical use in automobiles for example, a child restraint seat is a bulky, rigid apparatus into which a child is strapped and which is fastened in a seating position in a car. Because the devices are bulky and are bothersome to remove and replace, child restraint seats are typically left in place in the car for the child's use. Only when circumstances necessitate the use of the seating position by an adult, is the child seat generally removed from the car. Child restraint seats are thus seen as somewhat of a necessary nuisance, typically reserved for use in cars and seldom, if ever, used in other types of vehicles or with other types of seating. While social acceptance and legislative requirements for the use of child restraint seats in cars is commonplace, there is also social and legislative interest in requiring their use in other vehicles, including busses, planes and trains.

While the desirability of an adult seat which is convertible to a child restrain seat is apparent, attempts to supply this need have had their own limitations and problems. The patent to Dorto (U.S. Pat. No. 4,749,229) for example, discloses a device which inherently limits its utility by creating an overhead obstruction to the child who uses the seat, requiring the child to be of sufficiently small size to sit within a recessed area in the back of an adult seat. The same problem is found in the patents to Irvin (U.S. Pat. No. 4,722,568) and to Hassel, Sr. (U.S. Pat. No. 4,540,216) for example. Other devices, such as the one shown in the patent to Casale (U.S. Pat. No. 4,664,443), are impractical because they require excess volumes of space.

SUMMARY OF THE INVENTION

The present invention addresses these problems with a practical seating unit for accommodating an adult in a seated position and having a child restraint seat convertible from a position stored within the back of the adult seat to a position for holding and restraining a child. The child seat of the present invention includes two portions of the adult seat back which pivot forward to form a child seat cushion and a restraint bar and which pivot closed to form a smooth back support for an adult seating position. The restraint bar portion generally resembles an inverted U in the closed position with the bight portion positioned to form the top edge of the adult seat back. Thus, a height restricting portion of the back does not remain when the child seat is deployed. The child seat cushion portion folds into a closed position to nest inside the closed restraint bar portion and forms the mid and lower back support for the adult seating position.

In one aspect of the invention, the child restraint bar and seat cushion are mounted to a framework such that the seat cushion can be slid forward, inclining the child seat back and providing a reclined seating position for the child.

These and other objects, advantages and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings in greater detail, the seating unit 10 of the present invention has a restraint bar 20 and a child seat cushion 30 which are mounted with a frame 40 for folding into a closed position to become a part of an adult seat back 11.

Restraint bar 20 is a generally U-shaped member which is built-up with safety padding and upholstery as shown in FIGS. 1 and 2. A wedge portion 21 on bar 20 is built-up with an extra thickness of padding to provide added safety to a child by presenting a larger surface area and a deeper padding in the area where a child's face might contact the bar in a sudden stop or accident. Bar 20 has legs 23 and is pivotally fastened to frame 40 at pivots 25 (FIG. 3), near the ends of legs 23. Bar 20 canpivot between an opened horizontal position (FIG. 2) and a closed vertical position (FIG. 1). In the opened position, bar 20 surrounds a child using seating unit 10, restraining the child. The restraining properties of bar 20 are preferably supplemented by a typical child restraint harness. In the closed position, bar 20 is folded into back 11 with an edge surface 27 flush with a top surface 13 of back 11, and a face surface 29 of bar 20 flush with a face surface 15 of back 11. Child seat cushion 30 also pivots between an opened horizontal position (FIG. 2) and a closed vertical position (FIG. 1). Cushion 30 is pivotally attached at each side and near its lower edge 31 to frame 40 at pivots 35. A framing plate 33, shown in FIGS. 3 and 4, is built into each side of cushion 30 near edge 31. Plates 33 pivot wih cushion 30 and provide a foundation for pivotally connecting the cushion to frame 40.

Frame 40 has two vertical side braces 41 which are pivotally connected, near their upper end 43, to back 11 via vertically sliding tracks 50 (FIG. 5) such that the lower ends 45 of braces 41 can pivot away from back 11 and upper ends 43 of braces 41 can slide down the tracks. Tracks 50 are elongated channels having a "C" cross-section for retaining a slide, preferably a wheel 51, which in turn is pivotally connected to upper end 43 of side brace 41 by a stub axle 53. Lower ends 45 of braces 41 are pivotally connected at pivots 35 to one end of telescoping rods 60. As shown in FIG. 6, an inner "C"-sectioned channel 61 is slidably retained within an outer "C"-sectioned channel 63 to provide a telescoping action. With a channel 61 pivotally connected at an end to a plate 33, an opposing end of channel 63 is pivotally anchored in back 11. A child seat back foundation 37 extends between braces 41 and is located in the recess 38 (FIG. 3) behind the restraint bar 20 and cushion 30. Foundation 37 is preferably made from a sheet of 16 gauge steel which is bent to form a two inch deep basket behind braces 41 and which is welded along each side to braces 41.

In operation, unit 10 is opened by pivoting cushion 30 forward about edge 31 until cushion 30 is in a horizontal position, laying on adult seat 17. Restraint bar 20 is likewise opened by pivoting forward about pivots 25 until bar 20 is cantilevered forward in a horizontal position. An upholstered recessed area 19 is revealed in back 11 when bar 20 and cushion 30 are opened and forms the back for the child seat. Cushion 30 is pulled forward and rods 60 telescope to adjust the incline of the child seat back. A child is placed between legs 23 of bar 20 to sit upon cushion 30. The child is preferably strapped into seat 10 with a typical child restraint harness.

While a preferred form of the invention has been shown and described, other forms will now be apparent to those skilled in the art. Therefore, it will be understood that the embodiments shown in the drawings and described above are merely for illustrative purposes, and are not intended to limit the scope of the invention which is defined by the claims which follow.
