p F. A. ABRAHAM CONVERTIBLE BABY SEAT Filed. Feb. 24, 1925 Patented Sept. 5.3, 1927.



Application filed February 24, 1925. Serial No. 11,289.

The object of this invention is to provide a simple structure which is converti )le into either a high-chair especially for use at table, or a nurser -chair, or a swing as occasion may deman the construction being inexpensive and strong and such that the seat may be folded into an exceedingly compact condition for convenience in handling, acking and transportation, as more ful ereinafter set forth.

In the drawing- F i 1 is a perspective view of the seat adjuste for use as a high-chair;

Fig. 2 is a similar view of the seat adjusted for use as a nursery-seat;

Fig. 3 is a similar view of the seat adjusted for use as a swing;

Figs. 4 and 5 are detail views hereinafter more particularl described.

Referring to t 1e drawing annexed by reference-characters, designates the central or main frame which consists of a heavy wire bent into rectangular form. This rectangular wire-frame has stretched across it the nurser -seat fabric 11, this fabric being detachab y connected to the four frame-bars by hems 12, the free edges of which are detachably connected to. the under side of the fabric inside of the frame-bars by means of a hook-and-eye arrangement, the eyes 13 being attached permanently to the under side of the fabric by strips of fabric 14 and the hooks 15 being attached to said free ed es.

This makes the nursery-seat fabric rea ily removable for the purpose of cleaning, etc., and at the same time insures tautness in all directions sufficient to support the weight of the child.

A back-frame fabric 16 is attached to the rear bar of the seat-frame through the medium of a rectangular wire-frame 17 whose vertical side rods are pivotally connected to said rear bar of the seat-frame by means of eyes 18 formed on the lower end of said vertical rods. The fabric is attached to the back-frame by suitable hems formed in the edges of the substantially rectangular piece of fabric used for this purpose. The eyes 18 enable the back member to be folded down flat over the seat member.

Another frame consisting of a rectangular piece of fabric 19 hemmed to a rectangular wire-frame 20 is pivotally connected to the front bar of the seat-frame by eyes 21. This stifi' front frame is adapted to be swung over upon the seat frame and reinforce the same when the appliance is used as a chair or a swing, as shown in Figs. 1 and 3. When the appliance is to be used as a nursery-seat, this front anel or frame is swun over forwardly an allowed to hang free y. When the appliance is to be used on a chair of the proportions shown in Fig. 2, this depending front frame will serve as a leg-rest and as a guard. For the purpose of hanging the appliance in proper position for use as a highchair or as a nursery-seat, I provide the back frame with a pair of hooks 22 which are pivotally connected to the top bar of the back-frame so as to adapt them to be hung overthe top bar of a dinner chair, as shown 111 Figs. 1 and 2. When thus hung over the back of a chair, the seat will be suspended at a desirable distance above the seat of the chair, as illustrated.

Fabric suspension tape-members 23 are employed to serve as side-guards and also to hold the seat-member in proper relation to the back-member. These suspension tapes or members connect the two upper corners of the back-frame to the two front corners of the seat-frame; for convenience in connectmg these tapes to their respective frames, I form the side-bars of the two frames into eyes 24. For the purpose of holding the child in the seat, I provide a body-band 25 WhlCll is attached to the fabric of the backframe and extends around in front of the suspension members 23 so as to pass under the arms of the baby. For the purpose of disconnecting this body-band 25, I sever it at one point and provide one end with a snap-hook 26 and t e other end with a ring or eye 27. To keepl the child from slipping out forwardly off t e front edge of the seat, I provide a central strap 28 which is slidably attached to the body-band 25 at its upper end (by means of a loop formed on the upper end of said strap 28) and detachably attached to the front edge of the seatframe by means of a hoolGand-eye arrangement 29. This central strap 28 is positioned to lie between the legs of the baby and therefore will, together with the body-strap 25 and the suspension members 23, hold the child safely in the seat, preventing it wriggling off the seat in any direction. The body-band 25 is desirably stitched to the si7de straps 23 where they cross the same, at 3 When not in use, it will be seen that the three panels or frames may be readily folded over on each other to make a very com act article. The straps 23, 25 and 28 are of exible fabric and may be disposed of in any suitable way; for instance, they mgyhbe folded between the frame members. en the appliance is used as a swing, as shown in Fig. 3, the chair-hooks 22 are out of use and instead four suspending tapes 30 are used, each one of these being provided with a snap-hook 31 at its lower end for detachable attachment to the suspension loops 24. The tapes at their upper ends ma be supplied with similar snap-hooks or ot er means (not shown) for suspending them from an overhead structure. These suspending members 30 are desirably made of fabric similar to the other fabric members, so that they may be readily placed between the framemembers in ackin or laced in the container in w ich t e f0 ded appliance is enclosed.

It will be observed that a feature of importance is the stiff frame 20 covered by the taut fabric 19 and pivotally mounted on the front bar of the seat-frame. This stiff frame, as will be observed, is a little narrower than the seat-frame, so that it may he read ily swun over upon the top surface of the fabric. 0 the seat-frame and will lie closely thereagainst. By making this frame 2019 in this manner, it is unnecessary to provide fastening devices for clamping it down on the seat-frame, while at the same time this swinging frame serves to provide a substantial closed seat in connection with the nurscry-seat 11.

A further feature of importance is the provision of a closed eye 24 at each of the upper corners of the back frame and a simi-' lar eye at each of the front corners of the seat-frame, whereby these eyes may be utilized as connections for the guard suspension-straps 23 and also for the swing-straps 30, these latter being detachably connected to the eyes 1? means of snap-hooks 31. In this way, I p ovide a simple construction for readily converting the folding chair into a swing.

The free edge of the fabric 19 adjacent to the front edge of the main seat-frame is rovided with an extension-flap 36 which, w en the fabric 19 lies over upon the main seat, folds down over the front bars of the main seat and thus furnishes a finish or valance along the open side of the wire frame 20 and thus nicely disposes of the raw edge of the fabric that would otherwise be presented by the front edge of the seat. This flap is desirably formed by providing the edge of the fabric with a wide hem.

What I claim is:

1. A seat convertible into either a hi hehair or a nursery-chair or a swing, embo ying a seat-frame having sus nsion eyes at its two front corners, a backme pivotally frame and serve as a reinforcing cover for v the same, said eyes at the front of the seatframe as well as the eyes at the top of the back-frame being adapted to serve as eon nections for the swing members.

2. A bab -seat embodying a seat-frame carrying a abric nursery-seat having a hole, a back-frame pivotally attached to the aforesaid frame and carrying means at its upper ed e for suspendingait, side sion mem ers connectin t e 11 per en of the back-member to the forwar edge of the seat-frame, straps for holding the child in the seat between said suspension membe and a stiff cover-member pivotally attachzl to the front ed e of the seat-frame to adapt it to hang in out and serve as a leg-rest and to fold over on the seat-frame and reinforce the same and cover the hole therein, said cover-member having substantially the area of the nursery-seat.

3. A baby-seat embodying a rectangular wire seat-frame, a fabric seat-member stretched on said frame havin a hole, a stiff seat-cover 'pivotall attac ed to the front edge of said seatrame and adapted to be swun forwardly and downwardly to serve as a eg-rest guard and over upon the seat-frame and reinforce the same and cover the hole therein a back-member attached to said seat-member and means for holding it in pro er relation to said seat-member, said ac -member being provided with means for sus ending it on the back of a chair and sai seat-cover consisting of a fabric-covered wire-frame of substantially the same area as the seat-member.
