4 Claims. (Cl. 155131) This invention relates to an auxiliary seat for high chairs and the like.

The present invention is to provide an auxiliary seat particularly adapted to be arranged'on the seat of an infants high chair so as to securely support an infant thereon and prevent or minimize the possibility of the infant sliding therefrom.

Another object is the provision of an auxiliary seat for a conventional infants high chair and the like which is designed to support the infant on top of the seat so that the infants knees are elevated and his weight is shifted rearwardly to his hips whereby the latter will be retained against the back of the chair so that the seat has a tendency to keep the infants back straight and thereby promote good posture in a sitting position.

A further object is the provision of an auxiliary seat adapted to be clamped or otherwise attached to the seat portion of a conventional infants high chair and the like and which auxiliary seat is formed with a rearwardly sloping upper face so as to support an infant thereon with his knees elevated and his weight shifted rearwardly to his hips.

Still another object is to provide an auxiliary seat primarily adapted to be clamped to the seat portion of a conventional infants high chair and the like wherein the upper face of the auxiliary seat is formed with a concave and rearwardly sloping seat area which supports the infant thereon with his knees elevated and his weight shifted rearwardly to his hips.

A still further object is to provide the seat of a conventional infants high chair with a hinged seat portion which is adapted to be retained in an angularly rearwardly sloping position so as to securely support and. retain an infant thereon.

Still a further object is the provision of a seat for an infants high chair having a hinged portion adapted to be folded upwardly into position against the chair back in inoperative position and to a downwardly disposed angularly extending operative position in which latter position an infant is supported thereon with his knees elevated and his weight shifted rearwardly to his hips. These and other objects and advantages will be apparent by considering the following specification in connection with the accompanying drawings, wherein:

Figure 1 is a side elevation of the preferred form of my improved auxiliary seat in assembled position on the seat portion of a conventional infants high chair;

Figure 2 is a top plan view of the preferred form of my improved auxiliary seat;

Figure 3 is a section on the line 33 of Figure 1;

Figure 4 is a section on the line 44 of Figure 2;

Figure 5 is a top plan view of a modified form of my improved seat arranged in the seat of an infants high chair and hingedly connected thereto; and

Figure 6 is a section on the line 6-6 of Figure 5.

Referring more particularly to the drawings, wherein similar reference characters designate like parts throughout the several views, the numeral 1 represents generally "ice a conventional infants high chair and the like which includes a horizontally disposed flat seat section 2, legs 3, upwardly and rearwardly sloping back member 4, and arm rests 5. In. the preferred form of my invention, an auxiliary seat 6 is formed of wood, plastic or other suitable material such as sheet metal or the like. The seat 6 is substantially rectangular and of less width and length than the seat section 2 so as to occupy only the rearward portion'of the latter, and the seat 6 is provided with a fiat bottom face 7 which rests on the seat section 2. The upper face 8 of the seat slopes downwardly and rearwardly from front to rear and is formed with a concave portion 9 for receiving the buttocks of an infant in an obvious manner.

In the preferred form of the invention shown in Figures 1 to 4, the seat 6 is removably and pivotally connected to the chair seat by a pair of clamping members 10. The members are of somewhat C-shape whereby the transversely extending spaced legs 11 and 12 thereof are adapted to be positioned over the side edges of the chair seat 2 so that clamped screws 13, projecting through apertures 14 in the clamp legs 12, may be tightened into positions against the underside of the seat 2, as best shown in Figures 3 and 4. The clamp legs 11 extend parallel to the upper face of the seat 2 and are adapted to project through a bearing sleeve 15 arranged within a bore 16 extending transversely through the seat 6 adjacent the rear thereof. As the rear edge of the seat 6 is rounded, as at 17, it will be apparent that the seat 6 may swing upwardly to the dotted line position of Figure l where the same will bear'against the chair back 4 in an inoperative position.

When the seat 6 is in a lowered or operative position, it will be understood that an infant may be seated thereon. Due to rearwardly sloping upper face 8 and concave portion 9 of the seat, the infants knees will be raised or elevated so that his weight will be shifted rearwardly and downwardly to his hips so that the latter will be positioned and retained against the back 4 of the high chair. In this connection, the angle of elevation between the forward portion of the seat 6 and the chair seat 2 is preferably between eight and ten degrees which satisfactorily. causes the infants knees to be raised. Because the back 4 of the chair extends upwardly and rearwardly at an angle, as shown in Figure 1, this will effect a chair which has an angle of approximately ninety degrees. Consequently, the infant cannot slide forwardly in the chair and the seat 6 has a tendency to retain the infants back straight against the back 4 of the chair and thus promote good posture in a sitting position.

My improved auxiliary seat is designed to fit into most conventional high chairs.

Referring to the modification illustrated in Figures 5 and 6, an infants high chair 17' includes a horizontally disposed flat seat section 18, legs 19, upwardly and rearwardly sloping back member 20, and arm rests 21. The seat section 18 is formed with a substantially rectangular opening 22 spaced from the front and side edges thereof and extending to the back 20, within which opening is snugly seated a seat portion 23. By reference to Figure 6, it will be noted that the forward edge of the opening 22 is tapered downwardly, as at 24, and the corresponding forward edge of the seat portion 23 is tapered upwardly and forwardly, as at 25. The rear edge of the seat portion is also tapered upwardly and rearwardly, as at 26, and suitable leaf hinges and the like 27 are suitably secured to the rear edge of the seat portion and the chair back 20. Thus, in the normal lowered position of the seat portion 23, the forward edge 25 will flatly engage the edge 24 of the opening and the hinge leaves will be in abutting relationship, in an obvious manner, so that the seat portion 23 will be securely supported in the opening 22 wherein the upper faces of the flat chair seat section 18 and seat portion 23 will be on the same horizontal plane.

In the modified form, the seat portion-23 is supported in the elevated or raised position of Figure 6 by relatively narrow fiat fingers 27 arranged on the upper face of the seat section 18 adjacent the forward edge of the opening 22. The fingers are provided with elongated slots 28 through which headed screws or the like 29 project into the body of the section 13 so that the fingers 27 may be slidably adjusted from the full line to the dotted line positions of Figure 5, in an obvious manner. That is, the fingers are slidably moved relative to their retaining screws 29. In the full line position of Figure 5, it will be noted that the fingers 27 clear the opening 22 to permit of the seating of the seat portion 23 within its opening 22, whereas, When the seat is first raised and the fingers 27 moved to their dotted line positions, the fingers will project into the opening and will serve to engage the underside of the seat portion 23 and support the same in the raised or elevated position of Figure 6. In the last mentioned position, it will be apparent that the infants knees will be raised or elevated so that his weight will be shifted rearwardly and downwardly to his hips so that the latter will be positioned and retained against the back 20 of the high chair.

While I have described and illustrated preferred and modified forms of my invention, it is to be understood that various changes and improvements may be made without departing from the scope and spirit of the appended claims.

Having thus described my invention what I claim is:

1. In combination with an infants high chair including legs, seat section and a back, of an auxiliary seat member, said seat member having a substantially fiat bottom face adapted to engage with the upper face of said seat section, said member being formed with a downwardly and rear wardly sloping upper face, means for pivotally connecting the rear portion of said seat member to said seat section, whereby said member may be elevated relative thereto, said seat member being adapted to receive and support an infant thereon whereby his knees will be raised and his weight will be shifted rearwardly to his hips so that the latter will be positioned and retained against the back of said chair.

2. In combination with an infants high chair including legs, substantially horizontal seat section and a back, of an auxiliary seat member, said seat member having a substantially flat bottom face adapted to engage with the upper face of said seat section, said member being formed with a downwardly and rearwardly sloping upper face, said upper face having a concave area thereon, means for pivotally and removably connecting the rear portion of said seat member to said seat section whereby said member may be elevated relative thereto, said seat member being adapted to receive and support an infant thereon whereby his knees will be raised and his weight will be shifted rearwardly to his hips so that the latter will be positioned and retained against the back of said chair.

3.
