A child carrier frame includes a lower frame, an upper frame and a frame support. The frame may be adjusted between an upright position, for use, and a folded position. During folding, the carrier frame may be adjusted both to reduce its height and its width, such that a folded size is obtained that is smaller in at least two dimensions than a similar carrier frame folded to reduce only one of its height and width.

What is claimed is: 1. A child carrier frame comprising a lower frame including at least a lower left side member and a lower right side member, an upper frame including at least an upper left side member and an upper right side member, a height spacing defined between the lower frame and the upper frame, a width spacing defined between the lower and the upper left side members and their respective right side members, a height adjustment pivotal connection acting between the upper frame and the lower frame to permit at least one of the upper frame and the lower frame to pivot to adjust the height spacing and a width adjustment pivotal connection to permit at least one of the lower left side member and the lower right side member to pivot and at least one of the upper left side member and the upper right side member to pivot to adjust the width spacing and a frame support to support the lower frame and the upper frame and to control pivoting of the height adjustment and the width adjustment pivotal connections, the frame support is selected such that movement thereof inwardly between the upper frame and the lower frame drives both a reduction in height spacing and a reduction in width spacing. 2. The child carrier frame of claim 1 wherein the frame support includes a collapsible frame between the lower left side member and the lower right side member. 3. The child carrier frame of claim 1 wherein the frame support includes a collapsible frame between the upper left side member and the upper right side member. 4. The child carrier frame of claim 1 wherein the frame support includes a collapsible frame pivotally connected to the lower left side member, the lower right side member, the upper left side member and the upper right side member. 5. The child carrier frame of claim 4 wherein the collapsible frame includes pivotal connections to the lower left side member, the lower right side member, the upper left side member and the upper right side member at least some of which permit rotation about at least two axis axes. 6. The child carrier frame of claim 4 wherein the collapsible frame includes a center component, upper region members pivotally connected between the upper frame and the center component, lower region members pivotally connected between the lower frame and the center component. 7. The child carrier frame of claim 6 wherein the center component is connected such that movement thereof drives rotation about both the width adjustment pivotal connection and the height adjustment pivotal connection. 8. The child carrier frame of claim 6 wherein the frame support prevents over-rotation between the center component and the upper region members and prevents over-rotation between the center component and the lower region members such that a reduction in height spacing and a reduction in width spacing is achieved only by moving the center component forwardly between the upper frame and the lower frame. 9. The child carrier frame of claim 1 further comprising a connector connected between the upper frame and the lower frame and on which the height adjustment pivotal connection and the width adjustment pivotal connection are positioned. 10. The child carrier frame of claim 9 wherein the connector is positioned at a forward end of the frame. 11. The child carrier frame of claim 9 wherein the height adjustment pivotal connection includes an upper pivotal connection between the connector and the upper left side member and an upper pivotal connection between the connector and the upper right side member and the upper pivotal connections permit the upper frame to be folded down towards the lower frame. 12. The child carrier frame of claim 11 wherein the width adjustment pivotal connection includes a lower pivotal connection between the connector and the lower left side member and a lower pivotal connection between the connector and the lower right side member and the lower pivotal connections selected to permit the lower left side member and the lower right side member to be moved toward and away from each other. 13. The child carrier frame of claim 12 wherein the width adjustment pivotal connection further includes the upper pivotal connections further selected to permit the upper left side member and the upper right side member to be moved toward and away from each other. 14. The child carrier frame of claim 1 wherein the frame support includes a pivotal connection permitting rotation about at least two axes. 15. The child carrier frame of claim 14 wherein the pivotal connection permitting rotation in at least two axes is a universal joint between the frame support and the upper frame. 16. A child carrier frame comprising a lower frame including at least a lower left side member and a lower right side member, an upper frame including at least an upper left side member and an upper right side member, a height spacing defined between the lower frame and the upper frame, a width spacing defined between the lower and the upper left side members and their respective right side members, a height adjustment pivotal connection acting between the upper frame and the lower frame to permit at least one of the upper frame and the lower frame to pivot to adjust the height spacing and a width adjustment pivotal connection to permit at least one of the lower left side member and the lower right side member to pivot and at least one of the upper left side member and the upper right side member to pivot to adjust the width spacing and a frame support to support the lower frame and the upper frame and to control pivoting of the height adjustment and the width adjustment pivotal connections, the frame support including a pivotal connection permitting rotation about at least two axes and wherein the pivotal connection permitting rotation in at least two axes is a universal joint between the frame support and the upper frame. 17. The child carrier frame of claim 16 wherein the frame support includes a collapsible frame between at least one of (a) the lower left side member and the lower right side member and (b) the upper left side member and the upper right side member. 18. The child carrier frame of claim 16 wherein the frame support includes a collapsible frame pivotally connected to the lower left side member, the lower right side member, the upper left side member and the upper right side member. 19. The child carrier frame of claim 18 wherein the collapsible frame includes a center component, upper region members pivotally connected between the upper frame and the center component, lower region members pivotally connected between the lower frame and the center component. 20. A child carrier frame comprising a lower frame including at least a lower left side member and a lower right side member, an upper frame including at least an upper left side member and an upper right side member, a height spacing defined between the lower frame and the upper frame, a width spacing defined between the lower and the upper left side members and their respective right side members, a height adjustment pivotal connection acting between the upper frame and the lower frame to permit at least one of the upper frame and the lower frame to pivot to adjust the height spacing and a width adjustment pivotal connection to permit at least one of the lower left side member and the lower right side member to pivot and at least one of the upper left side member and the upper right side member to pivot to adjust the width spacing and a frame support to support the lower frame and the upper frame and to control pivoting of the height adjustment and the width adjustment pivotal connections, the frame support including a collapsible frame pivotally connected to the lower left side member, the lower right side member, the upper left side member and the upper right side member and including a center component, upper region members pivotally connected between the upper frame and the center component, lower region members pivotally connected between the lower frame and the center component and wherein the center component is connected such that movement thereof drives rotation about both the width adjustment pivotal connection and the height adjustment pivotal connection. 21.
