Disclosed is a hinge for a buggy, stroller, etc. for infants. The hinge includes a first hinge member and a second hinge member. Hinge member includes a first hinge end and a connecting end to connect to a first structural member of an infant support apparatus along a first axis. The second hinge member includes a hinge end and a connecting end to connect to structural member of the infant support apparatus along a second axis. The hinge members are pivotal about an axis between a bent condition wherein the first and second longitudinal axes are non-aligned and a straight condition wherein the first and second longitudinal axes are generally aligned. The hinge ends are configured such that the amount of the profiles which overlap prevent the formation of a finger trap.

A hinge as claimed in claim 1, wherein the second hinge end portions are disposed at the ends of the hinge in the transverse direction so that each first hinge end portion moves within adjacent second hinge end portions. 3. A hinge as claimed in claim 1, wherein each said hinge end is asymmetric about the pivot axis and the hinge ends are generally diametrically opposed in the first condition and generally contiguous in the second condition. 4. A hinge as claimed in claim 1, wherein adjacent first and second hinge end portions have respective planar surfaces which slide against each other during pivotal movement thereby providing support against loading on the hinge. 5. A hinge as claimed in claim 4, wherein mutually opposing planar surfaces at least partially overlap in the first condition thereby providing support against loading when the hinge ends are non-aligned. 6. A hinge as claimed in claim 5, wherein overlapping between mutually opposing planar surfaces increases when in the second condition thereby providing increased support against loading when the hinge ends are aligned. 7. A hinge as claimed in claim 1, wherein the hinge end portions between the end profile portions have a width in the transverse direction of less than 5 mm. 8. A hinge as claimed in claim 1, comprising a locking mechanism for locking the hinge in the second condition. 9. A hinge as claimed in claim 8, wherein said locking mechanism is spaced inwardly from an outer surface of the profile of the hinge members to prevent finger trapping. 10. A hinge as claimed in claim 8, wherein said locking mechanism comprises a hook pivotally mounted relative to the first hinge end and a detent located in the second hinge end, wherein the hook engages with the detent to lock the hinge. 11. A hinge as claimed in claim 10, wherein a cable extends from the hook to a handle which allows the hook to be released from the detent remote from the hinge. 12. A hinge as claimed in claim 1, wherein the hinge ends comprise respective stop portions which abut against each other in the first condition to stop pivotal movement in the first pivotal direction; and wherein the profile of the hinge ends have an outer configuration which prevents finger trapping between said stop portions when said hinge members are pivoted in the first pivotal direction from said first condition to the second condition. 13. A hinge as claimed in claim 12, wherein the profile of the first said hinge end comprises one of said first hinge end portions located between two second hinge end portions of the profile of the second hinge end such that the first and second hinge end portions are provided alternately in the transverse direction; and a first said stop portion is formed by said first hinge end portion and a second said stop portion is formed between the second hinge end portions. 14. A hinge as claimed in claim 13 wherein at least two of said first hinge end portions comprise respective said first stop portions which abut against a plurality of said second stop portions between second hinge end portions. 15. A hinge as claimed in claim 12, wherein the first said stop portion comprises a hook and the second stop portion comprises a bar extending between second profile portions. 16.
