A collapsible support frame for an infant pushchair having a seat, the support frame comprising
- an elongate central spine, the central spine including a foldable first spine member and a foldable second spine member,
- the foldable first spine member including a rigid first subsidiary spine member and a rigid second subsidiary spine member, the second subsidiary spine member being pivotably coupled to the first subsidiary spine member, and a rigid third subsidiary spine member, the third subsidiary spine member being pivotably coupled to the second subsidiary spine member,
- the foldable second spine member including a rigid fourth subsidiary spine member, a rigid fifth subsidiary spine member pivotably coupled to the fourth subsidiary spine member, and a rigid sixth subsidiary spine member pivotally coupled to the fifth subsidiary spine member,
- the first subsidiary spine member of the first spine member being pivotably coupled to the fourth subsidiary spine member of the second spine member, the second subsidiary spine member of the first spine member being pivotably coupled between a first end and a second end thereof and forming a pivot joint with the fifth subsidiary spine member of the second spine member, the pivot joint being located at an intersection between the second subsidiary spine member and the fifth subsidiary spine member, and the third subsidiary spine member of the first spine member being pivotably coupled to the sixth subsidiary spine member of the second spine member,
- a handle assembly coupled to a first end of the central spine, and
- a coupler attached to a second end of the central spine,
- whereby the central spine is movable between an elongate erect configuration, and a collapsed configuration wherein the subsidiary spine members are generally adjacent one another.
