Abstract: A folding safety helmet intended primarily for use by a cyclist has a top panel (10) and a pair of similar side panels (11, 12), each panel (10, 11, 12) being made of a plastics material. Each side panel (11, 12) is separately pivoted at its two ends to the end regions (16, 17) of the top panel (10) and a pair of straps (13, 14) is arranged to limit the relative separation of the side panels with respect to the top panel. The side panels (11, 12) may be moved between an opened-out configuration where the helmet is ready for wear, and a folded position where the majority of the side panels lies within the confines of the top panel (10), so greatly reducing the volume of the helmet and facilitating its storage when not in use.

Abstract: A collapsible two wheeled vehicle comprises a substantially rigid main structural frame (10) defining a head section (16), a saddle pillar mount (17) and a bottom bracket (15). A rear wheel sub-frame (22) is pivoted to the frame (10) about the bottom bracket (15), and carriers a rear wheel (23), the sub-frame (22) being arranged for movement between a folded position where the rear wheel lies within the frame, between the head section (16) and the saddle pillar mount (17), and an active position where the sub-frame projects rearwardly beyond the frame. A pedal arrangement (19, 20, 21) is journalled in the bottom bracket (15) and drives the rear wheel (23) through an endless chain (25).
