A telescopic access ramp 1 for a vehicle (100), the access ramp comprising: a frame 13; a first ramp section 12a coupled to the frame; a second ramp section (12b) coupled to the first ramp section; first and second ramp deployment mechanisms 2, 3 configured to drive the first and second ramp sections, respectively, between stowed and deployed configurations with respect to the second ramp section and the frame, respectively, wherein the movement of the second ramp section by the second deployment mechanism drives the operation of the first deployment mechanism. The ramp sections may move simultaneously. The first deployment mechanism may include panel drive arm(s) (23) moveable along a path defined by a panel guide member (22) which moves with the second ramp section, wherein the drive arm carries rollers (233) which engage a base guide member (21), which may have guiding formations (221, 211, 212) to control the rate of movement of the first section, and to assist in movement of the panel drive arm(s). The second deployment mechanism may define slots configured to receive, and constrain the movement of, the rollers. |
