Multipanel rollstops mountable on the outboard end of a wheelchair lift platform in which at least one upper panel of the rollstop folds down or telescopes to reduce the rollstop profile for stowage. Preferred embodiments include bifold, trifold or telescoping rollstops for underfloor or under vehicle lifts. In the extended multipanel position, rollstops of the invention provide increased rollstop height and occupant security in the intermediate and transfer positions of the lift as compared to non-folding or telescoping rollstops of the same stowage profile. The folding of telescoping of the rollstop is automatic upon lift stowage. In a preferred embodiment, the rollstop upper panel is folded or unfolded by a direction-reversing mechanical actuator through a contact arm which engages structure of the lift or stowage compartment, and operates automatically without requiring operator intervention. In the unfolded, deployed safety barrier configuration the top edge of the rollstops of the invention extend at least 7'' above the platform, which is the critical minimum to stop a runaway wheelchair event.
