Abstract
The embodiments described and claimed herein are improved wheelchair passenger securement systems and stations. In particular, one embodiment described and claimed herein is a drop-in system comprising a barrier module and a wall-side module, which incorporate three separate restraint devices which are configured to secure a wheelchair at three separate attachment points. The system can optionally include a moveable excursion barrier or a pull-mechanism to pre-tension at least one of the restraint devices the wheelchair securements. In a simpler embodiment, three restraint devices, such as retractors, are provided for attachment to the vehicle surfaces or structures in, for example, a generally right-triangular configuration.
