Wheelchair passenger securement system with movable bumper
View Patent ↗The embodiments described and claimed herein are improved wheelchair passenger securement systems and stations. In particular, one embodiment described and claimed herein is a system that includes a wheelchair restraint and a moveable bumper, wherein the movable bumper is configured to induce tension into the wheelchair restraint.
1. A securement system adapted for securing a mobility aid in a vehicle, the securement system comprising:
a restraint and a bumper;
whereby the restraint is adapted to extend between and attach to the vehicle and the mobility aid for securing the mobility aid during transit; and,
the bumper is adapted as a touch point between the vehicle and the mobility aid for restraining the mobility aid during transit;
wherein the bumper is movable between a first position and a second position, whereby, in its first position, the bumper is spaced a first distance from the mobility aid and, in its second position, the bumper is spaced a second distance from the mobility aid; and,
the bumper is adapted to induce tension in the restraint when moved from the first position to the second position.
2. The securement system of claim 1 , wherein the bumper is adapted to be in close proximity to the mobility aid in the second position.
3. The securement system of claim 2 , wherein the bumper is adapted to be touching the mobility aid in the second position.
4. The securement system of claim 1 further comprising a bumper mechanism, wherein the bumper mechanism is adapted to move the bumper between the first position and the second position.
5. The securement system of claim 1 , wherein the second distance is greater than or equal to null.
6. The securement system of claim 1 , wherein the bumper exerts a force on the mobility aid when moved from the first position to the second position to induce tension in the restraint.
7. A securement system adapted for securing a mobility aid in a vehicle, the securement system comprising:
a restraint and a bumper;
whereby the restraint is adapted to extend between and attach to the vehicle and the mobility aid for securing the mobility aid during transit; and,
the bumper is adapted as a touch point between the vehicle and the mobility aid for restraining the mobility aid during transit;
a bumper mechanism, wherein the bumper mechanism is adapted to move the bumper between a first position and a second position, whereby, in its first position, the bumper is spaced a first distance from the mobility aid and, in its second position, the bumper is contacting the mobility aid; and,
wherein the bumper is adapted to induce tension in the restraint when moved from the first position to the second position.
8. The securement system of claim 7 , wherein the bumper exerts a force on the mobility aid when moved from the first position to the second position to induce tension in the restraint.
9. A securement system adapted for securing a mobility aid in a vehicle, the securement system comprising:
a first mobility aid restraint, a second mobility aid restraint, a bumper, and a tensioning mechanism that are configured to cooperate to resist movement of the mobility aid;
whereby the first mobility aid restraint is adapted to extend between and attach at one end to the vehicle and at the other end directly to the mobility aid for securing the mobility aid during transit;
the first mobility aid restraint comprises a first retractor and the second mobility aid restraint comprises a second retractor, wherein the first and second retractors are self-tensioning;
the first mobility aid restraint is angled slightly upward with the one end being at a lower elevation than the other end, whereby the first mobility aid restraint is adapted to exert a downward force on the mobility aid;
the bumper is not directly attached to the mobility aid, is adapted as a touch point between the vehicle and the mobility aid for restraining the mobility aid during transit, and is adapted to be positioned at least partially between the first retractor and the second retractor;
the tensioning mechanism is adapted to induce tension into the first mobility aid restraint, whereby the first mobility aid restraint exerts a force on the mobility aid in a direction at least partly toward the bumper;
at least one module, wherein at least one of: (a) the first mobility aid restraint, (b) the second mobility aid restraint, and (c) the bumper are fixed to the at least one module; and,
the tensioning mechanism is fixed to the bumper.
