Expandable seat for a vehicle
An expandable seat for a vehicle comprising a support structure movable between an expanded state and a contracted state, the support structure forming a seating region that is greater in size when the support structure is in the expanded state than when the support structure is in the contracted state, and a flexible covering movably coupled to the support structure. The support structure and the flexible covering cooperate to ensure that the flexible covering covers the seating region of the support structure when the support structure is in the expanded state and when the support structure is in the contracted state.
1. An expandable seat for a vehicle, comprising:
a support structure movable between expanded and contracted states and forming a seating region that is greater in size when in the expanded state than in the contracted state, wherein the support structure tapers laterally;
a flexible covering movably coupled to the support structure, the support structure and the flexible covering cooperating to ensure that the flexible covering covers the seating region of the support structure when the support structure is in the expanded state, and in the contracted state; and
a carrier assembly coupling a free end of the flexible covering to the support structure and allowing the free end of the flexible covering to move relative to the support structure as the support structure moves between the expanded state and the contracted state.
2. The expandable seat according to claim 1 , wherein the expandable seat is configured to seat a plurality of occupants when the support structure is in the expanded state.
3. The expandable seat according to claim 1 , wherein the support structure is configured to expand laterally.
4. The expandable seat according to claim 1 , wherein the support structure comprises a body portion and at least one other portion that is movably coupled to the body portion to cause the support structure to expand.
5. The expandable seat according to claim 1 , wherein the support structure is movable between a first state where the seating region is planar and a second state where the seating region is contoured.
6. The expandable seat according to claim 1 , wherein the support structure comprises at least one bearing element configured to aid the movement of the flexible covering relative to the support structure.
7. The expandable seat according to claim 1 , wherein the flexible covering is configured to wrap around a lateral edge of the support structure.
8. The expandable seat according to claim 1 , wherein the carrier assembly is configured to movably couple a free end of the flexible covering to an underside of the support structure.
9. An expandable seat for a vehicle, comprising:
a support structure movable between expanded and contracted states and forming a seating region that is greater in size when in the expanded state than in the contracted state;
a flexible covering movably coupled to the support structure, the support structure and the flexible covering cooperating to ensure that the flexible covering covers the seating region of the support structure when the support structure is in the expanded state, and in the contracted state;
a carrier assembly coupling a free end of the flexible covering to the support structure and allowing the free end of the flexible covering to move relative to the support structure as the support structure moves between the expanded state and the contracted state; and
a plurality of support ribs arranged longitudinally across the seating region.
10. The expandable seat according to claim 9 , wherein the plurality of support ribs are more closely grouped when the support structure is in the contracted state.
11. The expandable seat according to claim 9 , wherein at least one of the plurality of support ribs is moveably coupled to the support structure.
12. The expandable seat according to claim 9 , wherein at least one of the plurality of support ribs is fixed to the support structure.
13. The expandable seat according to claim 9 , wherein the flexible covering comprises at least one of the plurality of support ribs.
14. The expandable seat according to claim 9 , wherein at least one of the plurality of support ribs is trapezoidal in cross section.
15. An expandable seat for a vehicle, comprising:
a support structure movable between expanded and contracted states and forming a seating region that is greater in size when in the expanded state than in the contracted state;
a flexible covering movably coupled to the support structure, the support structure and the flexible covering cooperating to ensure that the flexible covering covers the seating region of the support structure when the support structure is in the expanded state, and in the contracted state; and
a carrier assembly coupling a free end of the flexible covering to the support structure and allowing the free end of the flexible covering to move relative to the support structure as the support structure moves between the expanded state and the contracted state, wherein the carrier assembly is configured to movably couple a free end of the flexible covering to an underside of the support structure.
16. The expandable seat according to claim 15 , wherein the expandable seat is configured to seat a plurality of occupants when the support structure is in the expanded state.
17. The expandable seat according to claim 15 , wherein the support structure is configured to expand laterally.
18. The expandable seat according to claim 15 , wherein the support structure comprises a body portion and at least one other portion that is movably coupled to the body portion to cause the support structure to expand.
19. The expandable seat according to claim 15 , wherein the support structure is movable between a first state where the seating region is planar and a second state where the seating region is contoured.
