Stowable cantilevered seat

摘要

A stowable seat for mounting to a support member of a vehicle and for use next to a preexisting obstruction wherein a space may be selectively provided for positioning a wheelchair article adjacent to the stowed seat which includes a frame attached to the support member (floor), a cantilevered seatbase and a seatback. The cantilevered seatbase has a free end, a linked end associated along a path generated arc with the frame for providing the seatbase with a range of motion that avoids the obstruction even when moved from a horizontally deployed position to a substantially vertical stowed position. For additional stability a diagonal support truss supports the seatbase in the deployed position with a movable end of the support truss sliding within a runner track and a fixed end journalled with the frame working in combination with said linked end defining the vertical and lateral motion of the seatbase. The seatback is rotatably associated with the seatbase and has a range of motion extending from an unfolded position to a folded where the seatback in the unfolded position can be adapted to be at a predetermined angle with respect to the seatbase in said deployed position to provide seating and the seatback in the folded position can be adapted to fold flat against the seatbase for stowing to provide the space for the wheelchair.
