1. A seat system for a vehicle, the seat comprising:
a substantially vertical support constructed and arranged for attachment to a wall of the vehicle; seat components comprising:
a back member for supporting an occupant's back when in use,a base member, comprising a front edge and a back edge, the base member being for configuration in a first condition where the base member extends generally perpendicularly from the back member and is suitable for accommodating an occupant in a sitting position, and being for configuration in a second condition where the base member is retracted and thereby tends to reduce a profile of the seat, anda side member; a seat element including a seat chassis for supporting the seat components; and an attachment comprising:
a first link extending from a first pivot joint on the side member of the seat chassis to a first pivot joint on the base member, anda second link extending from a second pivot joint on the same side member of the seat chassis as the first link to a second pivot joint on the base member, wherein the first and second links, the base member and the seat chassis thereby provide a four bar linkage, the first and second links of the four bar linkage being configured to connect the base member to the seat chassis such that the base member may be selectively configured between the first condition and the second condition, wherein selectively configuring from the first condition to the second condition will cause the base member to rise at the back edge with respect to a point on the at least one side member, and dip at the front edge of the base member with respect to the point on the at least one side member, wherein said seat element is slidably mounted in a substantially vertical direction along said substantially vertical support. |
