Abstract
Abstract A swivellable seat for a motor vehicle having a seat bearing on which a seat is mounted for rotation about a vertical swivel axis. The seat bearing is itself carried by a cantilevered support arm having a hinge attachment to a door pillar of the vehicle body such that the seat can be swung from a stowed position inboard of the vehicle to an outwardly projecting position outboard of the vehicle body, thereby facilitating access to the seat by disabled persons.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A swivellable seat for a motor vehicle comprising: a seat bearing for supporting a seat for rotation about a swivel axis, said seat bearing including a bearing plate concentric with the swivel axis and a swivel plate attachable to the seat and resting upon said bearing plate for rotation relative thereto about said swivel axis, a cantilevered support arm mounted at one end thereof to said bearing plate of said seat bearing and including a hinge at the other end thereof for mounting to a door pillar of the vehicle body so that said cantilevered support arm is pivotal about a hinge axis substantially parallel to and spaced from said swivel axis and is movable angularly about the hinge axis between a first position in which said seat bearing is inboard, corresponding to a stowed positon of the seat, and a second position in which said seat bearing is outboard of a door opening of the vehicle, and a third position in which the seat bearing is outboard of the vehicle and displaced rearwardly relative to the door opening.
Claim 2
Dependent Claim
