A vehicular seat for handicapped and elderly persons is disclosed which is readily accommodated in any type of conventional vehicle, such as automobile, van, bus and the like. The vehicular seat is given three degrees of freedom of movement, the first degree being a rotary one in a horizontal plane about a shiftable vertical axis of rotation, the second being a rectilinear one in a horizontal plane, and the third being rotary in a horizontal plane about a fixed vertical rotary axis. The three degrees of freedom allow for angular positioning of the seat proper relative to the ajar door, so as to ensure minimal interference between the person being seated and the frame and ajar door of the vehicle. The seat proper is provided with a pair of leg rests, each being independently maneuverable and locked in place by a manually-rotatable lever detent which has a lower end having an arcuate cut-out portion for receiving therein one detent rod of a plurality of parallel detent rods, each rod spanning the width of the rear surface of the leg rest to position each leg rest at a desired pivotal orientation.

A vehicular seat for handicapped and elderly persons, comprising, in combination: a seat proper having a bottom portion; first means operatively connected to said seat proper for mounting said seat proper for rotation about a first vertical pivot axis; said first means comprising a carriage mounted for reciprocal movement, and also comprising a pivot means upstanding from said carriage rotatably mounting said seat proper for rotation about said first vertical pivot axis; second means mounting said carriage for reciprocal movement, said second means comprising a horizontal track means; said carriage of said first means having means for guided movement along said said track means so as to define a horizontally-shiftable first vertical pivot axis; third means for rotatably mounting said track means of said second means for rotation about a second vertical pivot axis; said third means comprising an upstanding pivot shaft defining said second vertical pivot axis, said pivot means being laterally movable relative to said pivot shaft to thereby define an adjustable, eccentric rotation of said seat proper relative to said upstanding pivot shaft, so that said seat proper may be angularly adjusted to the position of the open door of the vehicle, and also be adjusted so that, depending upon its position along said track means, its position relative to the opening of the door of the vehicle may be changed and preset; said upstanding pivot shaft and said pivot means being substantially in axial co-linear alignment for normal uses of said seat proper when said seat proper is positioned within the vehicle and not projecting outwardly of the vehicular door, so that said pivot shaft and pivot post rotate as one unit without eccentric rotation of said seat proper; means for selectively and fixedly positioning said seat proper in a desired relative rotational orientation with respect to said track means, whereby said seat proper may be rotated relative to said carriage means and said track means to orient said seat proper at any desired angular position with respect to said track means; and means for mounting the lower portion of said pivot shaft to the frame of the vehicle to which said seat proper is to be mounted.
