Abstract
First and second plate members mounted upon a vehicle seat include a selectively inflated pneumatic chamber positioned therebetween, whereupon actuation of a remote pneumatic pump effects inflation of the chamber, thereby pivoting the first plate relative to the second plate to enhance a directing of an individual from the vehicle seat.
Claims6
A vehicle pneumatic seat lift apparatus for use with a vehicle seat having a base portion, the apparatus comprising:
- a first plate having a first plate hinge side and a first plate top wall, said first plate being arranged for mounting upon said base portion;
- a second plate having a second plate hinge side and a second plate bottom wall, said second plate bottom wall having a recess directed into said second plate bottom wall;
- a hinge for pivotally coupling said first plate hinge side to said second plate hinge side and permitting a pivoting of said first plate relative to said second plate, such that the second plate bottom wall is in contiguous communication with the first plate top wall in a first position, and the second plate bottom wall is displaced relative to the first plate top wall in a second position;
- a pneumatic chamber mounted within said recess, said recess permitting said pneumatic chamber to reside therewithin, thereby permitting a contiguous positioning of said first plate top wall against said second plate bottom wall when said apparatus is in said first position;
- a pneumatic pump, the pneumatic pump including an on/off switch and a power supply means for coupling the pump to a power source, with the pneumatic pump arranged in a remote, separated orientation relative to the pneumatic chamber;
- and,
- a pneumatic conduit in pneumatic communication with the pneumatic pump and the pneumatic chamber.
