  • Cushion for anatomical support, especially for the lumbar and cervical regions, to fit onto seat backs
    Patent number: 5567011
    Abstract: Cushion (50) for anatomical support, especially of the lumbar and cervical regions, for mounting onto backs (42) of seats (41) generally, includes a curved elastic plate (51) having longitudinal ends connected by a posterior brace formed by a pair (55, 60) of rods threaded in opposite directions and screwed into an intermediately placed cylindrical scroll (63) so that it is possible to vary the convexity of the plate (51) and therefore the extent to which the cushion projects from the seat back (42) by rotation of the scroll (63) in one direction or the other. It is also possible to adjust the height of the cushion, when placed inside the seat back (42), by a special internal mechanism (51, 71, 72, 74) operated by a knob (45) placed on the outside. Furthermore, an electric ratio motor can be provided to drive the cylindrical scroll rotatably. A three position switch can be connected between a source of power and the ratio motor to drive the motor in either of two rotation directions or not at all.
