ABSTRACT:
An interactive seating device such as a stool or chair which makes it possible for an individual to sit down without having to lower himself to do so, the seated individual being thereafter assisted in getting up from the seat. The device includes an articulated seat whose front segment is hinged to a rear segment and is so linked thereto that in a perching mode in which the rear segment is at an elevated level and the front segment is folded down, an individual can then perch on the rear segment without having to lower himself. The rear segment is mounted on a depressible spring mechanism supported on a stand that normally raises the seat to the perching mode level. When the individual perches on the rear segment, the resultant load imposed thereon depresses and thereby energizes the spring mechanism, causing the seat to sink to a sitting mode level at which the front segment is outstretched to fully support the seated individual. And when the individual thereafter seeks to get up from the seat, he is assisted in doing so by the energized spring which then urges the seat to return to the perching mode level.
