Abstract

Abstract A mechanism for raising and lowering a seat, especially designed for handicapped persons, comprises two supporting arms (A', B') which are both at one of their ends coupled to the seat (E), at the front and rear edge thereof, respectively. At their other end, the supporting arms (A', B') cooperate with a fixed point (1', 2') each. At least one of the supporting arms is coupled to a driving member and the two supporting arms (A', B') are interconnected at a point between their ends. With a view to obtaining a space-saving but all the same stable mechanism allowing a physiologically correct trajectory of the seat during its raising and lowering, the supporting arms (A', B') are directly pivotally interconnected (D), and one of the supporting arms cooperates with the fixed point in such a manner that it is displaceable in relation to said point.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 111 words
A mechanism for raising and lowering a seat, comprising two supporting arms (A', B') which have one end coupled to the seat (E)-at the front and rear edges respectively of the seat, and have their other ends co-operating with respective fixed points, one at least of the supporting arms being coupled to a driving member (I, N) and the two supporting arms (A', B') being interconnected at a point between their ends, characterized in that the supporting arms (A', B') have a direct pivotal interconnection (D), and in that one of the supporting arms is mounted for guided translational movement in relation to the fixed point (2') associated with that arm.
Claim 2
Dependent Claim 111 words
A mechanism for raising and lowering a seat, comprising two supporting arms (A', B') which have one end coupled to the seat (E)-at the front and rear edges respectively of the seat, and have their other ends co-operating with respective fixed points, one at least of the supporting arms being coupled to a driving member (I, N) and the two supporting arms (A', B') being interconnected at a point between their ends, characterized in that the supporting arms (A', B') have a direct pivotal interconnection (D), and in that one of the supporting arms is mounted for guided translational movement in relation to the fixed point (2') associated with that arm.
Claim 3
Dependent Claim 42 words
A mechanism according to claim 1, characterized in that said one of the supporting arms is connected to the associated fixed point (2') through a radius arm (F) pivotally coupled to said one supporting arm (B') and to the fixed point (2').
Claim 4
Dependent Claim 46 words
-A mechanism according to claim 1, characterized in that one of the fixed points (2") is constituted by a sliding bearing (13) wherein the supporting arm (B') cooperating with this fixed point or a part coupled to said arm is accommodated in a longitudinally sliding manner.
Claim 5
Dependent Claim 34 words
A mechanism according to claim 3, characterized in that the driving member (I) is coupled to both of the arms (A', B',) and arranged to move the arms in opposite directions to each other.
