Device for the movement of resting components of a sofa, a chair and the like
The present invention relates to a device for the movement of resting components of a sofa, an armchair or the likes, such as a headrest movable between a lowered position and a raised position, a back movable between a substantially erected configuration and a downwardly inclined configuration, a seat movable between a backward position and a forward position, and a footrest movable between a lowered, substantially vertical position and a raised position. Such a device comprises a telescopic member equipped with a movable portion controlled by a motor and able, jointly with further connection members, to place in reciprocal relation and to move said headrest, back, seat and footrest.
1. A device for moving resting components of a sofa, an armchair or the like, including a headrest movable between a lowered position and a raised position, a back movable between a substantially erected configuration and a downwardly inclined configuration, a seat movable between a backward position and a forward position, and a footrest movable between a lowered substantially vertical position and a raised position, said device comprising a telescopic member equipped with a movable portion controlled by a motor and capable of, jointly with a plurality of connection members, to reciprocally move said headrest, back, seat and footrest; said telescopic member being movable between three different configurations: a first configuration of minimal extension of the movable portion in which the footrest is in its lowered position, the seat is in its backward position, the back is in its substantially erected configuration and the headrest is in its lowered position; a second configuration of partial extension of the movable portion in which the footrest is in its lowered position, the seat is in its backward position, the back is in its substantially erected configuration and the headrest is in its raised position; and a third configuration of maximum extension of the movable portion, in which the footrest is in its raised position, the seat is in its forward position, the back is in its downwardly inclined configuration and the headrest is in its raised position.
2. The device according to claim 1 , wherein the telescopic member is able to rotate about a fixed fulcrum in relation to said device structure.
3. The device according to claim 1 , wherein the plurality of connection members comprise a hinged mechanism connected to the back and to the headrest.
4. The device according to claim 3 , wherein the plurality of connection members comprise a flexible element connected to the movable portion and to the hinged mechanism by means of respective joints.
5. The device according to claim 4 , further comprising at least one through-hole to guide the movement of the flexible element.
6. An armchair or sofa comprising the device according to claim 1 .
