Seat with tipping seating portion for vehicles, in particular for railway vehicles

摘要

A seating portion includes a support structure (10); a tipping seating portion (2), movably connected to the support structure to move between an open position and a closed position. At least one movable armrest (31, 32) is movably connected to the support structure to move between an open position and a closed position. A rotation device moves the seating portion from the open position to the closed position. The armrest (31, 32) is kinematically connected to the seating portion so that the armrest is moved from the position of use to the position of non-use by the movement of the seating portion from the position of use to that of non-use.

1. A seat with tipping seating portion for vehicles, comprising:
a support structure, destined to be anchored to a vehicle; a tipping seating portion, movably connected to the support structure to move between a position of use and a position of non-use, in which the seating portion is positioned leaning against the support structure to reduce the overall space occupied by the seat; at least one movable armrest, movably connected to the support structure to move between a position of use and a position of non-use, in which the armrest is positioned leaning against the support structure to reduce the overall space occupied by the seat; means for moving the seating portion from said position of use to said position of non-use, the armrest being kinematically connected to the seating portion so that the armrest is moved from the position of use to the position of non-use by movement of the seating portion from the position of use to the position of non-use; wherein the seating portion is connected to the armrest by kinematic connection means, which, when the seating portion moves from the position of use to the position of non-use, drag the armrest in rotation from the position of use towards the position of non-use; wherein the kinematic connection means are structured to create a one-way constraint between the seating portion and the at least one armrest such that the armrest placed in the position of use, is concerned only by the movement of the seating portion from the position of use to the position of non-use, so as to make the armrest kinematically independent of the seating portion, when the armrest is in the position of non-use or when the seating portion moves from the position of non-use to the position of use; wherein the kinematic connection means comprise a non-rigid connection element; and wherein the non-rigid connection element is connected at a first end to the seating portion and at a second end to the armrest in an offset position from the second rotation axis, the non-rigid connection element being positioned in relation to the armrest and to the seating portion in such a way that the non-rigid connection element is tensioned, moving the armrest in rotation, only when the seating portion moves from the position of use to that of non-use.
