Abstract

PURPOSE: To provide a rotary seat rotatable so that the passenger always turns in the running direction. CONSTITUTION: The seat comprises a fixed frame 24 fixed to the vehicle floor through a support 28 and a movable frame 22 to the top of which chairs 11, 11' are fixed, the movable frame 22 is pivoted onto the fixed frame 24 so as to take two positions 180 deg. apart from each other with center at a vertical pivot 32 disposed on a symmetric plane P to the two chairs, and the fixed frame 24 extends underneath one chair 11 slightly beyond the symmetric plane P to the two chairs while the other chair 11' is a cantilever to the fixed frame.

Detailed Description of the Invention

[0001]

[Industrial application] Some railway vehicles are equipped with seats that allow the passengers to pivot about a vertical axis so that the passengers are always facing the direction of travel.

2. Description of the Related Art Patent Nos. 1,045,190 and 1,1
No. 30,837 and No. 1,213,877 include a fixed frame fixed to a floor of a vehicle by a support, and a movable frame fixed to a top of a chair, the movable frame including two movable frames. A two-chair seat, of the type that is pivotably mounted on the fixed frame so as to take two positions 180 ° apart from each other around a vertical pivot located in the plane of symmetry of the chair, especially for rail cars. It is known.

In addition, there are fixing elements which engage one another at the corners of the two frames so as to fix them and prevent vibration or inadvertent rotational movement of the chairs. Furthermore, this structure comprises a locking device.

[0004]

In these known seats, the fixed frame extends along the entire length of the two chairs. However, this involves two major problems as described below. -If the movable frame is provided with attachments that reach below the level of the fixed frame, e.g. with footrests used by passengers sitting in the back seat of their seat, these must be You have to lift the accessories. If these precautions are not taken, these accessories may collide with the fixed frame and
It will hinder rotation to the 80 ° position.

-Because the seats are symmetrical, said fastening elements are visible to the passengers in the rear seats. This is because the fixing element must be exposed above the fixing frame during the rotational movement of the seat.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a two-chair seat of the above-mentioned type in which the fixed frame extends below one chair and the plane of symmetry of both chairs. Extending slightly beyond, the other chair provides a revolving seat that is cantilevered with respect to a fixed frame.
Thus, the lower space of the other chair is completely freed and the seat can be pivoted without lifting the footrest or any other downwardly depending accessory. In addition, this structure can be provided with locking means not visible from the rear for locking the seat in one of two positions.

[0007]

The present invention will now be described in detail with reference to the embodiments shown in the drawings, but the present invention is not limited thereto. 1 and 2, two chairs 1 for a rail car
A swivel seat 10 consisting of 1, 11 'is shown schematically. Each chair comprises a seat 2, a mottle 14 and an armrest 16 in a manner known per se. These chairs are symmetrical with respect to the vertical plane P.

The seat is installed transversely to the traveling direction of the vehicle, and one side surface of the seat is arranged adjacent to the partition 20 of the vehicle. As is known per se, the seat comprises a movable frame 22 consisting essentially of a rectangular plate.
Sticked on. This frame 22 is the floor 26 of the vehicle
It is pivotally mounted on a fixed frame 24 connected to the.

The stationary frame 24 is cantilevered and therefore includes a horizontal cantilever beam 30. In the embodiment of FIG. 1, the beam 30 is supported by a vertical support 28 secured to the partition 20 or floor 26. The seat 10 is pivotally mounted about a vertical pivot 32 mounted at the end of the beam 30 opposite the partition 20. The pivot 32 is fixed to the movable frame 22 at a plane of symmetry P.

Due to such a structure, the chair on the side opposite to the partition 20 (chair 11 'in this case) has a cantilever structure with respect to the horizontal beam 30. One advantage of such a construction is that the horizontal beam 30 pivots from one position to the other when the movable part of the seat is provided with an appendage extending below the level of the horizontal beam 30. It does not interfere with the pivoting movement of the seat. In FIG. 1, a footrest 34 is illustrated as an example of such an accessory, but the footrest is fixed to the rear portion of the seat for use by a passenger sitting in the rear seat. When the seat is rotated in the f direction from the positions shown in FIGS. 1 and 2, the footrest is a horizontal beam 3
Does not interfere with 0.

Therefore, the seat can freely rotate 180 ° to the position shown by the broken line in FIG. In the above-mentioned known seat, a horizontal beam extends below the two chairs. Therefore, in order to prevent the footrest from colliding with the beam 30, the footrest had to be lifted toward the motares. According to the present invention, such consideration is unnecessary.

As shown in FIGS. 3 and 4, the pivot 32 is shown.
Consists of a substantially cylindrical member with a flange 36 at its upper end through which the pivot 32 is fixed to the movable frame 22 by means of bolts 38 or similar. Beam 30 at the bottom of the pivot
Is pivotally mounted in a cylindrical hole 40 in a pedestal 42 secured to the end of the. The pivot 32 is provided with a holding means (not shown) so as not to be pulled out by an upward pulling force. Stop means (not shown) are provided for locking the seat in either of its two operating positions.

The present invention is not limited to the above description, but can be arbitrarily modified and implemented within the scope of the gist thereof. For example, the beam 30 can be supported by one or more legs, rather than being cantilevered.
