Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mechanism for obtaining a complete reclining of a seat, in particular an aircraft seat.
[0002]
More particularly, the invention relates to a mechanism of the above type capable of creating a "bed" condition in a tightly confined space.
[0003]
The solution provided by the present invention is particularly public for "business" class seats.
[0004]
[Prior art]
It is well known that aircraft are equipped with seats for Economic Class, Business Class, and often First Class.
[0005]
A number of technical solutions have been studied for maximum comfort, especially for the business class and the first class. While it is easy to find a solution for First Class due to the large space available, it is more difficult to get some results with Business Class seats. It is clear.
[0006]
More specifically, it is not easy to obtain a "bed" condition, mainly because the space available in business class is small.
[0007]
The solution provided by the present invention is included in this regard.
[0008]
[Problems to be solved by the invention]
In particular, it is a primary object of the present invention to provide a mechanism for fully reclining a seat until it is in a bed with a minimum of space.
[0009]
It is another object of the present invention to provide a solution of the above type which can be a "bed" without discontinuities in the plane where the passenger rests.
[0010]
Yet another object of the invention is to provide a mechanism which is very simple from a structural point of view, while at the same time being easy and reliable.
[0011]
It is yet another object of the present invention to provide a technical solution that eliminates the presence of visible guides.
[0012]
[Means for Solving the Problems]
It is therefore a special object of the present invention to provide a lower member fixed substantially to the floor, which is arranged substantially in a rear position, provided with a guide, and a backrest portion and a seat seat are provided at a rear portion and a front portion, respectively. In front of the lower member, a seat member on which a swing lever member is pivotally supported above the lower part thereof, and a rear end portion pivotally supported at a connection point between the seat member and the backrest portion, A seat member, in particular, an aircraft seat seat, further comprising an actuation means for actuating a swinging lever member to actuate the entire mechanism for reclining or lifting the seat, the lever comprising a lever member pivotally supported at the front end. This is a mechanism for obtaining a complete reclining function.
[0013]
According to the present invention, there is provided a lifting mechanism for a seat footrest.
[0014]
Furthermore, according to the present invention, each sheet can be provided with two different mechanisms.
[0015]
Further, according to the present invention, the swing lever operating means can be constituted by mechanical, liquid pressure operated, pneumatically operated, liquid and pneumatically operated operation means.
[0016]
In a preferred embodiment of the mechanism according to the invention, the seat member is provided at the rear with two means for the backrest part and two connection points for the connection of the seat, namely an upper point and a lower point, respectively.
[0017]
The present invention is described below according to preferred embodiments, with particular reference to the accompanying drawings, which are intended to be illustrative and not limiting.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Referring to the accompanying drawings, FIGS. 1 and 2 show a seat back 1 and a seat 2 with a footrest 2 ', as well as other parts of the mechanism according to the invention.
[0019]
In particular, said mechanism comprises fixing points 4, 5 for fixing the lower bar of the seat to the floor, and a member 3 with a guide 6, the function of which according to the invention is described in the following description. Will be obvious.
[0020]
The seat member 7 is pivotally supported at points 8 ', 9' on the backrest portion 1 at locations indicated by reference numerals 8 and 9 at the rear, and the member 7 is seated at locations corresponding to locations 10 and 11. 2 Further, the member 7 is slidable along the guide 6 of the member 3 at the rear portion provided with the pin 12 ′.
[0021]
The front rocker lever 12 is provided at the bottom and front of the member 3 and is connected in coincidence with the points 13, 13 'and is a hydraulic, pneumatic, liquid and pneumatic actuator. Actuating device 14 acts on the swing lever.
[0022]
The rocking lever 12 is further pivotally supported at a point indicated by reference numeral 15 with respect to a point 15 ′ of the member 7.
[0023]
A connecting lever 16 is further included, which is pivoted at its rear end at the point 9-9 ′ and the other whole 8 at the point 18 ′ of the rocking lever 12.
[0024]
3a to 3e, the operation of the mechanism according to the invention can be seen.
[0025]
Activating the actuating device 14 causes the pivoting lever 12 to rotate on the lower member 3 around the pivot point 13.
[0026]
The pivoting lever 12 moves forward with respect to the seat, and thus pushes the seat member 7 forward at the pivot points 15, 15 'and moves forward by the movement of the connecting lever 16 along the guide 6 of the lower member 3.
[0027]
The movement of this mechanism continues until the "bed" position of FIG. 3e is obtained.
[0028]
In the embodiment shown, this solution requires only one mechanism for reclining the seat, but a dual mechanism according to the invention is provided for each seat.
[0029]
At the same time, the footrest 2 'is lifted in view of the conventional mechanism, but will not be described further since the footrest is not a special purpose of the present invention.
[0030]
In the embodiment shown in the accompanying drawings, the seat comprises further structural features which are the subject of another patent application filed on the same date, in particular when the rear body 19 is opened and the seat seat is opened during reclining operation. To be able to move.
[0031]
It is further provided with a panel 20 which, when opened, allows more space for the shoulder.
[0032]
If desired, a lowerable arm 21 is further provided in order to obtain a continuous space with the adjacent seat.
[0033]
Although the present invention has been described by way of non-limiting example in accordance with preferred embodiments, those skilled in the art will appreciate that modifications and / or improvements may be made without departing from the scope of the claims set forth below. You must understand that changes can be made.
