Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a regress of a seat used in a vehicle, an airplane or the like, and particularly a state where the seat is stored in a leg portion of the seat and needs to be pulled out when the seat is used. It is related to the regress to use.

(Prior Art) For seats of vehicles and aircraft, especially seats of aircraft,
People often have to stay seated for long periods of time. Therefore, a so-called reclining seat has been developed in which the sitting posture, especially the angle of the backrest can be changed appropriately. However, since it is not possible to take a comfortable posture simply by changing the angle of the backrest, seats have been developed in which the position where the feet are placed can be freely changed.

As a seat in which the position where the foot is placed can be freely changed, there is proposed a seat in which a rotating arm is attached to the seat or a seat located in front of the seat and the rotating arm is provided with a foot, that is, a regressor. There is.

However, in such a footrest, since the footrest position is fixed, it is not possible to meet various demands of all persons. In particular, when it is difficult to leave the seat for a long time, such as when traveling by air, not only sitting on the seat but also extending the body and legs to sleep and sleeping as described above. It is not enough to mount the foot in such a structure. That is, in the case of a regress in a seat that is used for a long time such as a seat of an airplane, it is necessary to sufficiently satisfy the following various conditions.

When not in use, the regress should not itself occupy the space around the seat. This is because it interferes with the person sitting in the seat or a person passing through the aisle.

The regress must have sufficient space to rest or reposition the foot. By changing the position of the legs placed on the regress, it becomes possible to spend more comfort.

It is necessary for the regress to have its height and angle freely changeable. This is because it is possible to spend more comfort by freely changing the angle and position of the legs placed on the regress.

The regress should be easy to use when in use. This is because it is used by an unspecified number of people.

When the regress is high, the foot support from it must be strong.

The inventors of the present invention are completely unaware of a regression that satisfies all of these conditions. Therefore, to develop a regressor that satisfies all of the above conditions,
As a result of earnest studies by the inventors, the inventors have newly discovered that all of the above conditions can be satisfied by properly combining the link mechanisms, and completed the present invention.

(Problems to be Solved by the Invention) The present invention has been made based on the above experience,
The problem to be solved is the absence of solving the necessary conditions in the conventional type of regress.

An object of the present invention is to provide a seat regressor that can solve all of the above-mentioned conditions (1) to (4) with a simple configuration.

A more specific object of the present invention is that it can be completely stored in the legs when not in use so that it does not get in the way of going in and out of the seat, and the operation when using is very easy. The object is to provide a seat regressor with a simple configuration that can be used by anyone without requiring a simple explanation, and that the use angle can be freely selected.

A further detailed object of the present invention is to provide a seat regressor capable of achieving a structure capable of sufficiently withstanding a load during use with a small number of parts.

(Operation and Mode of Use of the Invention) Next, the function of the seat regress (100) according to the present invention configured as described above will be described in detail together with the mode of use thereof.

First, the basic movement of the seat regress (100) according to the present invention will be described with reference to FIGS. 1 to 4.
When this seat regress (100) is not used, as shown in FIG. 1, the seat regress (100) is completely contained in the storage part (220) of the leg (210) forming the seat (200). It is in a stored state. In such a state, there is nothing extra protruding around the seat (200), so the person sitting in the seat (200) or the passage near the seat (200) should be The seat regress (100) according to the present invention does not interfere with a passerby at all.

Next, when the user wants to use the seat regress (100) according to the present invention, as shown by the seat (200) on the right side in FIG. It is put out in front of the leg (210). In each of the following embodiments according to the present invention, the seat regress (10
0) is taken out by operating an operation section (250) provided inside or on the upper surface of the armrest plate (240) forming the seat (200). That is, the operating section (250) operates, for example, the drive motor (11) provided on the rear upper surface of the base (10) shown in FIG. 5, and the driving force from the drive motor (11) is used. Is a rack (2 that is laid inside the storage section (220) via a reducer or transmission (12).
It is transmitted to the pinion (13) that engages with (30).
The pinions (13) are a pair of left and right, and either the pinion (13) is transmitted to the driving force of the drive motor (11) or the rotation direction is changed to move the base (10) forward or backward. It is set to retreat.
As a result, the entire seat regress (100) is moved forward from the storage section (220) of the leg section (210) and stored.

As for the seat regress (100) which is projected in front of the leg portion (210) in this way, the user installs it inside the armrest plate (240) constituting the seat (200) or on the upper surface or the like. By operating the operation section (250), for example, as shown in FIG. 14, the legrest body (60) of the seat legrest (100) is brought into a substantially horizontal state suitable for resting the user's foot. To do. The order in which the seat legrest (100) according to the present invention becomes a state suitable for resting such a foot will be schematically described with reference to FIGS. 2 to 4.

2 to 4, the seat regress (10
The structure of (0) is shown in a simplified manner, and the base (10) and the main body (60) of the regressor (60) constituting the seat regress (100) are shown.
A support frame (62) that is a part of the first link mechanism (20) and the second link mechanism (30) that operatively connect the base (10) and the support frame (62). The drive device (50) for driving the first link mechanism (20) and the second link mechanism (30) is shown. The state of FIG. 2 shows the state in which the seat regress (100) is stored in the storage portion (220) of the leg portion (210) or the state where the seat retreat (100) is taken out from the storage portion (220). The first link mechanism (20) and the second link mechanism (30) are in a folded state, so that the support frame (62) of the regress main body (60) is the base (10). It is placed on the top and is in a thin state as a whole so that it can be stored in the storage portion (220) of the seat (200).

From this state, the user operates the operation unit (250) to operate the drive device (50), and the second shaft (33) in the base (10) is moved to the right in the drawing. As a result, first, the lower end of the first arm (31) of the second link mechanism (30) is moved to the right, and the first arm (31) is supported by the second arm (32). Thus, the first arm (31) rises. As a result, the support frame (62) of the regress main body (60) is at the rear end (right end in FIG. 3).
Rises, the regress part (61) of the regres body (60)
The upper surface of the seat is substantially aligned with the upper surface of the seat (211).

It is possible to rest your feet on this condition, but if you want to keep the regress part (61) of the regress main body (60) in a horizontal state, continue to operate the operation part (250). Seat Regression (100) No. 4
The horizontal state is as shown in the figure.

In order to bring the seat regress (100) into the horizontal state of FIG. 4, it is sufficient for the user to continue to operate the operation section (250) as described above, and by doing so, the drive device (50).
By this, the second shaft (33) in the base (10) is further moved to the right in the drawing. As a result, the right end of the second shaft (33) shown in the figure is located at the lower end of the second arm (22) that constitutes the first link mechanism (20) (in the embodiment, this second arm (22) Since the contact roller (26) provided is pressed to the right in the figure, the second arm (22) is thereby moved to the first shaft (23).
At the same time, it rotates counterclockwise in the figure with respect to the base (10). Along with this rotation, the first arm (21) connected to the second arm (22) pushes up the front end portion (left end portion in the drawing) of the support frame (62) of the regress main body (60). In this case, the rear end of the support frame (62) has the first link mechanism (20).
Since the support frame (62) is supported by the support frame (62), the front end of the support frame (62) rises to bring the support frame (62) into a horizontal state as shown in FIG.

The operation during this time will be described in more detail as follows. First, it is the screw shaft (52) shown in FIG. 5 that is directly moved back and forth by the drive device (50). This screw shaft (52) is rotatable with respect to the second shaft (33). It is connected to the connected connector (40). Therefore, when this connecting body (40) pulls the second shaft (33) by the movement of the screw shaft (52),
Since the second shaft (33) is integral with the second arm (32),
The second shaft (33) slightly rotates with respect to the connecting body (40). That is, the second shaft (33) is the drive device (50).
The guide member (15) provided on the base (10) side by the operation of
It moves back and forth while slightly rotating in the long hole (16).

Then, when the second shaft (33) retracts by a certain amount (moves to the right in the drawing), the second shaft (33) moves the contact roller provided on the support arm (24) on the first link mechanism (20) side. It contacts (26) and pushes it to the right in the figure. The support arm (24)
Since it is rotatably connected to the base (10) by the first shaft (23), it rotates counterclockwise about the first shaft (23). Therefore, the front end of the support frame (62) is moved upward by the first arm (21) which is integrated with the support arm (24) via the first shaft (23).

At this time, the guide claw (35) is integrally fixed to the second shaft (33) at the same position as the contact roller (26) on the first link mechanism (20) side. ) Tip of the contact roller (26) provided on the support arm (24) on the side of the first link mechanism (20) while rotating by the rotation accompanying the retreat of the second shaft (33). I will touch and scoop this up. As a result, the second arm (22) on the side of the first link mechanism (20)
While the movement of the second arm (22) is restricted by the contact between the contact roller (26) and the guide claw (35) so that the movement of the second arm (22) follows the movement of the guide claw (35). Axis (33)
It can be lifted little by little as it moves.

Finally, when the front end of the support frame (62) has completely moved up, the engagement recess (25) provided in the second arm (22) on the first link mechanism (20) side moves. Second link mechanism (3
While being fitted to the second shaft (33) on the 0) side, the engaging groove (34) provided on the guide claw (35) on the second link mechanism (30) side is fitted into the first groove on the first link mechanism (20) side. The single shaft (23) is fitted. Thus, when the regressing body (60) is lifted by the first link mechanism (20) and the second link mechanism (30), the first shaft (23) and the second link mechanism on the side of the first link mechanism (20). The second shaft (33) on the (30) side includes the engaging groove (34) of the guide claw (35) on the second link mechanism (30) side and the second arm (22) on the first link mechanism (20) side. The recessed body (60) is fitted and supported in the engaging recesses (25), and the regress main body (60) is firmly supported with respect to the base (10).

Of course, if the reverse operation to the above is performed, the seat regress (100) according to the present invention will be the seat (200) on the left side in FIG.
As in the above, it is completely stored in the storage portion (220).

In the embodiment of the present invention, the drive source of the drive device (50) that operates the second shaft (33) is a drive motor that can rotate in both directions, and the direction in which the operation unit (250) is pushed is changed. By changing the driving direction of the drive motor, it is possible to appropriately select the driving direction, and at the position where the driving of the drive motor is stopped, the seat regress (10
