Description

  The present invention relates to a reclining seat return positioning structure, and in particular, when the reclining seat is rotated, when the pedal is stepped on, the backrest portion returns to the vertical position and the backrest portion returns to the vertical position. Even if it is not positioned without it, the backrest part automatically returns to the vertical position by stepping on the pedal, so that the reclining seat can be prevented from being affected by the rotation space and unable to rotate the reclining seat. It relates to a positioning structure.

Generally, reclining seats installed on high-speed railways, trains, and the like can adjust the backrest portion to an appropriate inclination angle in order to make sitting comfort more comfortable. In addition, adjacent front or rear seats can be rotated 180 degrees so that they can face each other and the seats can face each other.
However, in the conventional reclining seat, the structure for adjusting the angle of the backrest portion and the structure for rotating the seat are controlled separately, so that when the seat is rotated, the backrest portion is returned to the vertical position for positioning. If the forgetting is forgotten, the rotation space is affected, the reclining seat cannot be rotated, or the reclining seat is damaged.

  In light of the shortcomings of the prior art, the inventor of the present invention is able to make the rotation operation of the reclining seat more convenient from the experience, unremitting research and experiments that have been engaged in the technology for many years. Invented the structure.

  The main purpose of the present invention is that when the reclining seat is rotated, if the pedal is stepped on, the backrest part will return to the vertical position and the pedal will not be positioned even if the backrest part returns to the vertical position. The backrest automatically returns to the vertical position when stepped on, so that the reclining seat can be prevented from being affected by the rotation space and the reclining seat can be operated more conveniently. It is to provide a return positioning structure.

  In order to solve the above-described problem, the reclining seat return positioning structure of the present invention includes a fixed base and a sheet that rotates along the fixed base. The seat is provided with a seat portion and a backrest portion that are connected to each other. A hydraulic cylinder is provided at the lower edge of the backrest. One end of the hydraulic cylinder is fixed to the seat, and the other end is fixed to the backrest. The hydraulic cylinder is connected to a pedal provided on a side edge of the fixed base and an operating lever provided on an armrest of the seat via a wire.

  The pedal is provided on the fixed base. By providing a spring between the fixed base and the pedal, when the foot is released from the pedal, the spring is returned and positioned.

  With the reclining seat return positioning structure of the present invention, the user can tilt the backrest backward and adjust the comfortable tilt angle by controlling the hydraulic cylinder with the armrest operating lever. Also, when rotating the reclining seat, when the pedal is depressed, the hydraulic cylinder is controlled and the backrest part returns to the vertical position, and even when the backrest part returns to the vertical position and is not positioned. Since the backrest portion automatically returns to the vertical position by stepping on, it is possible to prevent the rotation space from being affected, the rotation space from being affected, and the reclining seat from being unable to rotate.

It is a perspective view which shows this invention. It is a perspective view which shows the wire of this invention. It is a disassembled perspective view which shows the pedal of this invention. It is a perspective view which shows the operation state of this invention.

Please refer to FIG. FIG. 1 is a perspective view showing the present invention. FIG. 2 is a perspective view showing the wire of the present invention. FIG. 3 is an exploded perspective view showing the pedal of the present invention.
As shown in FIGS. 1 to 3, the present invention includes a fixed base 1 and a seat 2 that rotates along the fixed base 1. A positioning groove 21 is provided on one side of the sheet 2. The seat 2 is provided with a seat portion 22 and a backrest portion 23. The rear edge of the seat portion 22 and the backrest portion 23 are connected to each other via an interlocking rod 24 to form a movable structure. The seat 2 is provided with a hydraulic cylinder 3 (in this embodiment, two hydraulic cylinders 3 are provided).
One end of the hydraulic cylinder 3 is fixed to the seat 2, and the other end is fixed to the backrest 23. The hydraulic cylinder 3 is connected to a pedal 4 provided on the side edge of the fixed base 1 via a wire 31 and connected to an operating lever 26 provided on an armrest 25 of the seat 2 via a wire 32.

  The pedal 4 is provided on the seat body 41. The seat body 41 is fixed to the fixed base 1. A spring 42 is provided between the seat body 41 and the pedal 4. As a result, when the foot is released from the pedal 4, the spring 42 is returned and positioned. A wire 31 is connected to the other end of the pedal 4. The pedal 4 is provided with a circular engaging portion 43. Thereby, when the pedal 4 is not stepped on, the engaging portion 43 is engaged with the positioning groove 21 of the seat 2 by the elastic force of the spring 42.

By combining the above-described members, the reclining seat return positioning structure of the present invention is configured. When the pedal 4 is not stepped on, the engaging portion 43 of the pedal 4 is engaged with the positioning groove 21 of the seat 2, so that the seat 2 cannot be rotated. When the user controls the hydraulic cylinder 3 with the operating lever 26 of the armrest 25, the backrest 23 can be tilted backward.
When rotating the reclining seat, when the pedal 4 is depressed, the engaging portion 43 of the pedal 4 is disengaged from the positioning groove 21 of the seat 2 and the reclining seat can be rotated 180 degrees, and the hydraulic cylinder 3 is controlled, The backrest 23 is returned and positioned vertically. As a result, when the pedal 4 is depressed, the backrest portion 23 automatically returns to the vertical position, so that even if the backrest portion 23 does not return to the vertical position and is not positioned, the rotational space is affected and the reclining seat cannot be rotated. Can be prevented.

FIG. 4 is a perspective view showing an operating state of the present invention. As shown in FIGS. 2 to 4, since the engaging portion 43 of the pedal 4 is engaged with the positioning groove 21 of the seat 2 when the user is seated, the seat 2 is positioned and does not rotate. In this state, when the user operates the operating lever 26 of the armrest 25, the hydraulic cylinder 3 is controlled via the wire 32, and the backrest 23 can be tilted to a comfortable angle.
Further, when the reclining seat is rotated, when the pedal 4 is depressed, the engaging portion 43 of the pedal 4 is released from the positioning groove 21 of the seat 2. In this state, the sheet 2 can be rotated 180 degrees along the fixed base 1. When the pedal 4 is stepped on, the wire 31 controls the hydraulic cylinder 3, and the backrest 23 is returned to the vertical position. Thus, when the reclining seat is rotated, even when the backrest portion 23 returns to the vertical position and is not positioned, the backrest portion 23 automatically returns to the vertical position by stepping on the pedal 4. It is possible to prevent a collision and damage.

  The above-described embodiment shows a preferred embodiment of the present invention, and does not limit the scope of the present invention. Modifications and changes within the scope of the present invention are included in the present invention.

The reclining seat return positioning structure of the present invention is configured by combining a seat part and a back part connected to each other, a hydraulic cylinder connected to the back part, and a pedal for controlling the hydraulic cylinder.
Accordingly, when the reclining seat is rotated, when the pedal is depressed, the hydraulic cylinder is controlled so that the backrest portion returns to the vertical position and the pedal 4 is returned even when the backrest portion returns to the vertical position and is not positioned. Since the backrest portion 23 automatically returns to the vertical position by stepping on, it is possible to prevent the rotation space from being affected and the reclining seat from being unable to rotate, thereby making the operation of the reclining seat more convenient. . That is, the present invention is highly practical and unique.
