Abstract

PURPOSE:To enable a seat to turn to a meeting position allowing a driver to easily ride on, by a method wherein a seat is automatically rotated and moved forward and backward in linkage with opening and closing of a vehicle door through the working of a seat moving device. CONSTITUTION:A vehicle seat is so constituted that it is rotatable and movable forward and backward through a seat rotating device 40 and a seat moving device 50, which are mounted to a seat cushion part 10. When a door is opened for a driver to ride on, after a seat E is automatically moved forward and backward to a rotatable range through the working of a control device by means of a door releasing signal, the seat is rotated to a meeting position allowing the driver to easily ride on. Thereafter, when the driver seats, the seat is automatically returned to its original position through the working of the control device by means of a seating signal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the improvement of vehicle seats, and is applied to driver and/or passenger seats of automobiles.

[Technical background of the invention and its problems]

2. Description of the Related Art In recent years, some vehicles, such as passenger cars, have rotatable seats in order to make it easier for drivers to get on and off the vehicle.

However, with this type of conventional seat, when getting on and off, the seat had to be manually rotated in a direction that facilitates getting on and off.

In other words, with conventional seats of this type, even when the door is opened in order to board the vehicle, the seat is not automatically rotated to a pick-up position where the user can easily board, and the user manually rotates the seat. Furthermore, when exiting the vehicle, even if the door is opened, the seat does not automatically rotate to a position that makes it easy for the user to exit the vehicle, and the user must manually rotate the seat. did not become.

[Purpose of the invention]

The present invention was developed as a result of studies to solve the above-mentioned problems.
It has been achieved.

Therefore, the first object of the present invention is that when a user opens the door to board a vehicle, the seat automatically moves back and forth to a rotatable range and then rotates to a pick-up position where it is easy for the user to sit down. When exiting the vehicle, the seat automatically returns to its original position, and when the door is opened, the seat automatically moves back and forth as far as it can rotate, and then rotates to a position where it is easy to exit the vehicle. Furthermore, it is an object of the present invention to provide a vehicle seat in which the seat automatically returns to its original position when the door is closed after getting off the vehicle.

A second object of the present invention is to provide a vehicle which is capable of automatically returning to an optimum driving posture pre-stored in a control device when the user (driver) sits down, for example when the seat is a driver's seat. The purpose is to provide seating.

A third object of the present invention is to provide a vehicle seat in which the height of the headrest can be automatically adjusted.

[Structure of the invention]

That is, the present invention provides a vehicle seat comprising a seat cushion part, a seat back part provided on one side of the seat cushion part so as to be removable, and a headrest provided on one side of the seat back part. , the seat is configured to be rotatable via a seat rotation device, and configured to be movable back and forth via a seat movement device, so that it automatically rotates and/or moves back and forth in conjunction with opening and closing of the vehicle door. The gist of this article is the characteristic vehicle seat.

[Embodiments of the invention]

Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.

1 to 5 show a vehicle seat according to an embodiment of the present invention, FIG. 1 is a partially cutaway perspective view showing the overall structure, and FIG. 2 is a partially cutaway view showing the seat rotation device. FIG. 3 is a cutaway side view explanatory view, FIG. 3 is a partially cutaway front view explanatory view showing the seat back part, and FIGS. 4 and 5 are part views showing the seat back part, the headrest, and the automatic lifting device for the headrest. FIG. 3 is a cutaway side view explanatory diagram.

In the figure, E denotes a vehicle seat according to an embodiment of the present invention, which includes a height-adjustable seat cushion part IO, a seat bank part 20 tiltably provided on one side of this seat part 10, and a seat bank part 20 that is tiltably provided on one side of this seat part 10. It is comprised of a headrest 30 provided on the top of the back part 20 so as to be movable up and down.

The vehicle seat E includes a seat rotation device 40 and a seat movement device 5 provided in the seat cushion portion 10.
0, it is configured to be able to rotate and/or move back and forth, and when a user opens the door (not shown) to board the vehicle, the control device (not shown) is activated by the door open signal.
After the seat E automatically moves back and forth to the rotatable range, it rotates to the pick-up position where it is easy to board the vehicle.When the user sits down, the seat E automatically When returning to the original position and exiting the vehicle, an operation switch (not shown) was operated to open the door, and the operation signal from the operation switch automatically moved seat E back and forth to the rotary range via the control device. After that, the seat E is rotated to a position where it is easy to exit the vehicle, and when the door is closed after exiting the vehicle, the seat E is automatically returned to its original position via the control device in response to this door closing signal.

Further, the seat back portion 20 has a seat back tilting motor 6 mounted on one side of the attachment portion to the seat 27932 portion IO.
1, the inclination angle of the seat bank portion 20 can be automatically adjusted via the control device according to the user's preference, and the inclination angle can be adjusted according to the user's preference. If this is stored in the control device, the user can automatically return to the memorized optimal posture when he or she sits down.

Moreover, as described above, since the inclination angle of the seat bank portion 20 can be automatically adjusted, the seat E automatically moves and rotates to a pick-up position where it is easy to board the vehicle in conjunction with the opening of the door when boarding the vehicle. At this time, depending on the inclination angle of the seat back part 20, when the seat E rotates, there is a risk of collision with the seat bank part of an adjacent seat.
The inclination angle of the seat back portion 20 can be automatically corrected in conjunction with the rotation and/or longitudinal movement of the seat E.

Furthermore, the headrest 30 is equipped with an automatic lifting device 70, and is configured such that the height of the headrest 30 can be automatically adjusted via a control device.

Further, the seat shoe ring portion 10 includes a seat shoe 9.
