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, when the door is opened to board the vehicle, the seat is not automatically rotated to a pick-up position where the user can easily board, but rather the seat is manually rotated by the user. Furthermore, when exiting the vehicle, even if the door is opened, the seat is not automatically rotated to a position that makes it easy for the user to exit the vehicle, and the user must manually rotate the seat himself. There wasn't.

Therefore, the inventor of the present invention proposed that when a user opens the door to board the vehicle, the seat automatically moves back and forth through the control device based on this signal to a rotatable range, and then rotates to the pick-up position where it is easy to board the vehicle. On the other hand, when the user sits down, this seating signal automatically returns the seat to its original position via the control device, and when the user gets out of the car, the door can be opened by operating the operating switch. The seat automatically moves back and forth through the control device based on the operation signal of E
We have developed a vehicle seat that automatically returns to its original position.

The present invention is linked to the opening and closing of the vehicle door, and the seat back portion is stored in advance in the control section. ! The above-mentioned seat rotation effect can be improved by making it automatically actuated depending on the posture.
