Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat for the driver's seat and/or passenger's seat of a motor vehicle, particularly a passenger car.

Conventionally, in an automobile, particularly in a passenger car, a driver's seat and/or a passenger seat, which are comprised of a seat and a backrest, the seat as a whole is movable forward and backward with respect to the body, or in addition to this, the backrest is inclined relative to the seat, etc.
Various types are already known.

However, in general, the driver's seat of a passenger car is narrow, especially in the case of a small car.
Even if the backrest is sufficiently tilted rearward, it is still often difficult to sit in the driver's seat or passenger seat. This is especially true for the driver's seat, where the steering wheel protrudes toward the seat, but it is also a problem that often occurs in the passenger seat, especially when women are wearing Japanese or formal clothes. .

The present invention is based on the conventional automobile driver's seat and/or
In view of the above-mentioned difficulties in the seat for the passenger seat, the object of the present invention is to provide a seat for the driver's seat and/or passenger's seat that can eliminate such difficulties.
That is the purpose.

In order to achieve this objective, the present invention connects the seat and frame of the driver's seat and/or passenger's seat through an annular sliding and rotating member so that they can rotate relative to each other. Freely,
The vehicle is characterized in that the seat can normally be locked in a direction parallel to the longitudinal axis of the vehicle.
