Abstract

PURPOSE:To facilitate easy getting on and off by turning at least a seat section of a seat unit of a car toward the opening direction of a door only by a preset angle. CONSTITUTION:When a passenger gets on and off a seat for a car with a door 5 open, a seat section 2 in a displaced position is turned toward the opening direction of the door 5 within 110 deg., as compared with a seat 1 in a fixed position. In this case, the seat back section 3 of the seat is kept in the fixed position and at least only the seat sections 1 and 2 are rotated. In addition, the rotation of the respective seat sections 1 and 2 is performed by, for example, expanding and contracting a free arm 6 according to the opening and closing of the door 5 and connecting them to one end of the free arm 6 and moving them until they can be hooked with each of stoppers 8 and 9 that fix a pin 7 fixed at the lower part of the respective seat sections 1 and 2 to the floor surface of a car body. As a result, getting on and off the respective seat sectins 1 and 2 is faciltated.

Traditionally, car seats have been fixed, and even when they are movable, they only slide slightly afterward to set the optimal driving position, and when getting in or out of the car, one has to shift one's body sideways or twist one's body to change the orientation. I needed to hatch it.

ることによって充分な効果が得られる。FIG. 1 is a top view showing that the packet seat in the front seat rotates, and 1 shows the seat in its normal position when driving, and 2 shows the seat rotated toward the door 5 when getting out of the vehicle. At this time, it is possible to have a structure in which the backrest portion 3 shown by the broken line also rotates at the same time, but in this case, it is necessary to have a mechanism in which the seat does not rotate unless the backrest is returned from the backward leaning position when traveling to the upright position 14. be. Generally, as shown in Figure 1, a sufficient effect can be obtained by leaving the backrest part 3 as it is and rotating only the seat part 1.2, which makes contact with the buttocks and the large part of the body and takes most of the body weight. It will be done.

も採用できる。The rotational center point X does not necessarily have to be the center of the seat, but should be appropriately determined depending on the ease of getting on and off the seat, how the weight is applied, etc. Further, the seats 1.2 are not necessarily held by a single rotating shaft. For example, a thin mechanism such as a thrust bearing that distributes the weight and stops the bearing can be used.

戻る例を示した。FIG. 2 is a top view of a bench-type seat mainly used as a rear seat. The easiest seat shapes to use as a rotating seat include a and bXc. In a and b, the rotation center point X is located at the center of the circular rotating part. In case of C, the center of rotation X is located slightly closer to the door, and when getting on and off the seat moves slightly outward during driving, making it easier to get on and off. d and e show examples in which the center of rotation moves along a dotted line trajectory when rotating the seat so that the rotating seat surface can be rotated while keeping it close to a square. That is, in d, as the seat rotates, the center of rotation moves from the X position to the 7 position, reaches the position shown by the broken line, that is, the 7 position at the stage of 45 degree rotation, and returns to the X position again after 90 degree rotation. Indicated.

ｄの方式と同じである。This movement of the center of rotation can be achieved by using a slide groove at the bottom of the seat, or by cutting a plurality of grooves in the upper and lower parts in the trajectory direction and interposing a ball between them. In the case of e, the center of rotation during traveling is at the X position, and the seat is at 9
When rotated 0 degrees, it moves to the 2nd position. The movement of the center of rotation is the same as in method d.

。In the rotating seat according to the present invention, depending on the shape of the rotating part or the setting position of the rotation center point, a part of the seat may extend outside beyond the inner line when the door 5 is closed. Then, by providing a mechanism that works with the door to return the seat to position I when the vehicle is in motion when the door is closed,
Contact between the inside of the door and the seat portion can be prevented.

する。Figure 3 shows the simplest example of the interlocking mechanism, with door 5
When the door 5 is closed, the free arm 6 attached to the door 5 presses the bin 7 attached to the bottom of the seat 1 as the door 5 closes, returning the seat to its normal position while driving and setting the pin 7 on the floor. The sheet 1 is fixed by being sandwiched between the stopper 8 made of hard rubber or other material.

る。The seat 2 shows the state when the door 5 is opened.The pin 7 attached to the seat 2 can freely slide in the groove at the tip of the free arm 6, so when the door 5 is opened, the seat 2 can rotate freely. However, the rotatable angle of the seat 2 is limited by the stopper 9 installed on the floor.

。In the example shown in the drawings, the seat is assumed to rotate 90 degrees for convenience, but the rotation does not need to be 90 degrees in order to make getting on and off the vehicle easier. Particularly when the wheel portion is located at the lower part of the rear side, such as in the rear seat of a passenger car, the rotation angle is naturally limited, but if it is 30 degrees or more, getting on and off becomes very easy.
