Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat used for example in an automobile, and more particularly to a structure for providing a comfortable holding feeling and a relaxing feeling when seated.

In general, in order to provide a comfortable sitting experience for automobile seats, a sense of hold is created by undulating the seating surfaces of the seat cushion, which supports the buttocks of the occupant, and the seat back, which constitutes the backrest. A feeling of relaxation is created by adjusting the angle of the backrest of the seat.

By the way, the hold feeling and the relaxing feeling are generally contradictory to each other in sitting comfort, and thus the holding feeling and the relaxing feeling have conventionally been provided by separate mechanisms.

The purpose of this invention is to divide the seat cushion and the seat bag into a main part and a side part, respectively, in view of the conventional situation mentioned above, and to make the main part of the seat bag retract as the main part of the seat cushion moves forward. The step formed between the main part and the side part creates a holding feeling, and as the main part of the seat cushion moves back, the main part of the seat back protrudes and the main part and the side part are separated. To provide a vehicle seat that can create a feeling of relaxation by making it substantially flush.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Details of embodiments of the sheet according to the present invention will be described below with reference to the drawings. Although this embodiment has been exemplified with respect to a rear seat of an automobile, the present invention is not limited thereto, and can also be applied to a seat for seating one person, such as a front seat of an automobile.

FIG. 1 is a perspective view of the seat of the present invention, which includes a seat cushion 1 for receiving the buttocks of a seated person, and a seat back 2 standing upright at the rear of the seat cushion 1 and forming a backrest.
The seat cushion 1 and the seat back 2 form a bench-like structure on which a plurality of occupants can sit side by side. Said seat cushion 1
The seat back 2 is divided into main parts 3, 4 and side parts 5, 6 located on both sides of the main parts 3, 4, and the tops of the side parts 6 of the seat back 2 form a bridge in the vehicle width direction. entwined,
A headrest 8 is attached to the top of each bridge portion 7.

On the other hand, the main portion 3 of the seat cushion 1
As shown in the second figure, a slide mechanism 9 is interposed between the seat cushion 1 and the installation surface L,
By operating a lever (not shown) of the slide mechanism 9, each main portion 3 can freely reciprocate in the front-rear direction of the vehicle. The slide mechanism 9 is provided for each main section 3, and is provided for each main section 3 in a parallel state.
can be operated in reciprocating motion independently of each other. Further, the side portion 5 of the seat cushion 1 is fixed to the installation surface L in a stationary state.

On the other hand, as shown in the second figure, the lower end of the main part 4 of the seat bag 2 is rotatably connected to the main part 3 by a hinge 10 interposed between the main part 4 and the upper end of the main part 4 of the seat bag 2. It is movably connected and supported to the side part 6. Sliding pins 11 protrude in the vehicle width direction from both sides of the upper end of the main part 4, and the protruding ends of the sliding pins 11 are movably fitted into elongated holes 12 bored in the side parts 6.
Therefore, the main parts 3 and 4 are
The main part 4 follows the reciprocating movement of the sliding pin 11.
The backrest angle between the main part 3 and the main part 3 is variably adjusted by the cooperation of the elongated hole 12 and the main part 3, and the front edge of the main part 3 of the seat cushion 1 is made substantially flush with the front edge of the side part 5. At this time, the seating surface of the main portion 4 of the seat bag 2 is substantially flush with the seating surface of the side portion 6 thereof.

According to the embodiment configured as above,
In order to create a sitting comfort with a sense of hold, by moving the main part 3 of the seat cushion 1 in the direction of arrow X, the main part 4 of the seat back 2 is retracted as shown on the right side of FIG. Ru. In other words, the seating surface of the main part 4 of the seat bag 2 and the side part 6
A step is formed between the front edge of the main part 3 of the seat cushion 1 and the side part 5 of the seat cushion 1.
A step is formed between the front edge of the Therefore,
By allowing the main part 3 of the seat cushion 1 to support the buttocks and leaning back against the main part 4 of the seat bag 2, the side parts 5 can be placed on both sides of the seated person's body from the buttocks to the armpits. The rear part and the side part 6 extend along the side part 6 in a protruding state, and the front part of the side part 5 is arranged in a protruding state on both sides around the calf. As a result, the person seated on the seating portion formed by the main portions 3 and 4 can enjoy the comfort of sitting in a stable holding state due to the side portions 5 and 6.

In addition, in order to create a relaxing feeling when sitting, the main part 3 of the seat cushion 1 is moved back in the direction opposite to the arrow By doing so, the main portion 4 of the seat bag 2 is pushed out as shown on the left side of FIG. In other words, the seating surface formed by the main portions 3 and 4 and the seating surface formed by the side portions 5 and 6 are smoothly continuous, resulting in a general seating surface state of a normal seat. Therefore, the seated person can enjoy the comfort of sitting in a relaxed state in which the hold by the side portions 5 and 6 described above is released.

Furthermore, according to the embodiment, in the case of a rear seat of a car, the position where the main part 2 can move back in the Y direction is set in such a state that the front edges of the main part 2 and the side parts 5 are close to each other. Therefore, it is possible to prevent the above-mentioned disadvantage that the footrest space between the front seat and the front seat becomes narrow when the user is seated in a relaxed manner.

In addition, in the present invention, by holding the main part 3 by the link L that stands upright when the main part 3 is located forward and collapses when moving backward, the main part 3 is held in a low position when it moves backward. As a result, the protruding surface P side becomes flush with the surface of the side portion 5, making it easier to sit on the seat.

As explained above, according to the present invention, the seat cushion that receives the buttocks of the seated person and the seat back constituting the backrest are each divided into a main part and side parts arranged on both sides of the main part, and the seat back The main part and the main part of the seat cushion are rotatably connected by a hinge, and sliding pins are provided to protrude outward from the upper ends of both sides of the main part of the seat bag.
A state in which the main parts of the seat bag and seat cushion are supported in a reciprocating manner relative to the side parts by fitting into elongated holes formed in the inner walls of the side parts of the seat bag corresponding to the both sides, and the main parts are placed in the forefront. Since the main part was made to be approximately flush with the side parts, as the main part of the seat cushion moved forward, the main part of the seat bag was retracted, and the main part was placed on both sides of the main part. A holding feeling can be created by the step formed between the seat back and the side section, and the above-mentioned step is canceled by causing the main section of the seat back to protrude as the main section of the seat cushion moves back. By doing so, you can create a feeling of relaxation. Moreover, since the hold seating and the relaxing seating can be formed by the same mechanism, the structure is simpler than that of conventional seats, and there is a practical effect that it can be implemented at low cost.
