Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a motor vehicle seat with side supports.

(Prior Art) It is generally known that in an automobile seat, side supports are provided on both sides of a seat cushion so that the body of an occupant can be supported from both sides. For example, Japanese Utility Model Publication No. 58-131753 discloses a seat cushion in which side supports can be moved up and down on both sides of a seat cushion.

Further, in general, many automobile seats have a seat back rotatably supported on a seat cushion by a reclining means. This reclining means allows the occupant to take a desired posture by appropriately selecting the inclination angle of the seat back, and is important in providing a comfortable seat for many people of different physiques. When installing side supports in a seat with such reclining means, it is necessary to form a gap between the seat back and the side supports to avoid interference between the rotatable seat back and the rear end of the side supports. .

(Problem 8 to be solved by the invention) By the way, in racing cars that require quick steering and gear changing operations, the seat is required to be able to hold the driver's driving posture, especially to prevent the upper body from collapsing. In this case, it is important to support the occupant's private parts and shoulders. The seat of this racing car, which allows occupants to maintain their posture reliably, is also important in improving maneuverability and reducing driving fatigue in general passenger cars.

However, in the case of conventional seats with side supports, although the side supports have the function of holding the occupant's body more securely, providing a reclining means to make the seat fit many people with different physiques as mentioned above Since a gap is formed between the back and the side supports, the occupant's private parts cannot be sufficiently supported from both sides. In particular, if the driver increases the angle of rearward inclination of the seat back in order to adopt his or her preferred driving position, the gap between the seat back and the side supports will increase accordingly, sacrificing the ability of the side supports to maintain the driving position. It's something I have to become.

Further, although the above-mentioned reclining means is usually provided beside the rear end of the seat cushion, there is a problem in that it is difficult to cover this reclining means with a cover or the like so as not to spoil the appearance.

(Means for Solving the Problems) The present invention solves these problems by integrating the side supports with the seat backs in a seat with a reclining means, thereby making it possible to reliably support the occupant's private parts from both sides. In addition, the reclining means can be covered with side supports so as not to be exposed to the outside.

That is, the automobile seat having side supports according to claim (1) is an automobile seat in which a seat back is rotatably supported on a seat cushion by a reclining means, and side supports are provided on both sides of the seat cushion, The side supports are characterized in that they protrude forward from both sides of the seat back and rotate integrally with the seat back.

Further, the automobile seat having a side support according to claim (2) is the invention according to claim (1), wherein the reclining means is provided inside the rear end of the side support and selects and locks a reclining angle. A mechanism, an operating lever protruding from the front end of the side support to operate the reclining mechanism, and a linking member disposed inside the side support to transmit the movement of the operating lever to the reclining mechanism. be.

(Function) In the automobile seat according to claim (1) above, since the side supports protrude forward from both sides of the seat back, the portions extending from both sides of the seat back to the side supports reliably support the occupant's private parts from both sides. be able to. Even when the seat back is tilted backwards using the reclining means, the side supports rotate together with the seat back, and there is no gap between the seat back and the side supports, thereby maintaining the occupant's driving posture. There is no problem.

In the automobile seat according to claim (2), the reclining mechanism is provided inside the side support, and the linking member between the operating lever protruding from the front end of the side support and the reclining mechanism is also provided inside the side support. Only the operating lever protrudes to the outside, and the other parts are covered by the side supports, so that the side supports function as a cover for the reclining means.

(Effect of the invention) Therefore, according to the invention of claim (1), since the side supports are made to project forward from both sides of the seat back and rotate integrally with the seat back,
The part extending from both sides of the seat back to the side supports can reliably support the occupant's private parts from both sides, and even when the seat back is reclined, there is no gap between the seat back and the side supports, helping to maintain the occupant's driving posture. This improves the vehicle's maneuverability, and reduces the risk of driving symptoms even when driving for long periods of time.

Further, according to the invention of claim (2), only the operating lever of the reclining means protrudes outside and the other parts are covered by the side supports, and the side supports are used as covers for the reclining means. This eliminates the need for side supports, and the appearance can be easily improved by covering with side supports.

(Example) Embodiments of the present invention will be described below based on the drawings.

In the automobile seat shown in FIG. 1, 1 is a seat cushion, 2 is a seat back, and 3 is a side support.

The seat cushion 1 can be moved back and forth and fixed to the floor 4 of the automobile by a sliding means 5, and the seat back 2 is rotatably supported by the seat cushion 1 by a reclining means 6. There is. The side support 3 is integrated with the seat back 2.

That is, as shown in FIG. 2, the seat back 2 includes a backrest portion 2a that supports a portion extending from the waist to the back of the occupant;
A headrest 2b is provided above the upper end of the backrest part 2a with a gap 18 between it and the upper end of the backrest part 2a. As shown in the figure, shoulder holder parts 2c, 2c are provided which are inclined diagonally forward. In addition, the shoulder holder parts 2c, 2c have side edges that are inclined toward the center of the seat and become narrower as they go downward, and the amount of forward protrusion from the backrest portion 2a decreases downward. It is decreasing accordingly.

Then, the side support 3 extends from the lower end where the shoulder holder portion 2C of the seat back 2 has the smallest amount of lateral overhang and forward overhang, to the lower part of the backrest 2a and the lower part of the seat cushion 1. The upper surface of the seat cushion 1 extends forward to near the front part of the seat cushion 1 while tilting the upper surface diagonally downward to the front along both sides.

Further, inside the seat back 2, there is provided an annular reinforcing frame 7 extending from the headrest 2b through the shoulder holder parts 2c and 2c to the lower part of the backrest part 2a. Reinforcement frames 8 to 10 are respectively connected to the annular reinforcement frame 21 and arranged in the shoulder holder 2C.

The reclining means 6 includes a reclining mechanism 11 that selects and locks a reclining angle, an operating lever 12 that operates the reclining mechanism 11, and a linking member 13 that transmits the movement of the operating lever 12 to the reclining mechanism 11. The reclining mechanism 11 has an accommodation space 16 formed by a reinforcing plate 14 of the side support 3 and a cover 15 as shown in FIG.
The operating lever 12 protrudes from the front end of the side support 3.

That is, as shown in FIG. 6, the left and right reinforcing plates 14
．． 14 is rotatably provided on a support shaft 17 fixed to the seat cushion 1 at the rear end of the side support 3. The reclining mechanism 11 includes a ratchet 21 fixed to the spindle 17 and a bin 2 to the reinforcing plate 14.
A lock pawl 24 is rotatably supported at 2 and urged in a direction away from the ratchet 21 by a spring 23;
4 against the ratchet 21, and a pressing release position where the ratchet 4 is evacuated clockwise in FIG. It consists of a biased cam 27. On the other hand, the operating bar 12 has its base end pivotally attached to the front end of the reinforcing plate 14 with a pin 28.

The cam 27 and the operating lever 12 are linked to a linking member (rod) 13 that passes through the inside of the side support 3 in the front-rear direction, and the operating lever 12 is connected to a locking claw by a spring 29 via the linking member 13 and the cam 27. 24 is biased in the direction of engaging the ratchet 21.

Therefore, in the above automobile seat, the seat back 2
The part extending from both sides to both side supports 3.3 can reliably support the private part of the occupant A from both sides. Also, the left and right shoulder holders part 2c.

Because 2c is tilted forward while protruding outward,
The shoulders of the occupant A are held from both sides by the shoulder holders 2c, 2c.

The shoulder holder portions 2c, 2c become narrower as they go downwards, and the amount of forward protrusion from the backrest portion 2a decreases, so that they can be used to operate the handle 19 or the gear change lever 20. This prevents the upper arm from interfering with the seat, making this gear change operation easier.

When the operating lever 12 is pulled up against the bias of the spring 29, the cam 27 rotates clockwise, and the lock pawl 24 is no longer pressed against the ratchet 21, causing the ratchet 21 and the lock pawl 24 to engage with each other. (reinforcing play) 14, that is, seat back 2
can be rotated rearward at a desired reclining angle.

Then, when the operation lever 12 is released from being pulled up, the seat back 2 and the side supports 3 are locked at the selected reclining angle.

Then, when the seat back 2 is tilted backward in this way, the side supports 3 are integrated with the seat back 2, so they rotate together with the seat back 2, and the relationship between the seat back 2 and the side supports 3 is There is no gap between them. In other words, regardless of whether or not the seat back 2 is reclined, the occupant A can move from both sides of the seat back 2 to the side supports 3 and 3.
