Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seat cushion used in the driver's seat of an automobile equipped with a clutch pedal.

(Conventional technology) Conventional seat cushions for driver's seats include:
For example, the one shown in FIG. 3 is known.

In this conventional seat cushion, a support member 03 is provided on a floor 02 of the vehicle body located behind a clutch pedal 01, and the lower surface of a pad 04 formed of an elastic body is supported on the support member 03. The upper surface of 04 was covered with epidermis 05.

The pad 04 has a thicker rear portion that supports the driver's buttocks 06, and
The thickness of the front portion of the thigh 07 that supports the portion near the knee was formed to be symmetrically thin.

Therefore, the driver sinks his buttocks 06 into the thick rear part of the seat cushion of the pad 04, and places his thighs 06 into the thin front part of the pad 04.
The body part near No. 7's knees was held in a raised position.

(Problems to be Solved by the Invention) However, in the case of such conventional seat cushions, the thickness of the front part of the pad is symmetrical and thin, resulting in the following problems. Ta.

In cars equipped with a clutch pedal, the accelerator and brake pedals are operated with the right foot, and the clutch pedal is operated with the left foot. In contrast to the previous tilting movement, the left foot uses the base of the foot near the buttocks as a fulcrum, bending and stretching the knee, and when the clutch pedal is depressed, the knee is extended and the left foot is in a straight line. Trying to get closer.

Therefore, the part of the thigh of the right leg near the knee, which is located on the right front side of the seat cushion, hardly moves up or down even when the pedal is operated, and the pressing force against the seat cushion is large. It never changes.

On the other hand, the part of the thigh of the left leg near the knee, which is located on the left front part of the seat cushion, moves up and down as the knee bends and stretches, and the pressing force on the seat cushion increases as the clutch pedal is depressed. The left front portion of the seat cushion is compressively deformed.

Furthermore, when the clutch pedal is depressed, the left front portion of the seat cushion prevents the left foot from approaching a straight line due to its reaction force.

Therefore, in addition to the pressing force required to operate the clutch pedal, the left foot also requires force to compress and deform the left front part of the seat cushion in order to keep the left foot in a straight line, and the left foot exerts a correspondingly large amount of force. In addition, the clutch pedal becomes difficult to operate.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems, and as a means for achieving the purpose, the seat cushion for the driver's seat of the present invention In a seat cushion for a driver's seat, the lower surface of a pad formed of an elastic body is supported by a support member, and the upper surface of the pad is covered with an outer skin that serves as a seat surface. The thickness of the pad is such that the lower surface of the pad on the left side of the driver bulges downward and is thicker than the pad on the right side, and the support member is also provided with a step.

(Function) Therefore, in the seat cushion of the present invention, the thickness of the pad at the front side of the seat cushion is changed between the left and right sides, so that the thickness at the left front side of the pad is thicker than the thickness at the right front side. Therefore, the left front portion of the seat cushion can be compressed and deformed with less force.

(Example) Hereinafter, an example of the present invention is shown in FIGS. 1 and 2, and its configuration will be described in detail.

Reference numeral 1 denotes a driver's seat for a driver A to sit in. The driver's seat 1 is arranged on the floor 4 of the vehicle body behind a clutch pedal 2, an accelerator pedal 3, and a brake pedal (not shown). There is.

Reference numeral 5 designates a seat cushion according to an embodiment of the present invention, which is provided on the driver's seat 1 and is formed from a support member 6, a pad 7, and an outer skin 8.

A seat back 9 is rotatably provided on the seat cushion 5, and a head rest 10 is provided on the seat back 9.

The support member 6 is provided on the floor 4 so as to be slidable in the front-rear direction, and the support member 6 is
four mounting brackets 1 fixed to the floor 4;
1, 11, and 11 (one not shown), and consists of a lower rail 12a that is attached and fixed to the mounting bracket 11, and an upper rail 12b that slides in the front and back direction on the lower rail 12a, and is slidable in the front and rear direction. It has two parallel slide rails 12, 12, and the slide rail 1
Seat cushion frames 14, 14 fixed to the top rails 12b, 12b of 2, 12,
14, 14, and the frame 14, 1
It has several support pipes 13 intersectingly provided between the pipes 4, 14, and 14.

Incidentally, the upper rail 12b is detachably provided to the lower rail 12a by means of a locking device (not shown).

Further, the support pipe 13 has a front portion 15 high and a rear portion 16 low, and the front left portion 18 is lower than the front right portion 17. (When viewed in FIG. 1, which is a front view, the right side of the drawing is formed lower than the left side.) The pad 7 is provided so that its lower surface is supported by the support member 6. Padded 7
is formed of urethane foam, and the upper surface 19 is formed to slope gently downward to the rear, and the lower surface 20 is formed to match the shape of the support pipe 13, and the rear portion 21 is formed downward. The front portion 22 is thicker than the front portion 22, and is thicker than the front portion 22.
Also in the front part 22, the left front part 24 protrudes downward and is formed to be about twice as thick as the right front part 23, which has the same thickness as the conventional one. (If you look at FIG. 1, which is a front view, the right side of the drawing is thicker than the left side.) The skin 8 covers the pad 7 and forms a seat surface. It is formed by.

Next, the operation of the embodiment will be explained.

When the front part of the seat cushion 5 is pressed, as shown by the chain line in Fig. 1, the left part, which is about twice as thick as the right part, which has the same thickness as the conventional one, deforms about twice as much. Become.

Therefore, when the clutch pedal 2 is operated with the left foot, as shown in FIG. The left foot can be compressed and deformed without interfering with the clutch pedal, reducing the force required by the left foot in addition to the force required to press the clutch pedal.

Further, the ability to hold the driver A can be ensured by the buttocks. That is, the support member 6 is placed so that the front part 15 of the seat cushion 5 is raised and the rear part 16 is raised.
Since the rear part 21 of the pad 7 is made thicker than the front part 22 of the seat cushion 5, the driver's buttocks sink down and the thighs are supported so that they are higher. Now, support member 6
Since the height of the pad 7 and the thickness of the pad 7 are the same on the left and right sides of the seat cushion, the holdability is maintained.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in the embodiment, the left front portion of the pad 7 is made thicker by protruding downward, but it may be made thicker by protruding vertically.

Further, a lifter device may be provided to move the support portion of the pad 7 on the left front side portion of the support member 6 up and down, so that the left front side portion of the seat cushion can be moved up and down.

(Effects of the Invention) As described above, according to the seat cushion of the present invention, the left side of the front portion of the seat cushion can be compressed and deformed with a small amount of force. It is possible to reduce the force required to compress and deform the seat cushion in addition to the clutch pedal depression force when operating the clutch pedal with the left foot, thereby reducing left leg fatigue and improving the operability of the clutch pedal. can get.

Furthermore, in the seat cushion 5 of the embodiment, in addition to the above-mentioned effects, the rear part of the pad 7 is thicker than the left and right front parts, so that when the driver A is seated, his buttocks sink.
