Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle seat whose seating comfort can be adjusted according to a person's preference.

[Prior Art] As shown in Figure 5, a vehicle seat is equipped with a seat cushion 101 which serves as a seating area, a seat back 102 which serves as a backrest, a reclining device (not shown) which adjusts the angle between the seat cushion 101 and the seat back 102, and a slide mechanism 103 which fixes the underside of the seat cushion 101 to the vehicle body so that the position can be freely adjusted in the fore-aft direction.

The seat cushion 101 includes a cushion frame 105 formed in a substantially frame shape, a retainer 106 attached to a required portion of the cushion frame 105, a plurality of S springs 107 attached to the retainer 106, and these S springs 107.
The pad 108 placed on top and this pad 10
trim cover 10 that is attached to cover 8;
9 and an ohm clip 110 for fixing the end of the trim cover 109 to the cushion frame 105.

Further, the seat bag 102 is also constructed in the same manner as the seat cushion.

[Problem to be solved by the invention] In recent years, there has been a demand for such vehicle seats to be able to adjust the stiffness of the S spring 107 according to the preferences of the seated person and the condition of the road surface. strong.

However, in conventional vehicle seats,
In order to meet such requirements, the S spring 107
Therefore, the ohm clip 10, retainer 106, etc. must be removed using a special tool or the like.

Therefore, there was a problem in that the hardness of the S spring 107 could not be easily changed.

In view of the above circumstances, it is an object of the present invention to provide a vehicle seat that can easily change the hardness of the seat depending on the seat occupant's preferences, road surface conditions, etc.

[Means for Solving the Problems] In order to achieve the above object, a vehicle seat according to the present invention includes a seat cushion and a seat back, in which a pad and a cushion constituting the seat cushion are provided. The seat cushion is characterized in that a magnetic generating body is provided in the cushion frame, and the repulsive force between these magnetic generating bodies is adjusted to adjust the sitting comfort of the seat cushion.

[Function] With the above configuration, the sitting comfort of the seat cushion is improved by adjusting the repulsive force generated between the magnetic generating body provided on the pad and the magnetic generating body provided on the cushion frame. Adjust.

[Embodiment] FIG. 1 is a side view showing an embodiment of a vehicle seat according to the present invention.

The vehicle seat shown in this figure includes a seat cushion 1 as a seating part, a seat back 2 as a backrest, a reclining device 3 for adjusting the angle between the seat cushion 1 and the seat back 2, and a reclining device 3 for adjusting the angle between the seat cushion 1 and the seat back 2. The seat cushion 1 is provided with a slide mechanism 4 that fixes the lower surface of the cushion 1 to the vehicle body side so as to be adjustable in its longitudinal position, and a cord 5 that connects the seat cushion 1 and a battery (not shown).

As shown in FIG. 2, the seat bag 2 includes a cushion frame 10 formed in a substantially frame shape, a retainer 11 attached to a required portion of the cushion frame 10, and a plurality of S springs 12 attached to the retainer 11. , these S springs 12
It includes a pad 13 placed on top and a trim cover 14 attached to cover this pad 13.

The seat cushion 1 also includes a pipe frame 16 formed in a frame shape, a square deep dish-shaped bracket 17 attached to this pipe frame 16, and a planar electromagnet 18 attached to the inner bottom surface of this bracket 17. , a pad 19 attached to the top side of the pipe frame 16, a plurality of permanent magnets 20 embedded in the bottom of the pad 19, a trim cover 21 attached to cover the pad 19, and the trim cover 21.
Strength adjustment switch 2 attached to the side part of
2 (see Figure 1).

As shown in FIG. 3, the electromagnet 18 and the permanent magnet 20 have opposite surfaces having the same polarity (for example, S
The magnetic force generated when the electromagnet 18 is energized and each permanent magnet 20

9 upwards.

By switching the strength adjustment switch 22, the magnetic force of the electromagnet 18 changes, and the repulsive force between the electromagnet 18 and each permanent magnet 20 changes. By this, for example, the intensity adjustment switch 2
If the strength adjustment switch 22 is set to weak, the seat cushion 1 will sink deeply in the seated state as shown in Fig. 4a, and if the strength adjustment switch 22 is set to strong, the seat cushion 1 will sink too much as shown in Fig. 4b. You can prevent it from sinking.

In this way, in this embodiment, the amount of depression of the seat cushion 1 can be adjusted simply by operating the strength adjustment switch 22, so that the hardness of the seat can be adjusted according to the preference of the seated person and the condition of the road surface. can be easily changed.

Further, in the embodiment described above, one electromagnet 18 is used to energize each permanent magnet 20, but the electromagnet 18 is divided into a plurality of electromagnets,
The amount of depression of the seat cushion 1 may be partially adjusted by individually adjusting the strength of each electromagnet.

[Effects of the Invention] As explained above, according to the present invention, the hardness of the seat can be easily changed according to the preferences of the seated person, the condition of the road surface, and the like.
