Description

[Detailed Description of the Invention] During driving, such as a passenger car with relatively soft B seats or a truck with slightly hard J seats, vibrations occur due to periodic vertical vibrations of the elasticity of the spring body that supports the heavy body and changes in running acceleration. , Irregular vertical changes and rapid deviation changes occur on the seating surface of the seat due to the phenomenon of unevenness.

The present invention is designed to ensure that even if such a change occurs on the seating surface, the lobe (E) that acts as a cushion during use of the seat always remains in tight and elastic contact with the seating surface and is released. It fully realizes the kungjong effect, and even after long-term use, there is no disturbance or bias in the lobe arrangement.
It maintains a uniform rope surface, thereby preserving the original beauty of the cushion for a long time, preventing it from becoming an ugly distorted contour, and absorbing the force of body penetrating force due to changes in running acceleration. The purpose of the present invention is to eliminate defects such as the shoe/input slipping out of place and moving out of the seat.

At the end of the day, when I put this cushion on the seat M of a car and sit down, and when I put my weight on it, the kunon 9 was freely distorted into a concave curve at this center (with 0 as the bottom position). The thickness σ→ of the flexible robe becomes thick and soft to the touch, and it comes into close contact with the body surface in the shape of a protrusion I+', creating a kunjong effect along the curvature of the seat surface (goods).

Generally speaking, the car body constantly vibrates up and down due to the periodic amplitude of the spring body that supports the running vehicle and the car body, and this vertical movement acts as an external force that is applied to the laying surface, causing the seating surface and the surface of the car to become free. Therefore, the Kunjing effect is lost, and the acceleration change of the running vehicle causes a penetrating force to form in the extra-thick body, and the penetrating and opening force of 5. / It looks at the harmful effects such as movement.

The cushion according to the present invention effectively acts against external forces that are one of the causes of the above-mentioned adverse effects. , ,jl! Utilizing the space seat 1 in which the three axes of 1. It would be convenient to explain.

Approximately the center of
This shows the vertical direction of the rabbit axis, which includes a dimension 'f' in both axis planes.

Longitudinal direction ((A legible lobe (2) that does not allow expansion and contraction is a fixed length and expands outward in a spiral glJ (J) shape from the central position of the seat base D) Since the lobe rings are arranged in such a way that they are fixed to each other, each lobe ring in this arrangement will expand in the direction of 2) if the ring diameter is reduced and the ring diameter is allowed to shrink inward. First, the above-mentioned configuration of this robe is unacceptable.

On the other hand, due to the spiral spiral structure of the cushion holder of the present invention, this face piece can be easily moved in the front axis direction, that is, in the vertical direction of the Kuno no 9j face piece without showing much resistance.
KIEN 1] 1'l's cushion seat has the characteristic of facilitating three-dimensional transformation from a planar shape to a conical or pyramidal shape.

This characteristic is formed when the above-mentioned single flexible lobe passes through the adjacent space 1. The lamp is a plane body arranged in a spiral ring shape, and without breaking this arrangement, it is extended into an I-spiral three-dimensional shape, that is, in the X-axis direction, and again the spiral three-dimensional shape in the diagram '1 is shown.
Allowing for deformation extremely easily by reducing the ring diameter.

Next, the n-type expandable cross section of the bellows (A) of Honori no Noyon is:
In this (c, the opposing lobe cross-sections are perpendicular to each other in the longitudinal direction of the lobe, and a series of spiral rings U) form a chiruko bellows (Aj prisoner 3H-----t
A) Row (rJ), allowing relative expansion and contraction in one motion, that is, in the χ axis direction.

Furthermore, the concave grooves (B) are also arranged in a series of spiral spiral rings (J) 11 having the same shape as above, and the connecting line of this bottom surface (2) is
) is also a series of spiral spiral rings (J) having the same shape as the above, so both the concave groove (B) and the connecting line (2) easily follow the helical three-dimensional deformation of the rope (2) ring, and these This is due to the fact that the ring diameter is forced to be reduced, which also allows for helical three-dimensional deformation.

Therefore, when laying the seat on a seat surface that is concave, gently hang the lower back and buttocks on the upper surface of the lower back. If the car runs along 11 and becomes a downward curved surface, then Q '', the body weight is applied to all of these by the oscillating external force, and the seated body surface lobes (2) and the ring array are
John will be operating the company.

This external force causes a small movement amplitude, but the speed changes (7) Sudden, that is, the acceleration is large and the force is strong.1. -1 is the characteristic.

1 In this case, since the seating load which becomes the pre-pronation curved surface is not allowed to expand this spiral ring diameter, the inward gate ring diameter is uniformly As it shrinks, it is forced to move in the X-axis direction and deform into a spiral three-dimensional shape, as the vehicle body moves violently up and down. This external force i is extremely large and appears to prompt the above deformation.

In this way, due to the external forces of the seating load and vertical vibration, there is one lobe [F] that is forced to move in the gtb direction. Thus, the cope with which this external force is applied, the connecting line (
F′) through the groove (B) of the elastic floor base (r)).
+ and the entire spiral ring (J) of this bottom surface (2) acts to tighten the shrinkage material.

5. The bottom surface (2) and the concave groove (B) are integrally formed, and a shrinkage strain is formed in the thin and elastic floor base (D), and this strain shape is caused by the elasticity. It becomes distorted and forms elastic energy that tries to halo into the original shape, but the spiral ring (J) of the wood is distorted in the vertical direction, that is, π, as shown in the previous figure.
Since the movement in the axial direction is extremely easy, the elastic mechanism formed in this way can be moved through the bellows.
Lobe spiral ring (J) is always the most active; This is something that is currently being realized.

Or < 1. Due to the strain elasticity formed by the floor base D) due to the vertical vibration of the seat surface, the wooden cushion is subjected to an external force in the direction of the leg axis during use of F.
The surface of the berthing body is in close contact with the surface of the seating body to alleviate the discomfort caused by vertical vibration. It becomes something that does not dissolve and does not release.

If you put it in the present invention, the seat surface is Z tlQl+
When moving up and down in the direction, the above explanation is n911- Figure 1 K
%-, knonyong f7') center position [0 must be 1.
Rather than placing it at the origin, place it at any location that is biased from this -14v center (C), for example (c).
l) The distortion relationship to the seat mj is realized so that it gives a torsion curved surface to the wooden seat mj. The up and down movement of the face of the sword in the direction of the sword axis corresponds to the taruhiro, and the close contact between the load face and the lobe ■ ring row 7 fully demonstrates the intended effect.

This is a spiral ring U)-shaped bellows [A] that allows free twisting and bending.
This is because the configuration of ) allows the cushion seat surface to be formed into a torsionally curved surface with increased resistance.

Even if it becomes ``, it will appear as ``relationship'', ``love'', and ``situation'', and it will perform the same work as above. [See Figure 1] Next, the external force that causes elastic distortion to occur in the floor base CD) and 1
At 7, there is physical power.

When a car is swaying, a sudden change in running acceleration, including in the case of a curve, causes the seated body to collapse due to sudden displacement, and this penetrating force formed by the body load moves in one constant direction. The external force applied to the tree laying 7/yon with the external force of lz makes a roar.

This penetrating force appears to be larger and higher than the above-mentioned external force due to vertical vibration.

Because this body-penetrating force is formed instantaneously, it always acts as a cushion on top of an external force that moves in one direction, and it is impossible for this external force to move in the opposite direction at the same time. ”
lO As mentioned above, the body in the seated position receives the vertical movement of the car body, which causes a vertical movement f′, but at this time, the body descending speed q and the free fall due to the movement of gravity Matches i-shahen.

Generally, when a car is running, the supporting spring body of the It body is activated in a lap 1υ1 which is faster than the body descent time, so the body load applied to the seat surface and the I John is If the situation is created instantaneously, and at the same time, the body-penetrating force is applied horizontally, there is a risk that the installed cushion will move and come off the seat surface. It is something to look at.

(Company), which has not yet been invented, uses the above-mentioned body-penetrating force as an external force on a fixed-length robe [F] ring that cannot be moved outward in the outer circumferential direction, and lays wood/John. As soon as it is applied to this external force, this spiral (J)-shaped connecting line ■
This is transmitted to m-<base ff)), and the following distorted shape is formed over the entire surface of the floor base.

In other words, the direction of the external force applied to the lobes on the upper surface of the wood ring, that is, the line of action of this external force, is the bellows (A+)k) of the part that is perpendicular to the line of action. (A1
) Due to the characteristics of this bellows (3), the newborn 'A (D) will try to expand as if stretching in the direction of the external force, and on the other hand, the part parallel to the line of action σ0 to σ0 of this external force. The bellows (A2) (A2)...(A2) row has a cross section of the bellows with a concave and convex continuous waveform, and has a normal 0.
Due to the flexible bar configuration in the direction perpendicular to the line of action, the floor base 0) approaches the line of action 00 of the external force so as to bend suddenly, and in this way, the elastic seat base D) It becomes distorted and forms stronger elastic energy. [See Figure 6] This distorted version of Sung Yeon's low profile) Drift,
Due to the greater elastic energy produced by the floor base D), the work of this greater upward or downward elastic force is realized more actively in the direction of the X-axis.

In this way, the density M between the seating body surface and the wood non-yon surface is increased, and it becomes possible to prevent the wooden cushion from shifting due to body-penetrating force.

In the invention for wood 2, the seating surface body (π) of wood 7
The lobe spiral extension part C), which was extended by extending the lobe ■ along the outer circumferential edge of the coil and adding a winding ring, extends to the extended parallel warp ■ width, and there is an encirclement, so it becomes a seated face body [π) K body. When a load is applied, the extension part IG) is uniformly pulled inward from this inner peripheral edge, and the parallel joined lobes collide with each other and try to rise upwards, but it is not suitable for seating. In the end cushion, which has an area suitable for sitting on, the extension part C) extending from the upper part receives the weight of the thigh, and the lobes abut each other. Then, a rigid circular body IL with a downward concave shape is fixed to all seats (goods). h
The peripheral edge of this face piece (π) acts as a support against the vertical movement in the X-axis direction, further promoting the effect in the X-axis direction. [See Figures 7 and 9] The material constituting the uninvented floor base D) is required to be a relatively stiff elastic body for passenger cars, and a relatively hard elastic body for trucks. For example, it is appropriate to use foamed polyethylene or foamed polypropylene, which can be freely adjusted to hardness or softness by adjusting the foaming rate, or to use a rubber material that can be finished into a similar elastic body. is also possible.

The spiral train of the lobe E), on which the body load is applied, is fixed to the floor base 0) through the connecting line F) over its entire length, so that the wooden non-yong is maintained for a long time. Even if you use
There is no disturbance in the spiral rows of the lobes, and therefore the cushion contour retains its original size, which has the effect of preventing ugly deformation.

In addition, in the backrest of a four-wheeled automobile, the same effect as described above is produced due to back pressure. Double shoes/
It can also be used for computers. [See Figure 10]
