Abstract

An adjustable suspended seat apparatus having a tuned frequency-tailored damping through stratified seat structure is described. The damping seat structure includes: a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer. A second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer, the first material or the second material having an adjustable damping characteristic. The suspended seat apparatus includes a seat base configured to have the seat coupled thereto; a suspension system coupled to the seat base, the suspension system comprising: an adjustment feature configured to adjust operation of the suspension system; and a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle.

Claims (51)

1. An adjustable suspended seat apparatus with damping seat structure comprising:

a damping seat structure, the damping seat structure comprising:

a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer;

a suspended seat apparatus, the suspended seat apparatus comprising:

a seat base configured to have the seat coupled thereto;

a suspension system coupled to the seat base, the suspension system comprising:

an adjustment feature configured to adjust operation of the suspension system; and

a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle;

said damping seat structure further comprises:

a second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer,

the first material or the second material having an adjustable damping characteristic; and

a first bonding material to bond the first material to the second material based on a third characteristic to provide a third damping effect,

the first layer bonded to the second layer using the first bonding material; and

said adjustable damping characteristic is manually adjustable via a user input or an automatic adjustment feature controllable based on input from a vehicle monitoring system.

2. The adjustable suspended seat apparatus with damping seat structure of claim 1 , further comprising:

at least one side of at least one of the first material and the second material being treated to alter a surface characteristic of the at least one side to provide a fourth damping effect.

3. The adjustable suspended seat apparatus with damping seat structure of claim 1 , wherein the second material is a piezoelectric material.

4. The adjustable suspended seat apparatus with damping seat structure of claim 1 , further comprising:

a third material from a plurality of materials having a pneumatic chamber therein to provide a fourth damping effect in a third layer,

the third layer bonded with the first layer or the second layer.

5. The adjustable suspended seat apparatus with damping seat structure of claim 1 , further comprising:

a third material from a plurality of hydraulic materials to provide a fourth damping effect in a third layer,

the third layer bonded with the first layer or the second layer.

6. The adjustable suspended seat apparatus with damping seat structure of claim 1 , further comprising:

a third material from a plurality of materials having a pneumatic chamber therein to provide a fourth damping effect in a third layer; and

a fourth material from a plurality of hydraulic materials based on a fourth characteristic to provide a fifth damping effect in a fourth layer,

the third layer and the fourth layer bonded with the first layer or the second layer.

7. The adjustable suspended seat apparatus with damping seat structure of claim 1 wherein said adjustable suspended seat apparatus is coupled to a vehicle.

8. A method of manufacturing an adjustable suspended seat apparatus, the method comprising:

selecting a first material from a plurality of materials based on a first characteristic to provide a first damping effect in a first layer;

selecting a second material from the plurality of materials based on a second characteristic to provide a second damping effect in a second layer;

selecting a first bonding material to bond the first material to the second material based on a third characteristic to provide a third damping effect;

bonding the first layer to the second layer using the first bonding material to form a seat; and

coupling the seat with a suspension system, said suspension system comprising:

an adjustment feature configured to adjust operation of the suspension system; and

a chassis mount coupled with the suspension system, the chassis mount configured to be coupled to a vehicle;

wherein said first material or said second material has an adjustable damping characteristic, and said adjustable damping characteristic is manually adjustable via a user input or an automatic adjustment feature controllable based on input from a vehicle monitoring system.

9. The method of claim 8 , further comprising:

treating at least one side of at least one of the first material and the second material to alter a surface characteristic of the at least one side to provide a fourth damping effect.

10. The method of claim 8 , further comprising:

selecting the first and/or second material from a plurality of piezoelectric materials.

11. The method of claim 10 , further comprising:

selecting a third material from a plurality of hydraulic materials based on a third characteristic, a pneumatic chamber therein, to provide a fourth damping effect in a third layer; and

bonding the third layer with the first layer or the second layer.

12. The method of claim 11 , further comprising:

selecting a fourth material from a plurality of hydraulic materials based on a fourth characteristic to provide a fifth damping effect in a fourth layer; and

bonding the third layer and the fourth layer with the first layer or the second layer.

13. The method of claim 8 , wherein said enabling adjustment of said suspension system further comprises:

providing a manual and/or automatic adjustment feature which is configured to adjust operation of said suspension system.

14. The method of claim 13 , further comprising:

controlling said automatic adjustment feature based on input from a vehicle monitoring system.
