Abstract

Embodiments of present invention may include a cushion pad for supporting a seated passenger; the cushion pad being divided into a left pad section, a middle pad section and a right pad section; a soft resin foam dispersed throughout the left pad section, the middle pad section and the right pad section; the left pad section having a left holding volume for holding a first volume of an elastic three-dimensional fibrous network and the soft resin foam; the right pad section having a right holding volume for holding a second volume of an elastic three-dimensional fibrous network and the soft resin foam; and the middle pad section not having a volume of an elastic three-dimensional fibrous network contained within.

Claims

1. A cushion pad for a car seat where an occupant is seated, comprising:

a cushion pad for supporting a seated passenger;

the cushion pad being divided into a left pad section, a middle pad section and a right pad section;

a soft resin foam dispersed throughout the left pad section, the middle pad section and the right pad section;

the left pad section having a left holding volume for holding a first volume of an elastic three-dimensional fibrous network and the soft resin foam;

the right pad section having a right holding volume for holding a second volume of an elastic three-dimensional fibrous network and the soft resin foam; and

the middle pad section not having a volume of an elastic three-dimensional fibrous network contained within.

2. A cushion pad of claim 1, wherein:

a cross-section of the left holding volume has at least one linear side; and

a cross-section of the right holding volume has at least one linear side.

3. A cushion pad of claim 1, wherein:

the left pad section has an upper surface and a lower surface,

the right pad section has an upper surface and a lower surface,

the first volume of elastic three-dimensional fibrous network spans from the upper surface to the lower surface of the left pad section; and

the second volume of elastic three-dimensional fibrous network spans from the upper surface to the lower surface of the right pad section.

4. The cushion pad of claim 1,

wherein the first volume of an elastic three-dimensional fibrous network and/or the second volume of an elastic three-dimensional fibrous network includes a plurality of filament loops wherein contact portions between the plurality of filament loops are bonded together.

5. The cushion pad of claim 4,

wherein the plurality of filament loops are comprised of at least one polyester, polyamide, polyether or polyolefin thermoplastic.

6. The volume of elastic three-dimensional fibrous network used in a cushion pad for a vehicle of claim 1.

7. A cushion for a vehicle comprising:

a cushion having a main pad section and two lateral support sections;

the main pad section being divided into a left pad section, a middle pad section and a right pad section;

wherein the two lateral support sections contain soft resin; and

the main pad section contains a combination of soft resin and a volume of elastic, fibrous material.

8. The cushion for a vehicle of claim 7,

wherein the volume of elastic, fibrous material of the main pad section is confined to the left pad section and the right pad section.

9. The cushion for a vehicle of claim 7,

wherein the left pad section and the right pad section are arranged outside of the tuberosity of the ischium of the cushion.

10. The volume of elastic, fibrous material used in the cushion for a vehicle of claim 7,

wherein the volume of an elastic, fibrous material includes a plurality of filament loops wherein contact portions between the plurality of filament loops are bonded together.

11. The volume of elastic, fibrous material of claim 10, wherein the plurality of filament loops are comprised of at least one polyester, polyamide, polyether or polyolefin thermoplastic.
