Abstract

A seat cushion structure for use in a vehicle seat including a first outer wall and a second outer wall joined to form a plurality of chambers. The seat cushion includes an energy absorption substance disposed within the chambers to absorb occupant load. The seat cushion also includes a plurality of springs disposed within the chambers to further facilitate occupant support and comfort.

Claims

1. A seat cushion structure for use in a vehicle seat, the cushion structure comprising:

a first outer wall joined to a second outer wall to form a plurality of inner walls, the outer walls and inner walls together defining a cushion member having a plurality of chambers;

one or more compression members disposed within at least some of the plurality of chambers to absorb occupant load; and

the cushion member further defining a first side bolster, a second opposed side bolster, a front side, an opposed rear side, an upper surface having a raised portion at the first and second side bolsters, and an opposed lower surface.

2. The seat cushion structure of claim 1, wherein each of the plurality of chambers has a predetermined shape.

3. The seat cushion structure of claim 1, further comprising an energy absorption substance disposed within the chambers.

4. The seat cushion structure of claim 1, wherein the compression members are springs.

5. The seat cushion structure of claim 4, wherein the springs have varying size.

6. A seat cushion structure for use in a vehicle seat, the cushion structure comprising:

a first outer wall joined to a second outer wall to form a plurality of inner walls, the outer walls and inner walls together defining a cushion member having a plurality of chambers;

one or more springs disposed within at least some of the chambers to absorb occupant load;

a support substrate attached to the second outer wall to provide support; and

the cushion member further defining a first side bolster, a second opposed side bolster, a front side, an opposed rear side, an upper surface having a raised portion at the first and second side bolsters, and an opposed lower surface.

7. The seat cushion structure of claim 6, wherein the springs have varying size.

8. A seat base cushion structure for use in a vehicle seat, the cushion structure comprising:

a cushion member having a first outer wall joined to a second outer wall to form a plurality of inner walls, the outer walls and inner walls together defining a plurality of chambers, the cushion member further defining a first side bolster, a second opposed side bolster, a front side, an opposed rear side, an upper surface having a raised portion at the first and second side bolsters, and an opposed lower surface;

a first set of springs disposed within at least some of the chambers to absorb occupant load, wherein the first set of springs is arranged in a first row from the cushion member front side to the cushion member rear side; and

a second set of springs disposed within at least some of the chambers to absorb occupant load, wherein the second set of springs is arranged in a second row from the cushion member front side to the cushion member rear side, wherein the first and second set of springs serve to straddle and support occupants.

9. The seat base cushion structure of claim 8 further comprising a structural support substrate adjacent the cushion member, wherein the first set of springs or second set of springs is secured to the structural support, such that either the first set of springs or second set of springs absorb energy from an impact collision.

10. The seat base cushion structure of claim 8 further comprising a structural support substrate that at least partially encloses the cushion member.
