Abstract
An anti-submarining seat cushion for a vehicle includes a main body constructed of an anisotropic material. The anisotropic material includes a primary material including a primary stiffness and a plurality of inserts that are dispersed throughout the primary material. The plurality of inserts exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, where the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.

An anti-submarining seat cushion for a vehicle, the anti-submarining seat cushion comprising:
- a main body constructed of an anisotropic material, the anisotropic material comprising:
- a primary material including a primary stiffness;
- and
- a plurality of inserts that are dispersed throughout the primary material, wherein the plurality of inserts exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, wherein the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.
A vehicle seat assembly, comprising:
- a seat pan;
- an anti-submarining seat cushion supported by the seat pan, wherein the anti-submarining seat cushion comprises:
- a main body constructed of an anisotropic material, the anisotropic material comprising:
- a primary material including a primary stiffness;
- and
- a plurality of inserts that are dispersed throughout the primary material, wherein the plurality of inserts are oriented to exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, wherein the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.
An anti-submarining seat cushion for a vehicle, the anti-submarining seat cushion comprising:
- a main body constructed of is constructed of a primary material having a primary stiffness and a secondary material having a secondary stiffness, wherein an elastic storage modulus of the secondary material is at least twenty-five percent greater than an elastic storage modulus of the primary material, and a region of the main body is constructed of the secondary material and is shaped to conform with a pelvis and a upper thigh region of an occupant, and a region of the main body is constructed of the secondary material and is shaped to abut against the pelvis when the vehicle undergoes a sudden deceleration.
