Title:
ACTIVE VEHICLE SEAT WITH MORPHING PORTIONS
Document Type and Number:
Japanese Patent JP2023138954
Kind Code:
A
Abstract:
To provide an active vehicle seat with morphing portions.SOLUTION: Actuators can be used in controlling a seat surface of a vehicle seat. The actuators can have an outer skin in connection with hinge assemblies. The actuators can include a shape-memory material (SMM) member operatively connected to the hinge assemblies. The SMM member can be a shape-memory alloy (SMA) wire. The SMM member can change from a first configuration to a second configuration in response to an activation input, such as heat. The input can be delivered to the SMM member upon detecting an activation condition, such as detection of lateral acceleration. The actuators are operatively positioned relative to a seat surface such that, when the SMM member changes the configurations, the actuators cause the seat surface to morph.SELECTED DRAWING: Figure 3
