Artificial muscle actuators

A hinge-type actuator device in accordance with the present disclosure may include a first and second paddle, a first and second artificial muscle actuator segment, and a plurality of contacts, where the first and second artificial muscle actuator segments are actuated via the contacts, actuation of the first artificial muscle actuator segment causes the first and second paddle to open the hinge-type actuator, and actuation of the second artificial muscle actuator segment causes the first and second paddle to close the hinge-type actuator.

ARTIFICIAL MUSCLE ACTUATORS

An actuator device that includes a first fiber, a conducting material, and a coating. The coating coats the first fiber or the conducting material. The coating may also provide moisture protection, UV protection, thermal insulation and thermal conductivity.

Seat with shape memory material member actuation

A vehicle seat can be configured to provide support to a vehicle occupant in conditions when lateral acceleration is experienced. Shape memory material members can be operatively positioned with respect to a seat portion of the vehicle seat. The shape memory material members can be selectively activated by an activation input. When activated, the shape memory material members can engage a seat pan so as to cause the seat pan to tilt in a respective lateral direction. As a result, a seat cushion supported by the seat pan can also tilt in the respective lateral direction. The seat cushion can be tilted in a lateral direction that is opposite to the direction of the lateral acceleration. Thus, the effects of lateral acceleration felt by a seat occupant can be reduced. The shape memory material members can be selectively activated based on vehicle speed, steering angle, and/or lateral acceleration.
