Publication number: 20220316458Abstract: A remote actuator includes one or more bi-stable strips with at least one shape memory composite (SMC) spring connected to each bi-stable strip. The SMC spring includes a thermoplastic and an electrical and/or thermal conductor for transforming the length of the SMC spring upon heating. The contraction of the SMC spring transforms the bi-stable strip from its coiled stable state to its elongated stable state. The displacement of the SMC spring can be amplified by a simple machine included in the remote actuator. The remote actuator can include a shape memory alloy (SMA) strip for transforming the bi-stable strip from its elongated stable state to it curved stable state upon heating. Heating can be by Joule heating or from an adjacent heat source.Type: ApplicationFiled: March 30, 2021Publication date: October 6, 2022Inventors: Ryohei Tsuruta, Brian J. Pinkelman, Umesh N.

Publication number: 20220307485Abstract: An actuator for a vehicle seat can be configured to prevent overstress of a shape memory alloy (SMA) wire. The actuator can include a first body member and a second body member pivotably connected to each other. The actuator can include an overstress post and an overstress contact plate operatively connected to the overstress post. Thus, movement of the overstress post causes movement of the overstress contact plate. The actuator can include an overstress contact pin. The actuator can include an SMA wire operatively connected to one of the body members and to the overstress post. When activated, the SMA wire can shrink, causing one of the body members to pivot relative to the other body member and causing the overstress contact plate to move toward the overstress contact pin. If the overstress contact plate contacts the overstress contact pin, the SMA wire can be deactivated.Type: ApplicationFiled: March 23, 2021Publication date: September 29, 2022Inventors: Mark A.

Publication number: 20220242328Abstract: A cargo organizer is constructed from one or more bi-stable strips with at least one shape memory alloy (SMA) actuator per bi-stable strip. The cargo organizer can reside in the bi-stable strips elongated (flat) stable state and require little or no volume of the cargo compartment that it resides. Upon actuating a SMA actuator, the rapid conversion to the curved stable state can occur with the formation of a barrier to partition the cargo compartment into at least to portions. The transformation into the flat stable state removes the partition where the transformation can be via a second SMA actuator or manually. The cargo organizer can be incorporated into the cargo compartment in a manner that it translates from one site and orientation to one or more other sites or orientations by activation an actuator that can be an additional SMA actuator.Type: ApplicationFiled: February 2, 2021Publication date: August 4, 2022Inventors: Brian J.

Patent number: 11370330Abstract: A vehicle seat can be configured to selectively provide support to a vehicle occupant in conditions when lateral acceleration is experienced. An actuator can be located within the vehicle seat. When activated, the actuator cause a portion of the seat to morph into an activated configuration. The actuator can be activated based on vehicle speed, steering angle, and/or lateral acceleration. The actuator can include end members connected by a shape memory material connecting member. Actuator blocks with sliding surfaces can be located between the end members. The actuator can be configured such that, in response to an activation input, the shape memory material connecting member contracts, which draws the end members toward each other and causes corresponding sliding surfaces of the plurality of actuator blocks to engage and slide relative to each other. In this way, the actuator morphs into an activated configuration in which its overall height increases.Type: GrantFiled: March 22, 2019Date of Patent: June 28, 2022Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Miga Technologies.
